Method of reducing dead zones within a UMTS system, corresponding mobile telecommunication system and mobile station

摘要

The present invention relates to a method and a system for reducing the dead zones within a third generation mobile telecommunication system (UMTS). When a mobile station (MS) communicating with a service base station (BS1) generates a dead zone on at least one uplink of a next base station (BS2), criteria are determined, according to the invention, based on parameters regarding the uplink and/or downlink between the mobile station (MS) and the base station (BS1) which, if they are not complied with for the uplink and/or downlink, trigger a radio link interruption in the mobile station (MS). When the power transmitted on the uplink becomes zero, the degradation in the radio coverage of the cell associated with the next base station (BS2) due to the mobile station (MS) disappears.
