Patent ID: 7974640

Claim:
A system for automatically determining cell transmitter parameters to facilitate the location of wireless devices, comprising: a location processing node; a first wireless device, wherein said first wireless device is configured to communicate with said location processing node via a communications link, and to make scanning measurements of signals from one or more geographically distributed transmitters, wherein said first wireless device is further configured to assist the location processing node in determining key transmitter information by receiving and measuring characteristics of said signals and providing information about said characteristics via the communications link to said location processing node; and a server configured to communicate with a second wireless device, and to cause said second wireless device to make signal measurements of signals from one or more transmitters and to provide measurement information to said location processing node; wherein said characteristics measured by said first wireless device are useful, in combination with characteristics measured by other wireless devices, to determine the key transmitter information; and wherein said key transmitter information includes cell identification information, cell transmitter location information, and cell transmitter signal timing information.
