26、7 ETSI EN 300 392-1 1-21 VI .I .I (2003-04) 1 Scope The present document defines the stage 2 specification of the Supplementary Service Ambience Listening (SS-AL) for the Terrestrial Trunked Radio (TETRA). Stage 2 identifies the functional entities involved in the supplementary service and the infor

27、mation flows between them. Aspects relating to all supplementary services are detailed in EN 300 392-9 2. NOTE: The stage 2 description is followed by the stage 3 description, which specifies the encoding rules for the information flows and process behaviour for the different entities in the SwMI an

28、d in the MS. Charging principles and Man-Machine Interface (MMI) are outside the scope of the present document. The SS-AL enables a 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 affect

29、ed user. The ambience listening call may include a second listening party. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

34、affected user: user whom the served user is listening to served user: user who invokes this supplementary service and listens to the affected user ETSI 8 ETSI EN 300 392-1 1-21 VI .I .I (2003-04) second listening party: TETRA individual or group which additionally listens the AL call 3.2 Abbreviatio

36、n SS is only used when referring to a specific supplementary service. 4 4.1 Functional model Functional model description The functional model shall comprise the following Functional Entities (FES): - FE 1 served users service agent; - FE2 ambience listening control entity; - FE5 affected users serv

37、ice agent; - FE6 second listening partys service agent. The following relationships shall exist between these FES: - ra between FE1 and FE2; - rb between FE2 and FE5; - rc between FE2s in different SwMIs; - rd between FE2 and FE1 in a visited SwMI; - re between FE2 in visited SwMI and FE5 in visited

38、 SwMI; - rf between FE6 and FE2; - rg between FE6 in visited SwMI and FE2 in a visited SwMI. Figure 1 shows these FES and their relationships.

41、 for the data received for interrogation and invocation; provide the affected users application with applicable SS-AL data by sending it to the affected users service agent FE5 via visited system FE2 if the affected user is located in a different system; provide the served users agent functional ent
