TW494690B - Method for performing cell and URA updates in a radio access network - Google Patents

Abstract

A method for performing Cell-Updates or URA-Updates in a mobile communication system is disclosed, whereby a user equipment (UE) sends a Cell-Update message or URA-Update message to an SRNC. The transported Cell-Update message or URA-Update message includes a sequence counter which is incremented each time the UE sends such a message to the SRNC. The SRNC stores the value of the sequence counter for each Cell-Update message or URA-Update message received and acknowledged. If the SRNC receives a Cell-Update message or URA-Update message with a corresponding sequence counter value that is lower than the sequence counter value stored for the previously received Cell-Update message or URA-Update message, then the SRNC ignores the received Cell-Update message or URA-Update message. Also, the SRNC does not store the sequence counter value for the ignored, received Cell-Update message or URA-Update message.

The United States and the United States of America, which were co-filed by cross-reference of related applications, claimed that the priority of this invention came from the reference country patent application δ month number 6 q / 1 6 1, 7 6 8 Literature, proposed on the 27th of July. BACKGROUND OF THE INVENTION The present invention generally relates to the field of mobile communication, and more specifically, to a method for protecting cells and updating a message sequence in a URA (Universal Mobile Communication System Area-Free Proximity Network Area) area. Package Description of related technologies The Universal Mobile Telecommunications System (UM TS) is a version of the so-called third-generation communication system in Europe and is currently being assisted by the European Telecommunications Standards Institute (ETSI) for development. The UMTS network element is called the UMTS Regional Radio Proximity Network (UTRAN). Figure 1 shows a block diagram of the currently developed architecture of the UTRAN. Please refer to FIG. 1, which shows that the UTRAN architecture 10 includes a core network 12. A user equipment (JJE) 19, which is basically a mobile terminal, is used by a user to receive services provided by an operator via the core network 2. The core network 1 2 is integrated into a radio network controller (R N C) 16 a ′, which controls the radio resources and the connections in a group of cells (such as cells 20a-e). Although only one rnc 16a is shown coupled to the core network 12 through an interface, this configuration is for illustrative purposes only. It must understand that 'more than one RNC (such as 16a-c) can be coupled to the core network through the _ interface 1 2. A cell (such as 20a) defines a geographic area, where radio coverage is

Page 5 494690 V. Description of the invention (2) " '' " One-provided by a radio transceiver device at a radio base station. Each such cell is identified by a unique characteristic, which will be broadcast in that individual cell. URA (e.g. 18a) defines a geographical area which consists of one or more cells 7 (e.g. 20a and 20b). Each such URA is identified by a unique characteristic. According to this, a URA can be composed of more than one RNC-controlled cell. A URA with cells controlled by more than one RNC can have an overlap between RNCs (ie, an overlapping Ura). A transmission network (such as the transmission system No. 7) 14 which is coupled to the RNCs 16a-c. The transmission network 14 enables the RNCs to perform the required RNC-to-RNC transmissions. 'When a UE moves between cells controlled by different Rncs in the radio proximity network, it can be maintained. Established connection. For each core network U E connection, the role of an r n C can be dual. One aspect of this RNC is a service rNC (srnc). In this role, it is responsible for the connection with the UE. In other words, the rnc has full control over the connection in the radio proximity network. Accordingly, this r N C is connected to the core network 1 2. The second role of this RNC is that it is a drift RNC (DRNC). In this role, 'the RNC supports the resources of the SRNC radio to connect with the UE', it needs the radio resources controlled by the DRNC in the cell. Basically, the radio proximity network determines the role of an RNC (ie, SRNC or DRNC) when the UE__core network connection is being established. The RNC that normally controls the initial connection established with the UE in the cell is assigned the SRNC role for this UE connection. When the UE moves, the connection

