The method includes: receiving the NAS request of a terminal device and at least two tracking area identities for the terminal device from a second network device and accepting the NAS request. ## Claims ### Claim 1 A method of wireless communication of a first network device, comprising: receiving, by the first network device, a Non-access stratum (NAS) request of a terminal device and at least two tracking area identities (TAIs) for the terminal device from a second network device, each of the at least two TAIs corresponding to a tracking area code (TAC) associated with a satellite; and accepting, by the first network device, the NAS request, wherein the receiving, by the first network device, the NAS request of the terminal device and the at least two TAIs for the terminal device from the second network device comprises: receiving, by the first network device, an N2 message from the second network device, the N2 message carrying the NAS request and user location information (ULI), and the ULI carrying the at least two TAIs for the terminal device, and wherein the first network device is an Access and Mobility Management Function (AMF), and the second network device is a base station. ### Claim 2 (depends on 1) The method of claim 1, wherein: one of the at least two TAIs is a TAI corresponding to a tracking area (TA) where the terminal device is located, and the TA is determined by the second network device. ### Claim 3 (depends on 1) The method of claim 1, wherein: a tracking area (TA) corresponding to any of the at least two TAIs is an area allowing the terminal device to initiate a service, or a TA corresponding to at least one of the at least two TAIs is an area allowing the terminal device to initiate a service. ### Claim 4 (depends on 3) The method of claim 3, wherein the TA in which the terminal device is located is the area allowing the terminal device to initiate the service. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving, by the first network device, a tracking area identity (TAI) of a tracking area (TA), in the (TAIs), where the terminal device is located from the second network device, wherein the TA where the terminal device is located is determined by the second network device. ### Claim 6 A first network device, comprising: a processor; and memory storing instructions, which when executed by the processor, cause the processor to: receive a Non-access stratum (NAS) request of a terminal device and at least two tracking area identities (TAIs) for the terminal device from a second network device, each of the at least two TAIs corresponding to a tracking area code (TAC) associated with a satellite; and accept the NAS request, wherein the memory storing instructions, which when executed by the processor, further cause the processor to: receive an N2 message from the second network device, the N2 message carrying the NAS request and user location information (ULI), and the ULI carrying the at least two TAIs, and wherein the first network device is an Access and Mobility Management Function (AMF), and the second network device is a base station. ### Claim 7 (depends on 6) The first network device of claim 6, wherein: one of the at least two TAIs is a TAI corresponding to a tracking area (TA) where the terminal device is located, and the TA is determined by the second network device. ### Claim 8 (depends on 6) The first network device of claim 6, wherein: a TA corresponding to any of the at least two TAIs is an area allowing the terminal device to initiate a service, or a TA corresponding to at least one of the at least two TAIs is an area allowing the terminal device to initiate a service. ### Claim 9 (depends on 8) The first network device of claim 8, wherein the TA where the terminal device is located is the area allowing the terminal device to initiate the service. ### Claim 10 (depends on 6) The first network device of claim 6, wherein the memory storing instructions, which when executed by the processor, further cause the processor to: receive a TAI of a TA, in the TAIs, where the terminal device is located from the second network device, the TA where the terminal device is located being determined by the second network device. ### Claim 11 A second network device, comprising: a processor; and memory storing instructions, which when executed by the processor, cause the processor to: receive a Non-access stratum (NAS) request from a terminal device; and transmit the NAS request and at least two tracking area identities (TAIs) for the terminal device to a first network device, each of the at least two TAIs corresponding to a tracking area code (TAC) associated with a satellite, wherein the memory storing instructions, which when executed by the processor, further cause the processor to: transmit an N2 message to the first network device, the N2 message carrying the NAS request and user location information (ULI), and the ULI carrying the at least two TAIs, and wherein the first network device is an Access and Mobility Management Function (AMF), and the second network device is a base station. ### Claim 12 (depends on 11) The second network device of claim 11, wherein: one of the at least two TAIs is a TAI corresponding to a tracking area (TA) where the terminal device is located, and the TA is determined by the second network device. ### Claim 13 (depends on 11) The second network device of claim 11, wherein: a TA corresponding to any of the at least two TAIs is an area allowing the terminal device to initiate a service, or a TA corresponding to at least one of the at least two TAIs is an area allowing the terminal device to initiate a service. ### Claim 14 (depends on 13) The second network device of claim 13, wherein the TA where the terminal device is located is the area allowing the terminal device to initiate the service. ### Claim 15 (depends on 11) The second network device of claim 11, wherein the memory storing instructions, which when executed by the processor, further cause the processor to: transmit a TAI of a TA, in the TAIs, where the terminal device is located to the first network device, the TA where the terminal device is located being determined by the second network device.
