20、084 version 14.0.0 Release 140 Scope The present document gives the stage 2 description of the multi party supplementary services. Only one multi party supplementary service has been defined, this is the Multi Party (MPTY) service, and is described in clause 1. 0.1 References The following documents

21、 contain provisions which, through reference in this text, constitute provisions 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

22、 non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TR 21.905: “3G Vocabulary“. 2 3GPP TS 2

24、e listed in 3GPP 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 o

25、f a PLMN component 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

26、well as the status 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. The information fl

27、ow for the MPTY service is shown in figure 1.5. ETSI ETSI TS 123 084 V14.0.0 (2017-04)63GPP TS 23.084 version 14.0.0 Release 14In 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 in

28、formation flow 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 pr

29、ivate communication. 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 d

30、isconnection by 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

31、called. Party 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

32、diagrams for similar 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 cal

33、ls on hold at 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 V14.0.0 (2017-04)73GPP TS 23.084 version 14
