Claim Text:
1. A method, implemented in a user equipment (UE) for use with a Radio Access Network (RAN), comprising: the UE suspending an established RRC connection with the RAN, wherein the suspending causes the established RRC connection to be a suspended RRC connection that disables user plane data communications between the UE and the RAN, the suspended RRC connection maintaining the UE in an RRC connected mode; the UE storing RRC connection data related to the established RRC connection; the UE monitoring, whilst the established RRC connection is suspended, for at least one of: paging and notifications of downlink data for the UE; and the UE determining whether or not the suspended RRC connection is still valid by reference to the RRC connection data stored at the UE, said RRC connection data being usable by the UE to reactivate the suspended RRC connection.
