<p>This invention relates to a new method of selecting the best radio access unit to roam to or make a handover to. The method is based on a database, keeping track on short live historical information on busy status and RSSI of radio access units, which guarantees the lowest chance on a blocked call, thereby preventing time-consuming call-set-up procedures as well as reducing the usage of (battery)power. The scanning of the environment is not deployed at an higher rate than usual, to obtain the best radio access unit selection, but instead the scanning rate is lowered, thereby saving power in the remote radio communication unit and hence extend the operational lifetime of the battery fed equipment. The selecting method can be used within a DECT multicell environment.</p> |
