Description

How to handle triggering of subscriber or group based intelligent network in exchange system {TRIGGER PROCESSING METHOD OF SUBSCRIBER BASED OR GROUP BASED INTELLIGENT NETWORK IN SWITCHING SYSTEM}

The present invention relates to a trigger processing method in an exchange system, and more particularly, to an intelligent network trigger processing method.

Typically, the switching system performs operations according to incoming and outgoing calls and connection to establish a call for a call between subscribers. As such, the exchange system had to embed all programs capable of providing all information and services for the subscribers in order to perform the processing for forming the call between subscribers. Therefore, when the service is improved or added to the switching system, there is a problem of modifying and replacing the entire switching system, and as a way to improve it, a new type of network called an intelligent network has been created. This intelligent network was further developed with the development of No.7 common line signaling network. As the intelligent network provides various services independently of the switching system, the switching system only determines the call for the intelligent network with respect to the originating call and, in the case of the call to the intelligent network, connects it to the device for processing the intelligent network. It is configured to do so. The most representative of these intelligent network services is a free phone service. Incoming billing services are services in which a group or company is charged for calls received from other subscribers in a way that is generally used by a particular company or organization to join a service provider.

Then, the details of the incoming billing service provided in our country as follows. The phone number of the call forwarding service in Korea consists of a phone number of '080-XXX-XXXX'. When the caller presses only the phone number of '080', the exchange system determines the incoming billing service and connects the call to the intelligent network service system (SCP) according to the incoming billing. This call connection is made through the No.7 common line signal processing method. That is, all subscribers such as callers, ISDN subscribers, public telephones, etc., can receive incoming billing service by dialing '080' first. As such, the services of the intelligent network, in which any subscriber can receive the same services, are collectively referred to as exchange-based services.

On the other hand, when a specific subscriber registers a phone number '080' with another switching service to receive another service, for example, call waiting service, the subscriber performs call waiting service set by the subscriber in the switching system. Connecting to an intelligent network service system for doing so is called subscriber-based service. In addition, when a specific group, for example, a company, etc. dials a specific number, for example, a number '777', it may be configured to be connected to an intelligent network receiving Abbreviated Dialing (ABD) service. As such, a group-based service is connected to an intelligent network service system through a specific number only in a specific group.

There is a growing demand for such subscriber-based or group-based intelligent network services, and there are many services based on subscriber-based or group-based services. However, Korea's exchange system has not yet provided such subscriber-based services and group-based services. Therefore, the current exchange system could not provide subscriber-based or group-based services.

In order to accommodate such intelligent network service, the International Telecommunication Union-Telecommunication standarzation section (hereinafter referred to as ITU-T) proposes various standards. Therefore, the exchange system must be constructed according to these standards to be compatible with other systems. The configuration and operation of the distributed functional plane according to various standards proposed by the ITU-T to accommodate such an intelligent network will be described with reference to FIG. 1.

1 is a block diagram of service logic between distributed functional planes proposed by the ITU-T as a standard. The Call Control Function (CCF) 10 provides call / service processing and control. Call control agent function that manipulates or releases a requested call / service instance from a subscriber station and is included in a specific call or service instance by a request of a service switching function (SSF) 20. CCAF). It also manages the relationship between CCAF entities involved in the call, detects the trigger event, and outputs it to the SSF 20. The SSF 20 is a service exchange function connected to the CCF 10 and provides functions for interaction between the CCF 10 and the service control function (SCF) 30. The SSF 20 then recognizes the service control trigger and extends the logic of the CCF 10 to interact with the SCF 30. It manages the signaling method between the CCF 10 and the SCF 30 and modifies the call / service processing function of the CCF 10 necessary for processing the additional service request under the control of the SCF 30. SCF 30 directs intelligent network call control in the processing of supplementary services or user requests. The SCF 30 also has an intelligent network service logic program, and interacts with other entities to access additional logic or to handle intelligent network call / service instances.