Page 6 494690 V. Description of the invention (3) The radio communication branch established by the cell is maintained, and it is also a cell controlled by other RNCs (such as DRNCs). The former RNC fighters will also be related when the _UE is using shared resources, and experience has reached 1, 4 activities (that is, the transmission of some user data, or a CELL_FACH status). Furthermore, These rn (: roles will also be relevant when Tian UE is using a common source of poverty and is operating in a low activity state (ie no user data transmission, or -CELL_pCH or URA pcH status). In the CELL_FACH & CELL_DCH state, the ue returns its position (cell renewal) based on a cell. In the URA ， state, the UE returns its placement only on the basis of —URA (Xie 5: this. II) Some: The role is related to all the aforementioned states, because the control of UEs in these states is still in the SRNC. Figure 2 shows a state model diagram of a UE. Please refer to Figure 2, which enters after this power supply. Standby mode 4. In this mode, it is time to the UTRAN. When a connection is established, the connection proceeds as the connection mode 2. Thus, there are four states in the connection mode. Each = reverses some kind of activity The degree L shape reflects the characteristics of the CELL-DCH state 7 The purpose is to make a dedicated channel for the UE. The macro can be used to diversify the cells in several cells. The gates, g, '' In this CELL-FACH state 8, no specific report is specified, and the UE continuously monitors The FACH channel belongs to the selected cell. In the winding chain, the ridge basically makes CRACH common in the chain.) When each cell is reselected, the cell location of the ridge updates the network. Road S

Page 7 494690 V. Description of the invention (4) In the CELL-PCH state 6, the UE monitors a call channel (PCH) of a selected cell. On the PCH, the UE enables weekly discontinuous reception (drx) to save power. This method is based on the agreement between the network and the U E when the UE must listen, based on each u E. Meanwhile, at this point, when the UE reselects, the network is updated with the current cell position of the UE. The URA-PCH state 5 is similar to the CELL-PCH state 6. But in URA-PCH state 5, the UE updates the network's position on the UE only after it crosses a ura boundary. A u R A is a cell group. Therefore, in this state, the location of the UE is usually only known at the URA level. 'Figure 3 is a block diagram of the UTRAN architecture shown in Figure 1, which additionally illustrates the role of the RNCs. Referring to FIG. 3, the RNC 116a serves as an SRNC to connect to UE1 19 'UE2 27 and UE3 28. After a continuous cell or URA update, the UE2 27 connection is now delivered through a cell 25 and URA 23a controlled by RNC2 1 6b, which is a drnc for this connection. After successive Cel 1- or URA-updates, the connection of ue 3 28 is now delivered through a cell 26 and URA 23a controlled by RNC3 16c, which acts as a DRNC for this connection. Fig. 4 is a block diagram of the UTRAN architecture shown in Fig. 1, which illustrates how the cell update procedure is performed. As mentioned above, when a UE is in the cell__pch φ or CELL_FACH state, the UE reports a change in its position when it moves from one cell to another (cell update). Please refer to Figure 4, you can see that when moving from cell 1: 2 2 0 b to cell 1: 3 2 0 c, U E1 1 9 performs a cell update. When cell 2 ·· 5 2 5 a When moving to cell 3: 1 2 5 b, · '

Page 8 494690 V. Description of the invention (5) UE 2 2 7 performs a cell update. When moving from cell 3: 3 2 6 a to cell 3: 4 2 6 b, UE 3 2 8 performs a cell update. The cell update is transmitted to the SRNC (ie, RNC1 1 6a) of UE3. The procedure used to transfer the cell updates to the S R N C is shown in the time-series diagram of FIG. 5. Figure 5 shows an RNC-to-RNC signaling procedure, which is used to support cell updates from an RNC (the DRNC), rather than the RNC (the SRNC) when the network connection is established. As shown by routine 30 in Fig. 5, the DRNC sends a cell update request message 32 to the S RNC. In the response, the S R N C sends a cell update response message 34 to the D R N C. A related procedure is performed using a radio air interface, which is also referred to as a cell update procedure, which is illustrated in FIG. As shown in procedure 36 in FIG. 6, the UE sends a cell update request message 37 to the rnc involved. In the response, the RNC sends a cell update response message 39 to the UE. As mentioned before, when the UE in question is in a URA-PCH state (role), the UE only reports a change in its position when it moves from one URa to another. So 'the UE remains in the URA-PCH state even after it has completed the URA update procedure (meaning when the UE crosses a new URA boundary' it constitutes the next contact with the network). In fact, even if the Uj is still basically in the 1 ^ 1 after the URA update process has been completed (: 11), there will be a state transition in the URA update process. Because there will be no state in the URA-PCH state On-chain messages can be sent by the UE. In order to perform the remote UjA update procedure, the UE is switched from the URA — pcH state to the cell — state: In the URA PCH state, the URA update request and response messages are exchanged. § ^ When the UE receives the URA update response message, the UE base

