Embodiment 1

[0061] figure 2 A flow chart of the method for establishing multiple connections in Embodiment 1 of the present invention, such as figure 2 As shown, the method for establishing multiple connections in this example includes the following steps:

[0062] In step 201, the UE initiates a PPPoE access request; the UE and the BNG complete PPPoE negotiation and obtain a PPPoE session ID (PPPoE Session ID).

[0063] In step 202, the PPP Link Control Protocol (LCP, Link Control Protocol) negotiation is completed between the UE and the BNG.

[0064] Step 203, the UE carries the APN information and interacts with the BNG, BBF AAA server, and 3GPP AAA server to complete UE identity local authentication, and the 3GPP AAA server sends Layer 2 Tunneling Protocol (L2TP, Layer 2 Tunneling Protocol) parameter information to the BNG.

[0065] In step 204, an L2TP tunnel is established between the BNG and the TWAG.

[0066] If an L2TP tunnel or a tunnel with the same APN information already...

Abstract

The invention discloses a multi-connection establishing method. The method comprises the following steps: BNG (broadband network gateway) transmits a PPP (point-to-point protocol) or PPPoE (point-to-point protocol over Ethernet) access request message to TWAG (trusted WLAN access gateway) through a L2TP (layer 2 tunneling protocol) tunnel after receiving the PPP or PPPoE access request message from UE (user equipment); the TWAG establishes PDN (packet data network) connection of the UE with the PDN gateway according to APN (access point name) information to be accessed by the UE and sends IP address information allocated by the PDN gateway for the UE to the UE through the BNG when determining that the PDN connection of the UE is allowed to be established according to the APN information to be accessed by the UE as well as APN access list information, wherein the BNG and the TWAG establish different sessions for different UEs carrying identical APN information on the same L2TP parameter connection or establish different sessions for different UEs carrying different APN information on the same L2TP tunnel. The invention also discloses a multi-connection establishing system. The method and the system provided by the invention realize multi-connection construction based on APN information, and expand the application of FMC (fixed mobile convergence) architecture.

Description

technical field [0001] The present invention relates to the technology of establishing multiple connections, in particular to a method and system for establishing multiple connections. Background technique [0002] With the development of network technology and the continuous strengthening of users' business needs, terminals are gradually developing towards multi-mode. Multi-mode terminals can choose to access different types of access networks to carry diverse services. Since different network connections have different characteristics and transmission capabilities, the needs of users for multi-service diversity can be better met. Multi-mode terminals can realize seamless connection between different types of wireless access networks, such as cellular universal mobile telecommunications system (UMTS, Universal Mobile Telecommunication System) / EDGE (Enhanced Data Rate for GSM Evolution, enhanced data rate GSM (G1obal System for Mobile communication, Global System for Mobil...
