[0256] In the embodiments of the present invention, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0257] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0258] 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.

[0259] In order to facilitate understanding of the solution of this application, the relevant contents involved in this application are first introduced.

[0260] The architecture and functional implementation of the existing fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) application layer SEAL service are as follows:

[0261] 1) Introduction to the SEAL function at the application layer

[0262] Due to the emergence of various new vertical services such as IoT, positioning, Internet of Vehicles, and drones, the 3rd Generation Partnership Project (3GPP) SA6 (focusing on the application layer) working group has written all the common functions of some vertical services into the Service Enabler Architecture Layer for Verticals (SEAL) standard, such as Figure 1 As shown, it includes common functions such as group management, positioning, configuration, file upload / download, and notification. It also defines the architecture, function modules, interfaces, northbound APIs, and deployment methods that enable the service. When new services emerge, the functions defined by SEAL are directly used for the above common service capabilities (and expanded if necessary), while other unique services can be defined in separate service standards.

[0263] Among them, the SEAL server can interact with the SEAL client (Client) inside the terminal (UE) through the SEAL-UU port to obtain the terminal's configuration and capabilities, and obtain the corresponding network data in combination with the 3GPP network, and then finally report to the vertical application (VAL server) through the SEAL-S interface for use by vertical industries.

[0264] 2) Introduction to the existing application layer IoT service architecture and functions

[0265] The existing application layer IoT service architecture is based on the SEAL architecture, such as Figure 2 As shown in the figure. After the IoT Management Server (IoTMS) obtains the requirements for certain IoT devices from the IoT Vertical Application Server (IoT VAL server), it sends the requirements to the IoT Management Client (IoTMC) of the terminal, and interacts with the 3rd Generation Partnership Project (3GPP) network through the N33 / T8 interface to collect the network information of the corresponding IoT device. Then, the information obtained from the terminal UE and the 3GPP network is processed and reported to the IoT VAL server.

[0266] 3) Existing application layer access technology

[0267] The existing application enabling layer, such as SEAL, EDGEAPP, and IoT management server based on SEAL, currently only supports 3GPP access, such as the 4th Generation Mobile Communication Technology (4G) Long Term Evolution (LTE), 5G New Radio (NR), etc., and does not yet support satellite access. For example, in remote mountainous areas, sea areas and other scenarios without base station coverage, how can herders locate a large number of sheep, and how can shipping companies manage their own ships? These scenarios require satellites as an auxiliary means of base stations to participate in communication services.

[0268] However, the existing application enabling layer does not take satellite access into consideration and cannot meet the communication needs of remote mountainous areas, sea areas, polar regions and other places that are not covered by base stations.

[0269] In order to solve the above technical problems, the embodiments of the present application provide a satellite access method, device, equipment and medium, wherein the method and the device are based on the same application concept. Since the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0270] See also Figure 3 , which is the application layer IoT management function architecture provided by the embodiment of the present invention; this architecture is an enhancement based on the existing SEAL-IoT service architecture. Specifically, the interaction between the IoT management server and the non-ground network server (SatelliteControl Server) is newly added, which is mainly used to obtain satellite-related information, etc. At the same time, an operation administration and maintenance (OAM) interface is added, so that the IoT management server can interact with the network management in the 3GPP system through the OAM interface configuration to collect corresponding management information, thereby meeting the needs of the vertical industry of the Internet of Things. In addition, the interface IoTMC-UU is also enhanced to support reporting of relevant information through satellite access. The method of the embodiment of the present invention is implemented based on this architecture.

[0271] like Figure 4 As shown, it is a schematic diagram of a flow chart of a satellite access method provided by an embodiment of the present invention, and the method is applied to a terminal, wherein the method specifically includes:

[0272] Step 401, receiving first information sent by a first server;

[0273] Here, the first server may be an IoT management server.

[0274] The first information includes at least one of the following information:

[0275] Information related to satellite access;

[0276] Satellite coverage information;

[0277] ephemeris information;

[0278] Subscription events for endpoints.