Page 9 494690 V. Description of the invention (6) The book returns to the URA-PCH state. FIG. 7 is a diagram of the radio proximity network architecture of FIG. 1, which illustrates how the URA ^ new procedure is performed. Please refer to the figure. It can be seen that UE1 19 performs a URA update when § * URA1 18a moves to URA2 18b. The UE2 7 will perform a URA update only when a cell 2 5 a already controlled by RNC 2 1 6 b moves to a cell 2 5b controlled by RNC 3 16c, and both cells are in URA5 18e In. The UE 3 2 8 performs a URA update when moving from URA5 18e to URA6 18f. As also shown in Fig. 7, when the U E 3 2 8 performs a U R Δ update procedure, this information is transmitted to the SRNC of the UE3, or RNC1 16a. The procedure used to send the URA update message to the SRNC is shown in Figure 8. Therefore, Figure 8 shows the RNC-to-RNC sending procedure, which is used to support a URA update procedure from an RNC (the DRNC), rather than the RNC (the SRNC) when the network connection is established. . The related procedures performed on this radio air interface are also called URA updates. Figure 9 illustrates the U E to R N C signaling procedure for supporting a U R A update involving the UE. Therefore, referring to the procedure 46 shown in FIG. 9, the involved UE sends a URA update request message 48 to the involved RNC. In the response, the rNC sends a URA update response message to the UE. The existing U MTS technical specifications include a function / procedure called, “reconfiguration.” The main purpose of this function / procedure is from the “ ... transfers control of a specific UE to another node. This reconfiguration procedure includes internal reconfiguration and reconfiguration to other systems (such as Global System for Mobile Communications, or GSM). Therefore, the main purpose of a UMTS-to-UMTS reconfiguration is

Page 10 494690 V. Description of Invention (7) One is to transfer the role of an SRNC from one RNC to another. (For example, if RNC-to-RNC communication is not supported between the RNCs involved, or the transmission t is optimized) μ fetch Two types of reconfiguration functions / procedures are defined. One type of banding involves reconfiguration of the UE. In this example, the role of the SRNC is / changed from one RNC to another. At the same time, the radio interface communication is also handed over from one cell to another. The second form is reconfiguration that does not involve UE. In this example, the role of the SRNC and the transition from one RNC to another does not change the cell that is being used for radio interface communication. The reconfiguration function / procedure is mainly achieved through the core network RNC interface. Preferably, a reconfiguration is initiated by an SRNC. This reconfiguration can be initiated by a cell update or a URA update. However, a reconfiguration can also be initiated by other events. If a reconfiguration is initiated by a cell update or URA update, the response message to the UE is transmitted by the new SRNC. Recent developments Currently, the cell update and URA update procedures in UMTS are not responsible for the possibility of cell update request messages or URA update request messages being received outside of the SRNCn program. In other words, although a certain cell update request message (such as message A) 'may be transmitted by a UE before another cell update request message (such as message b)', the first (A) message may be received after the second ( B) The message is then received by the SRNC. Therefore, due to the foregoing phenomenon, it is not possible to prevent problems during the operation of the cellular network. A. In GSM, the location area update message can be transmitted by a UE to

