| 摘要 |
<p>The invention relates to a handover in a mobile communication system in which a mobile station measures (51) the level of the downlink signals (BTS_DOWNLINK) of the neighbouring cells of the serving cell, and transmits the measurement results to a fixed network which measures (52) the receive level (MS_UPLINK) of the mobile station uplink signal at the serving cell. At least some of the cells of the mobile communication system are assigned as chains of two or more cells. The fixed network reacts to a sudden drop (53) in the receive level of the mobile station uplink signal below a predetermined threshold level (LRD) at the serving cell by carrying out (55, 56) a handover to a chained cell on the basis of one or more of the latest signal level (BTS_DOWNLINK) measurements.</p> |
