If there is no error in the result of the check, the check is performed on the information having a dependency in the parameter information. If there is no error, the middleware procedure-middleware message parameter and middleware server name and middleware server are configured by adding the information required to perform ATM PVC point-to-point connection control to the parameter information of the inputted human-machine interface (HMI) command. ATM PVC connection information is transmitted to the calling party PPCCF 1121-1 by calling a number indicating a processor, a parameter of a middleware execution end time, and the like. If there is an error in checking whether the input parameter conforms to the input command format or checking the information having dependency among the parameter information, an error result indicating that the input parameter is incorrect in the operator workstation is output (202). The originating PPCCF 1221-1 receiving ATM PVC connection information from the PPCCIF detects whether there is an ATM PVC connection to be registered in the ATM PVC connection relation 1215, and if the same ATM PVC connection already exists, the same ATM PVC connection. Parameter information and additional information of the human-machine interface (HMI) command passed when called from PPCCIF 1112 if the same ATM PVC connection does not exist (204). Request 207 the CRCF 1212 from the calling party VPI / VCI resource allocation corresponding to the calling party GSMP label. The CRCF 1212 that has been requested to allocate the source VPI / VCI resources checks whether the required VPI / VCI can be allocated, and if so, allocates the VPI / VCI and the required traffic bands and assigns the source PPCCF 1221-1. The assigned VPI / VCI is forwarded to (208). Also, the calling party PPCCF 1121-1 becomes a middleware client for the called party connection processing and calls the called party connection processing middleware procedure, and sends a human machine interface (HMI) command to the called party PPCCF 1211-2. The destination side connection information consisting of the parameter information and additional information of is transmitted (209). The called party PPCCF 1211-2 uses the parameter information and additional information of the Human-Machine Interface (HMI) instruction transmitted in the call to allocate the called party VPI / VCI resources corresponding to the called party GSMP label by using the CFCF. Request 1221, the called party VPI / VCI resource allocation. The requested CRCF 1212 checks whether the required VPI / VCI is assignable, and if so, allocates the VPI / VCI and the requested traffic band and assigns the allocated called party VPI / VCI to the called party PPCCF ( 1211-2). The called party PPCCF 1211-2 stores the called party connection information in the ATM PVC connection relation 1215 (211, 212), and the called party assigned to the calling party PPCCF 1121-1 from the CRCF 1212. Pass 210 the VPI / VCI. The calling party PPCCF 1121-1 receiving the called party VPI / VCI stores the calling party VPI / VCI and the called party VPI / VCI as the calling party label and the called party label of the GSMP, respectively, and the human-machine interface (HMI). After extracting the GSMP port number from the logical port number, which is one of the parameters of the command, the traffic parameter and band information are transmitted to the GMPHF 1213 (215) to request the ATM PVC connection to the switch plane (13). After receiving the ATM PVC connection request, the GMPHF 1213 encodes the ATM PVC connection request message received from the originating PPCCF 121-1 according to a GSMP protocol message, and then converts the encoded ATM PVC connection information into a GSMP protocol. Transmit to the GSPHF 1311 (217). The GSPHF 1311 receiving the encoded GSMP ATM PVC connection information message decodes the encoded GSMP ATM PVC connection information message, and decodes the decoded source and destination ATM PVC connection information, respectively, from the calling party's AIMCF 1411-1. And forwarding (219, 221) to the destination AIMCF (1411-2) using internal InterProcessor Communication (IPC) to request that the ATM PVC connection be substantially established. The originating AIMCF 1411-1 receiving the originating ATM PVC connection information from the GSPHF 1311 sets up the originating ATM PVC connection, and then transmits the result of the connection to the GSPHF 1311 (220). After receiving the destination ATM PVC connection information, the destination AIMCF 1411-2 establishes the destination ATM PVC connection, and transmits the result of the connection to the GSPHF 1311 (222). GSPHF 1311, which has received the results from the calling party AIMCF (1411-1) and the calling party AIMCF (1411-2) (220, 222), encodes the result of performing ATM PVC connection according to the GSMP protocol message. The ATM PVC performance result encoded using the GSMP protocol is transmitted 213 to the GMPHF 1213. Receiving the encoded ATM PVC performance result, the GMPHF 1213 decodes the encoded ATM PVC performance result and then transmits 216 the decoded ATM PVC performance result to the calling party PPCCF 1121-1. The originating PPCCF 1121-1 receiving the ATM PVC execution result from the GMPHF 1213 stores the calling side ATM PVC connection information in the ATM PVC connection relation 1215 (205, 206), and then performs the ATM PVC. The result is passed 204 to the PPCCIF 1112. The PPCCIF 1112 outputs 202 the ATM PVC performance result to the operator workstation 111.

