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.

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

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
