In addition, if there are several private exchange failures to be notified to the same private exchange maintenance personnel, the system 100 will notify the private exchange maintenance personnel of the obstacles one by one in order of the user levels related to the obstacles.

The present invention proposes a method for supporting application services of automatic failure detection and notification of private branch exchanges, including a method 300 of automatic failure detection and notification service management of private branch exchanges, a method 400 of outbound dial detection and notification of private branch exchanges, and a method 400 of private branch exchange dial-out detection and notification. The method of entry detection and notification 500 is described in detail below.

Please refer to the flow chart of the method 300 for automatic failure detection and notification service management of a private branch exchange shown in Figure 3. The steps are detailed as follows.

In step 310, the user verifies the identity through the web interface provided by the service management module 110. If the authentication fails, the user is directly refused to log in; otherwise, if the authentication passes, the user's identity is determined in step 315. The user's identity can be divided into There are two types of automatic fault detection and notification of private exchanges: service managers and private exchange maintenance personnel.

If it is a private branch exchange automatic fault detection and notification service manager, in step 320, at least one of the following operations can be performed:

1. Add, delete, query, and modify the account and password of the maintenance personnel of each dedicated exchange.

2. Add, delete, query, and modify the monitoring configuration files of each private exchange.

3. Query and delete the monitoring records of each dedicated exchange.

4. Add, delete, query, and modify the monitoring schedule of each dedicated exchange, and reschedule the changed monitoring schedule in the scheduling and configuration analysis function module 130.

If you are a private switch maintenance personnel, in step 330, you can perform at least one of the following operations:

1. Add, delete, query, and modify your account and password.

2. Add, delete, query, and modify the monitoring configuration profiles of the private exchanges it manages.

3. Query and delete the monitoring records of the private exchanges it manages.

4. Add, delete, query, and modify the monitoring schedule of the private exchanges it manages, and update the changes after The monitoring schedule is rescheduled in the scheduling and configuration analysis function module 130 .

The above-mentioned monitoring schedule can, for example, be set to activate a specific monitoring configuration profile at a specific time and/or a specific period, so as to activate the dedicated switch corresponding to the specific monitoring configuration profile according to the specific time and/or the specific period. Automatic obstacle detection.

Please refer to the method 400 of detecting and reporting outbound calls of a private branch exchange shown in Figure 4. The steps are detailed as follows.

In step 410, the scheduling and configuration analysis function module 130 starts outbound dial detection on time according to the private branch exchange monitoring schedule.

In step 420, the scheduling and configuration analysis function module 130 reads the monitoring configuration profile of the representative number of the private exchange from the database 120, parses the monitoring configuration profile, generates the corresponding test script, and then writes the test script Sent to the call monitoring and alarm notification functional module 140, so that the call monitoring and alarm notification functional module 140 executes steps 430 to 470. The content of the above test script is essentially the same as the monitoring configuration configuration file, but the format is different.

Next, in step 430, an outbound call is initiated to the representative number of the private branch exchange, and then in step 435, the status of the call result is checked. If the status of the call result is Error, then in step 460 the test result is recorded as Impediment.

If the status of the call result is answered, then in step 450, the private branch exchange test program is executed one by one according to the test script. During the execution of the private exchange test program, if an obstacle is found, the private exchange test program is interrupted, and the test result is recorded as an obstacle in step 460; conversely, if no obstacle is found during the execution of the private exchange test program, then in step 460 Step 460 records the test result as normal.

If the status of the call result is busy or no response, then in step 440, it is checked whether the number of outbound calls in step 430 has exceeded the threshold. If the number of outbound calls has not exceeded the threshold, then return to step 430 to start the next outbound call. Make a call; otherwise, if the number of times exceeds the threshold, the test result is recorded as an obstacle in step 460.

Next, in step 465, check whether the test result recorded in step 460 is normal or faulty. If the test result is normal, the process of method 400 ends; otherwise, if the test result is faulty, in step 470, according to Monitor the notification method set in the configuration configuration file, notify the dedicated switch maintenance personnel and inform the possible cause of the failure, and then end the process of method 400.

Please refer to the method 500 of private branch exchange dial-in detection and notification shown in Figure 5. The steps are detailed as follows.

In step 510, the scheduling and configuration analysis function module 130 starts dial-in detection on time according to the private branch exchange monitoring schedule.

In step 520, the scheduling and configuration analysis function module 130 reads the monitoring configuration configuration file of the representative number of the private exchange from the database 120, and after analyzing the monitoring configuration configuration file, generates the corresponding test script, and then sends the test script to the call monitoring and alarm notification functional module 140, so that the call monitoring and alarm notification functional module 140 executes steps 530 to 550.

Then, in step 530, start the dial-in detection and wait for the dial-in report of the representative number of the private branch exchange. If the representative number of the private branch exchange dials in within the predetermined time period, the report is successful, and the process proceeds to step 540 for recording. The test result is normal; otherwise, if the representative number of the private branch exchange is not dialed in within the predetermined time period, the registration fails, and the process proceeds to step 540 to record the test result as failure.

