Abstract
A network and method to establish a real-time location based service for client mobile device users. Asynchronous data connections are established between client mobile devices and a data server over wireless networks. Synchronous data connections are established between the client devices and a map server over wireless networks. The data server receives geographic location information from the client devices, indicating a geographic location of each client device, and relays the geographic location information to the client devices in real time via the asynchronous data connections. The map server provides map data to the client devices as requested from the client devices via the synchronous data connections. The geographic location information may be overlaid onto the map data and displayed on any of the client mobile devices to indicate the various locations of the various client devices in real time.
