30、ibed in ITU-T Recommendation I.210 2. The present document contains the stage 1 specification of SS-CAD. The stage 1 descriptions specify the supplementary services as seen by users of networks. The Call Authorized by Dispatcher service is specific to TETRA. ETSI ETSI EN 300 392-10-6 V1.4.1 (2006-08
31、) 7 1 Scope The present document defines the stage 1 specifications of the Supplementary Service Call Authorized by Dispatcher (SS-CAD) for the Terrestrial Trunked Radio (TETRA) system. Stage 1 is an overall service description from the users point of view but does not deal with the details of the h
32、uman interface itself. The present document specifies the service description of the supplementary service and the procedures to be expected with successful and unsuccessful outcomes. In addition, the present document specifies the interactions with other TETRA supplementary services and interworkin
33、g considerations. Charging principles are outside the scope of the present document. The SS-CAD ensures that predefined TETRA calls do not proceed without first being authorized by a dispatcher. 2 References The following documents contain provisions which, through reference in this text, constitute
34、 provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. Referenced documents

43、1 specification 4.1 Description 4.1.1 General description SS-CAD is defined as the ability of the dispatcher to verify and approve a call request before the call is allowed to proceed. The supplementary service shall also apply to the option whereby the dispatcher authorization of incoming call requ
44、ests to specified TETRA addresses is required before the service can proceed. The specified TETRA addresses may be TETRA users or gateways. The incoming calls may be generated inside or outside of the operators TETRA domain. The service shall enable interception of calls due to the following conditi
45、ons: 1) restricted basic service request; 2) restricted destination or source address; 3) restricted area. 4.1.2 Qualifications on applicability to telecommunication services SS-CAD shall be applicable to all TETRA speech and circuit mode data services. 4.2 Procedures 4.2.1 Provision and withdrawal
46、The SS-CAD supplementary service shall be provided by prior arrangement with the service provider. This service may be withdrawn by the service provider. Conditions for SS-CAD shall be defined and linked with the source, basic service request and destination of the call as shown in table 1. Table 1:
