The detailed functions of each software function block that performs the protocol processing unit 10 and the service processing unit 11 are as follows.

The Free Phone Operation Execution Execution Unit 14 (hereinafter referred to as FPOE) is a block for performing an operation processing procedure, and an access function with the incoming billing service control unit 22 of the service processing unit 11, an application processor, and the like. Performs basic encoding and decoding of parameters of the component (protocol data unit), operation class and timer value display function with reference to operation related function, indication number and dialog number management, operation / error definition. Then, the receiving charge dialog performing unit 15 performs a function of generating a dialog processing request for component transmission and an indication of service quality and performs a connection function with the component processing unit 16. Here, the operation refers to an operation unit performed by the counterpart application service unit of the request from the incoming billing application service unit 12 that is the user of the question-and-answer function application unit 24.

The dialog execution unit 12 (hereinafter referred to as FPDO) is a block for performing an operation procedure with a dialog related to the transmission and reception of a component by interaction with the FPOE 14. Here, the dialog refers to a correspondence established between two question-and-answer function users to exchange components.

It performs a function of notifying the FPOE 14 of the dialog operation function, the dialog type and the component received by the instruction of the FPOE 14, and matching with the dialog processing unit 17.

When the dialog processing unit 17 (hereinafter referred to as DHA) receives a dialog processing primitive from the FPOE 15, the dialog processing unit 17 receives a component corresponding to the received dialog from the processing unit 16 and reconstructs it to create user data. Transfer to the question and answer processing unit 18. Here, primitive refers to a method of expressing an interface between two adjacent layers, and the above-mentioned parameter is an information element carried in a primitive or a message. In addition, when receiving the primitive from the question and answer processing unit 18, it notifies the FPDO 15, and the corresponding component is transmitted to the component processing unit 16.

When the component processing unit 16 receives a component processing primitive from the FPOE 14, the component processing unit 16 combines the corresponding components and delivers them to the DHA 17, and the process proceeds to the processing state by grade of the received operation. When the component is received from the DHA 17 after the standby state, the Syntax error or the like is checked to inform the FPOE 14 of the result.

When the response processing unit 18 (Transaction HAndling Block; hereinafter referred to as THA) receives a transaction processing primitive from the DHA 17, it generates a corresponding message processing function application unit 24 message to connect the signal of the basic call processing unit 4. Send to the control block. When the primitive is received from the signal connection control block, the message processing function application unit 24 extracts the message, checks the syntax error and transaction status, and transfers the primitive to the DHA 17.

The basic call processing interface 19 (hereinafter referred to as BCPI) is an intelligent network service control unit 5 and a basic call processing unit 4 so as to easily change service calls and add new services. It is a block dedicated to the interconnection function with. It plays a role of mutually communicating information such as cognitive notification of intelligent network service call, service call connection and restoration request, additional information collection request, announcement broadcasting connection request, and billing performance request.

The incoming call service control unit 22 (hereinafter referred to as FPSC) recognizes and notifies the incoming call service request from the basic call processing unit 4 and confirms whether the service can be provided to the service management unit 23, and then the FPOE ( 14), call forwarding service request operation for service request is required. When receiving confirmation of the operation from the FPOE 14, this data is analyzed and the service can be provided. When receiving the confirmation of the operation from the basic call processing unit 4, this data is analyzed and the basic call processing unit is provided. (4) request the call route configuration, and when the call is connected to provide the service to the incoming billing service management unit 23 to perform the billing function using the billing information received from the FPOE (14). When the service is not available, the announcement or tone is sent to the service user.

3 is an overall flowchart of the present invention. The present invention will be described in detail with reference to the drawings.

When the relay line occupancy / subscriber hook off is recognized in the rotation matching control block of the basic call processing section 4, the basic call processing section 4 requests the rotation matching control block to allocate the R2 / DTMER signal device. 32).

When the signaling device control block receives the digits from the source switching center / sending party (33), it transfers the collected digits to the traffic control block of the basic call processing section (4). The traffic control block requests number translation from the INS 2 and receives the result (34). If the translation result is a general call, it interacts with related functions to form a call (35), and if it is an intelligent network service, BCPI (19) notifies the intelligent network service call recognition. When the BCPI 19 block receives an acknowledgment of the intelligent network service from the traffic control block of the basic call processor 4, it determines the corresponding intelligent network service using a trigger table (36). If the incoming billing service is determined, the FPSC 22 is requested to perform the corresponding service, and if it is determined as another intelligent network service, the corresponding intelligent network service is performed (37). The FPSC (22) block asks the FPSM (23) whether the service is provided for the received billing number (38) and if it is not possible, the FPSC (22) blocks the broadcast or tone to the calling subscriber (39). On) (40) ends. If the service is available, the FPSC 22 collects outgoing subscriber numbers (41, 42) to perform the incoming billing service.

