Abstract
To reduce the effect of non-uniform radiation patterns on handover decisions in a cellular radio network using adaptive antennas, a mobile station monitors the beacon signal of its serving base station 302a in addition to those of neighbouring cells 302. The beacon signal defines the cell footprint whereas the traffic channels use an adaptive antenna with a coverage which may at times differ considerably from this. In the GSM network disclosed the traffic channel level and quality are monitored 301 and also a comparison is made between the serving base station beacon signal and those of neighbouring cells to determine the need for handover. In a power budget test 308 this comparison allows an alternative link to be chosen at lower power levels to conserve the mobile station batteries and reduce interference. The comparison is made relative to a fixed pattern so that cell boundaries are maintained and interference is controlled.
