Emergency Registries

Internet-Draft	Emergency Registries	December 2021
Rosen & Abley	Expires 25 June 2022	[Page]

Abstract

Multiple emergency services standards organizations are developing standards based on IETF emergency call standards and other IETF protocols. There is a desire among these organizations to use common registries not tied to a particular country or national SDO, in the long term pursuit of a single worldwide standard. This document asks IANA to create a set of registries and provides processes for expanding the set and populating them.¶

4. IANA Considerations

This document creates a number of registries. The initial values for these registries are not defined and will be submitted by regional and international SDOs such as NENA and ETSI.¶

4.1. "emergency" URN namespace

IANA is requested to register a new URN namespace for "emergency".¶

4.1.1. Namespace Identifier

emergency¶

4.1.2. Version

1¶

4.1.3. Date

RFC Editor: please insert the date this RFC was published¶

4.1.4. Registrant

IETF and the ecrit Working Group. Should the working group cease to exist, discussion should be directed to the Applications and Real-Time Area or general IETF discussion forums, or the IESG.¶

4.1.5. Purpose

This namespace is used for unique identifiers for use in emergency services, including emergency calls. Most uses for this identifiers will be used within private "Emergency Services IP Networks" (ESInets), some use in the public Internet is expected. These identifiers will be used in several countries, and hopefully, eventually, worldwide for handling of emergency calls and incidents. Prior to this document, North American emergency services used the "nena" nid, defined in [RFC6061]. Most identifiers in urn:nena will be replaced by identifiers in urn:emergency in pursuit of a single worldwide standard set for emergency services which are not controlled by a single public safety organization like NENA. Identifiers with this nid do not require resolution. Identifiers in this nid will primarily specified in public safety standards SDOs, but some IETF standards may use or define them.¶

4.1.6. Syntax

The basic syntax for identifiers in the emergency nid is:¶

urn:emergency:<top level class>:<:extended>¶

where¶

<top level class> is a member of the urn:emergency namespace registry, see Section 4.4 ¶

<extended> is a class-specific value defined by the document describing the registry entry. In many cases, the extension includes sub classes. For example: urn:emergency:service:responder:police.local¶

There are no special encoding rules for identifiers in urn:emergency. URN equivalence is non-case sensitive. Hyphens are not expected in these identifiers, but if used, they are significant in comparisons. Quotes are not allowed in this nid. There are no special considerations for conforming to URN syntax. Percent encoding is permitted. There are no uses for q-components or f-components in this namespace.¶

4.1.7. Assignment

Assignment of top level classes is by standards documents, both standards-track RFCs and standards documents in other SDOs. See Section 4.4. Assignments within top level classes are defined in the document that defines the class. Such documents MUST specify how uniqueness within the class is achieved.¶

4.1.8. Security and Privacy

Each top level class, in its defining document MUST describe the security and privacy considerations of that class. In general, there are no special security consierations for these identifiers. Several top level classes are defined in this document. In some circumstances, these identifiers may indicate what kind of agency is involved with a public safety incident, and some may identify a specific agency. Encryption of the communications that contain the identifier in classes defined in this document is REQUIRED and MUST be TLS or an equally secure protocol.¶

4.1.9. Interoperability

Many of the identifiers in urn:emergency are similar in construction and use as identifiers originally defined in urn:nena. Backwards compatibility with those identifiers MUST be specified in the documents that use them. NENA STA-010.3-2021 is the primary document that has this backwards compatibility requirement, as it defined most of the identifiers in urn:nena. There are no other interoperability issues.¶

4.1.10. Resolution

No resolution of these identifiers is defined.¶

4.2. "Emergency" Area

IANA is requested to establish the registries within this section under the "Emergency" area. These registries contain enumerated values used for emergency calling. New registries or subregistrues in the "Emergency" area require a standards document, which MAY be a standards track RFC, but also MAY be a defined in a document from a recognized standards organization that promulgates emergency services standards. Where a new registry or subregistry is defined in an external standards organization, an expert SHALL review the document to ascertain that it is relevant to the "Emergency" area, that the organization defining the registry is a recognized standards organization, that the document clearly articulates the management method for the regisry, which MUST be substantially similar to one or more of the management methods in [RFC8216], and if expert review is specified, that experts acceptable to the IESG for the registry are available. The expert reviewing the new registry shall also request IANA to review the relevant documents using the same criteria as it would for a standards track RFC. The expert SHALL NOT approve the new registry unless IANA is satisfied it can maintain the registry with the same or similar level of effort it expends for similar registries created by RFCs. If the management of the registry is specified as First Come First Served, which, per RFC8126 does not require an expert, an expert acceptable to the IESG must be available to answer questions about registrations and advise IANA of any issues in registrations in that registry.¶

