Description

Embodiments of the present invention relate to the field of communication, in particular to paging message transmission methods, base stations, and user equipment.

In existing communication systems, user equipment (UE, user equipment) first receives a control channel and is transported on a data channel scheduled by the control channel according to the control information in the received control channel. The size of (TBS, Transport Block Size) is determined, and data reception is started only after the transport block size is determined. For example, in Long Term Evolution (LTE) systems, the control channels are Physical Downlink Control Channel (PDCCH) or Enhanced Physical Downlink Control Channel (EPDCCH), and The data channel may be a physical downlink shared data channel (PDSCH, Physical Downlink Shared Channel). The user equipment determines the size TBS of the transport block carried by PDSCH from PDCCH or EPDCCH. Before the data channel is received, the control channel represents the TBS of the transport block carried over the data channel. Therefore, if necessary, the TBS value of the transport block carried on the data channel may change.

In existing LTE systems, idle UEs need to listen for paging messages to determine whether the network side or base station will paging the UE. A UE in the connected state needs to listen for a paging message to determine if the system information has been updated. The paging message sent by the base station to the UE is carried on the data channel, and the data channel is scheduled by the control channel. Therefore, when listening for a paging message, the UE must first discover the control channel that schedules the paging message. The data channel carrying the paging message is received only after the control channel is successfully detected, following the instructions of the control channel.

When the UE successfully detects the data channel carrying the paging message for the idle UE, the UE must match the paging UE ID carried in the paging message with the paging UE ID of the UE. If the match is successful, that is, the paging UE ID of the UE is the same as the one paging UE ID carried in the paging message, the UE determines that the network side or base station paging the UE. Otherwise, the UE determines that the paging message indicates that the UE is not paging.

The paging message may include one or more paging UE IDs. Therefore, the paging message may be used to page one or more UEs. As mentioned above, the UE only successfully detects the control channel and the paging message scheduled by the control channel to see if the paging message indicates that the UE is paging, or if the paging message updates the system message. You can decide whether to show it. The UE can successfully detect the control channel and the paging message scheduled by the control channel, but the paging message does not indicate when the UE is paging, or the paging message does not indicate an update of system information. I can't find it. Therefore, there is a problem that the power consumption of the UE is wasted. Wasted power consumption is crucial, especially for low-cost or low-complexity user equipment.

When coverage is enhanced, the data channel carrying the paging message needs to be iteratively transmitted in order to ensure reliable transmission. If the transmission of the data channel carrying the paging message needs to be based on the scheduling performed by the control channel, the UE must first successfully discover the control channel and then follow the instructions of the control channel for paging. Further discover the data channel carrying the message. In this case, in order for the UE to normally receive the data channel carrying the paging message, the control channel must be repeatedly transmitted, and the data channel carrying the paging message must also be repeatedly transmitted. As a result, system resource overhead increases, network resource utilization decreases, and UE detection complexity and power consumption overhead increase significantly.

It does not indicate. The terms used in such a manner are interchangeable in the appropriate circumstances, indicating that this is merely an identification method used when objects with the same attributes are described in embodiments of the present invention. I want to be understood. In addition, the term "include, contain" and any other variant means that a process, method, system, product, or device that includes a set of units covers a non-exclusive inclusion. Such units may include, but are not necessarily limited to, other units that are not explicitly listed or unique to such processes, methods, systems, products, or devices.

First, the system architecture to which the paging message transmission method in the present invention is applied will be briefly described. The present invention is mainly applied to LTE systems or Long Term Evolution Advanced (LTE-A, LTE Advanced) systems. Further, the present invention also provides, for example, a broadband code division multiple access, provided that there is an entity capable of transmitting information in the communication system and another entity capable of receiving information in the communication system. It may be applied to another communication system such as (Wideband Code Division Multiple Access, WCDMA®) or a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. For example, the information is a paging message.

Referring to FIG. 1, FIG. 1 is a system architecture diagram of a communication system to which the paging message transmission method according to the present invention is applied. As shown in FIG. 1, a base station and user equipment (UE, User Equipment) 1 to UE6 form a communication system. In a communication system, a user device is sometimes called a terminal, and a base station sends a RAR message to one or more of UE1 to UE6. The base station is a transmitting device in the paging message transmitting method of the present invention, and UE1 to UE6 are receiving devices in the paging message transmitting method of the present invention. UE4 to UE6 also form a communication system. In a communication system, UE5 may be implemented as a function of a base station, and UE5 may send a RAR message to one or more of UE4 to UE6.

In the following, details will be described individually.

The embodiment of the paging message transmission method in the present invention can be applied to the paging message transmission by the base station. With reference to FIG. 2, the paging message sending method can include the following steps.

201. The instruction information contained in the first paging message is determined, and the instruction information is used to instruct the user equipment (UE) to receive the first paging message and / or to receive the second paging message. used.

In this embodiment of the invention, the idle UE needs to listen for paging messages and decide whether the network side or base station will paging the UE. A UE in the connected state needs to listen for a paging message to determine if the system information has been updated. The paging message sent by the base station to the UE is carried over the data channel. The base station adds instructional information to the paging message rather than using the control channel to perform scheduling. The transport block used by the base station to send the paging message may be indicated by instructional information, eliminating the need for the UE to detect the control channel and reducing the power consumption of the UE.

In this embodiment of the present invention, when transmitting the first paging message to the UE, the base station needs to add instruction information to the first paging message. The instructional information is used to instruct the UE to receive the first paging message and / or the second paging message. The instructional information determined by the base station indicates whether the UE will receive paging messages and which paging messages should be received.

