Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, apparatus, device and storage medium. Background Art

[0002] To meet user network needs, sharing base station resources between different operators is a common approach. Specifically, a source base station sends a configuration transmission message to the source base station's management function network element. The source base station's management function network element sends the tracking area identity (TAI) in the received configuration transmission message to the domain name system (DNS). Furthermore, the DNS queries the management function network element of the target base station corresponding to the TAI and sends the query result to the management function network element of the source base station, establishing a communication interface between the source and target base stations.

[0003] However, the information included in the TAI in the above method is not clearly defined, resulting in DNS query failures or repeated DNS queries, inability to establish a communication interface, and high DNS load. Therefore, how to efficiently establish a communication interface between base stations is a technical problem that needs to be solved urgently. Summary of the Invention

[0006] In a possible implementation, the above method further includes: when the target communication link status is unavailable, sending an interface establishment failure message to the source base station.

[0007] In a possible implementation, the above method further includes: updating the base station interface mapping relationship when the communication link status between different base stations and corresponding management function network elements changes; and when a new base station exists, adding the identifier of the new base station and the communication link status between the new base station and the corresponding management function network element to the base station interface mapping relationship.

[0008] In one possible implementation, when the target communication link status is an available state, a communication interface is established between the source base station and the target base station, including: sending a request interface establishment message to the management function network element of the target base station; the request interface establishment message is used to request to establish a communication interface between the source base station and the target base station; in response to a confirmation interface establishment message sent by the management function network element of the target base station, forwarding the confirmation interface establishment message to the source base station.

[0009] According to a second aspect, a communication device is provided, which is applied to a management function network element of a source base station, and the communication device includes a receiving unit, a query unit and a processing unit; the receiving unit is used to receive a configuration transmission message sent by the source base station; the configuration transmission message includes an identifier of the target base station, and the configuration transmission message is used to request to establish a communication interface between the source base station and the target base station; the query unit is used to query the target communication link status between the target base station and the corresponding management function network element from a preset base station interface mapping relationship based on the identifier of the target base station after the receiving unit receives the configuration transmission message sent by the source base station; the base station interface mapping relationship includes identifiers of different base stations and the communication link status between different base stations and the corresponding management function network elements; the processing unit is used to establish a communication interface between the source base station and the target base station when the target communication link status is in an available state.

[0010] In a possible implementation, the communication device further includes a sending unit configured to send an interface establishment failure message to the source base station when the target communication link is in an unavailable state.

[0011] In one possible implementation, the above-mentioned processing unit is also used to: update the base station interface mapping relationship when the communication link status between different base stations and corresponding management function network elements changes; when there is a new base station, add the identifier of the new base station and the communication link status between the new base station and the corresponding management function network element to the base station interface mapping relationship.

[0012] In one possible implementation, the above-mentioned processing unit is specifically used to: send a request interface establishment message to the management function network element of the target base station; the request interface establishment message is used to request to establish a communication interface between the source base station and the target base station; in response to the confirmation interface establishment message sent by the management function network element of the target base station, forward the confirmation interface establishment message to the source base station.

[0016] The technical solution provided by the present application brings at least the following beneficial effects: In the prior art, the management function network element of the target base station corresponding to the TAI is usually queried through DNS to establish a communication interface between the source base station and the target base station. However, since the information included in the TAI is not clearly specified, the DNS query fails or the DNS is repeatedly queried, so that the communication interface cannot be established, and the DNS load is high. The present application receives the configuration transmission message sent by the source base station, and based on the identifier of the target base station, queries the target communication link status between the target base station and the corresponding management function network element from the preset base station interface mapping relationship. Among them, the base station interface mapping relationship includes the identifiers of different base stations and the communication link status between different base stations and the corresponding management function network element. In this way, the target communication link status can be obtained based on the identifier of the target base station and the base station interface mapping relationship, avoiding the situation of DNS query failure or repeated query, and reducing the DNS load. Moreover, when the target communication link status is in an available state, the communication interface between the source base station and the target base station is efficiently established.

[0027] Before introducing the communication method provided by this application in detail, a brief introduction to the implementation environment (implementation architecture) involved in this application is first given.

[0028] The communication method provided in the embodiments of the present application can be applied to a communication system. Figure 1 FIG. 1 shows a schematic structural diagram of the communication system 10. Figure 1 As shown, the communication system 10 includes a source base station 11, a management function network element 12 of the source base station, a management function network element 13 of the target base station, and a target base station 14. The source base station 11 is connected to the management function network element 12 of the source base station. The source base station 11 and the management function network element 12 of the source base station can be connected in a wired manner or in a wireless manner, which is not limited in this embodiment of the present application.

