[0081] Furthermore, the disclosed method opens up a new direction for performance improvement based on the original satellite-to-ground communication technology, providing possibilities for simple and efficient communication processes in the future.

[0082] In some embodiments of the present disclosure, the processing functions of a satellite supporting a general architecture for regenerative payloads may also include any one or more of the following functions: information collection function, information processing function, information receiving function, information sending function, and information query function.

[0083] By equipping satellites with various differentiated on-board processing functions, information discovery and collection between satellites and the ground, and long-distance communication between satellites can be achieved, thereby improving the integrated air-space-ground system and enhancing the system's service quality.

[0140] In some embodiments, step S904 is equivalent to step S720.

[0141] In step S906, the user terminal 900a sends a service request to the satellite 900b.

[0142] In some embodiments, step S906 is equivalent to step S810.

[0147] 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.

[0148] In some embodiments, step S910 is equivalent to step S860.

[0149] In step S912, the satellite 900c sends a service response to the satellite 900b.

[0150] In some embodiments, step S912 is equivalent to step S870.

[0151] In step S914, the satellite 900b forwards the service to the user terminal 900a.

This is similar to method 300 in FIG. 3 and will not be further described here.

[0165] In some embodiments of the present disclosure, step S1010 may further include: the second-type satellite receiving, using an information receiving function, a service information list periodically transmitted by the first-type satellite; the second-type satellite integrating, using an information processing function, all received service information lists to obtain a service information summary list; and the second-type satellite transmitting, using an information transmitting function, the service information summary list to the first-type satellite, thereby sharing the service information summary list with the first-type satellite.
