Data communications method and mobile communications system
First Claim
1. A data communications method executed in a communications system, comprising:
- transmitting broadcast data and individual communications data, by a base station that alters a frequency bandwidth over which the broadcast data for providing a point-to-multipoint broadcasting communications service is transmitted and over which the individual communications data for providing a point-to-point individual communications service is transmitted;
receiving at least the broadcast data by a mobile terminal that alters a frequency band over which the broadcast data and the individual communications data transmitted from said base station is received; and
performing decision processing of making a decision as to whether said mobile terminal can receive reception-desired content it desires to receive among contents provided by the point-to-multipoint broadcasting communications service, the decision processing being performed in accordance with a frequency bandwidth and a center frequency of said frequency bandwidth, which are both used for transmitting the reception-desired content.

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.
