34、04)71 Scope The present document defines the stage 3 specification of the Supplementary Service Ambience Listening (SS-AL) for the Terrestrial Trunked Radio (TETRA). Stage 3 defines the signalling system protocols and switching functions needed to implement the service described in stage 1 and stage
35、 2. Charging principles and Man-Machine Interface (MMI) are outside the scope of the present document. The SS-AL enables the served user to place a TETRA Mobile Station (MS) into a special type of voice call whereby the called MS transmits without any action from, or indication to, the affected user
36、. The SS-AL call can include a second listening party. The affected user can ask other user to set an SS-AL call on him. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
