19、ked Radio (TETRA). SS-IC enables a served user, while already participating in an active call (original call) to include new participant(s) into a group call together with the participant(s) in the original call. Man-Machine Interface (MMI) and charging principles are outside of the scope of the pre
20、sent document. Supplementary service specifications are produced in three stages according to the method defined in ITU-T Recommendation 1.130 i. The stage 2 description identifies the functional capabilities and the information flows needed to support the supplementary service as specified in its s
21、tage 1 description (see ETS 300 392-10-17 7). 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 TETRA Voice plus Data termin
22、al equipment and networks. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

ETSI 7 ETSI EN 300 392-1 1-17 VI .I .2 (2002-01) 4 Functional model 4.1 Functional model description The functional model shall comprise the following Functional Entities (FES): FE 1 FE2 FE2 1 FE22 FE23 FE25 FE3 FE5 Served user f
36、unctional entity; Generic combination of FE2 1, FE22, FE23 and FE25; Served user SwMI individual call FE; Group controlling SwMI FE; Another party SwMI in the original call; Affected user SwMI FE; Another party in the original call; Affected user FE (included user). The following relationships shall
37、 exist: ra between FE1 and FE21lFE22; rb between FE23lFE25 and FE3; rc between FE25lFE23 and FE5lFE3; rd between FE21lFE22 and FE23lFE25; re between FE21lFE25 and FE25lFE23. Figure 1 shows these FES and relationships. Figure 2 shows simplified FE model and relationships. rc rd ra re NOTE: Functional
38、 entity FE2 is a combination of FE21, FE22 and FE25 Figure 1: Functional model for the basic operational part of SS-IC ETSI 8 ETSI EN 300 392-1 1-17 VI .I .2 (2002-01) rb user A user B user C Figure 2: Functional model for the basic operation in a single SwMI 4.2 Description of functional entities 4
39、.2.1 Served user functional entity, FEI FE1 is the functional entity which serves the served user for the invocation of SS-IC. 4.2.2 Served user SwMI functional entity, FE21 When it receives a SS-IC invocation from FE1, FE21 checks whether SS-IC has been subscribed and, if yes, sets a second call to
40、 the included party FE5 and requests FE22 to include the original call and the second call (into a group call). 4.2.3 Group controlling SwMI functional entity, FE22 When informed by FE21 that SS-IC has been invoked FE22 includes all participants in the original call and the second call into a single
41、 group call. 4.2.4 Other party SwMI functional entity, FE23 FE23 receives from FE22 the information that SS-IC has been operated for the call and passes it to the other party FE3 entity and modifies the call into a group call, when necessary. 4.2.5 Affected user SwMI functional entity, FE25 FE25 may
42、 receive from FE21 information that SS-IC has been invoked (by the served user) for an individual user inclusion for FE5 availability checking. In that case during SS-IC operation FE25 receives from FE22 a call modification into a group call and passes it to the affected user entity FE5. FE25 may al
43、so receive from FE21 information that SS-IC has been invoked for a group inclusion. In both cases the FE25 performs call set-up to FE5 and informs that the call is an include call. After the inclusion FE25 ceases to exist and FE23 is invoked for the call to serve for any new SS-IC functions. 4.2.6 O
44、ther party functional entity, FE3 FE3 is the functional entity which serves the other party in the original call to inform him that new participants are included into the current call. ETSI 9 ETSI EN 300 392-1 1-17 VI .I .2 (2002-01) 4.2.7 Affected user functional entity, FE5 FE5 is the functional e
45、ntity which serves the affected user to inform him that the call contains more participants than the calling user or the group identity implies (as a result of SS-IC operation). Once the SS-IC operation is completed FE5 ceases to exist and the FE3 serves the other party for any new SS-IC actions. 4.
46、3 Relationship of functional model to basic call functional model Although no formal model has been defiied for basic individual call, that model can be readily derived from the PISN model for basic call, in ISO/IEC 11574 9. FE1 shall be collocated with the two-served user CCAs, in the original call
47、 and the second call. FE21 shall be collocated with the CC functional entities in the served user SwMI for the original call and the second call. FE22 shall be collocated with the CC functional entity in the group controlling SwMI for the group call resulting from SS-IC operation. FE23 shall be coll
48、ocated with the CC functional entity in the other party SwMI for the call in which that user participates (the original call). In the specific case where the affected user participates in both the original call and the second call, FE23 shall be collocated with the CC functional entities for each of
49、 these calls. FE3 shall be collocated with the CCA of the other party for the original call in which that user participates. In the specific case where the other party participates in both the original call and the second call, FE3 shall be collocated with the CCAs for each of these calls. FE25 shall be collocated with the CC functional entity in the affected user SwMI for the call in which that user participates (the original call or the second call). In the specific case where the affected user participates in both the original call and the second call, FE25 shall b
