1 Overview To place an emergency call over the Internet, the following information is necessary (additionally to an Internet connection): Location Information: Location information is the fundamental information for an emergency call. Without location information, an emergency call over the Internet is completely impossible. Location information is necessary to determine the responsible PSAP and to plan a response to the emergency. Local Emergency dial strings: Emergency calls are detected by a sequence of dialed numbers, so all local emergency dial strings have to be known.
It is almost certain, however, that the current list of Service URNs does not cover all available emergency services worldwide. For example, there is no registration for an emergency service for forest ﬁres (which have their own emergency service in Greece, Italy, and Portugal) or electrical emergencies (Ireland, Egypt, Israel, and Indonesia). Furthermore, some countries also have multiple different police units; this distinction cannot be made with the current set of Service URNs. In conclusion, it is important to mention that these Service URNs are not intended to be visible to users at all.
A video call can also be used to instruct the caller in how to apply ﬁrst aid. 3 The Role of Location Information Location information is not just a nice-to-have feature for VoIP emergency calls that slightly eases the work at the PSAP. Location information is the key element that enables emergency calls in the ﬁrst place – not only for VoIP-based emergency calling, but also in the traditional telephony system. Since call takers at PSAPs typically ask the caller for his current location, one wonders why location information needs to be provided automatically.
