Title:
A METHOD, DEVICE AND SYSTEM OF NEGOTIATING THE ENCRYPTING ALGORITHM BETWEEN THE USER EQUIPMENT AND THE NETWORK
Document Type and Number:
WIPO Patent Application WO/2007/124671
Kind Code:
A1
Abstract:
A method of negotiating the encrypting algorithm between the user equipment and the network, and its device and system are disclosed. When registering, the UE negotiates the encrypting algorithm of the singling plane with the network. And the encrypting algorithm of the data plane is negotiated between the UE and the network when the traffic is established. The negotiating of the data plane and the singling plane can be divided, so the encrypting between the UE and the core network can be processed accurately after the MME and the UPE divided.
