The necessity for wireless network maintenance

In wireless network management, wireless network maintenance and wireless network optimization are very important and need rich experience. This is an essential task for wireless network competition. Therefore, better network performance will inevitably attract a large number of users. Therefore, management and maintenance cannot be relaxed at all. This article will introduce you in detail.

How can we improve network service quality and enhance competitiveness? In my opinion, basic maintenance must be strengthened to ensure that the equipment is in good condition, and the network must be constantly optimized to improve service quality ｡

I. Division of wireless network maintenance work

The wireless network maintenance work can be divided into two parts according to the different nature of work: basic maintenance and network optimization ｡

Basic Maintenance refers to the routine maintenance and inspection of the wireless network main equipment and its supporting equipment in accordance with the maintenance regulations of the mobile communication network, this includes cleaning up equipment and data room environmental sanitation, as well as equipment repair and emergency response. The main purpose is to detect equipment problems early through routine wireless network maintenance, eliminate faults, and ensure that the equipment is in good condition ｡

Network optimization is based on the intact equipment, with the help of testing tools and analysis software, the optimal combination can be achieved through adjustment of network parameters such as site location, carrier frequency configuration, antenna height, pitch angle, azimuth angle, relay configuration, and BSC database settings, high-level wireless network maintenance to improve network service quality and enhance network competitiveness is a key part of wireless network maintenance ｡

2. Basic wireless network maintenance is the foundation of network maintenance and the prerequisite and guarantee for achieving good network service quality.

Any device is affected by a variety of environmental factors from the first day of activation. for mobile communication devices, factors that affect the normal operation of devices can be divided into external and internal factors, external factors include power supply, transmission, room temperature, humidity, dust, water, fire, thunder, and theft; internal factors include aging of equipment components, software faults, and parameter settings, many factors lead to exposure or latent faults along with the operation of equipment. Basic wireless network maintenance should not only eliminate faults, but also eliminate potential risks and prevent faults, as the saying goes, "preventing problems before they happen". It can be seen that basic maintenance is the top priority of the maintenance work ｡

1. Basic maintenance is the fundamental guarantee for Device integrity

Basic maintenance can be classified into network troubleshooting and daily maintenance based on the nature of the work ｡

Network Clearing refers to the centralized handling of online problems, mainly due to problems left over by engineering construction and network cutover, updating equipment archives and materials to provide daily maintenance and network optimization services ｡

Engineering Construction will change network parameters, and engineering planning may not fully reflect the changing network environment; Module defects, incompatibility between software and hardware versions, and subtle issues of wireless planning, network communication quality is affected. Therefore, after major engineering or network changes, network troubleshooting needs to be promptly cleared, network parameters should be properly adjusted, and equipment archives should be improved ｡

Routine wireless network maintenance refers to the inspection of each device according to different detection items and cycles, to improve the operation environment of the equipment, as well as to discover hidden dangers and repair the equipment, in order to detect problems in time, shorten the fault time, avoid major communication accidents, and effectively keep the equipment intact ｡

2. Basic wireless network maintenance is the basis for Network Optimization

Any network optimization work must be based on the integrity of the device, because the adjustment of network parameters must conform to the actual network conditions, and the network optimization adjustments should be made when the integrity of the device is not ideal, even if the network indicators can reach a high level, the network service quality has been greatly improved. However, after the equipment fault is eliminated and the integrity rate is improved, can the well-adjusted parameters still meet the network status quo, the optimization work will be abandoned ｡

3. Basic wireless network maintenance is an important part of maintaining network optimization results

Through network optimization, various parameters are adjusted to the optimal state, and the network service quality is naturally greatly improved. If the equipment is in good condition, the optimization results will be at a loss ｡

The mobile communication network of Anhui mobile has developed to the current level. The switching relationship between residential areas and the network structure are complex, and the frequency reuse is more compact, to a greater extent, the quality of the wireless network depends on the Integrity Rate of the base station equipment. The carrier frequency failure of the base station changes the frequency reuse relationship, destroys the normal switching order, and generates interference in the system, affecting the voice quality, this causes TCH disconnection and congestion, which results in unbalanced traffic distribution and seriously affects the quality of wireless network services. This is the comparison of various network indicators of Hefei BSC1 before and after the occurrence of a fault on the lu'an Road Base Station, the Network indexes of base stations in urban areas depend on the well-equipped devices. Therefore, excellent optimization results must be guaranteed by excellent basic wireless network maintenance to provide a high-quality wireless network perfectly ｡
