[0116] In step S720, the first type of satellite broadcasts an announcement message to user terminals within its beam coverage area through an information sending function, wherein the announcement message includes service information, so that the user terminal selects a target service from the service information according to its own needs to realize service discovery.

[0117] In some embodiments of the present disclosure, the announcement message may also include one or more of the following information: the type of discovery message, application code or restriction code, metadata information of the application layer and the corresponding satellite identification, relay indication, and security protection elements.

[0137] In step S906, the user terminal 900a sends a service request to the satellite 900b.

[0138] In some embodiments, step S906 is equivalent to step S810.

[0143] Among them, satellite 900b does not support the Internet service currently requested by the terminal, while satellite 900c is a target service satellite that supports the Internet service currently requested by the terminal.

[0144] In some embodiments, step S910 is equivalent to step S860.

[0153] In step S1020, the satellite of the specific type assists the user terminal in establishing a communication link according to the satellite information.

[0154] The embodiments of the present disclosure address the technical problem that there is no disclosure in the related art that ground user terminals can communicate with other terminals through information interaction between satellites. A terminal communication method in an air-ground integration scenario is designed, and a method for coordinating resources between various types of satellites is realized through a satellite's general architecture for supporting regenerative payloads, providing an interaction mechanism for the business resources of each node in the satellite Internet, and further improving the communication performance of the air-ground integration system.

[0166] There may be one or more user terminals within the coverage area of ​​the first type of satellite beam.

[0167] The method of the disclosed embodiment is aimed at the current technical status that the satellite Internet composed of multiple types of satellites lacks a mechanism for sharing information resources and a public terminal discovery process, and the role of the satellite is limited to the transparent forwarding function, resulting in a complex communication process, high redundancy, high latency, and high system energy consumption. The method of discovering user terminals by broadcasting through satellites and receiving responses from user terminals can improve the efficiency of terminal discovery and save energy consumption of satellite systems.

[0170] In step S1204, the first type of satellite determines whether it covers the target user terminal.

[0171] The first type of satellite determines whether it covers the target user terminal through an information query function.

[0172] In step S1206, if the first type of satellite determines that the target user terminal is within its coverage, it assists the user terminal in establishing a communication link.

[0173] In step S1208, if the first type of satellite determines that the target user terminal is not within its coverage, the target communication satellite covering the target user terminal is searched in the shared service information summary list through the information query function. The target communication satellite may be a first type of satellite.

[0174] In step S1210, the first type of satellite assists the user terminal in establishing a communication link via the target communication satellite.

[0175] The method of the disclosed embodiment reduces the complexity of satellite-assisted user terminal communication, and by processing different situations through a judgment mechanism, makes satellite system-assisted user terminal communication more convenient, and solves the conflict problem between satellite directly assisting user terminal communication and providing relay services for user terminals.

[0189] In some embodiments, step S1304 and step S1306 are equivalent to step S1120.

[0190] In step S1308, the satellite 1300b receives the communication request sent by the user terminal 1300a.

[0194] In other embodiments, if the satellite 1300b determines that the destination terminal called by the user terminal 1300a is within its coverage area, it assists the user terminal 1300a in establishing a communication link.

[0195] In step S1312, satellite 1300b sends a connection request to satellite 1300c.

[0196] In some embodiments, step S1312 is equivalent to step S1212.

[0205] In summary, based on the terminal discovery technology between the satellite and the ground, ground users can achieve long-distance communication through satellites. When a ground user has a communication request, it sends a communication request to the near-ground satellite as the source terminal. The near-ground satellite analyzes the calling signaling in the communication request, finds the near-ground satellite covering the destination terminal and sends a connection request to it. The near-ground satellite on the destination terminal side determines the satellite beam number corresponding to the destination terminal based on the connection request, thereby completing the long-distance link connection from the calling terminal to the called terminal on the ground.
