Method of Call Blocking and Call Filtering in Intelligent Network

The present invention relates to a method for call blocking and call filtering in an intelligent network, and in particular, to instruct a call blocking or call filtering process in a corresponding intelligent network to an intelligent network processor designated as a master to perform a corresponding call blocking or call filtering process in each corresponding intelligent network processor. The present invention relates to a method for call blocking and call filtering in an intelligent network.

In order to reduce the time and cost of designing and implementing a new service in the exchange and to provide services more efficiently by separating the parts in charge of various services in the conventional exchange and implementing them in general hardware and software, Advanced Intelligent Network (hereinafter referred to as 'Intelligent Network') was introduced, and by building the intelligent network in general hardware and software environment, the latest technology is rapidly introduced to meet the rapidly evolving computer technology to improve the performance of the exchange. Can be facilitated.

In such an intelligent network, different intelligent network elements are connected to each other to provide various services and perform call blocking or call filtering as needed. In particular, a service requiring such call blocking or call filtering is required. Is a telephone voting service (Televoting Service) and a Mass Calling Service (Mass Calling Service).

Here, the telephone voting service assigns one or several numbers to the service subscribers, and then allows the service user to attempt a call and select a specific advertised number so that the service provider can provide statistical results for each selection for a certain period of time. It is a service that informs subscribers, and is used to collect opinions on major issues related to new advertisements, administration, etc., or conduct mock ballots before elections. Should be considered.

The mass calling service is a service that connects a call to an appropriate destination according to routing conditions such as geopolitical location or time when a large number of call requests are concentrated to one or several destinations for a short time. Statistical information on service usage can be informed from the intelligent network.

Call Gapping and Call Filtering processing structures in a general intelligent network are shown in FIG. 1 as shown in FIG. 1, as shown in FIG. 1, a Service Control Point (hereinafter referred to as an 'SCP') (11). ), An advanced intelligent network processor (hereinafter referred to as 'AIP') 12 and a call control function (hereinafter referred to as 'CCF') entity 13 .

The SCP 11 instructs the AIP 12 to perform call filtering or call blocking for a particular service.

The AIP 12 performs call filtering or call blocking processing on the call transmitted from the CCF entity 13 according to the call filtering or call blocking instruction of the SCP 11.

The CCF entity 13 collects caller information for the attempted call from the subscriber and forwards it to the AIP 12.

Call blocking and call filtering operations in the conventional intelligent network configured as described above are as follows.

First, if the call blocking operation in the intelligent network is described, the SCP 11 detects the congestion state of the central processing unit or if the artificial call blocking instruction by the operator is detected, the call blocking is performed by the AIP 12. In this case, the CCF entity 13 collects caller information such as caller ID or caller ID for the attempted call from the subscriber and delivers the caller information to the AIP 12.

Accordingly, the AIP 12 analyzes the call blocking instruction of the SCP 11, that is, the transmitted call blocking message, and checks the blocking condition, the blocking instruction condition, and the blocked call processing method, and according to the confirmed result. The call blocking function for the call transmitted from the CCF entity 13 is performed. In this case, the AIP 12 performs a call blocking operation for a predetermined time to block the transferred call and simultaneously remove the CCF entity 13. Through the broadcast corresponding to the caller will be sent.

Next, describing the call filtering operation in the intelligent network, the SCP 11 activates service filtering with the AIP 12 to perform a filtering function for a call requesting a specific service. In this case, the AIP 12 analyzes SCP 11's call filtering instruction, i.e., transmitted ASF message, to filter conditions, filtering time, filtering method, and filtered call processing method. After confirming, and performing the call filtering function according to the confirmed result, the CCF entity 13 collects the caller information, such as the calling number or the called number for the attempted call from the subscriber and forwards it to the AIP 12 Accordingly, the AIP 12 performs a call filtering operation according to a predetermined filtering period time or a filtering lake, so that the service filtering response includes the filtered lake as a response to the corresponding ASF message. (Service Filtering Response; hereinafter referred to as 'SFR') to send a message to the corresponding SCP (11) and to send the announcement to the caller of the attempted call through the CCF entity 13, and to perform the billing process Directed to the CCF entity 13.

