<p>The invention relates to a cellular radio system and a method for improving the reliability of a handover in a cellular radio system, which comprises in each cell at least one base station (100) communicating with terminal equipments (102) located within its coverage area, which base stations calculate the location of each terminal equipment in the coverage area of the base station on the basis of the direction angle and distance of the terminal equipment, and which terminal equipments measure the signal strength from the base stations that are in the list of nearby base stations maintained by the terminal equipment, in order to determine the need for a handover. In order to enable fast measurements and reliable handover, the list of nearby base stations maintained by each terminal equipment (102) is updated on the basis of the location calculated for each terminal equipment.</p> |
