ITU-R SM.1413-4 1 RECOMMENDATION ITU-R SM.1413-4 Radiocommunication Data Dictionary for notification and coordination purposes (Question ITU-R 65/1) (1999-2003-2005-2014-2017) Scope The aim of the Radiocommunication Data Dicti
9、onary (RDD) is to improve the exchange of notification and coordination data between administrations and between administrations and the Radiocommunication Bureau (BR) by: providing a single comprehensive reference source; presenting consistent, accurate and unambiguous descriptions for the data wit
10、h, where appropriate, references to other ITU documentation containing additional relevant information; providing administrations with a resource for their internal frequency management processes which could include such items as staff training, exchange of technical data, upgrading of computer-base
11、d systems, and conference and meeting preparation. The ITU Radiocommunication Assembly, considering a) that the notification and coordination procedures cover a wide range of radio systems that have been developed over time; b) that there is a need to develop and adopt more precise criteria for freq
12、uency sharing and coordination of new and existing systems in both space and terrestrial environments; c) that the impact of rapidly changing technology and the introduction of new services will increase the number of data elements to be uniquely identified and will require a data dictionary to be b
13、oth flexible and part of a managed system; d) that administrations need to be able to adequately and correctly identify frequency management information and descriptions for many internal processes including staff training, conference and meeting preparations; e) that the variations in data definiti
14、ons and units across the different services and frequency bands complicate the unique identification of every data element; f) that for electronic data exchange to be successful the data to be exchanged between administrations and the ITU Radiocommunication Bureau must first be agreed and uniquely i
15、dentified; g) that Appendix 4 of the Radio Regulations (RR) defines the data sets to be provided, at different stages or for different categories of services, to the ITU Radiocommunication Bureau by the administrations, but does not define in detail the data elements themselves or their formats; h)
16、that more detailed definitions and formats for data elements are spread over a number of ITU-R texts, including Circular Letters and the Preface to the International Frequency List (IFL), and that it would be advisable to concentrate all of this information into a single text; i) that the introducti
17、on of a data dictionary containing the radiocommunication terms for uniquely defined data elements associated with the notification process would: aid the introduction of Electronic Data Exchange; simplify the translation process for ITU-R texts and other texts into other languages; REC. ITU-R SM.14
18、13-4 2 make it easier for all administrations to understand the definition of terms regardless of the original language used to define them; improve the accuracy of data supplied by administrations; j) that a data dictionary would need to be maintained to allow for changing technology and future exp
19、ansion in the number of data elements listed; k) that the existence of a data dictionary would provide assistance to World Radiocommunication Conferences (WRCs) in updating and improving the RR, in particular Appendix 4, recognizing a) that a data dictionary will require an on-going procedure for ma
20、king improvements and keeping it up-to-date with developments in radiocommunications, recommends 1 that the Radiocommunication Data Dictionary (RDD) contained in Annex 1 should be used as a reference to supplement Appendix 4 of the RR for facilitating the advanced publication, coordination and notif
21、ication processes of frequency assignments with the ITU Radiocommunication Bureau and in the coordination processes between administrations; 2 that Radiocommunication Study Group 1 should ensure that the RDD is maintained on an on-going basis with the help of a Rapporteur group including participati
22、on by the ITU Radiocommunication Bureau. REC. ITU-R SM.1413-4 3 Annex 1 Radiocommunication Data Dictionary Background In developing guidelines for administrations on the electronic exchange of spectrum management information, it was recognized that notification and coordination data were the most co
23、mmon items of information exchanged between administrations, and between administrations and the Radiocommunication Bureau (BR). However, the information required to facilitate this exchange is contained in numerous documents often with inconsistent or inaccurate descriptions. In some documents this
24、 information, or the associated explanation, is so brief that its meaning is ambiguous or misleading. These problems make the notification and coordination of radio systems difficult for both administrations and the BR, introducing unnecessary delays and causing the whole process to take more effort
25、. If the delays in the notification and coordination process result in delays to the introduction of services, this could increase the associated costs for both administrations and radio system operators. Increasing congestion in the radio spectrum and the need for greater sharing will increase the
26、volume of data to be exchanged. If data exchange, in paper form, is to be accomplished efficiently and effectively, it is important that the precise meaning of the data to be exchanged is understood by all parties involved in the process. If this data is to be exchanged electronically, then a precis
27、e understanding becomes essential. To resolve these problems it was proposed that a dictionary of radiocommunication data used in the notification and coordination processes should be developed. Such a document could also be useful to administrations in their own internal frequency management proces
28、ses, particularly where computer-based systems are being implemented which by necessity must cover a multitude of functions such as licensing, engineering tools and applications, staff training, etc. It also has potential for assisting administrations in developing their various inputs to technical
29、meetings and conferences both within the ITU structure and with other external organizations where technical issues may be discussed. The RDD is intended to serve as an authoritative reference for information concerning data used in the notification and coordination processes. It is also expected th
30、at the RDD will replace the data descriptions in the Preface to the IFL. The RDD includes for each data element: an accurate, unambiguous description; data format information; and conditions of use. In addition, tables are provided for each type of radio service that outline the information required
31、 when coordinating or notifying stations in those radio services. It has also become apparent that there is a possible impact on sections of the Radio Regulations, particularly Appendix 4 which provides the current requirement and definitions of data items used for coordination and notification. Whi
32、le many of the ambiguities in RR Appendix 4 have been resolved, the complexity of the systems and their changing requirements can always lead to the need for further clarification of the RR Appendix 4 data requirements and rationalization of redundant data. Administrations are invited to regularly c
33、onsider these possible changes since, if they are to be implemented, they will need to provide suitable proposals to an appropriate WRC. REC.

