Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of dynamic forwarding method based on service agent of the present invention, includes:
Step 1, MSC/SSP are triggered to service agent Service Broker (being called for short SB) by calling, and several business that SB contracts to user by the corresponding triggering priority institute respectively service control point (SCP) of correspondence triggers successively;
Step 2, when SB is when triggering last a set of SCP, whether the business function of all SCP that trigger before judgement does not all trigger, if so, the call signaling Handover MSC/SSP being sent (i.e. switching) is to last a set of SCP;
Step 3, MSC/SSP and described last a set of SCP directly carry out Signalling exchange, and Service Broker exits current dialogue, and the Signalling exchange between MSC/SSP and SCP no longer passes through SB.
As shown in Figure 2, described step 1 further includes:
Step 11, MSC/SSP send IDP to SB, and (its English full name is: InitialDP) message;
Described step 1 can also include: SB monitors the echo message of SCP, and when the echo message of SCP is the Continue message of TC-End mode, the business function that records described SCP does not trigger.
Further, SB can also trigger mode bit by business whether the business function of all SCP is triggered and is identified, like this in step 2, when SB detects value that business triggers mode bit when not triggering, the business function of all SCP that trigger before can judging is triggering all.Wherein, SB triggers mode bit by business whether the business function of all SCP is triggered and is identified, and further includes:
The initial value that steps A 1, SB trigger mode bit by business is made as not triggering (as 0 or 1);
Do steps A 2, SB judge that the echo message of SCP is the Continue message of TC-End mode? if so, illustrate that the business function of SCP is not triggered, SB continues the echo message of lower a set of SCP to monitor, execution step A2; If not, illustrate that the business function of SCP has been triggered, the described business of SB triggers mode bit and is set to trigger (as 1 or 0), and this flow process finishes.
In described step 2, the call signaling Handover that SB sends MSC/SSP is to last a set of SCP, further include: SB sends IDP message to described last a set of SCP with TC-Begin, and SCCP SCCP layer source address filled out to the global title GT address into MSC/SSP, SCCP layer destination address filled out the GT address into described last a set of SCP, and described source address and destination address are all according to the addressing of GT mode.Like this, when described last a set of SCP receives after the IDP message of SB with TC-Begin transmission, find the GT address that SCCP source address is MSC/SSP, so when to MSC/SSP echo message, the GT address that the address of confirming to MSC/SSP is described last a set of SCP, thereby the Signalling exchange of MSC/SSP and described last a set of SCP can directly be skipped SB, realizes the function of Handover.
It is worth mentioning that, in existing network technology, if SB triggers many cover SCP, SB will be first sends a RRBE to MSC/SSP, and (its English full name is: RequestReportBCSMEvent) (O/T-Abandon) message, more all SCP are triggered according to corresponding triggering priority.And in the method for the invention, 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 described MSC/SSP, SB are connected by network with SCP.As shown in Figure 4, described SB further includes:
Dynamic Handover processing unit, the calling triggering message of sending for receiving MSC/SSP, and by triggering priority, the corresponding some covers of user's signing service service control point (SCP) is triggered successively; When triggering last a set of SCP, whether the business function of all SCP that trigger before judgement from SCP business monitoring record cell does not all trigger, if, the call signaling switching Handover MSC/SSP being sent arrives described last a set of SCP, thereby makes MSC/SSP and described last a set of SCP directly carry out Signalling exchange;
SCP business monitoring record cell, for receiving the echo message of SCP, and when described echo message is the Continue message of TC-End mode, the business function that records described SCP does not trigger.
As shown in Figure 5, described dynamic Handover processing unit can further include Handover decision means and Handover Message Processing parts, wherein:
Handover decision means, for when triggering last a set of SCP, before judgement, whether the business function of all SCP of triggering does not all trigger, and if so, notifies the IDP message that last a set of SCP will send described in Handover Message Processing parts subtend to process;
Handover Message Processing parts, for the notification instruction of sending according to Handover decision means, the SCCP SCCP layer source address of the IDP message sending with TC-Begin filled out to the global title GT address into MSC/SSP, and SCCP layer destination address filled out the GT address into described last a set of SCP.
Described SCP business monitoring record cell can also include:
Business triggers mode bit management component, for business being triggered to the initial value of mode bit, be not made as triggering, and when monitoring the echo message of SCP and not being the Continue message of TC-End mode, described business triggers mode bit and is set to trigger, and wherein said business triggers mode bit for whether the business function of all SCP is triggered and is identified.
As shown in Figure 6, it is example that two business are controlled in the signing VPMN of the user of take and arrearage, and the present invention is further explained in detail.Because VPMN business exists charging, need to trigger prior to arrearage service control.If user is current dial be user inside the group time, VPMN service needed is carried out the processing such as charging, the number of changing, like this, VPMN and arrearage are controlled two business and all will be triggered, SB needs while and VPMN, arrearage service control SCP to carry out alternately; When user dials user outside the group, VPMN business does not need to carry out the processing such as charging, the number of changing, VPMN business SCP will be to SB loopback Continue (TC-End) message, now SB only need be upper to arrearage service control SCP by the direct Handover of IDP message, between MSC/SSP and arrearage service control SCP, directly carries out Signalling exchange.When Fig. 6 shows user and dials user outside the group, adopt respectively the Signalling exchange figure of a calling procedure embodiment of existing network technology and the technology of the present invention, can obviously find out, wherein (a) adopts existing network technology, and the signaling number that SB need process is 18; (b) adopt the technology of the present invention, the signaling number that SB need process is 4, compares with existing network technology, and the present invention can save 14 of signaling numbers.In like manner, concerning a called flow, the present invention can save 12 of signaling numbers.Like this, if the user that existing network has 1,000,000 signing VPMN and arrearage to 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.Use after the technology of the present invention, SB per second can reduce the signaling number of processing and be: (500*70%) * (14+12)/2=4550, by application of the present invention, can greatly effectively reduce the complexity of SB signaling processing and unnecessary signaling link expense.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
