Description

The present invention claims the priority of the Chinese patent application filed on December 1, 2008, the Chinese Patent Application No. 200810217768. The entire contents are incorporated herein by reference. TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for positioning a home base station. Background of the Invention Femtocell technology is a solution for extending indoor coverage of mobile communications. The Femtocell is usually installed in a small environment, and the user can access the core network through Femtocell using various mobile terminal devices, such as a mobile phone, a personal computer or a palmtop computer. Femtocell is also known as a home base station or an indoor base station.

The Femtocell in the WIMAX network is a low power WIMAX base station (BS). This BS provides a small range of wireless coverage, mainly in indoor homes and SOHO environments. It is accessed using a wired broadband network (such as a DSL/IP network), where the wired broadband network may be a different carrier than the WIMAX network.

The WIMAX Femtocell provides access to WIMAX mobile terminals on an authorized spectrum, which itself accesses the WIMAX core network via a wired broadband network. Like other WIMAX access layer devices, WIMAX Femtocell is managed by WIMAX NAP.

For the WIMAX Femtocell network structure, refer to Figure 1. The MS and Femtocell are connected through the air interface R1 interface. In the WIMAX network of profile A/C, FAP (Femtocell Access Point) assumes the role of BS. In profileB's WIMAX network, FAP assumes the role of ASN. FAGW (Femtocell Access Gateway) is used as an access gateway for FAP access to the WIMAX network through a wired network to complete the conversion of signals and data packets. In the profile A/C WIMAX network, the FAP is connected to the ASN-GW of the WIMAX network through the FAGW. In profileB's WIMAX network, the FAP is connected to the ASN of the WIMAX network through the FAGW. The connection to the CSN is completed through the specified access ASN.

The FAGW establishes a connection with the FAP AAA server through the contract relationship. On the FAP AAA server, the information about the subscription information of the Femtocell is saved, and the access authentication and other management and maintenance of the Femtocell are completed. The FAP must first authenticate and authorize the FAP AAA server in the WIMAX network to allocate radio resources by the NAP and provide R1 air interface services for the MS. The current Femtocell positioning technology, when the Femtocell device enters the network through the wired network, the wireless network determines the location of the Femtocell in the wired network according to the information of the access point IP address of the wired network or the registered house address of the user, and then according to the wired network and the wireless The setting of the network determines the location of the Femtocell in the wireless macro network. Further, the wireless network determines the air interface attribute setting of the Femtocell according to the location in the macro network. Although the positioning method is simple, since the wired topology and the wimax macro network topology are not identical, the obtained macro network location information is inaccurate, and the exact location of the Femtocell in the macro network cannot be determined, further resulting in calculation based on the location. Femtocell air interface parameters are not guaranteed to work optimally with wireless macro networks and other Femtocells. Summary of the invention
