The present invention relates to a method for monitoring and controlling a centralized call of a communication network providing an intelligent network service.

The intelligent network is a newly proposed structural concept to provide a variety of value-added communication services using existing public telephone networks and common line signaling networks, and a new traffic control scheme is required to show traffic characteristics different from those of general telephone networks. For example, if a product sales company that subscribes to a terrestrial billing service, a toll-free commercial service, advertises a limited time special sale, a large number of calls can be concentrated on the subscriber's incoming line in a short time. When this condition occurs, partial congestion occurs in the communication network, which dramatically reduces the efficiency of related network resources, and when proper control is not performed, congestion may spread to the entire network.

Accordingly, an object of the present invention is to provide a method for automatically monitoring and controlling a centralized call on an intelligent network in order to prevent degradation of communication network performance due to an intelligent network service call.

In order to achieve the above object, the present invention provides a first step of retrieving a monitoring counter record of a corresponding subscriber from a centralized call monitoring table using a subscriber number as a retrieval key when a service is successfully processed, and a search result of the first step. And if the watch counter record does not exist, generating and ending a watch counter record of the subscriber in the centralized call watch table, and if the watch counter record exists, determining a mode designated by the watch mode value on the record; As a result of the determination in the second step, when the monitoring mode is the "central call mode", since it is already determined as the centralized call, the third step of immediately ending the call without other processing, and the determination result of the second step, the monitoring mode is " In the case of the centralized call mode, since it is determined that the centralized call is already called, the third step of immediately ending the call without any other processing and the second step As a result of the determination, when the monitoring mode is the "reading monitoring mode", the local count value is increased, and whether or not the count value reaches a certain amount of the concentrated call determination threshold is reached. The fourth step of converting the mode to the "mutual monitoring mode" and reporting its local count to the duplication module and ending; and if the monitoring mode is the "mutual monitoring mode", the local count is first Step 5 for checking whether the sum of the counts reported by the redundancy module of the local count has reached the centralized call determination threshold; and if the result of the check in the step 5 is reached or exceeded, Determining that there is a large number of concentrated calls, converting the watchdog mode to "central call mode" and reporting it to the redundant watchdog module For the subscriber determined as the centralized call, an automatic call blocking (ACG) is requested and the blocking cycle is calculated and registered in the ACG request table. Step 6 and Step 5 are performed. If, in the "interview mode", the subscriber has not yet reached the centralized emergency situation, it checks whether the local counter value corresponds to the cross-report cycle, and if the cross-report cycle corresponds, the local count is given to the redundancy module. Report and end as a message, and if not in the cross-report period characterized in that it comprises a seventh step to end immediately.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a hardware configuration diagram of a network information control system (NICS), which performs an intelligent network service control point function, to which the present invention is applied.

NICS, which performs service control point function as a node of common line signaling network, is a core device of intelligent network that has the function of monitoring and controlling the traffic control of intelligent network.

The NICS is a common line signal processor (CCP1, 2: Common Channel Signaling Processor, hereinafter referred to as "CCP") on which hardware and lower protocol processing software such as a common line signal link for CCITT No.7 protocol processing are mounted. Service Logic Processor (SLP) with processing and service logic software, and operation and management with software and user interface devices to provide system operation management and maintenance functions. It includes a processor (OAP: Operations and Administration Processor (OAP)) and a local area network (LAN) that provides an interconnect function therebetween. Among them, CCP, SLP, and LAN are redundant to improve usability and performance. In addition, reference numeral CMP denotes a CCS7 MTP (Message Transfer Part) Processor.

2 is a connection of a service traffic control block including a centralized call supervisory control function among a plurality of blocks constituting service logic and service logic which is an intelligent network service processing software provided in a redundant SLP of a NICS.

The service logic consists of a service function processing block, a service traffic control block, and a service measurement block.

