    摘要: Embodiments disclosed herein provide systems and methods for providing Voice over Internet Protocol (VoIP) emergency calls via a wireless communication network. In a particular embodiment, a method provides receiving an emergency call request from a VoIP communication network initiated by a VoIP communication client operating on the VoIP communication network. The method further provides processing the emergency call request to determine a wireless device associated with the VoIP communication client. The method further provides determining a location of the wireless device and determining a public safety answering point (PSAP) based on the location of the wireless device. The method further provides establishing an emergency call between the VoIP communication client and the PSAP via the wireless communication system and the VoIP communication network based on the location of the wireless device.

    摘要: A communication system comprises a voice over internet protocol (VoIP) service system and a location determination system. The VoIP service system is configured to receive a call request for an emergency service from a user, process the call request to determine a wireless communication device identifier associated with the user, and transfer a location request for delivery to a location determination system in a wireless network serving the wireless communication device. The location determination system is configured to receive the location request, process the location request to determine a location of the wireless communication device and a possession confidence metric that indicates a level of confidence that the user is in possession of the wireless communication device, and transfer a location response for delivery to the VoIP service system. The VoIP service system is configured to, if the possession confidence metric exceeds a threshold, transfer the call request for the emergency service for delivery to an emergency service provider that serves the location.
