Preferred embodiment of the invention

The core idea of the present invention is that the OMC system and the LMT system are simultaneously connected to the network device, and then the configuration authority transfer and filtering mechanism is used to ensure that the OMC system and the LMT system are mutually exclusive operations during the operation and maintenance of the network device.

Specifically, the OMC system can transfer the configuration rights of the network device that it has to the LMT system, so that the LMT system can obtain the transferred configuration authority, that is, the network device that the LMT system has in the configuration permission transfer validity period. The configuration authority also has the configuration authority transferred by the OMC system, and the OMC system no longer has the transferred configuration authority, thereby ensuring mutual exclusion between the OMC system and the LMT system. Preferably, the data of all configuration rights of the network device owned by the OMC itself may be stored in the filter, so that when the OMC system does not transfer the configuration rights of the network device that it has, the LMT system may be set in the filter. The data does not have configuration rights, thus ensuring mutual exclusion between the OMC system and the LMT system.

The implementation of the technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

An operation and maintenance device for a network device, as shown in FIG. 1, includes a communication module, a filter, a configuration rights management module, and an operation processing module. The functions of each part are described below.

The privilege management module is configured to separately store configuration rights of the OMC system and the LMT system, where the configuration permission of the storage LMT system is LMT when the OMC system transfers the configuration authority of the OMT system to the configuration authority transfer period of the LMT system. The configuration authority of the network device owned by the system itself and the configured configuration authority transferred, the configuration authority of the storage OMC system is to remove the configuration authority of the OMC system other than the transferred configuration authority; when the OMC system does not have its own When the configuration permission of the network device is transferred to the LMT system, the configuration authority of the storage OMC system is all the configuration rights of the network device that it has, and the configuration permission of the storage LMT system is all the configuration rights of the network cable device that it has. And does not have configuration rights to the data in the filter;

The OMC system may transfer the configuration rights of the network device that the OMC system has to the LMT system according to the request of the LMT system, and the configuration authority transferred by the OMC system may be all or part of the configuration rights of the network device that the OMC itself has. ;

Configuring the privilege transfer validity period means: transferring the configuration authority of the network device that the OMC system has to the LMT system to the OMC system to recover the configuration rights of the network device that it has;

The communication module is mainly used for communication between the OMC system and the LMT system and the operation processing module, for example, forwarding the operation initiated by the OMC system or the LMT system to the operation processing module;

The communication module can also be used for communication between the OMC system and the LMT system, for example, forwarding the request for configuration authority transfer initiated by the LMT system to the OMC system, and reclaiming the OMC. The notification of the configuration permission is forwarded to the LMT system.

An operation processing module, configured to receive and execute an operation initiated by the OMC system and the LMT system, where the configuration operation initiated by the OMC system and the LMT system is received and executed according to the configuration authority of the OMC system and the LMT system in the configuration rights management module;

The operation processing module may further forward the request for configuration authority transfer initiated by the LMT system to the OMC system, and forward the notification that the OMC reclaims the transferred configuration authority to the LMT system.

The operation processing module is further used to report the operation content of the LMT system to the OMC system when the configuration authority of the LMT system is the configuration authority of the network device and the configured configuration authority of the LMT system.

The filter mainly stores data of all configuration rights of network devices owned by the OMC system.

The process of implementing the mutually exclusive operation of the OMC system and the LMT system by the above device is described below. The process is shown in Figure 2 and includes the following steps:

Step 200: Connect the OMC system and the LMT system to the network device at the same time;

Step 201: Store data of all configuration rights of the network device owned by the OMC system into the filter;

Step 202: Determine whether the OMC system transfers the configuration authority of the network device that it owns to the LMT system, and if yes, proceeds to step 203, otherwise proceeds to step 206;

The OMC system can transfer the configuration rights of the network devices it has to the LMT system according to the request initiated by the LMT system, or actively transfer the configuration rights of the network devices that it has to the LMT system, and the transferred configuration rights can be Is all or part of the configuration rights of the network device that the OMC system has;

Step 203: Determine whether the configuration authority transferred by the OMC system is within the validity period of the configuration authority transfer, and if yes, proceed to step 204, otherwise proceed to step 206;

In this step, the configuration permission transfer validity period is from the OMC system transferring the configuration authority of the network device that the OMC system has to the LMT system until the OMC system reclaims the configuration authority of the network device that the OMC system has; therefore, it can be determined whether the OMC system is Retrieve the transferred configuration authority to determine whether the transferred configuration authority is within the validity period of the configuration authority transfer; When the configuration rights transferred by the OMC system are within the validity period of the configuration rights transfer, the OMC system cannot configure the data of the transferred configuration rights, that is, the OMC no longer has the configuration rights transferred to the LMT system.

