1. A method for resuming a connection in a user equipment (UE), the method comprising:
sending a Radio Resource Control (RRC) resume request to a network node to initiate an RRC connection resume procedure;
starting a timer for the RRC connection resume procedure, wherein an expiration of the timer stops the RRC connection resume procedure for the UE;
stopping the timer upon one of the following:
the UE receiving a suspend message; and
the UE receiving a release message; and
in response to stopping the timer upon the UE receiving the suspend message:
delaying, for a first period of time, actions which the UE is to execute after receiving the suspend message;
indicating a suspension of the RRC connection resume procedure to upper layers; and
configuring lower layers to suspend an integrity protection.
