Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to an information configuration method and related equipment. Background Technology

[0002] The message sequence number information pertains to the configuration of the data radio bearer (DRB) between the base station and the terminal. This sequence number includes both Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) sequence numbers. During communication between the terminal and the base station, it is crucial to ensure that the message sequence number information configured on the terminal side matches the one configured on the cell side; otherwise, communication service anomalies may occur.

[0003] In existing technologies, if a terminal needs to perform inter-cell handover, the base station will send the terminal the message sequence number information configured for the cell to which the terminal wants to handover. After receiving the message sequence number information, the terminal needs to configure the message sequence number information locally to ensure consistency with the message sequence number information configured for the cell. After completing the configuration of the message sequence number information, the terminal sends a handover completion message to the base station. If the terminal fails to complete the configuration of the message sequence number information, the terminal will not send the handover completion message to the base station, that is, the terminal reconfiguration of message sequence number information fails. Subsequently, the terminal will initiate a reconstruction with the base station to continue to carry out communication services.

[0004] However, the terminal may re-establish itself in any cell, so the message sequence number information configured on the terminal side may be inconsistent with the message sequence number information configured on the cell side, leading to abnormalities in subsequent communication services. Summary of the Invention

[0005] This application provides an information configuration method and related equipment to ensure that the message sequence number information configured on the terminal side remains consistent with the message sequence number information configured on the cell side after the terminal reconfiguration fails.

[0006] The first aspect of this application provides an information configuration method:

[0007] During communication between the terminal and the base station, the message sequence number information configured by the terminal needs to be consistent with the message sequence number information of the cell to which the terminal is accessing. Therefore, the terminal may need to reconfigure the message sequence number information. However, the terminal may fail to reconfigure the message sequence number information. After the terminal fails to reconfigure the message sequence number information, it will initiate a reconstruction to the base station. If the base station determines that the terminal has failed to reconfigure the message sequence number information and receives a reconstruction request message from the terminal (this message is sent by the terminal to the base station's first cell to indicate that the terminal requests to reconstruct to the first cell), the base station, upon receiving the reconstruction request message, will send a first message sequence number to the terminal to ensure that the message sequence number information configured by the terminal is consistent with that configured by the first cell. After receiving this first message sequence number, the terminal can configure it locally. After the terminal configures the first message sequence number, the base station can receive a first handover completion message or a first reconfiguration completion message from the terminal, indicating that the terminal has successfully configured the first message sequence number information.

[0008] In this embodiment of the application, after the terminal reconfiguration fails and initiates reconstruction to the first cell, the base station will send the first message sequence number information to the terminal, so that the terminal configures the first message sequence number information, thereby ensuring that the first message sequence number information configured by the terminal is consistent with the message sequence number information configured by the first cell, and ensuring the normal operation of communication services.

[0009] In one possible implementation, the failure to reconfigure the terminal's message sequence number information can specifically involve the base station sending a second message sequence number to the terminal. This second message sequence number is used by the terminal to configure second message sequence number information locally. This second message sequence number is consistent with the message sequence number information configured in the second cell. This second message sequence number is used by the terminal to establish a connection with the second cell. The base station includes the aforementioned second cell. After configuring the second message sequence number information, the terminal sends a second handover completion message or a second reconfiguration completion message to the base station. If the base station does not receive a second handover completion message or a second reconfiguration completion message from the terminal within a preset time period, the base station can determine that the terminal's reconfiguration of the message sequence number information has failed.

[0010] In one possible implementation, the base station can send the first message sequence number information to the terminal via a handover command or reconfiguration message.

[0011] In this embodiment of the application, the form in which the base station sends the first message sequence number information to the terminal is specified, which improves the feasibility of the solution.

[0012] In one possible implementation, after the base station sends the first message sequence number information to the terminal, if the base station does not receive the first handover completion message or the first reconfiguration completion message from the terminal within a preset time period, the base station will continue to send the first message sequence number information to the terminal until it receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0013] In this embodiment of the application, the base station can send the first message sequence number information to the terminal multiple times, thereby ensuring that the terminal can successfully configure the first message sequence number information.

[0014] In one possible implementation, the first message sequence number information and the second message sequence number information include message sequence number information of the Packet Data Convergence Protocol (PDCP) and message sequence number information of the Radio Link Control Protocol (RLC).

