<p>In an MBMS transmission dedicated cell, only a downlink is provided and no uplink is provided. A method of transmitting a paging signal to a mobile terminal in this MBMS dedicated cell is established. A communication system has three types of cells including, in addition to the MBMS dedicated cell, a unicast cell to and from which a mobile terminal can transmit and receive dedicated communication data, and a unicast/MBMS-mixed cell which can provide both a service provided by the unicast cell and a service provided by the MBMS dedicated cell. While receiving the broadcast type data transmitted from the MBMS dedicated cell, the mobile terminal makes a notification of an MBMS receiving state via the unicast cell or the unicast/MBMS-mixed cell to transmit information for identifying the MBMS dedicated cell which is transmitting the broadcast type data which the mobile terminal is receiving, and the communication system transmits a paging signal to the mobile terminal currently receiving the broadcast type data transmitted from the MBMS dedicated cell on the basis of a tracking area (Tracking Area) in which the mobile terminal is tracked, the tracking area being determined on the basis of the information transmitted.</p> |
