Method and apparatus for supporting location services via a home node B (HNB)
First Claim
1. A method of supporting location services, comprising:
- receiving a request for a location service for a user equipment (UE) by a home Node B (HNB);
exchanging Positioning Calculation Application Part (PCAP) messages with a location server via an HNB Gateway (HNB GW) to support the location service for the UE,wherein the PCAP messages are transferred in messages of a first protocol between the HNB and the HNB GW and are transferred in messages of a second protocol between the HNB GW and the location server; and
supporting the location service for the UE by exchanging Radio Resource Control (RRC) messages with the UE; and
wherein the exchanging PCAP messages comprises receiving a PCAP message from the location server, andwherein the exchanging RRC messages comprises sending an RRC message to the UE, the RRC message including a positioning request, or assistance data, or both obtained from the PCAP message.

Abstract
Techniques for supporting location services for a home Node B (HNB) and its user equipments (UEs) are disclosed. In an aspect, location services may be supported for a UE by having an HNB inter-work between user plane and control plane location solutions. In one design, the HNB receives a request for a location service for the UE and communicates (i) with a location server via the user plane location solution and (ii) with the UE via the control plane location solution to support the location service for the UE. The HNB inter-works between the user plane and control plane location solutions. In another aspect, a location server may be used to support assisted GNSS (A-GNSS) for HNBs and UEs. In one design, an HNB exchanges PCAP messages with the location server via an HNB GW and exchanges RRC messages with a UE to support a location service for the UE.
