16、1 Multi Party service (MPN) 1.1 Functions and information flows The following Mobile Additional Function has been identified for Multi Party service: MAF026 Multi Party service related authorizations examination The ability of a PLMN component to determine the authorizations relating to Multi Party
17、service (see figure 2.1). Location: VLR The overall SDL-diagram of Multi Party service is shown in figure 1.2. This overall SDL-diagram represents the network as a whole. The overall SDL-diagram shows the status of the service as perceived by the served mobile subscriber, as well as the status as pe
18、rceived by any of the other parties. Beside this, the overall SDL-diagram shows the actions to be taken by the network and the information provided by the network to the users. Within the authorization examinations diagram, the messages shown to and from the left are to and from the VLR. Within the
19、overall SDL diagram, messages to and from the served mobile subscriber are indicated to and from the left, whereas messages to and from remote parties are indicated to and from the right. The information flow for Multi Party service is shown in figure 1.3. - STD-ETSI GSN 03.84-ENGL L99b 3400855 0352
20、759 152 Page 8 GSM 03.84 version 5.0.0: December 1996 In 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 information flow diagrams it is assumed that there are only two remote part
21、ies. Where there are more than two remote parties, signals to any party connected to the MPTY bridge shall apply to all other parties connected to the MPTY bridge, except where a single remote party is to be selected for a private communication. As a consequence of this assumption, after the MPTY is
22、 split (to establish a private communication) it only contains 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 disconnection by a single remote party will not necessarily cause the MPTY c
23、all to be released. This will only happen when that remote party is the only remaining party in the MPTY call. Party A is the subscriber controlling the MPTY call (serviced mobile subscriber). Party B is the first remote party called. Party C is the second remote party called. Remote parties are dis
24、connected 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 diagrams for similar scenarios. Functions to be performed by the fixed IS
25、DN (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 Multi Party bridge is located in the MSC. In the SDL-diagrams a two dimensional state in conjunction with call hold is used: (activ
26、e,hold request). - The first dimension is a normal basic call state “active“ - The second dimension is “hold request“ (abbreviated hold res) meaning that a request has been made for the hold function. To avoid having two calls on hold at the same time the reception of the retrieve request is supervi
27、sed by timer T as defined in GSM 03.83. Note that while the Multi Party is on hold, the remote parties can continue to communicate with each other.

38、): Provisioning State Registration State Activation State HLR Induction State (Not Provisioned, Not Applicable, Not Active, Not Induced) (Provisioned, Not Appl kable, Active and Operative, Not Induced) The HLR shall store the logical state of MPTY (which shall be one of the valid states listed above
39、) on a per subscriber basis. 1.3 State transition model The following figure shows the successful cases of transition between the applicable logical states of MPTY. The state changes are caused by actions of the service provider. Note that error cases are not shown in the diagram as they normally do
40、 not cause a state change. Additionally, some successful requests may not cause a state change. Hence they are not shown in the diagram. Provision Withdrawal Figure 1.4: State transition model for MPTY 1.4 Transfer of information from HLR to VLR If the provisioning state for MPTY is “Provisioned“ th
41、en, when the subscriber registers on a VLR, the HLR shall send that VLR information about the logical state of MPTY. If the logical state of MPTY is changed while a subscriber is registered on a VLR then the HLR shall inform the VLR of the new logical state of MPTY. 1.5 Information stored in the VLR
42、 For MPTY the VLR shall store the service state information received from the HLR. 1.6 Handover Handover will have no impact on the control procedures and the operation of the service. 1.7 Simultaneous use of Multi Party operations The operations BuildMPTY, SplitMPTY, HoldMPTY and RetrieveMPTY inter
43、act with each other, and cannot be applied simultaneously. Once the mobile station has initiated one of these operations, it shall not initiate another Multi Party operation until the first operation has been acknowledged by the network, or the MS locally determines (due to timer expiry) that the first operation has failed.
