Abstract

The invention discloses a session establishment method and a session establishment device, which are used for solving the problem that a 4G network establishment control plane data transmission methodin the prior art is not suitable for a 5G network. According to the embodiment of the invention, after receiving a session establishment request sent by a terminal, an access and mobility managementfunctional entity indicates to establish a control plane session for the terminal to the session management functional entity; and the session management function entity indicates the tunnel information of downlink data transmission to the user plane function entity, and when data transmission is needed, the access and mobility management function entity and the terminal perform data transmissionthrough a non-access layer message. Due to the fact that when data needs to be transmitted, data transmission is carried out between the access and mobility management function entity and the terminalthrough the non-access layer message, and the method and the device are suitable for transmission of control plane data in a 5G network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for establishing a session. Background technique [0002] In order to support the small data transmission of CIoT (Cellular Internet of Things, Cellular Internet of Things) applications such as water meters and electricity meters, 3GPP (3rd Generation Partnership Project, the third generation mobile communication standardization organization) defined a Control Plane (control plane session) in R13 ) data transmission method, which transmits data between the terminal and MME (Mobility Management Entity, mobility management entity) through NAS (Non Access Stratum, non-access stratum) messages, and does not establish an air interface DRB (Data Radio Bearer, data radio bearer) and S1-U connection. [0003] Compared with the 4G network architecture, the 5G network architecture has undergone major changes, mainly reflected in: (1), the network architecture bas...