The service traffic control block consists of a centralized call monitoring module and an automatic call blocking control module. The centralized call monitoring module is a module that monitors the case of successful processing of the intelligent network call every 5 minutes and determines whether the centralized call occurs.If it is determined as the centralized call, the ACG command is applied to the intelligent network service exchanger (SSP). The command details are registered in the ACG request table so that they can be sent to the Switching Point (hereinafter referred to as "SSP"). Automated blocking control module searches ACG request table and transmits ACG message for each SSP according to automatic call blocking control details requested from various causes including centralized call and deletes the contents from table after the validity period ends.

3 is a data structure diagram of a monitoring table in the centralized call monitoring module.

The centralized call monitoring table includes a subscriber number, a centralized call determination threshold, a local counter, a duplication module counter, and a monitoring mode.

The central call determination threshold is determined by the following equation as a reference value by determining whether or not the centralized call by subscriber.

Centralized call judgment threshold = number of actual incoming calls × 5 minutes per line allowed

The actual number of incoming calls refers to the number of lines allocated to the service subscriber for the call of the service by the subscriber who has subscribed to the wide area billing service and is designated by subscriber in the subscriber database. Call allowance per line for 5 minutes is a parameter that indicates the amount of service calls attempting to reach one line and is a parameter that can be adjusted by the operator.

The local counter is a counter in which the redundant service control module records its own measured traffic value, and the redundant module counter records the traffic value reported by the redundant state module.

The monitoring mode is for indicating the centralized call state transition, and the " interactive monitoring mode " for exchanging traffic data with the "ready monitoring mode " Concentrated arc mode ". The value of the watchdog mode sequentially shifts the values of these three modes, and starts from "reader watchdog mode" when the watch table is reset every 5 minutes.

4 is a control process flowchart of the centralized call monitoring and control method.

When the service is successfully processed, the subscriber counter is retrieved from the centralized call monitoring table using the subscriber number as a search key (1). If the search result watch counter record does not exist, the watch counter record of the subscriber is created and terminated in the centralized call watch table (2). At this time, the initial value is designated as the local count, the redundant module count is 0, and the monitoring mode is "reader monitoring mode".

If there is a monitoring counter record, the processing method is determined according to the monitoring mode value on the record (3). In the case of the "central call mode", since it is already determined as a centralized call, the process is terminated immediately without any other processing.

If the monitoring mode is " reader monitoring mode ", the local count value is increased (4), and it is checked whether the value has reached 1/2 of the concentrated call determination threshold (5). If it is not reached, the process ends, and if it is reached, the monitoring mode is switched to the "mutual monitoring mode" (6), and its local count is reported to the redundancy module and finished (7).

If the monitoring mode is " mutual monitoring mode ", the local count is first increased (8), and it is checked whether the sum of its local count and the count reported by the duplication module has reached the converged call determination threshold (9). If it has reached or exceeded, it is determined that a large number of centralized calls have occurred in the subscriber, and converts the monitoring mode to the "centralized call mode" (10) and reports it to the redundant monitoring module (11).

ACG is required for subscribers determined as centralized calls, and the blocking period is calculated so that the traffic for 5 minutes per subscriber is equal to the centralized call determination threshold (12). The formula is as follows.

Disconnection period (seconds) = (300 / Call Decision Threshold) × Number of active service switches (Active SSPs)

When the cutoff period is calculated, the control number in the ACG parameter is set to the subscriber number (e.g., 080- ×××-××××) and the cut-off time is determined by the system and registered in the AGC request table (13).

If the subscriber has not yet reached the centralized call state in the "supervision mode", it is checked whether the local counter value corresponds to the mutual reporting period (14). This is to prevent the performance degradation of the NICS caused by the increased traffic between the redundant processors when reporting at every count increase. If the cross-report period is applicable, the local module reports its local count as a message and ends (15), and does not correspond to the cross-report cycle and ends immediately (15).

Therefore, according to the present invention performed by the above processing procedure, if the centralized call generated at the time of providing the intelligent network service is appropriately blocked at the region close to the originating party, it prevents unnecessary occupancy of main network resources such as a trunk and reduces communication quality. In addition to providing a direct effect of preventing, one of the overloading factors of the signaling network and service control system that make up the intelligent network is eliminated, and these resource use opportunities for service subscribers can be more equalized.
