Figure 3 is a flow chart of information charge storage service call according to the present invention.

The present invention relates to a method for controlling an information charge storage agency service call of a service exchange.

In case of 700 service provided by the existing general exchange, all call is routed to the exchange that provides 700 service when 700 service request is generated from the service user. Therefore, circuit congestion occurs frequently and the billing is performed uniformly in the exchange. Various charging functions could not be performed according to the grade. In addition, since only the exchange-centered subs were provided, it was difficult to provide a service satisfying the service provider and the service user due to the lack of various functions of the service. For this reason, it was required to develop a forwarding charge service for information charges.In order to perform an information charge storage service using an electronic exchange, it was triggered by an application processor after recognizing the information charge storage service call in the existing call processing process. A function is required to control the call so that the receiving agent service call can continue.

As the demand level of the communication user increases, the intelligent network that emerges to satisfy this demand is a service switching system (SSP) and a centralized database system that recognizes the intelligent network service call and performs a service exchange function. It is a network based on SCP: Service Control Point) and uses common line signaling method No.7 protocol. The intelligent network has an easy structure for the introduction of new services, and the types of intelligent network services are increasing. Therefore, in order to provide various intelligent network services, the exchange function for intelligent network service calls is provided to all electronic exchanges that process existing general calls. Necessary when adding SSP function in charge.

An object of the present invention devised to meet the above-mentioned requirements is to provide a method for communicating with a service control system by adding an intelligent network service exchange function to an electronic switching system and controlling a service charge storage service call.

In order to achieve the above object, the present invention provides three types of AAS (Access Switching System), Interconnection Network Subsystem (INS) that performs centralized call processing, and Central Control Sybsystem (CCS), which is responsible for centralizing operation and maintenance. In a storage agent service call control method, the information is applied to an electronic switching system that has a physical sub-system and performs a distributed call processing function, and receives information charge storage service call and collects necessary information from the basic call processing block. A first step of determining whether or not a service can be provided and sending a query for a qualification check and a number translation request to a service control system (SCP) and waiting for a result; A second step of receiving and processing primitives sent from the SCP; A third step in which the service user abandons the call before the information charge storage agency service call is connected and receives the information charge storage service call abnormal path from the basic call processing block; A fourth step of calculating the billing details upon receiving the final primitive and requesting the service user to transmit the announcement for the paid service announcement, and confirming the intention of using the service to connect the call; And a fifth step of performing a call release service after the call charge.

Information charge storage service is a service that allows service users to connect to an information provider through an intelligent network to use the information and pay the information fee in return. It is a service that charges and collects the service to the service user and returns it to the information provider except for a part of the information fee in exchange for providing the network and charging and retrieving the information fee according to the charging calculation method.

In order to perform the information charge storage service call, it is possible to collect the necessary information by recognizing the request from the basic call processing block to the information charge storage service, and provide the service to the service control system through the common line signal network using the collected information. Send a query to check whether In response to the actual call number and the billing information for the information charges, the service broadcasts the service user to the service user about the information charges and confirms the intention to use the service from the service provider, and then connects the call with the information provider. We need to proceed with the information fee agency Sibisho scenario.

To this end, to define the service charge status model of information service, and to perform the role of a gateway to the intelligent network, the application system for question-and-answer function of the No.7 protocol corresponding to the top layer is the OSI (Open System Interconnection) reference model. Transaction Capabilities Application Part As a user, we present a method of handling the primitives of the protocol defined in the application service element (ASE).

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

FIG. 1 is a schematic diagram of an electronic switching SSP configured by adding an intelligent network service control subsystem (ISCS), which is a new sub-system, to provide an electronic switching system.

The electronic switchboard is an Access Switching System (ASS) that performs distributed call processing, an Interconnection Network Subsystem (INS) that performs centralized call processing, and a Central Control Subsystem (CCS) that centralizes operation and maintenance. It consists of three physical subsystems.

ASS has pressurizer and repeater line matching, various signaling devices, time switch, etc. to perform most call processing functions and self-maintenance functions, and has a horizontally distributed structure system. Up to 60 of these ASSs can be deployed throughout the system.

The INS is located at the center of the system and performs the function of connecting ASS to each other or between ASS and CCS, and the space switch is located here. In addition, it performs number translation, routing, and space switch connection functions among the call processing functions, and is also responsible for generating and supplying a system clock by having a network synchronizer device.

CCS is a subsystem that performs the overall operation and management of the system. It controls the steam cool test, maintenance, measurement and statistics, billing, as well as the auxiliary storage disks and magnetic tape (MT) drivers. Provide operator matching function.

