Patent ID: 8666357

Claim:
In a system for communicating emergency messages that includes wireless communication devices, the system comprising: a device incorporating at least one emergency message transceiver having a first identification code and configured to generate an emergency message, and a cellular transceiver configured to communicate with a cellular communication network, and a transceiver network, the transceiver network further comprising: a plurality of network transceivers, each network transceiver having a unique identification code and configured to communicate the emergency message with other network transceivers over a predetermined path selected from a plurality of possible paths, wherein each network transceiver is configured to communicate the emergency message to other network transceivers if it is in the predetermined path for the message; at least one transceiver unit configured to communicate the emergency message with at least one of the network transceivers; and at least one site controller coupled to the transceiver unit, the site controller configured to communicate the emergency message between the transceiver unit and an intermediary communication system such that the emergency message is communicated with an emergency message management controller coupled to the intermediary communication system, and wherein the site controller is further configured to redefine communication paths when failure of a network transceiver along the predetermined path is detected and transmit path information for a redefined path to one or more transceivers in the network.
