Positioning of a wireless device served by a femto cell
First Claim
1. A method of performing positioning, comprising:
- obtaining at least one identity assigned to a femto cell and used to differentiate the femto cell from sectors in a wireless network, wherein the at least one identity assigned to the femto cell is within a range of values reserved for femto cells, wherein each range of values being reserved for femto cells of a different type and a type of the femto cell is determined based on the value of the identity;
sending the at least one identity of the femto cell to a location server; and
performing positioning with the location server to obtain a location estimate for a mobile station, the location server differentiating the femto cell from the sectors in the wireless network based on the at least one identity.

Abstract
Techniques for supporting positioning are described. In an aspect, positioning of mobile stations served by femto cells may be supported by having the femto cells transmit at least one identity used to differentiate the femto cells from other cells/sectors in a wireless network. The at least one identity may also convey certain information for the femto cells, which may be pertinent for positioning of the mobile stations. In one design, a femto cell may send the at least one identity assigned to the femto cell and the location of the femto cell to mobile stations as an aid for positioning. A mobile station may receive and forward the least one identity and the location of the femto cell to a location server. The mobile station and the location server may then perform positioning based on the at least one identity and the location of the femto cell.
