24、PP TR 21.905 1. SII2 Service Interaction Indicators Two 1 Multi Party service (MPTY) 1.1 Functions and information flows The following Mobile Additional Function has been identified for the Multi Party service: MAF026 Multi Party service related authorizations examination The ability of a PLMN compo
25、nent to determine the authorizations relating to Multi Party service. See figure 2.1. Location: VLR The SDL diagrams for the Multi Party service are shown in figures 1.2 and 1.3. The procedure Handle_MPTY shows the status of the service as perceived by the served mobile subscriber, as well as the st
26、atus as perceived by any of the other parties. Beside this, the SDL diagrams show the actions to be taken by the network and the information provided by the network to the users. Figure 1.x: the procedure Update_Non_Speech_Calls_Status is defined in 3GPP TS 23.018 4. ETSI ETSI TS 123 084 V13.0.0 (20
27、16-01)63GPP TS 23.084 version 13.0.0 Release 13The information flow for the MPTY service is shown in figure 1.5. In the information flow it is assumed that the served subscriber is a mobile subscriber and that the other parties are all fixed ISDN subscribers. For the purposes of the information flow
28、 diagrams it is assumed that there are only two remote parties. Where there are more than two remote parties, signals to any party connected to the MPTY bridge shall be sent to all other parties connected to the MPTY bridge, except where a single remote party is to be selected for a private communic
29、ation. As a consequence of this assumption, after the MPTY is split (to establish a private communication) it contains only one remote party. However, the end state for disconnection of or by that remaining remote party is shown as A-B ACTIVE / MPTY HELD. This is to indicate that the disconnection b
30、y a single remote party will not necessarily cause the MPTY call to be released. This will happen only when that remote party is the only remaining party in the MPTY call. Party A is the subscriber controlling the MPTY call (served mobile subscriber). Party B is the first remote party called. Party
31、C is the second remote party called. Remote parties are disconnected by the generic disconnect/release procedure. Any scenario requiring disconnection of remote parties shown in the SDL diagrams but not explicitly shown in the flow diagrams shall follow the procedure shown in the flow diagrams for s
32、imilar scenarios. Functions to be performed by the fixed ISDN (for example hold authorizations examination) are not shown in the information flow; only the functions to be performed by the PLMN are shown. It is assumed that the MPTY bridge is located in the MSC. To avoid having two calls on hold at
33、the same time the reception of the retrieve request is supervised by a retriever timer T as defined in 3GPP TS 23.083 3. Note that while the MPTY is on hold, the remote parties can continue to communicate with each other. ETSI ETSI TS 123 084 V13.0.0 (2016-01)73GPP TS 23.084 version 13.0.0 Release 1