[0279] Optionally, the information related to satellite access includes one or more of the following:

[0280] Satellite access method;

[0281] The type of satellite being accessed;

[0282] The satellite ID of the access;

[0283] Access priority;

[0284] Dedicated satellite access.

[0285] Step 402, determining and accessing a target satellite according to the first information;

[0286] The satellite access method of the embodiment of the present invention enables the terminal to support application layer communication through satellite access through the first information related to satellite access, thereby meeting the communication needs between the terminal and the application server in scenarios such as remote mountainous areas, sea surfaces, and polar regions where there is no base station coverage.

[0287] As an optional implementation, the method of the embodiment of the present invention may further include:

[0288] 1. Sending a first request to the first server, where the first request is used to request reporting or updating terminal capability information, and the first request carries the terminal capability information; the terminal capability information is used to assist the first server in determining the first information;

[0289] Optionally, the terminal capability information includes one or more of the following information:

[0290] Identification of the servicing satellite;

[0291] Supported satellite access methods;

[0292] Supported satellite access types.

[0293] 2. Receive a first response to the first request sent by the first server. Here, the first response is used to notify the terminal that the first server has accepted the terminal capability information reported by the terminal, so that the first server can subsequently process the first information.

[0294] This implementation method illustrates that the terminal supports reporting and updating of terminal capabilities, and specifically supports reporting and updating of satellite access capabilities.

[0295] Here, the terminal capability information may further include: an identifier of the terminal (such as a Generic Public Subscription Identifier (GPSI) or a group ID) and a device type, and the like.

[0296] Specifically, when the first request is used to request reporting of terminal capability information, the first request may be a UE capability report request. When the first request is used to request updating of terminal capability information, the first request may be a UE capability update request.

[0297] Embodiment 1:

[0298] The terminal supports reporting and updating of onboard store-and-forward capabilities

[0299] After the terminal that supports satellite access registers with the 5GC / EPC network, the internal IoT management client needs to report the terminal capability information to the application layer IoT management server, including the UE ID, device type, and information related to on-board storage and forwarding.

[0300] See also Figure 5 The specific implementation process is as follows:

[0301] 1. The IoT management client sends a UE capability report / update request to the IoT management server to report or update the terminal's capabilities;

[0302] Here, in addition to the UE identifier (such as GPSI or group ID), UE type, and supported positioning capabilities, the request also needs to report the supported access methods (such as satellite access, access type, specific satellite identifier, etc.). For example, 3GPP access capabilities: satellite (low orbit LEO, medium orbit MEO, high orbit GEO), satellite identifier.

[0303] 2. After receiving the terminal capability information reported by the IoT management client, the IoT management server authenticates the terminal based on the stored information.

[0304] 3. If the authentication is successful, the IoT management server accepts the IoT management client request and sends a response, while storing or updating the terminal capability information.

[0305] As an optional implementation, the method of the embodiment of the present invention may further include:

[0306] Sending a second request to the first server, where the second request is used to request access information required by the network;

[0307] Accordingly, the above step 401, receiving the first information sent by the first server, may include:

[0308] A second response sent by the first server is received, where the second response includes the first information, and the first information is information related to satellite access queried through the first server.

[0309] This implementation method illustrates that the terminal can actively query the access information required by the network.

[0310] Embodiment 2: The terminal actively queries the access information required by the network

[0311] Before accessing the network, IoT devices can actively query the IoT management server for their information, such as the access type supported by the network, access priority, etc.

[0312] See also Figure 6 The specific implementation process is as follows:

[0313] 1) The IoT management client inside the terminal sends a UE information query request to the IoT management server to query the terminal information, carrying the UE identifier (such as GPSI or group ID), UE type, and requested information (such as the 3GPP access type or access priority recommended by the application layer). An example is as follows:

[0314] 1. Prefer 3GPP access: Satellite (priority 1)

[0315] Preferred satellite type: LEO

[0316] 2. Prefer 3GPP access: 5G NR (priority 2)

[0317] 2) After receiving the information requested by the IoT management client, the IoT management server authenticates the terminal based on the stored information.

