Rec. No. : E.201

Title :	Reference  recommendation  for  mobile  services

Study Group : II - Network Operation

Version : New

Date of adoption : 1991

Notes :	


Recommendation E.201 provides a reference point for CCITT 
Recommendations related to mobile services. Its purpose is to identify 
and group together all mobile related CCITT Recommendations, in a clear 
and logical manner for easy reference.

Recommendation E.201 also provides a reference point for CCIR 
Recommendations related to mobile services. Other international 
standards organizations, e.g. International Maritime Organization 
(IMO) and International Civil Aviation Organization (ICAO) also 
publish texts (e.g. ICAO Annex 10 to the convention on International 
Civil Aviation Aeronautical Telecommunications) on mobile services. 
These documents as well as CCIR reports on mobile services are not 
listed in Recommendation E.201.

Recommendation E.201 will be useful as a guide to Administrations or 
other bodies which are new to the mobile arena. It is also recommended 
as a reference document when considering the introduction of new 
mobile systems or services.

Recommendation E.201 will be kept up to date by the CCITT. 
Representatives of the CCIR will inform the CCITT Secretariat of any 
changes or additions to the CCIR documents referenced.

Recommendation E.201 includes references on all mobile services and 
systems for which CCITT and CCIR Recommendations are, or are planned 
to be, available. The CCITT Recommendations are listed by grouping 
mobile systems and services into three categories:

	- Satellite systems and services (maritime, aeronautical and 
	  land); 

	- VHF/UHF systems and services (maritime and aeronautical);

	- Terrestrial public land mobile systems and services 
	  (e.g. cellular).
