Introduction Table 1 shows the policy for registration of sub-services of the service URN with the 'sos' service type as defined in RFC 5031 [RFC5031] section 4.2. +-------------------------------------------------------------------+ | The 'sos' service type describes emergency services requiring an | | immediate response, typically offered by various branches of the | | government or other public institutions. Additional sub-services | | can be added after expert review and must be of general public | | interest and have a similar emergency nature. The expert is | | designated by the ECRIT working group, its successor, or, in | | their absence, the IESG. The expert review should only approve | | emergency services that are offered widely and in different | | countries, with approximately the same caller expectation in | | terms of services rendered. The 'sos' service is not meant to | | invoke general government, public information, counseling, or | | social services. | +-------------------------------------------------------------------+ Table 1: Excerpt from RFC 5031 section 4.2. Some existing emergency services are offered in one country only. Examples are the "Reporting spies" emergency service offered in South Korea and the "GAULA (anti-kidnapping)" emergency service offered in Colombia according to http://en.wikipedia.org/wiki/Emergency_telephone_number Moreover, emergency services to be defined in future can initially be introduced in one country only. The policy for registration of sub-services of the service URN with the 'sos' service type as shown in Table 1 which requires the emergency service to be "offered widely and in different countries, with approximately the same caller expectation in terms of services rendered" cannot be fulfilled for the emergency services identified above. 2. Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14, RFC 2119 [RFC2119]. Holmberg & Sedlacek Expires August 29, 2013 [Page 3] Internet-Draft country specific emergency services February 2013 3. Definitions Country specific emergency service: an emergency service offered in one country only. 4. Problem statement The policy for registration of sub-services of the service URN with the 'sos' service type as defined in RFC 5031 [RFC5031] prevents registration of a sub-service of the service URN with the 'sos' service type for the country specific emergency service. 5. Requirement REQ-1: It MUST be possible to register with IANA a sub-service of the service URN with the 'sos' service type as defined in RFC 5031 [RFC5031] for the country specific emergency service. 6. Solution 6.1. Service URN assignment A country specific emergency service is identified by the service URN with the 'sos' service type as defined in RFC 5031 [RFC5031] with: o the first sub-service set to 'country-specific'; o the second sub-service identifying the country where the emergency service is deployed. The format of second sub-service is an ISO 3166-1 alpha-2 code as specified in ISO 3166-1; and o the third sub-service uniquely identifying the emergency service in the country where the emergency service is deployed. The value of the third sub-service is assigned by the public safety answering point (PSAP) offering the country specific emergency service. Example: urn:service:sos.country-specific.xy.567 can identify an emergency service identified by an emergency number 567 in a country identified by "xy" ISO 3166-1 alpha-2 code as specified in ISO 3166-1. 6.2. IANA Considerations 6.2.1. 'country-specific' sub-service of the service URN with the 'sos' service type urn:service:sos.country-specific This service identifier has the same Holmberg & Sedlacek Expires August 29, 2013 [Page 4] Internet-Draft country specific emergency services February 2013 semantic as the urn:service:sos. Note: this sub-service is added to enable different registration policies for the country specific emergency services. 6.2.2. country identifying sub-service of the service URN with the 'sos' service type and with the 'country-specific' sub-service service URN with the 'sos' service type, with the 'country-specific' first sub-service and with second sub-service indicating the country identified by ISO 3166-1 alpha-2 code as specified in ISO 3166-1 has the same semantic as the urn:service:sos. IANA is requested to register URN for each country identified by ISO 3166-1 alpha-2 code as specified in ISO 3166-1. Note: this sub-service is added to ensure uniqueness of URNs for the country specific emergency services. 6.2.3. service URN for country specific emergency service A sub-service identifying a country specific emergency service can be added to the service URN with the 'sos' service type, with the 'country-specific' first sub-service and with country identifying second sub-service. The policy for registration of sub-services of the service URN with the 'sos' service type, with the 'country-specific' first sub-service and with country identifying second sub-service is "Expert Review" as defined in RFC 5226 [RFC5226]. The expert review should only approve emergency service that is offered by a public safety answering point (PSAP) in the country identified by the second sub-service of the service URN being registered. The emergency service is not required to be "offered widely and in different countries, with approximately the same caller expectation in terms of services rendered". The expert is designated by the ECRIT working group, its successor, or, in their absence, the IESG. 7.
