The QCAP (9) is divided into component sublayers, traction and sublayers. The component sublayer provides a function for delivering components between specific application service elements, and the transaction sublayer provides a dialog for delivering transaction messages. Provide the function.

When the dialog processing block (DHA) 11 receives the dialog primitive from the dialog execution block of the application service element, it receives a component corresponding to the received dialog from the component processing block (CHA: 10) and forms a transaction primitive with user data. Transfer to the processing block (THA: 12). In addition, upon receiving the transaction primitive from the transaction processing block 12, a dialog primitive is formed and transmitted to the dialog performing blocks 19 and 23 of the application service element, and the component is transmitted to the component processing block 10.

When the component processing block 10 receives the component primitive from the operation execution block of the application service element, the component is encoded and stored for each dialog, and the corresponding component is delivered to the dialog processing block 11 at the request of the dialog processing block. The component is discarded by the dialog termination message of the dialog processing block. In addition, upon receiving the component from the dialog processing block 11, the component is checked for errors, and a component primitive is formed according to the result and the type of the component and transmitted to the operation performing blocks 18 and 22 of the application service element.

When the transaction processing block 12 receives the transaction primitive from the dialog processing block 11, the transaction processing block 12 forms a question processing message and transmits the message to the signal connection control unit. When the transaction processing block 12 receives the question processing message from the signal connection control unit, it checks the error of the message and the result. A transaction primitive is formed according to the type and transmitted to the dialog processing block 11.

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

5 is a flowchart according to the present invention,

A first step of checking whether the number of processor generations is exceeded,

In the first step, when the number of generation excess flags is assigned a transaction number of 0, and the allocation pointer is incremented, the number of allocation printers is set to 0 and the number of process generation counts is set to 1 when the number of main processor generations is exceeded. ,

A third step of checking whether the processor generated number exceeding flag of the first step is not zero (allocation point-recovery pointer) is less than zero;

In the third step, when the number is 0, the allocation pointer for assigning a transaction number is increased by one, and the allocation pointer checks whether the number of main process generations is exceeded, and when the allocation pointers are exceeded, the allocation pointer is zero and the process generation number exceeding flag is set to 1. There are four steps.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5.

In step 45, the dialog processing unit 13 of the question-and-answer function application unit 9 waits for a transaction number assignment request. In step 49, the category over flag and the allocation pointer are set to 0. In step 48, the number of processors is exceeded. Check if the plaque is zero. When 0 in step 48, a transaction number is assigned in step 49, and an allocation pointer is increased by one.

In step 51, it is checked whether the allocation pointer exceeds the number of main processor generations.

The allocation pointer is set to 0 when the number of processors is exceeded and the number of processor generation exceeded flags is set to 1 when the number of processors is exceeded in step (51). The recovery pointer is subtracted from the allocation pointer when the number of processors exceeded flag is not 0. Check if it is big. If it is greater than 0 in step (55), the fault message is processed in step (63), and if it is less than 0, the transaction number is assigned in step (57) and the allocation pointer is increased by 1, and in step 59, the allocation pointer is generated by the main processor. Check if it exceeds. When the allocation pointer exceeds the number of main process generations in step (59), the allocation pointer is set to 0 and the process generation count exceeded flag is 1 in step (61).

That is, the intelligent network service component processing request message is transmitted from the application service element (ASE) 7 of the No. 7 signaling protocol to the question processing function application unit. The Transaction Capabilities Application Part (TCAP) 9 receives the message, classifies the service type by the dialog number, and manages and manages the component. Subsequently, when the application service element requests dialogue processing to the dialog processing unit 13 (DHA: Dialogue HAndling), the dialog processing unit assigns a new transaction number to the intelligent network service (FP: Free Phone, CC: Credit Call, PR: Premium Rate, etc.). Regardless of the type, the transaction number is stored and managed in the dialog number management table by assigning transaction numbers in order as the maximum number of processes that the main processor can create, and then the transaction processing unit 15 (THA: Transmit transaction processing primitive with Transaction HAndling). The transaction processing unit reconstructs the received user data, stores the transaction number in the transaction number management table, and transmits a TCAP (Transaction Capabilities Application Part) message to the signaling connection control unit 17 (SCCP). do.

As described above, the transaction number assignment method can achieve the maximum effect by reducing the waste of unnecessary resources and optimally utilizing the same grant method even if new services are continuously developed and applied in the future. It is effective to provide a standardized interface that can be provided.