202. A first paging message containing instructional information is sent, and the first paging message is contained in the first transport block.

In this embodiment of the present invention, the base station determines the instruction information included in the first paging message, and the base station transmits the first paging message including the instruction information. Specifically, the base station can use the first transport block to send the first paging message. In this case, the terminal first acquires the instruction information, and the terminal completes the reception of the first paging message according to the instruction information. Further, if the instruction information indicates a second paging message, the terminal can further receive the second paging message.

203. When the instruction information instructs the user device to receive the second paging message, the second paging message is sent, the second paging message is contained in the second transport block, and the second transport. The block and the first transport block are different transport blocks that are transmitted separately.

In this embodiment of the present invention, if the base station further generates a second paging message after the base station transmits the first paging message, the base station indicates that the second paging message is also present. Informed, the base station uses a second transport block to send a second paging message. Note that the second transport block and the first transport block are two transport blocks that are transmitted separately. The base station first transmits the first transport block and then the second transport block. Each transport block is transmitted separately, i.e. one of the two transport blocks is transmitted separately to the peer device (ie, UE). Separate transmission of transport blocks can allow peer devices to receive transport blocks one at a time. The paging messages carried by different transport blocks are different. Different transport blocks can be sent separately. For example, coding and / or rate matching, as well as mapping, are performed separately for different transport blocks.

To reduce the power consumption used by the UE to detect paging messages, the base station determines the identity of the UE that needs to be paging, two or more paging UEs for implementation. It can be divided into sub IDs. The first paging message contains the paging user equipment sub-identity (ID), multiple sub-IDs corresponding to the same UE form the paging UE ID, and the paging UE sub-ID contains some information of the paging UE ID. And / or the second paging message contains another paging UE sub-ID that forms the paging UE ID. That is, the paging UE ID is divided into two paging UE sub IDs, each paging UE sub ID contains some information of the paging UE ID, and the two paging UE sub IDs obtained by the paging means are each. It is carried by the first paging message and the second paging message. Similar to this implementation, in another implementation, the paging UE ID is split into three paging UE sub IDs, two paging UE sub IDs are carried in the first paging message, and the other paging UE sub IDs are second. It may be carried by the paging message of. Similarly, the paging UE ID may instead be split into four paging UE sub-IDs, with two paging UE IDs being carried in the first paging message and the other two paging UE IDs being second. It is carried by a paging message.

The number of sub-IDs split from the paging UE ID may be preset or indicated by signaling. For example, the base station first determines the number of paging UE sub-IDs according to a predefined definition, and the number of paging UE sub-IDs may be specified by the system, eg, higher than the base station as specified by the MME. It may be specified by the device. Both the base station and the terminal determine the number of paging UE sub-IDs according to a predefined definition. In another example, the base station first receives the signaling that the signaling originates from an entity such as a system or MME. The base station determines the number of paging UE sub-IDs according to the signaling received. In addition, for all sub-IDs that form the paging UE ID, the number of sub-IDs carried in the first paging message and the second paging message after the number of sub-IDs split from the paging UE ID has been determined. The number of sub-IDs carried in may be preset or indicated by signaling. For example, the number of sub-IDs carried in the paging message may be preset by the system or may be determined by the base station using the signaling received from the system. For example, z indicates the number of all subIDs of the paging UE ID, x indicates the number of paging UE subIDs carried in the first paging message, and y indicates the number of paging UE subIDs carried in the second paging message.

In another embodiment of the invention, the format of the first paging message transmitted by the base station in step 202 may be determined by one of the following methods. Specifically, the paging message transmission method provided in this embodiment of the present invention is:
A1: Steps to determine the format of the first paging message according to the predefined, or
A2: It may further include one of the steps of self-determining the format of the first paging message and using signaling or implicit instructions to notify the peer device of the determined format of the first paging message. ..

If the base station needs to determine the format of the first paging message, the base station may determine the format of the first paging message by either method A1 or A2. For example, the base station first determines the format of the first paging message according to a predefined definition. The format of the first paging message may be specified by the system, for example, by the higher-level device of the base station as specified by the MME. Both the base station and the terminal determine the format of the first paging message according to a predefined definition. As another example, the base station may set the format of the first paging message itself, self-determine the format of the first paging message, and then notify the peer device (eg, terminal). The self-determined format of the first paging message can meet the requirements of the base station itself. The format of the first paging message may be determined according to the resource transmission state of the base station itself. For example, the base station may format the first paging message according to bandwidth, or may format the first paging message according to whether the base station is currently idle or busy. Good.

Further, in the implementation scenario of step A2, the signaling transmitted by the base station is one or more carried by the first paging message, system information, radio resource control signaling, media access control signaling, or physical layer signaling. It may be instructional information. In other words, in step A2, the signaling notified to the peer device used by the base station may be instructional information or system information, or the signaling is specifically radio resource control signaling, media access control signaling, Alternatively, it may be physical layer signaling. The particular signaling format for use may be determined according to the application scenario and is not limited herein.

In some embodiments of the present invention, the instructional information carried in the first paging message may be system information update instructional information, earthquake and tsunami warning system (etws: Earthquake and Tsunami Warning System) instructional information, or commercial. Includes one or more of the instruction information of the Mobile Alert Service (CMAS). The particular signaling format for use may be determined according to the application scenario and is not limited herein.

