Step 12, calling party entity notice application server begin conversation;
Behind step 13, the end of conversation, the Soft core call controller reports charge information by agent entity to calling entity;
Step 14, calling entity notice application server charge information;
Step 15, Soft core call controller report end of call event through agent entity to calling entity;
From said process as seen, agent entity is received and dispatched corresponding message by to the method call towards the CORBA entity, thereby has realized the conversion of general service interface message and third party's business interface message.Wherein, step 1,4,6,8,9,10,11,13 and 15 related message are general-purpose interface message, and step 2,3,5,7,12,14 and 16 related message are the message of application server interface.
Referring to shown in Figure 4, Fig. 4 is for providing the architectural schematic of soft switch general-purpose interface to the INAP gateway.Because INAP gateway and soft switch general-purpose interface all adopt message mechanism, therefore finish the conversion of INAP message and soft switch general-purpose interface message by Proxy.
Below to realize that business procedure is that example illustrates the adaptive of message between INAP interface and the soft switch general-purpose interface.
Referring to shown in Figure 5, in the Parlay gateway, comprise agent entity, in realizing business procedure, set in advance the Event triggered point, the process of interacting message is as follows between INAP interface and the soft switch general-purpose interface:
Step 1, Soft core call controller are to the agent entity reported event;
Step 2, agent entity are notified application server, and event occurs;
Application program in step 3, the Service Control Point is provided with the charging plan and reports agent entity;
Step 4, agent entity will be provided with the charging plan and send to the Soft core call controller;
Step 5, service control point are to the agent entity acquisition charge information that initiates a message;
Step 6, agent entity obtain charge information with message and send to the Soft core call controller;
Step 7, service control point are provided with dynamic trigger point, and information reporting Basic Call State Model BCSM (BCSM) incident;
Step 9, agent entity are provided with dynamic trigger point, and are sent to the Soft core call controller;
Step 10, service control point are to agent entity message route;
Step 11, agent entity are created the message that corresponding CallLeg is connected to calling with step 8 and are sent to the Soft core call controller;
Step 12, Soft core call controller report the called party answer incident;
Step 13, agent entity informing business control point begin conversation;
Behind step 14, the end of conversation, the Soft core call controller reports charge information to agent entity;
Step 15, agent entity informing business control point charge information;
From said process as seen, the traditional business interface message is corresponding one by one with general service interface message.Wherein, step 1,4,6,8,9,11,12 and 14 related message are general-purpose interface message, and step 2,3,5,7,10,13,15 and 16 related message are the message of service control point.
As seen, various interface message comprises following three classes from above-mentioned message adaptation procedure:
(1) is applied in calling, the enterprising behaviour part registration of calling party; The dependent event that takes place on calling, the calling party is reported to application;
(2) for the intervention and the control of the state transitions of individual call side; Intervention and control for the state transitions of whole calling are actually intervention and control to incidence relation between the calling party that participates in this calling;
(3) application is provided with the charging relevant information; With charge information is reported to application.
The definition of above-mentioned interface message, follow following principle:
At first, consider that Parlay MPCC API and INAP interface all adopt Event triggered setting-reporting events mechanism, soft switch general service interface message also adopts Event triggered setting-reporting events mechanism.Be compatible multiple interfaces, adopt to dynamically arrange point (EDP) and static set-point (TDP) two kinds of Event triggered set-up modes.
Secondly, with the residing state of a side in the calling of calling party (leg) state representation, with the incidence relation of different calling party and calling in the calling (call), as connected, released or the like represents the association between the calling party.For the control of calling party state transitions, show as call accepted side's status report and indicating call side and carry out state transition; For the control of incidence relation between the calling party in calling out, show as between the call accepted side that incidence relation changes between the incidence relation status report and indicating call side.And in message definition, reserved enough allowings for expansion and guaranteed the control in the future free position shifted.
Above-mentioned each message function is all realized by the message body in the message format.Referring to shown in Figure 6, Fig. 6 is the message format of general service interface message.Above-mentioned various message constitutes by message header and message body.Wherein, message header comprises:
Call identification (Call ID) is used for both sides of unique sign or Multi-Way Calling, distinguishes the message that belongs to same call.This parameter has uniqueness, uses the each side of this message should determine separately range of distribution in advance, and the mode of suggestion can be: the calling that every network is initiated, and Call ID is distributed by soft switch; Every professional control program is the calling that the third party initiates, and Call ID is distributed by the gateway of this business procedure correspondence;
Sub-call identification (Sub Call ID) is mainly used under the conference model sign of the calling party in the son conference that coexists;
Caller identification (Call Party ID) is used for identifying a calling party, distinguishes the message that belongs to same call side, and it is unique in same calling;
Application identities (Appilication ID) is distinguished a plurality of application programs that participate in providing business;
Type of message (Msg Type) is in order to the type of message according to the content different identification correspondence of message body.
Message body length (Msg Length), the length of message body (byte number);
Association identification (Correlation ID) is used to identify the association between the message of paired appearance, and the correlation ID of paired message should be consistent.
The content of message body is different along with the difference of type of message, from above-mentioned classification, can comprise:,, and charge information and information gathering report message body are set for the control messages body of calling or calling party state transitions to the setting and the response message body of call event.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
