Communication method and apparatus

A communication method, comprising:

• sending, by an access network device, first indication information to a terminal device, wherein the first indication information indicates the terminal device to notify a network when the terminal device is about to leave a satellite service range;
• and
• receiving, by the access network device, second indication information from the terminal device, wherein the second indication information indicates that the terminal device is about to leave the satellite service range or is used to request to use a power saving mode, wherein
• the terminal device accesses the network through a satellite, and cannot access the network through the satellite within first duration after the terminal device leaves the satellite service range.

A communication apparatus, comprising at least one processor and one or more memories coupled to the at least one processor, wherein the one or more memories store programming instructions for execution by the at least one processor to perform operations comprising:

• receiving, by a terminal device, first indication information, wherein the first indication information indicates the terminal device to notify a network when the terminal device is about to leave a satellite service range;
• determining, by the terminal device, that the terminal device is about to leave the satellite service range;
• and
• sending, by the terminal device, second indication information, wherein the second indication information indicates that the terminal device is about to leave the satellite service range or is used to request to use a power saving mode, wherein
• the terminal device accesses the network through a satellite, and cannot access the network through the satellite within first duration after the terminal device leaves the satellite service range.
