Description

Technical Field

[0001] The present application relates to the field of wireless communication networks, and in particular to a method and device for updating the configuration of a base station service cell, and a storage medium. Background Art

[0002] In the 5G network, when a user's mobile phone moves from an area managed by one base station (service cell) to an area managed by another base station (neighboring cell) during a call, it is necessary to ensure that the new base station has correctly configured the neighboring cell configuration parameters, that is, the neighboring cell configuration, so that the mobile phone can seamlessly switch to the new base station to ensure the continuity of the call and data connection. If the neighboring cell configuration is not updated in time, the user's call may be stuck or interrupted. Therefore, the accuracy and real-time nature of the neighboring cell configuration update are particularly important.

[0003] In the prior art, there are two main ways to update the neighboring cell configuration. One way is manual update. The technician needs to manually check and update the neighboring cell configuration of each base station. This is very cumbersome and error-prone when there are a large number of base stations, and it is inefficient. Another way is automatic update of the base station, which exchanges neighboring cell information between adjacent base stations through XN (X2 / Xn interface) messages, or uses the ANR (Automatic Neighbour Relation) function to update the neighboring cell configuration based on the CGI (Cell Global Identity) information reported by the terminal. Obviously, the XN message update depends on the stable XN connection of the base station. Once the XN connection is unstable or the XN connection does not exist, the update cannot be achieved. Similarly, the ANR function update depends on the terminal's support for the CGI information reporting capability. If the terminal does not support CGI information reporting, it cannot be updated.

[0004] In view of the problem that the configuration update stability of the base station service cell is low in the related technology, no effective solution has been proposed yet. Summary of the invention

[0053] In this embodiment, a method for updating the configuration of a base station service cell is provided, which is applied to the above-mentioned computer terminal. Multiple base stations deployed in the target area are respectively connected to the core network, each of the base stations corresponds to one or more service cells, and the multiple service cells corresponding to the multiple base stations cover the communication of terminal devices in the target area. Each of the service cells stores the configuration parameters of other service cells having a neighboring relationship. The method is applied to the core network. Figure 2 is a flow chart of a method for updating the configuration of a serving cell core network according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0054] Step S202, receiving target update information carrying target configuration parameters sent by a target base station among the multiple base stations, wherein the target update information is used to indicate that the configuration parameters of the target serving cell in one or more reference serving cells corresponding to the target base station are currently changed to the target configuration parameters;

[0055] Step S204, in response to the target update information, locating other candidate serving cells that have the neighboring relationship with the target serving cell from the one or more serving cells corresponding to the target area;

[0056] Step S206, generating target synchronization information carrying the target configuration parameters;

[0057] Step S208, sending the target synchronization information to a reference base station corresponding to the candidate service cell, wherein the target synchronization information is used to instruct the reference base station to update the configuration parameters of the target service cell stored in the candidate service cell to the target configuration parameters, and the target configuration parameters are used to provide communication switching when the terminal device in the candidate service cell moves to the target service cell.

[0058] The above technical solution solves the problem of low stability of configuration update of base station service cells in related technologies, and achieves the technical effect of improving the stability of configuration update of base station service cells.

[0059] Optionally, in this embodiment, multiple base stations are deployed in the target area, each base station is connected to the core network and is uniformly managed by the core network, each base station manages one or more service cells, and stores configuration parameters of the service cells it manages and the service cells that have an adjacent relationship with the service cells it manages, wherein the configuration parameters can provide communication switching when the terminal device moves from one service cell to an adjacent service cell, including the physical cell identity (Physical Cell Identity, PCI) of the service cell, the global cell identity (Global Cell Identity), the tracking area code (Tracking Area Code, TAC), the public land mobile network (Public Land Mobile Network, PLMN) identity, the synchronization signal block (Synchronization Signal Block, SSB) frequency, etc.; in the service cell corresponding to any base station, the user terminal device can transmit signals through the base station, and the service cells managed by multiple base stations cover the communications of all terminal devices in the target area.

