10、17 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The IT Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questi
11、ons 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 their turn, produce Recommen
12、dations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC
13、. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The IT draws attention to the possibility that the practice or implementation of this Recommendat

The 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 appro

21、Recommendation E.215 TELEPHONEASDN NUMBERING PLAN FOR THE MOBILE-SATELLITE SERVICES OF INMARSAT (Melbourne, 1988; revised at Helsinki, 1993 and in 1997) 1 Introduction 1.1 Purpose The purpose of this Recommendation is to specify a telephonenSDN numbering plan for mobile earth stations in systems ope
22、rated by Inmarsat. Such systems may include maritime, land-based and aeronautical satellite systems. In the future, the range of mobile satellite systems may also include satellite systems for other applications. 1.2 Terminology The telex numbering plan for Inmarsat is contained in Recommendation F.
23、125. This Recommendation and Recom- mendation F. 125 are designed to be as similar as possible. This Recommendation defines the following terms. 1.2.1 ship station identity: As defined in the Radio Regulations, Appendix 43. See also Recommendation E.210. 1.2.2 terminal equipment connected to an lnma
24、rsat mobile earth station for access from a public network. Inmarsat mobile international number: The number following the international prefix which identifies 1.2.3 allocated to Inmarsat. Inmarsat mobile number: The part of the Inmarsat mobile international number which follows E.164 codes 1.2.4 s
25、atellite service, ship earth station, etc., see the Radio Regulations. other definitions: For definition of terms such as maritime mobile-satellite service, aeronautical mobile- 1.2.5 identifying: on-board identification digits: These digits are the part of the mobile earth station number used for a
26、 specific terminal equipment on board; a specific mobile earth station. 1.3 Basic considerations The considerations which form the basis of the numbering plan are: 1.3.1 that it shall be possible to identifi an Inmarsat mobile earth station uniquely from the Inmarsat mobile number; 1.3.2 all types o
27、f public networks; that the Inmarsat mobile number should have a format where the same number could be used for access from 1.3.3 few as possible; 1.3.4 that the number of three-digit E.164 codes required for supporting future Inmarsat requirements should be as that different routings could be used
28、for calls to mobile earth stations designed for different Inmarsat systems; 1.3.5 systems; that Administrations and Inmarsat could apply different charging and accounting rates to different Inmarsat 1.3.6 terminal equipment connected to a mobile earth station, e.g. on board a ship; that the numberin
29、g plan should provide capacity for on-board identification or direct access to a specific Recommendation E.215 (0997) 1 STD-ITU-T RECMN E.215-ENGL 1797 48b2591 Ob38705 228 Country code 1.3.7 that the numbering plan should support access to multichannel mobile earth stations; Application 1.3.8 that t
30、he new mobile earth station numbering plan should incorporate numbering plan(s) already in use for the Inmarsat-A system; 1.3.9 that the length of the Inmarsat mobile international number should comply with Recommendation E.164 and will be limited to 12 digits until 1st January 1997 (see also Recomm

33、nternational number The general format of the Inmarsat mobile international number is: where CCC is a three-digit E.164 code allocated to Inmarsat as shown in Table 1 and Tl(T2) X1 . Xk is the Inmarsat mobile number. The number of T digits will vary between one or two, according to the particular In
34、marsat system involved as shown in Table 2. The format of the mobile number is given in clause 4. 3 E.164 codes for Inmarsat applications E. 164 codes for Inmarsat applications are given in Table 1. Single Network Access Code (Notes 1 and 2) Atlantic-East Ocean Region, Inmarsat Pacific Ocean Region,
35、 Inmarsat Indian Ocean Region, Inmarsat Atlantic-West Ocean Region, Inmarsat NOTE 1 - E. 164 code 870 has been allocated to enable the originator of a call to an Inmarsat mobile earth station to dial one E.164 code for worldwide access. NOTE 2 - The code 870 has been allocated by the ITU on the unde
36、rstanding that by 1 July 2015 at the latest, Inmarsat systems and associated mobile earth stations will be accessed from the fixed network using only the single E.164 code 870. When this objective is achieved, the E.164 codes 871-874 will be returned to the ITU. 4 Format of Inmarsat mobile number 4.
37、1 General format The general format of the Inmarsat mobile number is: Tl(T2) xIx2 Xk where a single or double digit T is used for discrimination between different Inmarsat systems. 2 Recommendation E.2 15 (05/97) The formats used for the various Inmarsat systems are defined below. The values of the
38、T digits are summarized in Table 2. The T digits represent a limited resource and a new T digit(s) should therefore only be allocated when necessary for technical or operational reasons. The ITU-T/TSB would be responsible for co-ordinating the allocation of new T digits with the competent Study Grou

The length of the Inmarsat mobile number wi

43、ommendation E.165 and associated Recommendation E.162). Annex C proposes a method by which this expansion can be made in order to allow two-number lengths to coexist on the same T digit. 4.4 Format for Inmarsat-C system 4.4.1 Maritime mobile - Ordinary calls For ordinary calls to ship earth stations
44、 in the 1nmarsat-C system, the format shall be initially: 4 (9 digits) where 4 corresponds to the T digit and where at least the digits MlI2D3x this is reserved for future Inmarsat applications. The length of the Inmarsat mobile number will be 9 digits, making the length of the Inmarsat mobile inter
45、national number equal to 12 digits. 4.4.2 For ordinary calls to land-based mobile earth stations in the Inmarsat-C system, the format shall be initially: Land mobile - Ordinary calls where 4 corresponds to the T digit and the digit 9 signifies a land-based mobile earth station and the digits L213D4

The length of the Inmarsat mobile number will be 9 digits, making the length of the Inmarsat mobile international number equal to 12 digits. 4.4.3 Group calls Group call selection in the Inmarsat-C system is achieve
47、d using two-stage access procedures which do not conform with the scheme outlined in Annex B. 4.4.4 Future extension of the number For maritime satellite applications, the Inmarsat mobile number used in the Inmarsat-C system may be extended to 12 digits as the numbering capacity of the international
48、 network is increased (see Recommendation E. 165 and associated Recommendation E.162) in a way similar to those of the B system (see 4.3.5). Annex C proposes a method by which this expansion can be made in order to allow two-number lengths to coexist on the same T digit. Recommendation E.2 15 (0997)
