7、ITU-T F.19 (10/1996) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and
8、tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce R
9、ecommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Rec
10、ommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the u
11、se of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendatio
12、n, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2002

14、 2 ITU-T F.19 (10/1996) 1 Recommendation F.19 COLLECTION AND DISSEMINATION OF OFFICIAL SERVICE INFORMATION (Approved as ITU-T C.2 in Helsinki, 1993; revised in Geneva, 1996, renumbered as F.19 in 2002) The ITU-T, considering a) Article 1 of the Constitution (Geneva, 1992) and Article 15 of the Conve
15、ntion (Geneva, 1992); b) Article 8 of the International Telecommunication Regulations (Melbourne, 1988); c) Resolution 21 adopted by the World Telecommunication Standardization Conference (Helsinki, 1993) and the results of the ITU-T studies undertaken pursuant to that Resolution; d) Resolutions 39,
16、 65 and 66 adopted by the Plenipotentiary Conference of the International Telecommunication Union (Kyoto, 1994), recognizing a) that the TSBs collection and dissemination of official service information of an administrative, operational, tariff and statistical nature (hereinafter referred to as offi
17、cial service information) assists Administrations and ROAs in their efficient administration and provision respectively of international telecommunication services; b) that the ITU Operational Bulletin has provided an effective method of promulgating much of this type of information; c) that the dec
18、ision for the ITU-T to collect and to disseminate official service information should be taken with a view to cost-effectiveness as regards the burden both: on Administrations and ROAs in providing the information; and on the TSB in the preparation and dissemination of that information; d) that ROAs
19、 also exchange information of an operational nature directly among themselves, and that in some cases (e.g. where many ROAs are affected) some standardization of the content and/or format of the information exchanged may be desirable, recommends that the following general principles should be applie
20、d regarding the collection and dissemination of service information, particularly the official service information disseminated by the TSB. 1 Service information requirements 1.1 Whenever a Study Group identifies a new requirement (or the need for a major change in the existing arrangements) for col
21、lection and dissemination of service information: a) it should consider whether the relevant ROAs (and/or Administrations) should communicate such service information among themselves directly; or b) if ITU involvement is desired, the Director of the TSB shall be consulted concerning the justificati
22、on for that involvement, taking into account the perceived market needs, ITU budget considerations, and any other ITU administrative implications before proceeding. 1.2 In cases a) and b), the requirement should be laid down within ITU-T Recommendations. The relevant Recommendation should specify un
23、ambiguously and at least in general terms the nature of the different types of information required. Where appropriate, it may also specify the format, periodicity, entry into effect, and/or procedures for updating the relevant service information. 1.3 In case a), the information exchanged is not re
24、garded as official service information. Nevertheless, in some cases it may be appropriate to specify that each source ROA (or Administration) should supply a copy of the information or a summary of it to the TSB. 2 ITU-T F.19 (10/1996) 1.4 Each Study Group responsible for the maintenance of such Rec
25、ommendations shall review the relevant provisions at least once towards the end of each period between two WTSCs. 2 Collection of data for official service information 2.1 The Director of the TSB should request Administrations and/or ROAs to supply official service information, or any changes to pre
26、viously supplied information, for dissemination in accordance with the provisions of the relevant Recommendations. The form of the request should be designed to minimize the effort required of the Administrations and/or ROAs in providing the information requested. 2.2 Administrations (and/or ROAs) s
27、hould reply to such requests for information, to the extent practicable, in a timely fashion and in accordance with national arrangements, taking due account of the confidentiality of possibly commercially sensitive information. 2.3 Upon receipt of a request for official service information, Adminis
28、trations may elect (on a case-by-case basis or an until-further-notice basis), in accordance with national practice, to make arrangements to collate replies from their ROAs. Any Administration exercising such election shall notify the Director of the TSB. Absent such election and notification, the T
29、SB should expect individual replies from the ROAs. In processing the individual replies, the TSB shall consider them as emanating from an ROA duly authorized by the relevant Member (or its Administration) to offer the relevant telecommunication service(s) to which the request for information pertain
30、s. 3 TSB administrative support 3.1 The Director of the TSB provides advice and support to the various Study Groups responsible for the Recommendations requiring the collection and dissemination of official service information, in particular as outlined in 1.1, 2.1 and 2.3 above. 3.2 In addition, an
31、d in view of the responsibilities vested in his office, the Director makes suitable arrangements: a) to establish and to keep up to date, for each Study Group, a list of those Recommendations that require the collection and dissemination of official service information; b) to submit such a list to e
32、ach Study Group concerned on request, and in any case at least twelve months prior to a WTSC, for possible revision (amendments, additions and/or deletions) in the light of operational experience; c) to ensure that the method of disseminating official service information reflects technical developme
33、nts in the means of collecting and exchanging such information and that the most appropriate and economic solutions are adopted, while taking due account of the needs of countries where electronic access to ITU databases, for example, is not yet available; d) to establish and to keep up to date on t
34、he basis of the responses returned, a list of the relevant service and/or network providers that have provided the official service information and whether their status is that of an Administration, ROA or other entity.
