Foreword This Technical Specification (TS) has been produced by ETSI Project Terrestrial Trunk
18、ed Radio (TETRA). The present document is a multi-part standard and will consist of the following parts: Part 1: Part 2: Part 3: Part 4: Part 5: Part 6: Part 7: Part 9: Part 10: Part 11: Part 12: Part 13: “General network design“; “Air Interface (AI)“; “Interworking at the Inter-System Interface (IS

ETSI 6 ETSI TS 1 O0 392-1 1-8 V1.l.l (2000-09) 1 Scope The present document specifies the stage 2 description of the Supplementary Service Area Selection (SS-AS) for the Terrestrial Trunked Radio (TETRA
21、). SS-AS enables a user to select an area where a call will be set up. Man-Machine Interface (MMI) and charging principles are outside of the scope of the present document. Supplementary service specifications are produced in three stages according to the method defined in CCITT Recommendation 1.130
22、 i. The stage 2 description identifies the functional capabilities and the information flows needed to support the supplementary 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
23、 the air interface and at the various Inter-System Interfaces (ISI) to support the service. The present document is applicable to TETRA Voice plus Data terminal equipment and networks. 2 References The following documents contain provisions which, through reference in this text, constitute provision
24、s of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. il CCITT Recommendation I. 130 (

31、esent document, the terms and definitions of EN 300 392-9 7 apply with the following modifications: authorized user: identified user who is allowed to define areas andor interrogate the infrastructure about the SS-AS areas defined for an individual subscriber or for a group served user: calling part
32、y who invokes the supplementary service when setting up a group call or an individual call served user SwMI: SwMI where the 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 defini
33、tions shall apply: geographical definition: definition of an SS-AS area given by limits on a map. In practice, due to the 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 use
34、r: in a group call, a user considered by the group controlling SwMI as being important. In the case of SS-AS, this definition applies also to the calling user of a group call (Le. even if the group controlling SwMI does not consider that user as being important) site definition: definition of an SS-
35、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 whole home SwMI with no visited SwMI (Le. 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 A

SwMI Switching and Management Infrastructure ETSI 8 ETSI TS 1 O0 392-1 1-8 V1.l.l (2000-09) 4 Functional model 4.1 Functional model description The functional model shall comprise the following Functional Entities (
39、FES): FE 1 FE2 1 FE22 1 FE222 SS-AS operation controlling FE; FE25 SS-AS operating FE; FE20 FE3 Authorized user functional entity. Served user functional entity; Served user current SwMI FE; Area number mapping FE; Managed served user/group home S wMI FE; The following relationships shall exist betw
40、een these FES: ra between FE1 and FE21; rb between FE21 and FE221; rc between FE221 and FE222; rd between FE222 and FE25; re 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 : Functi
41、onal model for the operational part of SS-AS NOTE: No functional entity is shown for the called users because the only SS-AS 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 (Le.
42、 they have moved outside the selected area and either they are not important users for the call or SS-AS operation has not 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
43、 SS-AS actions (hence the absence of SS-AS functional entity for the called users). ETSI 9 ETSI TS 1 O0 392-1 1-8 V1.l.l (2000-09) 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,
44、 in the terminating SwMI; in the case of a group call, in: - the group controlling SwMI (for the group members attached to the 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 S
45、wMIs partly outside the selected area. In the case of a group call, both FE221 and FE221 shall be located in the group controlling 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
46、former), for the determination of the area corresponding to the area number sent by FE1, and FE222, in the group controlling 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: eit
47、her - the originating SwMI (FE221 shall then be Co-located with FE21, in which case the relationship rb will “collapse“); or 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-A
48、S 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. NOTE 1 : All requests i
49、ssued by the authorized user for an SS-AS managed served user or group are to be addressed to the home SwMI of this managed served user or group. This holds even if the calling user is given a partial authorized user capability to define selectable areas against his ITSI, or place interrogation about such definition. NOTE 2: The relationship between FE20 and FE21 is an ANF-ISIMM relationship, across which flows the SS-AS profile exchange. NOTE 3: The relationship ra is shown on the figure in case the definition is assigned (.e. downloaded) to the served user. Figure 2: F
