Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram of an exchange for performing an intelligent network call tracking method according to the present invention, a personal machine interface (hereinafter referred to as PMI) 100, a call trace and path configuration management unit (Call Trace and Path). Set up Management (hereinafter abbreviated as CTPM) 110, Number Data Handling (hereinafter abbreviated as NDH) 120, Relay Call Control and ISDN User Part Control (hereinafter referred to as TKC / UPC (130), and intelligent network service (Service Filtering and Call Gapping (hereinafter SSFC) 140).

2 is a flowchart illustrating a method for registering an intelligent network call tracking service for performing an intelligent network call tracking method according to the present invention.

The registration method shown in FIG. 2 will be described with reference to FIG. 1.

First, when the intelligent network call tracking registration is requested from the PMI 100 in step 202, the CTPM 110 proceeds to step 204 to analyze the authorized intelligent network call tracking registration request message. In other words, it analyzes the condition message for the call to be traced, such as the syntax for the authorized message and which intelligent network call is required.

In step 206, the CTPM 110 checks whether an INP (not shown) provided in the NDH 120 is normal. If the INP (not shown) is normal, the process proceeds to step 208 and requests registration of the tracking function for the intelligent network call requested by the NDH 120. Accordingly, the NDH 120 registers a tracking function for the intelligent network call. The registered result is transmitted to the CTPM 110.

When the CTPM 110 receives the result of registering the intelligent network call tracking function in step 210, the CTPM 110 outputs a message indicating that the tracking function for the corresponding intelligent network call is registered to the PMI 100, and the intelligent network call tracking is performed. End the function registration.

When performing the tracking function registration for the intelligent network call, if the check result of step 206 determines that the INP not shown is abnormal, the CTPM 110 proceeds to step 212 and the INP registers the tracking function registration result for the intelligent network call. It outputs a message that it is impossible to register because it is abnormal, and finishes the registration process of intelligent network call tracking function.

3 is a flowchart illustrating a tracking method for an intelligent network call according to the present invention.

The operation of the tracking method for the intelligent network call shown in FIG. 3 will be described with reference to FIG. 1.

First, when a predetermined intelligent network call is generated from the TKC / UPC 130 in step 304 while the CTPM 110 maintains the standby state in step 302, the CTPM 110 proceeds to step 306 through step 304. It proceeds to and checks whether the tracking function for the currently generated intelligent network call is registered with reference to the NDH (120).

As a result of the check, if the tracking function for the currently generated intelligent network call is not registered, the TKC / UPC 130 proceeds to step 308 to perform the corresponding intelligent network call processing as before, and the call processing is completed when the call processing is completed. End the job.

However, if the tracking function for the currently generated intelligent network call is registered as the check result of step 306, the CTPM 110 proceeds to step 310 and performs the corresponding intelligent network call processing normally and maintains the tracking result reception state. .

At this time, when the INP (not shown) provided in the NDH 120 refers to the NDH 120 in the TKC / UPC 130, the TKC / UPC 130 is used when the intelligent network call is a call registered with a tracking function. The tKC / UPC 130 reports the tracing registration for the intelligent network call to SSFC 140. Accordingly, the TKC / UPC 130 and the SSFC 140 transmit the traced results to the CTPM 110 in units of call in point and monitoring point.

At this time, the contents of the call processing point that can be tracked are as follows.

1) O_Null _ & _ Auth_Orig_Atmpt: When the previous call has been truncated and released, or the exception has been processed by CCF / SSF.

2) Collect_Information: The caller requests the call and the calling qualification / capability is successful.

3) Analysis_Information: When initial information is collected from the calling party.

4) Routing_and_Alerting: When routing address and call type are decided.

5) O_Action: When a busy response is received from the called BSCM.

6) O_Exception: An exception occurs in all call processing points of the originating BSCM.

7) T_Null _ & _ Auth_Term_Atmpt: The previous call was disconnected and cleared or the exception was handled by CCF / SSF.

