Abstract

The invention discloses a soft switch service delayed triggering method, and relates to a network technology. In the method, a new detection point (DP), namely, a transaction detection point (TRDP), and a new service delayed triggering method are adopted; and the method can be used for making use of the traditional operation of an intelligent network CS-2 so as to conveniently realize complex conference service logics such as an MEETME conference, a PRESET conference and the like. The TRDP is associated with two DPs, a service is detected on one DP point, and subsequently a service logic is triggered on the other DP to realize the delayed triggering. The service triggered by a plurality of TRDPs is processed in a same service logic example. According to the invention, the complexity in realizing the service logic is reduced, and the service development period is shortened.

Description

Soft switch service delayed triggering method

Technical field

The present invention relates to next generation network technology, especially a kind of soft switch service delayed triggering method of realizing.

Embodiment

The present invention is described in detail below in conjunction with drawings and Examples.

The triggering method of embodiment 1:PRESET convention business

Several conferenced partys have been preset in the PRESET meeting, dial the meeting room number by the meeting promoter and initiate the PRESET meeting, then form meeting by the participant in the service logic call-conference.Any one calling party of while can be dialed PRESET meeting room number and add meeting.For convenience of description, sign A is the meeting promoter, and B and C are for presetting conference member, and D adds the calling party of meeting by dialing the meeting room number.

The triggering method of PRESET convention business comprises the steps:

Step 1: delayed trigger affairs test point (TRDP) is set, its related two DP points, detecting the DP point is " analysis _ information " DP point, triggering the DP point is " terminal _ call attempt " DP point; " analysis _ information " DP point is front, and " terminal _ call attempt " DP point is rear;

Step 2: call handling process is carried out a DP point;

Step 3: judge whether current DP point is " analysis _ information " DP point; When being, call handling process is carried out following step 4; When not being, call handling process is carried out following step 7;

Step 4: judge whether current calling parameter mates with the trigger criteria of assignment in advance; If coupling, call handling process is carried out following step 5; If do not mate, call handling process is carried out following step 7;

Step 5: judge whether current DP vertex type is TDP; If not, call handling process is carried out following step 6; If so, call handling process is carried out following step 10;

Step 6: current DP point is TRDP, and mark PRESET convention business detects in call context, be recorded in simultaneously " terminal _ call attempt " DP point and trigger service logic;

Step 7: call handling process proceeds to next PIC point;

Step 8: call handling process proceeds to next DP point;

Step 9: judge whether this DP point is " terminal _ call attempt " DP point; If not, call handling process turns to carries out described step 7; If so, call handling process is carried out following step 10;

Step 10: trigger the PRESET convention business, produce a PRESET convention business logical instance;

Step 11: judge whether current DP point is request type DP point; If so, call handling process is carried out following step 12; If not, call handling process turns to carries out described step 7;

Step 12: call handling process rests on this DP point, the indication of latency services logic.

The described DP of detecting point and triggering DP point all belong to OBCSM, perhaps all belong to TBCSM, and perhaps one belongs to OBCSM, and one belongs to TBCSM.

The concrete handling process of said method as shown in Figure 1.Call out the CVS view of control this moment as shown in Figure 2.In figure, the left side is view corresponding to A, and the right side is operational view corresponding to PRESET meeting, is referred to as PRESET_1.The purpose that TRDP is arranged on the trigger point " terminal _ call attempt " just is to generate operational view corresponding to PRESET meeting, facilitates later use " mobile calls section " and " merging call leg " operation to realize meeting.The following description of detailed process.

After the service logic example produces, call " startup call attempt " operation and call out successively B and C, call out the CVS view of control this moment as shown in Figure 3.In figure, the first row is the view that A dials PRESET meeting room number, i.e. view shown in Figure 2; The second row is the view that service logic is called out B, and wherein PRESET_2 is view corresponding to PRESET meeting in calling out; The third line is the view that service logic is called out C, and wherein PRESET_3 is view corresponding to PRESET meeting in calling out.When B replied, at first the service logic example called " mobile calls section " operation, the call leg in PRESET_2 is moved in PRESET_1, and then PRESET_1 is carried out " merging call leg " operation.Form AB two side's meetings this moment, call out the CVS view of control as shown in Figure 4.When C replied, at first same service logic example called " mobile calls section " operation, the call leg in PRESET_3 is moved in PRESET_1, and then PRESET_1 is carried out " merging call leg " operation.Form 3 side's meetings this moment, call out the CVS view of control as shown in Figure 5.

After forming 3 side's meetings, D adds this meeting by dialing the meeting room number, and the process that business triggers is the same during with the A initiating conference, and the CVS view as shown in Figure 6, has equally also generated operational view PRESET_4 corresponding to PRESET meeting relevant to D at this moment.When operation layer receives that this TRDP triggers, can process in current service logic example, can not generate new service logic example.This moment, at first the service logic example called " mobile calls section " operation, the call leg in PRESET_4 is moved in PRESET_1, and then PRESET_1 is carried out " merging call leg " operation.Form 4 side's meetings this moment, call out the CVS view of control as shown in Figure 7.