The CCF 10 and the SSF 20 are both located in a switching system, and the SCF 30 corresponds to service logic for performing an intelligent network service. Specialized Resource Function (SRF) 40 directs intelligent network call control in the processing of additional services or user requests. The service data function (SDF) 50 holds customer and network data necessary for the execution of the service, and interacts with the SCF 30 to provide data in real time.

As can be seen from the above, when the telephone subscriber performs the calling operation, the CCF 10 is configured to inquire the SSF 20 according to the intelligent network call. Hereinafter, a process of inquiring from the CCF 10 to the SSF 20 will be described.

2 is a signal flow diagram of an intelligent network call test according to a model recommended by ITU-T when one call originates. As recommended by the ITU-T, when one call is made, the CCF 10 has 11 Detection Points (DPs) for the call that originated the call. It has seven detection points. That is, in case of an outgoing call, the intelligent network call is detected by DP1 to DP11, and in the case of an incoming call, it is detected whether the intelligent network service is provided by DP12 to DP18. Since the DP number is described in detail in the ITU-T's recommendation according to the intelligent network, detailed description thereof will be omitted. In addition, the exchange-based service that currently provides the service detects the intelligent network authorization only in DP2 and DP3. However, in case of the subscriber-based or group-based call, the intelligent network should be able to detect the intelligent network at other detection points except DP2 and DP3. Next, the intelligent network detection will be described with reference to FIG. 2.

CCF 10 is defined to inquire the intelligent network call authorization at DP1 (detection point 1) as recommended by the ITU-T when the call event occurs and the call proceeds. The CCF 10 then inquires whether the call currently being performed is the intelligent network call to the SSF 20 in step 102. Accordingly, the SSF 20 checks the intelligent network call authorization at step 104. If the SSF 20 determines that the call is not an intelligent network call in step 104, the SSF 20 outputs a signal to the CCF 10 to continue the call in step 106. Then, when the CCF 10 receives the signal according to the progress of the call, the CCF 10 continues the operation according to the call. Accordingly, when the DP2 (detection point 2) occurs in step 108, the CCF 10 inquires whether the intelligent network call is sent back to the SSF 20 in step 110. When the inquiry signal is received, the SSF 20 checks the intelligent network call in step 112 and outputs a call progress signal to continue the call to the CCF 10 in step 114 when it is determined that the call is not an intelligent network call. After this process, if the CCF 10 proceeds to DP11 (detection point 11) in step 116, the CCF 10 inquires whether the intelligent network call is requested to the SSF 20 again in step 118. If the inquiry signal of step 118 is received in step S118, the SSF 20 checks whether the call currently in progress is a call to receive the intelligent network service. If it is checked as an intelligent network service call, a trigger signal is output to the SCF 30 in step 122. By checking the call of the subscriber receiving the intelligent network service through this process, the CCF 10 should continuously inquire to the SSF 20 for one call. Accordingly, there is a problem that a situation in which a load may be increased on the SSF 20 and a normal process cannot be performed.

In contrast, the SSF 20 may call the SCF 30 without checking whether the intelligent network service is called or not. This will be described with reference to FIG. 3.

FIG. 3 is a signal flow diagram of an intelligent network call test according to a model recommended by ITU-T when one call proceeds. If a DP1 occurs in step 130 while one call is in progress, the CCF 10 proceeds to step 132 to inquire the SSF 20 of the intelligent network call authorization. The SSF 20 then inquires at step 134 whether it is the call to be received by the SCF 30 for the intelligent network service. Accordingly, the SCF 30 checks whether the current call is an intelligent network service call in step 136, and if it is not a call to receive the intelligent network service, the SCF 30 proceeds to step 133 and outputs a signal to continue the call. Therefore, when receiving the signal, the SSF 20 outputs the signal according to the call progress to the CCF 10 in step 140. Accordingly, the CCF 10 advances the call until the next detection point DP2 is detected. As described above, the call proceeds to DP5 and the SSF 20 is inquired again at step 142 in which DP6 is detected. Accordingly, the SSF 20 outputs an inquiry signal to the SCF 30 in step 146, and the SSF 30 receives the inquiry signal and checks whether the call currently in progress is an intelligent network call in step 148. The SCF 30 outputs a connection signal to the SSF 20 in step 150 if the current call is checked as an intelligent network call in step 148. Therefore, when receiving this, the SSF 20 connects the CCF 10 and the SCF 30 in step 152.

