Patent ID: 7016680

Claim:
Detection for rapid moving of a mobile communication terminal that can change criteria for reselection of a cell to be criteria for switching a local station in association with a result of determining whether or not the mobile communication terminal is moving at a high speed, and compare a result of measuring qualities of radio signals with the criteria for reselection of a cell to switch a cell to be the local station, characterized in that: the mobile communication terminal determines whether or not a cell selected as the local station is registered in a predetermined list when the mobile communication terminal reselects the cell to be the local station; if it is determined that the cell is not registered, the mobile communication terminal registers the cell selected as the local station in said list; when a predetermined measurement terminal time elapses, the mobile communication terminal determines whether or not the number of cells registered in said list exceeds a predetermined threshold value; and if it is determined that the number of cells exceeds the threshold value, considering that the mobile communication terminal is moving at a high speed, the mobile communication terminal changes criteria for reselection of a cell from criteria for preferentially reselecting a cell with relatively narrow coverage to criteria for preferentially reselecting a cell with relatively wide coverage.
