Abstract
A method mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC)connection. In some examples the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101) in response to the connection suspend command message suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspensionRRC connection information is stored and can be 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 mobiledevice (101) receives in response to the connection re-establishment request message a connection re- establishment command message from the RAN (102). In response to the connection re-establishment command message the mobile device (101) re-establishesthe RRC connection with the RAN (102) using the stored RRC connection informationand sends a connection re-establishment complete message to the RAN (102). The mobile device (101) and RAN (102)maythen resume user plane data communication with each other.