In some embodiments of the present invention, a method of setting the paging UE ID in the paging message can be further shown, that is, the instruction information includes setting information indicating the paging UE ID. The setting information of the paging UE ID is the quantity indication information of the ID whose paging UE ID type is the international mobile subscriber identity (IMSI), and the paging UE ID type is the temporary mobile subscriber identification number (MSI). S-TMSI, SAE Temporary Mobile Station Identifier) ID quantity indication information, type is IMSI paging UE sub ID value indication information, type is S-TMSI paging UE sub ID value indication information, type is Contains one or more of the location indication information for the paging UE sub-ID that is the IMSI, the location indication information for the paging UE sub-ID of type S-TMSI, or the indication information for the paging UE ID type.

Time resource information, frequency resource information of the second paging message, power setting information of the second paging message, paging UE ID type information included in the second paging message, paging UE ID included in the second paging message. Contains one or more of the quantity information or the structural information of the second paging message.

In another embodiment of the invention, the first paging message may include instructional information, and the second paging message may also include instructional information. The instructional information in the second paging message is used to indicate the second paging message and / or to indicate the third paging message. That is, if the base station generates a second paging message and a third paging message, the instruction information can be added to the second paging message, and the instruction information is used to indicate the third paging message. To. The structure and contents of the instruction information here may be the same as the structure and contents of the instruction information carried in the first paging message, and the description of the instruction information in the above-described embodiment can be referred to. Details will not be described again here.

In some embodiments of the invention, the paging UE ID contained in the first paging message may be indicated by other information carried in the first paging message. For example, the time resource information and / or frequency resource information used to send the first paging message may be used to indicate some paging UE ID or paging UE sub ID. For example, the paging UE ID may include three sub-IDs. The first sub-ID may be indicated by the time resource information and / or frequency resource information used to send the first paging message, and the second and third sub-IDs are the second. It may be carried by the instruction information of the first paging message and the second paging message, respectively. According to this method, the overhead of the paging message can be reduced, so that the utilization efficiency of system resources is improved and the power consumption consumed by the UE to detect the paging message is reduced. In other words, the UE can analyze the time resource information and the frequency resource information to obtain some paging UE IDs, and the UE does not need to further determine the paging UE ID, thus reducing the power consumption of the UE. Will be done.

As can be seen from the above description of the embodiment of the present invention, the instruction information contained in the first paging message is first determined, and this instruction information is used to receive the first paging message and / or the first. The user equipment (UE) is instructed to receive the second paging message, the first paging message containing the instruction information is transmitted, the first paging message is included in the first transport block, and this instruction information is included. When instructing the user equipment to receive a second paging message, a second paging message is sent, the second paging message is contained in the second transport block, and the second transport block. And the first transport block is a different transport block that is transmitted separately. When the instruction information contained in the first paging message indicates the second paging message, the second paging message is also sent. The first paging message and the second paging message are sent separately using different transport blocks, and the first paging message sent first indicates the second paging message sent next. Can be used for. According to the first paging message received first, the terminal can receive the second paging message transmitted next. You do not need to use a control channel to schedule transport blocks, and you have the flexibility to resize the transport block for paging messages. Therefore, the network resource occupancy is relatively small, the detection of the control channel by the user equipment is avoided, and the detection power consumption of the user equipment is reduced.

In the above embodiment, the paging message transmission method is described from the viewpoint of the base station side. Hereinafter, the paging message transmission method of the present invention will be described from the viewpoint of the peer device (terminal) of the base station. With reference to FIG. 3, the paging message transmission method according to another embodiment of the present invention can include the following steps.

301. The instruction information contained in the first paging message is acquired, and the instruction information is the related information used to receive the first paging message and / or to instruct to receive the second paging message. is there.

In this embodiment of the invention, the idle UE needs to listen for paging messages and decide whether the network side or base station will paging the UE. A UE in the connected state needs to listen for a paging message to determine if the system information has been updated. The paging message sent by the base station to the UE is carried over the data channel. The base station adds instructional information to the paging message rather than using the control channel to perform scheduling. The transport block used by the base station to send the paging message may be indicated by instructional information, eliminating the need for the UE to detect the control channel and reducing the power consumption of the UE.

In this embodiment of the present invention, when transmitting the first paging message to the UE, the base station needs to add instruction information to the first paging message. The instructional information is used to instruct the UE to receive the first paging message and / or the second paging message. Therefore, the UE must first obtain the instructional information contained in the first paging message, and the UE determines whether to receive the paging message and which paging message to receive according to the instructional information. .. The base station does not schedule the transport block using the control channel, and the instructions for the paging message sent by the base station to the terminal are obtained by the UE by parsing the instruction information.

302. The first paging message and / or the second paging message is determined according to the instruction information, the first paging message is contained in the first transport block, and the second paging message is contained in the second transport block. The first transport block and the second transport block are different transport blocks that are transmitted separately.

In this embodiment of the present invention, after the UE determines the instruction information included in the first paging message, the UE receives the first paging message according to the instruction information. The UE gets the first paging message from the first transport block, and if the instruction information indicates the second paging message, the UE gets the second paging message further from the second transport block. be able to. Note that the second transport block and the first transport block are two transport blocks that are transmitted separately. The base station first transmits the first transport block and then the second transport block. Each transport block is transmitted separately, i.e. one of the two transport blocks is transmitted separately to the peer device (ie, UE). Separate transmission of transport blocks can allow peer devices to receive transport blocks one at a time. The paging messages carried by different transport blocks are different. Different transport blocks can be sent separately. For example, decryption and / or rate matching, as well as mapping, are performed separately for different transport blocks.

