Abstract:
1. A method of compensating traffic channel signal strength measurements for improved handover decisions in a cellular radio telecommunication network, said method comprising the steps of: collecting by a Base Station System (BSS), signal strength measurements taken by a plurality of active mobile stations operating within a given cell, said measurements including signal strength measurements of the mobile stations' active traffic channels, broadcast channels from neighboring cells, and a broadcast channel from the given cell; instructing the mobile stations to stop measuring the signal strength of the broadcast channel from the given cell when a predefined event occurs; analyzing by the BSS, the collected signal strength measurements from the active mobile stations to determine for the given cell, a unique compensation offset factor for each traffic channel, wherein the unique compensation offset factor for a given traffic channel is based on a mean value of all the signal strength differences between the given traffic channel and the broadcast channel of the given cell, as collected from a plurality of mobile stations served by the given traffic channel; and making future handover decisions for mobile stations served by the given traffic channel by utilizing the unique compensation offset factor for the given traffic channel to define a cell border between the given cell and a neighboring cell.
