METHOD FOR DETECTING HIGH-SPEED MOVEMENT OF MOBILE COMMUNICATION TERMINAL, MOBILE COMMUNICATION TERMINAL, AND PROGRAM

摘要

A high-speed movement of a mobile communication terminal is properly detected and the cell reselection reference is modified. When a cell reselection is generated, a processing control block searches a cell transition list (step S10) and judges whether the cell selected as a local station by the cell reselection is already registered in the cell transition list (step S11). When it is judged that the cell is not registered, the processing control block registers the cell selected as the local station in the cell transition list (step S12) and increments by 1 the variable N indicating the number of registered cells (step S13). After this, when a predetermined measurement time has elapsed, the processing control block judges whether the variable N exceeds a predetermined threshold value. When the variable N is judged to exceed the predetermined threshold value, it is decided that the mobile communication terminal is rapidly moving and the cell reselection reference is changed from a reference for preferentially reselecting a cell having a comparatively small cover area to a reference for preferentially reselecting a cell having a comparatively large cover area.
