determining, by the terminal management function entity, a service processing for the terminal device based on the first indication information; and
transmitting, by the terminal management function entity, second indication information indicating the service processing to a session management function entity,
wherein the service processing comprises deleting one or more service data flows of the terminal device, and the one or more service data flows are identified through at least one of an IP-5 tuple, an IP-3 tuple, or an application identifier.
2. The method according to claim 1 , wherein the service processing further comprises at least one of:
deleting a Protocol Data Unit (PDU) session of one IP address or PDU sessions of multiple IP addresses of the terminal device,
routing data in a PDU session of one IP address or PDU sessions of multiple IP addresses of the terminal device to a server or another terminal device, or
routing data of one or more service data flows of the terminal device to a server or another terminal device.
3. The method according to claim 1 , wherein the first area is a Tracking Area (TA) list or a cell list in a 3 GPP network, geographic position information, a postal code area or an administrative area.
4. The method according to claim 1 , wherein
the terminal device is an Unmanned Aerial Vehicle (UAV) device, and
the terminal management function entity is a UAV management entity.
5. A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program causes a computer to perform the wireless communication method according to claim 1 .
6. The non-transitory computer-readable storage medium according to claim 5 , wherein the first area is a Tracking Area (TA) list or a cell list in a 3 GPP network, geographic position information, a postal code area or an administrative area.
7. A wireless communication method, comprising:
receiving, by a session management function entity from a terminal management function entity in a core network, second indication information indicating a service processing for the terminal device, the service processing being determined by the terminal management function entity based on first indication information received from a mobility management function entity, the first indication information indicating moving of a terminal device into or out of a first area, and the mobility management function entity being an Access and Mobility Management Function (AMF) entity; and
performing, by the session management function entity, the service processing on the terminal device based on the second indication information received from the terminal management function,
wherein the service processing comprises deleting one or more service data flows of the terminal device, and the one or more service data flows are identified through at least one of an IP-5 tuple, an IP-3 tuple, or an application identifier.
8. The method according to claim 7 , wherein the service processing further comprises at least one of:
deleting a Protocol Data Unit (PDU) session of one IP address or PDU sessions of multiple IP addresses of the terminal device,
routing data in a PDU session of one IP address or PDU sessions of multiple IP addresses of the terminal device to a server or another terminal device, or
routing data of one or more service data flows of the terminal device to a server or another terminal device.
9. A network device, comprising:
a memory having a computer program stored thereon; and
a processor configured to invoke and execute the computer program stored in the memory to perform the wireless communication method according to claim 7 .
10. The network device according to claim 9 , wherein the service processing further comprises at least one of:
deleting a Protocol Data Unit (PDU) session of one IP address or PDU sessions of multiple IP addresses of the terminal device,
routing data in a PDU session of one IP address or PDU sessions of multiple IP addresses of the terminal device to a server or another terminal device, or
routing data of one or more service data flows of the terminal device to a server or another terminal device.
11. A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program causes a computer to perform the wireless communication method according to claim 7 .
12. The method according to claim 7 , wherein the first area is a Tracking Area (TA) list or a cell list in a 3 GPP network, geographic position information, a postal code area or an administrative area.
13. The method according to claim 7 , wherein the terminal device is an Unmanned Aerial Vehicle (UAV) device, and the terminal management function entity is a UAV management entity.
14. The network device according to claim 9 , wherein the first area is a Tracking Area (TA) list or a cell list in a 3 GPP network, geographic position information, a postal code area or an administrative area.
15. The network device according to claim 9 , wherein the terminal device is an Unmanned Aerial Vehicle (UAV) device, and the terminal management function entity is a UAV management entity.
16. A network device, comprising:
a memory having a computer program stored therein; and
a processor configured to invoke and execute the computer program stored in the memory to:
receive first indication information transmitted by a mobility management function entity in a core network, the first indication information indicating moving of a terminal device into or out of a first area, the mobility management function entity being an Access and Mobility Management Function (AMF) entity;
determine a service processing for the terminal device based on the first indication information; and
