Abstract
Intersystem connection handover is based on transmission quality of a first radio communication system to a base station as determined by a subscriber station. If the transmission quality is lower than a threshold value, a transmission quality determination routine to a base station of the second radio communication system is triggered. The determination routine is continued until a criterion separate from the threshold is fulfilled.
