Document Type and Number:
WIPO Patent Application WO/2010/050303
Kind Code:
A1
Abstract:
A mobile communication system comprises a mobile station; base stations each of which forms a cell and transmits MBMS data to the mobile station existing in the cell; and control stations each of which controls a base station connected thereto. The mobile communication system further comprises a core network node that instructs each of the control stations connected thereto with respect to the frequency and timing of transmitting MBMS data in the cell. Each of the control stations establishes a time synchronization with another control station and instructs the connected base station to set the cell to the frequency designated by the core network node and further transmits, to the connected base station, the MBMS data in accordance with the transmission timing designated by the core network node. The mobile station then receives the MBMS data.
