31、 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 of on
32、e 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 multiParty call
33、 but remain connected to the served mobile subscriber). The maximum number of remote parties is 5. ETSI ETSI TS 122 084 V15.0.0 (2018-07)63GPP TS 22.084 version 15.0.0 Release 151.2.1.1 Indication about multiParty status Notification shall be sent towards the served mobile subscriber and all the rem
34、ote 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 to re
35、mote 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 of ti
36、me, 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 phase, th
37、e 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 is pro
38、visioned 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 or fo
39、r 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 will b
40、e invoked by the served mobile subscriber by use of a control procedure, as defined in TS 22.030. 1.3.8 Normal operation with successful outcome Only the served mobile subscriber shall be able to add remote parties to the multiParty call. ETSI ETSI TS 122 084 V15.0.0 (2018-07)73GPP TS 22.084 version
41、 15.0.0 Release 151.3.8.1 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 the re
42、mote 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 Section 1
43、.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 remot
44、e 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 state. W
45、hile 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 mobile su
46、bscriber 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. This r
47、esults 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 this s
48、tate. 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 (accor
49、ding 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 entire 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 terminate
