Abstract
A user equipment, UE, in a radio communication network is given a threshold time value that the UE uses to decide whether it should trigger a fast dormancy request to a network node or not. The determination of the threshold time value can be adapted so that it minimizes UE battery consumption when the load in the network node is low and at other times minimizes the load on the network node. That is, if the UE estimates that a predicted time interval until reception of a data burst is less than threshold time value it will not trigger a fast dormancy request, and if the estimated time interval is larger than the threshold time value it will trigger a fast dormancy request. Since the network typically controls state switching, there is a large benefit for the UE to comply with the scheme, otherwise the network may not obey the UEs wish to be down switched by the fast dormancy request.
