When a call is made to the called party and the called person hooks off the phone in response to the ring tone, the caller ID information is editable call announcement information, for example, the calling party number you requested is 000-0000. By providing as, it is possible for the called party to easily obtain information on the calling number that attempted the malicious call.

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

1 is a block diagram of an electronic switch in which the present invention is applied. As shown in the drawing, the electronic switch includes a matching exchange subsystem (hereinafter, referred to as a matching switch) that performs the overall function of localized call processing. ASS (Acess Switching Subsystem) (100, 100 '), an Interconnection Network Subsystem (INS) 200 that performs the overall functions of centralized call processing, and performs centralized operation and maintenance functions. It consists of three subsystems, which are called Central Control Subsystem (CCS) (not shown).

First, according to the figure, the ASS (100, 100 ') is matched to the subscribers, public telephone subscribers, PABX subscribers, and polarity under the control of the analog subscriber interface processor (ASIP; Analog Subscriber Interface (ASI) (1,1 ', 2,2') which performs functions (BORSCHT) for inversion, PPM transmission, etc., 20Hz call signal current and subscriber line circuit to send to incoming subscriber A ring generator (RG, 4,4 ') for generating a zero crossing (ZC) signal for contact protection of a ring relay of the relay and transmitting it to the ASI (1, 1', 2, 2 '); Signal service interface (hereinafter referred to as LSI) that processes DTMF (Dual Tone Multi-Frequency) signals from subscribers under the control of a Signal Service Processor (LSP (Local Service Processor) 8,8 ') and sends out various tones to subscribers. ; Local Service Interface (7,7 ') and time switch ring In addition to performing internal call processing under the control of a large processor (hereinafter referred to as TLSP (Time Switch and Local Signaling Procedure) (6, 6 '), the ASI (1, 1', 2, 2 '), LSI (7, 7) ') Is matched with the subhighway, and the Time Switching Link (TSL), which is matched with the INS 200 via an optical link for call processing to other subsystems or other exchanges, 5 '). Here, the TSL (5,5 ') performs time slot allocation and aggregation functions to the corresponding TSI (5,5') through timeslot switching (TSI), and inserts and extracts IPC data in the optical link matching function. Includes features.

On the other hand, the ASS (100, 100 ') is further provided with an access switch processor (hereinafter referred to as an ASP; Access Switch Processor) (100, 100') to collectively manage and manage the ASS (100, 100 ') and perform its own traffic processing function through a time switch. It is configured to include, wherein the ASP (10, 10 ') is further provided, wherein the ASP (10, 10') is the ASIP (3, 3 ') via a control interworking (CI) (9, 9') , TLSP (6,6 '), LSP (8,8').

In addition, according to FIG. 1, the INS 200 is configured to provide optical link matching with the TSL (5, 5 ') of the ASS (100, 100'). Control of a central data link (hereinafter referred to as CDL) 11 and a space switch processor 13 (hereinafter referred to as SSP) to perform a conversion function, an optical clock change function, and a data error detection function. A space division switch (SSW) 12 for performing a path change function and a space switching function between the TSL (5, 5 ') located at each ASS (100, 100') and a common service control processor (hereinafter GSP) Under the control of Gloval Service Processor (15), information (such as a changed telephone number, calling number, etc.) that subscribers want to know about services such as number change guide, missed call, call rejection guide, and caller ID guide assumed in the present invention; Editable recording guide that provides editing in the form of a syllable / word unit synthesized message in advance It consists of a device (hereinafter GSI; Gloval Service Interface) 14.

In addition, the INS 200 corresponds to a number translation request from each of the ASPs 10 and 10 ', and performs a number translation processor (NTP; 12) is further provided with an internal connection network processor (INP; Interconnection Network Process ssor 18) that performs a search and management function to the call using.

A brief description will be given of a general domestic call connection process of an electronic switch having the above-described configuration.

First, when the calling party B connected to the ASI 1 'dials the number for the subscriber A, the calling party ASP 10' determines whether the call is a domestic call or the last number if the call is a domestic call. After receiving the request for number translation to the NTP (17).

The NTP 17, which has received a number translation request from the calling party ASP 10 ', performs a translation operation on the called party number of the digit signal transmitted from the ASP 10' by the IPC function, and then the called party ASP. Ask (10) for an incoming call.

Meanwhile, the INP 18 requests the SSP 13 to access the SSW 12 and at the same time the originating ASP 10 'requests the TLSP 6' to connect the communication path. And, the called party ASP 10 requests the ASIP 3 to connect a ring to the called party, and the ASIP 3 is generated to the RG 4 in response to the request of the ASP 10. A ringing current of 20 Hz is sent to terminating subscriber A.

