A METHOD FOR THE USER EQUIPMENT ACCESSING THE TELECOMMUNICATION SYSTEM AND THE TELECOMMUNICATION SYSTEM

摘要

A method for the user equipment accessing the telecommunication system and the telecommunication system include that the network side sets up the default bearer for the UE which accesses via the non-3GPP access network during the network side registration. The access user via the non-3GPP access network can be enabled to possess the function of "online forever". For different scenario, the default bearer can be setup for the UE accessed via the non-3GPP access network by the SAE anchor of the home network and/or the visit network. If the non-3GPP access network for accessing the UE is unreliable, setup the secure tunnel between the gateway of the non-3GPP access network and the ASE anchor to ensure the information safety. It's required to allocate the service address for the UE during the registration and then IMS registration can be launched after the registration.