[0060] Optionally, in this embodiment, Figure 3 is a structural diagram of a wireless communication network in a target area according to an embodiment of the present application, such as Figure 3 As shown, for two adjacent base stations (base station A and base station B) in the target area, base station A manages service cell A1 and service cell A2, and terminal equipment in the service cell area of ​​base station A needs to transmit signals through base station A, and base station A stores the configuration parameters of service cell B1 and service cell B2 that have an adjacent relationship with service cell A1 and service cell A2, which are PB1 and PB2 respectively; base station B manages service cell B1 and service cell B2, and terminal equipment in the service cell area of ​​base station B needs to transmit signals through base station B, and base station B stores the configuration parameters of service cell A1 and service cell A2 that have an adjacent relationship with service cell B1 and service cell B2, which are PA1 and PA2 respectively. In this application, if service cell B1 configures service cell A1 as a neighboring cell, it is said that there is an adjacent relationship between service cell B1 and service cell A1, and the configuration of service cell A1 is stored in service cell B1. Therefore, when the configuration parameters of service cell A1 change, the latest configuration parameters after the change need to be synchronized to service cell B1. Otherwise, when the mobile terminal moves between the serving cell B1 and the serving cell A1, the communication will be affected or even interrupted due to the asynchronization of the configuration parameters of the serving cell A1.

[0061] Optionally, in this embodiment, the target update information may be but is not limited to a RANCONFIGURATION UPDATE message (RAN' message for short) carrying target configuration parameters. This information is an NG interface information sent by the target base station to the core network, and may carry the target configuration parameters of the target service cell in the reference service cell (all service cells) managed by the target base station, wherein the target service cell may be a service cell whose configuration parameters have been changed among all service cells managed by all target base stations, and the target configuration parameters may be the changed configuration parameters.

[0062] Optionally, in this embodiment, it is assumed that the configuration parameters of the service cell A1 managed by the base station A are changed from PA1 to PA1', that is, the target base station is the base station A, the target service cell is the service cell A1, and the target configuration parameters are PA1'. Figure 4 is a target configuration parameter message structure diagram according to an embodiment of the present application, such as Figure 4 As shown, neighbourinformation-NR represents an information element, which encapsulates the target configuration parameter PA1' of the serving cell A1, including the changed configuration parameters PLMN, TAC, SSB frequency, etc. of the serving cell A1. Figure 5 1 is a message structure diagram carrying target configuration parameters sent by a base station to a core network according to an embodiment of the present application. After PA1' is embedded in the RAN CONFIGURATION UPDATE message, target update information (RAN') is obtained. Figure 5 As shown, the message structure of the target update information RAN' includes the id-neighbour-info-NR message, which is the information element of the newly added serving cell A1 target configuration parameter PA1'.

[0063] Optionally, in this embodiment, after receiving the RAN' message sent by base station A, the core network may respond to the message in the following manner, but is not limited to: Figure 3As shown, the core network locates the candidate service cells that have an adjacent relationship with the service cell A1 from the multiple service cells (service cell A1, service cell A2, service cell B1, service cell B2) managed in the target area according to the information of the target configuration parameters in RAN', that is, service cell A2 and service cell B1, and determines that the reference base stations corresponding to the candidate service cells are base station A and base station B respectively; then generates target synchronization information carrying PA1', wherein the target synchronization information is an AMF CONFIGURATION UPDATE message (abbreviated as AMF') carrying the target configuration parameters, which is an NG interface information sent by the core network to the reference base station; then sends AMF' to base station A and base station B, and AMF' can instruct base station A and base station B to update the stored neighboring cell configuration parameters corresponding to the service cell A2 and the service cell B1 to the target configuration parameters, that is, the neighboring cell configuration parameters of the service cell A2 stored in base station A are updated from PA1 to PA1', and the neighboring cell configuration parameters of the service cell B1 stored in base station B are updated from PA1 to PA1', thereby completing the update of the neighboring cell configuration.

[0064] In an exemplary embodiment, other candidate service cells that have an adjacent relationship with the target service cell can be located from the service cell in the following manner, but is not limited to: obtaining the service cell and the adjacent cell set that have a corresponding relationship, wherein the adjacent service cell set corresponding to each of the service cells includes one or more adjacent service cells that have the adjacent relationship with the service cell; matching the target adjacent cell set corresponding to the target service cell from the service cell and the adjacent cell set that have a corresponding relationship; and determining one or more of the adjacent service cells included in the target adjacent cell set as the candidate service cells.