However, since the call blocking and call filtering operations in the conventional intelligent network as described above are performed by one intelligent network processor, when the corresponding intelligent network processor is down or a failure occurs, the call blocking and call filtering operations are restored until normal return. There was a problem that can not be performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to designate a master intelligent network processor in an intelligent network including a plurality of intelligent network processors for performing call blocking and call filtering processing, and the other intelligent network processor in the corresponding master intelligent network processor. By performing the appropriate call blocking and call filtering processing while managing the status of these devices through periodic heartbeats, it is possible to perform stable and efficient call blocking and call filtering processing.

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

The call blocking and call filtering processing structure in the intelligent network according to the present invention has an SCP 21, an intelligent network processor 22, and a CCF entity 23, as shown in FIG. The intelligent network processor unit 22 is composed of a master AIP 22-1 designated as a master by the SCP 21, and a plurality of slave AIPs 22-2 to 22-n not designated as masters.

The SCP 21 designates any one AIP constituting the intelligent network processor unit 22 as the master AIP 22-1, and calls filtering or call blocking for a specific service with the designated master AIP 22-1. Instruct the execution of.

The intelligent network processor 22 performs call filtering or call blocking for the call transmitted from the CCF entity 23 according to the call filtering or call blocking instruction of the SCP 21, and the master AIP 22-1. Generates a corresponding indication message according to the call filtering or call blocking instruction of SCP 21, and announces the master identification number to each slave AIP (22-2 to 22-n) together with the generated indication message. Perform call filtering or call blocking processing. Each of the slave AIPs 22-2 to 22-n performs a corresponding call filtering or call blocking process according to an indication message known from the master AIP 22-1, and periodically transmits its own state information. Delivers to the master AIP 22-1 via a bit (HeartBeat).

The CCF entity 23 collects caller information on the attempted call from the subscriber and delivers the caller information to each AIP 22-1 to 22-n of the intelligent network processor 22.

Call blocking and call filtering operations in the intelligent network according to the present invention configured as described above will be described with reference to FIG. 3.

First, SCP 21, which instructs call blocking or call filtering for the intelligent network processor 22 in the corresponding intelligent network, designates any one AIP as the master AIP 22-1 according to its master designation priority ( Step S31), the designated master AIP 22-1 is instructed to call blocking or call filtering for the specific service (step S32).

Accordingly, the master AIP 22-1 generates the corresponding indication message, that is, the call blocking message or the call filtering message according to the call blocking or call filtering instruction of the SCP 21 (step S33), and then generates the indication message. The master identification number is then announced to each slave AIP 22-2 to 22-n (step S34).

Then, each of the slave AIPs 22-2 to 22-n transmits its status information according to the master identification number known from the master AIP 22-1 through the corresponding heartbeat (HeartBeat). -1) and simultaneously perform call filtering or call blocking processing using caller information on a call delivered from CCF entity 23 according to an indication message announced from master AIP 22-1. In this case, the master AIP 22-1 performs call blocking or call filtering processing that it should perform.

Subsequently, the master AIP 22-1 analyzes the state information transmitted from each slave AIP 22-2 to 22-n to determine whether a failure occurs in each of the slave AIPs 22-2 to 22-n. It confirms (step S35).

If it is confirmed that the corresponding slave AIP (22-2 to 22-n) does not fail, the corresponding master AIP (22-1) and each slave AIP (22-2 to 22-n) are the corresponding call blocking or call filtering. If the slave AIP 22-2 to 22-n fails, the master AIP 22-1 regenerates an indication message according to the call blocking or call filtering instruction of SCP 21. (Step S36), the regenerated instruction message is notified to each slave AIP 22-2 to 22-n except for the failing slave AIP (step S37), so that the corresponding master AIP 22-1 and each slave AIP ( 22-2 ~ 22-n), the call blocking or call filtering process is restarted due to the failure of the slave AIP.

Meanwhile, call blocking and call filtering operations in an intelligent network according to the present invention will be described in more detail as follows.

