22、ity to have a multi-connection call, .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 one active call and one call on hold, both calls having been answered. In
23、 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 (.e. removed from the multiparty call but remain connected to the served mobile subscriber). The maximum numb
24、er of remote parties is 5. STD.ETSI GSM 02.89-ENGL L99b = 3900855 UL5898q bL3 Page 8 GSM 02.84 Version 5.0.0: November 1996 1.2.1.1 Indication about multiparty status Notification shall be sent towards the served mobile subscriber and all the remote parties in a multiParty call at the invocation of
25、this Supplementary Service. In addition, a notification shall always be sent towards all remote parties (.e. not towards the served mobile subscriber) every time a new party is added to the multiparty call, Notifications shall also be sent to remote parties when they are put on hold and when they ar
26、e 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 time, some networks might not support the sending of the
27、notifications to the remote parties. 1.2.2 Applicability to telecommunication services The applicability of this Supplementary Service is defined in GSM 02.04 (ETS 300 91 8). 1.2.3 Terminology Served Mobile Subscriber During the invocation and active phase, the service is under the control of the se
28、rved mobile subscriber, .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 provisioned for all Basic Services (BS) subs
29、cribed to and to which it is applicable, .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 for service provider reasons. 1.3.5 Activati
30、on 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 be invoked by the served mobile subscriber
31、by use of a control procedure, as defined in GSM 02.30. 1.3.8 Normal operation with successful outcome Only the served mobile subscriber shall be able to add remote parties to the multiparty call. Page 9 GSM 02.84 Version 5.0.0: November 1996 1.3.8.1 Beginning the multiparty call When the served mob
32、ile subscriber invokes multiParty service from the precondition defined in subclause 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 remote parties can all communicate with one another. 1.3.8.2 Managing an ac
33、tive multiParty call During an active multiParty call, the served mobile subscriber shall be able to: Add another remote party, to which a private communication has been established using the same procedures as in subclause 1.3.8.1, if the number of remote parties does not then exceed the maximum nu
34、mber allowed, which results in an active multiParty call. A “MPTY invoke“ notification shall be sent towards all remote parties. A Retrieve notification (according to GSM 02.83) shall be sent towards all previously held remote parties. Put the connection to multiParty call on hold, .e. place her con
35、nection 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, While the multiParty call is on hold the remaining remote parties in the multipart
36、y 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 subscriber or by the remote party, the served mobile subscriber is in control of a
37、held multiParty call. A Hold notification (according to GSM 02.83) shall be sent towards all remote parties. Separate a remote party: Explicitly choose one remote party to have a private communication with. This results in that remote party being removed from the multiParty call which is placed on h
38、old, and the conversation between the served mobile subscriber and the designated remote patty being a normal active call (see note 1). The remaining remote parties may have communication with each other in this state. As a result of this scenario the private communication can be added again to the
39、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 (according to GSM 02.83) shall be sent towards all remote parties, except the designated remo
40、te party to which a private communication was established. 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. Disconne
41、ct 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 sewed mobile subscriber has a private communication with one of the remote parties and this remote party discon
42、nects 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. - - STD-ETSI GSM 02.89-ENGL L77b m 3900855 OL5878b

Process a Cal
44、l Waiting request. Disconnect the held multiparty call. All calls belonging to the multiparty call shall be released. Disconnect a single remote party.

45、l If the served mobile subscriber is connected to a single active call (regardless whether it is a private communication or a new initiated call) and has a MPTY on hold, she is able to: Managing a single call and a MPTY Disconnect the single active call. Disconnect the held MPTY. Disconnect both. Al
46、l calls, even if they are on hold, shall be released. Join the single active call and the held MPTY together. This would result in an active MPTY, except if the number of remote parties exceeds the number allowed. A “MPTY invoke“ notification shall be sent towards all remote parties. A Retrieve noti
47、fication (according to GSM 02.83) shall be sent towards the previously held remote party. Alternate between both calls. Active MPTY and held call If the served mobile subscriber is connected to a active MPTY and has a single call on hold, she is able to: 1) Disconnect the active MPTY 2) 3) Disconnec
48、t the single held call. Disconnect both. All calls, even if they are on hold, shall be released. 4) Join the single held call and the active MPTY together. This would result in an active MPTY, except if the number of remote parties exceeds the number allowed. A “MPTY invoke“ notification shall be se
49、nt towards all remote parties. A Retrieve notification (according to GSM 02.83) shall be sent towards all previously held remote parties. 5) Alternate between both calls.
