25、(03/2012) Introduction The Telecommunication Standardization Bureau (TSB) of the International Telecommunication Union (ITU) has allocated country codes to national administrations that, in turn, have managed the national (significant) number (N(S)N) element as defined in ITU-T E.164. The N(S)N of e
26、very national numbering plan is unique inside each country, and has evolved over a considerable period of time. These N(S)Ns are currently administered in integrated numbering plans, and national numbering plans, to reflect the legal, regulatory and commercial requirements. In a difficult environmen
27、t, the concept that elements of the national numbering plan could be harmonized to some extent by adopting common principles for the design of numbering plans and choosing identical codes for services of social values (SSV), is strongly encouraged. It should be noted that numbering harmonization cou
28、ld also be useful for facilitating the mitigation of the effects of climate change by collecting information and improving planning and response mechanisms. This is of particular relevance in high-risk regions of the world that are challenged by the severe consequences of such natural disasters as s
29、trong hurricanes, rising sea levels, etc. Harmonization of telecommunication facilities to promote international communications is a concept also considered within the purpose of the ITU and exists with the recognition of the sovereign rights of Member States. This supplement provides guidelines to
30、identify and select numbers that might be useful if harmonization of certain categories of services is desired. Rec.

31、monized numbers 1 Scope This supplement provides the basic concepts and advantages of services that are identified and selected for the assignment of national numbers on a globally harmonized basis. Such number assignment for services of social value (SSV) will be implemented to the extent permitted
32、 by current national numbering plans. Technology requirements are considered out of the scope of this supplement. 2 References ITU-T E.101 Recommendation ITU-T E.101 (2009), Definitions of terms used for identifiers (names, numbers, addresses and other identifiers) for public telecommunication servi

39、ally harmonized numbers 6.1 Process for identifying global harmonization of numbers The definition of the SSV should be used as the basis for a circular to be sent to the Members of the ITU, seeking their input on the following questions: a) Does a service of social value, similar to that specified
40、in the ITU, exist? b) Are there plans to deploy such a service of social value? c) What number(s) is/are currently being used to access such services of social value? The responses to the circular letter should be analysed to identify which number, if any, might be used in a further recommendation t
41、o identify a candidate for use as a national globally harmonized number. If such a number exists, then a further circular letter should be initiated to request Member States to advise: a) what, if any, issues exist in utilizing such a number in the future a. by itself b. in parallel with other exist
42、ing national numbers for similar services. b) under what circumstances use of the possible globally harmonized number would be considered. In the selection of the GHNs, consideration should be given to existing regional numbers and also to numbers that are widespread in many countries across the wor
43、ld. 6.2 Process for specifying a globally harmonized number If the results of the process for identifying a possible candidate for a national globally harmonized number (GHN) (see clause 6.1) are positive, then such a number should be specified either in a new Recommendation or in a supplement to IT
44、U-T E.164. NOTE If a Recommendation is to be used, then the text utilized should be in the same form as in ITU-T E.161.1. Rec. ITU-T E.164/Suppl.6 (03/2012) 3 If global harmonization of a number is difficult in a given country due to the existence of an equivalent commonly-used national number, the
45、GHN could be implemented on a secondary basis. However, any national implementation of GHNs is subject to availability and meeting the national regulatory and legal requirements. When considering the establishment of GHNs, it is advisable that the application of international ITU-T E.164 numbers is
46、also placed under review as an alternative option. 7 Further considerations for identifying and specifying a globally harmonized number It is clear that mobility and mobile communications have a significant role in accessing telecommunications and that such access is increased as more and more peopl
47、e are able to travel with their own terminals, carrying the numbering information of their original network. In this context, having different numbers/codes to provide the same service in different countries might be very confusing. In addition, endeavours to harmonize numbers through technical solu
48、tions that allow a national number from Country A to be routed to either the implemented harmonized number deployed in Country B, or Country Bs implementation of the number for a specific service of social value, should only be done in line with national regulatory and legal requirements, based upon
49、 a commercial implementation. Access from fixed telephones to services of social value would benefit more from the selection and deployment of a harmonized number. Unless and until similar technology, potentially on a converged base to that of the mobile scenario, can be utilized in all telecommunication environments, the use of a possible globally harmonized number should be considered, based on the selection and specification criteria identified above.