[0029] The management function network element 12 of the source base station is connected to the management function network element 13 of the target base station. The management function network element 12 of the source base station and the management function network element 13 of the target base station can be connected by wire or by wireless, which is not limited in this embodiment of the present application. The management function network element 13 of the target base station is connected to the target base station 14. The management function network element 13 of the target base station and the target base station 14 can be connected by wire or by wireless, which is not limited in this embodiment of the present application.

[0030] The source base station 11 may be configured to receive a measurement report sent by a user equipment, where the measurement report includes: a signal measurement value of the source base station measured by the user equipment, a signal measurement value of a target base station measured by the user equipment, and an identifier of the target base station.

[0031] The source base station 11 can also be used to send a configuration transmission message to the management function network element 12 of the source base station. The configuration transmission message includes: the identifier of the source base station, the identifier of the target base station, the mobile country code (MCC), the mobile network code (MNC), and the tracking area code (TAC).

[0032] The management function network element 12 of the source base station may be configured to receive a configuration transmission message sent by the source base station 11 , where the configuration transmission message includes an identifier of the target base station.

[0033] The management function network element 12 of the source base station can also be used to process the received configuration transmission message, for example, based on the identifier of the target base station, query the target communication link status between the target base station and the corresponding management function network element from the preset base station interface mapping relationship; the base station interface mapping relationship includes the identifiers of different base stations and the communication link status between different base stations and the corresponding management function network element; when the target communication link status is in an available state, a communication interface is established between the source base station and the target base station.

[0034] The management function network element 13 of the target base station can be used to receive the interface establishment request message sent by the management function network element 12 of the source base station when the target communication link status is available, and forward the interface establishment request message to the target base station 14.

[0035] The management function network element 13 of the target base station may also be configured to receive a message for confirming interface establishment sent by the target base station 14 and forward the message for confirming interface establishment to the management function network element 12 of the source base station.

[0036] The target base station 14 may be configured to receive a request interface establishment message sent by the management function network element 13 of the target base station, and send a confirmation interface establishment message to the management function network element 13 of the target base station.

[0037] In one application scenario, the source base station 11 and the target base station 14 may be fourth-generation mobile communication technology base stations (4G base stations), and the management function network element 12 of the source base station and the management function network element 13 of the target base station may be mobility management entities (MMEs). The source base station 11 and the management function network element 12 of the source base station may communicate via an S1 interface, and the management function network element 13 of the target base station and the target base station 14 may communicate via an S1 interface. In this scenario, the communication interface between the source base station 11 and the target base station 14 established in this application may be an X2 interface.

[0038] In another application scenario, the source base station 11 and the target base station 14 can be fifth-generation mobile communication technology base stations (5G base stations), and the management function network element 12 of the source base station and the management function network element 13 of the target base station can be access and mobility management functions (AMF). The source base station 11 and the management function network element 12 of the source base station can communicate through the NG interface, and the management function network element 13 of the target base station can communicate with the target base station 14 through the NG interface. In this scenario, the communication interface between the source base station 11 and the target base station 14 established in this application can be an Xn interface.

[0039] It should be noted that the source base station 11 and the target base station 14 belong to different operators.

[0040] For ease of understanding, the communication method provided in this application is described in detail below with reference to the accompanying drawings.

[0041] Figure 2 is a flow chart showing a communication method according to an exemplary embodiment. The method can be applied to a management function network element of a source base station, such as Figure 2 As shown, the communication method provided in the embodiment of the present application includes the following steps:

[0042] S201. The management function network element of a source base station receives a configuration transmission message sent by the source base station.

[0043] The configuration transmission message includes an identifier of the target base station, and the configuration transmission message is used to request to establish a communication interface between the source base station and the target base station.

[0044] As a possible implementation, the source base station receives a measurement report sent by the user equipment, where the measurement report includes: a signal measurement value of the source base station measured by the user equipment, a signal measurement value of the target base station measured by the user equipment, and an identifier of the target base station. The management function network element of the source base station receives a configuration transmission message sent by the source base station, where the configuration transmission message includes: the identifier of the source base station, the identifier of the target base station, the MCC, the MNC, and the TAC.

[0045] S202: The management function network element of the source base station queries the target communication link state between the target base station and the corresponding management function network element from a preset base station interface mapping relationship based on the identifier of the target base station.

[0046] The base station interface mapping relationship includes identifiers of different base stations and communication link states between different base stations and corresponding management function network elements.