When the called party A hooks off the telephone in response to the ringer tone caused by the ringing current, the called party line condition is detected by the ASIP 3.

Thereafter, the called party ASP 10 requests the ASIP 3 to stop the ring and then informs the calling party ASP 10 'the answer of the called party.

Accordingly, when the called party ASP 10 requests the TLSP 6 to connect the communication path and the communication path is completed by the TSL 5, the calling party B and the called party A can perform a normal call. .

Hereinafter, a caller ID tracking service method in an electronic switching system according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG. 2.

First, while the subscribers A and B make a normal call through the above path (step 20), the ASP 10 tracks the calling party number from the called party A registered in the calling party number tracking service through the ASIP (3). The hook-fresh is monitored as requested (step 22).

On the other hand, if the call from the calling party B is about a normal call and a hook-fresh is not input from the called party A (NO in step 22), the ASP 10 determines whether the call of the A and B subscribers ends. If it is determined (step 24) that the hook-on state of the called party A is detected at the ASIP 3 or the hook-on state of the calling party B is detected at the calling ASIP 3 '(YES in the step 24), the ASP is determined. (10) determines that A and B subscribers have terminated the call and returns to the initial state.

On the contrary, when the calling party B attempts to make a bad call to the called party A, when the called party A operates the hook-switch and inputs the hook-fresh during the call, the input state of the hook-fresh is detected by the ASIP (3). When the status is reported to the ASP 10, the ASP 10 recognizes the request status of the caller ID tracking service (YES in step 22).

In response to the request state of the caller ID tracking service, the ASP 10 stores information data on the caller ID provided from the calling party ASP 10 'in built-in storage means (step 26).

Then, the ASP 10 determines whether the call of subscribers A and B is terminated (step 28), and the ASIP 3 detects the hook-on state of the called party A or the calling party ASIP 3 '. When the hook-on state of the calling party B is detected (YES in step 28), the ASP 10 determines that the call of the corresponding subscribers A and B is terminated and calls the called party A requesting the calling party tracking service. (Step 30).

That is, in step 30, the ASP 10 requests the TLSP 6 to establish a communication path, and at the same time, requests a ring back tone connection and rings the ASIP 3 to the subscriber. Request connection of (ring). In this case, the ASIP 3 transmits a ringing current of 20 Hz generated by the RG 4 to the subscriber A in response to a request of the ASP 10 so that a ring tone is transmitted to the subscriber A. FIG.

Subsequently, the ASP 10 determines whether the subscriber A responds (step 32). If the subscriber A hooks off the phone in response to the ringing tone (YES in step 32), the ASP 10 determines the TLSP. (6) requests the ASIP 3 to stop ringing at the same time as the ring back tone is cut off, and then the GSI 14 is driven through the GSP 15.

On the other hand, the GSP (15) is stored in the editable recording message for the call number guide, the GSP (15) edits the call number data transmitted from the ASP (10) to the edited recording message, for example The calling number you requested is 000-0000. Editing guide information is generated from the GSI 14 (step 34).

Subsequently, the INP 18 requests the SSP 13 to access the SSW 12 so that a communication path is set so that the editable recording guide information generated from the GSI 14, for example, the calling number requested by you Signal for 000-0000. Is transmitted to the TSL 5 of the ASS 100 via the CDL 11 through a communication path established by the SSW 12.

Then, the corresponding editable recording guidance information is transmitted to subscriber A through the communication path set by the TSL 5, so that announcement broadcast for the calling number requested by subscriber A is performed (step 36).

As described above, according to the caller ID tracking service method of the electronic switch according to an embodiment of the present invention, the pressurizer A registered in the caller ID tracking service receiving the malicious call hooks and flashes the caller during the call. When the service is requested, the telephone exchange automatically calls subscriber A at the end of the call to be traced, and if subscriber A hooks off the telephone in response to a call from the telephone exchange, then the tracked outgoing call is made. Edited recorded voice information for the number For example, the calling party number you requested is 000-0000. The subscriber A can easily identify the calling party number.

Therefore, according to the calling number tracking service method in the electronic switching system according to an embodiment of the present invention, a subscriber registered to the calling number tracking service hooks during a call to check the calling number using the calling number tracking service. -After the call, after the end of the call, the phone station to call the phone station to re-request the caller tracking number to eliminate the hassle of checking the caller ID.
