Title:
REGISTRATION METHOD AND APPARATUS FOR TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/177523
Kind Code:
A1
Abstract:
Provided are a registration method and apparatus for a terminal device. In the method, the time when a network sends a registration acceptance message is earlier than the time when a registration acceptance message is sent in a registration process in the prior art, i.e. in the present application, the registration acceptance message is sent once first-level authentication on a terminal device has been completed and a security context has been established, whereas in the prior art, the registration acceptance message is sent only after second-level authentication on all slices has been completed. In this way, not only can the problem caused by nested authentication be solved, access flexibility of a terminal device can also be greatly increased, so that the setting or management of a timer during registration becomes simpler. At this moment, the terminal device can determine, according to second-level authentication information fed back by the network, the time for which performing second-level authentication is more convenient for the terminal device. For example, according to a slice that has been authenticated successfully, the terminal device can access the slice, establish a session, and send and receive a data service. In addition, the terminal device then requests access to other slices when later being idle.