In this way, the exchange system cannot distinguish the intelligent network call, so it must be configured to continuously query the SCF 30 for the current network call. Therefore, not only a lot of load occurs between the CCF 10 and the SSF 10 but also a lot of load occurs between the SSF 20 and the SCF 30. Therefore, there arises a problem that the efficiency of the switching system and the efficiency between the switching system and the intelligent network system is lowered.

Accordingly, an object of the present invention is to provide an effective trigger processing method for subscriber or group based intelligent network service in a switching system.

Another object of the present invention is to provide a method for reducing a load of SSF and processing a trigger in a subscriber or group based intelligent network service in a switching system.

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

4 is a table configuration diagram of a database provided in CCF according to subscriber and group based intelligent network service according to the present invention. Hereinafter, the table configuration and connection relationship of the database provided in the CCF 10 according to the present invention will be described in detail with reference to FIG. 4. First, the configuration of the subscriber data table 200 will be described. The D_LINE_NO 200A stores the line number of a specific subscriber or group registered in the intelligent network service. Hereinafter, all the subscribers or groups will be described as subscribers. The D_SUB_TYPE 200B stores the service type of the subscriber, the D_CG_CHA_CAT 200C stores the category, and the D_TRIGID 200D stores the trigger ID. According to the contents stored in the subscriber data table 200, a corresponding table among the plurality of subscriber trigger tables 210, 220, ... is searched for.

The subscriber trigger table 210 at the top of the subscriber trigger tables 210, 211, ... will be described as an example. The D_TRIGID 210A of the subscriber trigger table 210 is the same as the D_TRIGID 200D of the subscriber data table 200 and finds the subscriber trigger table based on this. The D_TRIG_CNTR 210B stores information on a trigger, and D_TRIGNUM 210C is a trigger number, that is, a reference number of a preliminary trigger table for a preliminary trigger according to the present invention. The trigger refers to a signal that is output from the CCF 10 or the SSF 20 to the SCF 30 to inquire whether a call currently in progress needs to receive intelligent network service. In the present invention, a preliminary trigger is provided. In the following description, the preliminary trigger refers to a signal that inquires whether the SSF 20 should perform the intelligent network service when the call currently in progress in the CCF 10 is first checked as the call to receive the intelligent network service. In addition to the above configuration, the CCF 10 of the switching system according to the present invention stores trigger data in a database.

Next, preliminary trigger tables 220, 221,... Next, the configuration of the preliminary trigger table will be described with reference to the preliminary trigger table 220. The D_TRIGNUM 220A refers to the same as the D_TRIGNUM 210C of the subscriber trigger table 210. Through this, matching between the subscriber trigger table 210 and the preliminary trigger table 220 is performed. In addition, the D_DP 220B stores the sequence number of the DP, and the D_CCAT 220C stores the category according to the call according to the calling category such as the public telephone, the general subscriber telephone, and the ISDN telephone. In addition, D_BNUM 220D is a value for finding a table that stores information according to a called number.

5 is a block diagram of an intelligent network trigger database stored in a CCF according to the present invention. Hereinafter, the configuration and connection relationship of the intelligent network trigger database stored in the CCF 10 according to the present invention will be described in detail with reference to FIG. 5. First, the intelligent network service system (SCF) group table 300 will be described. D_SVC_NAME 300A is a service name of an intelligent network, and D_SVC_KEY 300B is a service key. D_AIN_SSN 300C is usage information of No. 7 signaling, and D_SCFG_NAME 300D is a name of a physical group. The intelligent network service system group table 300 stores a name of a service that a subscriber can receive, information of a key according to the service, and information of No. 7 signaling signal processing. According to this information, it is possible to detect the call authorization to receive the intelligent network service according to the key input by the user, and also refer to the detailed information according to the call to be serviced.