Next, in step 545, check whether the test result recorded in step 540 is normal or has an obstacle. If the test result is normal, the process of the method 500 ends; otherwise, if the test result is an obstacle, in step 550, according to Monitor the notification method set in the configuration configuration file, notify the dedicated switch maintenance personnel and inform the possible cause of the failure, and then end the process of method 500.

Taking the private branch exchange A applying for the outbound dial detection and reporting service of the present invention as an example, assuming that the user dials a call to the private branch exchange A, he will hear the welcome message "Hello, Chunghwa Telecom, please dial the extension number directly, or press 9 to call the switchboard." ”, the maintenance personnel C first logs in to the service management webpage provided by the service management module 110 and sets the following parameters to generate the following monitoring configuration configuration file:

Private exchange representative number: 0412345678;

Monitoring schedule: start outbound call detection at 7:00 every morning;

Private exchange test procedure 1: default basic test procedure;

Private exchange test program 2: speech recognition test program; matching sentence: Hello, Chunghwa Telecom;

Notification method for private exchange maintenance personnel: Telephone (0912345678).

After the setting is completed, at 7:00 every morning, the invention will automatically dial the representative number of the private branch exchange 0412345678, and first execute the basic test program to detect common obstacles such as external line disconnection and dedicated line disconnection. If an obstacle is detected, the system will record the cause of the obstacle and dial 0912345678. Call maintenance personnel C and use speech synthesis to inform private branch exchange A of the cause of the failure. If the basic test procedure is passed, after private branch exchange A responds, it will continue to execute the speech recognition test program, and use the speech recognition function to match the welcome message of private branch exchange A with the matching sentence "Hello Chunghwa Telecom" set in the monitoring configuration profile. Make a match. If the match is successful, the test is passed. Otherwise, it will be deemed that there is an obstacle in private branch exchange A. The system will record the cause of the obstacle, call 0912345678 to maintenance personnel C, and use speech synthesis to inform private exchange A when the welcome message is broadcast. There are obstacles.

Take private branch exchange B applying for the dial-in detection and reporting service of the present invention as an example. Assume that private branch exchange B has a scheduled outbound dialing function, and the dial-in reporting service representative number of the present invention is 0487654321, and its maintenance personnel C logs in first. The service management web page provided by the service management module 110 sets the following parameters to generate the following monitoring configuration configuration file:

Private exchange representative number: 0487654321;

Monitoring schedule: start dial-in detection from 6:58 to 7:02 every morning;

Notification method for private exchange maintenance personnel: Telephone (0912345678).

After the setting is completed, private branch exchange B automatically dials 0487654321 at 7:00 every morning. If the report is successful within the predetermined time period (6:58~7:02), private branch exchange B has successfully passed the test. Otherwise, private branch exchange B will be deemed to have failed. If there is an obstacle, the system will record the cause of the obstacle, dial 0912345678 to maintenance personnel C, and use speech synthesis to inform the private branch exchange that B has not checked in on time.

In one embodiment, the present invention provides a computer-readable medium, such as a memory, a floppy disk, an optical disk or a hard disk. The computer-readable medium stores instructions that can be applied to telecommunications equipment, computing devices or computers to execute the above-mentioned method of automatic failure detection and notification of private branch exchanges.

Once completed, enterprise private switch monitoring services can be provided.

Third, the service management module of the present invention provides monitoring configuration profile setting and scheduling functions. Private switch maintenance personnel can set the private switch test script through the monitoring configuration profile. After completing the settings, the present invention will perform the monitoring according to the schedule. Start the monitoring configuration profile to perform automatic obstacle detection and notification of the private branch exchange.

Fourth, the present invention uses voice recognition technology and dual-tone multi-frequency receiving and sending functions to interact with the private branch exchange. Therefore, the private branch exchange at the end of the test does not need to be equipped with additional customized terminal equipment and does not need to set up detour routes in order to detect. If there are common obstacles such as no response, external line abnormality, dedicated line disconnection, etc., you can also use the private branch exchange's welcome message or prompt tone to further confirm whether the private branch exchange is operating normally. In addition, the private branch exchange itself can report by voice. Customer anomalies can also be detected and reported.

Fifth, the present invention can support the function of receiving a specific dual tone multi-frequency sequence after the representative number or sub-number of the private branch exchange responds. If the system does not receive the specific dual tone multi-frequency sequence when dialing for testing, it will be regarded as the private branch exchange to be tested. In the event of an obstruction, this feature can be used to periodically interrogate the private exchange to confirm its operational status.

Sixth, the present invention supports the function of the private branch exchange end dialing out to the service representative number of the present invention to report regularly. If the private branch exchange to be tested does not call to report within a predetermined time period, it will be regarded as that the private branch exchange may have a problem.

Seventh, when a private branch exchange failure is detected, the present invention will make an outbound call or notify the maintenance personnel of the private branch exchange via SMS or email according to the settings in the monitoring configuration file, and inform the possible cause of the failure. For the same dedicated switch maintenance personnel, if there are several dedicated switch failures to be notified, the system will notify the dedicated switch maintenance personnel one by one in order of user level.
