Title:
SECURITY PROTECTION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/148469
Kind Code:
A1
Abstract:
A security protection method, apparatus and system. The method comprises: a target AMF receiving, from an initial AMF, a first request of a terminal, a security context of the terminal and a subscription permanent identifier of the terminal (S210); and the target AMF responding to the first request (S220). Since an initial AMF acquires a security context of a terminal and a subscription permanent identifier of the terminal by means of an authentication process, a target AMF can trust the above-mentioned information from the initial AMF; and the target AMF can directly respond to a first request by using the information received from the initial AMF and does not need to initiate the authentication process to acquire the security context or the subscription permanent identifier, and similarly, also does not need to send a request for acquiring a context, thereby effectively reducing a signaling process after the target AMF receives the first request, and effectively shortening a time delay required for establishing or updating a connection between the terminal and the target AMF.
