Abstract
Embodiments of the present application provide user equipment (UE), a first core network entity, and a second core network entity, the first core network entity executes steps that include: establishing a signaling connection to the UE; receiving network slice information and a non-access stratum NAS message that are sent by the UE over the signaling connection; determining a target network slice from the at least one network slice based on the network slice information, wherein the target network slice comprises a second core network entity, and the UE performs NAS communication with the second core network entity by using the RAN and the first core network entity; and sending the NAS message to the second core network entity.
Claims24
User equipment (UE), comprising:
- a transceiver;
- a memory storing one or more instructions;
- and
- a processor coupled to the transceiver and the memory and configured to execute the one or more instructions to cause the UE to:
- establish a signaling connection to a first core network entity of a communications system that comprises the first core network entity, a radio access network (RAN), the UE, and at least one network slice;
- and
- send, using the transceiver, network slice information and a first non-access stratum (NAS) container to the first core network entity, wherein the first NAS container includes a first NAS message and the network slice information enables the first core network entity to determine a target network slice from the at least one network slice based on the network slice information, and wherein the UE performs NAS communication with a second core network entity in the target network slice using the RAN and the first core network entity.
A wireless communication method implemented by user equipment (UE), wherein the wireless communication method comprises:
- establishing a signaling connection to a first core network entity of a communications system that comprises the first core network entity, a radio access network (RAN), the UE, and at least one network slice;
- and
- sending network slice information and a first non-access stratum (NAS) container to the first core network entity, wherein the first NAS container includes a first NAS message and the network slice information enables the first core network entity to determine a target network slice from the at least one network slice based on the network slice information, and wherein the UE performs NAS communication with a second core network entity in the target network slice using the RAN and the first core network entity.
A non-transitory computer readable medium comprising computer-executable instructions, wherein the computer-executable instructions, when executed by a processor, cause a user equipment (UE) to:
- establish a signaling connection to a first core network entity of a communications system that comprises the first core network entity, a radio access network (RAN), the UE, and at least one network slice;
- and
- send network slice information and a first non-access stratum (NAS) container to the first core network entity, wherein the first NAS container includes a first NAS message and the network slice information enables the first core network entity to determine a target network slice from the at least one network slice based on the network slice information, and wherein the UE performs NAS communication with a second core network entity in the target network slice using the RAN and the first core network entity.