494690 V. Description of the invention (8) = network (so it is reported on the basis of a "location area", which contains information about the "old" location area. This time, Yuanyuan Network is used to To avoid the inability to maintain the sequence of the transmission message, some errors can be included (also included in the network to send messages). 'The completed one has a Y in the existing UMTS architecture ~ The problem is, move through If the cell network is fast enough, the UE can update in one cell—the UE moves one cell to update. If the two sprints are connected to two ^: = to turn on RNCs', such as cell A and cell B are Controlled by different DRNCs — controlled by the SRNC, cell B is controlled by a DRNC), the delay time of the two = t cell A messages transmitted to the SRNC can be θ _ updated information β this' far second The cell update message can be received at the first cell update message: The SRNC receives it. For similar reasons, the same problem also: If the path is fast enough, the UE can start ⑽A in a cell. New, and soon after that, the URA (and a second URA update in another cell) are updated. If these two cells; = to two different RNCs (such as cell A and cell b line Controlled by different DRNCs, or cell A is controlled by SRNC and cell 6 is controlled by a DRNC), the two URA update messages may have different delay times when they are transmitted to the SRNC. Therefore, the The second URA update message can be received by the SRNC before the first URA update message. Accordingly, the existing ⑽ specifications cannot guarantee that the UE to the s RNC maintains the sequence of cell update messages or URA update messages. .

Furthermore, the existing UMTS specification does not include guarantees for cell renewal or UR A

Page 12 494690

The updated sequence can be maintained in the method received by the SRNC, just as the sequence transmitted by the FE will be in the state after the role of the SRNC is reconfigured to a new RNC. However, as described in detail below, the present invention successfully solves the above problems, as well as other related problems. SUMMARY OF THE INVENTION According to a preferred embodiment of the present invention, a method for performing a cell or URA update in a mobile communication system is provided, whereby a UE sends a cell update message or a URA update message to an SRNC. The transmitted cell update message or URA update message includes a sequence counter which is accumulated once each time such a message is transmitted by the UE to the SRNC. The SRNC stores the value of the sequence counter for each cell update message or URA update message received and notified. If the SRNC receives a cell update message or one of the sequence counter values associated with the URA update message is lower than the sequence counter value of the previously received cell update or URA update message, the SRNC ignores the received cell Update message or URA update message. At the same time, the SRNC does not store the value of the sequence counter value of the received cell update message or U R A update message. Using this method, the SRNC can ensure that the cell update message and the ura update message transmitted by a UE can be processed in sequence. Furthermore, when a reconfiguration procedure is performed, the cell update sequence counter (Cell_Upd_Seq_No) and the URA update sequence counter # (URA_Upd_Seq_No) are transferred from the old SRNC to the new SRNC. If the reconfiguration procedure is initiated by a cell update, the old SRNC and the received cell update sequence counter and the stored URA update sequence are transmitted.

494690 V. Description of the invention (10) Column counter. The new SRNC does not transmit the response to the cell update to the UE until the new SRNC has received a sequence counter from the old SRNC (for both the cell update and the U R A update). If the reconfiguration is initiated by a U R A update, then the old S R N C is transmitted as received. r a updated sequence counter, and the stored cell updated sequence count $. The new SRNC does not send the response to the URA update to the frame until the new SRNC has received a sequence counter from the old SRNC (for both the cell update and the URA update). An important technical advantage of the present invention is that it proposes a method for performing a cell or URA update, whereby an SRNC can guarantee that only the last cell update message or URA update message transmitted by a UE can be sent by the srnc Processed, in those cases, the order of the cell update message or URA update message transmitted by the UE is not maintained by the SRNC when received. Another important technical advantage of the present invention is that it proposes a method for performing a cell or URA update, based on which an SRNC can maintain correct information about the position of ϋΕ, even if a new message from a cell outside the sequence is received from the UE Or UR Α update message. Brief description of the drawings For the method and device of the present invention, a more complete understanding can be obtained through the following detailed descriptions in conjunction with the drawings, where: Figure 1 shows the block of the architecture developed according to UTRAN Figure; Figure 2 shows the state model diagram of the UE; Figure 3 shows the diagram!