[0065] Optionally, in the present embodiment, each base station also stores a set of service cells that it manages and service cells that are adjacent to the service cells it manages. For example, the sets A1{A2, B1} and A2{A1, B2} stored in base station A represent that the adjacent cells of service cell A1 are A2 and B1, and the adjacent cells of service cell A2 are A1 and B2, respectively. If the target service cell is A1, and it is necessary to locate other cells that are adjacent to A1 from the service cells in the target area, the target service cell A1 can be matched to the set A1{A2, B1} according to the set stored in base station A, and A2 and B1 included in the set can be determined as candidate service cells.

[0066] In an exemplary embodiment, a service cell and a set of neighboring cells having a corresponding relationship can be constructed in the following manner, but is not limited to: receiving neighboring relationship information uploaded by each of the multiple base stations deployed in the target area to obtain multiple neighboring relationship information, wherein each of the neighboring relationship information is used to indicate one or more neighboring service cells of each of the multiple service cells of the corresponding base station; and constructing the service cell and the set of neighboring cells having a corresponding relationship according to the multiple neighboring relationship information.

[0067] Optionally, in this embodiment, if Figure 3 As shown, taking base station A as an example, the cells that have an adjacent relationship with the service cell A1 managed by it are service cell A2 and service cell B1, and the cells that have an adjacent relationship with the service cell A2 managed by it are service cell A1 and service cell B2. Then, based on these adjacent relationship information, a set of service cells and adjacent cells with corresponding relationships are constructed as follows: A1{A2, B1} and A2{A1, B2}, and stored in base station A.

[0068] In an exemplary embodiment, target synchronization information carrying the target configuration parameters can be generated in the following manner but is not limited to: constructing initial synchronization information, wherein the initial synchronization information is the information used by the core network to send data to the base station; adding the target configuration parameters to the initial synchronization information to obtain the target synchronization information.

[0069] Optionally, in this embodiment, the initial synchronization information may be, but is not limited to, an AMF CONFIGURATION UPDATE message, which is an NG interface information sent by the core network to the target base station, and may carry the configuration parameters of the serving cell (including PLMN, TAC, NR-CGI, PCI, SSB configuration, etc.) or neighboring cell information (neighboring cell PCI list, neighboring cell NR-CGI list, neighboring cell TAC list, neighboring cell supported frequency bands and frequency information, neighboring cell connection support information, etc.), etc., Figure 6 is a message structure diagram carrying target configuration parameters sent by a core network to a base station according to an embodiment of the present application, such as Figure 6 As shown, the target configuration parameter PA1' target information element id-neighbour-info-NR message of the target serving cell A1 is embedded in the AMF CONFIGURATION UPDATE message to obtain the AMF' message, which is the target synchronization message.

[0070] In this embodiment, a method for updating the configuration of a base station service cell is provided, which is applied to the above-mentioned computer terminal. Multiple base stations deployed in the target area are respectively connected to the core network, each of the base stations corresponds to one or more service cells, and the multiple service cells corresponding to the multiple base stations cover the communication of terminal devices in the target area. Each of the service cells stores the configuration parameters of other service cells that have an adjacent relationship. The method is applied to a target base station among the multiple base stations. Figure 7 is a flowchart of a method for updating the configuration of a serving cell target base station according to an embodiment of the present application, such as Figure 7 As shown, the process includes the following steps:

[0071] Step S702, detecting current configuration parameters of each of the reference serving cells in one or more reference serving cells corresponding to the target base station;

[0072] Step S704, when it is detected that the configuration parameters of the target serving cell in one or more of the reference serving cells are changed from the initial configuration parameters to the target configuration parameters, generating target update information carrying the target configuration parameters, wherein the target update information is used to indicate that the configuration parameters of the target serving cell are currently changed to the target configuration parameters;

[0073] Step S706, sending the target update information to the core network, wherein the core network is used to locate other candidate service cells that have the adjacent relationship with the target service cell from one or more of the service cells corresponding to the target area, and update the configuration parameters of the target service cell stored in the candidate service cell to the target configuration parameters, and the target configuration parameters are used to provide communication switching when the terminal device in the candidate service cell moves to the target service cell.