[0015] A second aspect of this application provides a base station, which includes an input / output device and a processor, wherein the processor is used to execute the method in the first aspect described above.

[0016] A third aspect of this application provides a base station that performs the functions of the base station described in the first aspect. These functions can be implemented in hardware or by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the aforementioned functions.

[0017] A fourth aspect of this application provides a computer-readable storage medium storing a program that, when a computer runs the program, executes the method described in the first aspect. Attached Figure Description

[0027] The embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. As those skilled in the art will understand, with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0028] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] This application provides an information configuration method for determining that a terminal has completed configuration according to the message sequence number information sent by the base station.

[0030] The embodiments of this application can be applied to communication scenarios between base stations and terminals. Please refer to [link / reference]. Figure 1 The coverage area can be divided into different cells, and different cells may be configured with different packet sequence number information. For example, such as Figure 1As shown, cell 1 is configured with message sequence number information 1, cell 2 with message sequence number information 2, cell 3 with message sequence number information 3, cell 4 with message sequence number information 4, cell 5 with message sequence number information 5, and cell 6 with message sequence number information 6. When a terminal accesses cell 6, the terminal needs to configure message sequence number information 6 locally. If the message sequence number information configured locally by the terminal is inconsistent with the message sequence number information configured by the cell, it may cause abnormalities in communication services. Therefore, when the terminal needs to perform inter-cell handover, for example, when the terminal switches from cell 6 to cell 5, it is necessary to ensure that the message sequence number information configured locally by the terminal is consistent with the message sequence number information configured by cell 5.

[0031] Please see Figure 2 The following describes a flow of the information configuration method in an embodiment of this application:

[0032] 201. The base station failed to determine the terminal reconfiguration message sequence number information;

[0033] In some scenarios, the terminal needs to reconfigure the message sequence number information. This message sequence number information belongs to the configuration of the data radio bearer (DRB). If the terminal fails to reconfigure the message sequence number information, the base station can determine that the terminal has failed to reconfigure the message sequence number information.

[0034] 202. The base station receives a reconstruction request message from the terminal;

[0035] After a terminal reconfiguration fails, it will send a reconstruction request message to the base station. This reconstruction request message indicates that the terminal requests to rebuild to the first cell.

[0036] 203. The base station sends a reconstruction message to the terminal;

[0037] After receiving the reconstruction request message from the terminal, the base station sends a reconstruction message to the terminal.

[0038] 204. The terminal sends a reconstruction completion message to the base station;

[0039] After receiving the reconstruction message from the base station, the terminal sends a reconstruction completion message to the base station.

[0040] 205. The base station sends the first message sequence number information to the terminal;

[0041] Since the terminal requests to rebuild to the first cell, and the first cell is configured with the first message sequence number information, the base station sends the first message sequence number information to the terminal. After receiving the first message sequence number information, the terminal configures the first message sequence number information locally. Specifically, the base station can send the first message sequence number information to the terminal through a handover command or a reconfiguration message.

[0042] 206. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0043] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After the configuration is completed, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. The first handover completion message or the first reconfiguration completion message is used to indicate that the terminal has completed the configuration of the first message sequence number information. It should be noted that in step 205, if the base station sends the first message sequence number information to the terminal through a handover command, the terminal sends a first handover completion message to the base station. If the base station sends the first message sequence number information to the terminal through a reconfiguration message, the terminal sends a first reconfiguration completion message to the base station.

[0044] In this embodiment, after the terminal initiates reconstruction to the first cell due to failure to reconfigure the message sequence number information, the base station sends the first message sequence number information configured in the first cell to the terminal, so that the message sequence number information on the terminal side is consistent with the message sequence number information on the cell side, thereby ensuring the normal operation of communication services.

[0045] In another possible implementation, if the terminal does not send a first handover completion message after the base station sends the first message sequence number information to the terminal, the base station can also continue to send the first message sequence number information to the terminal. Please refer to [link to relevant documentation]. Figure 3 The following is a detailed description:

[0046] In this embodiment, steps 301 to 305 are the same as described above. Figure 2 Steps 201 to 205 in the illustrated embodiment are similar and will not be repeated here.

[0047] 306. The base station determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within a preset time period;

[0048] After the base station sends the first message sequence number information to the terminal, it determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within a preset time period.

