22、l.l (2000-1 2) 1 Scope The present document specifies the stage 2 description of the Supplementary Service Area Selection (SS-AS) for the Terrestrial Trunked Radio (TETRA). SS-AS enables a user to select an area where a call will be set up. Man-Machine Interface (MMI) and charging principles are out

23、side of the scope of the present document. Supplementary service specifications are produced in three stages according to the method defined in CCITT Recommendation I. 130 i. The stage 2 description identifies the functional capabilities and the information flows needed to support the supplementary

24、service as specified in its stage 1 description (see ETS 300 392-10-8 SI). The stage 2 description is followed by the stage 3 description, which specifies the protocols at the air interface and at the various Inter-System Interfaces (ISI) to support the service. The present document is applicable to

25、 TETRA Voice plus Data terminal equipment and networks. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present documen t.

33、ified user who is allowed to define areas and/or interrogate the infiastructure about the SS-AS areas defined for an individual subscriber or for a group served user: calling party who invokes the supplementary service when setting up a group call or an individual call served user SwMI: SwMI where t

34、he served user is currently registered. In a call (whether an individual or a group call), the served user SwMI is the originating SwMI In addition, the following terms and definitions shall apply: geographical definition: definition of an SS-AS area given by limits on a map. In practice, due to the

35、 difficulty to describe mathematically any area shape, only circles, areas along a line and rectangular areas are specified in SS-AS protocol (see EN 300 392-12-8 9) important user: in a group call, a user considered by the group controlling SwMI as being important. In the case of SS-AS, this defini

36、tion applies also to the calling user of a group call (i.e. even if the group controlling SwMI does not consider that user as being important) site definition: definition of an SS-AS area given as a list of base stations within one or more SwMIs. Such list may be implicit, e.g. area defined as a who

37、le home SwMI with no visited SwMI (i.e. no participating SwMI in the case of a group call, and no other terminating SwMI than such home SwMI in the case of an individual call) 3.2 Abbreviations 3.2.1 Gen eral abbreviations For the purposes of the present document, the following general abbreviations

41、 SS-AS operating FE; FE20 FE3 Authorized user functional entity. Served user current SwMI FE; Managed served usedgroup home SwMI FE; The following relationships shall exist between these FES: ra between FE1 and FE21; rb between FE21 and FE221; rc between FE221 and FE222; rd between FE222 and FE25; r

42、e between FE1 and FE221; rf between FE1 and FE222; rg between FE3 and FE20. Figure 1 shows these FES and relationships for the basic operational part of SS-AS. Figure 1 : Functional model for the operational part of SS-AS NOTE: No functional entity is shown for the called users because the only SS-A

43、S related action for users participating in the group call is to inform them when they fail to restore their call (after having changed location) because of SS-AS operation (i.e. they have moved outside the selected area and either they are not important users for the call or SS-AS operation has not

44、 been inhibited for such users). Such information being delivered to the user call control entity, the corresponding actions are to be considered as basic call actions and not as SS-AS actions ence the absence of SS-AS functional entity for the called users).

45、0-1 2) Explanation about figure 1 FE25 shall check whether it can establish the call within the selected area requested. It shall be located; in the case of an individual call, in the terminating SwMI; in the case of a group call, in: - the group controlling SwMI (for the group members attached to t

46、he group in that SwMI or because it can determine that some participating SwMIs -where group members are attached- are totally outside the selected area); - the participating SwMIs partly outside the selected area. In the case of a group call, both FE221 and FE221 shall be located in the group contr

47、olling SwMI when the selected area is one defined for the group - i.e. per GTSI. FE221 shall be located in the originating SwMI (assuming that the latter is different from the former), for the determination of the area corresponding to the area number sent by FE1, and FE222, in the group controlling

48、 SwMI for SS-AS operation control, when the selected area is one defined for the calling user - i.e. per ITSI. In the case of an individual call, FE221 shall be located in: either - the originating SwMI (FE221 shall then be Co-located with FE21, in which case the relationship rb will “collapse“); or

49、 the called user home SwMI. - FE222 shall be located in the called user home SwMI. If the -individual- call is then established by rerouteing, the protocol for sending the SS-AS information flow over relationship rc actually relays it through the originating SwMI - but such relaying is a stage 3 description issue and not to be taken into account in the stage 2 description. Figure 2 shows these FES and relationships for the management part of SS-AS.
