Abstract:
1. A mobile communication system that performs handover control, when any of UEs moves to an adjoining cell, over those UEs, comprising in each of said UEs: means of measuring the reception quality of a dedicated physical channel allocated, together with a common pilot channel over which common transmission takes place within the cell, for communication use to each of said UEs; means of determining a handover destination cell on the basis of the result of that measurement; means of determining whether or not communication quality after rake synthesis satisfies a requirement for quality; means, in said handover control, of searching for a cell needed for obtaining required communication quality by switching during communication said handover destination cell; means of, in said handover control, excluding from said handover destination cells any handover destination cell that does not conform to a power control request transmitted from said UE during communication; means of, in said handover control, measuring during communication the reception quality of said dedicated physical channel for each of said handover destination cells; means of temporarily cutting off communication with any cell whose dedicated physical channel has been measured to be poor in reception quality, wherein each of said UEs further includes means of, in said handover control, excluding from said handover destination cells any handover destination cell whose temporary communication cut-off during communication would not affect communication quality after rake synthesis.