To reduce the power consumption used by the UE to detect paging messages, the base station determines the identity of the UE that needs to be paging, two or more paging UEs for implementation. It can be divided into sub IDs. The first paging message contains the paging user equipment sub-identity (ID), multiple sub-IDs corresponding to the same UE form the paging UE ID, and the paging UE sub-ID contains some information of the paging UE ID. And / or the second paging message contains another paging UE sub-ID that forms the paging UE ID. That is, the paging UE ID is divided into two paging UE sub IDs, each paging UE sub ID contains some information of the paging UE ID, and the two paging UE sub IDs obtained by the paging means are each. It is carried by the first paging message and the second paging message. Similar to this implementation, in another implementation the paging UE ID is split into three paging UE sub IDs, two paging UE IDs are carried in the first paging message, and the other paging UE sub IDs are second. It may be carried by a paging message. Similarly, the paging UE ID may instead be split into four paging UE sub-IDs, with two paging UE IDs being carried in the first paging message and the other two paging UE IDs being second. It is carried by a paging message.

The number of sub-IDs split from the paging UE ID may be preset or indicated by signaling. For example, the UE first determines the number of paging UE sub-IDs according to a predefined definition, and the number of paging UE sub-IDs may be specified by the system, eg, the base station's superior device as specified by the MME. May be specified by. The UE determines the number of paging UE sub-IDs according to a predefined definition. In another example, the UE first receives the signaling, which originates from the base station, system, MME, and so on. The UE determines the number of paging UE sub-IDs according to the signaling received. In addition, for all sub-IDs that form the paging UE ID, the number of sub-IDs carried in the first paging message and the second paging message after the number of sub-IDs split from the paging UE ID has been determined. The number of sub-IDs carried in may be preset or indicated by signaling. For example, the number of sub-IDs carried in the paging message may be preset by the system or determined by the UE using signaling received from the base station. For example, z indicates the number of all subIDs of the paging UE ID, x indicates the number of paging UE subIDs carried in the first paging message, and y indicates the number of paging UE subIDs carried in the second paging message. Indicates the number of paging UE sub-IDs. In this case, z = x + y, where the values of z are invariant, and the values of x and y may be preset or indicated by signaling.

The length of the paging UE sub-ID contained in the second paging message and associated with the paging UE ID is determined by one of the methods preset or indicated by signaling. Can be done.

The length of the sub-ID split from the paging UE ID may be preset or indicated by signaling. For example, the UE first determines the length of the paging UE sub-ID according to a predefined definition, and the length of the paging UE sub-ID may be specified by the system or by the host device of the base station. Alternatively, it may be indicated by signaling from the base station. The UE determines the length of the paging UE sub-ID according to a predefined definition. In another example, the UE first receives the signaling and the signaling originates from the base station. The UE determines the length of the paging UE sub-ID according to the signaling received. In addition, for all sub-IDs that form the paging UE ID, which sub-ID of a given length is carried in the first paging message and which sub-ID of a given length is carried in the second paging message. It may be preset or indicated by signaling. For example, which sub-ID of a given length is carried in the paging message may be preset by the system or may be determined by the UE using signaling received from the base station.

In another embodiment of the invention, the format of the first paging message determined by the UE according to the instructional information in step 302 may be determined by one of the following methods. Specifically, the paging message transmission method provided in this embodiment of the present invention is:
B1: Steps to determine the format of the first paging message according to the predefined, or
B2: The step of receiving the signaling and determining the format of the first paging message according to the received signaling, or
B3: It may further include one of the steps to determine the format of the first paging message according to the implicit instructions.

If the UE needs to determine the format of the first paging message, the UE can determine the format of the first paging message by any of steps B1, B2, and B3. For example, the UE first determines the format of the first paging message according to a predefined definition. The format of the first paging message may be specified by the system, for example, by the higher-level device of the base station as specified by the MME. The UE determines the format of the first paging message according to a predefined definition. In another example, the UE receives the signaling transmitted by the base station. The base station self-determines the format of the first paging message, and after self-determining the format of the first paging message, notifies the peer device (for example, a terminal). The self-determined format of the first paging message can meet the requirements of the base station itself. The format of the first paging message may be determined according to the resource transmission state of the base station itself. In yet another example, the UE can follow the implicit instructions to get the format of the first paging message. For example, the UE determines the format of the first paging message from the new fields used in the existing information.

Further, in the implementation scenario of step B2, the signaling transmitted by the base station is one or more carried by the first paging message, system information, radio resource control signaling, media access control signaling, or physical layer signaling. It may be instructional information. In other words, in step B2, the signaling notified to the peer device used by the base station may be instructional information or system information, or the signaling is specifically radio resource control signaling, media access control signaling, Alternatively, it may be physical layer signaling. The particular signaling format for use may be determined according to the application scenario and is not limited herein.

In some embodiments of the present invention, the instructional information carried in the first paging message may be system information update instructional information, earthquake and tsunami warning system (etws: Earthquake and Tsunami Warning System) instructional information, or commercial. Includes one or more of the instruction information of the Mobile Alert Service (CMAS). The particular signaling format for use may be determined according to the application scenario and is not limited herein.

In some embodiments of the invention, the instructional information can further indicate how to set the paging UE ID in the paging message, i.e., the instructional information includes setting information indicating the paging UE ID. The paging UE ID setting information includes quantity indication information for an ID whose paging UE ID type is IMSI, quantity indication information for an ID whose paging UE ID type is S-TMSI, and value indication information for a paging UE sub ID whose type is IMSI. , Value indication information for a paging UE subID of type S-TMSI, location indication information for a paging UE subID of type IMSI, location indication information for a paging UE subID of type S-TMSI, or paging UE Contains one or more of the ID type instruction information.