[0318] 3) If the authentication is successful, the IoT management server accepts the IoT management client request, responds and sends the requested information (such as the 3GPP access type or access priority recommended by the application layer).

[0319] As an optional implementation, the above step 401, receiving the first information sent by the first server, may include:

[0320] A third request is received from the first server, wherein the third request is used to request a terminal to report information related to a target communication service, the third request includes a preset reporting condition and the first information, and the first information includes information related to satellite access.

[0321] It should be noted that the first information is determined by the first server based on the information in the request, the terminal capability information and its own configuration information.

[0322] Here, the third request may be a traffic reporting request for the terminal.

[0323] Here, the preset reporting condition may be a reporting cycle, a reporting delay, a reporting quantity, and the like.

[0324] Accordingly, the method of the embodiment of the present invention may further include:

[0325] When the preset reporting condition is met, a third response is sent to the first server based on the first information, where the third response includes information related to the target communication service.

[0326] Here, when the preset reporting conditions are met, based on the information related to satellite access, such as the satellite access mode and access type sent by the first server, the information related to the target communication service requested in the third request is sent to the first server.

[0327] In this implementation, the terminal can send corresponding information related to the communication service according to the information related to the satellite access sent by the first server. In this way, the communication demand between the terminal and the application server (first server) can be met through satellite access.

[0328] As an optional implementation, the method of the embodiment of the present invention may further include:

[0329] Sending a fourth request to the first server, where the fourth request is used to request satellite coverage information of a subscription terminal;

[0330] That is, the terminal subscribes to the satellite coverage information change message from the first server.

[0331] Accordingly, the above step 401, receiving the first information sent by the first server, may include:

[0332] A fourth response sent by the first server is received, where the fourth response includes the first information, and the first information is the satellite coverage information.

[0333] Here, the first server needs to first obtain satellite coverage information (for the specific process, see the description of the first server side), and then send the satellite coverage information to the terminal, that is, receive the fourth response sent by the first server. It should be noted that the satellite coverage information is the satellite coverage information formatted by the first server.

[0334] Accordingly, the method of the embodiment of the present invention may further include:

[0335] Determine, according to the satellite coverage information, the available time for the terminal to use the satellite for the corresponding communication service;

[0336] Within the available time, an uplink message is sent to the first server.

[0337] It should be noted that after receiving the satellite coverage information, the terminal can determine the available time during which the terminal can use the satellite for corresponding communication services (such as surfing the Internet, making phone calls, etc.). That is, if the terminal is within the satellite coverage area and needs to initiate an uplink message, it needs to initiate the corresponding uplink message within the available time as required.

[0338] In this implementation, the terminal can send a corresponding uplink message within the available time according to the satellite coverage information sent by the first server. In this way, the communication requirements between the terminal and the application server (first server) can be met through satellite access.

[0339] As an optional implementation, the first information includes the subscription event for the terminal; accordingly, the method of the embodiment of the present invention may further include:

[0340] In a case where the subscription event for the terminal meets a first preset subscription condition, generating a first subscription event report;

[0341] Sending the first subscription event report to the first server.

[0342] Here, the first server initiates a subscription event for the terminal to the terminal, such as the terminal rate of accessing a certain satellite, and carries the corresponding identifier and trigger condition (i.e., the first preset subscription condition); afterwards, when the subscription event meets the first preset subscription condition, such as the required trigger reporting time has arrived, the terminal generates a first subscription event report corresponding to the subscription event and returns it to the first server. In this way, the first server can obtain information related to the satellite on the terminal side, and then realize subsequent on-board communication services between devices.

[0343] The satellite access method of an embodiment of the present invention comprises the following steps: a terminal receives first information sent by a first server; based on the first information, a target satellite is determined and accessed; wherein the first information comprises at least one of the following information: information related to satellite access; satellite coverage information; ephemeris information; and subscription events for the terminal; in this way, through the first information related to satellite access, the terminal has the ability to support application layer communication through satellite access, thereby meeting the communication requirements between the terminal and the application server in scenarios without base station coverage, such as remote mountainous areas, sea surfaces, and polar regions.