When the configuration rights transferred by the OMC system are not within the validity period of the configuration rights transfer, that is, the OMC system re-owns the configuration rights transferred to the LMT system, and the LMT system no longer has the configuration rights;

Step 204: Set the configuration authority of the LMT system to the configuration authority of the network device owned by the LMT system and the transferred configuration authority (the transferred configuration authority means that the LMT system has partial or full configuration permission for the data in the filter. The configuration authority of the OMC system is set to remove the configuration authority of the network device that the OMC system has other than the transferred configuration authority; Step 205: Receive various configuration operations within the scope of the configuration authority initiated by the OMC system and the LMT system When the LMT system performs the configuration operation on the network device, the content of the configuration operation performed by the LMT system is reported to the OMC system, and the process ends.

In this step, when the content of the configuration operation performed by the LMT system is reported to the OMC system, the OMC system can update the configuration of the network device in real time according to the received content, so as to ensure that the data on the network side and the local device are consistent.

Step 206: Set the configuration authority of the OMC system to all the configuration rights of the network device that the OMC has, and set the configuration authority of the LMT system to all the configuration rights of the network device that the LMT has, which does not have the data in the filter. Configuration permission;

Step 207: Receive various configuration operations within the scope of the configuration authority initiated by the OMC system and the LMT system, and end the process.

In the above process, when the OMC transfers the configuration rights of its own network device to the LMT, during the configuration operation of the LMT system, when the OMC system forcibly reclaims the transferred configuration rights, when the LMT system performs the configuration operation again, The LMT system configuration operation fails.

Specifically, FIG. 3 is a flowchart of the OMC system actively transferring configuration rights to the LMT system, and the LMT system operates on the network device, and the process specifically includes the following steps:

S301: The OMC system and the LMT system respectively establish a link with the network device; S302: The OMC actively transfers the configuration authority to the LMT system, and after configuring the permission transfer, respectively updates the configuration rights of the OMC system and the LMT system;

S303: determining whether the LMT system requests the transfer configuration permission from the OMC system, if yes, proceeding to S304; otherwise, proceeding to S305;

S304: Determine whether the OMC system agrees to transfer the configuration authority to the LMT system. If yes, update the configuration rights of the OMC system and the LMT system respectively according to the configured configuration authority of the transfer, and then enter S305; otherwise, directly enter S305;

S305: The LMT system initiates operation on the network device.

S306: determining whether the operation initiated by the LMT system is in the filter, if yes, proceeding to step S307, otherwise proceeding to S315;

S307: determining whether the operation initiated by the LMT system is within the scope of the LMT system (that is, whether the configuration authority of the OMC system is transferred to the LMT system), if yes, go to S308; otherwise, go to S313;

S308: Perform an operation on the network device by the LMT system, and actively report the execution to the OMC system;

S309: determining whether the operation of the LMT system is completed, if yes, proceeding to S312; otherwise, proceeding to S310;

S310: Determine whether the OMC system forcibly withdraws the configuration authority, and if yes, go to S311; otherwise, return to S305;

S311: When the OMC system forcibly reclaims the configuration authority, the configuration rights of the OMC system and the LMT system are respectively updated according to the reclaimed configuration authority, and it is determined whether the network device has received the operation command currently initiated by the LMT system, and if yes, go to S315. Otherwise, when the operation command arrives at the network device, the network device prompts the LMT system not to perform the operation, and proceeds to S316;

In this step, when the OMC system forcibly reclaims the configuration authority, if the network device has not received the operation command currently initiated by the LMT system, when the pending command arrives at the network device, the LMT system is prompted not to perform the operation, and further The LMT system requests the OMC system to reclaim the configuration authority. At this time, the configuration rights of the OMC system and the LMT system are respectively updated according to the configured configuration authority reclaimed, and the process goes to S316. S312: Apply for the OMC system to reclaim the configuration authority, and proceed to S316;

In this step, the LMT system requests the OMC system to reclaim the configuration authority. Specifically, the configured requisitioned configuration authority may be the configuration permission of one or more data that the LMT has operated, or may not be required by the LMT system. Some or all of the configuration rights, for example, apply for the OMC system to reclaim the cell configuration rights, or apply for the OMC system to reclaim all the configuration rights of its active transfer.

