ABSTRACT:
A Base Station System (BSS) and method for compensating traffic channel signal strength measurements to provide improved handover decisions. Each active mobile station in a given cell is instructed to measure and report signal strengths of the mobile station's active traffic channel, broadcast channels from neighboring cells, and a broadcast channel from the given cell over a predefined period of time. An offset value calculator analyzes the signal strength measurements of the active traffic channel and the given cell's broadcast channel, and calculates an updated value for a compensation offset factor. The updated value is then used within a handover algorithm to determine when to hand over mobile stations during future connections on the active traffic channel.
