Remote image of wireless base station

Method, device and system for monitoring

The present invention relates to the teaching field of operation and maintenance of base station equipment in a mobile communication system, and in particular, to a method, device, and system for remotely monitoring base station equipment in a mobile communication system. Background technique

In mobile communication systems, base station equipment is distributed over a wide geographical range, and antenna units are erected on the roof or iron tower of high-rise buildings. Many base station equipment are also installed outdoors. The remote geographical location makes actual site maintenance more difficult, and the outdoor environment is greatly affected by natural and human factors. Therefore, it is particularly important to effectively monitor the operating conditions of base station equipment.

In the prior art of wireless base station equipment operation and maintenance, circuit detection methods are used for the working conditions of the base station equipment boards, such as overvoltage, overcurrent, overload, out of step, and abnormal operation, etc., to the environment of the base station equipment itself. , Specific sensors such as temperature sensors, humidity sensors, door switches, pyrotechnic sensors, etc. are used for measurement or detection. All this information is processed by the local monitoring unit of the base station to form eye-catching measured values or alarm information, which is transmitted to the operation and maintenance center via the communication link between the base station and the base station controller. However, none of these detection information can directly reflect the surrounding environment of the base station equipment itself. When some of the above-mentioned warning information appears, due to the lack of direct observation of the base station equipment and the environment in which the base station is located, system maintenance personnel often cannot accurately judge the occurrence of the alarm Information, and therefore cannot be effectively processed.

At the same time, in the mobile communication system, changes in the direction of the base station antenna, the downtilt angle, and the surrounding environment have a great impact on the coverage of the community. Due to the imperfect engineering installation, and artificial or natural factors such as wind or rain or snow after installation The effect of the antenna The direction and downtilt angle will change to change the cell coverage. In addition, due to changes in the surrounding propagation environment caused by urban construction, buildings that are not available during base station survey and construction will affect the coverage of existing base stations. In the actual operation of the system, engineers often can only find cell coverage or performance problems through analysis of drive test data or system performance statistics, and then passively go to the site where the base station is erected to conduct on-site investigations to find problems and make adjustments. This will undoubtedly have a long-term impact on performance such as network coverage and increase the maintenance cost of base station equipment.

In addition, base station equipment, especially base station equipment that supports multi-sector and multi-carrier, is expensive.