ISCS is newly added to ASS to process intelligent network service, and ISCS is composed of service processor that manages intelligent network service and protocol processor that manages communication with SCP. The service processor includes an application process that handles intelligent network service call processing and an application service element that supports a function of a specific intelligent network service.

Information charge storage service is a service that is further developed after the incoming billing service and credit call service developed in the electronic switchboard SSP. The PRS (PRemium Service Control) and PRSM ( Added blocks of PRmium Service Managment (PREM), PRIE (PRemiun Service Operation Execution), and PRDO (PRemium Service Dialogue Operation), and changes the basic call processing interface (BCPI) block that is responsible for matching the basic call processing unit with the intelligent network service call processing unit. This is necessary. In addition, FPSC (Free Phone Service Control), FPSM (Free Phone Service Management), FPOE (Free Phone Operation Execution), FPDO (Free Phone Dialogueue Operation), CCSC (Credit Call Service Control), Credit Call Service Management (CCSM), Credit Call Operation Execution (CCOE), and Credit Call Dialogue Operation (CCDO) blocks.

The protocol processing unit is composed of a question and answer processing function application unit, a signaling connection control part (SCCP) and a message transfer part (MTP: massage transfer part), and the block corresponding to the application part is the CHA (Compoent HAndling). ), Dialogue HAndling (DHA), and Transaction Handling (THA) blocks.

In the electronic switching center SSP, the information charge receiving service is performed by the interoperation of the above-mentioned blocks, and receives an intelligent network service call from the basic call processing block. The received call is assigned to the service charge information service and the query is sent to the SCP and processed in each block to proceed with the call according to the result as follows.

The BCPI block is a block that performs the interconnection function between the basic call processing unit and the intelligent network service call processing unit. When receiving the intelligent network service from the basic call processing unit, the BCPI block analyzes which intelligent network service call is received. The relevant information is transmitted to the PRSC block of the service processor.

The PRSC block is an application process that performs the information storage service. When the request is received from the BCPI block, the PRSC block collects additional information such as the called number for the service call control and sends the query to the SCP. Proceed with the service call according to And when receiving a call blocking request from SCP, the function to block the call according to the call blocking information, local identification number assignment and return function to identify a specific intelligent network service call, broadcast transmission request function, call blocking information request from the operator It performs the function of transmitting information, performing call blocking when receiving a call blocking request from SCP, notifying the operator, and calling statistical primitives when an event occurs to collect statistics according to the corresponding event.

The PRSM block collects and manages various data related to the information storage agent service, and interacts with the PRSC, billing, measurement / statistical, and test / fault detection function blocks to perform various functions according to the information storage agent service provision.

The PROE block is a block that executes the operation processing procedure. The basic encoding and decoding function of the parameter of the component by referring to the PRSC block and connection function, operation association, indication and dialog number management, and operation / error definition of the information storage agent service processing unit. It performs the function, class of operation and display of timer value. Then, the PRDO block, which is the information charge storage service dialog management unit, requests dialog processing for component transmission and performs a connection function with the CHA block, which is a component processing unit.

The PRDO block performs the dialog operation procedure related to component transmission and reception by interacting with the PROE block, and informs the dialog operation function, dialog type and component reception in the PROE block by the instruction of the PROE block, and the DHA block and Perform the matching function.

When the DHA block receives the dialog processing primitive from the PRDO, the DHA block receives the component corresponding to the received dialog from the CHA block, reconstructs it, creates user data, forms a transaction processing primitive, and delivers the THA block. In addition, when a primitive is received from the THA block, it notifies the PRDO block and delivers the corresponding component to the CHA block.

When the CHA block receives the component processing primitive from the PROE block, it combines the corresponding components and delivers them to the DHA block.After receiving the component from the DHA block after transitioning to the processing status of the received operation, the CHA block checks the syntax error for the result. It performs the function of passing to the block.

When the THA block receives the transaction processing primitive from the DHA block, the THA block reconstructs the received user data to create a TCAP message and sends it to the signaling connection controller.When the THA block receives the primitive from the signaling connection controller, the THA block extracts a TCAP message from the syntax error and transaction. It checks the status and passes the primitives to the DHA.

2 is a structural diagram of an information charge storage agent service application process for providing an information charge storage agent service.

An information service agency service application processor consists of three processes and seven procedures. The process starts with PRSC, and the procedure starts with pd-SSP-PR.