Then, according to the present invention, the CCF 10 looks at the trigger tables 310, 311,..., Which store detailed information according to the trigger in order to send a preliminary trigger to the SSF 20. Since the trigger tables all have the same structure, the trigger table 310 shown at the top will be described as an example. D_TRIGNAME 310A refers to a name for performing a trigger. The D_DP 310B in the trigger table 310 indicates the detection point of the trigger. That is, in the case of a call, the data of the detection point which detects a trigger among DP1-DP11 is stored. The D_SVC_NAME 300A is the same as the service name shown in the intelligent network service system group table 300, and through this, the connection between the intelligent network service system group table 300 and the trigger table can be matched. In addition, D_TRIGNUM (310D) represents the reference number of the trigger. Since the matching is connected to the CCF 10 in this manner, when a specific call is made and proceeds, the preliminary trigger may be output to the SSF 20.

Next, the structure of the preliminary trigger tables 320, 321,..., Matching each trigger table 310, 311,... D_TRIGNUM 320A is data for matching with the trigger table 310A, and D_DP 320B is data that stores the sequence number of the DP. In addition, D_CCAT 320C is a call category of an outgoing category of DP criteria, and D_BNUM 320D is a table for finding a table of called party numbers. This matches the called party table.

Next, the configuration of the called party table 330 matching the preliminary trigger tables 320, 321,... D_BNUM_PTR 330A represents a pointer value of the called party number, and D_BNUM_DGT 330B is a called party digit value input by a user for receiving an intelligent network service. D_EQ_FLAG 330C is flag information for an intelligent network service, and D_TRIGNUM 330D is configured with the same value as D_TRIGNUM 320A in the preliminary trigger table.

6 is a control flowchart of subscriber or group based preliminary trigger processing performed in a CCF according to a preferred embodiment of the present invention. Hereinafter, a control flow during preliminary trigger processing according to the present invention will be described in detail with reference to FIGS. 4 to 6. In addition, the CCF 10 will be described in a state in which a database according to the present invention as shown in FIGS. 4 and 5 is stored.

When a particular subscriber calls, the CCF 10 first examines the subscriber data table 200 and the corresponding subscriber trigger table of FIG. 4 to arm all DPs of the subscriber corresponding to the trigger detection points assigned to the corresponding subscriber. do. Arming here means to reserve in advance so that the detection point can be delivered to the SCF (30). In other words, it checks the authorization to receive the intelligent network service. If the call progresses and the DP1 is detected, the CCF 10 checks whether the DP1 is armed in step 402. That is, detecting whether it is armed at DP1 is a case where a service is allocated to a specific subscriber line D_LINE_NO 200A as shown in FIG. The CCF 10 proceeds to step 404 if the DP1 is armed as a result of the check in step 402, and proceeds to step 410 if it is not armed. If DP1 is armed, the CCF 10 checks call authorization to perform a preliminary trigger in step 404 and proceeds to step 406 to check whether a preliminary trigger should be performed. If it is necessary to perform a trigger, the CCF 10 proceeds to step 408 to perform a preliminary trigger, and performs a mode accordingly. However, if the preliminary trigger should not be performed, the process proceeds to step 410 to check whether DP2 occurs. The CCF 10 proceeds to step 410 when DP2 is detected while the call is in progress, and proceeds to step 424 when DP2 is not detected.

If the occurrence of DP2 is detected in step 410, the CCF 10 proceeds to step 412. The CCF 10 analyzes the telephone number collected during the call in step 412, that is, the telephone number dialed by the subscriber. This analysis refers to checking the dialed number after the subscriber hooks off. The CCF 10 proceeds to step 414 to check whether a digit to process the preliminary trigger is detected. The CCF 10 proceeds to step 416 when the preliminary trigger processing digit is detected in step 414, and proceeds to step 422 when the preliminary trigger processing digit is not detected. In step 416, the CCF 10 checks whether the DP2 called party number is a digit value stored in the called party table 330 shown in FIG. Through this, if the defined digit value is input compared with the digit value defined by the user or the digit value defined by the company that provides each intelligent network service, the called party is checked in DP2. As described above, if the called number is stored in DP2 according to the result of checking whether the called number exists, the CCF 10 proceeds to step 418 to perform a preliminary trigger, and if the called number is not stored (420). Proceed to step). The CCF 10 stores the called party DP information in the subscriber DP information in step 420. This allows the DP to be generated later to find data without specifically checking the digits or the table as shown in FIG. 4 or 5. The CCF 10 proceeds to step 422 to check whether a preliminary trigger should be performed on the call in progress.

