Abstract:
A method for mobile station locating in connection with a potential hand-off, comprising the steps of:measuring by the mobile station of downlink received signal strength on a currently used traffic channel broadcast from a first base station of a currently serving cell;measuring by the mobile station of downlink received signal strength on a measurement channel broadcast from a second base station of a neighboring cell to the currently serving cell;wherein the first base station supports either a smart antenna or sector antenna for broadcasting the traffic channel and the second base station supports a sector antenna for broadcasting the measurement channel;adjusting the mobile station measured downlink received signal strengths on the serving cell's traffic channel and the neighboring cell's measurement channel in order to take into account any operational and physical differences which exist between the sector antenna used to broadcast the measurement channel and the antenna used to broadcast the traffic channel; andcomparing the adjusted downlink received signal strength measurements to each other to determine whether the mobile station is better served by the neighboring cell.
