Description

The present invention relates to a base station device , a control method, and a program for transmitting and receiving information related to a base station.

The 3rd Generation Partnership Project (3GPP (registered trademark)) 5th generation (5G) cellular communication standard specifies ANR (Automatic Neighbor cell Relation), which collects information about neighboring cells. ANR allows communication control of terminal devices, including identification of the target cell for handover, by transmitting and receiving information such as the frequency and cell identifier of neighboring cells.

3GPP TS38.412, V17.0.0, April 2022

Here, there are cases where a fault specific to base station equipment manufactured by a specific vendor, such as a software version, occurs. Even in such cases, the base station equipment cannot identify the vendor of the adjacent base station equipment, and as a result of handing over to a different base station, the same fault may occur in the base station equipment at the handover destination. In this way, there is an issue that communication control of the terminal device may not be performed efficiently because the vendor of the base station equipment cannot be identified.

The present invention provides a technology that enables communication control of a terminal device based on information about the vendors of adjacent base station devices.

A base station device according to one aspect of the present invention comprises:
A transmission means for transmitting a setup request message regarding an inter-base station interface or cooperative communication between base stations to another base station device;
a first receiving means for receiving a setup response message including vendor information capable of identifying a vendor of the other base station device from the other base station device;
a first acquisition means for acquiring information about a vendor in which a failure has occurred from an external device;
a communication control means for generating neighboring cell information for a base station other than the vendor in which the failure occurred, which is acquired by the first acquisition means, among the other base stations that have transmitted the setup response message received by the first receiving means , and for controlling communication of a terminal device connected to the base station device based on the neighboring cell information;
The present invention is characterized by comprising:

The present invention provides a technology that enables communication control of a terminal device based on information about the vendors of adjacent base station devices.

The following embodiments are described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be combined in any combination. In addition, the same reference numbers are used for the same or similar configurations, and duplicate descriptions are omitted.

(Configuration of wireless communication system)
1 shows an example of the configuration of a wireless communication system according to this embodiment. The wireless communication system 1 is a cellular communication system configured in compliance with a cellular communication standard such as the 5th generation (5G) standard or the 4th generation (4G) standard of the 3rd Generation Partnership Project (3GPP (registered trademark)). The wireless communication system includes base station devices 10A, 10B, and 10C (sometimes referred to as base station devices 10 without distinction) and a terminal device 20.

In FIG. 1, only three base station devices and one terminal device are shown for the sake of simplicity, but it is possible to have two or less base station devices, four or more base station devices, and multiple terminal devices. The base station device 10 forms one or more cells and provides communication to the connected terminal device 20. The terminal device 20 can connect to the cell formed by the base station device 10. In the example of FIG. 1, the terminal device 20 is connected to the base station device 10A. The vendor of the base station devices 10A and 10B is Vendor A, and the vendor of the base station device 10C is Vendor B. In this embodiment, the vendor of the base station device 10 is described as the developer and manufacturer of the base station device, but it may also be the supplier of the control software for the base station device or the distributor of the base station device. In addition, for the base station device 10A, the base station devices 10B and 10C are base station devices of adjacent cells, and can be selected as targets when executing communication control such as handover and dual connectivity for the terminal device 20.

An example of a mobility control scenario will be described with reference to FIG. 2. As described above, the terminal device 20 is connected to the base station device 10A. The base station device 10A decides to hand over the terminal device 20 to the base station device 10 of the neighboring cell in response to a report of the received signal strength (RSRP) and received signal quality (RSRQ) from the neighboring cell base station transmitted from the terminal device 20. Such a handover decision is made based on neighboring cell information generated in advance by the ANR function. As shown in FIG. 2, the neighboring cell information is stored in the base station device 10A as a list in which the frequency, cell identifier, and vendor for each cell are associated, for example. In this embodiment, the cell identifier is described as a PCI (Physical-layer Cell Identifier).

Here, for example, as shown in the following two examples, the terminal device 20 may benefit from handing over to a base station device 10 manufactured by a specific vendor.