In some embodiments of the invention, the instructional information can further indicate a second paging message. Specifically, the instruction information included in the first paging message includes the size information of the second paging message, the modulation information of the second paging message, the encoding information of the second paging message, and the second paging message. Time resource information, frequency resource information of the second paging message, power setting information of the second paging message, paging UE ID type information included in the second paging message, paging UE ID included in the second paging message. Contains one or more of the quantity information or the structural information of the second paging message.

In another embodiment of the invention, the first paging message may include instructional information, and the second paging message may also include instructional information. The instructional information in the second paging message is used to indicate the second paging message and / or to indicate the third paging message. That is, if the base station generates a second paging message and a third paging message, the instruction information can be added to the second paging message, and the instruction information is used to indicate the third paging message. To. The structure and contents of the instruction information here may be the same as the structure and contents of the instruction information carried in the first paging message, and the description of the instruction information in the above-described embodiment can be referred to. Details will not be described again here.

In some embodiments of the invention, the step of determining the first paging message and / or the second paging message in step 302 according to the instructional information is specifically:
Of the transport block size of the second paging message, the structure of the second paging message, or whether the second paging message exists, according to the instructions contained in the first paging message or the first paging message. It may include a step of determining one or more of.

Specifically, after acquiring the instruction information contained in the first paging message, the UE may determine whether or not the second paging message exists according to the instruction information contained in the first paging message. It can further determine the transport block size and structure of the second paging message if it is determined that a second paging message exists. In this way, the UE receives the second paging message according to the determined transport block size of the second paging message.

In some embodiments of the invention, in step 302, the step of determining the first paging message and / or the second paging message according to the instructional information is specifically:
If there is no paging UE subID that matches the determined first paging message, the step to stop receiving the second paging message, or
If there is a paging UE subID that matches the first paging message, it may include the step of receiving the second paging message.

Specifically, the UE first detects the paging UE sub-ID in the first paging message. If the sub-ID does not match the UE's paging UE sub-ID, it indicates that the base station did not send a paging message to the UE. The paging UE subID in the first paging message is detected first. If the sub-ID matches the paging UE sub-ID of the UE, it indicates that the UE needs further detection. In this case, the UE needs to receive the second paging message according to the instruction information of the first paging message and obtain another paging UE sub ID from the second paging message. If another sub-ID also matches the UE's sub-ID, it indicates that the base station has sent a paging message to the UE. If there is a paging UE subID that matches the determined first paging message, and there is no paging UE subID in the determined second paging message, it is determined that the UE is not paging. Alternatively, if there is a paging UE subID that matches the determined first paging message and there is a paging UE subID that matches the determined second paging message, then the UE is determined to be paging. Will be done.

In some embodiments of the invention, the paging UE ID contained in the first paging message may be indicated by other information carried in the first paging message. For example, the time resource information and / or frequency resource information used to send the first paging message may be used to indicate some paging UE ID or paging UE sub ID. For example, the paging UE ID may include three sub-IDs. The first sub-ID may be indicated by the time resource information and / or frequency resource information used to send the first paging message, and the second and third sub-IDs are the second. It may be carried by the instruction information of the first paging message and the second paging message, respectively. According to this method, the overhead of the paging message can be reduced, so that the utilization efficiency of system resources is improved and the power consumption consumed by the UE to detect the paging message is reduced. In other words, the UE can analyze the time resource information and the frequency resource information to obtain some paging UE IDs, and the UE does not need to further determine the paging UE ID, thus reducing the power consumption of the UE. Will be done.

As can be seen from the description of the above-described embodiment of the present invention, the instruction information contained in the first paging message is acquired first, and the instruction information receives the first paging message and / or the second paging. Relevant information used to instruct to receive a message, the first paging message and / or the second paging message is determined according to the instruction information, and the first paging message is the first transport block. The second paging message is contained in the second transport block, and the first transport block and the second transport block are different transport blocks transmitted separately. When the instruction information contained in the first paging message indicates the second paging message, the second paging message is also sent. The first paging message and the second paging message are sent separately using different transport blocks, and the first paging message sent first indicates the second paging message sent next. Can be used for. According to the first paging message received first, the terminal can receive the second paging message transmitted next. You do not need to use a control channel to schedule transport blocks, and you have the flexibility to resize the transport block for paging messages. Therefore, the network resource occupancy is relatively small, the detection of the control channel by the user equipment is avoided, and the detection power consumption of the user equipment is reduced.

In the following, in order to better understand and implement the above solution in the embodiment of the present invention, the corresponding application scenario will be described in detail as an example.

The transport block size of the first paging message is preset, preconfigured, or indicated by signaling. For example, the transport block size of the first paging message is indicated by system information. The transport block size of the first paging message is preset or preconfigured. Therefore, when the UE receives the first paging message, it determines the transport block size of the first paging message and then receives the first paging message.

The transport block size of the second paging message is variable and is preset, indicated by the first paging message, or determined according to the first paging message. Since the transport block size of the second paging message is variable, the size of the second paging message can be flexibly adjusted to adaptively adjust the paging capacity.

In this embodiment of the invention, the paging message contains information about one or more paging UE IDs. In particular, the paging message may be an empty message instead.

