1. A method in a user equipment (UE) for controlling transmissions, the method comprising:
activating, in response to a first system information message received from a radio access network (RAN) via a radio interface and a mobile-originated access request, a timer for applying access control to transmissions for a certain access category during an access control period;
receiving, via the radio interface and while the timer is running, a second message that indicates a potential transition of the UE from a current cell to a new cell; and
in response to receiving the second message:
stopping the timer, using a radio resource control RRC entity of the UE, prior to expiration of the access control period,
sending, from the RRC entity to a non-access stratum NAS entity of the UE, a notification of alleviation of the access control for the access category,
receiving, at the RRC entity from the NAS entity, after the sending of the notification of alleviation, a request to check alleviation of the access control for the access category, and
determining whether to apply the access control to the transmissions for the access category, for a remainder of the access control period, in accordance with a result of the checking.
