In order to re-establish a suspended 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 message, a connection re-establishment command message from the RAN (102). In response to the message, the mobile device (101) re-establishes the RRC connection with the RAN (102), using the stored RRC connection information, and sends a connection re-establishment complete message to the RAN (102). The mobile device (101) and RAN (102) may then resume user plane data communication with each other.
