CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendati

The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Pl

    5、enary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). Recommendation F.lll was prepared by Study Group I and was approved under the Resolution No. 2 procedure on the 11 of March 1991.

CCITT RECMN*F.LLL 31 m 4862593 0563333 7 m Recommendation F. 11 1 PRINCIPLES OF SERVICE FOR MOBILE SYSTEMS 1 Scope 1.1 This Recommendation defines the principles applicable to international public correspondence service provided by mobile systems connected to

    8、 the international telecommunication (fixed) networks. This Recommendation applies to aeronautical, land and maritime mobile-satellite and terrestrial systems. 2 Introduction 2.1 There is an increased availability of mobile telecommunication systems on an intemational, regional and national basis. I

    9、nternational mobile satellite systems offer telephone, data and telex services to aeronautical, land and maritime mobile users. Regional and national cellular systems, both analogue and digital, are in operation or at an advanced planning stage. Users of these mobile systems expect to be connected t

    10、o the international telecommunications networks and be able to obtain international services available to fixed network customers. In order to ensure that both fixed and mobile user needs are met, principles of service for both satellite and terrestrial mobile systems when interworking with the inte

    11、rnational telecommunication networks are presented in this Recommendation. 3 Services 3.1 telecommunication networks should, as far as practicable, be similar to those offered on fixed networks. The services offered by mobile systems (e.g. voice, data, telex) when interworking with the international

    12、 4 Operation 4.1 When interworking between the mobile system and the fixed network the operational procedures for mobile system users should, wherever possible, be the same as for fixed networks. The same tones, announcements, service codes and signals, etc., used in the fixed network should be reco

    13、gnized and where appropriate returned by the mobile system. 4.2 the country in which it is resident. Any numbering plan for a national mobile system normally is part of the relevant national numbering plan of 4.3 For international mobile systems the numbering plan should either be derived from the n

    14、ational numbering plan of the participating countries or follow the international numbering plan applicable for the services to be provided. 4.4 accounting functions that might be required. There should be mechanisms in place to cater for the needs of any call recording, billing and international 5

    15、Service between mobile systems 5.1 There should be no restrictions to establishing international calls between mobile terminais in different mobile systems via the relevant fixed network(s). For example, a user of a land mobile cellular terminal should be able to make an international telephone call

    16、 to a mobile satellite terminal using the established intemational routing methods and procedures. Recommendation F.lll 1 6 Quality of service 6.1 experienced by the mobile user should be, where practical, similar to that of a user of a fixed network service. The quality of service (e.g. bit error r

    17、ate for data) of a mobile system should be such that the service 7 Service limitations 7.1 It is recognized that because of various reasons that mobile systems may not provide all the same services to their users as provided to users of the fixed telecommunication networks. Any limitation on service

    18、 imposed by the mobile system on its users should, as far as practicable, not adversely affect the quality of service provided to fixed network users when the systems are interconnected. 8 Special mobile services 8.1 It is recognized that mobile systems often provide services other than the conveyan

    19、ce of public correspondence. Mobile services may involve special services, e.g. priority and/or preemption treatment for safety of life messages, navigation, etc. 8.2 Facilities for such special services are not necessarily available within the fixed networks. Where necessary Administrations should make any arrangements for the provision of these services (e.g. dedicated circuits), which is then a national matter outside the scope of CCITT Recommendations. 8.3 CCITT Recommendations cover the effects of such special services on calls to/from the fixed networks. 2 Recommendation F.lll
