Title:
SECURITY ACTIVATION STATUS DETERMINATION METHOD AND RELATED PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/249083
Kind Code:
A1
Abstract:
Disclosed by the embodiments of the present application are a method and device for determining a security activation state, said method comprising: a first access network device receiving a redundancy indication; the first access network device establishing a first session and a reference session with a user equipment according to the redundancy instruction, the first session and the reference session being redundant sessions; the first access network device sending to a second access network device a session offload message of the reference session, the session offload message being used for instructing the second access network device to establish a second session with the user equipment according to the session information; the first access network device sending a target message to the second access network device, and, if the target message carries a first identifier, the target message being used for instructing the second access network device to assign a second identifier to the first identifier, the first identifier being used for indicating the security activation state of the first session and the second identifier being used for indicating the security activation state of the second session. Therefore, by means of the described solution, it is possible to ensure that the safe activation states of the redundant transmission paths are the same.
