The general aspects, including definitions and recommended provision, of the description of the Supplementary Services are given in TS 22.004. The gr
25、oup of Supplementary Services MultiParty Supplementary Services consists of one Supplementary Service: - MultiParty service (Clause 1). 0.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are eithe
26、r 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. In the case of a reference to a 3GPP document (including a GSM document), a non
27、-specific reference implicitly refers to the latest version of that document in the same Release as the present document. 1 3GPP TS 21.905: “Vocabulary for 3GPP Specifications“ 2 3GPP TS 22.004: “General on Supplementary Services“. 3 3GPP TS 22.030: “Man-Machine Interface (MMI) of the Mobile Station

29、nition This Supplementary Service provides a mobile subscriber with the ability to have a multi-connection call, i.e. a simultaneous communication with more than one party. 1.2 Description 1.2.1 Description A precondition for the multi-party service is that the served mobile subscriber is in control
30、 of one active call and one call on hold, both calls having been answered. In this situation the served mobile subscriber can request the network to begin the multiParty service. Once a multiParty call is active, remote parties may be added, disconnected or separated (i.e. removed from the multiPart
31、y call but remain connected to the served mobile subscriber). ETSI ETSI TS 122 084 V14.0.0 (2017-03)63GPP TS 22.084 version 14.0.0 Release 14The maximum number of remote parties is 5. 1.2.1.1 Indication about multiParty status Notification shall be sent towards the served mobile subscriber and all t
32、he remote parties in a multiParty call at the invocation of this Supplementary Service. In addition, a notification shall always be sent towards all remote parties (i.e. not towards the served mobile subscriber) every time a new party is added to the multiParty call. Notifications shall also be sent
33、 to remote parties when they are put on hold and when they are retrieved in accordance with normal Call Hold procedures. In the case where a previously private communication is added again to the multiParty call, a notification shall be sent towards all remote parties. NOTE: During an interim period
34、 of time, some networks might not support the sending of the notifications to the remote parties. 1.2.2 Applicability to telecommunication services The applicability of this Supplementary Service is defined in TS 22.004. 1.2.3 Terminology Served Mobile Subscriber During the invocation and active pha
35、se, the service is under the control of the served mobile subscriber, i.e. the one who has subscribed to the service. Remote Party Any participant in the multiParty call who is not the served mobile subscriber. 1.3 Normal procedures with successful outcome 1.3.1 Provision This Supplementary Service
36、is provisioned for all Basic Services (BS) subscribed to and to which it is applicable, i.e. not to any subset of these BS. The provision of the Call Hold Supplementary Service is also required. 1.3.2 Withdrawal Withdrawal of the service is made by the service provider upon request by the subscriber
37、 or for service provider reasons. 1.3.5 Activation The Supplementary Service shall be activated by the service provider as a result of provision. 1.3.6 Deactivation The Supplementary Service shall be deactivated by the service provider as a result of withdrawal. 1.3.7 Invocation Multi-Party service
38、will be invoked by the served mobile subscriber by use of a control procedure, as defined in TS 22.030. ETSI ETSI TS 122 084 V14.0.0 (2017-03)73GPP TS 22.084 version 14.0.0 Release 141.3.8 Normal operation with successful outcome Only the served mobile subscriber shall be able to add remote parties
39、to the multiParty call. 1.3.8.1 Beginning the multiParty call When the served mobile subscriber invokes multiParty service from the precondition defined in Section 1.2.1, the network joins the active call and the call on hold together into a multiParty call in which the served mobile subscriber and
40、the remote parties can all communicate with one another. 1.3.8.2 Managing an active multiParty call During an active multiParty call, the served mobile subscriber shall be able to: (i) Add another remote party, to which a private communication has been established using the same procedures as in Sec
41、tion 1.3.8.1, if the number of remote parties does not then exceed the maximum number allowed, which results in an active multiParty call. A “MPTY invoke“ notification shall be sent towards all remote parties. A Retrieve notification (according to TS 22.083) shall be sent towards all previously held
42、 remote parties. (ii) Put the connection to multiParty call on hold, i.e. place her connection to the multiParty call on hold (and typically later retrieve it). The served mobile subscriber may make an enquiry call (e.g. to a potential new remote party) or process a Call Waiting request from this st
43、ate. While the multiParty call is on hold the remaining remote parties in the multiParty call can have communication with each other. As a result of this scenario, the enquiry call or the accepted waiting call can be added to the multiParty call or released. If the call is released by the served mob
44、ile subscriber or by the remote party, the served mobile subscriber is in control of a held multiParty call. A Hold notification (according to TS 22.083) shall be sent towards all remote parties. (iii) Separate a remote party: Explicitly choose one remote party to have a private communication with.
45、This results in that remote party being removed from the multiParty call which is placed on hold, and the conversation between the served mobile subscriber and the designated remote party being a normal active call (see NOTE 1). The remaining remote parties may have communication with each other in
46、this state. As a result of this scenario the private communication can be added again to the multiParty call or released. If the private call is released by the served mobile subscriber or by the remote party, the served mobile subscriber is in control of a held multiParty call. A Hold notification
47、(according to TS 22.083) shall be sent towards all remote parties, except the designated remote party to which a private communication was established. (iv) Terminate the entire multiParty call. When the served mobile subscriber releases, this is interpreted as a request for termination of the entir
48、e multiParty call even if there are calls on hold. No further notification shall be sent. (v) Disconnect a remote party: Explicitly release the remote parties on a one at a time basis (see NOTE 1). In the case when no remote parties remain, the multiParty call is terminated. NOTE 1: If the served mo
49、bile subscriber has a private communication with one of the remote parties and this remote party disconnects or is disconnected a notification is sent towards the served mobile subscriber that she has a multiParty call on hold. The notification about the held multiparty call towards the served mobile subscriber is given by the MS, not by the network.