[0074] Optionally, in this embodiment, the method for the target base station to perform configuration update of the base station service cell may be but is not limited to the following steps: first, the configuration parameters of each service cell in all service cells managed by the target base station are detected, for example, when the target base station is base station A, the current configuration parameters of service cells A1 and A2 managed by base station A are detected; when it is detected that the configuration parameters of the service cell are changed from the initial configuration parameters to the target configuration parameters, target update information carrying the target configuration parameters is generated, for example, when it is detected that the configuration parameters of the service cell A1 are changed from PA1 to PA1', A1 is determined as the target service cell, and the initial configuration parameters are PA1, and the target configuration parameters are PA1', and a target update information RAN' message carrying PA1' is generated, and the specific RAN' message structure is as follows. Figure 5As shown; then the target update information RAN' message is sent to the core network, and the core network obtains the candidate service cells A2 and B1 through the target service cell A1 and its neighboring cell set A1{A2, B1}, and updates the configuration parameter PA1 of A1 stored in the candidate service cell to PA1'.

[0075] In an exemplary embodiment, target update information carrying the target configuration parameters can be generated in the following manner but is not limited to: constructing initial update information, wherein the initial update information is the information used by the base station to upload data to the core network; adding the target configuration parameters to the initial update information to obtain the target update information.

[0076] Optionally, in this embodiment, the initial update information may be but is not limited to a RAN CONFIGURATION UPDATE message, which is an NG interface information sent by the target base station to the core network, and may carry the configuration parameters of the serving cell (including PLMN, TAC, NR-CGI, PCI, SSB configuration, etc.) or neighboring cell information (neighboring cell PCI list, neighboring cell NR-CGI list, neighboring cell TAC list, neighboring cell supported frequency bands and frequency information, neighboring cell connection support information, etc.), such as Figure 5 As shown, the target configuration parameter PA1' purpose information element id-neighbour-info-NR message of the target serving cell A1 is embedded in the RAN CONFIGURATION UPDATE message to obtain a RAN' message, which is a target update message.

[0077] In order to better understand the process of the configuration update method of the above-mentioned base station service cell, the configuration update method process of the above-mentioned base station service cell is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

For example, the service cell A2 managed by base station A is also a neighboring cell of A1, which is not introduced here. The configuration parameters PA1 of the neighboring cell A1 of the service cell B1 stored in base station B are shown in Table 3 below:

[0085] Table 3

[0086] SSB Frequency TAC PLMN PCI NR-CGI 642624 1 46011F 123 123321

[0087] Base station B also stores the configuration of the neighboring cell B2 of service cell B1, which will not be introduced here. When the configuration parameters of service cell A1 are changed, they are changed to PA1', as shown in Table 4 below:

[0088] Table 4

[0089] SSB Frequency TAC PLMN PCI NR-CGI 637344 2 46000F 123 123321

[0090] In the first step, the target base station (base station A) will detect the configuration parameter change of the service cell A1, and trigger the RAN CONFIGURATION UPDATE message to update the configuration parameters of the service cell A1, and embed the changed configuration parameters PA1' of the service cell into the RAN CONFIGURATION UPDATE message to obtain the RAN' message and send it to the core network. Among them, RAN' also includes the neighboring cell information of the service cell A1, including: NR-PCI is 456; NR-CGI is 456654; TAC is 10, etc.

[0091] In the second step, after receiving the RAN' message, the core network searches for other base stations configured with A1 as neighboring cells among all base stations in the target area through the NR-CGI identifier of the service cell A1 carried in the RAN' message, searches for base station B and the corresponding service cell B1, and then sends an AMF CONFIGURATION UPDATE message to update the neighboring cell information of the service cell B1 in base station B, embeds the configuration parameter PA1' into the AMF CONFIGURATION UPDATE message, and sends the AMF' message to base station B.

[0092] In the third step, after receiving the AMF' message, base station B updates the neighboring cell configuration in the serving cell B1 according to the AMF' message, and updates PA1 to PA1'. The updated configuration is shown in Table 5 below:

[0093] Table 5