The first example is a case where, for example, the base station device 10 of vendor A is equipped with advanced functions or functions desired to be used by the terminal device 20, while the base station device 10 of vendor B is not equipped with these functions. In such a case, the base station device 10A hands over the terminal device 20 to the base station device 10B of vendor A which is equipped with the advanced functions, thereby enabling the terminal device 20 to continue to use the functions desired to be used.

The second example is a case where a vendor-specific failure occurs in the base station device 10 of vendor A. For example, a malfunction may occur in the base station device of vendor A due to a bug in a specific software version. In one example, the base station device of vendor A may malfunction when it receives a handover message due to an upgrade of the control software. Here, if the base station device 10 does not have neighboring cell information that can identify the vendor of the base station of the neighboring cell, the base station device 10A may cause the base station device 10B to operate abnormally by instructing the terminal device 20 to perform a handover to the base station device 10B of vendor A. For this reason, the base station device 10A can prevent the base station device 10B from operating abnormally by executing communication control of the terminal device 20 so as not to send a handover message to the base station device 10B of vendor A.

The following describes the configuration by which the base station device 10 performs communication control of the terminal device 20 based on vendor information related to the vendor of the base station device of the adjacent cell.

(Hardware configuration)
The hardware configuration of the base station device 10 and the terminal device 20 according to this embodiment will be described with reference to FIG.

The base station device 10 and the terminal device 20 are configured to include a processor 301, a ROM 302, a RAM 303, a storage device 304, and a communication circuit 305. Each of the components 301 to 305 is connected to each other via a bus 306 so that they can communicate with each other.

The processor 301 is a computer including one or more processing circuits such as a general-purpose CPU (Central Processing Unit) or an ASIC (Application Specific Integrated Circuit), and functions as a control unit that controls the entire base station device 10 and the terminal device 20 by reading and executing a program stored in the ROM 302 or the storage device 304. The processor 301 can acquire vendor information about the vendor of the base station device 10 stored in the ROM 302 or the storage device 304. The ROM 302 is a read-only memory that stores information such as programs executed by the base station device 10 and the terminal device 20 and various parameters. The RAM 303 functions as a workspace when the processor 301 executes a program, and is a random access memory that stores temporary information. The storage device 304 is, for example, a removable external storage device. The communication circuit 305 is, for example, a circuit for wireless communication of LTE or 5G. In addition, the base station device 10 may include a circuit for wired communication used for communication between base stations, as an example. Although one communication circuit 305 is illustrated in FIG. 3, the base station device 10 and the terminal device 20 may have multiple communication circuits. For example, the base station device 10 and the terminal device 20 may have wireless communication circuits for LTE (4G), 5G, and its successor standards, and a common antenna for these circuits. The base station device 10 and the terminal device may have separate antennas suitable for each standard. The base station device 10 may also have a wired communication circuit used when communicating with other base station devices or nodes of the core network. The terminal device 20 may also have a communication circuit conforming to a wireless communication standard other than the cellular communication standard, such as a wireless local area network (LAN) or Bluetooth (registered trademark). The base station device 10 and the terminal device 20 may have separate communication circuits 305 for each of the multiple available frequency bands, or may have a common communication circuit 305 for at least some of the frequency bands.

The functional configuration of the base station device 10 will be described with reference to FIG. 4. The base station device 10 functions as a vendor information transmission unit 401, a vendor information reception unit 402, a neighboring cell information generation unit 403, and a communication control unit 404 by the processor 301 reading and executing programs stored in the ROM 302 and the storage device 304. Note that FIG. 4 illustrates only the functions related to this embodiment, and other functions that the base station may have are omitted from the illustration.

The vendor information transmission unit 401 provides vendor information capable of identifying the vendor of the base station device 10 to other base station devices 10 or terminal devices 20. For example, the vendor information transmission unit 401 includes vendor information in a setup response message, which is a response to a setup request message between the base station device 10 and other base station devices 10 or a setup request message for cooperative communication, and transmits the setup response message to other base station devices. The setup response message includes at least one of an X2 Setup Response, an Xn Setup Response, and an Endc Setup Response message.