[0344] like Figure 7 As shown, it is a schematic diagram of the process of the satellite access method provided by an embodiment of the present invention, which is applied to a first server, for example, the first server is an IoT management server; wherein the method may specifically include:

[0345] Step 701, sending first information to a terminal; the first information is used by the terminal to determine a target satellite to access;

[0346] The first information includes at least one of the following information:

[0347] Information related to satellite access;

[0348] Satellite coverage information;

[0349] ephemeris information;

[0351] Optionally, the information related to satellite access includes one or more of the following:

[0352] Satellite access method;

[0353] The type of satellite being accessed;

[0354] The satellite ID of the access;

[0357] In the satellite access method of an embodiment of the present invention, a first server sends first information related to satellite access to a terminal, and the first information is used by the terminal to determine a target satellite to access; the terminal is enabled to support application layer communication via satellite access, thereby meeting the communication needs between the terminal and the application server in scenarios such as remote mountainous areas, sea surfaces, and polar regions where there is no base station coverage.

[0358] As an optional implementation, the method of the embodiment of the present invention may further include:

[0359] receiving a first request sent by the terminal, where the first request is used to request reporting or updating terminal capability information, and the first request carries the terminal capability information;

[0360] Optionally, the terminal capability information includes one or more of the following information:

[0361] Identification of the servicing satellite;

[0362] Supported satellite access methods;

[0363] Supported satellite access types.

[0364] Here, the terminal capability information may also include: an identifier of the terminal (such as GPSI or group ID) and a device type, etc.

[0365] Specifically, when the first request is used to request reporting of terminal capability information, the first request may be a UE capability report request. When the first request is used to request updating of terminal capability information, the first request may be a UE capability update request. Here, the first request carries the terminal capability information.

[0366] After the terminal is authenticated, a first response is sent to the terminal, and the terminal capability information is stored or updated.

[0367] This implementation method illustrates that the terminal supports reporting and updating of terminal capabilities, and specifically supports reporting and updating of satellite access capabilities.

[0368] As an optional implementation, the method of the embodiment of the present invention may include:

[0369] receiving a second request sent by the terminal, where the second request is used to request access information required by the network;

[0370] Accordingly, the above step 701, sending the first information to the terminal, may include:

[0371] After the terminal is authenticated, a second response is sent to the terminal, where the second response includes the first information, and the first information is information related to satellite access queried through the first server.

[0372] This implementation method illustrates that the terminal can actively query the access information required by the network.

[0373] As an optional implementation, before step 701, the method of the embodiment of the present invention may further include:

[0374] 1. Receive a fifth request sent by the second server, where the fifth request is used to request the terminal to report information related to the target communication service;

[0375] Here, the second server may be an IoT vertical application server.

[0376] 2. Determine the first information according to the fifth request, the terminal capability information and the pre-configuration information, where the first information includes information related to satellite access.

[0377] It should be noted that the first server matches the information in the request with the terminal capability information and determines the first information in combination with the preconfigured information, for example, determines the appropriate access mode, and then sends the first information to the terminal, and the terminal subsequently reports the corresponding information according to the sent first information.

[0378] Further, the fifth request includes a terminal identifier, a terminal type, terminal area information, an information transmission delay, an information transmission interval, and a preset reporting condition;

[0379] Correspondingly, in the above steps, determining the first information according to the fifth request, the terminal capability information and the pre-configuration information includes at least one of the following:

[0380] Determining a satellite access mode of the terminal according to the area information of the terminal and the terminal capability information;

[0381] Determining satellite type information accessed by the terminal according to second information and the terminal capability information, wherein the second information includes the transmission delay and / or the information transmission interval;

[0382] The satellite identifier to be accessed by the terminal is determined according to the pre-configuration information and the terminal capability information.

[0383] Based on this implementation, correspondingly, the above step 701, sending the first information to the terminal, may include:

[0384] A third request is sent to the terminal, wherein the third request is used to request the terminal to report information related to the target communication service, and the third request includes a preset reporting condition and the first information.

