BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a method of processing a mass concentration call using a service filtering technique in a telephone voting service or the like.

As the concept of intelligent network has been developed due to the development of network technology, the initial intelligent network has been established and the intelligent network service has been provided. However, as the demand of the communication user increases, the intelligent network service also needs to be diversified. In addition, the intelligent network is evolving from the initial intelligent network to the advanced intelligent network, and the standardization work is under way by the International Telecommunication Union Telecommunication Standardization Sector (ITU-T).

In the case of television voting (VOT) / Mass Calling (MAS) service, there is the characteristic of mass concentration call in which a large amount of intelligent network calls are generated within a few seconds after the service is started.

Accordingly, it is possible to efficiently process such a large-volume centralized call and efficiently transmit the signal traffic between the intelligent network nodes, that is, a service control point (hereinafter referred to as SCP) and a service switching point (hereinafter referred to as SSP) To prevent congestion, service filtering technique is used.

In the conventional massively concentrated call processing method, the call is blocked through the call congestion announcement in case of the non - intelligent network call, and the bulk call processing is performed using the call interception operation in the case of the initial intellectual network call. That is, in the case of an intelligent network call, the SCP downloads a part of the service logic possessed by the SCP to the SSP through the call blocking operation, the SSP has the SCP service logic, It is possible to process a large number of intelligent network calls.

Conventionally, a method of processing a bulk concentrated call by inserting bulk concentrated call processing information into a call blocking operation for overload prevention of the SCP is such that flexible processing for a bulk call is impossible when the call blocking operation is used, In addition to the fading of the original meaning, the intelligent network aims to provide the intelligent network service irrespective of the device provider, while the mass concentrated call processing method through the call blocking operation is also in violation of the intelligent network goal.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in an effort to solve the above problems, and it is an object of the present invention to provide a method for processing a bulk call using a service filtering technique in a telephone voting service having a large- have.

According to an aspect of the present invention, there is provided a method for processing a massively concentrated call applied to an intelligent network, the method comprising: generating, by a service controller, a bulk concentrated call parameter to transmit a service filtering activation operation to a service switching center; A first step of receiving the operation until the last response and storing the mass concentration call history; A second step of starting service filtering after storing the filtering parameters included in the service filtering activation operation received by the service switching system in the service switching system database; A third step in which the service exchange receives an intelligent network call from the local exchange and performs bulk concentrated call processing using a filtering reference parameter stored in the service switching center database; And a fourth step of storing the history of the filtered IN call in the service filtering response operation for a predetermined time after the service exchange stores the call history in the service exchange database and reporting the result to the service controller.

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

1 is a block diagram of an intelligent network for providing a telephone voting service to which the present invention is applied and includes a service controller (SCP) 1, a service management system (hereinafter referred to as SMS) 2, (Signaling Transfer Point) (hereinafter referred to as STP) (3). A service exchange (SSP) 4 and a local exchange (hereinafter referred to as LE) 5.

As shown in the figure, the SSP 4 recognizes the request of mass-concentrating call telephone voting service of the service user and triggers the corresponding service logic to request the SCP 1 to process the service through the STP 3, And the SCP (1). The SSP 4 in the intelligent network configuration assumes that it is not for local use but for the interfacing, and receives and processes the intelligent network service request from the local exchange (LE)

The SCP (1) is responsible for processing and controlling the bulk call voicemail service with the data required for service logic and service provisioning.

The SMS (2) is operated by the network operator and is responsible for managing the data and logic necessary to perform the service.

The STP 3 is responsible for transmitting the Signaling System (SS) No. 7 operation between the SCP 1 and the SSP 4. That is, the signaling method between SSP (4) and SCP (1) transmits and receives operation using SS No.7.

The signaling method between the SSP 4 and the LE 5 uses R2, a telephone user part (TUP), an ISDN user part (ISUP) 5) Use the DSSI or dual-tone multi-frequency (DTMF) signaling method.

The SCP 1 downloads the stored service logic to the SSP 4 in order to deal with a mass concentrating call in which the signal traffic between the SSP 4 and the SCP 1 bursts within a few seconds after the service is started in the intelligent intelligent network , The SSP 4 processes the bulk call without querying the SCP 1 according to the corresponding service logic.

First, the SCP (1) downloads the service logic to the SSP (4) using the service filtering activation operation. The SSP (4) receiving the service filtering activation operation processes a large number of intelligent network calls without querying the SCP (1) according to the parameters specified in the received service filtering activation operation, and stores the call history and the counter values.

In addition, the SSP 4 reports to the SCP (1) the history of the filtered intelligent network call for each specific interval or call count in the service filtering response operation.

When the service filtering is terminated, that is, when bulk call processing is terminated, the SSP reports the final history to the SCP (1) and deletes the service logic stored in its own database, respectively.

The service filtering activation operation for downloading to the SSP 4 provides information such as filtering call processing, filtering charging characteristics, time required for filtering, filtering reference, start time, and specifies parameters for mass concentration call processing. The service filtering response operation also provides counter values, filtering criteria, response conditions, and so on.

FIG. 2 is a flow chart of an embodiment of a method for processing a bulk concentrated call in a service controller (SCP) according to the present invention, in which a SCP generates a bulk call for a particular called party or a particular service, SCP is overloaded and massively concentrated call processing is started to prevent congestion of signal traffic.

