Abstract
Embodiments of the present disclosure disclose a mobility management method, apparatus, and system, and pertain to the field of wireless communications technologies. The method includes: determining, by a first mobility management entity based on information about a PDN connection established by user equipment in a 4G network, a network slice corresponding to the PDN connection, and then determining, with reference to a subscribed network slice of the user equipment, a network slice allowed for the user equipment.
Claims20
A mobility management method, wherein the method comprises:
- obtaining, by a first mobility management entity, an identifier of a session management function entity corresponding to an established Packet Data Network (PDN) connection of user equipment (UE);
- obtaining, by the first mobility management entity based on the identifier of the session management function entity, information about a network slice corresponding to the established PDN connection from the session management function entity;
- and
- obtaining, by the first mobility management entity based on the information about the network slice corresponding to the established PDN connection, information about a network slice allowed for the UE.
An apparatus comprising:
- at least one processor;
- and
- at least one memory coupled to the at least one processor and storing program instructions for execution by the at least one processor, cause the apparatus to:
- obtain an identifier of a session management function entity corresponding to an established Packet Data Network (PDN) connection of user equipment (UE);
- obtain, based on the identifier of the session management function entity, information about a network slice corresponding to the established PDN connection from the session management function entity;
- and
- obtain, based on the information about the network slice corresponding to the established PDN connection, information about a network slice allowed for the UE.
A mobility management method, wherein the method comprises:
- obtaining, by a first mobility management entity, an identifier of a session management function entity corresponding to an established Packet Data Network (PDN) connection of user equipment (UE);
- sending, by the first mobility management entity based on the identifier of the session management function entity, a request message for obtaining network slice corresponding to the PDN connection to the session management function entity;
- receiving, by the session management function entity, the request message from the first mobility management entity;
- in response to the request message, sending, by the session management function entity, a response message to the first mobility management entity, wherein the response message comprises information about the network slice corresponding to the established PDN connection;
- receiving, by the first mobility management entity, the response message from the session management function entity;
- and
- obtaining, by the first mobility management entity based on the information about the network slice corresponding to the established PDN connection, information about a network slice allowed for the UE.