[0385] Accordingly, the method of the embodiment of the present invention may further include:

[0386] A third response is received, which is sent by the terminal based on the first information when the preset reporting condition is met, wherein the third response includes information related to the target communication service.

[0387] Furthermore, the method of the embodiment of the present invention may also include:

[0388] A fifth response is sent to the second server, wherein the fifth response includes the information related to the target communication service.

[0389] In this implementation, the first server may select different first information (such as different access methods) based on different requests (such as the terminal reporting information related to the target communication service (different communication services)). Afterwards, the terminal may report information related to the target communication service based on the first information sent. In addition, the first server may also send information related to the target communication service to the second server, so that the server corresponding to the terminal application layer (i.e., the second server) can obtain information related to the target communication service on the terminal side.

[0390] Example 3: IoT management server selects different access methods based on different requests

[0391] After obtaining the access type supported by the terminal, if the IoT management server receives request information for the terminal from the IoT vertical application server, it can match the information in the request with the terminal capability information, and select the appropriate access method based on its own configuration, and send it to the terminal, requesting it to report the corresponding information according to the sent access method.

[0392] See also Figure 8 The specific implementation process is as follows:

[0393] 0) The IoT management client has sent terminal capability information to the IoT management server, including satellite access capabilities.

[0394] 1) The IoT vertical application server (IoT VAL server) initiates a request for certain IoT devices to the IoT management server, requesting the terminal to report information related to the target communication service. In this embodiment, the request is a terminal traffic reporting request.

[0395] For example, if these devices are requested to report their used traffic, the request information includes IoT device identification, device type, reporting area, reporting period, reporting delay, number of reports, triggering conditions (such as periodic reporting), etc.

[0396] 2) The IoT management server compares and analyzes the request initiated by the IoT vertical application server with the received terminal capability information and its own configuration information, and matches the terminal with the appropriate access method and type.

[0397] The matching methods include but are not limited to the following:

[0398] According to the terminal's regional information, the terminal can select satellite access;

[0399] Determine the type of satellite being accessed based on the information transmission delay and information transmission interval;

[0400] Determine the specific satellite to be accessed based on pre-configured information.

[0401] For example, the IoT management server determines that the terminal can choose satellite access based on the terminal's regional information, and determines the access satellite type or satellite ID based on information transmission delay, interval, and pre-configuration requirements.

[0402] For example: Prefer 3GPP access: Satellite (priority 1)

[0403] Preferred satellite type: GEO

[0404] Prefer 3GPP access: 5G NR (priority 2)

[0405] Dedicated 3GPP access: Satellite (Satellite ID)

[0406] 3) The IoT management server forwards the terminal traffic reporting request initiated by the IoT vertical application server to the IoT management client, and carries the information in step 1), including the reporting cycle, reporting delay, reporting quantity, triggering conditions, etc., and also carries the access method and access type recommended in step 2).

[0407] 4) The IoT management client receives and stores the terminal traffic reporting request. When the triggering conditions are met (such as periodic reporting), the terminal will report the information according to the access method and access type issued by the network in step 3).

[0408] 5) The IoT management client accesses the GEO satellite and sends its own traffic usage information within the required time period to the IoT management server.

[0409] 6) The IoT management server sends the received terminal traffic information to the IoT vertical application server.

[0410] As another optional embodiment, the method of the embodiment of the present invention may further include:

[0411] (1) receiving a fourth request sent by the terminal, where the fourth request is used to request a subscription to satellite coverage information of the terminal;

[0412] (2) obtaining ephemeris information and / or satellite coverage information through a non-ground network server;

[0413] Accordingly, the above step 701, sending the first information to the terminal, may include:

[0414] A fourth response is sent to the terminal, where the fourth response includes the first information, and the first information includes the ephemeris information and / or satellite coverage information.

[0415] Accordingly, the method of the embodiment of the present invention may further include:

[0416] An uplink message is received which is sent by the terminal within an available time for using a satellite to perform a corresponding communication service; wherein the available time is determined by the terminal based on the satellite coverage information.

