System and method for initiating an emergency call from a device to an emergency call processing system
First Claim
1. A method for dynamically building and maintaining call priority information for use in emergency calls from a client device to an emergency call center, the method comprising the steps of:
- providing a plurality of communication connections operable on at least one communication system, each of the plurality of communication connections corresponding to a plurality of bearer services and comprising a plurality of metrics;
determining by the client device which of the plurality of communication connections is active;
evaluating each of the plurality of metrics for each of the active communication connections; and
ordering sequentially the plurality of active communication connections based on at least one of the plurality of evaluated metrics.

Abstract
A method for dynamically building and maintaining call priority information for use in emergency calls from a client device to an emergency call center is provided. The method provides a plurality of communication connections operable on at least one communication system, and each of the plurality of communication link comprises a plurality of metrics. The method further determines by the client device whether each of the plurality of communication connections is active, and evaluates each of the plurality of metrics for each of the active communication connections, and orders sequentially the plurality of active communication connections based on at least one of the plurality of evaluated metrics.

10. A method for communicating an emergency call from a client device to a service center, the method comprising the steps of:
-
providing a sequentially ordered plurality of communication connections, the plurality of communication connections corresponding to a plurality of bearer services;
attempting to transmit the emergency call over a first communication connection selected from the prioritized plurality of communication connections;
determining whether the emergency call was successfully transmitted to and received by the service center over the first communication connection;
attempting to transmit the emergency call over a second communication connection selected from the sequentially ordered plurality of communication connections if the service center did not receive the emergency message transmitted over the first communication connection;
determining whether the emergency call was successfully transmitted to and received by the service center over the second communication connection; and
sequentially traversing the plurality of communication connections until the emergency call is successfully transmitted to and received by the service center. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus for use in communication of emergency calls to a service center, the apparatus comprising:
-
a microcomputer operable to communicate information with the service center;
a plurality of wireless units, each in communication with the microcomputer and operable to transmit and receive information over a plurality of communication connections;
a modem in communication with the microcomputer and operable to support communication of information over analog wireless networks;
an emergency button in communication with the microcomputer and operable to initiate a generation of the emergency calls;
a position unit in communication with the microcomputer and operable to determine and report a position of the apparatus or a physical host of the apparatus; and
communication units in communication with the microcomputer and operable to provide and receive audio and visual information from a user.
