Abstract

A mobile communication system including an MBMS cell supporting PTM transmission of MBMS data and a non-MBMS cell not supporting PTM transmission of the MBMS data, includes a user terminal that establishes a connection with the non-MBMS cell. The user terminal transmits an MBMS interest notification indicating that the user terminal desires to receive the MBMS data, to the non-MBMS cell.

Claims

1-11. -11. (canceled)

12. A user terminal in a mobile communication system including an MBMS cell supporting PTM transmission of MBMS data and a non-MBMS cell not supporting PTM transmission of the MBMS data, comprising

a transmitter that transmits an MBMS interest notification indicating that the user terminal desires to receive the MBMS data to the non-MBMS cell, in a case where the user terminal has been established a connection with the non-MBMS cell.

13. The user terminal according to claim 12, wherein

the MBMS interest notification includes information indicating a frequency in which the user terminal desires to receive the MBMS data.

14. A user terminal in a mobile communication system including an MBMS cell supporting PTM transmission of MBMS data and a non-MBMS cell not supporting PTM transmission of the MBMS data, comprising

a transmitter that transmits, to the MBMS cell, an MBMS interest notification about a change of a reception of the MBMS data transmitted from the MBMS cell, when the user terminal changes the reception of the MBMS data in a case where the user terminal has been established a connection with the MBMS cell.

15. A base station in a mobile communication system, comprising

a controller that performs a preparation of a handover of a user terminal to a target base station, wherein

the controller transmits an MBMS interest notification indicating that the user terminal desires to receive the MBMS data, to the target base station, in the preparation of the handover.

16. The base station according to claim 15, wherein

when the controller transmits a handover request to the target base station in the preparation of the handover, the controller includes the MBMS interest notification in the handover request.