[0417] It should be noted that when the first information received by the terminal only includes ephemeris information, the terminal infers the corresponding satellite coverage information based on the ephemeris information; based on the satellite coverage information, the terminal can determine the available time during which the terminal can use the satellite to perform corresponding communication services (such as surfing the Internet, making phone calls, etc.), that is, if the terminal is within the satellite coverage range and needs to initiate an uplink message, the corresponding uplink message is initiated within the available time as required.

[0418] Specifically, step (2) may include:

[0419] ① receiving a sixth request sent by the non-terrestrial network server, wherein the sixth request is one of a registration request, an update registration request and a deregistration request for satellite related information;

[0420] ② Based on the sixth request, obtain ephemeris information and / or satellite coverage information.

[0421] Furthermore, the method of the embodiment of the present invention may also include: sending a sixth response to the sixth request to the non-terrestrial network server.

[0422] In an optional embodiment, the registration request includes: one or more of: satellite identification, ephemeris information and satellite coverage information; accordingly, step ② may include:

[0423] In case the sixth request is the registration request, performing an authorization check on the non-terrestrial network server;

[0424] After determining that the non-terrestrial network server is authorized, if the registration request includes ephemeris information and / or satellite coverage information, the ephemeris information and / or the satellite coverage information is stored.

[0425] Furthermore, the method of the embodiment of the present invention may also include:

[0426] After obtaining the satellite coverage information, the satellite coverage information is formatted to obtain formatted satellite coverage information.

[0427] It should be noted that the first server will receive satellite coverage information sent by different non-ground network servers. In order to enable the core network equipment and terminals to efficiently identify the satellite coverage information, the first server will format the satellite coverage information and convert it into satellite coverage information in a unified format; then it will be sent to the core network equipment and terminals.

[0428] In another optional embodiment, step ② may include:

[0429] In case that the sixth request is the registration update request or the deregistration request, based on the sixth request, the locally stored ephemeris information and / or satellite coverage information is updated to obtain updated ephemeris information and / or satellite coverage information.

[0430] When the first server receives a registration update request or a deregistration request, it indicates that the previously locally stored ephemeris information and / or satellite coverage information needs to be updated; here, if it is a deregistration request, the ephemeris information and / or satellite coverage information of the corresponding satellite in the deregistration request needs to be deleted.

[0431] Example 4: Registration, update and deregistration process of non-terrestrial network server (also known as satellite control center)

[0432] The non-ground network server can initiate initial registration, registration update and deregistration requests to the IoT management server. Through the registration, update or deregistration process, the IoT management server can obtain the identification of a specific satellite, ephemeris information and coverage information of the satellite.

[0433] See also Fig. 9 The specific implementation process is as follows:

[0434] 0. The IoT management client has subscribed to satellite coverage information change messages from the IoT management server.

[0435] 1. The non-ground network server initiates a registration request to the IoT management server. The registration request contains satellite identification, ephemeris information, satellite coverage information, terminal information using the satellite, etc. The registration request type can be initial registration or registration update, etc.

[0436] 2. The IoT management server authorizes and checks whether the non-ground network server can initiate the corresponding registration request;

[0437] 3. If the authorization is passed, the IoT management server accepts the registration request from the non-ground network server and stores the information contained in the registration request.

[0438] The IoT management server can convert the satellite coverage information sent by different non-ground network servers into a unified format and send it to 3GPP core network devices and terminals.

[0439] If the non-ground network server only registers the ephemeris information, the IoT management server can infer the corresponding satellite coverage information based on the ephemeris information.

[0440] 4. The IoT management server sends the format-converted satellite coverage information to the IoT management client and 3GPP core network equipment. The IoT management client and 3GPP core network equipment store the received satellite coverage information and send a response.

[0441] It should be noted that after receiving the satellite coverage information, the terminal can determine the available time when the terminal can use the satellite for the corresponding communication service. That is, if the terminal is within the satellite coverage, if an uplink message needs to be initiated, it needs to initiate the corresponding uplink message within the available time as required.