PRSC＿main

The BCPI block that is notified of the intelligent network service call from the basic call processing block determines which intelligent network service call by using a trigger table, and drives the PRSC-main process of the PRSC block if it is an information charge storage service call. The PRSC-main process is a permanent process for controlling and managing information storage service calls.The PROE block and the Promise Song, the ASE layer of the No.7 protocol, are used to send queries to the SCP and receive the results. Request and manage the process ID of the PROE block so that it can be received. If any process among ASE, TCAP, and SCCP goes down and restarts while the service charges are in progress, the information is received from the higher protocol of the down process and assigned a new process ID to communicate with the process ID. Send and receive the signal. When an information fee storage service call occurs, the information is received from BCPI and an ORSC-actual process is created to process the service call. It manages the status of sub service team and signaling point, and if the status of service system and signaling point is not available, it recognizes the status of this process and blocks the call without proceeding when information storage agent service call occurs. .

.PRSC＿actual

The PRSC_actual process is generated in units of calls when the PRSC_main process determines that the information fee storage agent service call is terminated, and is terminated when the information charge storage agent service call is abnormally terminated or a call path is normally formed. When creating a PRSC＿actual process, it receives the information provider number from the PRSC 파라 main as a parameter to determine whether this number is available for service, and if the result requires call blocking, it indicates the call blocking according to the call blocking information. If possible, collect the calling number and calling grade, the information required to send an inquiry to SCP. After the query is formed to require translation and qualification of the number into the SCP, a PR-PROVIDE req primitive is generated and sent to the PROE block. Receives the result of the qualification check and the number translation of the query from the SCP through the PROE block with the corresponding primitive. Receivable primitives include the rejection (PR-PEJECT ind) primitive call cancellation (PR-CANCEL ind) primitive, call blocking (PR-GAP ind) primitive, call state notification request (PR-NOTIFY ind) primitive, and call control information (PR). -PROVIDE conf) primitives. These primitives can be received singly or continuously and control the call according to the information provided by each primitive. When the final primitive is received from the SCP, the call processing is performed using the call processing information contained in the PR-PROVIDE conf primitive. Extracts billing information such as information grade, PPM code and discount rate from information received from SCP and transfers it to the CDG (Chagrging Date Generation) block, a billing block, to receive billing information for the rate per hour (30 seconds) .

In order to notify the service user of the paid service, the fee for using the information per 30 seconds of the information providing service is transmitted in an editable guide broadcast and the intention to use the service is confirmed. After confirming the intention to use the service from the service user, in order to connect the service call with the information provider, the actual caller number received from the SCP is transmitted to the basic call processing block and the connection request for the transmission fee storage service call is requested. In the process of connecting the information charge storage service call, notification of the call type from the basic call processing block, such as the home call, incoming call, outgoing call, and relay call, incoming call status such as incoming call, non-answered call, and missed call, and In this case, the caller receives a notification of the service charge connection service call and connects the call. After the completion of the call, if the normal call release notification is received from the basic call processing block, the charging information is sent to the CDG block to perform the charging according to the talk time and the call is terminated.

In addition, for operation and management of the information storage agent service call, when receiving the information service charge service call notification from the basic call processing block or when a service request occurs for the call being blocked, the PROE block and the event for the primitive transmission / reception are processed. The statistics library of the Premium Service Management (PRSM) block is called.

.pd＿SSP＿PR＿LID＿ini

Initializes the LID (Local IDentifier) management table for the service charge storage service call and is operated by the PRSC_main process.

.pd＿SSP＿PR＿LID＿insert

In the PRSC 받는 actual process, the LID is assigned when the PR-PROVIDE req primitive is generated for the eligibility check and translation of the service charge. The LID table is assigned a number from 0 to 499, which is a unique number for each information charge agency service number.

.pd＿SSP＿LIDtbl＿delete

When the final primitive is received from the PROE block in the PRSC_actual process, the LID of the corresponding information storage agent service call is deleted.

.pd＿SSP＿PR＿ACG

Performs a function of determining whether a service call is blocked according to the contents of a database when receiving a service charge storage service call. In this case, one or more ACGs may be applied to a specific call. The database is searched to determine whether the call is blocked by applying call blocking information in order of length of the control number. At this time, a series of calls having a code that is subject to call blocking control in a received call are blocked until the blocking period ends. The first call that arrives after the end of the interception cycle is instructed to be processed normally, and the call interception control is instructed for a call arriving from the next time by changing and registering the start of the interception cycle immediately.

.pd＿SSP＿PR＿CGAP＿insert

Called when the PR-GAP ind primitive is received from SCP in the PRSC＿actual process, and the control number, control number digit number, blocking time, blocking cycle, blocking cycle start, blocking win by extracting the contents of the PR-GAP ind primitive delivered as parameters. Stores information about the data in the database.

.PRSC＿ACG＿delete

After entering the call blocking function into the database, when the blocking time elapses, the call blocking information is deleted by operating the timer from CROS (Concurrent Realtime Operating System).

