Description

Position information acquisition method and corresponding device
Technical Field
the present invention relates to the field of communications, and in particular, to a method and a corresponding apparatus for acquiring location information.
background
with the increasing maturity and popularization of WLAN (Wireless Local Area Networks) access technology and the demand of users for high-speed Wireless access, home and foreign operators are actively developing WLAN services. The WLAN service plays an increasingly important role as a offloading means for 2G (second generation mobile phone communication technology) and 3G (3rd-generation mobile communication technology).
the WLAN access belongs to a supplementary access mode of a fixed network, and how to effectively master and manage the condition of the user accessing through the WLAN in real time becomes a key for developing WLAN value-added services. At the same time, this will help the operator for network optimization.
currently, BBF (Broadband Forum, international standards organization Broadband Forum) and 3GPP (The3rd Generation Partnership Project, third Generation Partnership Project) are performing standardization work of FMC (Fixed Mobile Convergence) in a scenario involving authentication, address allocation, and policy control of 3GPP UE (User Equipment) accessing from a BBF network through RG (Residential Gateway), as shown in fig. 1. In the Authentication process, 3GPP UE initiates access Authentication to RG as 802.1X customer Service, and at this time, RG serves as 802.1X authenticator and RADIUS (Remote Authentication Dial In User Service) client to initiate Authentication request to BBF AAA (Authentication Authorization Accounting, Authentication, Authorization, Accounting) server. In the address request process, an 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). The S2a session is established between the BNG and the PDN-GW, and is implemented through a GTP (GPRS Tunneling Protocol, GPRS (General Packet Radio Service) Tunneling Protocol) or Proxy Mobile internet Protocol (Proxy Mobile IP, PMIP for short) tunnel.
In the prior art, each subscriber BNG needs to establish an S2a session with the PDN-GW. In order to support the scenario in the existing network, all BNG devices need to be upgraded, and thus the impact on the existing network is large. In order to solve the problem, a fixed network access gateway is introduced, such as: TWAG (Trusted WLAN Access Gateway). The network structure after TWAG introduction is shown in fig. 1. After the fixed network access gateway is introduced, large-scale upgrading of BNG equipment is not needed, and the influence on the existing network can be reduced as much as possible.
in the prior art, the mobile network needs to acquire the location information of the access node to which the UE is attached through the S2a session as a reference for charging. At present, the fixed network cannot provide the location information to the mobile network.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
the method comprises the following steps:
as shown in fig. 2, the method for acquiring location information includes:
The 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 position information of the UE to the TWAG.
Specifically, the RG inserts the location information of the UE into an authentication request message and transmits the same to the TWAG. If the BNG is separated from the TWAG, the authentication request message is sent to the TWAG after passing through the BNG. At this time, BNG acts as RADIUS Proxy, and TWAG also acts as RADIUS Proxy.
in addition, when the TWAG establishes a tunnel with the 3GPP PDN-GW, the TWAG sends the position information of the UE to the PDN-GW; the 3GPP network element uses the parameter as one of the bases for charging the UE.
in a specific implementation, the location information of the UE includes: an identity of an access node device in the fixed network as the UE and/or a Service Set Identifier (SSID) selected by the UE.
when the Access node device as the UE is regarded by the AP, the identifier of the Access node device of the UE is any one or any combination of a Media Access Control (MAC) address of the AP, a link identifier of the AP, and a user name of the AP. In addition, since the AP is connected to the mobile network through the RG, the RG can acquire the identity of the AP through static configuration or dynamic interactive messaging.
when the access node device serving as the UE is operated by the RG, the identifier of the access node device of the UE is any one or any combination of the MAC address of the RG, the link identifier of the RG, and the user name of the RG.
the second method comprises the following steps:
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 position information of the UE to the BBF AAA.
specifically, the RG inserts the location information of the UE into an authentication request message and sends it to the BBF AAA.
if the BNG and the TWAG are integrated, in the process of requesting the address by the UE, the TWAG queries the user information from the BBF AAA after receiving the address request of the user, and the BBF AAA returns the position information of the UE to the TWAG. If the BNG is separated from the TWAG, the BNG inquires the position information of the UE to the BBF AAA after receiving the address request message, and the BBF AAA returns the position information of the UE to the BNG; thereafter, the BNG transmits the location information of the UE acquired from the BBF AAA to the TWAG.
In addition, when the TWAG establishes a tunnel with the 3GPP PDN-GW, the TWAG sends the position information of the UE to the PDN-GW; the 3GPP network element uses the parameter as one of the bases for charging the UE.
in a specific implementation, the location information of the UE includes: an identity of an access node device in the fixed network as the UE and/or an SSID selected by the UE.
when the access node device as the UE is regarded 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 user name of the AP. In addition, since the AP is connected to the mobile network through the RG, the RG can acquire the identity of the AP through static configuration or dynamic interactive messaging.
When the access node device serving as the UE is operated by the RG, the identifier of the access node device of the UE is any one or any combination of the MAC address of the RG, the link identifier of the RG, and the user name of the RG.
the present invention will be described in detail below with reference to the drawings and examples.