The vendor information transmission unit 401 also transmits the vendor information of the base station device 10 using a broadcast message such as SIB1 (System Information Block type 1). That is, the vendor information transmission unit 401 transmits the vendor information using any one of the transmission methods of unicast, multicast, and broadcast. The vendor information transmission unit 401 may also transmit the vendor information using a wireless signal, or may transmit the vendor information via wired communication. Note that the vendor information transmission unit 401 only needs to transmit the vendor information using at least one of the above-mentioned methods, and does not need to transmit the vendor information using all of the above-mentioned methods.

The vendor information receiving unit 402 receives vendor information capable of identifying the vendor of the base station device 10 from another base station device 10 or a terminal device 20. Specifically, the vendor information receiving unit 402 can acquire vendor information from another base station device 10 via X2 Setup Response, Xn Setup Response, and Endc Setup Response messages via the base station interface. Also, the vendor information of another base station device 10 can be acquired from the terminal device 20 via a measurement report message. In another example, vendor information can be acquired from another base station device 10 via an SIB1 message via an LTE, NR link.

The neighboring cell information generating unit 403 generates neighboring cell information based on vendor information of other base station devices 10 acquired from other base station devices 10 or terminal devices 20. In one example, the neighboring cell information generating unit 403 transmits the created neighboring cell information to the terminal device 20 connected to the base station device 10. The neighboring cell information according to this embodiment includes information (vendor information) capable of identifying the vendor of the base station device 10. For example, together with the vendor information acquired by the vendor information receiving unit 402, vendor information associated with the frequency of the neighboring cell and a cell identifier (ID) is treated as the neighboring cell information.

The communication control unit 404 performs mobility control (communication control) of the terminal device 20, such as E-UTRAN (Evolved Universal Terrestrial Radio Access) New Radio Dual Connectivity (ENDC), handover, and load balancing, based on the vendor information included in the neighboring cell information.

Figure 5 shows an example of the software configuration of the terminal device 20. The processor 301 of the terminal device 20 reads and executes programs stored in the ROM 302 and the storage device 304, thereby functioning as a vendor information receiving unit 501 and a vendor information transmitting unit 502.

The vendor information receiving unit 501 acquires vendor information capable of identifying the vendor of the base station device 10 from the base station device 10. In this embodiment, the terminal device 20 acquires the vendor information of the base station device 10B by receiving a radio signal transmitted from another base station device 10B while connected to the base station device 10A. In one example, the vendor information is acquired by receiving a broadcast SIB1 message. In order to detect the SIB1 of the neighboring cell base station, the terminal device 20 transitions to a discontinuous reception (DRX) mode and measures the radio signal. The process of acquiring the SIB1 message will be described later with reference to FIG. 7.

The vendor information transmission unit 502 transmits vendor information of other base station devices 10 to the base station device 10. In this embodiment, the terminal device 20 transmits a measurement report message including the vendor information of the base station device 10B acquired by the vendor information reception unit 501 to the base station device 10A to which the terminal device 20 is connected.

(Processing example 1)
Next, an example of a process executed in the wireless communication system 1 according to the present embodiment will be described with reference to Fig. 6. In one example, the process shown in Fig. 6 is executed when a base station device 10A is added to the wireless communication system 1.

In the process of FIG. 6, information regarding the vendor of the base station device 10 is included in the control message transmitted and received between the base station devices 10. As described above, control messages that include vendor information include the Xn/X2 setup response message and the Endc setup response message. In another example, the X2 and Xn setup messages, which are setup messages between base stations, and the Endc setup message, which is a setup message for cooperative communication such as dual connectivity, include vendor information.

The base station device 10A transmits an Xn Setup Request or X2 Setup Request message, which is a setup request message for the Xn or X2 interface, to the base station device 10B (S601). In one example, an Endc Setup Request, which is a setup request message for cooperative communication, may be transmitted in S601.