Thereafter, the CCF 10 proceeds to step 424 to check whether the DP3 is armed. The CCF 10 proceeds to step 426 when the inspection result DP3 of step 424 is armed, and proceeds to step 432 when it is not armed. When the CCF 10 proceeds to step 426, the CCF 10 checks whether to perform a preliminary trigger based on the information stored in the steps 400 and 420. In step 428, if the check result of step 426 is checked with a call to perform a preliminary trigger, the process proceeds to step 430. When the test is performed with a call that should not perform a preliminary trigger, the process proceeds to step 432. do. The CCF 10 then checks whether the trigger is performed in the DP4 to DP11 in the same manner as in the steps 424 to 430. Through this process, the call currently in progress checks the intelligent network call first, and outputs a trigger signal to the SSF 20 or the SCF 30. This reduces the load on the exchange system without having to contact the SSF 20 every DP.

7 is a signal flowchart when trigger signal output when an intelligent network call is checked in an exchange system according to an embodiment of the present invention. Hereinafter, the signal flow at the time of trigger signal output will be described in detail with reference to FIGS. 4 to 7. The CCF 10 also stores a database according to FIGS. 4 and 5.

If the DPF is detected when a specific call proceeds by the subscriber calling in step 500, the CCF 10 performs the preliminary trigger check on the DP1 through the process as shown in FIG. When it is necessary to perform the preliminary trigger as a result of the check, the process proceeds to step 502 and outputs a preliminary trigger signal to the SSF 20. Then, the SSF 20 checks whether the current call is to be connected to the intelligent network system according to the preliminary trigger information in step 504. If the SSF 20 does not check the call to receive the intelligent network call service in step 504, the SSF 20 outputs a call progress signal for continuing the call to the CCF 10 in step 506. .

Then, the CCF 10 continues the call when receiving the call progress signal. If the DP2 is detected in step 508, the CCF 10 checks whether the call is to receive the intelligent network service by the method described with reference to FIG. If the result of this test is not checked by the intelligent service, the call continues. In operation 510, the intelligent network service is inspected using the same method as described with reference to FIG. 6. In operation 512, the CCF 10 performs the pretrigger test in the same manner as in the DP3 test of FIG. 6. If the intelligent network call is checked in this process, the CCF 10 outputs a preliminary trigger signal to the SSF 20 in step 514. Accordingly, the SSF 20 checks the call authorization to receive the intelligent network service in step 516. The SSF 20 outputs a trigger signal to the SCF 30 in step 518 when it is checked as a call to receive the intelligent network service. The signal output here becomes the trigger signal specified by ITU-T.

Upon receiving the trigger signal, the SCF 30 proceeds to step 520 and checks the intelligent network service call authorization through the information of the currently received call. Accordingly, if it is checked as a call to receive the intelligent network service, the process proceeds to step 522 and outputs a connection signal to the SSF 20. The SSF 20 then connects the CCF 10 and the SCF 30. Therefore, in step 524, the SSF 10 and the SCF 30 are connected. By outputting the trigger signal as described above, the number of inquiries to the SSF 20 is greatly reduced when compared with FIG. 2 according to the related art. In comparison with FIG. 3, the SSF 20 outputs the trigger signal to the SCF 30. The number of times you do it will be greatly reduced. In addition, according to the database of the CCF 10 may be configured not to have the step (504) and 516 to perform the intelligent network call check in the SSF (20).

As described above, it is possible to process a subscriber or group-based intelligent network trigger which is not currently provided by the switching system. In addition, by storing the subscriber-based and group-based database in the CCF of the switching system, there is an advantage that the intelligent network call can be determined without continuously outputting the trigger signal to the SCF or inquiry to the SSF intelligent network.
