ABSTRACT:
The present invention provides a mobile communication system capable of effectively utilizing the limited reception resources available to the UEs and thereby performing steady communication for use in the handover control of UEs. A UE, during communication, determines a handover destination cell according to the result of measurement of the CPICH reception level of each of cells: (1) it measures the reception quality of the downlink DPCH of each of the cells and utilizes the result for the selection of the handover destination cell; (2) switches the handover destination cell and searches for a cell needed for obtaining required communication quality; (3) observes the displacement of the CPICH path loss of each of the cells; and (4) observes whether or not the downlink DPCH transmission power is controlled on the basis of the power request from the UE for each of the handover destination cells.