In this embodiment of the invention, the paging UE ID may include multiple paging UE sub-IDs. That is, the paging UE sub-ID contains some information about the paging UE ID. In particular, the paging UE sub ID may be equivalent to the paging UE ID, or the paging UE sub ID is empty. For example, paging UE ID1 = (paging UE ID1a, paging UE ID1b, paging UE ID1c) is established. Here, the commas in parentheses represent the cascade relationship.

More specifically, assuming that the length of the paging UE ID is 40 bits, the paging UE ID can contain two paging UE sub-IDs. For example, the length of each paging UE subID is 20 bits. In another example, the paging UE ID is 40 bits long and the paging UE ID may include three paging UE sub-IDs. The length of the paging UE subID is 15 bits, the length of the other paging UE subID is 15 bits, and the length of the other subID is 10 bits.

The number of paging UE sub-IDs forming the paging UE ID and the length of the paging UE sub-ID may be preset, preconfigured, or indicated by instructional information. For example, the instructional information in the first paging message indicates the length of the paging UE sub-IDs that form the paging UE ID and / or the number of paging UE sub-IDs.

The UE always listens for paging messages at a determined point in time (such as wireless frames and / or wireless subframes), but in practice most of the time, the paging messages that the UE listens to are the UE being paged. Does not show that. That is, the UE wastes a lot of power when listening for a paging message indicating that the UE is not paging. Paging messages need to be sent repeatedly, especially if coverage is enhanced. Therefore, the power consumption overhead becomes large. From this point of view, the UE may first listen for smaller messages, which carry some information about the paging UE ID (ie, the paging UE sub-ID). The UE detects this smaller message first. When the UE discovers that some information on the paging UE ID does not match the UE's ID (or paging UE sub-ID), the base station or network side decides not to paging the UE. In this case, the UE stops receiving the paging message, which significantly reduces the power consumption of the UE. When the UE finds that some information on the paging UE ID matches the paging UE ID (or paging UE sub-ID) of the UE, it determines that the base station or network side can paging the UE. In this case, the UE must continue to receive the paging message in order for the base station or network side to decide whether to actually paging the UE.

The first paging message can have one or more formats. The system or standard can predefine the format used by the first paging message. Alternatively, the base station (or system) uses an explicit or implicit method to indicate the format of the first paging message. For example, the format of the first paging message is indicated by the instructional information of the first paging message. Referring to FIG. 4-a, FIG. 4-a is a schematic configuration diagram of a paging message according to an embodiment of the present invention. Each paging UE ID contains two paging UE sub IDs. The first paging message carries the first paging UE subID of the four UEs, and the second paging message carries the second paging UE subID of the four UEs. The paging UE ID1 contains ID1a and ID1b, the paging UE ID2 contains ID2a and ID2b, the paging UE ID3 contains ID3a and ID3b, and the paging UE ID4 contains ID4a and ID4b. The first paging message carries ID1a, ID2a, ID3a, and ID4a, and the second paging message carries ID1b, ID2b, ID3b, and ID4b.

The UE first receives the first paging message. When the UE finds that the paging UE sub-ID carried in the first paging message matches the first paging UE sub-ID in the UE's paging UE ID, the paging message sent by the base station Determine that the UE can indicate that it has been paged. In addition, the UE detects a second paging message, which carries the second paging UE sub-ID of the aforementioned paging UE ID. If the paging UE sub-ID carried in the second paging message matches the second paging UE sub-ID in the UE's paging UE ID, the UE determines that the base station paging the UE. Otherwise, the UE determines that the base station or network side does not paging the UE.

If the UE finds in the first paging message that there is no paging UE sub-ID that matches the first paging UE sub-ID of the UE's paging UE ID, the UE will have the base station or network side paging the UE. Decide not to. In this case, the UE stops receiving the second paging message, which reduces the complexity of detecting the paging message by the UE and reduces the power consumption of the UE.

Specifically, for example, the paging UE ID of UE1 is paging UE ID 1, and paging UE ID 1 includes paging UE ID 1a and paging UE ID 1b. When the base station or network side paging UE1, the first paging message carries the paging UE ID 1a and the second paging message carries the paging UE ID 1b. UE1 detects the first paging message first. If UE1 discovers that the first paging message contains paging UE ID 1a, UE1 determines that the base station or network side can page the UE. In addition, UE1 detects the second paging message first. If UE1 discovers that the second paging message contains paging UE ID 1b, UE1 determines that the base station or network side paging the UE. If UE1 discovers that the second paging message does not include paging UE ID1b, UE1 determines that the base station or network side does not paging the UE. Indeed, if UE1 discovers that the first paging message does not include paging UE ID 1a, UE1 determines that the base station or network side does not paging the UE.

In order to indicate the update of the system information of the UE in the connected state, the instruction information in the first paging message may include information indicating the update of the system information. For example, the first paging message can include system update information (systemInfoModification). If there is systemInfoModification, the UE determines that the system information is updated (or the system information can be updated, or some system information is updated).

Optionally, there are many types of paging UE IDs, and different types of paging UE IDs may have different lengths. In order to flexibly support different types of paging UE ID in the first paging message, the instruction information of the first paging message can indicate the paging UE ID setting information or the configuration information. The transport block size of the first paging message is determined, and therefore the first paging message with the determined size can indicate a different type of paging UE ID. In addition, the transport block size of the first paging message was determined, and thus a variable amount of paging UE (ie, the number of UEs paged as the first paging message indicates) was determined. Supported by a first paging message with size, it enables flexible system design.

