Description

Remote control and management method for exchange

The present invention relates to a remote network management method for an exchange, and more particularly, to a remote control and management method for an exchange capable of monitoring and controlling performance of an exchange at a remote location using a telecommnication management network (TMN) management technique. .

Until now, management of exchanges was only possible with input devices (eg PCs or terminals) connected at close range. Therefore, in order to receive information on control, performance monitoring, alarm, alarm, and structure of the exchange, and to control the exchange, there is a hassle that the administrator must move to the place where the corresponding exchange is always located.

The present invention has been made to solve the above-mentioned hassle, and the object of the present invention is to provide a method for the administrator to control and manage the corresponding exchange from a remote location using the TMN management technique.

In order to achieve the above object, a remote control and management method for a switch according to the present invention is a method for controlling and managing a switch using a remote system, wherein the administrator uses predetermined remote management information using the remote system. If a service (CMIS) is requested, sending a predetermined common management information service request to a manager agency process located at a short distance of the exchange via a common management information protocol (CMIP); The manager proxy process may include creating or searching for a management object instance related to the received common management information service request; Creating or searching for an associated management object instance, creating a dedicated buffer; Transmitting an input command (COD) of an exchange generated from an associated management object instance from an administrator agency process to the exchange via TCP / IP; When a predetermined output message (POD) is received from the exchange by an administrator's agent process, analyzing the received predetermined output message and searching a dedicated buffer; writing a predetermined output message received by the searched dedicated buffer; And awaking the management object instance related to the predetermined output message, reading the predetermined output message POD written in the dedicated buffer, and transmitting the predetermined output message POD to the remote system from the manager's agent process.

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

1 is a system block diagram for performing a remote control and management method for a switch according to the present invention, which transmits and sends a CMIS (Common Management Information Service, or CMIS) request of a TMN manager located at a remote location. The remote system 100 configured to receive the result message of the CMIS request, the remote system 100 and the remote system 100 is configured to transmit and receive data from the CMIP (Common Management Information Protocol, hereinafter referred to as CMIP) from the remote system 100 Receives the CIMS request of the administrator to be sent, sends an input command corresponding to the received CIMS request (COD: Command Of Description, hereinafter abbreviated as COD) to the exchange 120, and outputs an output message ( A predetermined COD from the short-range system 110 and the short-range system 110, configured to send a POD: Printing Of Description (hereinafter referred to as POD) to the remote system 100 side. Once applied, is transmitted to the process, and consists of a heat exchanger (120) for transmitting the operating result to the POD hence form.

2 is an operation flowchart of a remote control and management method for an exchange according to the present invention.

1 and 2 will be described the operation of the remote control and management method for the exchange according to the present invention.

When a certain administrator authorizes a command for performing a network management function for the exchange 120 through the remote system 100, the manager process 101 outputs a corresponding CMIS request signal based on the TNM. The CMIS request signals include M (Management) -Create, M-Delete, M-Get, M-Set, M-EventReport. In this case, M-Create requires creation of the instance, M-Delete requires removal of the instance, M-Get requires the current situation, and M-Set requires the conversion of the situation. .

The CMIS request output from the manager process 101 is CMIPed through the OSI stack and sent to the local area system 110. The short range system 110 is a workstation that is connected to the corresponding switch 120 by TIP / IP. The short-range system 110 also receives the CMIS request transmitted through the CMIP process through the OSI stack 111. The OSI stack 111 sends the received CMIS to the management agent process 112.

If a predetermined CMIS request is received in step 202, the management agent process 112 proceeds to step 204 to analyze the received CMIS. As a result of the analysis, in the case of M-Create, the process proceeds to step 206 to create a related management object instance, and if the creation of the management object is reflected in the network management of the exchange in real time, the corresponding information is reflected. Generates a COD The creation of this COD ensures the consistency of the exchange period with the managed object instance created by the administrator's CMIS request.

In the case of M-Get, the property value of the managed object instance is obtained. M-set means the property value is changed. This also creates the relevant COD in the same way as M-Create if the changed attribute value should be reflected in the exchange. M-Delete sends a related COD to the exchange to remove the related object, and creates a related COD to ensure consistency with the exchange.

When the appropriate COD is generated for the received CMIS request in this way, the management agent process 112 proceeds to step 208 to create a dedicated first-in, first-out buffer (hereinafter referred to as FIFO). The FIFOs generated at this time are for the generated CODs, one for each generated COD.

The management agent process 112 then proceeds to step 210 and transmits the COD generated from the related management object instance to the exchange 120 through the communication control unit 113. The flow proceeds to step 212 to maintain the standby state.

The communication control unit 113 further includes a port for transmitting the COD output from the management agent process 112 to the exchanger 120 and a receiving port for receiving the POD to be sent from the exchanger 120. Control communication between the 120.

On the other hand, the exchanger 120 receives the COD transmitted from the short-range system 110 through the Operation & Maintenance Center Interface (OMI) 121, and receives the received CODs in the exchanger 120 through the first through Nth. It transmits to the corresponding process among the processes 122-124. When the POD corresponding to the transmitted COD is applied to the OMI 121 from the process, the OMI 121 transmits the corresponding POD to the communication control unit 113 of the short range system 110 connected by TCP / IP.

When the POD is received from the communication control unit 113 in step 214, the management agent process 112 that has maintained the standby state proceeds to step 216 and searches for a related FIFO among the generated FIFOs.

When the associated FIFO is searched, it writes the received POD to the searched FIFO. In step 20, the management object instance is woken up. In operation 222, the POD stored in the related FIFO is read using the management object instance. In step 224, the read POD is analyzed, the related management object is generated, and the generation of the management object is reported to the remote system 100 through the OSI stack 111.

The remote system 100 knows from the creation of this managed object instance that the network management associated with this managed object instance is operating at the exchange, the value is confirmed through an M-Get request, and this managed object instance is no longer present. If you do not want to operate the management object instance by sending an M-Delete, the exchange 120 can be managed from a remote location.

As described above, the present invention provides a method for ensuring interoperability based on the TMN during the exchange with the remote system, thereby enabling remote management and control of the exchange.