Numbering represents similar and related parts in different drawings. Basically, according to a preferred embodiment of the present invention, a method for performing a cell or URA update in a mobile communication system is proposed, whereby a UE sends a cell update message or a URA update message to an SRNC. The transmitted cell update message or URA update message contains a sequence counter

Page 15 494690 V. Description of the invention (12) It is incremented every time the UE sends such a message to the SRNC_ The SRNC stores every received message and notifies the received cell update information, The value of the sequence counter of the URA update message. If the SRNC fails ~ or '~ * ™ k Rural cell update message or URA update message, and a related sequence counter' value, and the value is less than the stored previously received cell update message ^ The URA update message Sequence counter value, the SRNC ignores the received cell update message or URA update message. At the same time, the SRNC # τ stores the value of the sequence counter of the ignored cell update message or URA update message. By this method, the SRNC can guarantee that the cell update message and the URA update message transmitted in white or ~~~ ρ can be processed in sequence. Coincidentally, when a reconfiguration procedure is performed, the cell update sequencer (Cel 1-Upd — Seq — No) and the URA update sequence (quote URA — Upd — Seq — No) are determined by The _SRNC is transferred to the new srnC. If the reconfiguration procedure is initiated by a cell update, the old SRNC is the sequence counter of the cell update received by the cell, and the stored URA line counter. The new SRNC does not send the cell update response to the sequence until the new SRNC receives the sequence count cry from the old SRNC (at the same time, the cell update and URA update). If the reconfiguration is initiated by __ ^ =, the old SRNC transmits the received URA update sequencer and the sequence counter of the stored cell update. The new review does not send this, and the updated response is detailed until the new · has received the sequence count cry by the sales SRNC (due to the technical update, "τ double hitting for the cell update and the URA update). Specifically, FIG. 10 is an exemplary partial diagram of a mobile communication system and system 100.

494690 V. Description of the invention (13) It can be used to implement a preferred embodiment of the present invention. As shown, the system part 100 can be part of a UMTS. However, the present invention is not limited to a particular system or network type or configuration, and may include any appropriate communication system or network 'as long as it is beneficial to a network entity, such as, for example, a radio network. The channel control unit is used to ensure that if the sequence is important, the received transmission or control messages can be processed sequentially. For this example embodiment, the system part 100 includes a core network element 102, a transmission network element 104, and at least one RNC element 106. The core network element 102 can be used by a network manager to provide user access services. The transmission network element 104 may be an SS 7 network, but this invention does not require such a network, and may include any appropriate form of network, as long as it can be delivered between network entities. Sending information (eg between RNCs). For example, the sending network element may send sending information between the RNC 106 shown and other RNCs (not explicitly shown). In any case, for this example embodiment, the network elements shown in the system part 100 can be implemented and operated according to the established UTRAN specifications. The system 100 also includes a UE 116, which, for this specific embodiment, is a mobile radio terminal. The UE 116 communicates with the core network element 102 through a radio air interface. One or more radio base stations (not explicitly shown) located at one or more base stations are associated with the RNC || 1 0 6. As such, the radio base station defines individual cells, such as, for example, cells 1: 2 1 1 2 and 1: 3 1 1 4 related to the RN C 106. One or more cells define one or more U R As, such as URA 1 108 and URA 2 110 related to RNC 106, for example.

