Re: [Ecrit] country specific emergency URNs

["Aleksiev, Vasil" <[e-mail]>]

Henning,
In one country always there is a regulator commission which is monitoring the telecom carriers. The regulator issues rules in written form and monitors if all the carriers are following it. If the written rules are not followed, the regulator issues the respective penalties. So every mobile or fixed operator looks into the written rules and takes care of it. In this sense the telecom operators are only caring what is the regulator definition of emergency calls. That is why we have created a file with links to the respective documents, which are issued by the regulators in the respective countries (in form of law). In such document there is definition for emergency calls and list is present with the numbers considered as emergency in the country. The definition usually includes serving the calls with priority, providing location of the subscribers, providing possibility for call back.
One operator uses such mechanisms only for numbers defined as emergency by the law. Of course every organisation is free to define its own emergency number for some reasons, but the operators do not have an obligation to take care of this and route such numbers as normal calls.
I think there is no reason to search in google for every possible emergency number which nobody is routing as emergency according to the regulators requirements.

Vasil,

the service URN does not prescribe any network priority treatment. Indeed, at least in the US, landline 911 calls are treated exactly the same as regular calls, e.g., during network congestion. (We have the SIP RPH mechanism for prioritizing call treatment, but it's not used for civilian emergency calls.)

I suspect this is try for many of the non-112 calls today. I very much doubt that marine emergency calls in Finland or 1-800 calls to the poison control center in the US (and the equivalent set of numbers in Germany, say) receive any priority treatment in the network.

Again, I think it helps make progress if we do not overload labels with policy.

Naturally, any country or carrier is free to use any label, including the URN, to signify any treatment local law and regulation permits or requires. But the label does not require or imply such network treatment.

I admit I'm thoroughly confused by this discussion. Where did the priority issue suddenly come from? It's not in any ECRIT document that I'm aware of.

Hi Brian,
A service URN with a top-level service type of "sos" is used only when the user intends to establish an emergency call. The emergency call will be treated with priority in the network. For non-emergency numbers in one country sos shall not be used since priority there is not needed.

Best regards,

Vasil

Vasil

Once again, the name has no significance as long as it is unique.  We use the names as suggestive for the service to aid the service providers, regulators and public safety authorities in setting up the systems, but the urn name is not used by anything other than computer software during an emergency.

If one country has a service for an ambulance service that is considered an emergency service, but in another country it is not considered an emergency service, we can, and should still use the service in the sos tree for the non-emergency service.  On the other hand, if there was a country that had two ambulance services, one that was used for emergency transport and another that was used for non-emergency transport, then we would need two URNs, because we have distinct services and need different URNs.
