[Modern] Fwd: [new-work] WG Review: Managing, Ordering, Distributing, Exposing, & Registering telephone Numbers (modern)

[Alissa Cooper <[e-mail]>]

Would appreciate people’s 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.

> 1.	Potential impacts on Recommendation ITU-T E.164 and E.164.1 
> It is stated at the beginning of the Charter that 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. And it is mentioned that TNs are defined in RFC 3966 "The tel URI for Telephone Numbers". Does that mean the mechanism being referred to here only deals with Tel URI? Would there be any impact on Recommendation ITU-E E.164 and E.164.1 which are core recommendations on Telephone Numbers?
> 2.	Entities participating in the defined mechanisms
> The Charter states that the protocol mechanism for resolving TNs will allow entities such as service providers, devices, and applications to access data related to TNs. But it is not clear what kind of entities can participate in the mechanisms defined by this MODERN working group. Would it be restricted to the entities who have been assigned a TN or a block of TNS?
> 3.	Status of Telephone numbers in the defined mechanisms
> Several operations related to TNs are mentioned in the Charter, including requesting, acquiring, resolving and associating. It is also stated that the protocol mechanism for acquiring TNs will provide an enrollment process for the entities that use and manage TNs. Does that mean Telephone numbers with various status, such as assigned, spare and reclaimed numbers will all be managed in the mechanisms defined by the MODERN working group?
> 4.	Regulatory issues
> The Charter states that 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. We would like to bring your attention to the fact that the E.164 international public telecommunication numbering plan is a politically 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 issues related to registering digit strings in the .TEL domain and other DNS-based use of telephone numbers.
> 6.	Relationship with related existing or concluded WGs
> It is stated in the Charter that the working group will take into consideration existing IETF work including STIR, ENUM, SPEERMINT, DRINKS and SCIM. Detailed description of the relationship between this new WG and the above mentioned other existing or concluded WGs would be appreciated.
> 7.	The name of this new WG
> The name of this new WG is "Managing, Ordering, Distributing, Exposing, & Registering telephone Numbers (modern)". But in the Charter, ordering, exposing and registering TNs are not mentioned, which seems to be a little bit inconsistent.

> A new IETF working group has been proposed in the Applications and Real-Time Area. The IESG has not made any determination yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg at ietf.org) by 2015-06-22.

> Charter:
> 
> 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 authorities. The output of the working group should make distribution, 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 security/privacy considerations
> 
> - A description of the enrollment processes for existing and new TNs including any modifications to metadata related to those TNs
> 
> - A description of protocol mechanisms for accessing contact information associated with enrollments
> 
> - A description of mechanisms for resolving information related to TNs
