Problems solved by technology

[0003] The main technical problem to be solved by the present invention is to provide a service data offloading method and system, which solves the problem that when the existing service data offloading, according to the subscription information of the user terminal, all services of the user terminal can only be selected to be connected to the core network or connected to Problems accessing the Internet

Embodiment 1

[0047] In this embodiment, for the main process of distributing user business data, please refer to figure 1 shown, including:

[0048] Step 101: Authenticate the user terminal and access it to the core network;

[0049] Step 102: receiving the service data message sent by the user terminal;

[0050] Step 103: Obtain the destination address information contained in the service data message;

[0051] Step 104: According to the obtained destination address information, the service data packets are distributed.

[0052] Wherein, the authentication of the user terminal in the above step 101 means that the user terminal will first be authenticated in the 3GPP AAA (that is, the authentication, authorization and accounting server) before accessing the WLAN. During the authentication process, the 3GPP AAA and the AC (that is, access controller) will judge whether the user terminal is allowed to access the core network EPC according to the SSID, subscription information and equipmen...

Embodiment 2

[0074] It can be seen that in the AC, according to the destination IP address and port number of the user terminal, the present invention can determine whether to distribute the service data message to the core network or distribute it to the Internet. And when the APN corresponding to the destination IP address of the service data message is a non-default APN, the tunnel between the AC and the PGW corresponding to the non-default APN can also be dynamically or statically maintained. In order to better understand the present invention, the present invention will be further described below for different situations in conjunction with the accompanying drawings:

[0075] See Figure 5 As shown, the process of AC sending service data packets to the default PGW is as follows:

[0076] Step 501: the user terminal selects an SSID to access according to the wireless mechanism of the WLAN;

[0077] Step 502: Authenticate the user terminal, TWAN (Trusted WLAN Access Network) is used a...

Abstract

The invention discloses a service data shunting method and system. After the user terminal is authenticated and connected to the core network; when receiving the service data message sent by the user terminal, the purpose is obtained from the service data message. Address information; and then according to the obtained destination address information, the business data packet is distributed; instead of the current distribution processing based on the subscription information of the user terminal; at the same time, using the destination address information contained in the business data message, you can The services not used by the user terminal are selected to be connected to the core network or the Internet according to their access points, instead of only connecting all the services of the user terminal to the core network or the Internet as in the existing system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a service data distribution method and system. Background technique [0002] WLAN (Wireless Local Area Network, WLAN) technology enables more users to perform data services through WLAN. With the business development of users and the acceleration of WLAN construction by mobile operators, some services can access the core network of mobile operators 3GPP through WLAN, and access the self-operated services of 3GPP (3rd Generation Partnership Project, 3GPP) operators. The S2a / b / c interface is introduced in 3GPP 23.402 to support the intercommunication between EPC and non-3GPP. In the EPC architecture, the WLAN access network can be used as a trusted network to directly connect to the Packet Data Network Gateway (PGW) through the S2a interface. The S2a interface uses the GTP or PMIP protocol for information exchange. Before the user terminal accesses the WLAN, it will first be a...