For example, if the IMSI is twice as long as the S-TMSI, then the paging bit length of the UE with UE ID type IMSI should support paging for two UEs with UE ID type S-TMSI. Can be done. Moreover, the IMSI is generally rarely used as a paging UE ID. However, in some scenarios, only the IMSI can be used to page the UE. Therefore, paging messages need to be supported even if the paging UE ID is IMSI. In this case, the base station needs to indicate to the UE whether the paging UE ID in use is S-TMSI or IMSI. In addition, the base station can further indicate the number of UEs whose paging UE ID is based on the S-TMSI and the number of UEs whose paging UE ID is based on the IMSI.

For example, assuming that the size of the first paging message is 120 bits, only the S-TMSI based paging UE subID is included in the first paging message. If the length of each paging UE subID is 20 bits, the first paging message can contain the paging UE subID of 6 UEs, that is, the first paging message to 6 UEs. Can be used to initiate paging. If each paging UE subID is 10 bits long, the first paging message can contain 12 UE paging UE subIDs, i.e. the first paging message to 12 UEs. Can be used to initiate paging. In this way, the number of UEs to be paged can be adaptively adjusted to meet the paging message capacity requirements of the network while the size of the first paging message remains the same.

Further, the instruction information in the first paging message can indicate paging UE ID (or paging UE sub ID) setting (or configuration) information. For example, the paging UE ID setting (or configuration) information includes quantity indication information for an ID whose paging UE ID type is IMSI, quantity indication information for an ID whose paging UE ID type is S-TMSI, and paging UE whose type is IMSI. Sub-ID value indication information, paging UE sub-ID value indication information of type S-TMSI, paging UE sub-ID location indication information of type IMSI, paging UE sub-ID location of type S-TMSI Contains the instruction information, or one or more of the instruction information of the paging UE ID type.

It should be noted that the other information in the present invention may be an empty message, in which case the message structure of the first paging message does not include the other information. If the other message is not an empty message, the first paging message contains another message.

Hereinafter, a specific embodiment of the first paging message is provided.

It is assumed that the M bit of the instruction information is used for the S-TMSI setting. The M bits indicate the quantity indication information of the ID whose paging UE ID type is S-TMSI, the value indication information of the paging UE sub ID whose type is S-TMSI, and the location indication of the paging UE sub ID whose type is S-TMSI. May be used for information, or for setting one or more of the paging UE ID type directives. For example, suppose you use 2 bits for your S-TMSI configuration. With reference to Table 1, Table 1 shows the relationship between the 2-bit and the S-TMSI configuration. Lengths in the table may be measured in bits, decimal, or octal bytes.

Suppose the N bits in the instruction information are used for the IMSI configuration. The N-bit is the quantity indication information of the paging UE ID whose paging UE ID type is IMSI, the location indication information of the paging UE sub ID whose type is S-TMSI, and the value indication information of the paging UE sub ID whose type is IMSI. It may be used for one or more of these settings.

One or more independent, combined, or bitmap instructions may be used to perform the S-TMSI or IMSI settings. Independent instruction means that one field indicates one specific instruction information. A combination instruction means that one field indicates a plurality of specific instruction information. Bitmap instruction means that each bit in one field indicates specific instruction information. Indeed, it may be K bits instead for the combination settings performed for the S-TMSI and IMSI settings. Details are not described here.

With reference to Table 2 below, the IMSI configuration using 3 bits is shown in the table below. One bit is used to indicate the value of the paging UE sub-ID of type IMSI, and the other two bits are used to indicate the quantity of the paging UE ID of type IMSI. Optionally, the value of the paging UE subID of type IMSI may be immutable or preset. In this way, the directive information does not need to indicate the value of the paging UE subID of type IMSI.

In the first paging message, the position and / or size of the field carrying the instruction information may be immutable or preset. For example, the field indicating the instruction information in the first paging message is in the first (or last) position of the first paging message. Since the instruction information in the first paging message contains one or more types of instruction information, the position of a bit or field indicating a different type of instruction information in the instruction information field in the first paging message, And / or the size of the bit or field may also be invariant or preset.

If the first paging message contains a paging UE ID (or paging UE sub-ID) of type IMSI, then the position of the paging UE ID of type IMSI in the first paging message is immutable or Predefined. For example, it is predefined that a paging UE ID of type IMSI follows (or precedes) a field of instruction information. The bit length of a paging UE ID of type IMSI in the first paging message is determined by the number of paging UE IDs of type IMSI and the length of the paging UE ID of type IMSI. Similarly, the location of a paging UE ID of type IMSI in the first paging message can be defined.

If the first paging message contains both a paging UE ID (or paging UE sub ID) of type IMSI and a paging UE ID (or paging UE sub ID) of type S-TMSI, then the type is IMSI. The positional relationship between a paging UE ID (or paging UE sub-ID) and a paging UE ID (or paging UE sub-ID) of type S-TMSI is immutable or predefined. For example, a paging UE ID (or paging UE sub ID) of type IMSI always precedes a paging UE ID (or paging UE sub ID) of type S-TMSI. Alternatively, the first paging UE ID (or first paging UE sub ID) of type S-TMSI follows the last paging UE ID (or last paging UE sub ID) of type IMSI.

Referring to FIG. 4-b, FIG. 4-b is a schematic configuration diagram of another paging message according to an embodiment of the present invention. Figure 4-b shows the different structure of the first paging message, and the transport block size remains the same. For example, assume that the size of the transport block carrying the first paging message is 168 bits. The instruction information occupies 8 bits.

