And to a method.

The main concept of Incoming Call Screen (ICS) and Outgoing Call Screen (OCS) is how to terminate a call or process announcements without processing a specific number to limit incoming or outgoing calls to a specific RTE at the exchange. . This method is generally used as a technique for managing the RTE in the exchange.

When a call processing request comes to the incoming RTE, the ICS checks and blocks the restricted called station number (called PFX) in the filtering table. This feature can be implemented differently by each manufacturer or software developer, but the result is the same. That is, there is a problem in that the place where the filtering table is managed or the object to be judged may be different.

The OCS checks and blocks the restricted calling station number (outgoing PFX) in the filtering table in the ASP before sending a call from the outgoing RTE to another exchange. This feature can be implemented differently by each manufacturer or software developer like ICS, but the result is the same. That is, there is a problem in that the place where the filtering table is managed or the object to be judged may be different.

Accordingly, the present invention is to solve the above problems, to complement the call restriction function by the intelligent network server, to manage the illegal end to block illegal calls, and to immediately terminate the abnormally generated call It is an object of the present invention to provide an RTE call control system and method of an exchange.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment of the present invention will be described in detail.

1 is a diagram illustrating an RTE call control system of an exchange of the present invention. As shown in FIG. 1, the RTE call control system of the exchange of the present invention includes an input access switching processor (iASP) 100, a number translation processor (NTP) 200, and an oASP 300. The iASP 100 includes a call processing processor 110 and a filtering table 120, and the oASP 300 includes a call processing processor 310, a filtering table 320, and an LCS function processor 330. .

The iASP 100 receives the call connection request of the calling number (or called number) according to the specification of the trunk signal in the RTE.

The call processing processor 110 present in the iASP 100 assigns a Job_ID, an IPC, a Queue, or a Process_ID (child number, memory address, RTE number, or digit information) to the call and generates a child processor.

The child processor compares the calling number (or called number) of Job_ID, IPC, Queue or Process_ID with the calling number (or called number) of filtering table 120, and the calling number (or called number) of Job_ID, IPC, Queue or Process_ID. If is not in the filtering table 120, the calling number (or called number) or Process_ID is sent to the NTP. However, the child processor compares the calling and called numbers of Job_ID, IPC, Queue, or Process_ID with the calling and called numbers of filtering table 120, and compares the calling and called numbers of Job_ID, IPC, Queue, or Process_ID with filtering table ( 120), it is determined to be an abnormal call and deletes Job_ID, IPC, Queue or Process_ID and terminates. At the end, the calling party number (or called party number) is printed or a log is left in the system.

The filtering table 120 has information on the calling number and the called number, and the calling number and the called number are compared with the calling number (or called number) of Job_ID, IPC, Queue or Process_ID by the child processor.

The NTP 200 receives the calling number (or called number) or Process_ID from the child processor of the iASP 100 and performs normal call processing.

The oASP 300 receives a call connection request of the calling number (or called number) or Process_ID from the iASP 100 after the NTP 200 performs normal call processing with the iASP 100.

The call processing processor 310 present in the oASP 300 assigns Job_ID, IPC, Queue or Process_ID to the call and creates a child processor.

The child processor compares the calling number (or called number) of Job_ID, IPC, Queue or Process_ID with the calling number (or called number) of filtering table 320, and the calling number (or called number) of Job_ID, IPC, Queue or Process_ID. If is not in the filtering table, the child processor sends the calling number (or called number) to the other exchange for normal call processing. However, the child processor compares the calling and called numbers of Job_ID, IPC, Queue, or Process_ID with the calling and called numbers of filtering table 320 to compare the calling and called numbers of Job_ID, IPC, Queue, or Process_ID with filtering table ( 320), the child processor determines that it is an abnormal call and deletes Job_ID, IPC, Queue or Process_ID and terminates. At the end, the calling party number (or called party number) is printed or a log is left in the system. In addition, the child processor receives the call processing information output signal of the LCS function processor 330 to receive the call processing information (call number, called number, RTE number or call time, reason) managed by Process_ID to the system console (console). Print or log the system.

