Method and arrangements for an event triggered DRX cycle adjustment

摘要

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.

1. A method in a user equipment located in a serving cell of a mobile communications network, said method comprising:
monitoring downlink communication at predetermined time intervals when operating in discontinuous reception mode, performing communication measurements regarding at least one of the serving cell and one or more neighbor cells, and after the occurrence of a first event, sending at least one of measurement data and a first event report from said user equipment to said network, wherein said sending is triggered by the occurrence of the first event, wherein said monitoring is caused to be performed at shortened time intervals after the occurrence of a second event, wherein said second event is defined to indicate a higher probability of receiving a handover command than said first event, and wherein said first event and said second event are defined in relation to a same measurement parameter, and wherein said first event is caused by a first measurement on said same measurement parameter, and said second event is caused by a second measurement based on said same measurement parameter.
