ITU-R SM.668-1 Summary Why consider Electronic Data Exchange? In todays rapidly changing radio communications business, it is accepted that the use of compute

24、r based techniques is essential if fast, effective, cost efficient spectrum management is to be achieved, particularly when sharing the spectrum between competing services. The continuing growth of these services has resulted in the need to exchange often complex information for coordination, planni

25、ng and notification purposes. A good example of this is when coordinating satellite based systems, which require large volumes of complex information to be exchanged with many organizations. Processing this information using existing manual methods is time consuming, expensive, repetitive, and ties

26、up valuable human resources. Loss of data integrity during the exchange process is highly likely and therefore alternative methods for exchanging information are needed. Electronic data exchange (EDE) offers such a solution. EDE allows direct transfer of information between systems, a simplistic exa

27、mple is diskette exchange. There are many methods which can be used, some simple, others more complex. The method chosen will depend on the type of data to be exchanged, its quantity, the time taken for the exchange of data to be completed and the costs of the data exchange system. Electronic data e

28、xchange not only has the potential to provide administrations and the Radiocommunication Bureau (BR) with improvements in efficiency, but also to enable new methods of manipulation and analysis of data to be developed. These new methods, like visual data analysis, will permit large complex interfere

29、nce scenarios to be more easily handled. Information on the types of systems, their benefits, risks, impact on the business needs and resources, are discussed in the main body of this Guideline. Detailed information is contained in the Annexes. When these Guidelines were prepared, the ITU-R was cons

30、idering and approving the simplification of the Radio Regulations (RR). Because of the existence of both the RR and the simplified RR and the gradual transition between these, the numbering of Articles and Appendices referenced in these Guidelines may change. 1 Introduction in response to Resolution

31、 ITU-R IO and by Radiocommunication Study Group 1 Decision ITU-R YI, Task Group 1/4 was established to develop guidance and provide a source for reference on exchange of information through electronic means to share spectrum management information. This Recommendation provides guidance by outlining

32、the issues requiring consideration by senior managers in organizations who wish to implement or improve electronic data exchange(EDE). It considers among other things the hardware, software, data storage media, data file format and dictionary, security, procedures, communications networks, and the s

33、taff necessary to accomplish this task. The term “spectrum management information” includes, but is not limited to, that information which is needed to carry out the following functions: - portraying frequency band allocations; - monitoring spectrum activity; - - specifying equipmenthystem character

34、istics; - using and transferring analytical models; - accessing regulatory documents. coordinating and/or notifying frequency assignments or orbital positions; The process of exchanging information via electronic or computer related means and transforming that information into a suitable form for au

35、tomatic processing is commonly referred to as EDE. Further, it is implied that the exchanged data will convey information that must be understood by the receiving party if it is to be usable. For successful information exchange, both the sender and receiver must adhere to agreed standards for the co

36、nversion and transmission or transportation of the data. These standards may be human or computer-related, The formei may be understood as a common cultural or technical background and is rarely explicitly formulated. The latter is standardized as a set of accepted formats. EDE may be facilitated in

37、 a number of ways; from the use of physical media such as diskettes, magnetic tape, CD-ROM, to the use of sophisticated electronic file transfer protocols that permits transmitting information via wirelines, fibre optic STD-ITU-R RECMN SM-bbA-L-ENGL 1997 M Li855212 0530117 027 Rec. ITU-R SM.668-1 5

38、cables, or radio wave transmission media. The cost of implementation and the benefits available to administrations will depend on their existing computer facilities, their requirements, and their desired solution. In employing an electronic system to exchange spectrum management information, a degre

39、e of efficiency and effectiveness is expected to be gained. Search and retrieval of documents or technical data are vastly improved. Response times associated with evaluating frequency coordination proposals are reduced or minimized. The time associated with the capture and submission of notificatio

40、n data to the BR is also substantially reduced. These benefits permit improvements in efficiency and may result in savings in staff time. EDE provides the International Telecommunication Union (ITU) with the same benefits as administrations but on a larger scale. To aid the exchange of data electron

41、ically the ITU has therefore established a network facility called TIES (Telecom Information Exchanges Services) that provides diverse telecommunication services to its Members. Within this network the ITU has developed an electronic document data base (ITUDOC), forming an integral part of the ITUs

42、TIES computer-based electronic information services. Further information can be found in Case Study 1 of 6 of Appendix 1. The main text of these Guidelines is intended to provide an overview of each subject or issue with the detailed discussion and analyses being found in supporting Annexes. The Rec

43、ommendation also provides a number of case studies and a glossary of terms. 2 Data and Data Issues 2.1 Introduction Exchanging spectrum management information by electronic means requires a number of data related issues to be addressed in order for the process to be effective. Data can be held in ma

44、ny different forms and the main factors affecting the exchange will vary with each of these forms. For EDE to operate easily and efficiently it is necessary to have compatible standards for representing the data as well as standards for its transfer. However, for information to be exchanged it is al

45、so necessary to understand the exact meaning of the data, as well as having an appreciation of the legal, financial and security issues. These issues should then be addressed and agreed solutions incorporated in a set of standards. 2.2 Standards compliance Individual countries already use many data

46、standards, although they are not necessarily all recognised as such. For example, in the world of radiocommunications it is necessary for all to have a common understanding - “radio” (as part of the electromagnetic spectrum) needs agreed standards for terms, definitions and the way it is quantified

47、and measured. Otherwise, it would not be possible to plan frequency assignments, negotiate and publish performance specifications or issue licences for radiocommunication services. Administrations could not perform the spectrum management function without standards for its operation, such as those i

48、n the internationally agreed rules set down in the RR. EDE will introduce widespread data sharing and for EDE to operate efficiently and effectively it is necessary to extend the range and scope of standardisation. Identification of existing standards and the development of new international standar

49、ds to cover the type of data, its format and the electronic data exchange process will help administrations to exchange data more easily (see also Annex i). 2.3 Critical role of data dictionaries The single most important issue regarding the electronic exchange of data is that all parties involved in the exchange have a common understanding of the meaning of the data. This means they must understand what information is being communicated. To help ensure this understanding, the meaning of the data and how it will be physically represented when exchanged is reco
