Abstract:
A system for determining handover in a mobile communications network, the system comprising;means (7) for establishing communication between a mobile station (1) and a base (2) station over a communications channel, means (6) for determining whether the communications channel is a frequency hopping channel or a non-frequency hopping channel, means (6) for monitoring a first quality parameter of a signal received over the communications channel, means (6) for monitoring a second quality parameter of a signal received over the communications channel, a first (8) comparator for comparing the first quality parameter with a first threshold, thereby generating a first trigger signal when the first threshold is exceeded, a second comparator (9) for comparing the second quality parameter with a second threshold, thereby generating a second trigger signal when the second threshold is exceeded, and selector means (10), operably coupled to the determining means (6) for selecting the first trigger signal when said channel is a non-frequency hopping channel, and the second trigger signal when said channel is a frequency hopping channel, thereby to trigger a handover.