[0049] 307. The base station sends the first message sequence number information to the terminal;

[0050] If the base station determines that it has not received the first handover completion message from the terminal within the preset time period, in order to ensure that the terminal successfully configures the first message sequence number information locally, the base station continues to send the first message sequence number information to the terminal.

[0051] 308. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0052] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After the configuration is completed, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. The first handover completion message or the first reconfiguration completion message is used to indicate that the terminal has completed the configuration of the first message sequence number information.

[0053] It should be noted that steps 306 and 307 above can be repeated multiple times until the base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0054] In this embodiment of the application, if the base station does not receive the first handover completion message or the first reconfiguration completion message from the terminal, it may continue to send the first message sequence number information to the terminal, thereby increasing the probability that the terminal can successfully configure the first message sequence number information.

[0055] Please see Figure 4 The following describes another process of the information configuration method in this application, taking into account the specific situation where the terminal reconfiguration message sequence number information fails:

[0056] 401. The base station sends a handover command to the terminal;

[0057] When a terminal needs to reconfigure message sequence number information, for example, when the terminal needs to hand over between cells, the base station will send a handover command to the terminal. This handover command will carry the second message sequence number information. For example, the terminal is currently connected to cell 6, but the signal strength provided to the terminal by cell 5 is greater than that provided to the terminal by cell 6. Therefore, the terminal needs to hand over to cell 5, which is the second cell. The base station will send a handover command to the terminal. After receiving the handover command, the terminal will configure the second message sequence number information carried in the handover command locally. This second message sequence number information is used for the terminal to hand over to the second cell, and the second message sequence number information is consistent with the message sequence number information configured in the second cell.

[0058] 402. The base station determines that it has not received a second handover completion message from the terminal within a preset time period;

[0059] After the base station sends the second message sequence number information to the terminal, if the terminal successfully configures the second message sequence number information locally, the terminal will send a second handover completion message to the base station. This second handover completion message indicates that the terminal has completed the configuration of the second message sequence number information. However, if the terminal fails to configure the second message sequence number information, the terminal will not send a second handover completion message to the base station. Alternatively, even if the terminal completes the configuration of the second message sequence number information, it may still fail to send a second handover completion message to the base station. Therefore, if the base station determines that it has not received a second handover completion message from the terminal within a preset time period, the base station cannot determine whether the terminal has completed the configuration of the second message sequence number information, that is, the terminal reconfiguration of the message sequence number information has failed.

[0060] 403. The base station receives a reconstruction request message from the terminal;

[0061] If the terminal does not send a second handover completion message to the base station, the terminal will send a reconstruction request message to the first cell of the base station. This reconstruction request message indicates that the terminal requests to rebuild to the first cell. It should be noted that the first cell and the second cell mentioned above can be the same cell or different cells. No specific limitation is made here.

[0062] 404. The base station sends a reconstruction message to the terminal;

[0063] After receiving the reconstruction request message from the terminal, the base station sends a reconstruction message to the terminal.

[0064] 405. The terminal sends a reconstruction completion message to the base station;

[0065] After receiving the reconstruction message from the base station, the terminal sends a reconstruction completion message to the base station.

[0066] 406. The base station sends the first message sequence number information to the terminal;

[0067] Since the terminal requests to rebuild to the first cell, and the first cell is configured with the first packet sequence number information, the base station sends the first packet sequence number information to the terminal. After receiving the first packet sequence number information, the terminal configures it locally. It should be noted that the first packet sequence number information and the second packet sequence number information can be the same or different; this is not limited here. Specifically, the base station can send the first packet sequence number information to the terminal through a handover command or a reconfiguration message.

[0068] 407. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0069] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After configuration, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. This first handover completion message or first reconfiguration completion message indicates that the terminal has completed the configuration of the first message sequence number information. In step 406, if the base station sends the first message sequence number information to the terminal via a handover command, the terminal sends a first handover completion message to the base station; if the base station sends the first message sequence number information to the terminal via a reconfiguration message, the terminal sends a first reconfiguration completion message to the base station.

[0070] In this embodiment, after the terminal initiates reconstruction to the first cell due to failure to reconfigure the message sequence number information, the base station sends the first message sequence number information configured in the first cell to the terminal, so that the message sequence number information on the terminal side is consistent with the message sequence number information on the cell side, thereby ensuring the normal operation of communication services.

