Description

System and method for performing maintenance testing on a wireless system

Technical field

The present invention relates to the field of communications, and in particular, to a system and method for performing maintenance testing on a wireless system.

Background of the invention

With the rapid growth of mobile users, there are more and more problems in the operation of wireless systems. This is mainly

'Because communication equipment, especially access layer equipment, is often quite complex, wireless system networks are large in scale and numerous in equipment. Protocol specifications are very complex, and there are differences in interconnection between multi-vendor devices. In order to solve the above problems, it is very important to perform maintenance tests on wireless systems and wireless communication devices (including wireless base stations, wireless terminals, etc.).

Maintenance testing and fault demarcation of communication equipment (including central office equipment and customer premises equipment) is an important means to ensure the stable operation of communication equipment. This maintenance test and fault demarcation function is often done through a maintenance test system. The maintenance test system must perform maintenance test, fault demarcation and even positioning work on the basis of the original function of the communication device, so as to quickly find out the faulty module in the communication device, so as to ensure that the maintenance personnel can replace it in time. Or repair the faulty module to ensure the normal operation of the communication equipment.

The existing broadband equipment maintenance test system is mainly designed for wired access technology, such as ADSL (Asymmetric Digital Subscriber Line) access technology. The principle of its maintenance test is to first delimit the fault and then locate the fault. Based on the results of the fault location, the faulty module can be quickly identified.

Take ADSL as a wired access technology as an example. The commonly used fault demarcation methods are as follows:

1. Outside line test (Test-out);

2, internal test (Test-in);

3. Terminal simulation (CPE simulation);

4. Central office simulation (CO simulation).

The commonly used fault location methods are as follows -

1, SELT (single-ended test);

2, DELT (double-ended test);

3, Loop Back (loopback test);

4. Test the line with external test instruments or modules.

In order to achieve the above-mentioned fault demarcation and fault location functions, the corresponding test module and test access module must be added in the DSLAM (Digital Subscriber Line Access Multiplexer) system. As shown in Figure 1. In the maintenance test system of the DSLAM system shown in Figure 1, the following test schemes are included:

1. Test the access module connection 1 and 4 points, as shown in Figure 1. The central office equipment is connected to the user terminal equipment, DSLAM The system is in normal working condition.

2. Test the access module connection 1, 2 and 2 points, as shown in Figure 2. The user interface card is connected to the internal measurement unit, and the internal measurement unit tests the user interface card and its upper module through the internal test bus.

3. Test the access module connection 3, 4 two points, as shown in Figure 3. The user terminal device is connected to the external measuring unit, and the external measuring unit tests the user terminal device and the user line outside line through the external measuring bus.

4. Test the access module at the same time when connecting 1, 2, and 3, 4 points, as shown in Figure 4. The user interface card is connected to the internal measurement unit, and the user terminal device is connected to the external measurement unit. The internal measurement unit tests the user interface card and the upper layer module through the internal test bus, and the external measurement unit passes the external measurement bus to the user terminal device and the user line. The outside line is tested.

The disadvantages of the maintenance test system shown in Figure 1 are: The system can only be used for wired access technologies, such as ADSL access technology, and cannot be applied to the wireless access field.

An existing test and maintenance method for a wireless access system is: performing a case test on a wireless access system and equipment through a handheld or portable test device.

The disadvantage of this method is that the handheld or portable test device has no correlation with the wireless base station or the terminal itself, and therefore cannot effectively delimit and locate the wireless access system and the device, and cannot be based on the test result.

Access Point Unit: This unit can be independent of the base station, outside the base station, or built into the base station. Access to the test signal sent from the test unit is completed. For a base station, the access points can be one, two or more.

The specific location of the access point can be selected according to the actual situation. For example, it can be selected between IDU (indoor unit) and 0DU (outdoor unit).

As shown in FIG. 6, in the test system shown in FIG. 6, the test access module (access point) is in the form of a switch, and the connection between the test module and the IDU or the test module and the 0DU is turned on.

When the access point connects the two points 1 and 2 in Figure 6, when the test module (ie, the test unit) is turned on with the IDU, the internal test unit in the test module (that is, one subtest unit in the test module) can Complete testing of the IDU and its upper module (or device).

The specific location of the access point can also be selected between the outdoor unit and the antenna. As shown in Figure 7.

In the test system shown in Figure 7, the test access module (access point) is in the form of a switch that turns on the connection between the test module and the 0DU or the test module and the antenna.

When the access point connects the two points 1 and 2 in Figure 7, when the test module is connected to the 0DU, the internal test unit in the test module can complete the test of the 0DU and its upper module (or device).

When the access point connects the two points 1, 2, 3, and 4 in Figure 7, at the same time, when the test module is turned on simultaneously with the 0DU and the antenna, the internal test unit in the test module completes the 0DU and its upper module ( Or the test of the device, the external test unit in the test module completes the test of the antenna and its underlying modules (or devices).

Of course, you can also select two test access points at the same time, that is, between the IDU and the 0DU, and between the 0DU and the antenna. 48 Set up an access point. As shown in Figure 8.

In the test system shown in Fig. 8, the test module 1 and the test module 2 can work independently or simultaneously, and the internal test unit and the external test unit in the test module can also work independently or simultaneously. The test access module 1 can control the connection of two points of 1, 2 and 3, 4, and the test access module 2 can control the connection of two points of 5, 6 and 7 and 8. Therefore, by combining the test module 1, the test access module 1, and the test module 2, the test access module 2, there are many test scenarios.

