Abstract
Methods and architectures for improving operation of 9-1-1 and other emergency services networks. Enriched data (e.g., text messages, videos, phase II location information, etc.) may be transmitted to a PSAP via a secondary communication channel (i.e., data), wherein the primary communication channel is a voice telephony trunk. Disclosed embodiments may increase the speed with which accurate location information is made available to improve call routing accuracy and decrease dispatch time. Some embodiments may also enable continued operation of legacy emergency services systems during and after transition to next generation systems.
Claims15
A method for use in provisioning location information in a communications network, comprising:
- obtaining first mobile unit location information, separate from any wireless network cell antenna location information, for a mobile unit;
- provisioning, substantially at call time, said first mobile unit location information to a call routing center, wherein said mobile unit is a data network unit and said call routing center is a selective router adapted for routing wireless telephony network calls;
- and
- operating said call routing center to route a call between said mobile unit and a call answering center using said first mobile unit location information, wherein said provisioning comprises operationally interposing a positioning center between a Voice over Internet Protocol (VoIP) gateway associated with said mobile unit and said call routing center, and operating said positioning center to obtain said first mobile unit location information and provide said first mobile unit location information to said routing center.
A system for use in provisioning location information in a communications network, comprising:
- a positioning center for obtaining first mobile unit location information, separate from any wireless network cell antenna location information, for a mobile unit, said location information being obtained from a source independent of the communications network infrastructure;
- a call routing center to route a call between said mobile unit and a call answering center using said first mobile unit location information, wherein said mobile unit is a data network unit and said call routing center is a selective router adapted for routing wireless telephony network calls;
- and
- and a data network pathway for provisioning, substantially at call time, said first mobile unit location information to said call routing center, wherein said positioning center is operatively interposed between a VoIP gateway associated with said mobile unit and said call routing center, wherein said positioning center is operative to obtain said first mobile unit location information and provide said first mobile unit location information to said routing center.
