1 is a configuration diagram of an embodiment of an integrated access node system to which the present invention is applied. Referring to Figure 1 will be described in detail the configuration of the integrated access node system to which the present invention is applied.

The MAIN 102 includes an access node 103 including a communication management network delegate function block 109 and a supervisory control unit (Operation, Administration and Maintenance; hereinafter referred to as "OAM") 108 and a maximum of 32 local devices ( Optical Network Unit (hereinafter referred to as " ONU ") 104. At this time, the access node 103 and the ONU 104 is connected via a double line 106 of STM-4 class.

Therefore, even if a failure occurs in one of the dual lines, service can continue between the access node 103 and the ONU 104. In addition, since the MAIN 102 and the service node 101 are connected by using the ST-1 grade dual line 105, the service reliability is provided by providing a redundant line to all service subscribers connected to the corresponding service node. It is improving.

The connection between the local station 104 and the subscriber station 107 is not realized in consideration of economical efficiency.

The access node 103 includes a communications management network delegate function block 109 and an OAM 108. The OAM 108 functions to monitor the communications management network delegate function block 109 via an Inter Processor Communication message.

The communication management network delegate function block 109 sets the signals that the integrated access node system 102 can accept and the equipment and status of the hardware that configures them. In addition, the integrated access node system 102 evaluates / reports the performance of the network connected thereto, and recognizes, reports, diagnoses, and recovers a failure.

2 is a diagram illustrating an embodiment of a communication management network delegate function block performed in the access node of FIG. 1 to which the present invention is applied. This will be described in detail with respect to the communication manager network functional block.

The communication management network delegate function block 109 includes a configuration management object unit 211, a failure management object unit 212, a performance management object unit 213, and a support object unit 214.

The configuration management object unit 211 accommodates signals that can be accommodated in the integrated access node system 102 and objects related to facilities and state control functions of the hardware configuring the same.

The failure management object unit 212 recognizes and reports a failure of a network and a network element, and performs a function related to diagnosis and recovery.

The performance management object unit 213 performs evaluation and reporting on the performance of the network and the network elements.

The support object unit 214 is composed of objects of a function supporting the configuration, failure, and performance management object units 211, 212, and 213.

In the integrated access node system 102, an information base composed of the above objects is required to perform standardized management functions as a delegate by accessing the TMN. In particular, the configuration management object unit 211 maintains the transmission signal object and cross-connection management object, multi-section switching management object, device unit, unit switching object, etc. in the ATM transmission, SDH transmission, DSL, V5 management functions, etc. Perform overall configuration management of system 102.

Figure 3 is a flow diagram of an embodiment of a standard management operation processing error prevention method according to the present invention. The method of the present invention will be described in detail with reference to FIG. 3.

The delegate function is performed when the integrated access node system 102 is operated. The Common Management Information Protocol (CMIP) request of the communication management network manager is received from an operating system (hereinafter referred to as "OS") (301). Here, the CMIP request content means all standard CMIP request content received by the integrated access node system, such as M-GET, M-SET, M-ACTION, M-CREATE, M-DELETE, and the like. Thereafter, the integrated access node system 102 transmits a downlink message to the monitoring control unit 108, and generates a unique serial number to match the response message later (302) and stores it in a table with the contents of the management operation request. (303). For example, in the case of cross linking, the contents of the management operation request may include start and end points, directionality, and signal characteristic information. When a message including the management operation request contents and the unique serial number is constructed, the operation request message is sent to the OAM (304), and the state transitions to the start state.

When a response to the operation request message is received from the OAM 108 (305), a unique serial number is extracted (306) from the management operation request contents given at the management operation request. The extracted unique serial number is searched in the table to determine whether it exists (307).

If the extracted unique serial number exists in the table, it is determined whether the processing result of the contents of the operation request is the same as the contents of the management operation request (308). If the requested content and the processed content are the same, the response result is reflected in the corresponding object (309). Thereafter, since the processing of the contents of the operation request is completed, the unique serial number maintained by the communication network delegate function block 109 is deleted from the table (310), and a normal processing response is sent to the OAM 108 (311), and the start is performed. Transition to state.

If the extracted unique serial number does not exist in the table (307), or if the requested content and the processed content are not the same (308), or if it is received as a response message but the unique number does not exist, the operation processing error is reported. Transmit to 108 (312). Thereafter, by sending the return request message to the OAM 108, restarting is performed from the beginning so that the content and processing of the management operation request match. Finally, the unique serial number maintained by the communication management network agent function block 109 is deleted (314), and the state transitions to the start state.

Meanwhile, communication management network operation request reception and supervisory control response / report reception are performed permanently in the process in the communication management network delegate function block 109, and if the termination signal is received from the OS (315), the process execution is terminated. 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 to the drawing.

In the present invention as described above, since the CMIP request is accurately reflected in the system device and agent management information base in the integrated access node system, the CMIP operation requested by the administrator to the integrated access node system is reliably performed, and the response is guaranteed. There is.
