Abstract
A session handling method and apparatus, where the method includes: initiating, by a terminal, an application (APP); determining a session type of a packet data unit (PDU) session based on the APP; and sending a first message to an access and mobility management function (AMF) entity, where the first message includes the session type, and the first message is used to request to establish the PDU session of the session type. In the method, a network side can establish the PDU session of the corresponding type based on the session type of the PDU session that is sent by the terminal, in order to establish the PDU session of the correct type for the terminal.
Claims20
A session handling method comprising:
- receiving, by a terminal, a user equipment (UE) route selection policy (URSP) from a network, wherein the URSP comprises:
- a traffic filter, direct offload information, slice information, continuity types, a data network (DN) identifier, an access type, and a first session type, wherein the traffic filter includes a first application (APP), and wherein the first session type is an Ethernet type;
- initiating, by the terminal, the first APP;
- determining, by the terminal, the Ethernet type associated with the first APP based on the URSP;
- sending, by the terminal, a first message to an access and mobility management function entity, wherein the first message comprises the Ethernet type, and wherein the first message requests to establish a first session of the Ethernet type;
- receiving, by the terminal, a session reject message from a session management function entity, wherein the session reject message comprises a second session type determined by the session management function entity, and wherein the second session type is different from the Ethernet type;
- and
- sending, by the terminal, a third message to the access and mobility management function entity, wherein the third message comprises the second session type, and wherein the third message requests to establish a second session of the second session type.
An apparatus comprising:
- a memory storage configured to store instructions;
- and
- one or more processors in communication with the memory storage and configured to execute the instructions to:
- receive a user equipment (UE) route selection policy (URSP) from a network, wherein the URSP comprises:
- a traffic filter, direct offload information, slice information, continuity types, a data network (DN) identifier, an access type, and a first session type, wherein the traffic filter includes a first application (APP), and wherein the first session type is an Ethernet type;
- initiate the first APP;
- determine the Ethernet type associated with the first APP based on the URSP;
- send a first message to an access and mobility management function entity, wherein the first message comprises the Ethernet type, and wherein the first message requests to establish a first session of the Ethernet type;
- receive a session reject message from a session management function entity, wherein the session reject message comprises a second session type determined by the session management function entity, and wherein the second session type is different from the first session type;
- and
- send a third message to the access and mobility management function entity, wherein the third message comprises the second session type, and wherein the third message requests to establish a second session of the second session type.
