Method and apparatus of providing emergency communication services

摘要

Disclosed is an electrical device and method of automatically searching for and connecting to known or unknown available public communication infrastructure and/or devices in the vicinity using a multi-layer communication model. Each layer may include binding information for local available communication methods and shareable hardware devices, a routing table, and, if applicable, one or more logon profiles for service providers. Communication layers may be built by searching for available public communication infrastructure and/or devices in the vicinity by actively sending out connection requests to all addressable destinations along the available transport medium. Each node is able to access and use the communication infrastructure of each other node. Switching between layers as they become inoperable and/or become available without any user interaction required is also possible.

主权项

1. A method, comprising:
transmitting, via a transmitter, connection request packets to all addressable destinations via an accessible transport medium of a wired or a radio network; searching for at least one of an available public communication infrastructure and devices in a corresponding vicinity; receiving at least one response from at least one device in the corresponding vicinity; connecting to the at least one device associated with the at least one response; responsive to receiving that at least one response, spontaneously creating a local area network (LAN) comprising at least two nodes one of which being the at least one device found in the corresponding vicinity and one of which being a primary device, each of the nodes of the LAN exchanging authentication information with one another of said nodes, and sharing their respective resources with the other nodes of the LAN by permitting each of said nodes to access and use an established communication infrastructure of other of said nodes; creating a communication layer via the primary device by incrementing a number representing at least one of a network address, a telephone number and a frequency; creating a connection request comprising the incremented number; and transmitting the connection request onto the communication layer to produce at least one successful response.
