ITU-R M.585-7 1 RECOMMENDATION ITU-R M.585-7* Assignment and use of identities in the maritime mobile service (1982-1986-1990-2003-2007-2009-2012-2015) Scope This Recommendation provides guidance to
9、 administrations for the assignment and conservation of identity resources for the maritime mobile service. The limitations which constrain assignments for ships which utilize the satellite services of the global maritime distress and safety system (GMDSS) are described in this Recommendation. Annex
10、 1 describes formats for maritime mobile service identities (MMSI) of ship stations, coast stations, aircraft participating in search and rescue operations and other safety-related communications, automatic identification system (AIS) aids to navigation, and craft associated with a parent ship. Anne
11、x 2 describes formats for identification of other maritime devices, such as handheld VHF transceivers with digital selective calling (DSC) and global navigation satellite system (GNSS), AIS-search and rescue transmitter (AIS-SART), man overboard (MOB) and emergency position indicating radio beacon (
12、EPIRB)-AIS. Annex 3 provides specific guidance to administrations for the assignment, management and conservation of identity resources for the maritime mobile service. This guidance further instructs administrations on methods for the reuse of MMSI assignments, particularly for the reuse of those w

15、ouse Authorities (IALA), International Civil Aviation Organization (ICAO), International Hydrographic Organization (IHO), International Maritime Organization (IMO) and Committee International Radio Maritime (CIRM). 2 Rec. ITU-R M.585-7 considering a) the need for structured identities for safety and
16、 telecommunication purposes in the maritime mobile service; b) that the maritime identifier in the maritime mobile service is based on a 9-digit structure; c) that the MMSI is one type of nine digit identifier; d) that the identities designated for devices for special purposes consist of a second ty
17、pe of 9-digit identifier; e) that the unique identity assigned to stations indicated in Annex 1 to this Recommendation should be the MMSI; f) that the identities used for other maritime devices for special purposes indicated in Annex 2 to this Recommendation are not necessarily unique and are not MM
18、SI assignments; g) the need for all maritime identities to be usable with automated radiocommunication systems; h) that the identities assigned to ship stations, coast stations, aircraft participating in search and rescue operations and other safety-related communications, aids to navigation, craft
19、associated with a parent ship, and used for establishing group calls should be of a similar nature; i) that it is possible to use the MMSI to establish a telephone call to a ship after routing through the public switched networks to an appropriate coast station; j) that the public switched networks
20、in many countries have restrictions on the maximum number of digits that may be dialled or keyed to identify the called ship station and the routing coast station, which would prevent the translation of the complete MMSI directly into a diallable number for the ship that is compliant with Recommenda
21、tion ITU-T E.164; k) that whatever restrictions may be required should, in the interests of the development of automatic shore-to-ship operations, be as few as possible; l) that mobile-satellite systems enable the maritime community to participate in or interwork with international public correspond
22、ence telecommunication systems on a fully automatic basis, utilizing the identities, naming and addressing scheme; m) that the current generation of mobile-satellite systems participating in the GMDSS have signalling and routing characteristics requiring ships using these networks to have an MMSI en
23、ding with three zeroes; n) that the numbering scheme specified for future generations of mobile-satellite systems participating in the GMDSS will be designed to meet the needs of the international public correspondence service and is unlikely to offer the facility to incorporate any part of the MMSI
24、 in a diallable number for a ship, noting that all devices referenced in this Recommendation are considered stations as defined in No. 1.61 of the Radio Regulations, recommends 1 that ships complying with the International Convention for the Safety of Life at Sea, 1974, as amended, and other ships e
25、quipped with automated radiocommunication systems, including AIS, DSC, and/or carrying alerting devices of the GMDSS should be assigned maritime mobile service identities in accordance with the Annex 1 to this Recommendation, as appropriate; Rec. ITU-R M.585-7 3 2 that maritime identities used for o
26、ther maritime devices for special purposes should be assigned as specified in Annex 2; 3 that ship stations, including handheld VHF transceivers with DSC and GNSS, coast stations, and aircraft participating in search and rescue operations using digital selective calling equipment in accordance with
27、Recommendation ITU-R M.493 should use their 9-digit numerical identities transmitted as a 10-digit address/self-identity, normally with a digit 0 added at the end of the identity (see also Recommendation ITU-R M.1080); 4 that ship stations, coast stations, and non-shipborne stations using AIS equipm
28、ent in accordance with Recommendation ITU-R M.1371 should use their 9-digit numerical identities; 5 for the purpose of ensuring compatibility with the GMDSS, the numbers, names and addresses of ship earth stations participating in international telecommunication services should be made readily avail
29、able to all authorized entities by the telecommunication service providers concerned; 6 that the guidance given in Annex 3 to this Recommendation should be consulted for the assignment, management and conservation of identities in the maritime mobile service. Annex 1 Maritime mobile service identiti
30、es Section 1 Assignment of identification to ship station 1 Ships participating in the maritime radio services mentioned in recommends 1 should be assigned a nine digit unique ship station identity in the format M1I2D3X4X5X6X7X8X9 where in the first three digits represent the Maritime Identification
