Patent ID: 7215969

Claim:
A method for collecting data to identify an RF dead zone in a cell of a wireless network using a mobile station, the method including the steps: a) at a base station associated with a cell, receiving position data from a powered up mobile station located within the cell, the position data sent by the mobile station when the mobile station determines that a received pilot strength measurement message is less than a predetermined threshold, wherein the position data includes multiple coordinates indicating a location of the mobile station within the cell; b) communicating the position data from the base station to a mobile switching center associated with the base station and the wireless network; and c) storing the position data in an RF dead zone network associated with the wireless network; before step a), further including: d) at the powered-up mobile station, receiving information from at least three RF transmitting devices; e) at the powered-up mobile station, determining the multiple coordinates forming the position data from the received information; and f) at the powered-up mobile station, transmitting the position data to the base station.
