Abstract (en)

A plurality of first radio communication units (121-12N) having communication mode enabling direct communication between terminals using a radio channel not through a public telephone network are disposed in a plurality of distributed data generation sources (111-11N). A second radio communication unit (31) having the direct communication mode and public mode is disposed within a radio zone formed by a base station (21). The plurality of the first radio communication units (121-12N) or the first radio communication units (121-12N) and the second radio communication unit (31) are connected through a first radio channel using the direct communication mode. The second radio communication unit (31) and the base station (21) are connected through a second radio channel using the public mode. Data generated from a plurality of data generation sources (111-11N) is transmitted from the first radio communication units (121-12N) to the second radio communication unit (31) through the first radio communication channel are transmitted from the second radio communication unit (31) to the center unit (51) through a second radio communication channel via the base station (21) and external communication network (43) and accumulates in the center unit (51). <IMAGE>
