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
42、ity with the acknowledgement or rejection of the requested service. This is sent via visited system SwMI FE2 if the served user is in visited system; given that a second listening party is involved in the AL call, provide the second listening partys application with applicable SS-AL data by sending
43、it to the second listening partys service agent FE6 via visited system SwMI FE2 if the second listening party is located in a different system; if any exception conditions are noticed by SwMI, FE2 shall take appropriate action; optionally clear down the AL call if a new incoming call is received for

The functional entity FE5
45、 should clear down the AL call if the affected user attempts to make a new call, normal call disconnection procedures shall apply to the AL call, as specified in EN 300 392-2 i. When the AL call ends FE5 reverts to normal operation. In one SS-AL invocation there may only be one affected user. 4.2.4