ITU-R SM.1413-4 6 1.0 Introduction The Radiocommunication Data Dictionary (RDD) describes the information required for the notification of terrestrial and space radiocommunication systems. The RDD also describes the specific
37、conditions under which notifications are required by Appendix 4 of the Radio Regulations (RR), other provisions of the RR and the various Regional Plans. In addition, the RDD contains the information required for the coordination of terrestrial and space services. Further, the RDD provides a common
38、data structure for the exchange of radiocommunication data among different parties, whether electronically or by other means, in accomplishing various spectrum management functions. In fact, the single data format for each data element that the RDD provides is not only a necessity when performing au
39、tomated, electronic retrievals used in calculations, but a very useful tool for exchange of data by any means. The common data structure also promotes common understanding as all parties communicate using the same definitions, formats, etc. for the same piece of information. 1.1 Background The infor
40、mation required for the international filing process is contained in a variety of documents (e.g., Radio Regulations, Regional Plans, Rules of Procedure, BR Circular Letters, ITU-R Recommendations and the Preface to the IFL). In general, this information may be viewed from three distinct perspective
41、s: a) at treaty level in the Radio Regulations and Regional Plans, b) at the notice level in BR Circular Letters, and c) at the notice/BR publication level in the Preface to the IFL. In each case, the information presented is influenced by the purpose of the respective documents: for the Radio Regul
42、ations and Regional Plans, to define concisely an administrations treaty obligations in respect of the regulatory requirements for the international filing process; for the BR Circular Letters, in the context of the regulatory requirements, the related technical and regulatory examinations performed
43、 on notices and the structure of the BRs databases, to present the details required to complete the various notice types; and for the Preface to the IFL, to describe the data recorded in the BRs various publications (e.g., International Frequency Information Circular (BR IFIC) and additionally to as
44、sist an administration in the completion of a notice. The purpose of each document ultimately affects the structure and understanding of the information (although there is a similarity between the views from the perspective of the Preface to the IFL and the BR Circular Letters that provide guidance
45、on completing the notice types). In addition, the information that is presented in many of the documents is usually structured on the requirements of multiple Services and this can make it difficult to identify the precise requirements relating to an individual Service. While the international filin
46、g process information is described from these different perspectives, the information held by administrations and operators in their data systems is based on national requirements (e.g., licensing or engineering requirements) that are usually held at the service (application) or radiocommunication s
47、ystem level. Due to the differences between the data required for the international filing process and the data held by administrations and operators, there can be differences in understanding that make matching the two sets of data problematic. Bridging this gap in understanding is difficult: for t
48、he BR, due to the wide variation in national requirements (also further complicated by variations in computing systems); and, for administrations, due to the highly specialized knowledge requirements associated with the international filing process. This gap in understanding indicates the need for a
49、 new, additional perspective on the information requirements that is based on the viewpoint of the administrations and operators. In reviewing the range of information requirements, variations in the descriptions of individual data items were identified between different types of documents. As a consequence, there could be inconsistencies between descriptions. Hence, it was concluded that a new view of the international filing process information requirements would not only have to consider the context of the regulatory requirements and the structure of the
