Page IV GSM 04.84 version 4.3.0 1 Multi Party service (MPTY) 3404583 Ol10.5407 077 1.1 Beginning the multi party service The served mobile subscriber A may initiate an active multi party call from an active call C and a
30、 held call B. The mobile station invokes the service by sending a FACILITY message to the network containing the BuildMPTY request. This BuildMPTY request indicates to the network that the mobile subscriber wishes all his calls to be connected together in a multi party call. The network will normall
31、y accept the request and connect the mobile subscriber with the other existing connections (active call C and held call B). If the request is not accepted, the network will indicate the error to the served mobile, see figure 1.1. The network confirms with the same transaction identifier. Error value
32、s are specified in TS GSM 04.80. During the BuildMPTY operation the MS shall run a timer T(Bui1dMPTY). This timer is started when the operation is sent, and stopped when a response is received from the network. If this timer expires the MS shall assume that the operation has failed, locally release
33、the invokelD, and may re- attempt the operation or inform the user of the failure.

36、chieved by the same procedure as in section 1.2.1.3. 1.3.1.5 Explicitly disconnect a remote party This is achieved by the same procedure as in section 1.2.1 -4. Pabe I7 GSM 04.84 version 4.3.0 rn 3404583 0105411 5TT rn 1.3.2 Remote parties During a held multi party call any remote party is able to p
37、erform the same operations as described for an active multi party call in section 1.2.2. 1.4 Managing a single call and a multi party call 1.4.1 Served mobile subscriber If the served mobile subscriber is connected to a multi party call (active or on hold) and another single call (active or on hold)
38、, he can request the network to: 1.4.1.1 Disconnect the single call This is achieved by using the call clearing procedure as described in TS GSM 04.08 with the transaction identifier corresponding to the single call. 1.4.1.2 Disconnect the MPTY This is achieved by the same procedure as disconnecting
39、 a held/active MPTY without another call, see section 1.2.1 and 1.3.1. 1.4.1.3 Disconnect all calls This is achieved by using the procedures in sections 1.4.1 .I and 1.4.1.2. 1.4.1.4 Add the single call to the MPTY The served mobile subscriber may request the connection of all his calls, held and ac
40、tive, into an active multi party call at any time by sending a FACILITY message with the transaction identifier corresponding to any remote party and containing the BuildMPTY invoke component, see section 1 .I. This procedure will apply whether the multi party call is on hold or active, and whether
41、the single call is on hold or active. If the request is successful, previously held remote parties will receive an MPTY notification and a CallRetrieved notification as shown in figure 1.2, and previously active remote parties will receive an MPTY notification as shown in figure 1.3. If the network
42、did not receive a non-zero SS Screening indicator from the remote partys mobile station it shall not send a notification. If the request is unsuccessful e.g. because the maximum number of remote parties has already been reached, then an error is returned to the served mobile subscriber, as shown in
43、figure 1 .I. Error values are specified in TS GSM 04.80. 1.4.1.5 Alternate between the MPTY call and the single call This procedure follows the Alternate procedure defined in TS GSM 04.83 with the exception that the MPTY call is heldhetrieved using HoldMPTY/RetrieveMPTY in place of HOLD/RETRIEVE as
44、follows: Sinole call MPTY call (Facility) HOLD Invoke (HoldMPTY) HOLD ACKNOWLEDGE Return result HOLD REJECT Return error (error) RETRIEVE Invoke (RetrieveMPTY) RETRIEVE ACKNOWLEDGE Return result RETRIEVE REJECT Return error (error) Page 15 GSM 04.84 version 4.3.0 m 3404583 0105412 436 m 4 1.5 Adding
45、 extra remote parties Extra remote parties are added by placing the multi party call on hold (section 1.2.1.1 1, setting up a new connection (either a new call or a waiting call) and then sending a FACILITY message to the network requesting that the active call be joined with the MPTY, using the sam
46、e signalling as for invocation, see figure 1.1. This results in an active multi party call. Notifications are sent as for the initial invocation (.e. previously-held parties in MPTY receive CallRetrieved notifications and MPTY notifications; the new remote party only receives an MPTY notification),
47、see figures 1.2 and 1.3. If the network did not receive a non-zero SS Screening indicator from the remote partys mobile station it shall not send a notification. If the request is not accepted, e.g. because the maximum number of remote parties has already been reached, then the error is indicated to
48、 the mobile station. Error values are specified in TS GSM 04.80. 1.6 Auxiliary states for MPTY In the call hold service (TS GSM 04.831, a two dimensional state space is defined, where the first dimension corresponds to the GSM 04.08 call control state and the second dimension corresponds to the call
49、 hold state (Idle, Hold Request, Call Held, Retrieve Request). For the purposes of the MPTY service, it is necessary to introduce another dimension to this state space, .e. the multi party state. There are four auxiliary states associated with the MPTY service: Idle; MPTY request; A request has been made to add this call to the MPTY. Call in MPTY; This call is in the MPTY Split request; A reque
