2 is a schematic diagram of a basic call processing test simulator.

3 is an intelligent network service processing flow chart using a simulator.

The present invention relates to an intelligent network service processing method applying a simulator provided for testing a basic call processing unit by adding an intelligent network service to a service electronic switch.

Existing exchange which provided only general voice service performed all processing inside exchange, but in order to provide intelligent network service, SCP (Service Control Point: hereinafter referred to as SCP) connected to switch with signal link is needed to provide intelligent network service. Various functions should be added and supplemented to the existing exchange, and a basic call processing test simulator is required inside the exchange to test changed basic call processing blocks without interworking with SCP.

Two types of intelligent network services are implemented in the existing TDX-10 switch, and the description of the two kinds of intelligent network services is as follows.

Incoming billing service is a telephone service in which a customer's counseling company charges a caller's own telephone company, rather than charging a caller's telephone call related to sales activities. Companies can receive a variety of additional services, such as registering different phone numbers to receive reservations / inquiries by calling area / time zone / day of the week.

The credit call service is a post-payment method that charges a call charge to a third-party credit billing number rather than to the calling party's number, allowing the caller to talk without cash. Credit call service subscribers can be provided with a variety of additional services, such as limiting calls by call destination / time zone.

In order to provide the above-mentioned service in the electronic switchboard, the SSP No.7 protocol for communication with SCP and the application process for controlling the service and the communication with the SCP must be added.

In order to easily check whether the corrected basic call processing blocks have been modified correctly, a basic call processing test simulator that mimics the functionality of the intelligent network service application process and the functionality of SCP, the database of the intelligent network service, is required.

The simulator receives all signals sent from the basic call processor to the intelligent network service controller, examines the data contents, and sends the signals and data required by the basic call processor. In addition, all cases that may occur in the intelligent network service control unit are reflected in the simulator, so that the basic call processing blocks are correctly processed and checked under all circumstances.

Therefore, by applying the simulator, the present invention can check whether the modified basic call processing blocks correctly handle the intelligent network service without the intelligent network service control, which is a complex application process, and the basic call processing block regardless of the actual development state of the service control. The purpose is to provide an intelligent network service processing method that can easily modify and supplement the necessary information according to the test environment because it has its own DB to test the functions of the network and to test the function of the intelligent network service. .

In order to achieve the above object, the present invention, when the circuit registration control function recognizes the relay line occupancy or the subscriber hook-off, the basic call processing unit allocates a signaling device to the calling party and digitizes the intelligent network service call. The first step of determining the type of service, and if the type of intelligent network service is an incoming billing service, it operates a simulator that processes the incoming billing service to determine whether it is a registered number by being notified of the outgoing signal and calling grade to the basic call processing block. In the second step, if the unregistered incoming billing number is requested, the caller requests the incoming billing number unregistered announcement and terminates the call.If the registered forwarding number is registered, the simulator requests the incoming billing service call to be connected and proceeds with the call. A third step of notifying the simulator when it is finished and ending the number of steps; After that, if the type of the intelligent network service is a credit call service, the simulator 14, which processes the credit call service, comes to life and is notified of the calling number and the calling grade, and requests a credit billing number input, and receives a credit billing number when the credit billing number is input. The fourth step of determining whether the simulator is registered, and the fifth step of determining the suitability of the password by continuing to collect the password by sending an unregistered announcement if the credit number is not registered. And, if the password does not match, broadcast the password mismatch announcement to terminate the call, and if the password is matched, the incoming number is entered, the credit call service call connection is required to connect the call to proceed the call, and when the call is over, the simulator ( 14) and a sixth step of notifying and terminating it.

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

1 is a structural diagram of a service electric switchboard to which the present invention is applied.

In order to distinguish it from the existing electronic switchboard, the service switchboard that performs the intelligent network service function (Access Switching Subsystem 1), which performs distributed call processing functions, will be referred to as ASS. Interconnection Network Subsystem (2) (hereinafter referred to as INS), and Central Control Subsystem (3) (Central Control Subsystem (hereinafter referred to as CCS)) for centralizing functions of operation and maintenance. It consists of four physical subsystems.

ASS (1) is equipped with subscriber and relay line pressure, various signaling devices, time switches to perform most call processing and self-maintenance functions, and has a horizontally distributed structure system. Up to 60 of these ASS (1) subsystems may be implemented throughout the system.

INS (2) is located in the center of the system to connect the ASS (1) with each other or between the ASS (1) and the CSS (3) and the space (Space) switch is located here. In addition, it performs number translation, routing, and space switch connection among call processing functions, and is also responsible for generating and supplying a system clock with a network synchronizer.

CSS (3) is a subsystem that performs the overall maintenance function of the system. It controls system-wide maintenance, testing and measurement, billing and statistics as well as auxiliary storage disks 4 and magnetic tape drivers 5 And operator matching functions.

The intelligent network service control unit 6, which is an application process, is newly added to the service electronic switch in order to implement the intelligent network service function. When a call requesting an intelligent network service occurs, the basic call processing block is notified to the intelligent network service control unit 6 so that the intelligent network service control unit 6 requests the necessary information from the intelligent network service control unit 6 as the basic call processing block. In addition, by using the information provided by the basic call processing block, the intelligent network service control unit 6 controls and manages various processing procedures necessary for providing the intelligent network service.

The intelligent network service control unit 6 is composed of a service processing unit 7 and a protocol processing unit 8. The service processing unit 7 interfaces with basic call processing blocks to manage the intelligent network service. The service electronics exchange checks the eligibility of the intelligent network service call to determine whether to provide the intelligent network service. The database related to the eligibility is stored in the SCP. The protocol processing unit 8 manages communication with the SCP.

