Abstract
Embodiments of this application provide a message identification method and apparatus. The method includes: receiving, by user equipment UE, a paging message sent by an access network device; determining, by the UE, a core network entity to which the paging message belongs in a plurality of core network entities serving the UE; and establishing, by the UE, a data connection to the core network entity to which the paging message belongs. According to the message identification method and apparatus provided in the embodiments of this application, the UE can connect to different core network entities.
Claims9
A method of message identification, comprising:
- receiving, by a user equipment (UE), a paging message from an access network device at a paging occasion, wherein the paging occasion corresponds to a time-frequency resource;
- identifying, by the UE, based on the time-frequency resource, a core network entity to which the paging message belongs, wherein identifying the core network entity to which the paging message belongs based on the time-frequency resource comprises:
- distinguishing between whether the paging message belongs to an Evolved Packet Core (EPC) network entity and whether the paging message belongs to a Next Generation Core (NG-Core) network entity based on whether the paging message was received at a first paging occasion corresponding to the EPC network entity or whether the paging message was received at a second paging occasion corresponding to the NG-Core network entity, respectively, wherein in case that the paging message was received at the first paging occasion corresponding to the EPC network entity, the identified core network entity is the EPC network entity, and in case that the paging message was received at the second paging occasion corresponding to the NG-Core network entity, the identified core network entity is the NG-Core network entity;
- and
- establishing, by the UE, a data connection to the core network entity to which the paging message belongs.

A message identification apparatus, comprising:
- a non-transitory memory having instructions stored thereon;
- and
- a processor configured to execute the instructions, wherein execution of the instructions by the processor facilitates the following being performed by the message identification apparatus:
- receiving a paging message from an access network device at a paging occasion, wherein the paging occasion corresponds to a time-frequency resource;
- identifying, based on the time-frequency resource, a core network entity to which the paging message belongs, wherein identifying the core network entity to which the paging message belongs based on the time-frequency resource comprises:
- distinguishing between whether the paging message belongs to an Evolved Packet Core (EPC) network entity and whether the paging message belongs to a Next Generation Core (NG-Core) network entity based on whether the paging message was received at a first paging occasion corresponding to the EPC network entity or whether the paging message was received at a second paging occasion corresponding to the NG-Core network entity, respectively, wherein in case that the paging message was received at the first paging occasion corresponding to the EPC network entity, the identified core network entity is the EPC network entity, and in case that the paging message was received at the second paging occasion corresponding to the NG-Core network entity, the identified core network entity is the NG-Core network entity;
- and
- establishing a data connection to the core network entity to which the paging message belongs.
5 more elements
A system, comprising:
- a user equipment (UE);
- and
- an access network device;
- wherein the UE is configured to:
- receive a paging message from the access network device at a paging occasion, wherein the paging occasion corresponds to a time-frequency resource;
- and
- identify, based on the time-frequency resource, a core network entity to which the paging message belongs, wherein identifying the core network entity to which the paging message belongs based on the time-frequency resource comprises:
- distinguishing between whether the paging message belongs to an Evolved Packet Core (EPC) network entity and whether the paging message belongs to a Next Generation Core (NG-Core) network entity based on whether the paging message was received at a first paging occasion corresponding to the EPC network entity or whether the paging message was received at a second paging occasion corresponding to the NG-Core network entity, respectively, wherein in case that the paging message was received at the first paging occasion corresponding to the EPC network entity, the identified core network entity is the EPC network entity, and in case that the paging message was received at the second paging occasion corresponding to the NG-Core network entity, the identified core network entity is the NG-Core network entity;
- and
- wherein the access network device is configured to:
- allocate, based on the core network entity to which the paging message belongs, the time-frequency resource to the UE for receiving the paging message;
- send the paging message to the UE on the allocated time-frequency resource;
- receive a non-access stratum (NAS) message from the UE based on the paging message;
- determine a core network entity associated with the NAS message out of a plurality of core network entities of the access network device;
- and
- send the NAS message to the core network entity associated with the NAS message.
