Wireless communication system for routing emergency calls from a VoIP network
First Claim
1. A method of operating a wireless communication system comprising:
- receiving an emergency call request from a Voice over Internet Protocol (VoIP) communication network initiated by a VoIP communication client operating on the VoIP communication network;
processing the emergency call request to determine a wireless device associated with the VoIP communication client;
transferring a message to the wireless device requesting confirmation that a user associated with a emergency call is in possession of the wireless communication device;
in response to receiving the confirmation that the user is in possession of the wireless device, determining a location of the wireless device and determining a public safety answering point (PSAP) based on the location of the wireless device;
if the confirmation is not received, then determining a probability that the user associated with the emergency call is in possession of the wireless device;
if the probability is above a threshold, then determining the location of the wireless device and determining the PSAP based on the location of the wireless device;
if the probability is below the threshold, then determining the PSAP based on a default location; and
establishing the emergency call between the VoIP communication client and the PSAP via the wireless communication system and the VoIP communication network.

9. A communication gateway system in a wireless communication system comprising:
-
a communication interface configured to receive an emergency call request from a Voice over Internet Protocol (VoIP) communication network initiated by a VoIP communication client operating on the VoIP communication network; a processing system configured to process the emergency call request to determine a wireless device associated with the VoIP communication client; the communication interface configured to transfer a message to the associated wireless device requesting confirmation that a user associated with an emergency call is in possession of the wireless device and receive a response from the wireless device confirming that the user is in possession of the wireless communication device; if the confirmation that the user is in possession of the wireless device is received, then the processing system is configured to determine a location of the wireless device, and determine a public safety answering point (PSAP) based on the location of the wireless device; if the confirmation is not received, then the processing system is configured to determine a probability that the user associated with the emergency call is in possession of the wireless communication device, and if the probability is below a threshold then, the processing system is configured to determine the PSAP based on a default location; and the communication interface further configured to establish the emergency call between the VoIP communication client and the PSAP via the wireless communication system and the VoIP communication network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
