The present invention relates to an application process simulation method for identifying an interface between a conventional call processing block and an application process in realizing an information charge storage agent service function in a service exchanger.

The 700 service provided in the conventional general exchange system causes all calls to be routed to the exchange providing the 700 service when a 700 service request is generated from the service user. Therefore, the accumulation of reply occurs frequently, and the charging is performed uniformly in the exchange. According to the various billing functions could not be performed. In addition, since only the exchange-centered service is provided, there are many difficulties in providing a service that satisfies the service provider and the service user due to the lack of various service functions. For this reason, an information fee storage service using the intelligent network has been developed.

The information charge storage service charges the service fee to the information provider after deducting a certain percentage of fees for each service by the public telecommunications operator adding up the call charges on behalf of the information providers and taking charges. It is a return service.

When the service exchanger receives the intelligent network service call from the existing Hochiri block in order to provide the information charge storage agent service, the basic call processing connection unit determines the information charge storage agent service call. In the case of the information fee storage service call, to confirm the eligibility of the call, a query is formed in the information fee storage application process block and transmitted to the service control system (Service Contro1Point), which is a centralized database system. Provide service.

In order to implement the information storage agent service function, the blocks in charge of the existing call processing function are modified in the intelligent network service exchange. To test the modified call processing blocks, the function of the PR AP is because the Premium Rate App1ication Process (hereinafter referred to as PR AP) controlling the intelligent network service call directly interfaces with the existing call processing block. We need a PR AP simulator that mimics.

Accordingly, the present invention receives all signals sent to the PR AP simulator for each test item from the existing call processing blocks of the TDX-10 SSP, and displays the variables and variable values included in each signal on the CRT screen, and each variable. It is an object of the present invention to provide a PR AP simulation method for testing call processing blocks while confirming that they are correctly received by the PR AP simulator.

In order to achieve the above object, the present invention, the existing call processing block modified by implementing the information charge storage agent service function; And a PR AP application simulator having a main process and a sub-process that directly interface with an existing call processing block, to test the information exchange receiving service call of the TDX-10 SSP. An application process simulation method, the main process comprising: a first step of determining whether fixed data and variable data are set, and the simulator waiting for receiving an intelligent network service request; The main process is a second step of determining the intelligent network service to execute the sub-process for processing the service; The sub-process may include a third step of analyzing and processing an available state of a subsystem; The sub-process may include a fourth step of determining and processing whether the information charge storage agency service is eligible; And the sub-process includes a fifth step of analyzing and processing the incoming state.

2 is a schematic diagram of a PR AP simulator, which implements a service fee storage service function, and the information fee storage application directly interfacing with the modified existing call processing block 50 and the existing call processing block. The structure of the process (PR AP) simulator 51 is shown. A main process 52 for receiving an initial signal 54 from an existing call processing block, setting various conditions in connection with a test, and determining an intelligent network service to execute a subprocess capable of processing the service. ) Is composed of a subprocess 53 which performs an information service charge processing service process while exchanging a normal signal 55 directly with an existing call processing block. It transmits and receives signals and tests the test items (1-n) to check whether the existing call processing block normally handles the signal and performs the processing of the information storage service.

3 is a process flow diagram of a simulation method that differs from a PR AP simulator call processing flow.

The PR AP simulator can be divided into fixed data and variable data for the existing call processing block test. The PR AP simulator main process (70) determines whether the test is due to the fixed data (71) to determine whether the variable data test if not the fixed data test (72). If the variable data test is not a variable data test, the test is terminated (73). In the case of a variable data test, a message waiting time is input (74) and a test item is input (75). After receiving the data, the PR AP simulator converts the input data into a local variable (75), and then the PR AP simulator enters a waiting state for receiving an intelligent network service request (79).

On the other hand, if it is determined that the fixed data test is determined in the fixed data test of the PR AP simulator (71), after collecting initial data (77) and converting the collected data into local variables (78), the PR AP simulator requests the intelligent network service. It enters a reception waiting state (79).

The main process of the PR AP simulator, which receives the intelligent network service request from the external TKC unit (80) (80), compares (81) the service data received from the external TKC unit with the initial data given to the PR AP simulator (81). If not, the external TKC unit requests recording guidance / tone transmission of a normal processing impossible notification (82), and enters an intelligent network service request reception waiting state (79). If the service data and the initial data coincide, the PR AP simulator main process executes the sub process for processing the information storage service (83), and the information storage service processing process is performed between the existing call processing block and the PR AP simulator sub process. do.

The sub process of the PR AP simulator analyzes the subsystem unavailability state (84), requests an external TKC unit to record the announcement / tone transmission of the normal processing unavailability (85), and terminates the sub process (86). In step 79, the PR AP simulator enters a wait state for receiving an intelligent network service request. If the subsystem is in an available state, it sends a calling number and calling grade request to an external TKC portion (87) and receives a calling number and calling grade notification from an external TKC portion (88).

Upon receiving the calling number and calling grade, the sub-process of the PR AP simulator determines the eligibility for the information charge storage service (89), and in the case of abnormal processing, requests recording guidance / tone transmission of a normal processing impossible notification to an external TKC unit. After (90), the sub process ends (91) and the PR AP simulator enters (79) the wait state for receiving the intelligent network service request. In the case of the normal processing, the external TKC unit requests the information charge storage agency editing type announcement broadcast transmission (92) and enters a message reception waiting state. The sub-process of the PR AP simulator that receives the information charge storage service execution status (OK) notification 93 from an external TKC unit is requested to release a DTMFR (Dial Tone Multi-Frequency Receiver) to the external TKC unit 94 and information. The external TKC unit transmits the number translation request to the number translation processing unit (hereinafter referred to as NTR) using the actual called number received from the subprocess. The NTR performs number translation, and the sub-process of the PR AP simulator receives the result of number translation of the NTR as a call type notification from the NTR (96). The secondary process of the PR AP simulator receives a novelty status notification from an external TKC unit (97), analyzes the incoming state (98) and requests recording guidance / tone transmission of a normal processing impossible notification to an external TKC unit if the incoming call cost is not available. After that (99) terminates the process (100) and PR PR simulator enters the intelligent network service request reception state (79). In the case of an available call, after receiving an information charge storage agent service call connection notification from an external TKC unit (101), the call is connected to the called party and becomes in a busy state (102). In order to confirm transmission and reception of existing call processing blocks and signals when performing all test items, the sub-process of the PR AP simulator displays the received call / incoming information on the CRT screen. In the busy state 102, the subprocess of the PR AP simulator receiving the information charge storage inbound service call release notification from the external TKC unit 103 performs the call termination process and then terminates the subprocess (104). A service request reception state is entered (79).

Therefore, in the present invention as described above, the information required for transmitting and receiving signals with the existing call processing block is displayed on the cathode ray tube (CRT) screen, and the specific signal of the call processing block is tested to check the call processing state of the information charge storage agent service. For the function test and verification of the call processing block, the function can be checked by using the simulator before interworking with the application process, and the reliability of the service can be secured by deriving and solving problems and functional errors that may be found during interworking. It has an effect.
