An emergency routing protocol within a wireless communication network. A mobile device can establish a communication link to the system backbone even when, for whatever reason, it can no longer communicate directly with a base station. The emergency routing protocol enables a distressed mobile device to communicate with the system backbone through another mobile device serving as an intermediary. The intermediary mobile device forwards information destined to/received from the distressed mobile device to its intended destination.

[ What is claimed is:] [1.] An emergency routing method in a wireless communication system including a system backbone, a plurality of mobile devices, and one or more base stations coupled to the system backbone, the plurality of mobile devices being configured to move about the system and to communicate wirelessly with the system backbone by way of the one or more base stations, the emergency routing method comprising the steps of:(a) a first mobile device among the plurality of mobile devices attempting to communicate with the system backbone by communicating wirelessly and directly with any of the one or more base stations;(b) determining by the first mobile device whether the first mobile device is able to communicate directly with any of the one or more base stations; and(c) in the event the first mobile device is unable to communicate directly with any of the one or more base stations, the first mobile device establishing a wireless communication link with any of the one or more base stations using a second mobile device from among the plurality of mobile devices as an intermediary for communications between the first mobile device and the any of the one or more base stations.
