Satellite-based communication method and apparatus, computer-readable medium, and electronic device

An electronic device in a spaceborne base station deployed on a first satellite and having established a service link with a user equipment, the electronic device comprising:

• one or more processors;
• and
• a memory, configured to store one or more computer programs, the one or more computer programs, when executed by the one or more processors, causing the electronic device to implement a satellite-based communication method including:
• establishing a plurality of communication links between the spaceborne base station and core network elements;
• in response to a service request from the user equipment via the service link, communicating with the core network elements by using a first communication link in the plurality of communication links;
• and
• when the first communication link is abnormal, communicating with the core network elements by using a second communication link in the plurality of communication links.

A non-transitory computer-readable medium, having a computer program stored therein, the computer program, when executed by a processor of an electronic device in a spaceborne base station deployed on a first satellite and having established a service link with a user equipment, causing the electronic device to implement a satellite-based communication method including:

• establishing a plurality of communication links between the spaceborne base station and core network elements;
• in response to a service request from the user equipment via the service link, communicating with the core network elements by using a first communication link in the plurality of communication links;
• and
• when the first communication link is abnormal, communicating with the core network elements by using a second communication link in the plurality of communication links.