S313: Determine whether the LMT system requests the transfer permission to the OMC, wherein the configured transfer permission includes the current operation permission, and if yes, proceeds to S314, otherwise, the network device prompts the LMT system not to perform the operation, and proceeds to S309;

S314: determining whether the OMC system agrees to the request for transferring the configuration authority, and if yes, updating the configuration rights of the OMC system and the LMT system according to the configured configuration authority of the transfer, and then moving to S308; otherwise, proceeding to S309;

S315: The network device responds to the operation of the LMT system, and proceeds to S316;

S316: The operation of the LMT system ends.

Figure 4 is a flow chart showing the OMC system inactive transfer configuration authority to the LMT system and the LMT system operating on the network device. The process is basically the same as the process shown in Figure 3, except that the OMC system and the LMT system are respectively After establishing a link with a network device, the OMC does not actively transfer configuration rights to the LMT system.

Figure 5 is a flow chart showing the operation of the network device by the OMC system. The process includes the following steps:

S501: The OMC system and the LMT system respectively establish a link with the network device;

S502: The OMC system initiates an operation on the network device.

S503: Determine whether the OMC system transfers the configuration authority to the LMT system, and if it is to S504, otherwise go to S505;

The OMC system transfer configuration authority referred to in this step to the LMT system means: The OMC system transfers the configuration authority to the LMT system, and the transferred configuration authority is not reclaimed, wherein the OMC system When the configuration permission is transferred to the LMT system, the configuration permission may be actively transferred to the LMT system, or the configuration permission may be transferred according to the request initiated by the LMT system.

S504: Determine whether the operation of the network device initiated by the OMC is within the configuration authority of the OMC system, and if yes, go to S505, otherwise, S506;

S505: The network device responds to the operation initiated by the OMC, and the operation of the OMC system ends.

S506: The network device prompts that the LMT system does not allow the operation, and the operation of the OMC system is terminated.

The following describes the process in combination with a specific application scenario. For example, after the OMC system and the LMT system are respectively connected to the network device, the configuration permission information of the data stored in the filter is as shown in Table 1 below. When the LMT system performs cell configuration on the network device. The network device may prompt the LMT system not to perform the operation, because it can be seen from the above Table 1 that the cell configuration stored in the filter has a right switch to the LMT system configuration of 0, that is, the LMT system is not allowed to perform cell configuration. Operation, at this time, only the OMC system can perform cell configuration. Similarly, when the LMT system performs any operation on the network device in sequence 1 - 5 in Table 1, the network device also prompts the LMT system not to perform the operation; only the LMT system is connected to the network. When the operation of the device is not in the filter, the network device responds to the operation of the LMT system.

Table 1 shows the list of data stored in the filter and its configuration permissions.

For another example, the OMC system needs to handle a lot of transactions, and cannot take into account the special requirements of a network device. When the time is up, the OMC system transfers the configuration authority to the LMT system, and the LMT system can operate on the data of the transfer configuration authority. For example, when network device A requires two cells to be established, and other network devices do not have this requirement, the OMC system has to deal with a large number of network device transactions, and has no attention to the unique needs of network device A. The configuration permission of the configuration is transferred to the LMT system. At this time, the configuration rights of each data stored in the filter are as shown in Table 2. The LMT system has the right to configure the cell at this time, and then the LMT can perform cell configuration on the network device. After the configuration is complete, the network device reports the configuration result to the OMC system. The real-time update of the OMC system ensures that the data is consistent with the network device. After the cell configuration is performed, the LMT system requests the OMC system to reclaim the configuration rights of the cell configuration, and the OMC system reclaims the rights. If the LMT is in the cell configuration, the OMC system is processed and idle, and you want to configure the cell of the network device A. However, since the OMC system has transferred the rights of the network device A cell configuration to the LMT system, the cell cannot be configured. The network device performs the configuration request and reports the execution result to the OMC system; if the configuration command of the LMT system does not reach the network, if the LMT system configuration command reaches the network device A, the network device performs the configuration request and reverts the execution result to the OMC system; Device A, then the LMT can no longer perform cell configuration operations on network device A.

