Question 1/2 - Application of numbering, naming, addressing and identification plans for fixed and mobile telecommunication services
(Continuation of Q.1/2 and Q.6/2 (partially))
Continuation of studies regarding naming, numbering, addressing, and identification resources within the remit of Study Group 2.
The Question will deal with the issues detailed under Tasks below:
Tasks include, but are not limited to:
Maintenance of existing E-series numbering related Recommendations
Rationale: This project reviews and revises, where and when appropriate, the existing ITU-T numbering, naming, and addressing Recommendations of the E-series and F-series, e.g. E.101, E.118, E.129, E.156, E.157,E.164, E.164.1, E.164.2, E.164.3, E.168, E.168.1, E.169, E.169.1, E.169.2, E.169.3, E.190, E.191, E.191.1, E.193, E.195, E.212, E.213, E.214, E.217, E.218, E.370, E.910, E.1100.
This project will ensure that these Recommendations are updated to reflect the current circumstances of the global telecommunications industry and regulatory environment taking into account NGN and IP-based networks. As an example, several recommendations were revised and updated during the last study period. This project also addresses requests for resources described in Recommendations such as E.212, E.164 or E.118 resources not covered in any of the projects below.
UIFN/UIPRN/UISCN registrar coordination
Rationale: The Question maintains the Recommendations regarding the administration of Universal International Freephone Numbers (UIFN), Universal International Premium Rate Numbers, Universal International Shared Cost Numbers and ITU-T IND ATM End System Addresses (ITU-T AESAs)
Under this project, the question will consult on an ongoing basis with the Registrar to resolve issues, relative to the above resources and any new resources created in the future, presented by the industry and the Registrar.
Request for numbering resources for new telecommunications services
Rationale: When new global or regional services are developed and proposed for implementation, they often request/require global numbering resources. This project receives and determines such resource requests.
This question will receive, study, and resolve such anticipated requests. Previous examples of such requests include UPT, UIFS, USCS, GMSS, RMSS, etc.
Global evolution of naming, numbering and addressing requirements for telecommunications services
Rationale: This project will undertake to study the potential evolution of global numbering, naming, addressing and identifier methodologies to accommodate current and future services, technologies, capabilities, and architectures. A global understanding of these future methodologies and their evolution would be of significant value to telecommunications network operators, service providers, vendors, planners, forums, and standards bodies worldwide.
The project would initially develop a uniformly-acceptable definition for and an understanding of numbering, naming, addressing and identifiers. Once the definitions are agreed upon, the project would then study and document the projected evolution of numbering, naming, addressing, and any other potential identifier methodologies and its convergence with IP-based systems/networks including the future of numbering. Additionally the project would study and analyse numbering, naming, addressing and identification plans that already exist and that are already widely deployed and used; identify mechanisms that permit interworking between these different plans; identify gaps in plans or interworking that need to be addressed.
Specifically in relation to the future of numbering it is anticipated that there may be a need to revisit issues of personal and terminal mobility, including the concepts of a single terminal being used by multiple subscribers. Personal mobility might include the idea of a subscriber being able to move between terminals whilst communications are active and in progress and also in the time periods between instances of active communications.
With regard to geographic location it is anticipated that NGN may have additional or different requirements for both terminal and subscriber geographic location compared with existing and legacy systems. This could give rise to the requirement for new numbering and identifier resources or the expanded use of the current E.164 and E.212 resources.
Undertaking studies into the "future of numbering" based upon identity management and other similar requirements.
Naming, numbering, addressing and other identifiers for interworking between E.164 numbering plan-based networks and IP address-based networks
Rationale: Convergence of the existing telecommunication networks, both fixed and wireless, with the IP address-based network requires the continuing development of naming, numbering, addressing and other identifier mechanisms to support this convergence.
The project identifies requirements and develops solutions for the interworking between the E.164 numbering plan-based networks and IP address-based networks. The development of a solution includes, but is not limited to, the identification of the E.164 resource, the determination of how these resources will be used and administered, the determination of the E.164 addressing scheme required to support this type of interconnection, and the determination of which, if any, E.164 resources will be made available to IP address-based networks.
In addition, this project will consider identification of identifiers with respect to the longer term goal of convergence of the naming and addressing schemes used in international telecommunication networks.
The objective is a Recommendation(s), as appropriate, containing the results of the above work.
Implementation and Activation of E.164 Numbering Resources
Rationale: The growth of new and existing telecommunication services, as well as the quantity of network operators and service providers due to the evolution of competition in the telecommunications industry, has resulted in the introduction of numerous new geographic and non-geographic numbering resources domestically and internationally. In order for these resources to be activated effectively, new methods are required to increase awareness and implementation of the resources.
This project will study potential new awareness and implementation methods as appropriate and, as a result of the study, will publish these methods in a new E-series Recommendation.
Rationale: Update the existing Number Portability Supplement to include the necessary technical requirement for the introduction of number portability, including with respect to IP address-based networks.
New applications for E.212 MCC + MNC
Rationale: Over the past few years there has been a growing interest for global resources for machine to machine (M2M) services that are not tied to a particular country but have a global outreach. Such services include (but are not limited) to container tracking, embedded SIMs in various vehicles and machines ("xeroxes", vending machines, etc.). A number of M2M service providers, however, do not rely on global resources in general, and MCC 901, in particular to deploy such services. Additionally, for 3G mobile network the concept of Home NodeB can be used for better coverage in for example home environments. Small access points (femtocells) are used to connect the mobile phones in these areas and the femtocells are then connected to the operator core network using DSL or other forms of transmissions. For this use of femtocells, provided by the mobile operator, we understand that there might be a need for a separate PLMN ID (MCC+MNC) that is different from the PLMN ID of the mobile operators macro cells, i.e. there might be a future need for Administrations/NRA to assign more MNCs to mobile operators that starts to deploy femtocells in their PLMNs access networks. These types of applications will put a demand on E.212 resources and the study will evaluate the applications and provide guidance to Administrations on the use of national or globally assigned E.212 resources and the potential impact on E.164 resources.
Rationale: This project provides terms and definitions for use in the field of identifiers (e.g. names, numbers, addresses and other identifiers (IDs)) for public telecommunication services and networks. Consistent terminology is seen as an important factor in ITU-T Recommendations. For the area covering Identifiers, there are important Recommendations in the E-/F-series, but also in the Q- and X-series. In this project, these terms and definitions have been developed, for the most part, from the practice of the use of IDs in traditional telephone networks such as PSTN, ISDN and PLMN-based networks (e.g. 1G and 2G). These terms will continue to be applicable with their current definitions for other telecommunication networks like NGNs, 3G-based PLMNs and other IP-based networks.
Other projects as they are proposed and approved
Rationale: A significant amount of Q.1 work throughout a study period is the result of new issues presented by Q.1 Collaborators. These issues typically resulted in numerous new projects defined and approved during the previous study periods.
Q.1 will continue to define, study, and resolve new issues through the approval of additional projects.
