METHOD FOR DISTRIBUTED CONTROL OF CALLS IN CONTROL STATION OF INTERNATIONAL MOBILE TELECOMMUNICATION-2000

摘要

PURPOSE: Method for a distributed control of calls in a control station of international mobile telecommunication(IMT)-2000 is provided to reduce a state of a call saturation where call processes are concentrated in a certain processor, by equally allocating the call processes to all processors in the control station. CONSTITUTION: A call process is generated at a control station processor(ACP), and a call request is sent to a call process(BCP00)(1). The BCP00 requests a mobile wireless call service to a mobile switching center(MSC) via a signal connector(ASP)(2), which sets a link between the MSC and BCP00(3). The MSC authenticates a received call, selects the ACP for controlling a call, and sends the information on the ACP and a wireless resource allocation to the ASP(4). The BCP00 allocates a traffic channel element(5) to which a corresponding wireless channel information is transmitted(6). The information for setting the call is sent to a controller(ACPn)(7), which generates a process(ACPn0) and requests a link change(8). The ACPn0 selects a selector and notifies the selection to the selector(9). A control signal is received from a terminal at a selector(10), which separates the received control signal to transfer it to the ACPn0(11).
