METHOD FOR CONTROLLING MOBILE COMMUNICATION DEVICE, method for controlling data exchange initiated automatically in communication system and mobile communication device

摘要

FIELD: communication. SUBSTANCE: system includes assemblage of mobile devices 24 established communication with control station 29. Data exchange takes place between control station 29 and mobile devices 24 and system receives information on location of mobile devices. The latter initiate such communication automatically in turn. Control station 29 sends data determining ordered servicing zones to mobile devices. Mobile devices are located in ordered servicing zones if these zones were specified beforehand but mobile objects move freely. Control station 29 sends broadcast signals to geographically distant cells. Broadcast signals include present data identifying servicing zones covered by cells. Mobile devices 24 automatically initiates information exchange when their specified ordered servicing zone do not match servicing zones for broadcast signals which they can receive. EFFECT: enhanced reliability. 1 dwg
