At the same time, we will actively introduce the good optimization methods of 2G into TD optimization, promote the integration and maintenance optimization of 23G networks, adhere to the optimization concept of "one network", build a boutique network, comprehensively carry out refined optimization of 2/3G networks, and improve the quality of TD networks in all directions. At the same time, the customer perception of TD network is implemented to achieve the excellent index of group assessment.

GSM/TD network optimization is long-term, based on network management KPI, according to daily TOPN problem cell tracking processing, wireless network sudden problem analysis processing, regular data consistency check and traffic balance, traffic data analysis, alarm statistics and analysis, KPI index optimization. Do a good job in daily indicators, weekly performance summary and statistics and problem handling,

Conduct monthly analysis, find problems from the changes of indicators in monthly analysis, and put forward rectification plans. Do a good job in early detection and fault pretreatment.

Second, the wireless network planning

Continue to focus on improving network coverage in urban areas, towns and new districts, and pay attention to input-output benefit analysis; Continue to adhere to the guiding spirit of "three principles of coverage optimization" to ensure the absolute leading edge of network coverage; Guided by customer perception, network satisfaction and user complaints, we will solve historical difficult sites through various means and ways, effectively improve network coverage and effectively take into account the interests of assessment and testing; Continuously follow up the overall planning of developing areas and newly developed areas, and implement base station construction in time to ensure that network development will not affect regional economic development; Strengthen the optimization of network three-dimensional planning, and carry out key planning and technical research on high-rise dense communities. Mainly around new fields such as new municipal venues, public facilities, new large-scale development zones and new commercial and residential areas; The areas where customer complaints are concentrated, especially the office buildings and commercial and residential areas with large complaints in urban areas, have weak coverage; Railway, high-speed and other important traffic trunk lines will follow up the construction of new GSM wireless network stations. While fully ensuring the quality of voice service, it further ensures the data network carrying capacity of the network, and ensures the bandwidth access capacity of the edge network through resource allocation. For areas with high traffic density, high base station distribution density and high frequency reuse rate, increase investment in 1800 equipment to improve network quality.

Combined with the actual situation of the existing network, the campus network construction planning idea of realizing TD+GSM+WLAN integration is planned in advance. TD planning should focus on ensuring continuous coverage of TD signals in counties, cities and core cities, and filling up weak coverage areas; According to the principle of TD coverage from the inside out, strengthen the construction of TD indoor coverage system; Expand the high data service area covered by TD, and focus on ensuring the data service support ability of TD; Make full use of the existing 2G site, remote site, indoor distribution and other resources, build * * * site as much as possible, and strive to increase the proportion of * * * stations.

Service-oriented data network planning fully meets the development needs of voice, video and data services. According to the general principle of "clear hierarchy, perfect function, standardize equipment and pay attention to actual effect", the network hierarchy is clear and the network structure is flat. User access can be flexibly selected according to different business requirements and different coverage areas. Comprehensively deepen the upgrading and transformation of data networks, expand the coverage of transformation, optimize configuration, and achieve the ability to surpass competitors.

Third, standardization and refinement of testing.

Test and analysis should be customer-oriented, test and analysis as the starting point, horizontal comparison as the reference, and positioning the problem as the goal, so as to do a good job in the diagnosis of "network problems".

Provincial and municipal companies cooperate to carry out daily test analysis, realize the standardization of daily test and improve the accuracy of test analysis.

All localities should make full use of the province's test data to optimize and avoid a large number of repeated tests and the precipitation of massive data. Test and analyze the quality of wireless networks, border networks and competitors, and provide decision data for wireless network planning and quality management.

Do a good job in daily optimization test and strengthen the management of automatic road test. The report of automatic road test must be analyzed by a special person, and the corresponding problem analysis and processing flow must be established. Every problem found by the automatic road test system must have a processing result. Taking the automatic drive test system as the starting point to monitor the quality of 2G network, this paper focuses on analyzing the customer perception indicators of all cities in the province, and pays close attention to the operation quality of 2G network.

Strengthen the normalization of high-speed, high-speed rail and urban 2G/TD testing, provide accurate and effective problem-solving solutions with the goal of finding and locating problems, and comprehensively improve network quality.

Fourth, platform construction informationization.

At present, there are many platforms in the province, so it is necessary to make full use of network optimization platform, WPM, ASPS and CDR to continuously carry out optimization work.

The platform is close to use, updated in real time and accurate in data. Multi-platform related applications are integrated. Through the use of the platform, the experience resources of network optimization are solidified, and intelligent automatic analysis and case sharing are realized. Promote the application of the platform in various ways, constantly improve the system in the application, form a virtuous circle of application and development, and improve the analysis ability of the network optimization platform. In the later stage, we can make full use of and deeply relate to the following data sources: short call ticket, complaint, alarm, signaling platform, CHR, short message platform and performance statistics, quickly locate and reproduce network difficult problems, explore a comprehensive early warning system that can comprehensively and objectively describe users' perception of network operation (alarm), performance (KPI) and signaling (event trigger), and solidify it into a network optimization platform.
