An IP based platform for emergency calls and reporting

Most operators and providers have elected to migrate from circuit-switched networks to packet-switched networks after realizing the tangible benefits, which include convergence, rich services, cheaper maintenance, and user satisfaction. As Next Generation Networks (NGNs) will certainly be the future replacement for current telecommunication networks, it follows that current emergency systems are upgraded as well in order to fulfill the NGN requirements. This paper discusses the development of a daily emergency framework based on the IP Multimedia Subsystem (IMS). We place particular emphasis on caller location retrieval, emergency event reporting, and support for disabled communities. A testbed as well as some appropriate testing scenarios were set up in order to assess the developed mechanisms.
