Patent ID: 8542611

Claim:
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.