The LCS function processor 330 checks Process_ID and periodically manages a start time for each Process_ID, and calculates a difference between the start time and the current time of the Process_ID (current time-start time) and compares it with the value of the filtering table 320. do. Here, since the current time is later than the start time, the current time always has a value greater than zero. If the difference between the start time of the Process_ID and the current time is greater than the value of the filtering table 320, the LCS function processor 330 outputs call processing information (call number, called number, RTE number, or talk time) to the child processor. Send a signal However, if the difference between the start time of the Process_ID and the current time is smaller than the value of the filtering table 320, the process_ID periodically has a difference until the difference between the start time and the current time of the Process_ID is greater than the value of the filtering table 320. The difference between the start time and the present time (current time-start time) is calculated and compared with the values of the filtering table 320.

2 is a view showing a limited call screen (LCS) method of the present invention. The LCS method allows the calling party number and called party number to be filtered by a specific RTE in the exchange so that a particular calling party number (or number) is not called by a particular called party number (or number), and the mobile phone number (HLR) manages the mobile number. It is a method for processing in an exchange even without using a specific additional service such as a home location register).

In the case of the LCS method, a filtering table for the calling number and the called number must be created in advance. The filtering table manages various resources such as a specific file, DB, and memory, and the processor creates and manages a child processor during call processing.

First, a call connection request of an originating number or a called number is received by an iASP according to a specification of a trunk signal in an RTE (S100).

Next, the call processing processor present in the iASP to the call allocates Job_ID, IPC, Queue or Process_ID and generates a child processor (S110).

Next, the child processor compares the calling number of Job_ID, IPC, Queue or Process_ID with the calling number of the filtering table (S120).

Next, if the calling number of Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the calling number to NTP for normal call processing (S130). However, if the calling number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor compares the called number of Job_ID, IPC, Queue or Process_ID with the called number of the filtering table (S140).

Next, if the called number of Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the called number to NTP for normal call processing (S150). However, if the called number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor determines that it is an abnormal call and deletes Job_ID, IPC, Queue or Process_ID and terminates (S190). At the end, the caller ID or caller ID is printed or the system logs.

Next, NTP performs normal call processing with iASP (S160).

Next, after NTP performs normal call processing with iASP, oASP receives a call connection request of calling number, called number or Process_ID from iASP (S170).

Next, the call processing processor present in the oASP to the call allocates Job_ID, IPC, Queue or Process_ID and generates a child processor (S180).

Next, the child processor compares the calling number of Job_ID, IPC, Queue or Process_ID with the calling number of the filtering table (S200).

Next, if the calling number of Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the calling number to another exchange for normal call processing (S210). However, if the calling number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor compares the called number of Job_ID, IPC, Queue or Process_ID with the called number of the filtering table (S220).

Finally, if the called number of Job_ID, IPC, Queue, or Process_ID is not in the filtering table, the child processor sends the called number to another exchange for normal call processing (S230). However, if the called number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor determines that it is an abnormal call and deletes Job_ID, IPC, Queue or Process_ID and terminates (S240). At the end, the caller ID or caller ID is printed or the system logs.

The LCS method can be applied differently for each RTE and can be simultaneously applied to originating and incoming calls. In addition, the ICS (Incoming Call Screen) and OCS (Outgoing Call Screen) functions used in the exchange can be used alone, but can be applied simultaneously by integrating into the LCS function.

3 is a view showing a call management method for a specific time or more of the present invention. The call management method for a specific time or longer provides information to process and determine abnormal call when the call is over a specified time in a specific RTE of the exchange, and it takes a long time by acquiring the calling number, called number and call time which are information provided by the exchange. This is how you handle calls.

In the case of a call management method for a specific time or more, a filtering table for a duration time must be created in advance. The filtering table manages various resources such as a specific file, DB, and memory, and the processor generates and manages a child processor during call processing. The LCS function processor in the ASP functions as a log call check.

