Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application.

[0053] The term "and / or" in this article is only an association relationship describing associated objects, which means that there may be three kinds of relationships. situation.

[0054] figure 1 Shown is a possible network architecture diagram of the embodiment of the present application.

[0055] Terminal equipment can be called user equipment (user equipment, UE), mobile station (mobile station, MS), mobile terminal equipment (mobile terminal) or terminal equipment in the future 5G network. The radio access network (RAN) communicates with one or more core networks (such as network slices), and can also communicate with another terminal device, such as Device to Device (Device to Device, D2D) or Machine to Machine (Machine to Machine, M2M) scenarios. For example, the terminal device c...

Abstract

The present application relates to the field of wireless communication technologies, and in particular to a session context processing method, network element and terminal device, including: the session management network element receives the first message from the mobility management network element, and requests to establish a session for the terminal device, the The first message carries the identifier of the data network; the session management network element obtains the capability information of the data network according to the identifier of the data network; when the capability information of the data network is that the data network supports a non-IP type session , the session management network element generates a non-IP type session context according to the Ethernet type or unstructured type session context of the terminal device.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a session context processing method, network element and terminal equipment in a wireless communication system. Background technique [0002] The Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) standard defines that the fifth generation (5th Generation, 5G) network can support four types of packet data unit (Packet DataUnit, PDU) sessions, including IPv4 type, IPv6 Type, Ethernet (Ethernet) type, and non-structural (unstructured) type. However, in a fourth generation (4th Generation, 4G) network, two types of packet data unit sessions can be supported, including an IP type and a non-IP (Non-IP) type. [0003] The 3GPP standard currently stipulates that in the handover scenario from 5G to 4G network, if the terminal device establishes an Ethernet-type PDU session in the 5G network, then when the terminal device switch...