Page 17 494690 V. Description of the invention (14) Figure 11 shows a flowchart of an example sending method 2000. For example, it can be used in the system part 100 shown in Figure 10. To implement this preferred embodiment of the invention. In particular, for this specific embodiment, the method 2 is shown when a UE moves from one cell (and / or URA) to another, or when the UE switches from a URA_PCH state to a CELL_PCH state It can be used to perform cell updates and / or URA updates. Therefore, this method 200 can be applied if the UE 1 16 reports its position change, for example, based on a cell (such as a cell update) or a URA based (such as a URA update). So for this specific embodiment, the present invention can ensure an appropriate network entity (such as RNC), even when the network entity receives out-of-sequence cell update or URA update (mobile) message from the UE, Can correctly follow the location of a UE. Please refer to FIGS. 10 and 11. In step 202 of the method, it is assumed that the UE 1 1 6 moves from the cell 1: 2 1 1 2 to the cell 1: 3 1 1 4. The movement is represented by the dotted line and solid dotted arrows from the UE 1 16 to the cells. Please note that the UE 1 16 is also moved from one URA 108 to another 10 as shown in the figure. But 'for the sake of clarity, although this method 2000 can be used for cell update or URA update, the following description is mainly directed to the UE's cell update message to report the movement between cells to an SRNC (such as RNC 1 06). The same or substantially similar method can also be used for a UE to report movement between URAs (or other) to an SRNC 'and use URA to update the message. Returning to step 2 0 2 ', in order to report the movement between cells, the u E 1 1 6 increments a sequence counter to prepare a cell update transmission message, and transmits it to the SRNC. For example, using the created ^! ^^ message format,

Page 18 494690 V. Description of the invention (15) A sequence counter block can be formed like (Cel 丨 ―Upd_SeQ_N〇), and the value in the sequence counter block can be increased by one. Initially, the sequence counter value can be zero. Please note that it must understand that the value of the sequence counter is accumulated once every new update, and can be used as an aid for understanding the present invention. However, the present invention is not intended to be so limited ' but may be included under appropriate conditions, and may be accumulated or decremented by a sequence counter. In another example, the present invention may include a counter, which may use a determined number of increments or decrements (e.g., SRNC and ㈣ as previously known). In step 204 ', the UE 116 transmits a cell update request message through the radio air interface, which contains the latest value of the sequence counter. In this state, the UE has established a connection with the SRNC through the cell 丨: 3 丨 4 or a cell connection. Again, the UE may also send a / RA update request message to the SRNC. In this case, the format of the sequence counter can be configured as (URA-Upd-SeQj〇), and the counter value can be incremented by 1. In step 206, the SRNC (e.g., 106) detects a cell update request message from the UE 116. For this exemplary embodiment, the SRNC decides whether the sequence counter value in the cell update message received by 忒 will be less than the sequence counter & value that was previously received (and stored in the region memory). For example, the previously received and stored sequence counter value may represent a previous movement from the UE ' s from a cell 丨: 1 to 丨 2n2. If the sequence counter value in the received cell update message is less than the previously received (and stored) sequence counter value, in step ^

V. Description of the invention In (16) 2 0 8 the SR NC 1 0 6 starts to perform uncontrolled behavior according to the cell update request message, and does not store the received sequence counter value ° It is worth noting in this step Yes, for design considerations' This month may include a method in which an SRNC looks for a counter value that is not less than the previously received and stored counter value (for example, if the UE is decrementing its sequence counter value ). Otherwise, 'in step 206, if the received sequence counter value is not less than the previously received and stored sequence counter value, then in the dream 2 10,' far SRNC is stored (such as in regional memory ) The value of the latest received magic sequence counter. In step 212, the SRNC 106 transmits a cell update response message to the ^ through cell 1 · 3 1 1 4. In addition, it informs the UE that the corresponding cell update request message has been correctly received. To (contains received-correct sequence counter value). Again, in this example, when § involves movement between Ura, the SRNC can send a 16 update response 5fl message to the UE, which can inform the corresponding update request message has been received (including the Correct sequence counter value). Therefore, the method described in 2000 is used. The "can guarantee that the position of the UE has been correctly tracked 'although it is possible to receive out-of-sequence cell update messages and / or although a preferred embodiment of the method and apparatus of the present invention has been described with reference to the drawings Speaking of the sun and the moon, and interposing in the previous detailed description, it can be understood that the present invention is not limited to the specific embodiment disclosed, but there are many reconfigurations, corrections, and replacements. It would deviate from the spirit of the invention proposed, as defined by the following patent application scope.