As shown in the figure, the SCP generates a service filtering activation operation 100 consisting of a bulk concentration call parameter, i.e., filtering call processing, filtering characteristics, filtering time, filtering criterion, start time, Filtering here means that the SSP processes the call without querying the SCP for a bulk call destined for a particular called party or a particular service. In other words, the service logic that SCP has is SS No.7. By downloading to the SSP using the signal, it means that the SSP can perform the call processing without querying the SCP.

The filtering call processing parameter includes a filtering charging characteristic indicating a charging characteristic for a filtering call, transmission information indicating information such as tone, announcement, and the like, processing information for the filtering call, the maximum number of counters indicating the number of destinations to be included in the filtering, And release cause information indicating the release cause of the filtering call.

The filtering characteristic parameter is information indicating whether the SSP performs filtering based on the interval or the number of calls attempted.

The filtering time parameter is information indicating how long the service filtering should be performed.

The filtering reference parameter includes an input number, a calling subscriber number, a service key, an address (a called address value, a calling address value, a location number), and the like, indicating information on which object the SSP should perform filtering on.

The start time parameter indicates the time at which the SSP begins filtering for a bulk call.

Then, the SCP transmits massively concentrated call processing parameters to the SSP, including the bulk call processing parameters, to the service to be filtered in order to request the SSP for bulk concentrated call processing (101).

Thereafter, the SCP listens for a service filtering response operation from the SSP (102), receives a service filtering response operation from the SSP (103), and stores the filtered result in the SCP database (104). That is, a counter value for a bulk concentrated call, a filtered call history, and the like are stored.

The service filtering response operation includes a counter value for the filtered call, a filtering criterion for driving the SCP service logic, response condition information indicating whether the response is final or intermediate, and the like.

Thereafter, it is determined whether the response condition in the service filtering response operation is the final response (105). If it is the final response, the bulk centralized call processing is terminated. If not, the service filtering response operation reception procedure is repeated.

FIG. 3 is a flowchart of an embodiment of a bulk concentrated call processing method in a service switching system (SSP) according to the present invention.

As shown in the figure, the SSP receives (200) a service filtering activation operation from the SCP and stores the filtering parameters included in the service filtering activation operation in the SSP database and starts the service filtering activation process, i.e., service filtering (201).

Then, when the SSP waits for the reception of the intelligent network call from the LE (202) and receives the intelligent network call, it determines whether the received intelligent network call is a mass concentration call processing using the filtering reference parameter stored in the SSP database (203) If not, the general intelligent network call processing procedure is performed (204). If the bulk intensive call processing is performed, it is judged whether the filtering characteristic parameter, that is, the number of received calls is an arbitrary natural number N or the interval timer for distinguishing a certain amount of data, (205).

If the number of received calls is N or the interval timer is terminated, the SSP determines whether the number of received calls is N or any of the initial detection point operations and service Sends a filtering response operation to the SCP (206), initializes the filtering characteristic parameter (207), and enters a wait state (208) to receive the command from the SCP.

The SSP determines whether the number of received calls is an arbitrary natural number N or an interval timer for dividing a certain amount of data is terminated (205). If the number of calls is not N or the interval timer is not terminated, And stores the call history in the SSP database (Step 209). If the timer has not ended (Step 210), it waits for the reception of the intelligent network call repeatedly . If the timer has expired, the service filtering response operation is transmitted to the SCP (211), and the bulk concentrated call processing is terminated.

For reference, when a calling subscriber uses the telephone to make a telephone call to a called subscriber at the same time, most of the callers experience a telephone congestion state in which they can not make telephone calls with the called party. The exchange system, which is responsible for the exchange between the caller and the called party, informs the calling party that the caller is not able to connect to the called party due to call congestion and blocks calls when such call congestion occurs.

However, the telephone voting service is a service in which an unspecified number calls a specific called party to vote on items preferred by each caller and needs to be aggregated (collected), and a call congestion phenomenon, that is, .

For example, a program host will give you a phone number when you say you want to pick the best popular song from a live broadcast program. In addition, popular audiences will call the phone number they initiate and begin voting. At this time, the majority of the viewers will call the voting phone number simultaneously (from the start to the end of the popular broadcast) for a designated time, There are more people to leave. In other words, call congestion to a specific called party occurs, and the caller does not proceed with the counting of the call vote.

However, in the service filtering technique, when an unspecified number of callers are making a call to a specific called party, the calling system calls the caller who made the first call for a predetermined time (for example, 1 minute, 10 minutes) And other callers terminate the call after transmitting the call congestion announcement.

That is, the service filtering scheme connects the call only to the first call occurring during a predetermined time (filtering time) and ignores the remaining calls when the call is busy for a specific called party.

According to the present invention, when a large number of intelligent network calls are generated in the intelligent network composed of the intelligent network elements SSP, STP, and SCP, it is possible to prevent the congestion of the signal traffic by processing the intelligent network call without querying the SCP. The service provider can provide service to more users by applying it to the intelligent network service such as service, and the service provider not only improves the service quality due to the provision of more services, It is possible to prevent the phenomenon that the service is not served due to the congestion of the signal traffic, so that the service quality of the other intelligent network service can be improved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is not.
