APPARATUS AND METHOD FOR TRANSMITTING CONTROL INFORMATION FOR CONTINUOUS MBMS SERVICE
First Claim
1. A user equipment (UE), which transmits control information for continuity of a multimedia broadcast multicast service (MBMS) service, as a terminal performing handover from a source base station (BS) (or a source eNB) to a target BS (or a target eNB), the UE comprising:
- a UE reception unit configured to receive a radio resource control (RRC) connection reconfiguration message from the source BS;
a UE processor configured to reconfigure an RRC connection of the UE on the basis of the RRC connection reconfiguration message, and generate an RRC connection reconfiguration complete message including at least one of a flag indicating whether an MBMS service is received and active MBMS service information indicating a type of the MBMS service; and
a UE transmission unit configured to transmit the RRC connection reconfiguration complete message to the target BS.

Abstract
The present specification discloses an apparatus and a method for transmitting control information for a continuous MBMS service. The present specification discloses a terminal comprising: a terminal processor for generating a measurement report related to source and target cells, reconfiguring RRC connections on the basis of an RRC connection reconfiguration message, and generating an RRC reconfiguration completion message comprising a flag indicating whether or not the MBMS service has been received and/or active MBMS service information indicating the type of MBMS service; a terminal transmission part for transmitting the measurement report to the source base station and the RRC connection reconfiguration completion message to the target base station; and a terminal reception part for receiving the RRC connection reconfiguration message from the source base station.

5. A method for transmitting control information for continuity of a multimedia broadcast multicast service (MBMS) service by a user equipment (UE), which performs handover from a source base station (BS) to a target BS, the method comprising:
-
generating a measurement report regarding a source cell and a target cell; transmitting the measurement report to the source BS; receiving a radio resource control (RRC) connection reconfiguration message from the source BS; reconfiguring an RRC connection on the basis of the RRC connection reconfiguration message; generating an RRC connection reconfiguration complete message including at least one of a flag indicating whether an MBMS service is received and active MBMS service information indicating a type of the MBMS service; and transmitting the RRC connection reconfiguration complete message to the target BS. - View Dependent Claims (6, 7, 8)

9. A target base station (BS) to provide continuity of a multimedia broadcast multicast service (MBMS) service with respect to user equipment (UE), the target BS comprising:
-
a target processor configured to generate an MBMS information request message for requesting at least one of information regarding whether the UE receives an MBMS service, information regarding a type of the MBMS service, and information regarding a cell in which the MBMS service is transmitted, from the UE, and to generate an MBMS point-to-multipoint radio bearer (MRB) initiation message indicating that the MBMS service is provided to the UE through an MRB as a bearer for an MBMS; a target transmission unit configured to transmit the MBMS information request message or the MRB initiation message to the UE; and a target reception unit configured to receive an MBMS information response message including at least one of information regarding whether the UE receives an MBMS service, information regarding a type of the MBMS service, and information regarding a cell in which the MBMS service is transmitted, from the UE, as a response with respect to the MBMS information request message. - View Dependent Claims (10, 11, 12)

13. A method for providing continuity of a multimedia broadcast multicast service (MBMS) service by a target base station (BS) with respect to a user equipment (UE), the method comprising:
-
transmitting, to the UE, an MBMS information request message for requesting at least one of information regarding whether the UE receives an MBMS service, information regarding a type of the MBMS service, and information regarding a cell in which the MBMS service is transmitted from the UE; receiving an MBMS information response message including at least one of information regarding whether the UE receives an MBMS service, information regarding a type of the MBMS service, and information regarding a cell in which the MBMS service is transmitted, from the UE, as a response with respect to the MBMS information request message; and transmitting an MBMS point-to-multipoint radio bearer (MRB) initiation message indicating that the MBMS service is provided to the UE through an MRB as a bearer for an MBMS. - View Dependent Claims (14, 15, 16)
