Method and system for mobile user to access fixed network

摘要

Disclosed is a method for a mobile user to access a fixed network, comprising: after a BNG and a TWAG establish a multi-protocol label switching (MPLS) tunnel and/or pseudowire, or a layer 2 tunneling protocol (L2TP) tunnel and/or session, the TWAG establishes a GPRS tunneling protocol (GTP)/proxy mobile internet protocol (PMIP) connection with a mobile network gateway according to user information, and acquires the address and service parameter of the user; and the TWAG transmits the service parameter of the user to the BNG via an MPLS control message or an L2TP control message. Also disclosed is a system for a mobile user to access a fixed network. The present invention standardizes user QoS security after the introduction of a TWAG, and can provide a user with better communication service, thus improving user experience.

1. A method for the access of a mobile UE through a fixed network, comprising:
after a Broadband Network Gateway (BNG) establishes a Multi-Protocol Label Switching (MPLS) tunnel and/or Pseudo Wire (PW) or a Layer 2 Tunnel Protocol (L2TP) tunnel and/or session with a Trusted WLAN Access Gateway (TWAG), establishing, by the TWAG, a GPRS Tunnelling Protocol (GTP)/Proxy Mobile Internet Protocol (PMIP) connection with a mobile network gateway according to UE information, and acquiring an address and service parameter of the UE; and sending, by the TWAG, the service parameter of the UE to the BNG through an MPLS control message or an L2TP control message.
