Embodiment
Example below in conjunction with accompanying drawing and called user selecting payment service will be described in further detail the present invention.
Of the present inventionly carry out in communication process that caller collects the digits or the called control method that collects the digits, make intelligent network platform in communication process, can receive caller or called key information, its core concept is: when caller and incoming call, the method of service control point by registration basic call incident will need the touch-tone signal informing business exchange point monitored, Service Switching Point is monitored speech channel, the touch-tone signal of registration occurs in speech channel after, Service Switching Point reports to the touch-tone signal that occurs registration in the service control point speech channel.Like this, reach the purpose of when caller and incoming call, obtaining user key-press information, as shown in Figure 2.
The specific implementation step of the inventive method is as follows:
The first step: the access code of intelligent network business is dialed in caller, inserts intelligent network business;
Second step: intelligent network business is carrying out alternately with caller, receives information such as called number;
The 3rd step: intelligent network business is operated to Service Switching Point registration caller MidCall, called MidCall incident by " the request report basic call incident " of intelligent network application protocol (INAP signaling), and the user key-press that needs to monitor carries with the parameter of these two incidents; After Service Switching Point receives this operation, extract the information of monitoring dual-tone multifrequency;
The 4th step: intelligent network business is connected called by the attended operation informing business exchange point of INAP signaling; Behind called off-hook, the name a person for a particular job voice channel time slot of Incoming of operation exchange is broadcast to out voice channel time slot and dual-tone multifrequency digit receiver time slot, described voice channel time slot can for caller to called time slot, also can be for being called into the time slot of caller;
The 5th step: after the dual-tone multifrequency of registration occurring in the speech channel, dual-tone multifrequency digit receiver informing business exchange point, Service Switching Point pass through " basic call event report " the operational notification service control point generation caller MidCall or the called MidCall incident of INAP signaling again.Service control point has just been known the dual-tone multifrequency that user key-press takes place according to the log-on message before continuing, and has just realized during caller and incoming call, and intelligent network business obtains caller or called key information; Next, the intelligent network business service logic that just can continue has subsequently realized different business functions.
Since can there be echo in the speech channel, the dual-tone multifrequency information that said method receives, and it is from caller or from called that Service Switching Point can't clearly be distinguished.This method is improved, can also be implemented in the calling, receive only the function of caller or called key information.Its core concept is: increase an echo and suppress module in speech channel, the caller button or the called button echo that occur in the inhibition speech channel, like this, in the speech channel of same direction, the dual-tone multifrequency digit receiver just can only receive the key information of this direction, as shown in Figure 3, Figure 4.
Its specific implementation step is as follows:
The first step: the access code of intelligent network business is dialed in caller, inserts intelligent network business;
Second step: intelligent network business is carrying out alternately with caller, receives information such as called number;
The 3rd step: intelligent network business is operated to Service Switching Point registration caller MidCall, called MidCall incident by " the request report basic call incident " of INAP signaling, and the user key-press that needs to monitor carries with the parameter of these two incidents; After Service Switching Point receives this operation, extract the information of monitoring dual-tone multifrequency;
The 4th step: intelligent network business is connected called by the attended operation informing business exchange point of INAP signaling; Behind called off-hook, operation exchange name a person for a particular job Incoming voice channel time slot with broadcasting mode be linked into out voice channel time slot and dual-tone multifrequency digit receiver time slot, if caller MidCall incident in the registration of the 3rd step, then voice channel time slot is that called voice channel time slot is arrived in caller, if registration is called MidCall incident, then voice channel time slot is for being called into the caller voice channel time slot; Only the caller button is monitored if desired, then register caller MidCall incident, local exchange is gone into the receive direction of relaying or the sending direction of out-trunk carries out the echo inhibition; Only called button is monitored if desired, then register called MidCall incident, local exchange is gone into the sending direction of relaying or the receive direction of out-trunk carries out the echo inhibition;
The 5th step: after the dual-tone multifrequency of registration occurring in the speech channel, dual-tone multifrequency digit receiver informing business exchange point, Service Switching Point pass through " basic call event report " the operational notification service control point generation caller MidCall or the called MidCall incident of INAP signaling again.Service control point has just been known the dual-tone multifrequency that user key-press takes place according to the log-on message before continuing, just know that according to the incident that Service Switching Point reports the caller button still is called button, so just realized that during caller and incoming call intelligent network business control obtains caller or called key information; Next, the intelligent network business service logic that just can continue has subsequently realized different business functions.
The called user selecting payment service flow process as previously mentioned, the inventive method can realize receiving called information by the # key.Owing to will get rid of the interference of caller, need echo to suppress the cooperation of module by the # key.
As shown in Figure 5, its concrete treatment step is as follows:
The first step: Calling Side is dialed access code, and Call Control Block sends originated call message and gives Service Switching Module according to access code;
Second step: Service Switching Module is according to start message, session of beginning message (TC_BEGIN) beginning with transaction capabilities agreement (TCAP), send " initialization calling " signaling (argument structure of signaling referring to ITU-T Q.1218) of intelligent network application protocol to service control point, trigger corresponding intelligent network business;
The 3rd step: message control module is monitored the callee side button in the back of continuing according to service logic judgement needs, can not be subjected to simultaneously the interference of Calling Side button, message control module is registered called MidCall incident by " request report basic call incident " operation of intelligent network application protocol to Service Switching Module; Its LegID parameter is set to 13, and the button that expression is monitored is the # key; Owing to need only monitor the callee side button, echo need be suppressed block configuration for the receive direction of caller to the sending direction of Service Switching Point relaying or Service Switching Point to called relaying carried out the echo inhibition, see also shown in Figure 3;
The 4th step: message control module sends attended operation to Service Switching Module, connects called by Service Switching Module controlling call control module;
The 5th step: the Call Control Block transmission is set up number receiving resource message and is given resource module, and resource module is sought the dual-tone multifrequency digit receiver time slot of a free time and set up number receiving resource message gap information is passed to Call Control Block by replying;
The 6th step: Call Control Block is broadcast to caller time slot and number receiving resource time slot with called time slot in the mode of broadcasting;
The 7th step: after called button # number, dual-tone multifrequency digit receiver notice resource module, resource module is notified to Call Control Block to send key information;
The 8th step: Call Control Block sends basic call event report message, passes to message control module by Service Switching Module, after message control module receives this incident, triggers the event handling flow process of called MidCall; Call Control Block after the resource module releasing operation is finished, is finished message to the Call Control Block response by discharging the number receiving resource that number receiving resource message informing resource module discharges the application of the 5th step;
The 9th step: after called and caller conversation are finished, message control module sends intelligent network application protocol " release " operation and gives Service Switching Module, Service Switching Module notification call control module discharges this calls out, and message control module is returned end (TC_END) that Service Switching Module sends the transaction capabilities agreement and finished the session that second step set up.
So the inventive method has just realized that IN service has been finished the irrealizable business in common intelligent network environment as called user selecting payment so only at caller or called reception user key-press information in calling procedure.
Should be understood that above-mentioned description at the specific embodiment of the invention is comparatively concrete, can not therefore be interpreted as the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