Prior to connecting the incoming billing service call, the relevant database stored in the central database center in the common line signaling network is applied to the common line signaling method No.7 protocol in order to obtain the qualification check and the actual routing number of the incoming billing number received at this point. After remote inquiry, use appropriate call processing according to inquiry result. To this end, the FPSC 22 forwards the primitive requesting information to the FPOE 14 using the collected information to the service control system (SCP) in the common line signaling network and receives the result from the service control system (SCP). When the FPSC 22 generates a primitive requesting information from the service control system (SCP), the FPOE 14 receives this primitive to generate a command providing operation (44), and the operation and assignment that occurred. Basically encoding the indication parameter terms using the dial-numbers, etc., to generate a component (operation instruction), which is a protocol data unit between the application service units 12 and 13 and the question and answer function application unit 24, and generates a component processing primitive. Pass to CHA (16). Receiving a component processing preamble, the CHA 16 stores the received components. The EPOE 14 instructs the CHADO to perform a dialog start operating procedure when the component delivery is completed. Upon receiving this, the FPDO 15 block forms a dialog and encodes the information necessary to actually process the start of the dialog so that, when it occurs, the component generated by the application service unit is transmitted to the counterpart application service unit of the destination node. The service is then sent to the DHA 17 to request service (45). Receiving this, the DHA 17 block requests the CHA 16 to deliver the component associated with the dialog. The CHA 16 then activates the Class 1 Invoke State upon delivery of the Class 1 component that was resisting (46).

Here, the class 1 invoke state refers to the first class of the operation class, the operation class is the number of the operation is classified and displayed according to the method of reporting the performance result, and the class 1 refers to the operation class for reporting success or failure.

The DHA 17 receives the components related to the dialog, and then, for this component, the lower layer forms a transaction and processes the transaction start to deliver components generated in the generator component part to the partner component part of the destination node. The code is transmitted to the THA 18 as a primitive requesting the start of a transaction, and the service is requested (47). Receiving this primitive, THA 18 encodes the components into one TCAP message (start), and then the lower-level message processing function application unit 24 (TCAP) message is encoded. Encode the necessary information to be transmitted to the transaction part of the destination service control system (SCP) in a connectionless manner and transmit it to the signal connection control block of the basic call processing part 4 as a primitive block (48). The processing function application section 24 waits to receive the message (49). The signaling connection control block and the message delivery control block in the basic call processing unit 4 supporting the network service layer are a destination transaction for a message originating function application unit 24 message in which a transaction layer layer that is a user of the network service layer is generated. Perform the function passed to the sublayer without error.

When the signaling connection control block passes the primitive to the THA 18 (50), the THA 18 extracts the message processing function application 24 message from the primitive (end) and sends the transaction end to the DHA 17. (51). The DHA 17 delivers the dialog termination as a primitive to the FPDO 15 in the same manner as the transaction processing, and delivers the received components to the CHA 16 and terminates the transaction (52). The FPDO 15 having received the dialog termination primitive informs the FPOE 14 that the component has been received and that the dialog termination request has been received (53). The FPOE 14 prepares for component reception. The CHA 16 delivers the received component to the FPOE 14 (54), where the component combination must have a success result report or a failure result report. These components release the Invoke State which was activated in response to the self-instruction. The FPOE 14 waiting for the component decodes a return result parameter term indicating successful execution if it receives a success result primitive, and a return error parameter term indicating operation failure if it receives a failure result primitive (55). The received response is notified to the FPSC 22 by a primitive (56). Upon receiving the result, the FPSC 22 analyzes the result (57), and when the service cannot be provided, requests the basic call processor (4) to send the corresponding recording guide or tone to the calling party to send the recording guide or tone. The call to the basic call processing unit 4 sends out a recording guide or tone (58), and detects the hook on of the calling party (Hook On) and ends the processing (59).

The FPSC 22 requests routing to the incoming number received from the INS 2 (60), and the INS 2 constructs a call path (61). If the called party is a relay line, it requests the signal device control block of the ASS (1) on which the called party is mounted an R2 MFC signaling device assignment (62) to perform inter-station signaling, and if it is a subscriber, to connect the ring to the circuit matching control block. (63). When the hook off from the called party is recognized by the line matching control block of the basic call processing unit 4 (64) and notified to the FPCS 22, the CCS 3 is notified of the start of the charging service. 65).

When the hook-on of the calling party is recognized by the line matching control block of the basic call processing unit 4 (66), the CCS 3 is notified of the termination of the incoming billing service charging (67) and the INS 2 is connected to the call. A call is requested (68) and the called party is asked to send a relay line forward request signal.

This completes the processing of the incoming billing service call, an intelligent network service.

4 is an internal flowchart of FPOE 14 processing in the protocol processing unit for the incoming billing application service.

When the FPSC 22 generates an information provision request primitive, the FPOE 14 generates an operation by receiving the information provision primitive (100), which is a component that is a protocol unit between the application service layer and the Q & A function 24. The FPDO 15 is required to establish a logical correspondence with the application service unit of the destination node after encoding the data to the CHA 16 after encoding the data with the CHA 16 (101). For this purpose, the instruction providing operation is encoded into the indicating component, and the component processing request primitive is transmitted to the CHA 16. In addition, the internal information is transmitted to the FPDO 15 as a component delivery start, and the FPDO 15 operates to start a dialog and transmits a component delivered to a lower layer to a relative same layer of the destination node (102). When this procedure is finished, it waits to receive a response from the counterpart node (103). When the internal component reception information is received from the FPDE 15 (104), the partner node recognizes that a response has been generated, waits for the component reception (105), and when receiving a component from the CHA 16, receives a response. Perform the procedure. Upon receiving a success or failure report primitive from the CHA 16 (106), the corresponding operation / error definition is referred to by the dialog number and the indication number of the primitive. The parameter term of the return error component, which is a case, is decoded and the response information is transmitted to the FPSC 22 (107). At the end of this procedure, the FPOE 14 ends the processing.

5 is an internal flowchart of the FPDO 15 processing.

When the FPDO 15 receives the start of component delivery from the FPOE 14 (200), the DHA 17 encodes the dialog number and the destination and source address information necessary for the start of the dialog so that the DHA 17 processes the actual dialog start. The service request is delivered to the service 201. When this procedure is finished, it waits to receive dialog processing of the counterpart node (202). Upon receiving the dialog termination primitive from the DHA 17 (203), the other node recognizes that the dialog has been terminated and transmits the component reception termination internal information to the FPOE 14 to inform that the component has been received.

After this procedure, the FPDO 15 ends the processing.

6 is an internal flowchart of CHA 16 processing.

When the CHA 16 receives the component processing request primitive from the FPOE 14 (300), it stores the component in this primitive (301), and when the DHA 17 sends the internal information, the stored component is stored as internal information. To the DHA 17. Then, because the class 1 indication component has been delivered, the class 1 invoke state is activated (304) for the indicating component. When this procedure is finished, it waits for a component from the partner node (305).

Upon receipt of internal information from the DHA 17 (306), the components contained in this internal information are delivered to the FPOE 14. Since the component combination carried at the end of the dialog contains a result component of encoding the return result, the result component is necessarily transmitted (307). At the end of this procedure, the activated Invoke State is released (308) and all procedures are terminated.

7 is a flowchart of the DHA 17 processing.

Upon receiving the dialog start request primitive from the FPDO 15 (401), the internal information is passed to the CHA 16 to collect the components related to the requested dialog (402), and then the relevant components are converted into internal information from the CHA 16. If received (403), this component is delivered to the THA 18 as a transaction setup request primitive to be delivered to the same layer of the partner node, requesting the transaction unit service (404). When this procedure is finished, it waits to receive transaction processing from the partner node (405). Upon receiving a transaction termination primitive (406), the partner node informs the dialog termination primitive that it has terminated the dialog (407), and then delivers the component loaded on the dialog to the CHA (16) as internal information (408). Exit after this procedure.

8 is an internal flowchart of the THA 18 processing.

Receiving a transaction establishment request primitive from the DHA 17 (500) encodes (starts) a single Q & A message so that the components in this primitive are passed between transactional users (501), which translates the transaction to the destination node. The information is added to the protocol header to be transmitted to the unit, and the unit data message is transmitted to the signal connection control block of the basic call processor 19 (502). When this procedure is finished, it waits for receiving the Q & A function 24 message from the partner node (503). Receiving a transaction termination primitive from the signaling connection control block terminates the transaction (504) and extracts the message processing function application (24) message (505) to identify the associated dialog by the transaction number DHA (17) (506). At the end of this procedure, the THA 18 treatment procedure is terminated.

The present invention, which consists of the above-mentioned steps, provides an intelligent network service in an existing electronic switchboard, and charges a telephone call to a caller in connection with a sales activity in a company where a lot of customer telephone consultations are charged to the caller. There is an application effect that can provide a variety of additional services, such as to provide a telephone service, and to register by different phone numbers received reservations / inquiries by calling region / time zone / day.