For example, the test access module 1 connects the two points 1 and 2 in FIG. 8 , that is, the test module 1 is connected to the IDU, and the test access module 2 connects the two points 5 and 6 in FIG. 8 , that is, the test module 2 and the 0DU guide. through. Then, the internal test unit in the test module 1 can complete the test of the IDU and its upper module (or device), and the internal test unit in the test module 2 can complete the test of the 0DU.

Test the access module 1 Connect the two points 1 and 2 in Figure 8. The test module 1 is connected to the IDU. The test access module 2 connects the two points 7 and 8 in Figure 8, that is, the test module 2 is connected to the antenna. Then, the internal test unit in the test module 1 can complete the test of the IDU and its upper module (or device), and the external test unit in the test module 2 completes the test of the antenna and its lower module (or device).

Through the various test schemes described above, the radio base station analysis unit can control the test module to perform segmentation test on the base station, and perform fault delimitation for the base station according to the data obtained by the specific test returned by each test module. If the result reported by the wireless terminal analyzing unit is matched at the same time, the wireless base station analyzing unit may perform fault demarcation and even positioning on the wireless access link including the base station and the terminal.

In the system of the present invention shown in FIG. 5, the wireless base station and the wireless terminal can be tested according to two logical links at the same time, as shown in FIG. 9, including the logical link 1 for testing the wireless base station, for wireless Logical link 2 for the terminal to test. The two logical links can be performed simultaneously or independently and independently.

According to logical link 1, the test includes the following process -

1 - 1. The wireless base station test unit initiates a test command to the test access module (access point);

1-2. The test access module accesses the test module to the base station according to the test instruction;

1-3. The test module tests the base station according to the test instruction;

1-4. After the test module is tested, the test data is returned to the test unit of the wireless base station, and at the same time, the test access module releases the test line, and the base station resumes normal operation;

1 - 5, the wireless base station test unit analyzes the received test data and outputs the analysis result.

The logical link 1 is for the base station. Of course, in the specific test process, the wireless terminal also needs to cooperate accordingly. For example, the loopback test on the terminal side. However, the entire logical link 1 test process does not require the participation of the wireless terminal test unit. 06 001648 According to Logical Link 2, the test includes the following process:

2-1. The wireless terminal test unit initiates a test instruction to the wireless terminal;

2 - 2. The wireless terminal performs the test according to the received test command;

At this point, the wireless terminal can select two test data return mechanisms, one return mechanism is to return the test data to the wireless terminal test unit, as shown in Figure 9, logical link 3, in this case - 2-3, wireless terminal Returning the test data to the wireless terminal test unit;

2-4. The wireless terminal test unit analyzes the received test data and outputs the analysis result.

Another return mechanism is to return the test data to the radio base station test unit, as shown in the above figure, the logical link 4, in this case - 2-5, the wireless terminal returns the test data to the radio base station test unit;

2-6. The wireless base station test unit analyzes the received test data and outputs the analysis result.

When the logical link 1 described above exists independently. That is to say, when the wireless terminal test unit does not test the wireless terminal, the system of the present invention shown in FIG. 5 performs only the test flow of 1-1 to 1-5.

According to the test flow of logical link 1 and logical link 2 described above, faults occurring in the wireless access system (including the base station system and the wireless terminal) can be delimited. For example, as shown in FIG. 7, when the access point is located between the 0DU and the antenna, the specific process of the fault demarcation of the system of the present invention is as shown in FIG. 10, and the specific description is as follows: at the beginning of the test, the radio base station test unit The control test module performs an internal line test on the wireless base station, and analyzes the test result according to the test data returned by the test module. If the test result is abnormal, the outdoor unit of the wireless base station and the upper layer module thereof are abnormal, and at this time, the wireless device can continue to The base station performs the external line test, and can also stop the test and solve the fault. If the test result is normal, the external line test of the wireless base station is continued.

The wireless base station test unit analyzes the test result according to the external line test data returned by the test module. If the test result is normal, the wireless access system (including the base station system and the wireless terminal) works normally; if the test result is abnormal, the wireless base station is illustrated The antenna and its underlying device are abnormal. At this time, the wireless terminal test unit can continue to test the wireless terminal, and analyze the test result according to the test data returned by the wireless terminal. If the test result is normal, the wireless terminal works normally, and the wireless terminal The antenna or related device of the base station is abnormal. If the test result is abnormal, the wireless terminal is abnormal.

The internal and external tests described above can be performed in a number of different test points, that is, segmentation tests can be performed within the system to achieve finer segmentation fault demarcation. A schematic diagram of this segmentation test is shown in Figure 11.

In Figure 11, through different access points, we can logically divide the wireless system into multiple locales. In Each access point test completes the segmentation test for each zone, thereby narrowing down the faults hidden at a certain point in the system to a certain interval. Figure 11 divides the wireless system (including the base station and the terminal) into four segments through two test access points: upper device, interval 1, interval 2, and terminal device. Through the fault demarcation process shown in FIG. 12, a certain point fault in the system can be located in a certain segment of the above four segments.

The segmentation test fault demarcation process shown in Figure 12 is not unique. The interval division method and test sequence can be adjusted accordingly according to the actual situation.

In practical applications, the system of the present invention can perform dimensional analysis analysis work on multiple base stations at the same time. As shown in FIG. 13, a wireless base station analysis unit controls a plurality of test modules, and performs quality measurement management and test analysis on N base stations. In this case, the radio base station analysis unit may be designed and installed on the same hardware platform as the network management system; of course, it may exist independently of the network management system.

The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or within the technical scope disclosed by the present invention. Alternatives are intended to be covered by the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