.pd＿SSP＿PR＿GapInfo＿disply

When an operator receives an output request for information blocking service call blocking information stored in the database, it is called by the PRSCEmain process and delivers the call blocking information stored in the database. In this case, the blocking information stored in the database is sorted and transmitted by the cause of blocking, and the call blocking information remains in the database even after the blocking time has elapsed due to the restart of the process of handling the service charge service service call and the malfunction of the PRSC＿ACG＿delete process. It also includes a function to tell whether or not.

.pd＿SSP＿PR＿GapInfo＿delete

When the operator receives a request to delete the information charge storage service call blocking information stored in the database, the operator deletes the related information from the database using the information received from the operator and delivers the result.

3 is a flow chart of information charge storage counter service call according to the present invention.

Receiving an information charge storage service call from the BCPI block (1), it is analyzed whether the service can be provided using the call blocking information stored in the database (2). If the analysis result (3) the call blocking request occurs and the service can not be provided, request (4) to send the announcement of the cause to the service user and terminate the call. If the analysis result (3) is able to provide the service, it requests (5) the basic call processing block for the calling number and calling grade required to send an inquiry to the SCP (6). Process transfer (7) the primitive requesting qualified screening and translation of the number to the SCP and listening to the result notification (8). Receiving a call blocking primitive from the SCP (9) informs the operator that a call blocking request has occurred (10) and stores the call blocking information in the database (11). It is determined whether this primitive is the final primitive sent by the SCP (12) and waits for the result until it receives the final primitive if it is not the final primitive. Upon receiving the event notification request primitive from the SCP (13), an event notification primitive is generated (14) to notify the SCP of the result when an event occurs according to the call progress state.

It is determined whether this primitive is the final primitive sent by the SCP (12) and waits for the result until it receives the final primitive if it is not the final primitive. Receiving an information provision primitive notifying the result of the eligibility inspection and number translation from the SCP (15), the accounting information necessary for calculating the billing history for the information provision service is extracted (16). It is determined whether this primitive is the final primitive sent by the SCP (12) and waits for the result until it receives the final primitive if it is not the final primitive. Receiving a reject primitive from the SCP (17) informs the operator (18), the lower protocol (ASE) 19, and the service user 20 that a protocol error has occurred and ends the call. Receiving a call cancel primitive 21 from the SCP requests the service user to send an announcement to the basic call processing block in order to convey that the service cannot be provided (22) and ends the call. When the service user cancels the call while receiving the final primitive from the SCP and receives the information charge storage service call abnormal notification from the basic call processing block (23), the call cancellation free for the end of the operation is performed in the information charge storage service ASE layer. Transmit 24 to terminate the call.

If a primitive requesting call status notification is received from the SCP (25), the event notification primitive is forwarded (26). If the final primitive is received from the SCP (12), the result of the qualification check and the number translation received from the SCP is analyzed (27), and if the eligibility test fails, it is determined by receiving (28) whether the primitive requesting the call status notification is received from the SCP. If so, the result is delivered to the event notification primitive (29), and the call is terminated after the request for transmission of the announcement broadcast to the basic call processing block (30) to notify the service user that the service cannot be provided due to an error in the qualified test result. do. If no primitive requesting the call status notification is received (29), then the event notification primitive is not delivered. If the eligibility test and the number result is successful (27), the information for calculating the billing history for the information providing service call is transferred to the billing block (31), and the billing information for the hourly (30 seconds) bill amount is received ( 32).

The service user is notified of the paid service and is requested to transmit a guide broadcast that delivers the charge amount per hour (30 seconds) of the information providing service (33), and confirms the intention of use (34) from the service user. The actual incoming number received as a result of number translation from the SCP is transferred to the basic call processing block to request the connection of the information charge storage service call (35). Intelligent network service call type 36 and incoming call notification are received 37 from the basic call processing block. If the call connection result 38 is abnormal, when the primitive requesting the call status notification is received (39), the event notification primitive is delivered (40) and the broadcast request for the cause of the failure is transmitted to the basic call processing block ( 41) and the call ends. If the call connection is normally established (38) after receiving the information fee storage agency service call connection is received from the service user information fee storage agency service call release notification (44) generates the charging information according to the call time (45) billing processing block End the call after forwarding (46). At this time, if the primitive requesting the call status notification is received from the SCP (47), the premise notification primitive notifying the normal release of the information charge storage service call is delivered (48) and the call is terminated.

According to the present invention, when a request for an information fee storage agency service call occurs, when a notification of an intelligent network service call occurs in a basic call processing block, a service for providing a service fee storage service can be provided. have.