[0071] In another possible implementation, if the terminal does not send a first handover completion message or a first reconfiguration completion message to the base station after the base station sends the first message sequence number information to the terminal, the base station may also continue to send the first message sequence number information to the terminal. Please refer to [link to relevant documentation]. Figure 5 The following is a detailed description:

[0072] In this embodiment, steps 501 to 506 are the same as described above. Figure 5 Steps 401 to 406 in the illustrated embodiment are similar and will not be repeated here.

[0073] 507. The base station determines that it has not received a first handover completion message or a first reconfiguration completion message from the terminal within a preset time period;

[0074] After the base station sends the first message sequence number information to the terminal, it determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within a preset time period.

[0075] 508. The base station sends the first message sequence number information to the terminal;

[0076] If the base station determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within the preset time period, in order to ensure that the terminal successfully configures the first message sequence number information locally, the base station continues to send the first message sequence number information to the terminal.

[0077] 509. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0078] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After the configuration is completed, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. The first handover completion message or the first reconfiguration completion message is used to indicate that the terminal has completed the configuration of the first message sequence number information.

[0079] It should be noted that steps 507 and 508 above can be repeated multiple times until the base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0080] In this embodiment of the application, if the base station does not receive the first handover completion message or the first reconfiguration completion message from the terminal, it may continue to send the first message sequence number information to the terminal, thereby increasing the probability that the terminal can successfully configure the first message sequence number information.

[0081] In another possible implementation, the base station can also send the second message sequence number information to the terminal via a reconfiguration message. (See also...) Figure 6 The following is a detailed description:

[0082] 601. The base station sends a reconfiguration message to the terminal;

[0083] In another scenario, the terminal does not need to perform cell handover, but it needs to update the DRB-related configuration between the terminal and the base station, which includes message sequence number information. The base station can send a second message sequence number to the terminal through a reconfiguration message. This second message sequence number is used for the terminal to establish a connection with the second cell, and the second message sequence number is consistent with the message sequence number information configured in the second cell.

[0084] 602. The base station determines that it has not received a second reconfiguration completion message from the terminal within a preset time period;

[0085] After the base station sends the second message sequence number information to the terminal, if the terminal successfully configures the second message sequence number information locally, the terminal will send a second reconfiguration completion message to the base station. This second reconfiguration completion message indicates that the terminal has completed the configuration of the second message sequence number information. However, if the terminal fails to configure the second message sequence number information, the terminal will not send a second reconfiguration completion message to the base station. Alternatively, even if the terminal completes the configuration of the second message sequence number information, it may still fail to send a second reconfiguration completion message to the base station. Therefore, if the base station determines that it has not received a second reconfiguration completion message from the terminal within a preset time period, the base station cannot determine whether the terminal has completed the configuration of the second message sequence number information, i.e., the reconfiguration of the message sequence number information has failed.

[0086] 603. The base station receives a reconstruction request message from the terminal;

[0087] If the terminal does not send a second handover completion message to the base station, the terminal will send a reconstruction request message to the first cell of the base station. This reconstruction request message indicates that the terminal requests to rebuild to the first cell. It should be noted that the first cell and the second cell mentioned above can be the same cell or different cells. No specific limitation is made here.

[0088] 604. The base station sends a reconstruction message to the terminal;

[0089] After receiving the reconstruction request message from the terminal, the base station sends a reconstruction message to the terminal.

[0090] 605. The terminal sends a reconstruction completion message to the base station;

[0091] After receiving the reconstruction message from the base station, the terminal sends a reconstruction completion message to the base station.

[0092] 606. The base station sends the first message sequence number information to the terminal;

[0093] Since the terminal requests to rebuild to the first cell, and the first cell is configured with the first packet sequence number information, the base station sends the first packet sequence number information to the terminal. After receiving the first packet sequence number information, the terminal configures it locally. It should be noted that the first packet sequence number information and the second packet sequence number information can be the same or different; this is not limited here. Specifically, the base station can send the first packet sequence number information to the terminal through a reconfiguration message or a handover command.

[0094] 607. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0095] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After configuration, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. This first reconfiguration completion message or first handover completion message indicates that the terminal has completed the configuration of the first message sequence number information. In step 606, if the base station sends the first message sequence number information to the terminal via a handover command, the terminal sends a first handover completion message to the base station; if the base station sends the first message sequence number information to the terminal via a reconfiguration message, the terminal sends a first reconfiguration completion message to the base station.