31、 Digits (MID) and X is any figure from 0 to 9. The MID denotes the administration having jurisdiction over the ship station so identified. 2 Restrictions may apply with respect to the maximum number of digits, which can be transmitted on some national telex and/or telephone networks for the purpose
32、of ship station identification. 3 The maximum number of digits that could be transmitted over the national networks of many countries for the purpose of determining ship station identity was six. The digits carried on the network to represent the ship station identity are referred to as the ship sta
33、tion number in this text and in the relevant ITU-R Recommendations. The use of the techniques described below should have made it possible for the coast stations of such countries to engage in the automatic connection of calls to ship stations. To obtain the required nine digit ship station identity
34、 a series of trailing zeroes would have to be added automatically to the ship station number by the coast station in order to complete a shore-originated telephone call, for example, carried over the public switched telephone network: Ship station number Ship station identity 4 Rec. ITU-R M.585-7 M1
35、I2D3X4X5X6 M1I2D3X4X5X6070809 4 In accordance with the above, and the relevant ITU-T Recommendations, a numbering plan was instituted for Inmarsat Standard B, C and M systems, which also required that MMSIs with three trailing zeroes be assigned to ships fitting Standard B, C and M ship earth statio
36、ns, due to limitations in telephone switching networks. Although such precautions are generally no longer required, administrations may continue to assign MMSIs in this manner. 5 The above restrictions do not necessarily apply to Inmarsat Standard C systems, as they are not diallable terminals from
37、the public switched telephone network but are only data terminals. 6 With respect to Inmarsat Standard B and M systems and as long as the above restrictions apply, ships reasonably expected to be affected by the above limitations should only be assigned ship station identities with X7X8X9 000. 7 Gro
38、up ship station call identities for calling simultaneously more than one ship are formed as follows: 01M2I3D4X5X6X7X8X9 where the first figure is zero and X is any figure from 0 to 9. The MID represents only the territory or geographical area of the administration assigning the group ship station ca
39、ll identity and does not therefore prevent group calls to fleets containing more than one ship nationality. 8 With the evolution of global mobile-satellite systems, ships earth stations are able to participate in international public correspondence telecommunication services. Ship earth stations hav
40、ing this functionality may be assigned international telecommunication numbers that have no direct correspondence with the ship station MMSI. Those authorized to assign the numbers, names and addresses associated with such ship earth stations should maintain a record of the cross reference relations
41、hips with the MMSI, for example in an appropriate database. For the purposes of GMDSS the details of these relationships should be made available to authorized entities such as but not limited to the Rescue Coordination Centres (RCC)1. Such availability should be on an automatic basis, 24 hours per
42、day 365 days per year. Section 2 Assignment of identification to coast station 1 Coast stations and other stations on land participating in the maritime radio services mentioned in recommends 3 should be assigned a nine-digit unique coast station identity in the format 0102M3I4D5X6X7X8X9 where the d
43、igits 3, 4 and 5 represent the MID and X is any figure from 0 to 9. The MID reflects the administration having jurisdiction over the coast station or coast earth station. 2 As the number of coast stations decreases in many countries, an administration may wish to assign MMSI of the format above to h
44、arbour radio stations, pilot stations, system identities and other stations participating in the maritime radio services. The stations concerned should be located on land or on an island in order to use the 00MIDXXXX format. 1 IMO Resolution A.1001(25) requires that distress priority communications
45、in these systems should, as far as possible, be routed automatically to an RCC. Rec. ITU-R M.585-7 5 3 The administration may use the sixth digit to further differentiate between certain specific uses of this class of MMSI, as shown in the example applications below: a) 00MID1XXX Coast radio station
46、s b) 00MID2XXX Harbour radio stations c) 00MID3XXX Pilot stations, etc. d) 00MID4XXX AIS repeater stations 4 This format scheme creates blocks of 999 numbers for each category of station, however the method is optional and should be used only as a guidance. Many other possibilities exist if the admi
47、nistration concerned wishes to augment the scheme. 5 Group coast station call identities for calling simultaneously more than one coast station are formed as a subset of coast station identities, as follows: 0102M3I4D5X6X7X8X9 where the first two figures are zeroes and X is any figure from 0 to 9. T
48、he MID represents only the territory or geographical area of the administration assigning the group coast station call identity. The identity may be assigned to stations of one administration which are located in only one geographical region as indicated in the relevant ITU-T Recommendations. 6 The
49、combination 0102M3I4D506070809 should be reserved for a Group Coast Station Identity and should address all 00MIDXXXX stations within the administration. The administration may further augment this use with additional group call identities, i.e., 00MID1111, etc. 7 For the purpose of the GMDSS the details of these MMSI assignments should be made available to authorized entities such as, but not limited to, RCC. Such availability should be on an automatic basis, 24 hours per day 365 days per year. 8 The combination 010293949506070809 is reserved for the all coast stations identity and sh
