In one embodiment transmission of at least a first type of traffic to or from a user equipment (UE) is temporarily prohibited in response to an indication from the UE to release a radio connection. Throughout the temporary prohibition, the UE and/or network refrain from running any connection establishment procedure that involves the UE, except to establish a connection for transmission of a different second type of traffic to or from the UE. In specific examples the indication can be RRC connection release assistance information, or it can be implicit such as in an empty buffer status report or a UE request for a battery efficient configuration. The temporary prohibition may hold until expiry of a timer that is initiated when the UE sends the indication or when the RRC connection is released in reply. The first/second types may be normal/high priority and/or normal/exception reporting.
