scope:
This European Telecommunication Standard (ETS) defines the stage 2 specification of the Supplementary Service Late Entry (SS-LE) for the Trans-European Radio (TERA).
The SS-le allows radio users to be informed of and, if they are concerned, to join an already existing point-to-multipoint speech call.
Man-Machine Interface (MMI) and charging principles are outside the scope of this ETS.
Stage 2 describes the functional capabilities of the supplementary service introduced in stage 1 description. Stage 2 identifies the functional capabilities for the management of the service in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS) and in the Line Station (LS). Stage 2 also describes the information flows between these entities and also the flows sent over the Inter-System Interface (ISI).
NOTE: The stage 2 description is followed by the stage 3 description, which specifies the encoding rules the information flows and process behaviour for the different entities in SwMI, MS and LS of the service.