Next, in response to the setup request message received in S601, base station device 10B transmits a setup response message to base station device 10A (S602). Specifically, in response to the setup request message received by base station device 10B in S601, it transmits an Xn Setup Response, X2 Setup Response, or Endc Setup Response message to base station device 10A. Here, the setup response message includes vendor information. Therefore, by analyzing the setup response message received in S602, base station device 10A can obtain vendor information that can identify the vendor of base station device 10B.

Then, as described above with reference to the neighboring cell information generating unit 403, the base station device 10A generates neighboring cell information based on the vendor information included in the setup response message received in S602 (S603).

Then, the base station device 10A executes communication control of the terminal device 20 based on the generated neighboring cell information (S604). Below, an example of controlling communication of the terminal device 20 using neighboring cell information created based on vendor information will be described.

In a first example, the base station device 10 transmits neighboring cell information including vendor information to the terminal device 20. In this case, the neighboring cell information is associated with the cell ID of the neighboring cell and the vendor information of the base station device forming the neighboring cell. The terminal device 20 acquires information indicating whether the specified function is supported for each vendor at any timing from an external device in order to use a specified function according to the application to be executed and the model. If a communication carrier operates a database of vendors and functions supported by the vendors, the terminal device 20 can acquire information identifying the vendors that support the specified function from the database. In another example, the external device may be a plurality of devices operated by each vendor, and a device that provides information indicating a list of functions supported by the vendor. As a result, for example, the terminal device 20 can receive radio signals transmitted only from the base station device 10 of the vendor that supports the specified function by acquiring information about the vendors that support the specified function that the terminal device 20 desires to use from the external device. This allows the terminal device 20 to transmit to the base station device 10 a measurement report on a radio signal transmitted by a base station device 10 that supports a predetermined function that the terminal device 20 desires to use, and to hand over to a base station device 10 that supports the predetermined function. The terminal device 20 may or may not receive a radio signal transmitted from a base station device 10 of a vendor that does not support the predetermined function. For example, the terminal device 20 receives a radio signal transmitted from a base station device 10 regardless of whether the base station device 10 supports the predetermined function, and transmits a measurement report on the base station device 10 of a vendor that supports the predetermined function when the reception results of both the radio signal transmitted from the base station device 10 of a vendor that supports the predetermined function and the radio signal transmitted from the base station device 10 of a vendor that does not support the predetermined function satisfy the handover conditions. On the other hand, when only the reception results of the radio signal transmitted from the base station device 10 of a vendor that does not support the predetermined function satisfy the handover conditions, the terminal device 20 transmits a measurement report on the base station device 10 of a vendor that supports the predetermined function. This allows handover to be preferentially performed to the base station device 10 of a vendor that supports the predetermined function. Similarly, the terminal device 20 may obtain information about the vendor of the base station device 10 in which the malfunction is occurring from an external device, and may hand over only to a base station device 10 in which the malfunction is not occurring, or may preferentially hand over to a base station device 10 in which the malfunction is not occurring. In this case, the terminal device 20 accesses an external device operated by a telecommunications carrier or a vendor and provides information about the vendor and malfunctions occurring in the base station device 10 of the vendor, and suppresses the transmission of measurement reports about radio signals transmitted from the base station device 10 in which the malfunction is occurring, thereby preventing handover to the base station device 10 in which the malfunction is occurring. The base station device 10A may additionally inquire of the base station device 10 that is a candidate for handover or dual connectivity whether a predetermined function is supported.

In a second example, the neighboring cell information generation unit 403 generates neighboring cell information based on but not including the vendor information, and the communication control unit 404 transmits the generated neighboring cell information to the terminal device 20. For example, when generating neighboring cell information in which the frequency and cell ID of the base station device 10 of the neighboring cell are associated, it is determined based on the vendor information whether or not to include the frequency and cell ID of a specific base station device 10 in the neighboring cell information.

