29、io (TETRA) as provided by European operators. Stage 2 identifies the functional entities involved in the supplementary service and the information flows between them. Stage 2 is part of three stage definition where stage 1 (EN 300 392-10-6 1) specifies the service description and the procedures of t
30、he supplementary service and stage 3 specifies the service primitives, PDUs and protocols for functional entities. NOTE: The stage 2 description is followed by the stage 3 description EN 300 392-12-6 2, which specifies the encoding rules for the information flows and process behaviour for the differ
31、ent entities in the SwMI, in the MS and in the LS. Aspects relating to all supplementary services are detailed in EN 300 392-9 7. Man-Machine Interface (MMI) and charging principles are outside the scope of the present document. The SS-CAD ensures that predefined TETRA calls do not proceed without f
32、irst being authorized by a dispatcher. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

39、 whom the request for authorization is directed restricted user: user whose calls are forced to be authorized by a dispatcher before the call can proceed NOTE: The restricted user can be either the calling user A or the called user B or both. 3.2 Abbreviations For the purposes of the present documen
40、t, the following abbreviations apply: CAD Call Authorized by Dispatcher CCA Call Control Agent FE Functional Entity ITSI Individual TETRA Subscriber Identity M Mandatory MMI Man Machine Interface O Optional PDU Protocol Data Unit SS Supplementary Service NOTE: The abbreviation SS is only used when r
41、eferring to a specific supplementary service. SwMI Switching and Management Infrastructure 4 Functional model 4.1 Functional model description The functional model for SS-CAD shall, for each normal call set-up, consider the SS-CAD conditions defined in the subscriber data for both user A and user B
42、respectively. Each of these users can have the SS-CAD authorization restriction which requires the dispatcher authorization at call set-up. The calling user A shall be informed when SS-CAD is invoked. There shall be no SS-CAD related indication to the called user. Different dispatchers can be reques
43、ted to authorize the call if SS-CAD is activated for either user A or user B. The following rules shall apply: - if user A and user B are present in the same SwMI and both have SS-CAD invoked towards the same dispatcher, only one authorization shall be requested; - if user A and user B are present i
44、n the same SwMI and both have SS-CAD invoked towards different dispatchers, then it is outside the scope of the present document if more than one dispatcher authorizes the call; - if user A and user B are in different SwMIs, both SwMIs shall analyse if SS-CAD may be invoked. If invoked for both for
45、both users, both the user A and the user B dispatcher shall be requested to authorize the call in sequence; - if user A migrates to another SwMI outside its own home SwMI, the SS-CAD subscriber data shall follow it to the visited SwMI if SS-CAD shall be invoked there. It is optional for the visited
46、SwMI to support invocation of SS-CAD; ETSI ETSI EN 300 392-11-6 V1.2.1 (2004-01) 9 - if user B migrates to another SwMI outside its own home SwMI, SS-CAD against incoming calls is normally operated in the home SwMI, but the SS-CAD subscriber data shall follow user B to the visited SwMI if SS-CAD sha
47、ll be invoked against incoming calls originating from that visited SwMI (intra-SwMI calls). It is optional for the visited SwMI to support invocation of SS-CAD; - if user B has migrated to another SwMI outside its own home SwMI and that SwMI coincides with the originating SwMI and the originating Sw
48、MI has first routed a call to user B to user B home SwMI (instead of applying an intra-SwMI call), then that SwMI should not operate SS-CAD against that incoming call to user B as the call at that moment is already authorized in the home SwMI of user B. If a subscriber is migrating, the authorizatio
49、n shall, by default, be carried out by the subscribers home dispatcher. Upon agreement between the network operators, the SS-CAD authorization migrated user A and/or user B may be carried out by the dispatcher of the visited SwMI. Additional CAD restrictions can then be applied by the visiting SwMI to a migrating subscriber. The functional model for SS-CAD shall comprise the following Functional Entities (FEs): FE1 calling user As agent; FE2 CAD control entity in the SwMI where SS-CAD is invoked and a generic transport function, see EN 300 3