Call management method for more than a certain time is that iASP receives a call connection request of calling number (or called number) according to the trunk signal specification in RTE so that NTP receives calling number (or called number) or Process_ID from iASP. After the process is performed until the normal call processing, the operation method is as follows.

First, after NTP performs normal call processing with iASP, oASP receives a call connection request of calling number, called number, or Process_ID from iASP (S170).

Next, the call processing processor present in the oASP to the call allocates Job_ID, IPC, Queue or Process_ID and generates a child processor (S180).

Next, the LCS function processor checks Process_ID and periodically manages a start time for each Process_ID (S300).

Next, the LCS function processor calculates a difference value (current time-start time) between the start time and the current time of Process_ID and compares the value with the value of the filtering table (S310). Here, since the current time is later than the start time, the current time always has a value greater than zero.

Next, if the difference between the start time of the Process_ID and the current time is greater than the value in the filtering table, the LCS function processor signals the child processor to output call processing information (call number, called number, RTE number, or talk time). S320). However, if the difference between the start time and the current time of Process_ID is less than the value in the filtering table, periodically the start time and the current time of Process_ID are not until the difference between the start time and the current time of Process_ID is greater than the value in the filtering table. The difference value (current time-start time) is calculated and compared with the value in the filtering table.

Finally, the child processor receives the call processing information output signal of the LCS function processor and outputs the call processing information (call number, called number, RTE number or talk time, reason) managed by Process_ID to the system console or the system. Leave a log on (S330).

It is possible to improve the problem that the call management method for a certain time is applied to the existing system collectively, and it can be optimized for multiple RTE because it can be managed differently for each RTE. In addition, the long-term call management in the existing exchange is not limited by RTE because the exchange is collectively managed for a specific time, but can be managed and applied to individual times for each RTE.

4 is a diagram showing a PPS abnormal international call processing method of the present invention. The PPS abnormal international call processing method monitors using the LCS method and the call management method for a certain time when the PPS subscriber uses an abnormally unacceptable phone, and when the call processing is performed at the exchange, the contents of the intelligent network server are limited. Find and monitor unfiltered problems.

In case of handling PPS abnormal international call, filtering table for calling number, called number or duration should be created for LCS and call management function for more than a certain time. The filtering table manages various resources such as a specific file, DB, and memory, and the processor generates and manages a child processor during call processing. The LCS function processor in the ASP functions as a log call check.

In the PPS abnormal international call processing method, the iASP receives the call connection request of the calling number (or called number) according to the trunk signal specification in the RTE so that the NTP receives the calling number (or called number) or Process_ID from the iASP. After the process to the normal call processing is possible, the following operation method is as follows.

First, after NTP performs normal call processing with iASP, oASP receives a call connection request of calling number, called number, or Process_ID from iASP (S170).

Next, the call processing processor present in the oASP to the call allocates Job_ID, IPC, Queue or Process_ID and generates a child processor (S180).

Next, the LCS function processor checks Process_ID and periodically manages a start time for each Process_ID (S400).

Next, the child processor compares the calling number of Job_ID, IPC, Queue or Process_ID with the calling number of the filtering table (S410).

Next, if the calling number of Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the calling number to another exchange for normal call processing (S420). However, if the calling number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor compares the called number of Job_ID, IPC, Queue or Process_ID with the called number of the filtering table (S430).

Next, if the called number of Job_ID, IPC, Queue or Process_ID is not present in the filtering table, the child processor sends the called number to another exchange for normal call processing (S440). However, if the called number of Job_ID, IPC, Queue or Process_ID is in the filtering table, the child processor determines that it is an abnormal call and deletes Job_ID, IPC, Queue or Process_ID and terminates (S500). At the end, the caller ID or caller ID is printed or the system logs.

Next, the LCS function processor calculates a difference between the start time of the Process_ID and the current time (current time-start time) and compares the result with the value of the filtering table (S450). Here, since the current time is later than the start time, the current time always has a value greater than zero.

