INTERNATIONAL  TELECOMMUNICATION  UNION

		     ITU-T RECOMMENDATION SUMMARY


Rec. No. : F.111

Title :	Principles of service for mobile systems

Study Group : I - Services

Version : New

Date of adoption : 1991

Notes :	


There is an increased availability of mobile telecommunication systems 
on an international, regional and national basis. International 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 to 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 international telecommunication 
networks are presented in Recommendation F.111.
