Description

A method, system and device for dialing and testing remote services

technical field

The invention relates to the field of communication technology, in particular to a method, system and equipment for dialing and testing remote services. the

Background technique

The traditional WCDMA (Wideband Code Division Multiple Access) base station building process includes two steps: hardware installation and software commissioning. First, the hardware installation engineer completes the hardware installation of the base station, including the peripheral supporting facilities and Hardware installation of base station equipment. Among them, the installation content of peripheral supporting equipment of the base station includes: cabinet base or pole installation, cable installation, feeder cable installation, lightning arrester, antenna feeder installation, etc.; base station equipment installation content includes: cabinet installation, single board installation, wiring installation, etc. . the

Then, the soft-tuning engineer completes the software commissioning of the base station, checks the hardware installation status of the base station, and then powers on the base station to run. software upgrade or rollback. Then complete data configuration, cell status check, alarm check and elimination. In the software commissioning of the base station, operations such as software upgrade, data configuration, cell status check, alarm check and troubleshooting all need to be performed on a portable computer near the base station. After the soft-tuning engineer completes the base station software upgrade, data configuration and other operations, and checks that the cell status and single board status are normal, the service dial-up test is performed to ensure that the base station has no other problems and can provide services normally. the

During the software commissioning process of the base station, a test terminal or a commercial terminal (supporting engineering mode) is usually used for service dial-up test. During the dial-up test process, each cell of the base station needs to be traversed one by one (block other cells first, and only keep the dial-up test cell), and verify various service types (voice, video calls, streaming media, etc.) one by one. the

In the traditional base station construction, hardware installation and software commissioning are two independent steps. The hardware installation engineer completes the hardware installation of the base station. The near-end of the base station performs software commissioning operations such as software upgrade, data configuration, status check, and service dial-up test. After checking that the status of the base station is normal, the soft-tuning engineer starts the service dial-up test at the near end of the base station. Usually, the operation process of the service dial-up test is as follows: 

Step s101, use a portable computer to connect to the base station at the near end of the base station, block all other cells, and only keep one cell to be tested;

Step s102, open the test terminal, and set the frequency point and scrambling code of the terminal to be consistent with the cell to be tested;

Step s103, use the test terminal to make a voice call, and record the call situation (whether it is connected, whether it is dropped, etc.), repeat the call N times, and record the success rate;

Step s104, use the test terminal to make a video call, and record the call situation, repeat the call N times, and record the success rate;

Step s105, use the test terminal to test the business types required by other operators, and record the call situation, repeat dialing N times, and record the success rate;

Step s106, changing the cell to be dialed and tested, repeating steps s101 to s105, and completing the service dialing and testing of all cells in the base station one by one. the

In this solution, the dialing and testing process of the base station service is completely dependent on manual operations. It is necessary to repeatedly perform operations such as blocking or unblocking the cell, setting the frequency point and scrambling code of the terminal, and repeatedly dialing or hanging up the phone. The operation is inconvenient and time-consuming. It takes more than 20 minutes to complete the service dial-up test of a cell, and more than an hour to complete the service dial-up test of a 3×1 minimum configuration base station, and it is also prone to operational errors. the

In addition, in order to complete the software commissioning of the base station, soft-tuning engineers need to enter the base station site again for operation. Since the base station is usually distributed in a remote location, various expenses such as manpower and transportation need to be increased, which greatly increases the construction cost of the entire base station. . the

Because the traditional service dial-up test operation is complex and time-consuming, another alternative service loopback test solution was created to realize service verification. In the solution of service loopback test, it is not necessary to use the test terminal for real service dial-up test, but only need to use a portable computer to start the service loopback test function of the base station, generate service test data inside the base station, and set The loopback point loops back uplink and/or downlink service data, and the base station automatically judges whether the loopback service data is correct to determine whether the base station can provide services normally. the

The business loopback test scheme is adopted, because the test of the business loopback test cannot cover the service channel of the entire base station (it can only cover the service channel of the IUB interface and baseband processing, and cannot cover the radio frequency interface), so even if the service loopback test If no problem is found, there is no guarantee that the real terminal services will be normal. The service loopback test cannot fully meet the verification requirements of the service dial test. the

In summary, the inventor finds that the prior art has the following shortcoming in the process of realizing the present invention:

In the prior art service dial test solution, soft tuners are required to manually dial test at the near end of the base station, the manual operation is complicated, and the base station construction cost is high. the

Remote maintenance channel. The remote soft-tuning tool software performs a series of soft-tuning operations such as software upgrade, data configuration, cell and alarm check on the base station to be commissioned through the network management agent. After confirming that the status of the base station is normal, the remote soft-tuning tool software automatically controls the test terminal to dial by The hardware installation engineer carries it to the test terminal at the near end of the base station, and automatically blocks or unblocks the cells one by one to complete the service dial test of the entire base station.
