发明名称 LOCATION DETERMINATION FOR MOBILE DEVICES IN EMERGENCY SITUATIONS
摘要 An emergency locator component for a mobile communication device enables the mobile communication device to obtain location information from other neighbouring mobile devices in the event that the mobile communication device is unable to determine its own location. The mobile communication device employs a short-range radiofrequency transceiver to broadcast a request for location information to the neighbouring mobile devices. A response containing location information may be received from another mobile device equipped with a similar emergency locator component. Accordingly, this technology enables mobile devices to exchange location information by setting up an ad-hoc network. The location information can be included, for example, in an emergency phone call to an emergency services call center.