8) Select_Facility _ & _ Present_Call: When the incoming signal such as ring to the called party is sent.

9) T_Alerting: In case of receiving incoming signal such as ring to called party.

10) T_Active: The called party responds.

11) T_Exception: An exception occurred in all call processing points of the destination BSCM.

In addition, the content of the detection point is as follows.

1) Orig_Atmpt_Authorized_DP: Receives an event that the calling party is instructed to initiate a call and that the calling party has been verified to be able to initiate a call.

2) Collected_Info_DP: Receives an event from the calling party that initial information package / dialing string collection is completed.

3) Analyzed_Info_DP: Receive event from the originator that initial information package / dialing string collection is completed.

4) Route_Select_Failure_DP: Receives an event that a route cannot be selected or a call cannot be sent from the called BCSM to the called party due to network congestion.

5) O_Called_Party_Busy_DP: Receive event that called party is busy from called BCSM.

6) O_No_Answer_DP: Event that the called party does not respond within the specified time from the called BCSM.

7) O_Answer_DP: Receives an event from the incoming BCSM indicating that the call was received and answered at the called party.

8) O_Disconnect_DP: Receive event that disconnect from calling party or called party.

9) O_Abandon_DP: Receive event when caller gives up call.

10) Term_Attempt_Auth_DP: Instructed to receive a call and receiving an event that the credentials have been verified to route the call to a specific incoming resource.

11) T_Call_Party_DP: Event that all resources in the group are in use or busy.

12) T_No_Answer_DP: Receives an event that the called party did not respond within a certain time.

13) T_Answer_DP: Received an event that the call was received by the called party and the called party answered.

14) T_Disconnect_DP: Event that disconnected from originating party or called party is received

15) T_Abandon_DP: Receive event that call is abandoned at originating party.

Only the "Collected_Info_DP" of the above-described content of the detection point is tracked by the SSFC 140, and the rest are tracked by the TKC / UPC 130. The tracking result is sent to the CTPM 110 in units of call processing points or detection points that are subjected to the intelligent network call processing.

On the other hand, when the CTPM 110 receives one tracked result message from the TKC / UPC 130 or the SSFC 140 while controlling the corresponding intelligent network call processing, the process proceeds to step 314 through step 312. Analyze the received trace result message. The analysis then analyzes whether the tracking results are normal.

In step 316, the CTPM 110 transmits the analyzed result to the PMI 100 and counts the number of traced messages. This allows the operator to grasp the progress of the current intelligent network call.

CTPM 110 then proceeds to step 318 and compares the counted tracked message number with a predetermined threshold. This predetermined threshold is applied when the operator registers the tracking function for the intelligent network call. As a result of the comparison in step 318, if the number of tracking messages is smaller than the predetermined threshold, the process proceeds to step 320 and it is checked whether the intelligent network call processing currently in progress is terminated. As a result of the check, if the intelligent network call processing that is currently in progress is not completed, the process proceeds to step 312 to maintain the reception standby state.

However, if the intelligent network call processing that is currently in progress is terminated as a result of the check in step 320, the process returns to step 302 to maintain the standby state. As a result of the comparison of step 318, if the number of currently counted tracking messages is greater than or equal to a predetermined threshold value, the flow proceeds to step 322 to cancel the registration of the intelligent network tracking function and terminate the operation. At this time, the registration of the intelligent network tracking function can be made at any time by the request of the operator through the PMI (100).

As described above, the present invention tracks an intelligent network call processing state by call processing point and detection point unit in an exchange that can provide an intelligent network service, thereby allowing an operator to control the flow of a desired intelligent network call regardless of a complete call or incomplete call. As it can be understood in detail, there is an effect that can improve the operating efficiency of the system. In particular, in case of an incomplete call, there is an advantage that an operator can easily grasp unavailability information of system resources.
