Description

Method for acquiring location information and corresponding device

Technical field

The present invention relates to the field of communications, and in particular, to a method for acquiring location information and a corresponding device.

Background technique

With the maturity and popularity of WLAN (Wireless Local Area Networks) access technologies and the demand for high-speed wireless access by users, domestic and foreign operators are making great efforts to develop WLAN services. As a means of diversion of 2G (second-generation mobile communication technology) and 3G (3rd-generation, third-generation mobile communication technology), WLAN services are becoming more and more important.

WLAN access is a supplementary access method for fixed networks. How to effectively control and manage users accessing WLANs in real time has become the key to developing WLAN value-added services. At the same time, this will help operators to optimize their networks. Currently, BBF (Broadband Forum, International Standards Organization Broadband Forum) and 3GPP (The 3rd Generation Partnership Project) are undergoing standardization work for FMC (Fixed Mobile Convergence). The scenario includes authentication, address allocation, and policy control of the 3GPP UE (User Equipment) accessing from the BBF network through the RG (Residential Gateway), as shown in FIG. 1 . During the authentication process, the 3GPP UE initiates access authentication to the RG as the 802.IX client. At this time, the RG acts as the 802.IX authentication device and the RADIUS (Remote Authentication Dial In User Service) client to the BBF AAA. (Authentication Authorization Accounting, Authentication, Authorization, Accounting) The server initiates an authentication request. In the address request process, the address request message initiated by the 3GPP UE requests an IP address from a PDN-GW (Packet Data Network Gateway) via a BNG (Broadband Network Gateway Device). The S2a session is established between the BNG and the PDN-GW, and the GTP (GPRS Tunneling Protocol, GPRS (General Packet Radio Service) tunneling protocol) or the Proxy Mobile IP (PMIP) is used. Tunnel implementation. In the related art, each user BNG needs to establish an S2a session with the PDN-GW. To support the scenario on the live network, all BNG devices need to be upgraded, so the impact on the live network is large. To solve this problem, a fixed network access gateway is referenced, such as: TWAG (Trusted WLAN Access Gateway). The network structure after the introduction of TWAG is shown in Figure 1. After the introduction of the fixed network access gateway, large-scale upgrade of the BNG equipment is not required, and the impact on the existing network can be minimized.

In the related art, the mobile network needs to obtain the location information of the access node attached to the UE through the S2a session, as a reference for charging. Currently, fixed networks are not able to provide this location information to mobile networks.

If the BNG is separated from the TWAG, the authentication request message is sent to the TWAG after passing through the BNG. At this point, the BNG acts as a RADIUS proxy and TWAG also acts as a RADIUS proxy. In addition, when establishing a tunnel with the 3GPP PDN-GW, the TWAG sends the location information of the UE to the PDN-GW; the 3GPP network element uses the parameter as one of the basis for charging the UE.

Method Two:

The mobile network user equipment UE is attached from the fixed network. In the authentication process of the UE, the RG is an authentication point, and the RG sends the location information of the UE to the BBF AAA.

Specifically, the RG inserts the location information of the UE into the authentication request message and sends the location information to the BBF AAA.

If the BNG and the TWAG are unified, in the process of requesting the address by the UE, the TWAG queries the BBF AAA for the user information after receiving the address request of the user, and the BBF AAA returns the location information of the UE to the TWAG. If the BNG is separated from the TWAG, the BNG queries the BBF AAA for the location information of the UE after receiving the address request message, and the BBF AAA returns the location information of the UE to the BNG; thereafter, the BNG acquires the UE of the UE from the BBF AAA. Location information is sent to TWAG.

In addition, when establishing a tunnel with the 3GPP PDN-GW, the TWAG sends the location information of the UE to the PDN-GW; the 3GPP network element uses the parameter as one of the basis for charging the UE.

In a specific implementation, the location information of the UE includes: an identifier of an access node device that is the UE in a fixed network, and/or an SSID selected by the UE. When the access node device that is the UE is used by the AP, the identifier of the access node device of the UE is any one or any combination of the MAC address of the AP, the link identifier of the AP, and the username of the AP. .