For example, the base station device 10A determines whether the base station device 10 supports a specific function that the terminal device 20 wishes to use from the vendor information of the base station device 10 of the neighboring cell, and transmits the neighboring cell information to the terminal device 20 after excluding the base station device 10 that does not support the specific function from the neighboring cell information. The terminal device 20 creates a measurement report for the base station device 10 included in the received neighboring cell information, and does not transmit a measurement report to the connected base station device 10 for the base station device 10 that is not included in the neighboring cell information. As a result, the terminal device 20 measures only the radio signals transmitted from the base station device 10 that supports the specific function that the terminal device 20 wishes to use, and it is possible to control the terminal device 20 not to hand over to a base station device 10 that does not support the specific function. In such a case, the base station device 10 may receive information on the specific function that the terminal device 20 wishes to use from the terminal device 20.

Also, for example, the base station device 10A excludes a base station device 10 in which a fault such as a malfunction has occurred from the vendor information of the base station devices 10 of the neighboring cells from the neighboring cell information and transmits the neighboring cell information to the terminal device 20. This makes it possible to control the terminal device 20 so that it does not hand over to the base station device 10 in which a fault has occurred. In such a case, the base station device 10 may obtain information on the vendor in which the fault has occurred from an external device.

In a third example, the communication control unit 404 measures radio signals such as reference signals as candidates for handover destinations, and when generating a list (whitelist) of base station devices 10 for which a measurement report is to be created, determines whether or not to include a specific base station device 10 in the whitelist based on vendor information, and transmits the generated whitelist to the terminal device 20. The whitelist is used from the base station device 10 to instruct the terminal device 20 to measure radio signals transmitted from a specific base station device 10 as candidates for handover destinations, so that handover to a base station device 10 not included in the whitelist can be prevented.

In a fourth example, the communication control unit 404 creates a list (blacklist) of candidates for handover destinations for which measurement reports are not to be generated, based on vendor information. In such a case, the communication control unit 404 determines whether or not to include a specific base station device 10 in the blacklist based on the vendor information, and transmits the generated blacklist to the terminal device 20. Since the terminal device 20 does not generate measurement reports for base station devices 10 included in the blacklist, the blacklist is used to instruct not to measure radio signals transmitted from specific base station devices 10 as candidates for handover destinations.

In the fifth example, when the base station device 10A receives from the terminal device 20 a measurement report including a measurement result of a radio signal transmitted by the base station device 10 of the neighboring cell, the base station device 10A uses the neighboring cell information when making a handover decision. For example, the terminal device 20 creates a measurement report on the radio signal transmitted from the neighboring cell base station regardless of the vendor of the neighboring cell base station. Here, since the measurement report includes a measurement identifier (MeasId) and a physical cell identifier (PCI), the base station device 10A can identify the cell measured by the terminal device 20 based on the combination of MeasId and PCI, and can identify the base station device corresponding to the identified cell. Therefore, when determining the handover destination based on the measurement report, the base station device 10 that has received the measurement report determines whether or not to perform a handover based on the vendor information corresponding to the base station device 10 indicated in the measurement report. The decision of whether or not to perform a handover may be based on the function that the terminal device 20 wishes to use or the presence or absence of an operational malfunction, as in the above example. In such a case, the neighboring cell information does not need to be transmitted to the terminal device 20. This allows the base station device 10, which receives a measurement report sent by the terminal device 20, to control the handover of the terminal device 20 based on the vendor information.

As described above, the base station device according to this processing example transmits information related to the vendor of the base station device when setting up the base station-to-base station interface or the cooperative communication between base stations. This makes it possible to generate neighboring cell information based on the vendor information, enabling communication control of the terminal device based on the vendor of the base station device. Note that in this embodiment, the vendor information is only included in the setup application message. However, the vendor information of the base station device 10A may also be included in the setup request message transmitted in S601. This allows the base station device 10B that receives the setup request message to also generate neighboring cell information based on information related to the vendor of the base station device 10A.

(Processing example 2)
Next, an example of a process executed in the wireless communication system 1 will be described with reference to FIG.

In the process of FIG. 7, information about the vendor of the base station device 10 is included in the control message transmitted and received between the base station device 10 and the terminal device 20.