[0442] 5. If some satellites are out of service, the non-ground network server initiates a deregistration request for these satellites to the IoT management server;

[0443] 6. The IoT management server accepts the request and deletes the stored satellite registration information, and sends a response to the non-ground network server.

[0444] 7. The IoT management server sends the updated satellite coverage information to the IoT management client. The IoT management client stores the received information and sends a response.

[0445] As an optional implementation manner, the first information is the subscription event for the terminal; before sending the first information to the terminal, the method of the embodiment of the present invention further includes:

[0446] The first information is obtained through a non-ground network server.

[0447] Specifically, obtaining the first information through the non-ground network server may include:

[0448] Receiving a subscription request for satellite-related information sent by the non-terrestrial network server;

[0449] After the non-terrestrial network server is authenticated, the first information included in the subscription request is obtained.

[0450] The subscription request includes the subscribed satellite identifier, the terminal identifier, subscription events for the terminal (such as the number, speed or movement trajectory of terminals accessing a certain satellite, the delay of the satellite as a return trip, etc.), triggering conditions (such as the reporting time point), etc.

[0451] Here, after obtaining the first information, step 701 is performed; accordingly, the method of the embodiment of the present invention may include:

[0452] A first subscription event report sent by the terminal is received, where the first subscription event report is generated by the terminal when the subscription event for the terminal meets a first preset subscription condition.

[0453] As an optional implementation, the subscription request also includes a subscription event for a core network device; and the method of the embodiment of the present invention further includes:

[0454] Sending a monitoring request to the core network device, wherein the monitoring request is used to request monitoring of subscription events for the core network device and the terminal;

[0455] Receive third information sent by the core network device, the third information including a second subscription event report; wherein the second subscription event report includes information generated by the core network device when the subscription event for the core network device and the terminal meets a second preset subscription condition.

[0456] Furthermore, the method of the embodiment of the present invention may also include:

[0457] Integrate the target information and the third information to obtain integrated information;

[0458] Sending the integrated information to a non-terrestrial network server, wherein the target information includes at least one of the following:

[0459] Information related to the target communication service;

[0460] Uplink message;

[0461] First subscribe to incident reports.

[0462] It should be noted that the first server collects satellite management information through operation, maintenance and management of OAM interface configuration and interaction with the core network device.

[0463] Example 5: Non-terrestrial network server initiates subscription service

[0464] The non-ground network server can initiate a subscription request for the satellite and the terminals used on the satellite to the IoT management server, and can subscribe to the terminal and network information using the satellite, such as the number of terminals using the satellite, the latency of the satellite as a backhaul, etc.

[0465] See also Fig.10 The specific implementation process is as follows:

[0466] 1. The non-ground network server initiates a subscription request for satellite-related information to the IoT management server, including the subscribed satellite ID, UE ID, subscribed events (such as the number of terminals accessing a certain satellite, the speed or movement trajectory, the delay of the satellite as backhaul, etc.), triggering conditions (such as the reporting time point), etc.

[0467] 2a. The IoT management server authenticates the subscription message initiated by the non-terrestrial network server. If the authentication is successful, the IoT management server initiates a capability exposure monitoring request to the 3GPP core network device (5GC or EPC), requesting to monitor the events subscribed in step 1, such as the number and rate of terminals accessing a certain satellite, and carrying the corresponding identification and triggering conditions;

[0468] Optionally, 2b, the IoT management server may also initiate a subscription event for the subscribed terminal, such as the rate of the terminal accessing a certain satellite, and carry the corresponding identifier and trigger condition;

[0469] Optionally, 3. The IoT management client accepts the subscription request and sends a subscription request response.

[0470] 4. The IoT management server sends a subscription request response to the non-terrestrial network server.

[0471] 5. Subscription conditions are met.

[0472] If the trigger reporting time required in step 1 has arrived, the 3GPP core network device and the IoT management client will report the subscription event report.

[0473] 6a. The 3GPP core network device sends the collected data to the IoT management server.

[0474] Optionally, 6b, the IoT management client also reports the collected data to the IoT management server.

[0475] Here, the collected data may be a subscription event report.