These registries are required to implement The NENA i3 Standard for Next-Generation 9-1-1 [NENAi3] as well as the NENA Standard for Emergency Incident Data Object [EIDO]. These standards, unless otherwise specified, will initially populate the registries created by this document. Some registries previously existed in the NENA Registry System [NRS], but the intent of international SDOs is to maintain next-generation emergency calling registries under IANA in the future. [NRS] will be maintained only for backwards compatibility, and for registries required only for North America.¶

4.3. Emergency Call Additional Data Registry

IANA is requested to move the Emergency Call Additional Data registry and its sub-registries to the Emergency Area¶

4.4. "urn:emergency" registry

IANA is requested to create a registry for the emergency nid top level classes in the emergency area.¶

4.4.1. Name

urn:emergency¶

4.4.2. Information Needed to Create a New Value

Name of the top level class, a short description and a reference to a document that defines it.¶

4.4.3. Registration policy

Specification Required [RFC8126], which requires expert review. The specification MUST be from the IETF or a recognized standards organization that creates standards for emergency services. The expert must confirm the requested class is appropriate for emergency services, if the registering organization is not the IETF, that it is an appropriate organization to define the class, that the purpose adequately describes the new class and the reference leads to a document that clearly describes the use of the class. Also see Section 4.4.5 ¶

4.4.4. Content

This registry contains:¶

The ASCII "Name" of the "top level" class (a short string)¶
The ASCII "Purpose" of the label (explanatory text)¶
A "Reference" (URI) to the standard that defines the label¶

4.4.5. Subregistries for top level classes of urn:emergency

In most cases, top level classes of urn:emergency will define subregistries. Several levels of subregistries may be needed. The document that defines the class MUST define the subregistry if needed. IETF and emergency service standards organizations MAY define subregistries of urn:nena. Instructions to IANA for the subregistry MUST conform to [RFC8126]. The expert reviewer for the top level class works with IANA to assure that they do if the standards organization creating the subregistry is not the IETF.¶

4.4.5.1. "urn:emergency:service" Subregistry

IANA is requested to create a subregistry for "urn:emergency:service" under "urn:emergency".¶

When calls are routed within an Emergency Services IP Network (ESInet), the routing element queries a LoST [RFC5222] server for the (nominal) route. It does so with a service URN. Esternal routing is accomplished with "urn:service:sos", as defined by [RFC5031]. Within an ESInet, values under this registry are used.¶

Service URNs as defined here begin with "urn:emergency:service". The sub-namespace defined by this registry MAY be further subdivided (potentially several times), by sub-registries under this sub-registry. The separator between urn:emergency:service and the entry in the subregistry is a colon (":"). A new entry starting with "urn:emergency:service" SHOULD denote a new type of route, which MUST be distinguished by the LoST server from other uses. For example, emergency calls being routed within the ESInet use "urn:emergency:service:sos" (or a subspace of it). Calls routed by a PSAP to a responder use "urn:emergency:service:responder" (the type of responder is also included, e.g., "urn:emergency:service:responder.police"). A client specifies the URN in a LoST query, and the LoST Server uses it to choose a (nominal) route.¶

4.4.5.1.1. Name

urn:emergency:service¶

4.4.5.1.2. Information Needed to Create a New Value

Name of the entry, a short description and a reference to a document that defines it.¶

4.4.5.1.3. Registration policy

Specification Required [RFC8126], which requires expert review. The specification MUST be from the IETF or a recognized standards organization that creates standards for emergency services. The expert must confirm the requested entry is appropriate for emergency services, if the registering organization is not the IETF, that it is an appropriate organization to define the entry, that the purpose adequately describes the new entry and the reference leads to a document that clearly describes the use of the entry. Also see Section 4.4.5 ¶

4.4.5.1.4. Content

This registry contains:¶

The ASCII "Name" of the value (a short string)¶
The ASCII "Purpose" of the value (explanatory text)¶
A "Reference" (URI) to the document that defines the value¶

4.4.5.2. "urn:emergency:service:sos" Subregistry

IANA is requested to creates a subregistry for "urn:emergency:service:sos" under "urn:emergency:service".¶