[0047] As one possible implementation, the base station interface mapping relationship includes the identifiers of different base stations and the communication link states between different base stations and corresponding management function network elements. The source base station is connected to the core networks of the different base stations included in the base station interface mapping relationship. The management function network element of the source base station queries the target communication link state between the target base station and the corresponding management function network element from the preset base station interface mapping relationship based on the identifier of the target base station.

[0048] For example, the preset base station interface mapping relationship may be shown in Table 1 below:

[0049] Table 1: Preset base station interface mapping

[0050] Base station identification Communication link status Base Station A Available status Base Station B Unavailable status Base Station C Available status Base Station D Unavailable status

[0051] Exemplarily, the management function network element of the source base station queries the target communication link status between base station A and the corresponding management function network element from Table 1 above based on the identifier of the target base station (taking the identifier of the target base station as base station A as an example), and obtains that the target communication link status between base station A and the corresponding management function network element is an available state.

[0052] Exemplarily, the management function network element of the source base station queries the target communication link status between base station B and the corresponding management function network element from Table 1 above based on the identifier of the target base station (taking the identifier of the target base station as base station B as an example), and obtains that the target communication link status between base station B and the corresponding management function network element is unavailable.

[0053] As another possible implementation, the base station interface mapping relationship includes an identifier of a first base station, an identifier of a second base station, and a communication link state between the second base station and a corresponding management function network element, wherein the first base station is connected to a core network of the second base station. Based on the identifier of the source base station and the identifier of the target base station, the management function network element of the source base station queries a preset base station interface mapping relationship for a target communication link state in which the identifier of the first base station is the identifier of the source base station and the identifier of the second base station is the identifier of the target base station.

[0054] For example, the preset base station interface mapping relationship may be shown in Table 2 below:

[0055] Table 2: Preset base station interface mapping

[0056] Identification of the first base station Identifier of the second base station Communication link status Base Station 2 Base Station F Available status Base Station 2 Base Station G Unavailable status Base Station 3 Base Station H Available status Base Station 4 Base Station J Unavailable status

[0057] For example, taking base station 2 as the identifier of the source base station and base station G as the identifier of the target base station, the management function network element of the source base station is based on base station 2 and base station G, and queries from Table 2 above that the target communication link status of the first base station identified as base station 2 and the second base station identified as base station G is unavailable.

[0058] For example, taking base station 2 as the identifier of the source base station and base station F as the identifier of the target base station, the management function network element of the source base station is based on base station 2 and base station F, and queries from Table 2 above that the target communication link status of the first base station identified as base station 2 and the second base station identified as base station F is available.

[0059] It should be noted that the base station can communicate with the management function network element corresponding to the base station.

[0060] S203: When the target communication link status is available, the management function network element of the source base station establishes a communication interface between the source base station and the target base station.

[0061] As a possible implementation method, the management function network element of the source base station sends a request interface establishment message to the target base station when the target communication link status is available, and establishes a communication interface between the source base station and the target base station in response to the confirmation interface establishment message sent by the target base station.

[0062] For the specific implementation of this step, please refer to the subsequent description of the embodiments of this application and will not be repeated here.

[0063] It is understandable that in the prior art, the management function network element of the target base station corresponding to the TAI is usually queried by DNS to establish a communication interface between the source base station and the target base station. However, since the information included in the TAI is not clearly specified, the DNS query fails or the DNS is repeatedly queried, thereby failing to establish the communication interface and causing a high DNS load. The present application receives a configuration transmission message sent by the source base station and queries the target communication link status between the target base station and the corresponding management function network element from a preset base station interface mapping relationship based on the identifier of the target base station. Among them, the base station interface mapping relationship includes the identifiers of different base stations and the communication link status between different base stations and the corresponding management function network element. In this way, the target communication link status can be obtained based on the identifier of the target base station and the base station interface mapping relationship, thereby avoiding the situation of DNS query failure or repeated query, and reducing the DNS load. Moreover, when the target communication link status is in an available state, the communication interface between the source base station and the target base station is efficiently established.

[0064] In some embodiments, when the target communication link status is unavailable, such as Figure 3 As shown, the communication method provided in the embodiment of the present application further includes:

[0065] S301. When the target communication link status is unavailable, the management function network element of the source base station sends an interface establishment failure message to the source base station.

[0066] As a possible implementation, the management function network element of the source base station sends an interface establishment failure message to the source base station when the target communication link is unavailable. The source base station receives the interface establishment failure message and sends a configuration transmission message to the management function network element of the source base station based on a preset period.

[0067] It can be understood that, when the target communication link status is unavailable, the present application sends an interface establishment failure message to the source base station, thereby avoiding repeated DNS queries due to unclear TAI information, thereby reducing the DNS load.

