Mobile communication system, control station, base station, communication method and program

摘要

A mobile communication system according to the present invention is a mobile communication system including base stations each of which forms a cell and transmits MBMS data to a mobile station existing in the cell, and control stations each of which controls the base station connected thereto, wherein the control stations include at least a control station and a second control station that determines a frequency and timing for transmitting the MBMS data in the cell and instructs the first control station of the determined frequency and timing, and wherein each of the first and second control stations establishes time synchronization with another control station and instructs the connected base station to set the cell to the frequency determined by the second control station and transmits the MBMS data to the connected base station in accordance with the transmission timing determined by the second control station.

主权项

1. A mobile communication system comprising:
a mobile station; and a first base station which transmits Multimedia Broadcast Multicast Service (MBMS) data to the mobile station, wherein the first base station receives information related to Multicast Broadcast Single Frequency Network (MBSFN) from a second base station using a X2 interface, wherein the information related to the MBSFN comprises a parameter of a radio resource, and wherein the first base station sends the MBMS data to the mobile station using the parameter of the radio resource included in the information related to the MBSFN, and wherein the mobile station receives the MBMS data, and wherein the information related to the MBSFN is included in a message to exchange configuration data needed for the first base station and the second base station to interoperate over the X2 interface.
