27、an 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. The present document specifies the service description of the supplementary service and the procedures to be expected with successful and
28、 unsuccessful outcomes. In addition the present document specifies the interactions with other TETRA supplementary services and inter-working considerations. Charging principles are outside the scope of the present document. The AL supplementary service enables the served user to place an affected u
29、sers TETRA Mobile Station (MS) into a special type of individual voice call teleservice whereby the called MS shall transmit without any action from, or indication to, the affected user. 2 References The following documents contain provisions which, through reference in this text, constitute provisi

33、 the supplementary service Switching and Management Infrastructure (SwMI): all of the TETRA equipment for a Voice plus Data (V+D) network except for user terminals NOTE: The SwMI enables user terminals to communicate with each other via the SwMI and multiple SwMIs may be connected together using Int

40、S) into a special type of individual voice call teleservice so that the affected users MS transmits without any action from, or indication to, the affected user. As an option SS-AL may be invoked during group call on a group call participating user. The SS-AL call may include a second listening part
41、y. The second listening party may be either individual user or a group. The present document shall not preclude that during ambience listening the called mobile may make and receive calls as normal. The ambience listening call shall not prevent affected user to send and receive short data messages.
42、If the user attempts to power off the terminal, which is in an SS-AL call, the terminal may continue the SS-AL call whilst appearing to shut down. NOTE: A user can ask for SS-AL to be invoked on himself/herself by sending a pre-defined short data status to another user. 4.1.2 Qualifications on appli
43、cability to telecommunications services Ambience listening shall be a special TETRA speech service. 4.2 Procedures 4.2.1 Provision/Withdrawal This service shall be provided by prior arrangement upon subscription with the service provider. The service provider may provide this service on a selective
44、basis to individual TETRA users whilst barring it from others. The subscription may which affected users the served user is authorized ambience listened to. Instead of subscription or in addition to it a password may be required at invocation of the SS-AL service. Arrangements of provision, subscrip
45、tion and password procedures are outside the scope of the present document. The service provider may withdraw this service at any time. 4.2.2 Normal procedures 4.2.2.1 Management of SS-AL service 4.2.2.1.1 Activation/Deactivation The service provider shall permanently activate this supplementary ser
46、vice as a result of the provision. The service provider deactivates the SS-AL service as a result of withdrawal. ETSI ETSI EN 300 392-10-21 V1.2.1 (2003-09) 104.2.2.1.2 Interrogation The TETRA network response to an interrogation request on an affected user or users shall provide the following infor
47、mation to the authorized user: - SS-AL invoked for TETRA identity and the listening party identity; - SS-AL not invoked for TETRA identity. Support of interrogation is optional. 4.2.2.2 Invocation and operation 4.2.2.2.1 Invocation and operation The served user shall invoke Ambience Listening supple
48、mentary service in conjunction of an individual call set up or optionally using SS-AL specific call maintenance procedures to invoke transmission of a speech item, when the affected user is participating to a group call. To invoke SS-AL call, the served user shall apply basic call set-up for individ
49、ual call to the affected user and indicate a request for SS-AL invocation. When the served user so invokes the SS-AL call, the TETRA network shall return notification of acceptance of the request. When the request is accepted the network shall continue the call set up attempt with the affect users MS. The called affected users MS shall acknowledge the call set up request and the ambience listening call shall be established. Optionally SS-AL service may support invocation of SS-AL speech item during a group call and affected users MS may accept SS-AL speech item wh