The terminal device 20 is connected to the base station device 10A and is in an RRC-Connected state (S701). In addition, the base station devices 10A and 10B broadcast a radio signal including a reference signal in a specific resource (S702). Here, the reference signal is measured by the terminal device 20 and used to create a measurement report (S703). Here, the measurement report includes the PCI (Physical-layer Cell Identifier) of the base station device 10B included in the radio signal from the base station device 10B, which is the base station of the adjacent cell, and at least one of the RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) of the reference signal.

Then, the terminal device 20 transmits the measurement report created in S703 to the connected base station device 10A (S704). As described above, the measurement report includes the PCI and RSRP/RSRQ of the detected base station device 10B. Therefore, the base station device 10A can detect that it is unable to identify the vendor of the base station device 10B corresponding to the PCI based on the measurement report by determining whether or not vendor information is included in the neighboring cell information of the base station device 10B. If the base station device 10A already has vendor information of the base station device 10B from which the PCI was obtained, the processing from S705 onwards may be omitted.

If the base station device 10A cannot identify the vendor of the base station device 10B, it transmits an RRC Reconfiguration message in the case of 5G or an RRC Connection Reconfiguration message in the case of 4G to the terminal device 20, and performs RRC settings for ANR to obtain vendor information of the base station device 10B (S705). The RRC Reconfiguration message or the RRC Connection Reconfiguration message may include resource location information that can identify at least one of the frequency and timing at which the SIB1 (System Information Block type 1) message is transmitted from the base station device 10B. This allows the terminal device 20 to determine the timing at which it wakes up when it wakes up intermittently to receive the SIB1 message, as described in S707 and subsequent steps. Furthermore, when the terminal device 20 receives an RRC Reconfiguration message or an RRC Connection Reconfiguration message indicating the resource from which the SIB1 message of the base station device 10B is transmitted, the terminal device 20 transitions to a discontinuous reception (DRX) mode as described later in S709. For this reason, the RRC Reconfiguration message or the RRC Connection Reconfiguration message indicating the resource from which the SIB1 message of the base station device 10B is transmitted also functions as a message indicating the transition of the state of the terminal device 20. In addition, since the RRC Reconfiguration message or the RRC Connection Reconfiguration message transmitted in S705 also functions as a message instructing measurement of the SIB1 message transmitted by the base station device 10B, these messages may include the PCI as an identifier of the base station device 10B.

Then, in response to the message received in S705, the terminal device 20 transmits an RRC Reconfiguration Complete message in the case of 5G, or an RRC Connection Reconfiguration Complete message in the case of 4G, to the base station device 10A (S706).

Then, the terminal device 20 transitions to a DRX (Discontinuous Reception) mode (S707), sleeps for a predetermined period, and then starts the receiving circuit of the communication circuit 305 at the timing when SIB1 is transmitted. Here, since the SIB1 message transmitted by the base station device 10B is a signal that can be received without connecting to the base station device 10B, the terminal device 20 can obtain the vendor information of the base station device 10B contained in the SIB1 message by waking up the receiving circuit at the timing when the SIB1 message is transmitted and obtaining the SIB1 message. In addition, in the case of a 4G system, the SIB1 message includes an EGCI (E-UTRAN Cell Global ID) including the ECI (E-UTRAN Cell ID) and PLMN (Public Land Mobile Network) of the base station device 10B. In addition, in the case of a 5G system, the SIB1 message includes an NCGI (NR Cell Global ID) including the NCI (NR Cell ID) and PLMN of the base station device 10B.

When the terminal device 20 receives the SIB1 message transmitted from the base station device 10B, it acquires the vendor information contained in the SIB1 message, creates a measurement report message (S709), and transmits the measurement report message to the base station device 10A (S710). The measurement report message includes the ECGI or NCGI of the base station device 10B acquired by the terminal device 20 in S708, and the vendor information of the base station device 10B. This allows the base station device 10A, which receives the measurement report message, to acquire the vendor information of the base station device 10B.

The invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the invention.
