Data communications method and mobile communications system

Abstract

In a communications system including a base station capable of altering a frequency bandwidth which is used for transmitting broadcast data for providing point-to-multipoint broadcasting communications service and which is used for transmitting individual communications data for providing point-to-point individual communications service, and a mobile terminal capable of altering a receivable bandwidth which is used for receiving at least the broadcast data and the individual communications data transmitted from the base station, decision processing of making a decision as to whether the mobile terminal can receive reception-desired content it desires to receive among contents provided by the broadcasting communications service is executed in accordance with a frequency occupying bandwidth used for transmitting the reception-desired content. Thus, the mobile terminal becomes able to make a decision as to whether it can receive particular E-MBMS content considering its own UE position.

1 . (canceled) 
     
     
         2 . A communication method of performing radio communication between a mobile terminal and a base station, the communication method comprising steps of:
 discontinuously transmitting data of a multimedia broadcast multicast service (MBMS); and   discontinuously transmitting synchronization signals,   wherein the data of the MBMS and the synchronization signals are transmitted at different time from each other.   
     
     
         3 . A mobile communication system comprising:
 a mobile terminal; and   a base station that performs radio communication with the mobile terminal, the base station having a first transmitter that discontinuously transmits data of a multimedia broadcast multicast service (MBMS) and a second transmitter that discontinuously transmits synchronization signals,   wherein the first transmitter and the second transmitter transmit the data of the MBMS and the synchronization signals, respectively, at different time from each other.   
     
     
         4 . A base station that performs radio communication with a mobile terminal, the base station comprising:
 a first transmitter that discontinuously transmits data of a multimedia broadcast multicast service (MBMS); and   a second transmitter that discontinuously transmits synchronization signals,   wherein the first transmitter and the second transmitter transmit the data of the MBMS and the synchronization signals, respectively, at different time from each other.   
     
     
         5 . A mobile terminal that performs radio communication with a base station, the mobile terminal comprising:
 a first receiver that discontinuously receives data of a multimedia broadcast multicast service (MBMS); and   a second receiver that discontinuously receives synchronization signals,
 wherein the first receiver and the second receiver receive the data of the MBMS and the synchronization signals, respectively, at different time from each other.