First, the call blocking operation in the intelligent network, first, when the SCP 11 detects the congestion state of the central processing unit or when the artificial call blocking instruction by the operator is detected, the intelligent network processor 22 Instructing the call blocking to the master AIP (22-1), at this time, call blocking conditions such as service, call number, called number, call blocking instruction conditions such as duration, blocking cycle time, artificial call blocking, Call blocking control type for automatic call blocking and information on blocked call processing methods such as announcements are transmitted to the corresponding master AIP 22-1.

Then, the master AIP 22-1 generates a corresponding indication message, that is, a call blocking message according to the call blocking instruction of SCP 21, and then generates a call blocking message and a master identification number for notifying that the master is a master. Is known to each slave AIP (22-2 to 22-n), and the call blocking message includes information on a call blocking condition, a blocked call processing method, and a call blocking cycle time calculated according to the number of AIPs. Included.

At this time, the CCF entity 23 collects caller information, such as calling number or called number, for a call attempted from a subscriber, thereby master AIP 22-1 and each slave AIP 22-2 of the intelligent network processor 22. -22-n), the corresponding master AIP (22-1) and each slave AIP (22-2-22-n) is one call at a predetermined cycle time interval, as shown in Figure 4 attached In this case, the initial detection point (initialDP) is transmitted to the SCP 21, where the master AIP 22-1 and each slave AIP 22-2 to 22-n use their own identification number. Decision processing time (①) is determined and the call blocking processing is performed. After that, the call blocking processing is performed at a predetermined cycle time, that is, the number of all AIPs is multiplied by the given call blocking cycle time. If the call is blocked during the period, the blocked call processing method will be performed. Depending on is sent an announcement to the subscriber through the CCF entity (23).

Therefore, SCP 21 can receive one call at the call blocking cycle time interval and perform the corresponding service processing.

Second, the call filtering operation in the intelligent network performs call filtering from the corresponding SCP 21 to the master AIP 22-1 of the intelligent network processor 22 when performing a filtering function for a call requesting a specific service. In this case, the filtered call processing method such as billing, announcement, and the like, the filtering type based on the time interval or the lake, the filtering duration such as the filtering start time and the ending time, and the service, call number, called number, etc. Information about the filtering condition of the AIP 22-1 is transmitted to the corresponding master.

Then, the master AIP 22-1 generates a corresponding indication message, that is, a call filtering message according to the call filtering instruction of the SCP 21, and then generates a call filtering message and a master identification number for notifying that the master is a master. To each slave AIP 22-2 to 22-n, wherein the call filtering message includes information on a call filtering condition, a filtered call processing method, and a filtering type.

At this time, the CCF entity 23 collects caller information, such as calling number or called number, for a call attempted from a subscriber, thereby master AIP 22-1 and each slave AIP 22-2 of the intelligent network processor 22. ~ 22-n), each slave AIP 22-2 ~ 22-n performs call filtering according to the filtering type, and then reports the filtered lake to the master AIP 22-1. In this case, the same call filtering is performed in the corresponding master AIP 22-1, and then, the sum of the filtered lakes and the filtered lakes reported from the slave AIPs 22-2 to 22-n are summed to form the overall filtering lake. Report to SCP (21).

Here, if the corresponding filtering type is a periodic time interval, as shown in FIG. 5, each slave AIP 22-2-22-n performs a call filtering and reaches a predetermined cycle time when the filtered lake is filtered. Is reported to the master AIP 22-1, and if the corresponding filtering type is based on a filtered lake, each slave AIP 22-2 to 22-n reaches a predetermined filtering lake while performing call filtering. If so, the filtering lake is reported to the master AIP 22-1.

Then, the master AIP 22-1 adds the filtered lake from itself and the filtered lake reported from each slave AIP 22-2 through 22-n to reach a predetermined filtering lake or the predetermined filtering period. If time is reached or if the corresponding filtering duration is reached, the aggregated filtering lake will be reported to SCP (21).

At this time, for the call filtered during the corresponding filtering duration, the announcement is sent to the corresponding subscriber through the CCF entity 23 according to the filtered call processing method, and the corresponding CCF entity 23 is instructed to perform billing processing. .
