ENHANCED NODE B AND METHOD FOR RRC CONNECTION ESTABLISHMENT FOR SMALL DATA TRANSFERS

摘要

Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send 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.

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.
