Negotiation method and apparatus therefor

A negotiation method, performed by a user equipment (UE), comprising:

• sending a UE capability indication of the UE for a satellite access to a network device;
• and
• receiving network indication information sent by the network device, wherein the network indication information comprises any one of:
• first indication information, indicating that the network device supports a discontinuous coverage for the satellite access;
• second indication information, indicating that the UE provides a power-saving parameter and a non-access stratum (NAS) timer;
• third indication information, indicating that the UE provides satellite coverage information related to the UE;
• fourth indication information, indicating a first time range or a first timer for a random communication;
• or
• fifth indication information, indicating a second time range for a delayed communication.

A communication device, comprising:

• a processor;
• and
• a memory, configured to store a computer program executable by the processor,
• wherein the processor is configured to execute the computer program to cause the communication device to:
• receive a user equipment (UE) capability indication of a UE for a satellite access, and provide network indication information to the UE based on the UE capability indication,
• wherein the UE capability indication of the UE for the satellite access indicates at least one capability selected from the group of capabilities including:
• supporting a discontinuous coverage for the satellite access;
• supporting sending a power-saving parameter and a non-access stratum (NAS) timer;
• supporting sending satellite coverage information related to the UE;
• supporting a random communication before an imminent loss of a satellite coverage;
• or
• supporting a delayed communication after a restoration of a satellite coverage.
