Distributing, Exposing, & Registering telephone Numbers (modern)

Would appreciate people¹s thoughts on whether any charter edits may be
warranted in response to these comments, and/or whether a separate response
may be useful for addressing some of the questions below.

> significant numbering resource with direct implications on national
> sovereignty. ITU Plenipotentiary Conference Resolution 133 (Rev. BUSAN, 2014)
> recognized "the existing role and sovereignty of ITU Member States with
> respect to allocation and management of their country code numbering resources
> as enshrined in Recommendation ITU-T E.164", and further instructed the ITU
> Secretary-General and the Directors of three Bureaux (Telecommunication
> Standardization, Development, and Radiocommunication) to "take any necessary
> action to ensure the sovereignty of ITU Member States with regard to
> Recommendation ITU-T E.164 numbering plans whatever the application in which
> they are used".
> 5. Relationship with .Tel
> DNS-based use of international numbering resources has been discussed in ITU-T
> Study Group 2 (SG2) since its meeting of 17-26 September 2013. TSB Director
> has also exchanged letters with ICANN on issues related to registering digit
> strings in the .TEL domain. A representative from ICANN participated in the
> ITU-T SG2 meeting (28 May - June 2014) and provided some background on the
> TELNIC application. A correspondence group under ITU-T SG2 was also set up in
> this regard. We would like to know how the work of this new WG would relate to

> DNS-based use of telephone numbers.
> 6. Relationship with related existing or concluded WGs

> 7. The name of this new WG
> The name of this new WG is "Managing, Ordering, Distributing, Exposing, &

> The MODERN working group will define a set of Internet-based mechanisms for
> the purposes of managing and resolving telephone numbers (TNs) in an IP
> environment. Devices, applications, and network tools increasingly need to
> manage TNs, including requesting and acquiring TN delegations from

> acquisition, and management of TNs simpler for all entities involved.
> 
> The working group will define an information management framework for the
> roles and functions involved in associating information with one or more TNs
> in an IP environment.  The working group will also identify protocol
> mechanisms to support the interactions between the functions defined by the
> framework. This includes either recommending or defining protocol mechanisms
> for acquiring, associating and resolving TNs, with a preference for use of
> existing protocol mechanisms. TNs may either be managed in a hierarchical
> tree, or in a distributed registry. The protocol mechanism for acquiring TNs
> will provide an enrollment process for the entities that use and manage TNs.
> 
> The protocol mechanism for resolving TNs will allow entities such as service
> providers, devices, and applications to access data related to TNs.
> Maintaining reliability, real-time application performance, and security and
> privacy for both the data and the protocol interactions are primary
> considerations. The working group will take into consideration existing IETF
> work including STIR, ENUM, SPEERMINT, DRINKS and SCIM.
> 
> The work of this group will focus on TNs, as defined in RFC3966, and blocks of
> TNs, that are used to initiate communication with another user of a service.
> There is an expectation that aspects of the architecture and protocols defined
> by the working group will be reusable for other user-focused identifiers. Any
> such extensions or reuse of MODERN mechanisms are out of scope for the MODERN
> working group. Solutions and mechanisms created by the working group will be
> flexible enough to accommodate different policies for TN assignment and
> management, for example those established by different regulatory agencies.

> The working group will deliver the following:
> 
> - An architecture overview, including high level requirements and

> - A description of the enrollment processes for existing and new TNs including

> 
> - A description of protocol mechanisms for accessing contact information
