Method and system for providing location information for emergency services
First Claim
1. A system that facilitates determination of a location of a mobile station, comprising:
- a cellular communications network that is sparsed to include at least one sparse transceiver station from which the mobile station communicates radio signals;
a synchronization component that facilitates synchronization of the at least one sparse transceiver station with a non-sparse transceiver station; and
a timing component that determines timing information of the non-sparse transceiver station and facilitates calculation of the location of the mobile station based on the timing information.

Abstract
Emergency Services architecture for determining the location of a wireless caller. The architecture leverages a synchronization feature of GSM networks of the Base Station Subsystem (BSS) to enable employment of sparse networks by removing WLS (Wireless Location Sensor) equipment from selected cell sites. Thus, the location of a wireless caller within a sparse site can be determined. Sparse network location services can be provided further utilizing Time Difference of Arrival (TDOA) technology, and other network-based location technologies such as Enhanced Observed Time Difference (EOTD) and Angle of Arrival (AOA). Hybrid network-based/handset-based location technologies may also be used with the disclosed invention.

16. A system that facilitates determination of a location of a mobile station, comprising:
-
a sparse site from which the mobile station transmits radio signal information; and a synchronization component that facilitates synchronization of the sparse site with a geolocation system, which geolocation system processes the radio signal information and determines the location of the mobile station using timing information from a non-sparse site. - View Dependent Claims (17, 18, 19, 20, 21, 22)
