SOS and other URNs

H. Schulzrinne in “A Uniform Resource Name (URN) for Emergency and Other Well-Known Services” RFC 5031 describes a service URN scheme for context-dependent services.

Just a dialing 911 in North America or 112 in Europe is mapped to the local emergency services “address”, there are other well known services that could be supported by having a well-known URN to be used with SIP.

These can be combined with Location-to-Service Translation protocol (LoST), RFC 5222 to map the URN to the local instance of the “address”.

Examples:

urn:service:sos
urn:service:sos.ambulance
urn:service:sos.fire
urn:service:sos.police

Transcript

[slide514] Another thing, Henning Schulzrinne has written an RFC about using uniform resource names for emergency and other well-known services. So that now you have URNs for service SOS, or service ambulance, or fire, police, or whatever. What's the advantage of URNs? What does it give you? It gives you a name, which means we can do a mapping of name to the service that actually delivers that. So the result is I can always send it to that name, and now it's up to a server to do the mapping from that to the local ambulance service, or to the local police department, or the fire department. And that is expected to be very powerful.