Table 2 shows the information stored in the filter and its configuration rights after the OMC actively transfers the configured permissions.

For example, if network device A fails, the project maintenance personnel goes to network device A to process the fault. It is found that the transmit power of device A is too small, resulting in poor transmit signal quality. It is necessary to modify the transmit power parameter of the board to confirm the problem, because the OMC system Linked to network device A, LMT system cannot be repaired The transmission power parameter is changed, and the LMT system requests the OMC system to configure the transmission power. If the OMC system agrees to transfer the configuration authority of the transmission power to the LMT system, the configuration rights of the data stored in the filter are as shown in Table 3. The LMT system can change the transmit power to confirm whether it is a problem caused by too small transmit power. If it is confirmed that the transmit power is too small, modify the transmit power to the correct value, and the network device A will change the result at the same time. Report the OMC system in real time, and apply for the OMC system to reclaim configuration rights. If the OMC system does not agree to transfer the configuration rights of the transmit power to the LMT system, it is necessary to notify the OMC system to modify the operation and maintenance personnel, which affects the efficiency of solving the problem.

Table 3 is the list of data stored in the filter after the LMT system requests the transfer configuration permission and its configuration permission information.

If the network device A needs to be configured with the environment monitoring threshold, the OMC system will automatically send the configuration permission of the environment monitoring threshold to the LMT system. However, the actual network device A needs to perform the board configuration. In this case, the LMT system applies for the board to the OMC system. Configuring the privilege, the OMC system agrees to the privilege of the configuration of the board in the LMT system. At this time, the configuration rights of the data stored in the filter are as shown in Table 4. The LMT system board is configured and the board configuration information is reported to the OMC. system. And apply for the OMC system to recover all configuration rights (single board configuration and environment monitoring threshold configuration) transferred to the LMT system.

Table 4 shows the data list and its configuration rights stored in the filter after the OMC system active transfer and LMT system request transfer configuration permission information.

Serial number configuration table information LMT system configuration permission switch 1 cell configuration 0

2 Board configuration 1

3 topology information configuration 0

4 Environmental monitoring threshold configuration 1

5 transmit power configuration 0

6 OMC port configuration 0

If the OMC system actively sends the configuration rights of the board configuration to the LMT system, the LMT system applies the right to configure the topology information to the OMC system. The LMT system performs the board configuration and topology information configuration operations, and reports the execution information. OMC system. However, the alarm on the interface that the transmit power of the board is too small appears. The LMT system does not have the right to transmit power configuration. Therefore, the OMC is requested to apply the transmit power configuration permission. If the OMC system agrees to transfer the power configuration permission to the LMT system, At this time, the configuration rights of the data stored in the filter are as shown in Table 5. The LMT system changes the transmit power and reports it to the OMC system. When the modified transmit power is correct, the alarm is cleared, the LMT system operation is completed, and the OMC system is reclaimed. Configuration rights transferred to the LMT system (board configuration, topology information configuration, and transmit power configuration). If the OMC system wants to modify the transmit power cancellation alarm itself, it does not agree to transfer the configuration rights to the LMT system. Then, the configuration of the LMT system has been completed. The OMC system is used to reclaim all the configuration rights (board configuration and topology information configuration) that are transferred to the LMT system.

Table 5 shows the data list and its configuration rights stored in the filter after the OMC system active transfer and the LMT system real-time request transfer configuration permission information.

The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.

Industrial applicability

As can be seen from the foregoing embodiment, compared with the prior art, the technical solution of the present invention connects the OMC system and the LMT system to the network device at the same time, and transfers the configuration authority to the LMT system through the OMC system to perform data on the network device. Configuration, at this time, the OMC system will not be able to configure the data of the transfer configuration permission, thereby ensuring that only one operation and maintenance system can operate the network device at any time, that is, while the OMC system and the LMT system share the network device data. , to ensure the mutual exclusion operation of the OMC system and the LMT system. In the process of configuring the privilege transfer, the configuration of the LMT system is reported to the OMC, and the operation of the LMT system can be monitored in real time and synchronized with the network device data. On the other hand, the data of the configuration authority (that is, the data that cannot be configured by the LMT system) that the OMC system has is written into the filter, that is, the configuration operation of the LMT system is filtered.
