1. A method performed by an enhanced node B (eNB) for small-data radio-resource control (RRC) connection establishment in a 3GPP LTE network, the method comprising:

  • receiving a small-data RRC connection request message from user equipment (UE), the small-data RRC connection request message including an establishment clause value indicating small-data traffic with mobility;

    sending an initial UE setup request message to inform a mobility management entity (MME) that a small-data RRC connection for the UE is being established;

    indicating to the MME that the small-data RRC connection is to be established with mobility;

    receiving an acceptance message from the MME for the small-data RRC connection, the acceptance message including a reduction of an RRC inactivity timer for fast connection release; and

    sending an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) as part of support for mobility.
