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
exchanging Radio Resource Control (RRC) messages with the UE to support the location service for the UE.

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.

15. A method of supporting location services, comprising:
-
performing a location procedure with a location server by a first home Node B (HNB) to support a location service for a user equipment (UE) communicating with the first HNB; obtaining an indication to handover the UE from the first HNB to a second HNB; and transferring location status information from the first HNB to the second HNB, wherein the location procedure is continued by the second HNB and the location server based on the location status information provided by the first HNB. - View Dependent Claims (16, 17, 18, 19, 20)