Routing of emergency calls within the ESInet is a primary function of systems that process such calls. When routing entities must route calls within the ESInet, they query the LoST Server for the route. Routing for emergency calls may involve multiple levels of routing entities. Each level may need a different URN to be distinguishable. Routing of emergency calls, including instant messages and non-interactive calls within an ESInet, is accomplished with a URN beginning with "urn:emergency:service:sos". The "urn:emergency:service:sos" registry contains values appropriate for the various levels of routing within the ESInet. The separator between urn:emergency:service:sos and entry in the subregistry is a colon (":").¶

4.4.5.2.1. Name

urn:emergency:service:sos¶

4.4.5.2.2. Information Needed to Create a New Value

Name of the entry, a short description and a reference to a document that defines it.¶

4.4.5.2.3. Registration policy

4.4.5.2.4. Content

This registry contains:¶

The ASCII "Name" of the service value (a short string)¶
The ASCII "Purpose" of the value (explanatory text)¶
A "Reference" (URI) to the document that defines the value¶

4.4.5.3. "urn:emergency:service:test" Registry

IANA is requested to creates a subregistry for "urn:emergency:service:test" under "urn:emergency:service".¶

Test calls are directed to "urn:service:test.sos". To route such test calls where the routing infrastructure uses multiple levels of routing, and thus uses URNs in the "urn:emergency:service:sos" registry, service URNs are needed for test calls with similar levels. IANA is requested to create an entry in the "urn:emergency:service" registry with the name "test" and with the purpose noted as "routing test calls within the ESInet toward a primary PSAP". The reference will be to the registry created by this section, "urn:emergency:service:test". The separator between the "test" label and the service ("urn:emergency:service:test" registry entry) is a period ".". The "urn:emergency:service:test" registry contains label values corresponding to the levels in the "urn:emergency:service:sos" registry. These registries are normally kept in sync, an entry added to "urn:emergency:service:sos" should also add a corresponding entry to urn:emergency:service:test.¶

4.4.5.3.1. Name

urn:emergency:service:test¶

4.4.5.3.2. Information Needed to Create a New Value

Name of the entry, a short description and a reference to a document that defines it.¶

4.4.5.3.3. Registration policy

Specification Required [RFC8126], which requires expert review. Normally, entries in urn:emergency:service:test mirror those in urn:emergency:service:sos. If there are any discrepancies the expert shall determine if the requested entry meets the use defined above and the specification document adequately describes how the entry is used.¶

4.4.5.3.4. Content

The content of this registry should mirror the content of urn:service:test:sos except with the "test" label as described above.¶

4.4.5.4. "urn:emergency:service:responder" Registry

IANA is requested to create the "urn:emergency:service:responder" subregistry under "urn:emergency:service"¶

Once a PSAP gets a call, they may have to transfer the call to a secondary PSAP. The secondary PSAP is chosen based on the type of responder, and the location of the caller. Routing of emergency calls from a PSAP towards a responder is accomplished with a URN beginning with "urn:emergency:service:responder". IANA is requested to create an entry in the "urn:emergency:service" registry with the name "responder" and with the purpose noted as "routing emergency calls within the ESInet towards a responder". The reference will be to the registry created by this section, "urn:emergency:service:responder".¶

The "urn:emergency:service:responder" registry contains label values appropriate for the types of responders within the ESInet. The separator between the "responder" label and the type of responder ("urn:emergency:service:responder" registry value) is a period ".". This registry is also used in other contexts where an agency type is useful. For those purposes, a 'psap' entry is provided. "urn:emergency:service:responder.psap" must not be used to route emergency calls. It is not equivalent to, or a substitute for "urn:service:sos" or "urn:emergency:service:sos".¶

Some of the entries in this registry will require further subdivision. Subregistries for such divisions are REQUIRED.¶

4.4.5.4.1. Name

urn:emergency:service:responder¶

A "Reference" (URI) to a document that defines the label¶

4.4.5.5. "urn:emergency:service:responder.police" Subregistry

There are many different kinds of law enforcement agencies that have distinct differences in jurisdiction and formation (for example, police department organized under a municipal government as opposed to the sheriff's office organized under an elected sheriff). This subregistry delineates different types of police agenices under the urn:emergency:service:responder:police registry. The separator between urn:emergency:responder.police and the entry in this subregistry is a period (".").¶

