    Abstract: A cellular system transfers a call from a source base-site (200) to one target base-site (205, 210). A source base-site (200) measures the signal strength (RSSIS) of a mobile (225), provides a forecasted signal strength (RSSIF) and sets up two time windows. The source base-site (200) sends the measured and forecasted signal strengths to candidate base-sites (205, 210) found by the mobile (225) which measure the mobile (225) signal strength (RSSIT) and compare it to (RSSIS + hysteresis value). If RSSIT> RSSIS, the call is transferred to the best responding cell. If RSSIT RSSIF at any candidate base-sites (205, 210), the call is transferred to the responding base-site (205, 210). If the source base-site (200) receives no responses during the second time window, the process ends.
