Description

A method and corresponding device for acquiring location information

technical field

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

Background technique

With the increasing maturity and popularization of WLAN (Wireless Local Area Networks, wireless local area network) access technology, and users' demand for high-speed wireless access, operators at home and abroad are vigorously developing WLAN services. The WLAN service plays an increasingly important role as a distribution means of 2G (second-generation mobile communication technology) and 3G (3rd-generation, third-generation mobile communication technology).

WLAN access is a supplementary access method for fixed networks. How to effectively grasp and manage users' WLAN access in real time has become the key to developing WLAN value-added services. At the same time, this will help operators optimize their networks.

Currently, BBF (Broadband Forum, an international standards organization Broadband Forum) and 3GPP (The3rd Generation Partnership Project, third generation partnership project) are working on the standardization of FMC (Fixed Mobile Convergence, fixed network and mobile network integration), involving The scenario includes authentication, address allocation and policy control of 3GPP UE (User Equipment, user equipment) accessing from BBF network through RG (Residential Gateway, residential gateway), as shown in FIG. 1 . During the authentication process, the 3GPP UE initiates access authentication to the RG as the 802.1X customer service terminal. At this time, the RG acts as the 802.1X authenticator and the RADIUS (Remote Authentication Dial In User Service, remote user dial-in user service, remote user dial-in authentication system) client to the BBF AAA (Authentication Authorization Accounting, authentication, authorization, accounting) The server initiates an authentication request. During 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, packet data network gateway) via a BNG (Broadband Network Gateway, broadband network gateway device). Among them, the S2a session is established between the BNG and the PDN-GW, and through GTP (GPRS Tunneling Protocol, GPRS (General Packet Radio Service, General Packet Radio Service) tunneling protocol) or Proxy Mobile Internet Protocol (Proxy Mobile IP, PMIP for short) Tunnel implementation.

In the prior art, each user BNG needs to establish an S2a session with the PDN-GW. In order to support this scenario on the live network, all BNG devices need to be upgraded, which has a great impact on the live network. To solve this problem, a fixed network access gateway is used, such as: TWAG (Trusted WLAN Access Gateway, trusted WLAN access gateway). The network structure after introducing TWAG is shown in Figure 1. After introducing the fixed network access gateway, there is no need for large-scale upgrade of BNG equipment, which can minimize the impact on the existing network.

In the prior art, the mobile network needs to obtain the location information of the access node to which the UE is attached through the S2a session as a reference for charging. Currently, fixed networks cannot provide this location information to mobile networks.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

The mobile network user equipment UE attaches from the fixed network. During the authentication process of the UE, the RG is the authentication point, and the RG sends the location information of the UE to the TWAG.

Specifically, the RG inserts the location information of the UE into the authentication request message and sends it to the TWAG. If the BNG is separated from the TWAG, the authentication request message will be sent to the TWAG after passing through the BNG. At this time, BNG acts as a RADIUS proxy, and TWAG also acts as a RADIUS proxy.

In addition, the TWAG sends the location information of the UE to the PDN-GW when establishing a tunnel with the 3GPP PDN-GW; the 3GPP network element uses this 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 serving as the UE in a fixed network and/or a service set identifier (Service Set Identifier, SSID) selected by the UE.

When the AP acts as the access node device of the UE, the identifier of the access node device of the UE is the MAC (Media Access Control, Media Access Control) address of the AP, the link identifier of the AP, and the user of the AP. any one or any combination of names. In addition, since the AP is connected to the mobile network through the RG, the RG can obtain the identity of the AP through static configuration or dynamic interaction messages.

When the above-mentioned RG acts as the access node device of the UE, the identifier of the access node device of the UE is any one or any of the MAC address of the RG, the link identifier of the RG, and the user name of the RG. combination.

Method Two:

The mobile network user equipment UE attaches from the fixed network. During the authentication process of the UE, the RG is the 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 it to the BBF AAA.

If BNG and TWAG are integrated, in the process of UE requesting an address, TWAG inquires user information from BBF AAA after receiving the user's address request, and BBF AAA returns the location information of the UE to TWAG. If the BNG and TWAG are separated, the BNG will query the BBF AAA for the UE's location information after receiving the address request message, and the BBF AAA will return the UE's location information to the BNG; after that, the BNG will obtain the above UE's location information from the BBF AAA The location information is sent to TWAG.

In addition, when the TWAG establishes a tunnel with the 3GPP PDN-GW, it sends the location information of the above-mentioned UE to the PDN-GW; the 3GPP network element uses this 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 serving as the UE in a fixed network and/or an SSID selected by the UE.

When the access node device of the UE is acted by an 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 user name of the AP . In addition, since the AP is connected to the mobile network through the RG, the RG can obtain the identity of the AP through static configuration or dynamic interaction messages.

When the above-mentioned RG acts as the access node device of the UE, the identifier of the access node device of the UE is any one or any of the MAC address of the RG, the link identifier of the RG, and the user name of the RG. combination.
