On suspension of an RRC connection, RRC connection information may be stored and used to re-establish the suspended RRC connection. The RRC connection information can be stored at the UE and/or the RAN node or some other network element. In order to re-establish the RRC connection, the mobile device (101) in one example sends a connection re-establishment request message to the RAN (102) to have the suspended RRC connection re-established. The RAN node may need to attempt to retrieve the RRC connection data (either from memory or if from another network element if stored elsewhere/if the RRC connection was suspended by another RAN node) and verifies whether the RRC connection is valid. When verified, the mobile device (101) receives, in response to the connection re-establishment request message, a connection re-establishment command message from the RAN (102).
