Abstract(in Japanese) (See Japanese page)
Abstract(in English) Mobile personal communications systems in the future require microcellular systems in urban areas,where one of the important technical issues will be how to handle a highly mobile communication traffic within such small cells.In this report, functions of a handover of a portable terminal between microcells are classified into two independent functions.Then,two new channel control schemes for call handovers are presented,which utilize macro-diversity-like transmission, reception techniques.Computer simulations based on an urban microcellular environment(radio propagation,traffic characteristics,etc.)show that the number of handovers per call and the forced termination rate can be decreassed with these schemes.
