Radio Equipment and Systems (RES); Trans-European Trunked Radio (TETRA); Voice Plus Data (V + D) Part 10: Supplementary Services Stage 1 Part 10-15: Transfer of Control
This European Telecommunication Standard (ETS) defines the stage 1 specifications of the Supplementary Service Transfer of Control (SS-TC) for the Trans-European Trunked RAdio (TETRA). Stage 1 is an overall service description from the users point of view but does not deal with the details of the human interface itself. This ETS specifies the service description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes. In addition this ETS specifies the interactions with other TETRA supplementary services and inter-working considerations. Charging principles are outside the scope of this ETS. The SS-TC enables the served user during the ongoing multipoint call to transfer the ownership of the multipoint call to another TETRA user within the ongoing multipoint call. This service is not applicable to broadcast calls.
