US 10,834,208 B2 · User device determines whether to create a new session based on session type information

Abstract

A session processing method related to the field of wireless communications technologies is provided. The method discloses: obtaining, by user equipment (UE), session type information, where the session type information is used to indicate a type of a first session; and when a first application triggers a first service, determining, by the UE based on the session type information, whether a create session request needs to be initiated for the first service. According to the solutions provided in embodiments, before the create session request is initiated, the UE may determine whether to reuse a created session or create a new session. In this way, for a service that can reuse a created session, no new session needs to be created, thereby reducing signaling exchange between the UE and a network side.

Dependent claims

A session processing method comprising:

obtaining, by user equipment (UE), session type information, wherein the session type information indicates a type of a first session, the session type information comprises a data network name (DNN), supported by the first session, and the session type information further comprises at least one of a type of a service supported by the first session and a type of a slice supporting the first session;
and
in response to a first application triggering a first service, determining, by the UE based on the session type information, whether a create session request needs to be initiated for the first service.

A communication device comprising:

a receiver, configured to cooperate with a processor to obtain session type information, wherein the session type information indicates a type of a first session, the session type information comprises a data network name (DNN), supported by the first session, and the session type information further comprises at least one of a type of a service supported by the first session and a type of a slice supporting the first session;
and
the processor, configured to:
in response to a first application triggering a first service, determine, based on the session type information, whether a create session request needs to be initiated for the first service.

1 more element

A session processing system comprising:

a user equipment (UE) and a session management function (SMF) device, wherein
the SMF device, is configured to send a create session response message to the UE, wherein the create session response message carries a session type information, the session type information indicates a type of a first session, the session type information comprises a data network name (DNN) supported by the first session, and the session type information further comprises at least one of a type of a service supported by the first session and a type of a slice supporting the first session;
the UE is configured to receive the create session response message, and in response to a first application triggering a first service, determine based on the session type information, whether a create session request needs to be initiated for the first service.
