Embodiment Construction

[0103] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0104] Before explaining and describing the embodiments of the present invention in detail, the application scenarios involved in the embodiments of the present invention are firstly introduced.

[0105] Currently, a terminal device can access a network through a 3GPP technology, or can access a network through a non-3GPP technology. Among them, 3GPP technology refers to the air interface technology formulated by 3GPP standards. For example, the air interface access technology of our commonly used 3G, 4G and 5G networks is 3GPP technology. The remaining air interface access technologies that are not formulated by the 3GPP standards are non-3GPP technologies. For example, an air interface technology represented by a Wireless Fide...

Abstract

The present application discloses a method and a device for acquiring an identity of a terminal device, which belong to the technical field of communication. The method includes: the gateway node receives the first message sent by the terminal device, and sends a second message to the control plane node, both the first message and the second message carry the temporary identity of the terminal device; the gateway node receives the message sent by the control plane node The third message, the third message is sent by the control plane node when the permanent identity of the terminal device cannot be obtained; the gateway node sends the fourth message to the terminal device according to the third message; the gateway node receives the fifth message sent by the terminal device, and the The fifth message carries the permanent identity of the terminal device; the gateway node sends the permanent identity to the control plane node according to the fifth message. In this application, even if the control plane node does not obtain the context of the terminal device, the permanent identity can be obtained through the forwarding of the gateway node, so that the terminal device may successfully access the network.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for acquiring an identity of a terminal device. Background technique [0002] Currently, a terminal device may access the network through a third generation partnership project (3rd Generation Partnership Project, 3GPP) technology, or may access the network through a non-3GPP technology. Among them, when a terminal device accesses a 5G network, whether it is accessed through 3GPP technology or non-3GPP technology, the terminal device needs to access and mobility management function (Access and Mobility Management Function, AMF) node. [0003] In the existing technology, when a terminal device accesses the 5G network through a non-3GPP technology, and the terminal device is re-registering instead of registering for the first time, the terminal device can negotiate with a non-3GPP Interworking Function (N3IWF) node , to establish an Inter...