In the first structure shown in Figure 4-b, the first paging message contains instructional information and eight paging UE subIDs of type S-TMSI. The length of each paging UE subID of type S-TMSI is 20 bits.

In the second structure shown in Figure 4-b, the first paging message contains instructional information, two paging UE subIDs of type IMSI, and four paging UE subIDs of type S-TMSI. .. Each paging UE subID of type IMSI has a length of 40 bits and each paging UE subID of type S-TMSI has a length of 20 bits.

In the third structure shown in Figure 4-b, the first paging message contains instruction information, two paging UE subIDs of type IMSI, and two paging UE subIDs of type S-TMSI. .. Each paging UE subID of type IMSI has a length of 40 bits, and each paging UE subID of type S-TMSI has a length of 40 bits.

In the fourth structure shown in Figure 4-b, the first paging message contains instruction information, one paging UE subID of type IMSI, and two paging UE subIDs of type S-TMSI. .. The length of each paging UE subID of type IMSI is 80 bits, and the length of each paging UE subID of type S-TMSI is 40 bits.

In the fifth structure shown in Figure 4-b, the first paging message contains instructional information and two paging UE subIDs of type IMSI. The length of each paging UE subID of type IMSI is 80 bits.

The instruction information is the length of the paging UE subID of type IMSI, the number of paging UE subIDs of type IMSI, the length of the paging UE subID of type S-TMSI, or the type S-TMSI. Can indicate one or more of the number of paging UE subIDs that are.

As mentioned above, after receiving the first paging message, the UE needs to decide whether to receive the second paging message and / or whether the second paging message exists. If the UE needs to receive a second paging message, the UE needs to determine the transport block size of the second paging message and / or the structure of the second paging message. The UE may determine the transport block size of the second paging message, and / or the structure of the second paging message, and / or whether the second paging message exists, according to the first paging message. it can.

For example, the instruction information of the first paging message includes the size information of the second paging message, the modulation information of the second paging message, the encoding information of the second paging message, and the time resource information of the second paging message. Frequency resource information for the second paging message, power setting information for the second paging message, paging UE ID type for the second paging message, paging UE ID quantity for the second paging message, or second It can contain one or more of the paging message structures. Alternatively, the UE follows the instructions in the first paging message, the transport block size of the second paging message, and / or the structure of the second paging message, and / or whether the second paging message exists. Is implicitly determined.

Next, the second paging message corresponding to the first paging message shown in FIG. 4-b will be described. The second type of second paging message contains eight paging UE subIDs of type S-TMSI. The second type of second paging message contains four paging UE subIDs of type S-TMSI. There is no second paging message that corresponds to the first paging message in the third to fifth structures.

Indeed, the second paging message can contain instructional information instead. The specific usage and structure of the instruction information are the same as those described above. Details will not be described again here. Indeed, the instructional information in the second paging message can only be used to indicate the second paging message and / or to indicate the third paging message.

Alternatively, the second paging message may have a different message structure. For example, the second paging message contains only the first information, and the length (or size) of the first information is indicated by the first paging message or determined according to the first paging message. In another example, the second paging message contains only the first and second information, the first information is the same as above, and the second information follows the instructions in the first paging message. It is determined. In yet another example, the second paging message includes at least the first information, the second information and the instructional information, the first information and the second information being the same as described above. It should be noted that some of the instructional information in the present invention may be predefined or preset.

In addition, smaller length paging UE IDs may be used to reduce paging message overhead. Alternatively, some paging UE ID (or paging UE sub-ID) information is implicitly carried using the time resource information and / or frequency resource information used to send the paging message. Other paging UE ID information may be presented to the UE using signaling.

For example, the time of the UE's paging frame and / or paging occasion is determined according to the UE ID, and the UE ID is determined according to the IMSI. For example, the UE ID is equal to IMSI mod 1024. However, the base station receives only the UE ID information transmitted by the mobility management entity, and the base station cannot obtain valid paging UE ID information according to the UE ID information.

If the time of the UE paging frame and / or the time of the UE paging occasion is determined according to the UE ID and the UE ID is determined according to the paging UE ID, then the UE ID, or the UE paging frame. The time point and / or the time point of the UE paging opportunity can reflect some information of the paging UE ID. With reference to FIG. 4-c, FIG. 4-c is a schematic representation of the instructions for S-TMSI according to an embodiment of the present invention. The paging UE ID is assumed to be a 40-bit S-TMSI. If all of the 2 ^ 40 S-TMSIs are divided into 1024 groups, then the time of the UE paging frame and / or the time of the UE paging opportunity is associated with the group ID, ie the UE ID. Is the group ID to which the UE ID belongs and the UE ID is equal to S-TMSI. In this case, the 10-bit S-TMSI is actually determined according to the time of the paging frame and / or the time of the paging opportunity. The remaining 30-bit S-TMSI may be sent to the UE using signaling or paging messages. The UE detects the paging message at the time of the UE paging frame and / or at the time of the UE paging opportunity determined by the UE paging UE ID, and 30 bits of the paging message ID is 30 of the UE paging UE ID. All you have to do is check if it matches the bit. If the match is successful, the paging message indicates that the UE is paging. Otherwise, the paging message does not indicate that the UE is paging. According to this method, the overhead of the paging message can be reduced, so that the utilization efficiency of system resources is improved and the power consumption consumed by the UE to detect the paging message is reduced. Obviously, methods that reduce paging message overhead can also be used in combination with the paging message sending methods described above to send paging messages more effectively and reduce UE power consumption in a better way. Good.
