First Claim
Patent Images
1. A method for locating an unlicensed mobile access (UMA) subscriber, comprising:
- establishing, using a mobile station (MS) supporting both UMA and licensed wireless network sessions, a first UMA session with a UMA service provider;
identifying an access point (AP) used to provide an unlicensed wireless link to host the first UMA session;
determining if location information is available for the AP;
when the location information is not available, employing a licensed wireless network-based location service to identify the location of the MS; and
storing location information for the MS obtained via the licensed wireless network-based location service as a location for the AP, said location information made accessible to the UMA service provider.

Abstract
A method and system for locating an unlicensed mobile access (UMA) subscriber. The method enables a user of a mobile station comprising a hand-set or the like that supports voice and data access via both licensed and unlicensed radio spectrums to be located. Accordingly, services requiring location information, such as 911 services, may be accessed when operating the mobile station under both UMA and licensed wireless network (e.g., cellular) sessions.

6. A method for locating an unlicensed mobile access (UMA) subscriber, comprising:
-
establishing, using a mobile station (MS) supporting both UMA and licensed wireless network sessions, a first UMA session with a UMA service provider; identifying an access point (AP) used to provide an unlicensed wireless link to host the first UMA session; determining if location information is available for the AP; and when the location information is not available, employing a licensed wireless network-based location service to identify the location of the MS, wherein location of the MS is determined by employing at least one of Assisted GPS (AGPS), Angle of Arrival (AOA), Enhanced Observed Time Difference (E−
OD), Cell Identity plus Timing Advance (Cell ID+TA), and Time Difference of Arrival (TDOA) location techniques.

7. A system comprising:
-
an unlicensed mobile access (UMA) network controller (UNC) operable to communicate with a telecommunications network and communicably coupled to one or more unlicensed wireless base stations comprising wireless access points (AP) that support communication with one or more mobile stations (MS) via unlicensed wireless links, each MS configured to support both UMA sessions and licensed wireless network sessions; and a service provisioning server, communicably coupled to the UNC, to store data corresponding to UMA subscriber services provided by an operator of the UNC, wherein the UNC is operable to perform operations to support the UMA subscriber services, including; establishing a first UMA session for a MS; identifying an AP used to provide an unlicensed wireless link used to host the first UMA session; determining if location information is available for the AP via the service provisioning server; when the location information is not available, submitting a location service request to a licensed wireless network-based location service to identify the location of the MS; and storing location information returned by the licensed wireless network-based location service identifying the location of the MS as the location of the AP. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
