METHOD, APPARATUS, AND SYSTEM FOR ACCESSING MOBILE NETWORK.

摘要

The present invention relates to a method, an apparatus, and a system for accessing a mobile network. The method for accessing a mobile network comprises: obtaining a user identity of a user equipment (UE) for accessing a wireless local area network (WLAN) (11); obtaining, according to the user identity of the UE for accessing the WLAN, a user identity of the UE for accessing a mobile network, the user identity of the UE for accessing the mobile network being associated with the user identity of the UE for accessing the WLAN, and used for the UE to access the mobile network (12); and sending the user identity of the UE for accessing the mobile network to a trusted wireless access gateway (TWAG), so as to instruct the TWAG to enable the UE to access the mobile network (13). Through the association between the WLAN identity and the mobile user identity, the user identity of the UE for accessing the mobile network can be authenticated, and the UE can access the mobile network.
