Another object of the present invention is: utilize the call flows of gatekeeper in the IP network, realize the CCF (CCF) among the SSP (Service Switching Point) under the IN service state, and still carrying out its function in former gatekeeper under the non intelligent service condition.
For achieving the above object, the technical solution used in the present invention is: the gatekeeper at IP network is provided with the Service Switching Point that comprises CCF (CCF) and SSF (Service Switching Function) that inserts with intelligent network.The CCF of set Service Switching Point connects in the free time of gatekeeper's call flows, analysis authentication, remote address translation, examination, connects, waits for and remove authentication, wait for chargeing and reply Intelligent Measurement dotted state of increase by six states outside; Be provided for detecting the preliminary examination test point DP3 of IN service in analysis authentication state static state, and be used to detect the detection of dynamic point DP10 that caller is abandoned; Be provided for detecting the detection of dynamic point DP4 and the DP10 of routing failure at remote address translation state; Connecting state in examination is provided with DP10, DP4, is used to detect the detection of dynamic point DP5 of Called Busy and is used to detect called unresponsive detection of dynamic point DP6; Be provided for detecting the detection of dynamic point DP7 that replys and the functional module that forms in connection status.Each state place in call flows, when an incident that meets trigger condition takes place on the test point that has been provided with, CCF reports the incident of detecting to SSF, the call flows of CCF is suspended the Intelligent Measurement dotted state, wait for the instruction of passing back via SSF at this state, if comprise request report BCSM (Basic Call State Model BCSM) incident in the instruction of returning, CCF disposes these test points according to command request, and jump to NextState from current Intelligent Measurement dotted state, continue the call flows of CCF.
SSP (Service Switching Point) is set in IP network, just as SSP is set in PSTN, solved the access from the IP network to the intelligent network, and SSP realized in the gatekeeper of IP network, utilize gatekeeper's call flows, when running into IN service, according to BCSM (Basic Call State Model BCSM) the completion status redirect that Q.1214 CS-1 provided of International Telecommunications Union about intelligent network; And when running into non intelligent business, keep original gatekeeper's function constant, and reduced the link of exploitation and operation, improved utilization rate of equipment and installations.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is gatekeeper's call flows figure.
Fig. 2 is the call flows figure that is provided with the gatekeeper of test point.
Among Fig. 1, gatekeeper's call flows comprises that free time, analysis authentication, remote address translation, the company of examination, connection, wait are removed and authenticated, six states are replied in the wait charging, according to the standard execution of service operation situation according to IP phone.Figure 2 shows that the gatekeeper's who is provided with test point call flows, when calling out to non intelligent business, the test point of all increases is not set up, and its state and flow process just are equal to original gatekeeper fully.
Below respectively with the call flows of gatekeeper the intelligent call of initiating and non intelligent calling the present invention from PC (personal computer) terminal.
Suppose a intelligent call, and hypothesis connects the success of state divert when busy call in examination from the PC terminal to phone.
1. the user inputs card number, password and called number on the PC terminal, makes a call to GK (gatekeeper).GK turns to the analysis authentication state from current idle condition after receiving the next calling of PC.
2.GK the card number password to the user authenticates, after authentication is passed through, and analyzing called number, because this calling is an IN service, GK sends to SSF and detects initial DP incident, turns to the Intelligent Measurement dotted state.
3.GK receive the connection passed back via SSF from SCP and the operation of request report BCSM incident, requirement according to RRBE is configured to dynamic requests type test point with DP5, GK carries out address translation according to the called number that provides in the attended operation to it, send authentication by message to the PC terminal after translating successfully, turn to even state of examination.
4.GK receive from the foundation of PC terminal and call out the connection signaling, GK is to this signaling of called forwarding, and then GK receives the ring signaling from called gateway, and GK transmits this signaling to caller, around here, call state remains unchanged, and then receives the call release signaling from called gateway, and release cause is a Called Busy, GK reports DP5 to detect incident to SSF, transmit the call release signaling to caller, and remove the configuration that this DP is ordered, turn to the Intelligent Measurement dotted state.
5.GK receive the attended operation of passing back via SSF, GK carries out address translation according to the transferred number that provides in the attended operation, translates successfully the back and sends authentication by message to the PC terminal, turns to examination to connect state.