[0068] In some embodiments, when the communication link status changes or a new base station is created, the communication method provided in the embodiments of the present application further includes:

[0069] S401. The management function network element of the source base station updates the base station interface mapping relationship when the communication link status between different base stations and corresponding management function network elements changes.

[0070] As a possible implementation method, the management function network element of the source base station obtains the communication link status between different base stations and the corresponding management function network elements in the base station interface mapping relationship, and updates the base station interface mapping relationship when the status between different base stations and the corresponding management function network elements changes (for example, from an available state to an unavailable state, or from an unavailable state to an available state).

[0071] S402: If a new base station exists, the management function network element of the source base station adds the identifier of the new base station and the communication link status between the new base station and the corresponding management function network element to the base station interface mapping relationship.

[0072] As a possible implementation method, when the source base station is connected to the core network of the newly built base station, the management function network element of the source base station adds the identifier of the newly built base station and the communication link status (such as available status, unavailable status) between the corresponding management function network element to the base station interface mapping relationship.

[0073] It can be understood that this application updates the base station interface mapping relationship in a timely manner when the communication link status between the base station and the corresponding management function network element changes, or when a new base station is built, thereby making the subsequent establishment of the communication interface between the source base station and the target base station more efficient.

[0074] In some embodiments, in order to establish a communication interface between the source base station and the target base station, such as Figure 4 As shown, the above S203 can be implemented as follows:

[0075] S2031. The management function network element of the source base station sends a request interface establishment message to the management function network element of the target base station.

[0076] The interface establishment request message is used to request establishment of a communication interface between the source base station and the target base station.

[0077] As a possible implementation, the management function network element of the source base station sends a request interface establishment message to the management function network element of the target base station. The management function network element of the target base station receives the request interface establishment message and forwards the request interface establishment message to the target base station.

[0078] S2032. The management function network element of the source base station responds to the interface establishment confirmation message sent by the management function network element of the target base station and forwards the interface establishment confirmation message to the source base station.

[0079] As a possible implementation, the management function network element of the target base station receives the confirmation interface establishment message sent by the target base station and forwards the confirmation interface establishment message to the management function network element of the source base station. The management function network element of the source base station receives the confirmation interface establishment message and forwards the confirmation interface establishment message to the source base station.

[0080] It can be understood that when the target communication link status obtained based on the identification of the target base station and the preset base station interface mapping relationship is an available state, a request interface establishment message is sent to the target base station to confirm that the target communication link status is an available state, thereby efficiently establishing a communication interface between the source base station and the target base station.

[0081] Figure 5 A communication device 500 is shown according to an exemplary embodiment. Figure 5 As shown, the communication device 500 provided in this embodiment of the present application includes a receiving unit 501, a query unit 502 and a processing unit 503.

[0082] The receiving unit 501 is configured to receive a configuration transmission message sent by a source base station. The configuration transmission message includes an identifier of a target base station and is used to request to establish a communication interface between the source base station and the target base station.

[0083] The query unit 502 is configured to query the target communication link status between the target base station and the corresponding management function network element from a preset base station interface mapping relationship based on the identifier of the target base station after the receiving unit 501 receives the configuration transfer message sent by the source base station. The base station interface mapping relationship includes the identifiers of different base stations and the communication link status between different base stations and the corresponding management function network elements.

[0084] The processing unit 503 is configured to establish a communication interface between the source base station and the target base station when the target communication link state is an available state.

[0085] Optionally, when the target communication link status is unavailable, such as Figure 5 As shown, the communication device 500 provided in this embodiment of the present application further includes a sending unit 504.

[0086] The sending unit 504 is configured to send an interface establishment failure message to the source base station when the target communication link status is unavailable.

[0087] Optionally, when the communication link status changes or a new base station is built, Figure 5 As shown, the processing unit 503 provided in this embodiment of the present application is further configured to:

[0088] When the communication link status between different base stations and corresponding management function network elements changes, the base station interface mapping relationship is updated.

[0089] In the case that a new base station exists, the identifier of the new base station and the communication link status between the new base station and the corresponding management function network element are added to the base station interface mapping relationship.

[0090] Optionally, in order to establish a communication interface between the source base station and the target base station, such as Figure 5 As shown, the processing unit 503 provided in this embodiment of the present application is specifically configured to:

[0091] Send a request interface establishment message to the management function network element of the target base station. The request interface establishment message is used to request to establish a communication interface between the source base station and the target base station.

[0092] In response to the interface establishment confirmation message sent by the management function network element of the target base station, the interface establishment confirmation message is forwarded to the source base station.
