Location-based service network for mobile emergency management is constructed according to the application requirements and specific features of border public safety and emergency responding. The network realizes mobile emergency monitoring and commanding based on the Beidou terminal, GPS terminal, intelligent PDA, Beidou satellite communication networks, and China GSM network. Beidou vehicle -type receiver is used as the access module in the service center (instead of Beidou command -type receiver) to receive other Beidou terminals' location and information, in order to reduce the Beidou networking applications cost. The location and information fusing and exchanging technology between Beidou terminal and GPS terminal is developed and the networking method is studied to realize the functions such as task forcing, information exchanging, neighborhood location exchanging, command dispatching, etc.. So the personnel, vehicles, and materials can be monitored in none ground mobile communication signal coverage areas (such as deserts, Gobi, border, etc.). In the emergency location -based service network, PDA terminals can communicate with Beidou terminals, and can monitor and command other GPS and Beidou terminals based on mobile GIS. The network provides the viable solution for emergency management, which in face of the problems of location sharing, team coopeiation, and mobile commanding in the accident and disaster site. The system and technology has been used in X divisions of the Xinjiang Production and Construction Corps. The trial run shows that the systems and technology can meet the basic needs of the border emergency response, and has good flexibility, high cost-effective and good replicability.
