[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The application environment of the satellite neighbor area determination method is first described below.

[0045] The satellite neighbor cell determination method provided in the embodiment of the present application can be applied to the application environment shown in FIG. 1 . Among them, the satellite base station 101 and the satellite base station 102 are adjacent base stations. The satellite base station 102 can send interface configuration information to the satellite base station 101, and the interface configuration information includes the non-terrestrial network NTN auxiliary information of the cell of the satellite base station 102. Subsequently, the satellite base station 101 determines the distance between the cell of the satellite base station 101 and the cell of the satellite base station 102 based on the NTN auxiliary information of the cell of the satellite base station 102 and the NTN auxiliary information of the cell of the satellite base station 101.

Depending on the specific application scenario, the satellite base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The satellite base station can be used to replace the received air frames with Internet Protocol (IP) packets, as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The satellite base station can also coordinate the attribute management of the air interface. For example, the satellite base station involved in the embodiment of the present application may be an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long-term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), etc., which is not limited in the embodiment of the present application. In some network structures, the satellite base station may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged separately.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In an exemplary embodiment, Figure 2As shown, a satellite neighbor determination method is provided, and the satellite neighbor determination method is applied to a target satellite base station, and the target satellite base station may be the satellite base station 101 in FIG. 1 . The satellite neighbor determination method includes S201-S203:

[0049] S201. Receive interface configuration information sent by a neighboring base station of a target satellite base station.

[0050] The adjacent base station is a base station within a preset range of the target satellite base station, and the interface configuration information includes non-terrestrial network NTN auxiliary information of the cell of the adjacent base station.

[0051] In the present application, when it is necessary to determine the neighboring cells of the target satellite base station, the interface configuration information sent by the neighboring base stations of the target satellite base station can be first received.

[0052] The target satellite base station may be any satellite base station in the NTN.

[0053] It should be understood that the preset range of the target satellite base station is not limited in the embodiment of the present application, and can be specifically set according to actual conditions, and can be, for example, a range of 10 kilometers, 100 kilometers, 200 kilometers, etc. For example, if the preset range is 100 kilometers, the target satellite base station can determine all satellite base stations within the range of 100 kilometers as neighboring base stations.

[0054] It should be understood that the embodiments of the present application do not limit how the target satellite base station receives the interface configuration information sent by the neighboring base stations of the target satellite base station. In some embodiments, the target satellite base station can receive the interface configuration information sent by the neighboring base stations of the target satellite base station through the network interface. Accordingly, after the target satellite base station is started, the target satellite base station can establish a network interface for interaction with the neighboring base stations.

[0055] Among them, the above-mentioned network interface can be an Xn interface.

[0056] For example, Figure 3 A schematic diagram of a control plane protocol stack of an Xn interface provided in an embodiment of the present application, such as Figure 3 As shown, the control plane protocol stack of the Xn interface may include a physical layer, a data link layer, a stream control transmission protocol (SCTP) layer, and an Internet Protocol (IP) layer.

[0057] Exemplarily, the above interface configuration information can be sent by the adjacent base station to the target satellite base station through the Xn configuration acquisition request and Xn configuration acquisition response corresponding to the Xn interface. In addition to the interface configuration information, the interface configuration information can also include at least one of the following information: a global base station node identifier (Global NG-RAN Node ID), a tracking area code support list (TAI Support List), a service cell list (List of Served Cells), etc.

[0058] The Xn configuration acquisition request may be an XN SETUP REQUEST message of a standard Xn interface, or other newly defined messages of a standard Xn interface. The Xn configuration acquisition response may be an XN SETUPRESPONSE or XN SETUP FAILURE message of a standard Xn interface, or other newly defined messages of a standard Xn interface. It should be understood that the embodiment of the present application does not limit the above-mentioned NTN auxiliary information, which may be an example of information representing a position corresponding to the NTN-R17 standard, or a code stream encoded by the NTN-R17 standard, or a part of the information elements of the NTN-R17 standard. Exemplarily, the NTN auxiliary information may specifically include ephemeris information broadcast by a cell.

[0059] S202: Determine the distance between the cell of the target satellite base station and the cell of the adjacent base station according to the NTN auxiliary information of the cell of the adjacent base station and the NTN auxiliary information of the cell of the target satellite base station.

[0060] In this step, after receiving the interface configuration information sent by the adjacent base station of the target satellite base station, the target satellite base station can determine the distance between the cell of the target satellite base station and the cell of the adjacent base station based on the NTN auxiliary information of the cell of the adjacent base station and the NTN auxiliary information of the cell of the target satellite base station.