4.4.5.5.1. Name

urn:emergency:service:responder.police¶

4.4.5.5.2. Information Needed to Create a New Value

The names used for various kinds of police departments varies from country to country. The expert is requested to try to minimize the number of entries in the registry, but is not expected to have to learn the details of how police forces are organized in any country. An English name is preferred, to match the existing entries¶

4.4.5.5.4. Content

This registry contains:¶

The UTF-8 "Name" of the agency type¶

4.4.5.6. "police.federal" Subregistry

There are several federal police agencies. This registry is a subregistry of "urn:emergency:service:responder.police." and lists each police agency operating at the federal/national level. The "federal.police" registry contains label values appropriate for the types of national police responders within the ESInet. This is distinct from the parent subregistry, "police.federal", is the police.federal subregistry includes the names for specific federal agencies, as opposed to the "responder.police" subregistry which indicated the agency TYPE (police). The separator between the "police.federal" label and the type of responder ("urn:emergency:service:responder.police.federal" registry value) is a period ".".¶

4.4.5.6.1. Name

urn:emergency:service:responder.police.federal¶

4.4.5.9. "urn:emergency:service:serviceAgencyLocator" Subregistry

The ESInet will connect to many services and public safety agencies. A directory ("white pages" and "yellow pages") of agencies, together with key information about the service or agency, is the function of the Service/Agency Locator. The Service/Agency Locator is a distributed database. There are several mechanisms by which the Service/Agency Locator can be searched to locate a specific service or agency. When searching for a service by location, the LoST protocol ([RFC5222] is used, which accepts a URN that specifies the service being searched by location. This registry provides urns to be used witha LoST query to find that service at a particular location.¶

4.4.5.9.1. Name

urn:emergency:service:serviceAgencyLocator¶

The long "Service" name of the service (e.g., "Emergency Services Routing Proxy")¶
A "Reference" with a URI to the document that requested the service.¶

4.4.5.10. "urn:emergency:uid" Registry

Various entities need to create globally unique identifiers. A simple way to do that is to combine a locally unique identifier and a domain name (which is globally unique). However, many entities need to create more than one type of globally unique identifier and knowing what type of identifier is helpful in diagnosing problems. For this purpose, the uid URN subregistry creates unique strings used to prepend identifiers that indicate the type of identifier it is.¶

This document does not describe the structure of the identifier beyond the urn:emergency:uid prefix and the value in this registry. The defining specification MUST describe the structure of the identifier.¶

4.4.5.10.1. Name

The UTF-8 "Purpose" of the identifier prefix¶
A "Reference" with a URI to the document that requested the registry entry.¶

4.4.5.11. "urn:emergency:media-feature" Registry

SIP Media Feature tags as defined in [RFC3840] are used to indicate user agent capabilities. SIP elements inside ESInets use this mechanism to indicate availablity of certain emergency call specific functionality. Since these media feature tags are specific to emergency calling, are primarily defined in non-IETF documents and not used outside an ESInet, they are not appropriate for registration in the SIP Media Feature Tag Registry. This registry provides a similar function to the registry defined in RFC3840. The separator between the "urn:emergency:media-feature" and the content of this registry is a colon (":").¶

4.4.5.11.1. Name

urn:emergency:media-feature¶

4.4.5.11.2. Information Needed to Create a New Value

A short tag, purpose description and a reference to a document that specifies the entry.¶

4.4.5.11.3. Registration policy

Specification Required [RFC8126], which requires expert review. The expert should confirm that entry represents a new type of SIP media feature tag and specifies how it is used.¶

4.4.5.11.4. Content

This registry contains:¶

A short ASCII "Tag"¶
A long ASCII "Purpose"¶
A "Reference" with a URI to the document that requested the registry entry.¶

4.5. Internal Services Registries

The following are additional registries used internally in an ESInet />¶

4.5.1. "serviceNames" Registry

Processing of emergency calls uses a variety of services which are queried either using SIP or HTTP. These services are discoverable through the ESInet that has deployed an instance of these services. In order to faciliate interoperability there is need to codify their names in a registry. IANA is requested creates the ServiceNames registry in the Emergency area.¶

A "Reference" with a URI to the document that defines the state.¶

4.5.4. "SIPHeaderIsOperatorConditions" Registry

Some emergency standards use a policy based routing mechanism where a policy rule has a series of testable conditions. One such condition is "SIPHeaderCondition" which tests a SIP header field in the INVITE or MESSAGE of a call (such as "From", "To", "Contact", etc.). SIPHeaderCondition has an "operator" member has three potential values:¶

"EQ" for an equality match¶