[0096] In this embodiment, after the terminal initiates reconstruction to the first cell due to failure to reconfigure the message sequence number information, the base station sends the first message sequence number information configured in the first cell to the terminal, so that the message sequence number information on the terminal side is consistent with the message sequence number information on the cell side, thereby ensuring the normal operation of communication services.

[0097] In another possible implementation, if the terminal does not send a first reconfiguration completion message or a first handover completion message to the base station after the base station sends the first message sequence number information to the terminal, the base station may also continue to send the first message sequence number information to the terminal. Please refer to [link to relevant documentation]. Figure 7 The following is a detailed description:

[0098] In this embodiment, steps 701 to 706 are the same as those described above. Figure 6 Steps 601 to 606 in the illustrated embodiment are similar and will not be repeated here.

[0099] 707. The base station determines that it has not received the first reconfiguration completion message or the first handover completion message from the terminal within a preset time period;

[0100] After the base station sends the first message sequence number information to the terminal, it determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within a preset time period.

[0101] 708. The base station sends the first message sequence number information to the terminal;

[0102] If the base station determines that it has not received the first handover completion message or the first reconfiguration completion message from the terminal within the preset time period, in order to ensure that the terminal successfully configures the first message sequence number information locally, the base station continues to send the first message sequence number information to the terminal.

[0103] 709. The base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0104] After receiving the first message sequence number information from the base station, the terminal configures the first message sequence number information locally. After the configuration is completed, the terminal sends a first handover completion message or a first reconfiguration completion message to the base station. The first handover completion message or the first reconfiguration completion message is used to indicate that the terminal has completed the configuration of the first message sequence number information.

[0105] It should be noted that steps 707 and 708 above can be repeated multiple times until the base station receives the first handover completion message or the first reconfiguration completion message from the terminal.

[0106] In this embodiment of the application, if the base station does not receive the first handover completion message or the first reconfiguration completion message from the terminal, it may continue to send the first message sequence number information to the terminal, thereby increasing the probability that the terminal can successfully configure the first message sequence number information.

[0107] The base station in the embodiments of this application is described below. Please refer to [link / reference]. Figure 8 The base station 800 in this embodiment includes a determining unit 801, a receiving unit 802, and a transmitting unit 803.

[0108] The determination unit 801 is used to determine that the terminal reconfiguration message sequence number information has failed.

[0109] The receiving unit 802 is used to receive a reconstruction request message from the terminal. The reconstruction request message is sent by the terminal to the first cell. The base station includes the first cell. The reconstruction request message is used to indicate that the terminal requests to rebuild to the first cell. The reconstruction request message is sent by the terminal to the first cell when it fails to determine the reconfiguration message sequence number information.

[0110] The sending unit 803 is used to send the first message sequence number information to the terminal. The first message sequence number information is consistent with the message sequence number information configured in the first cell. The first message sequence number information is used by the terminal to configure the first message sequence number information locally.

[0111] The receiving unit 802 is further configured to receive a first handover completion message or a first reconfiguration completion message from the terminal, wherein the first handover completion message or the first reconfiguration completion message indicates that the terminal has completed configuring the first message sequence number information locally.

[0112] In one possible implementation, based on the aforementioned base station 800, the sending unit 803 is further configured to send a second message sequence number information to the terminal. The second message sequence number information is used by the terminal to configure the second message sequence number information locally. The second message sequence number information is consistent with the message sequence number information configured in the second cell. The second message sequence number information is used by the terminal to establish a connection with the second cell. The base station includes the second cell.

[0113] The determining unit 801 is further configured to determine that no second handover completion message or second reconfiguration completion message has been received from the terminal within a preset time period. The second handover completion message or second reconfiguration completion message is used to indicate that the terminal has completed configuring the second message sequence number information locally.

[0114] In one possible implementation, based on the aforementioned base station 800, the transmitting unit 803 is specifically used to send a handover command or reconfiguration message to the terminal, wherein the handover command or reconfiguration message carries the first message sequence number information.

[0115] In one possible implementation, the first message sequence number information and the second message sequence number information include the message sequence number information of PDCP and the message sequence number information of RLC.

The program stored in the memory 905 can include one or more modules, each module including a series of instruction operations on the server. Furthermore, the central processing unit 901 can be configured to communicate with the memory 905 and execute the series of instruction operations stored in the memory 905 on the base station 900.