2 is a structural diagram of the intelligent network service control unit 6 and the basic call processing test simulator 11 imitating the SCP mentioned in FIG.

The basic call processing test simulator 11 is composed of three types of processes. The main processor 12 that is notified in the basic call processing block of the start of the intelligent network service call and the incoming billing service processing process that controls the incoming billing service call 13 And a credit call service processing process 14 which is in charge of controlling the credit call service call.

When the basic call processing test simulator 11 is first started, only one main processor 12 is alive. When the intelligent network service request is received in the basic call processing block, the main processor 12 determines the intelligent network service type and starts the corresponding intelligent network service processing processes 13 to 14. The incoming billing service processing process 13 has a called billing number database 15 in which each called billing number and the actual called number are configured in a one-to-one correspondence, and thus the actual called number against the called billing number entered by the user (16). ) Can be read.

The incoming billing service processing process 13 notifies the basic call processing unit of the actual called number 16, and the incoming billing number that does not exist in the incoming billing number database 15 is the called billing number non-registered 17 as the basic call processing unit. Notify by.

The credit call service processing process 14 has a credit number database 18, in which each credit number and password 20 are configured in a one-to-one correspondence so that the credit number and password entered by the user exist and match. Can be read. In the credit call service processing process 13, if the credit number and the password 20 exist and have a one-to-one correspondence, the basic call processing unit notifies the basic call processing unit to continue performing the credit call service call.

A credit number that does not exist in the credit number database 18 notifies the default call processor of the credit number unregistered (19), and defaults to a password mismatch (12) if it does not match the corresponding password (20). Notify the call processor.

3 is a flowchart of an intelligent network service using the present inventor, a basic call processing test simulator (hereinafter, referred to as a simulator).

When the circuit matching control recognizes the relay line occupancy or the subscriber hook-off, the basic call processor receives a digit by allocating a signaling device to the calling party. If the received digit is recognized and recognized as an intelligent network service call (101), the main process 12 of the simulator is notified of the intelligent network service call recognition.

The intelligent network service type is determined by the main process 12 of the simulator to save the intelligent network service processing process 13 or 14. Until the intelligent network service call is terminated, the basic call processing blocks interact with the corresponding intelligent network service processing process 13 or 14 to advance the call.

If the type of the intelligent network service is an incoming billing service, the simulator 13 processing the incoming billing service comes up and requests the calling number and the calling class respectively as the basic call processing block (102) and notifies them in the basic call processing block (103). ).

Find the incoming billing number configured as a DB in the simulator 13 to find the actual forwarding number corresponding to the incoming billing number (104). If the incoming billing number does not exist, the incoming billing number unregistered announcement is requested (105) and the call ends.

If the incoming billing number exists, the simulator 13 requests the connection of the incoming billing service call with the actual called number to the basic call processing block (106). In the basic call processing block, the actual called number received from the simulator 13 is translated and the kind of the call is notified to the simulator 13 (107) to route to the called party and connect the call.

Rings and ring-back-tones are sent to the called party and the calling party, respectively. When the called party hooks off (hook-off), the basic call processing block notifies that the intelligent network service call is started (108). At this time, the called party and the caller make a call (109). When the call with the called party and the calling party ends, the basic call processing block notifies the simulator 13 of the call (110). At this time, the call with the incoming billing service processing process 13 is terminated (111).

On the other hand, if the type of intelligent network service is a credit call service, the simulator 14 processing the credit call service comes to life and requests the calling number and the calling grade as the basic call processing block (112), and notifies each of them in the basic call processing block. (113). The simulator 14 requests to connect the tone and DTMFR signaling device to the calling party to the basic call processing block to receive the credit number, password and called number (114), and then requests the credit number input from the simulator (115).

When all the devices are connected and the caller hears a redial, the user first enters the credit number. The basic call processing block receives the crediting number and notifies the simulator 14 (116). The simulator 14 checks whether the credit number is a registered number in the DB (117). If it is not registered, transmits the credit number unregistered announcement (118), terminates the call, and terminates the credit call service processing process (14). do. If the credit number is registered, a confirmation tone is issued to continue collecting the password and the password is required in the simulator (119). If a digit is not input from the user for a predetermined time (second), the password request guide broadcast is transmitted from the simulator (120).

The user enters a password and notifies the simulator 14 of the password in the basic call processing block (121). The simulator 14 checks whether the credit number and the password match (122). If it does not match, the password mismatch announcement is sent 123 to terminate the call, and the credit call service processing process 14 also ends. If the crediting number and password match, the confirmation tone is sent again to request the called number (124). If no digit is input from the user for a predetermined number of seconds, the simulator transmits the called party number request announcement broadcast (125).

The called number entered by the user is notified to the simulator 14 in the basic call processing block (126). Then, the simulator 14 releases the DTMFR signaling device to the general call processing block and requests the credit call service call connection (127). In the basic call processing block, the actual called number received from the simulator 14 is translated and notified to the simulator 14 of the type of call 107, and the call is routed to the called party and connected. Rings and ringback tones are sent to the called party and the calling party, respectively. When the called party hooks off (hook-off), the basic call processing block notifies the simulator 14 that the intelligent network service call is started (108), and the called party and the caller make a call (109). When the call with the called party and the calling party ends, the basic call processing block notifies the simulator 14 of the call (110). At this time, the call is terminated with the credit call service processor 14 (111).

Therefore, the present invention carried out by the above processing procedure has the following application effects.

1) Due to the addition of the intelligent network service, the processing of the basic call processing block should be changed. The changed basic call processing unit can be tested without the protocol processing unit under the AP (application process).

2) It is possible to know whether the processing contents of the call processing block are correct through the CRT screen.

3) The simulator can provide all environments as if they were real.
