Principles of the GIS service

Hi dear,

The GIS service networking is as follow:

·        On an enterprise network, the GIS function is implemented by the dispatching system, terminals, and GIS server.

·        After the eDC subscribes to the terminals whose GPS switches are turned on, if the GIS report function on the eUDC660 Management System is selected, the terminals start to search for satellite signals. The terminal reports its GIS information to a GIS server using short data channels. The GIS server identifies the eDC to which the terminal is subscribed and forwards the GIS information of the terminal to it. In this manner, a dispatcher can locate the terminal on the GIS map of the eDC. In addition, when a special event (such as an emergency call) occurs, the GPS report switch of the terminal will be turned on automatically, triggering a GIS report.

·        The GIS server delivers GISCFG parameters to the terminal. Configure GIS parameters (GIS report interval and GIS reported distance interval) on the eUDC.

·        Query the GIS subscription information on the WebUI.