[0061] In some embodiments, the target satellite base station may first determine the location information of the cell of the neighboring base station based on the NTN auxiliary information of the cell of the neighboring base station, and determine the location information of the cell of the target satellite base station based on the NTN auxiliary information of the cell of the target satellite base station. Subsequently, the target satellite base station determines the distance between the cell of the target satellite base station and the cell of the neighboring base station based on the location information of the cell of the neighboring base station and the location information of the cell of the target satellite base station.

[0062] Exemplarily, if the NTN auxiliary information directly includes the location information of the satellite base station's cell, the target satellite base station can directly obtain the location information of the neighboring base station's cell from the NTN auxiliary information of the neighboring base station's cell, and directly obtain the location information of the target satellite base station's cell from the NTN auxiliary information of the target satellite base station's cell.

[0063] Exemplarily, if the NTN auxiliary information includes ephemeris information, the target satellite base station can infer the location information of the cell of the neighboring base station based on the ephemeris information of the cell of the neighboring base station, and infer the location information of the cell of the target satellite base station based on the ephemeris information of the cell of the target satellite base station.

[0064] S203. Determine neighboring cell relationship information of the target satellite base station according to the distance between the cell of the target satellite base station and the cell of the adjacent base station, where the neighboring cell relationship information is used to indicate whether the cell of the adjacent base station is a neighboring cell of the cell of the target satellite base station.

[0065] In this step, after the target satellite base station determines the distance between the cell of the target satellite base station and the cell of the adjacent base station, the neighboring cell relationship information of the target satellite base station can be determined according to the distance between the cell of the target satellite base station and the cell of the adjacent base station.

[0066] In some embodiments, if the distance between the cell of the target satellite base station and the cell of the neighboring base station is less than or equal to a distance threshold, the neighboring cell relationship information indicates that the cell of the neighboring base station is a neighboring cell of the cell of the target satellite base station. If the distance between the cell of the target satellite base station and the cell of the neighboring base station is greater than the distance threshold, the neighboring cell relationship information indicates that the cell of the neighboring base station is not a neighboring cell of the cell of the target satellite base station.

[0067] Among them, the above-mentioned distance threshold can be specifically set based on the actual situation, and the embodiment of the present application does not limit this. For example, it can be 0.1 km, 0.5 km, 1 km, etc.

[0068] In other embodiments, after the target satellite base station determines the neighbor relation information of the target satellite base station, the neighbor relation information may also be updated based on the change of the NTN auxiliary information.

[0069] Exemplarily, if the first configuration update information and / or the second configuration update information are obtained, the target satellite base station updates the neighbor relationship information of the target satellite base station, the first configuration update information is used to update the NTN auxiliary information of the cell of the adjacent base station, and the second configuration update information is used to update the NTN auxiliary information of the cell of the target satellite base station.

[0070] The second configuration update information can be obtained from the target satellite base station. The first configuration update information can be carried in a satellite base station node configuration update message. After receiving the satellite base station node configuration update message, the target satellite base station can send a satellite base station node configuration update confirmation message to the adjacent base station.

[0071] The node configuration update message may be a NG-RAN NODE CONFIGURATION UPDATE message of a standard Xn interface or other newly defined messages of a standard Xn interface. The satellite base station node configuration update confirmation message may be a NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE message of a standard Xn interface or other newly defined messages of an Xn interface.

[0072] The satellite neighbor determination method provided in the embodiment of the present application, first, the target satellite base station receives the interface configuration information sent by the neighboring base station of the target satellite base station, the neighboring base station is a base station within the preset range of the target satellite base station, and the interface configuration information includes the non-terrestrial network NTN auxiliary information of the cell of the neighboring base station. Subsequently, the target satellite base station determines the distance between the cell of the target satellite base station and the cell of the neighboring base station based on the NTN auxiliary information of the cell of the neighboring base station and the NTN auxiliary information of the cell of the target satellite base station. Finally, the target satellite base station determines the neighbor relationship information of the target satellite base station based on the distance between the cell of the target satellite base station and the cell of the neighboring base station, and the neighbor relationship information is used to indicate whether the cell of the neighboring base station is a neighbor of the cell of the target satellite base station. The satellite neighbor determination method, with NTN auxiliary information in the interface configuration information, determines the distance between the cell of the target satellite base station and the cell of the neighboring base station through the NTN auxiliary information of the cell of the neighboring base station and the cell of the target satellite base station, so that the neighbor relationship information of the target satellite base station can be judged by the distance between the cell of the target satellite base station and the cell of the neighboring base station. Since the distance is used as the basis for judging the neighboring area, the accuracy of generating the neighboring area relationship of the satellite base station is improved.

[0073] The following further describes how to generate neighbor relationship information.
