Terminal equipment registration method and device

Abstract

The invention provides a terminal equipment registration method and device. In the method, the time for sending a registration acceptance message by the network is earlier than the time for sending the registration acceptance message in the registration process in the prior art; in other words, the registration acceptance message is sent as long as the first-level authentication of the terminal equipment is completed and a security context is established; however, in the prior art, the registration acceptance message is sent only after all the slices complete the second-level authentication, so that not only can the problem caused by nested authentication be solved, but also the access flexibility of the terminal equipment is greatly improved, and the setting or management of a timer during registration becomes simpler and more convenient. At the moment, the terminal equipment can decide when it is convenient to perform second-level authentication on the terminal equipment according tothe second-level authentication information fed back by the network. For example, the terminal equipment can access the slice, establish a session and send and receive data service according to the successfully authenticated slice, and makes a request to access other slices when it is idle at a later time.

Description

Technical field [0001] This application relates to the field of mobile communication technology, and in particular to a method and device for registering terminal equipment. Background technique [0002] Before the terminal device accesses the network or the slice, it needs to perform two-way authentication with the slice and obtain authorization from the network. Currently, two levels of authentication may be required between terminal equipment and the network. Among them, the authentication between the terminal equipment and the operator's network is called the first-level certification, and the authentication between the terminal equipment and the third-party network outside the operator's network is called the second-level certification. [0003] Currently, one possible authentication method is: terminal device initiates a registration request -> Level 1 certification of carrier network -> Secondary certification of third-party networks -> Network authorization of the...
