Field of the Invention [0001] The present invention relates to a method for bypassing a transmission path for a fault transmission line for a subscriber line service in a communication network management system, and a computer readable recording medium recording a program for realizing the same.

Conventional subscriber line service can not share the DCS information installed at a long distance in the country by managing the transmission channel and channel information of the digital cross-connect system (hereinafter referred to as "DCS"), respectively, In case of occurrence, it is very difficult to set the bypass section and identify the free line. As a method for resuming the subscriber service in case of transmission path failure in DCS section, the failure information displayed on the terminal connected to the DCS device is analyzed to recognize the failure section, the channel information of the failed DCS is extracted, and the subscriber affected by the failure. A list must be prepared.

Therefore, conventionally, the DCS information is distributed and managed, so it is impossible to grasp the overall network configuration situation, and in particular, in case of a failure in which subscriber service is not possible, it takes a lot of time to identify a subscriber who has a failure and has a minimum cost of bypassing a failure section. Since it takes a lot of time to select the path and control the DCS manually for the selected path, there is a problem that it is impossible to provide the service of the dedicated line during the time required for repairing the obstacle or the bypass transfer time of the faulty transmission line.

Therefore, the present invention devised to solve the above problems, the failure of the apparatus and transmission path constituting the network in a dedicated communication network composed of digital circuit distribution device (DCS) to reduce the down time of subscriber line service The purpose of the present invention is to provide a method for bypassing a transmission path of a fault transmission line that monitors whether a subscriber line is interrupted to a normal spare line and monitors whether or not a service has occurred, and a computer-readable recording medium recording a program for realizing it. .

It features.

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

Fig. 1 is an exemplary configuration diagram of a digital dedicated communication network management system to which the present invention is applied, and includes a digital line distribution device 101, a terminal station 102, an X.25 communication network 103, a central control unit 104, and a database ( 105 and an operating terminal device 106.

As shown in the figure, in order to provide a dedicated line service to a subscriber, a DCS, which is a digital line distribution device 101 having a digital line connection function, is installed in a communication network, and a dedicated communication network is used by using transmission paths connecting the respective DCSs. The terminal 102 is connected to the subscriber service line and performs the gateway function of the subscriber line and the DCS network. The dedicated communication network management system is composed of a host computer 104 for managing DCS and end station devices, and a database 105 for storing facility and subscriber information. Operators perform various functions of the system using the terminal device 106. do. In a dedicated network management system that is computerized a series of processes to construct a dedicated line that guarantees a constant speed for the subscriber section, and establishes a line that can always be used, it maximizes the subscriber's dedicated line service time by searching for and bypassing the bypass transmission line in the event of circuit configuration and failure Plays a role in ensuring

2 is an explanatory diagram of alarm recognition and bypass switching in a digital-only communication network management system to which the present invention is applied.

As shown in the figure, a series of processes of bypass switching from recognition of alarm data recognized by the DCS itself will be described. The communication function unit 202 receiving the response of each DCS 201 receives the fault information from each DCS 201 and transmits the fault information of the corresponding DCS to the alarm analysis function unit 203 in the form of alarm data. . Then, the alert analysis function unit 203 analyzes the received alert data and transmits the fault information output by the analysis to the subscriber management function unit 204. At this time, the subscriber management function unit 204 refers to the information stored in the subscriber facility information database 205, which has already been established, based on the received failure information, and creates a subscriber list belonging to the failure section.

That is, the subscriber management function unit 204 extracts information of subscribers belonging to two digital line distribution apparatuses adjacent to the obstacle section, which is subscriber information previously stored in the subscriber facility information database 205, and based on the extracted subscriber information. Bypass information is generated through the transmission section. As a criterion for selecting the least cost route that bypasses the obstacle section, there are many transmission paths between the digital circuit distribution apparatuses, and a route having the smallest route device is selected. When there are a plurality of subscriber lines in a failure section, the above process is repeated for each subscriber line, and the detour path information extracted for each line is transmitted to the bypass transfer function unit 206.

Accordingly, the bypass switching function unit 206 requests the DCS 201 to connect the circuit through the selected minimum cost transmission path path, and if the bypass path of the failure circuit is successfully connected as a result of the DCS circuit configuration, the data is output. Store in the base and notify the subscriber that service is resumed. This series of tasks are performed using the operator terminal device 207 installed to manage the DCS 201.

3 is a flowchart illustrating an embodiment of a method for bypassing a transmission path of a failure path for a subscriber line service according to the present invention.

As shown in the figure, the bypass switching program is operated (301), the fault transmission path and DCS facility failure information is retrieved (302), and the presence of the disabled facility is found (303) if the disabled facility exists, the service failed subscriber. The information is retrieved (304).

Subsequently, it is determined whether to perform the switchover of the bypass transmission path (305), if the bypass switchover is not performed, waiting for failure recovery (313), and if the bypass transfer is performed, the inter-DCS transmission path information for the subscriber line belonging to the failure transmission path And DCS failure information is used to extract the minimum cost transfer information for each subscriber line (306). It is determined whether to transfer the extracted same section (307). In operation 308, if the extracted same section is not transferred, another transmission path via another section is searched (309).

Subsequently, the DCS circuit control command is transmitted to the DCS to receive a result from the DCS (310), it is determined whether to resume the subscriber service (311), and if the subscriber service is not resumed, the bypass transmission path extraction process is repeated, and the subscriber When the service resumes, the subscriber facility information is updated (312).

For reference, when an operator runs a program in the operation terminal device to perform the bypass switching task, the operator accesses a database by itself and provides a control screen for the operator. In the process of searching for information on the occurrence of the failure, the time of occurrence of the failure and the cause of the failure are displayed on the operator screen. The operator checks the fault history to determine whether the switchover is bypassed and sends a trouble repair request if the cause of the fault is removed quickly. When the bypass switching is determined, the subscriber line information in operation is extracted and the switching line is ranked according to the priority of each subscriber line. The operator decides whether to switch the bypass route to the bypass route by extracting the bypass route section information of each subscriber having the minimum cost based on the already established transmission line and fault information. Search for transmission path and channel information belonging to the determined section. DCS control commands are generated and sent to the DCS for actual circuit configuration, and the changed subscriber and facility information is stored in the database.

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.

As described above, the present invention provides a database of a circuit distribution apparatus of a dedicated communication network, and when a failure of a service of a dedicated line subscriber is interrupted in a dedicated communication network management system that centrally manages a control line, a failure and associated subscriber line management is performed. It is easy to search the normal bypass transmission path with the lowest cost, and control the circuit configuration of the circuit distribution device to match the transmission path information of the dedicated communication network management system in real time, and minimize the service downtime of the dedicated line subscriber. It can be effective.
