The invention discloses a method and a system for accessing to a mobile core network through a trusted fixed network. The method and the system are used to solve a technical problem that user equipment (UE) can not access business provided by a mobile operator caused by the fact that the UE can not trigger the mobile core network to assign IP addresses for the UE. In the method, after interaction of existing messages between the mobile UE and the fixed network, a routing gateway (RG) sends messages to broadband network gateway/broadband remote access server (BNG/BRAS), to trigger the message interaction between the fixed network and the mobile core network and request the mobile core network to assign IP addresses for the UE. And then the RG obtains the IP addresses, and provides the IP addresses to the UE after corresponding processing of IP address mapping relationships. The UE using the IP addresses provided by the RG accesses the business through the mobile network or directly through the fixed network. The method and the system enhance the messages between the UE and network elements of the fixed network (including the RG and the BNG/BRAS), so that the UE can access the mobile core network through a trusted WLAN network and access the business provided by the mobile network.
