DETERMINING LOCATIONS OF MOBILE STATIONS IN WIRELESS NETWORKS
First Claim
1. A method, comprising:
- obtaining by a mobile station (MS), from a navigation service remotely disposed from the MS a decryption key to decrypt encrypted location information;
obtaining by the MS, from a base station (BS) remotely disposed from the MS, encrypted location information of the BS, the BS and the navigation service being separate and distinct from each other;
decrypting the encrypted location information of the BS using the obtained decryption key to recover the location information of the BS; and
determining a location of the MS based, at least in part, on the decrypted location information of the BS.

Abstract
Wireless network methods and apparatuses that may determine and provide, in real-time, the geographical locations of mobile stations of the wireless network are described herein. In one implementation, in order to determine the location of a mobile station (MS), the MS may obtain from a navigation service a decryption key to decrypt encrypted location information of multiple base station'"'"'s (BS'"'"'s) in its local area. The encrypted location information of the BS may then be decrypted and based at least in part on the recovered location information of the BS, determine the location of the MS. In another implementation, in order to determine and provide the location of an MS of a wireless network, a combination of location agents, location controller, and a location server may be employed to determine and provide the current location of the MS to requesting authorized clients.

7. An apparatus, comprising:
-
one or more processors; storage medium coupled to the processors, having stored therein programming instructions to be operated by the one or more processors to; receive, from a location controller (LC) remotely disposed from the apparatus, a request for current location measurements of a mobile station (MS) of a wireless network, remotely disposed from both the LC and apparatus, the LC being associated with the MS; gather the requested current location measurements of the MS; and send to the LC, the requested current location measurements of the MS. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A system, comprising:
-
a wireline communication interface to communicate with a location server; one or more wireless communication interfaces to communicate with a plurality of location agents (LAs) remotely disposed from the system; one or more processors coupled to the communication interfaces; and a location control service operated by the one or more processors, the location control service adapted to; receive a request via the wireline communication interface from the location server for a current location of a mobile station (MS) of a wireless network, the MS being remotely disposed from the system and the LA; request one of the LAs, via the one or more wireless communication interfaces, to provide current location measurements of the MS, the requested LA being associated with the MS; receive from the requested LA, via the one or more wireless communication interface, the requested current location measurements of the MS; determine the current location of the MS based at least in part on the received current location measurements of the MS; and provide to the location server, via the wireline communication interface, the determined current location of the MS. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. An article of manufacture, comprising:
-
storage medium; programming instructions stored in the storage medium, the programming instructions adapted to enable an apparatus to provide a navigation service, including provision of current locations of mobile stations, the navigation service being remotely disposed from the mobile stations and configured to; receive a location inquiry from a client for a location of a mobile station (MS) of a wireless network, request a location controller (LC) that is remotely disposed from the apparatus and the MS the location of the MS substantially in real time based on location measurements of the MS obtained from one or more location agents associated with the MS, receive the determined location of the MS from the LC, and send the location of the MS to the client. - View Dependent Claims (22, 23, 24, 27)
