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

Abstract

Disclosed is a method for setting up multiple connections, including: after a BNG has received a PPP or PPPoE access request message initiated by a UE, forwarding same to a TWAG via an L2TP tunnel; and when the TWAG determines that the setup of a PDN connection for the UE is allowed according to the acquired information about an APN which the UE wants to access and the access list information about the APN, setting up the PDN connection with a PDN gateway for the UE according to the information about the APN which the UE wants to access, and sending to the UE the IP address information allocated to the UE by the PDN gateway via the BNG. Between the BNG and the TWAG, different sessions are set up on one and the same L2TP parameter connection for different UEs carrying information about the same APN; or between the BNG and the TWAG, different sessions are set up on one and the same L2TP tunnel for different UEs carrying information about different APNs. Disclosed at the same time is a system for setting up multiple connections. The present invention realizes the setup of multiple connections based on the information about an APN, and expands the application of the FMC 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 GSMEvolution, enhanced data rate GSM (Global System for Mobile communication, Global System for Mobile...
