摘要：
A method for determining the position of a mobile station within a cellular telephone system having a plurality of cells. Voice information signals are transmitted between a first base station transmitter and a mobile station on a transmission channel. Thereafter, transmissions from the first base station transmitter of voice information signals on the transmission channel are ceased for a predetermined period of time. During the predetermined period of time when transmissions of voice information signals from the first base station transmitter have ceased on the transmission channel, the mobile station makes positional measurements. The position of the mobile station is determined in accordance with the positional measurements.
