Abstract
The invention relates to methods and arrangements for an event triggered DRX cycle adjustment. A user equipment located in a serving cell of a mobile communications network monitors downlink communication at predetermined time intervals when operating in discontinuous reception mode. The user equipment also performs communication parameter measurements regarding at least one of the serving cell and one or more neighbor cells. After the occurrence of a first event, the user equipment sends at least one of measurement data and a first event report to the network. The sending is triggered by the occurrence of the first event. The monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein the second event is defined to indicate a higher probability of receiving a handover command than the first event.
