0.2 Abbreviations

Abbreviations used in the present document are listed in GSM 01.04.

0.3 Cross phase compatibility

For the following supplementary services, a number of changes exist between the present document and the protocol version 1 specification:

– Call forwarding unconditional;

– Call forwarding on mobile subscriber busy;

– Call forwarding on no reply;

– Call forwarding on mobile subscriber not reachable.

For these supplementary services, the main body of the present document assumes that all network entities comply with this version of the service. In each case, an additional subclause (subclause x.7) defines the additional requirements for when one or more network entities or the MS complies with the protocol version 1 specifications for the supplementary service procedures.
