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 suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.