Next, if the difference between the start time of the Process_ID and the current time is greater than the value in the filtering table, the LCS function processor signals the child processor to output call processing information (call number, called number, RTE number, talk time or reason). Send (S460). However, if the difference between the start time and the current time of Process_ID is less than the value in the filtering table, periodically the start time and the current time of Process_ID are not until the difference between the start time and the current time of Process_ID is greater than the value in the filtering table. The difference value (current time-start time) is calculated and compared with the value in the filtering table.

Next, the child processor outputs call processing information (call number, called number, RTE number, call time or reason) managed by Process_ID to the system console or leaves a log in the system (S470).

Next, upon termination request with call processing information (ASP information, calling number or called number) by the operator request (calling number or called number), the processor receives this and sends a termination signal to the child processor (S480).

Finally, the child processor outputs call processing information (ASP information, calling number or called number) and ends (S490).

PPS abnormal international call processing can be managed for the supplementary function of the intelligent network call restriction function and specific service, and it is possible to immediately terminate the call that occurred for a long time. It is also possible to immediately end a call for a long time.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the technical spirit of the present invention through the above description. Therefore, the technical scope of the present invention should not be limited only to the contents described in the embodiments, but should be defined by the claims.

As described above, the RTE call control method of the exchange according to the present invention has the following effects.

First, the LCS (Limitative Call Screen) method can restrict the call at the end of the interworking line between the operators, so that the exchange can filter at the condition that is not removed from the authentication server, and for specific originating and incoming calls As it can be applied in common, it can be added and deleted by the operator.

Second, by using the call management method for a specific time, it is possible to improve the problems caused by the existing batch application by applying different time periods for each time limiting element, and to manage abnormal long time calls for each RTE. Can be tracked.

Third, by using the PPS abnormal international call processing method, the call restriction function by the intelligent network server can be supplemented, and the last step is managed by the RTE to block illegal calls, and the abnormally generated call can be terminated immediately.

A first step in which the oASP receives a call connection request of any one of a calling number, a called number, or a Process_ID from the iASP after the NTP performs normal call processing with the iASP; A second step of assigning any one of Job_ID, IPC, Queue or Process_ID by the call processing processor existing in the oASP to the call and generating a child processor; A third step in which the LCS function processor periodically checks Process_ID and manages a start time for each Process_ID; A fourth step of the child processor comparing the calling number of any one of Job_ID, IPC, Queue or Process_ID with the calling number of the filtering table; If any originating number among Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the originating number to another exchange for normal call processing, and any originating number among Job_ID, IPC, Queue or Process_ID A fifth step of the child processor comparing the called number of any one of Job_ID, IPC, Queue or Process_ID with the called number of the filtering table if the filtering table is present; If any called number among Job_ID, IPC, Queue or Process_ID is not in the filtering table, the child processor sends the called number to another exchange for normal call processing, and any called number among Job_ID, IPC, Queue or Process_ID A sixth step in which the child processor determines that the call is an abnormal call and deletes any one of Job_ID, IPC, Queue, or Process_ID and terminates if it is in the filtering table; A seventh step of the LCS function processor calculating a difference value between a start time and a current time of Process_ID and comparing the value with a value of a filtering table; If the difference between the start time and the current time of the Process_ID is greater than the value of the filtering table, the LCS function processor signals the child processor to output call processing information, and the difference between the start time and the current time of the Process_ID is determined by the filtering table. If the value is less than the value, the difference between the start time and the current time (current time-start time) of Process_ID is calculated periodically until the difference between the start time and the current time of Process_ID is greater than the value in the filtering table. An eighth step of comparing; A ninth step of receiving, by the child processor, a call processing information output signal and outputting call processing information managed by Process_ID to a system console or leaving a log in the system; A tenth step in which the processor receives the termination request with the call processing information by the calling number or the called number and sends a termination signal to the child processor; And An eleventh step of the child processor outputting and terminating call processing information; RTE call control method of the exchange comprising a. The method according to claim 5, The call processing information is any one of a calling number, called number, RTE number, call time or reason.
