Abstract:
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 either with or without 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 whether or not 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) when mobility is to be supported.
