For making the object of the invention, technical scheme and advantage clearer, the present invention is made further detailed description below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of dynamic forwarding method based on service agent of the present invention includes:
To service agent Service Broker (being called for short SB), several professional institutes that SB contracts to the user by relative trigger priority corresponding service control point SCP respectively trigger successively with call for step 1, MSC/SSP;
Step 2, when SB when triggering last cover SCP, whether the business function of all SCP that triggered before judging all triggers, if the call signaling Handover that then MSC/SSP is sent (i.e. switching) is to a last cover SCP;
Step 3, MSC/SSP and said last cover SCP directly carry out Signalling exchange, and Service Broker withdraws from current dialogue, and promptly the Signalling exchange between MSC/SSP and the SCP no longer passes through SB.
As shown in Figure 2, said step 1 further includes:
Said step 1 can also include: SB monitors the echo message of SCP, and when the echo message of SCP was the Continue message of TC-End mode, the business function that then writes down said SCP did not trigger.
Further say; Whether SB can also be triggered to the business function of all SCP through the service trigger mode bit identifies; Like this in step 2, the value that detects the service trigger mode bit as SB is not when triggering, and the business function of all SCP that triggered before can judging all triggers.Wherein, whether SB is triggered to the business function of all SCP through the service trigger mode bit identifies, and further includes:
Steps A 1, SB are made as not triggering (as 0 or 1) with the initial value of service trigger mode bit;
Do steps A 2, SB judge that the echo message of SCP is the Continue message of TC-End mode? If, explaining that then the business function of SCP is not triggered, SB continues the echo message of next cover SCP is monitored execution in step A2; If not, explain that then the business function of SCP has been triggered, the said service trigger mode bit of SB is set to trigger (as 1 or 0), and this flow process finishes.
In the said step 2; SB overlaps SCP with the call signaling Handover that MSC/SSP sends to last one; Further include: SB sends IDP message to said last cover SCP with TC-Begin; And SCCP SCCP layer source address filled out the global title GT address into MSC/SSP, and SCCP layer destination address filled out the GT address into said last cover SCP, and said source address and destination address are all according to the addressing of GT mode.Like this; After said last cover SCP receives the IDP message of SB with the TC-Begin transmission; Find that the SCCP source address is the GT address of MSC/SSP, so to the MSC/SSP echo message time, be the GT address of said last cover SCP to the address that MSC/SSP confirms; Thereby the Signalling exchange of MSC/SSP and said last cover SCP can directly be skipped SB, realizes the function of Handover.
What deserves to be mentioned is; In the existing network technology; If SB triggers many cover SCP, SB will be earlier to MSC/SSP send a RRBE (its English full name is: RequestReportBCSMEvent) (O/T-Abandon) message, according to relative trigger priority all SCP are triggered again.And in the method for the invention, then do not need to send RRBE (O/T-Abandon) message to MSC/SSP.
As shown in Figure 3, a kind of dynamic adapting system based on service agent of the present invention includes MSC/SSP, SB and some cover SCP, and said MSC/SSP, SB and SCP link to each other through network.As shown in Figure 4, said SB further includes:
Dynamically the Handover processing unit is used to receive the call message that MSC/SSP sends, and by triggering priority the pairing some covers of user's signing service service control point (SCP) is triggered successively; When triggering last cover SCP; Whether the business function of all SCP that triggered before from SCP business monitoring record cell, judging does not all trigger; If; The call signaling switching Handover that then MSC/SSP is sent overlaps SCP to said last, thereby makes MSC/SSP and said last cover SCP directly carry out Signalling exchange;
SCP business monitoring record cell be used to receive the echo message of SCP, and when said echo message was the Continue message of TC-End mode, the business function that writes down said SCP did not trigger.
As shown in Figure 5, said dynamic Handover processing unit can further include Handover decision means and Handover Message Processing parts, wherein:
The Handover decision means; Be used for when triggering last cover SCP; Whether the business function of all SCP that triggered before judging does not all trigger, if then notify said last cover of Handover Message Processing parts subtend IDP message that SCP will send to handle;
Handover Message Processing parts; Be used for the notification instruction sent according to the Handover decision means; The SCCP SCCP layer source address of the IDP message of using TC-Begin to send filled out the global title GT address as MSC/SSP, and SCCP layer destination address filled out the GT address into said last cover SCP.
Said SCP business monitoring record cell can also include:
Service trigger mode bit management component; Be used for the initial value of service trigger mode bit is not made as triggering; And when the echo message that monitors SCP is not the Continue message of TC-End mode; Said service trigger mode bit is set to trigger, and whether wherein said service trigger mode bit is used for business function to all SCP and is triggered and identifies.
As shown in Figure 6, be example with the signatory VPMN of user and two business of arrearage control, to the further illustrated in detail of the present invention.Because the professional existence of VPMN is chargeed, and need control service trigger prior to arrearage.What dial is in the crowd during user if the user is current, processing such as the VPMN service needed is chargeed, the number of changing, and like this, two business of VPMN and arrearage control all will be triggered, and SB needs while and VPMN, arrearage to control professional SCP to carry out alternately; Outside the user dials the crowd during user; Processing such as the VPMN business need not chargeed, the number of changing; The professional SCP of VPMN will be to SB loopback Continue (TC-End) message; This moment, SB only needed the direct Handover of IDP message is controlled on the professional SCP to arrearage, i.e. MSC/SSP and arrearage controlled and directly carried out Signalling exchange between the professional SCP.When Fig. 6 shows the user and dials the outer user of crowd, adopt the Signalling exchange figure of an existing network technology and a calling procedure embodiment of the present invention's technology respectively, can find out obviously that wherein (a) employing existing network is technological, the signaling number that SB need handle is 18; (b) adopt the present invention's technology, the signaling number that SB need handle is 4 and existing network compared with techniques, and the present invention can save several 14 of signaling.In like manner, concerning a called flow, the present invention can save several 12 of signaling.Like this, if existing network has the user of 1,000,000 signatory VPMN and arrearage control, every general-purpose family is adjusted by 5CAPS, and intra-group call is according to 30% ratio, and calling and called calculated according to 1: 1.After using technology of the present invention, per second SB can reduce the signaling number of handling and be: (500*70%) * (14+12)/2=4550, through application of the present invention, can greatly effectively reduce the complexity of SB signaling process and unnecessary signaling link expense.
