1、 ITU-R RECMN*H- SERIES*PT*3 95 4855222 0528022 933 RH!. ITU-R M.1171 169 RECOMMENDATION ITU-R M. 1 17 1 * RADIOTELEPHONY PROCEDURES IN THE MARITIME MOBILE SERVICE ( 1995) The ITU Radiocommunication Assembly, considering that there is a need to describe standard procedures for radiotelephony in the m
2、aritime mobile service, a) recommends that radiotelephony in the maritime mobile service should be performed in accordance with Annex 1. 1 ANNEX 1 Section I. Introduction 5 1. Radiotelephone stations should, as far as possible, be equipped with devices for instantaneous switching from transmission t
3、o reception and vice versa. This equipment is necessary for all stations participating in communication between ships and subscribers of the land telephone system. 5 2. (1) Stations equipped for radiotelephony may transmit and receive radiotelegrams by means of radiotelephony. Coast stations providi
4、ng such service and open for public correspondence shall be indicated in the List of Coast Stations. (2) To facilitate radiocommunications the service abbreviations given in Recommendation ITU-R M. 1 172 may be used. Section II. Calls by Radiotelephony 5 3. The provisions of this Section relating to
5、 the intervals between calls are not applicable to a station operating under conditions involving distress, urgency or safety. 8 4. (1) As a general rule, it rests with the ship station to establish communication with the coast station. For this purpose the ship station may call the coast station on
6、ly when it comes within the service area of the latter, that is to say, that area within which, by using an appropriate frequency, the ship station can be heard by the coast station. (2) However, a coast station having traffic for a ship station may call this station if it has reason to believe that
7、 the ship station is keeping watch and is within the service area of the coast station. * This Recommendation should be brought to the attention of the International Maritime Organization (IMO), and the Telecommunication Standardization Sector (ITLJ-T) Nute by the Secreturiat: The references made to
8、 the Radio Regulations (RR) in this Recommendation refer to the RR as revised by the World Radiocommunication Conference 1995. These elements of the RR will come into force on 1 June 1998. Where applicable, the equivalent references in the current RR are also provided in square brackets. COPYRIGHT I

(1) In addition, each coast station shall, so far as practicable, transmit its calls in the form of “traffic lists con
10、sisting of the call signs or other identification in alphabetical order of all ship stations for which it has traffic on hand. These calls shall be made at specified times fixed by agreement between the administrations concerned and at intervals of not less than two hours and not more than four hour
11、s during the working hours of the coast station. (2) Coast stations shall transmit their traffic lists on their normal working frequencies in the appropriate bands. The transmission shall be preceded by a general call to all stations. (3) The general call to all stations announcing the traffic lists
12、 may be sent on a calling frequency in the following form: - “Hello all ships” or CQ (spoken as CHARLIE QUEBEC) not more than three times; - the words THIS IS (or DE spoken as DELTA ECHO in case of language difficulties); - . . . Radio” not more than three times; - “Listen for my traffic list on . .

14、spoken as DELTA ECHO in case of language difficulties); - “ . . . Radio”, twice; - “Listen for my trafic list on channel . . . ”. In no case may this preamble be repeated. (5) The provisions of 0 5.(3) are obligatory when 2 182 kHz or 156.8 MHz is used. (6) The hours at which coast stations transmit
15、 their traffic lists and the frequencies and classes of emission which they use for this purpose shall be stated in the List of Coast Stations. (7) Ship stations should as far as possible listen to the traffic lists transmitted by coast stations. On hearing their call sign or other identification in
16、 such a list they must reply as soon as they can do so. (8) When the traffk cannot be sent immediately, the coast station shall inform each ship station concerned of the probable time at which working can begin, and also, if necessary, the frequency and class of emission which will be used. 0 6. Whe
17、n a coast station receives calls from several ship stations at practically the same time, it decides the order in which these stations may transmit their traffic. Its decision shall be based on the priority (see RR No. S53.1 No. 44411) of the radiotelegrams or radiotelephone calls that the ship stat
18、ions have on hand and on the need for allowing each calling station to clear the greatest possible number of communications. p 7. cease. (I) When a station called does not reply to a call sent three times at intervals of two minutes, the calling shall (2) However, when a station called does not repl

(3) In areas where reliable VHF communication with a called coast station is practicable, the calling ship station may repeat the call as soon as it is ascertained that trafic has been terminated at the coast station. (4) In the case of a commun
20、ication between a station of the maritime mobile service and an aircraft station, calling may be renewed after an interval of five minutes. (5) Before renewing the call, the calling station shall ascertain that the station called is not in communication with another station. COPYRIGHT International

ITU-R M.1171 171 (6) If there is no reason to believe that harmful interference will be caused to other communications in progress, the provisions of $ 7.(4
22、) above are not applicable. In such cases the call, sent three times at intervals of two minutes, may be repeated after an interval of not less than three minutes. (7) However, before renewing the call, the calling station shall ascertain that further calling is unlikely to cause interference to oth
23、er communications in progress and that the station called is not in communication with another station. (8) Ship stations shall not radiate a carrier wave between calls. $ 8. When the name and address of the administration or private operating agency controlling a ship station are not given in the a
24、ppropriate list of stations or are no longer in agreement with the particulars given therein, it is the duty of the ship station to furnish as a matter of regular procedure, to the coast station to which it transmits traffic, all the necessary information in this respect. $ 9. (1) The coast station
25、may, by means of the abbreviation TR (spoken as TANGO ROMEO), ask the ship station to furnish it with the following information: a) position and, whenever possible, course and speed; b) next port of call. (2) The information referred to in $ 9.(1) above, preceded by the abbreviation TR, should be fu
