The invention relates to a handover method in a mobile communication system where the serving base station measures the level and/or quality of the uplink signal of a mobile station. The base station controller commands neighboring base stations to measure the level and/or quality of the uplink signal of the mobile station, when the serving base station has measured an uplink signal level and/or quality level lower than a predetermined triggering value. The base station controller performs a handover to the neighboring base station that has measured the most suitable uplink signal level and/or quality, when the serving base station has measured an uplink signal level and/or quality below a predetermined threshold value for handover. |