4 is a flow diagram of an embodiment of the functionality of the ATM PVC point-to-point connection function using middleware implemented on an open multiservice exchange. When PPCCIF receives a Human-Machine Interface (HMI) command for registering an ATM PVC connection from the operator's terminal (401), it checks whether the parameter is entered according to the input command format (402) and if there is an error (403). An error result is output to the terminal (404), and if there is no error (403), a check is performed on information having a dependency among parameter information (405). If the result is an error (406), an error result is output to the operator terminal (404). If there is no error (406), the ATM PVC point-to-point connection control function is applied to the parameter information of the inputted human-machine interface (HMI) command. After adding 407 information necessary to perform, the middleware procedure of the calling PPCCF is called 408 to transmit 409 the ATM PVC connection information to the PPCCF. Upon receiving the ATM PVC connection information (410), the PPCCF detects whether the ATM PVC connection to be registered in the ATM PVC connection relation exists (411) and transmits an error result to the PPCCIF if the same ATM PVC connection already exists (412). 413), the PPCCIF receiving the error result (414) outputs the error result to the operator terminal (415). However, if the same ATM PVC connection does not exist (412), the calling party's originating VPI / VCI resource allocation, which is the originating GSMP label, is used by using the parameter information and additional information of the Human-Machine Interface (HMI) command passed in the middleware procedure call from PPCCIF. Ask the CRCF (417). The CRCF, which is requested to allocate the source VPI / VCI resource, allocates an assignable VPI / VCI (418), and transmits the allocated VPI / VCI to the calling party PPCCF (419). The calling party PPCCF, which has received the allocated calling party VPI / VCI (420), calls the calling party connection processing middleware procedure 421 to send the called party connection information to the called party PPCCF for the called party connection processing (422). The called party PPCCF, which has received the called party connection information (423), allocates the called party's VPI / VCI resource, which is the called party's GSMP label, using the parameter information and additional information of the Human-Machine Interface (HMI) command, which was passed in the middleware procedure call. For example, the CRCF block requests the called party VPI / VCI resource allocation to the CRCF block (424), and receives the called VPI / VCI resource allocation request (425) to allocate the allocated VPI / VCI (426). Then, the allocated called party VPI / VCI is forwarded to the called party PPCCF (427). The called party PPCCF that has received the allocated called party VPI / VCI (428) stores the called party connection information in the ATM PVC connection relation (429) and forwards the called party VPI / VCI to the calling party PPCCF (430). The calling party PPCCF that receives the called party VPI / VCI (431) determines the calling party VPI / VCI and the called party VPI / VCI as the calling party label and the called party label of the GSMP, and the parameters of the human-machine interface (HMI) command. After extracting the GSMP port number corresponding to one of the logical port number, and transmits the traffic parameter and band information to GMPHF request ATM PVC connection in the switch plane (432). Receiving the ATM PVC connection request (433), GMPHF transmits (434) the ATM PVC connection information encoded in the GSMP protocol message to the GSPHF using the GSMP protocol. GSPHF, having received the GSMP ATM PVC connection information message (435), forwards the source and destination ATM PVC connection information to the source and destination AIMCFs, respectively, requesting 436 that the ATM PVC connection is substantially established. Upon receipt of the ATM PVC connection request (437), the AIMCF establishes an ATM PVC connection (438) and sends the connection performance result to the GSPHF (439). The GSPHF receiving the connection performing result from the AIMCF (440) transmits the connection performing result to the GMPHF using the GSMP protocol (441), and the GMPHF receiving the connection performing result (442) sends the connection performing result to the PPCCF. The PPCCF receiving the connection result (444) stores the originating ATM PVC connection information in the ATM PVC connection relation (445), and then transmits the result of the connection to the PPCCIF (446). . Upon receiving the connection result, the PPCCIF 447 outputs the received connection result to the operator terminal 448.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.
