Abstract:
A radio terminal operation data write method in a private mobile communication system including a multi-node PBX having a plurality of node exchanges connected to each other through a high-speed data line, comprising:the step of causing a maintenance terminal connected to a first node exchange of said plurality of node exchanges to designate a logical extension number unique in said multi-node PBX and added to a radio terminal with respect to said first node exchange and request said radio terminal to write terminal operation data by radio; the step of causing said first node exchange to refer to a self-network database module holding data common in said multi-node PBX in accordance with the logical extension number so as to specify a third node exchange of said plurality of node exchanges in which the radio terminal operation data is registered; the current location area node specifying step of causing said first node exchange to refer to a current information memory of said radio terminal of said third node exchange directly when said third node exchange coincides with said first node exchange or through the high-speed data line when said third node exchange differs from said first node exchange, thereby specifying a second node exchange of said plurality of node exchanges which corresponds to an area where said radio terminal is currently present; the step of causing said first node exchange to output, to said second node exchange, a request to write operation data in said radio terminal by radio with the logical extension number being added to the request when said second node exchange differs from said first node exchange; the step of causing said second node exchange to specify said third node exchange by referring to said self-network database module in accordance with the logical extension number; the step of reading out data to be written in said radio terminal from operation data on said radio terminal held by said third node exchange directly when said second node exchange coincides with said third node exchange or through the high-speed data line when said second node exchange differs from said third node exchange; the data write step of connecting said second node exchange to said radio terminal by radio and writing the data to be written in said radio terminal; the step of causing said second node exchange to notify said first node exchange of a normal/abnormal end of the write processing when said second node exchange differs from said first node exchange; and the step of causing said first node exchange to notify said maintenance terminal of the normal/abnormal end.
