Abstract
A system and method for improving the accuracy of a location estimation measurement within a telecommunication system is disclosed. During a cessation of transmissions by a local base transceiver system in communication with the mobile station, the mobile station communicates with other, more remote base transceiver systems and trilateration and other distance measuring techniques are employed to calculate the position of the mobile station in relation to those remote base transceiver systems. In another embodiment of the present invention, the local base transceiver system is also used to calculate the position. In still another embodiment, during a cessation of transmissions by the mobile stations in communication with a local base transceiver system, the local base transceiver system is better able to use remote mobile stations for trilateration.
