A Uniform Resource Name (URN) for Emergency and Other Well-Known Services
Henning G. Schulzrinne · 2008
The content of many communication services depends on the context, such as the user's location. We describe a 'service' URN that allows well-known context-dependent services that can be resolved in a distributed manner to be identified. Examples include emergency services, directory assistance, and call-before-you-dig hot lines. [STANDARDS-TRACK]
