With the vigorous development of the global communication industry and the continuous improvement of my country's economic level, the development of cities and network operators is like a broken bamboo, the amount of urban public information data continues to expand, and the communication tariffs across the country are also rapidly falling, resulting in continuous access to the mobile communication industry. Increase [1,2]. The use of brand-new mobile network technology to realize the rational mining and analysis of smart city public information data has important practical significance.
At present, in the context of the rapid development of mobile Internet services, mobile edge computing (MEC), as one of the core technologies of 5G, has broad development prospects. MEC migrates computing storage capabilities and business service capabilities to the edge of the network, enabling applications, services, and content to achieve localized, short-distance and distributed deployment . The construction of a smart city is in a process from concept to gradual implementation. In a variety of smart city application scenarios, from intelligent transportation and autonomous driving to real-time monitoring and real-time monitoring, various types of data need to be processed at the edge of the network, not in the cloud. Therefore, edge computing plays an important role in a variety of smart city application scenarios. With reference to the Internet of Things and cloud computing industries, the potential market size of edge computing is expected to reach more than tens of billions. Based on the above market prospects and challenges, build a smart city video network service platform based on mobile edge computing technology, support the video network platform wireless camera access, process and distribute video data nearby, and improve the processing efficiency and service quality of the platform. The urban operation ecology provides a platform for co-creation and sharing, supports the sustainable development of smart cities, and provides support for public safety, comprehensive governance, urban management, and people's livelihood services.
After years of development, the GSM global mobile network has been relatively mature. Compared with the traditional network, its biggest advantage is the open interface, which is not limited to the air interface [4,5]. The GSM network has the advantage that the number of users with existing resources is as high as the high network coverage rate, and can well realize the long-distance transmission of data. The GSM network has more prominent advantages in short messages, including the obvious advantages of no dialing, permanent online, and wide coverage. This advantage is especially suitable for frequent transmission of small-flow data. This advantage can be used to set up communication lines in remote and economically underdeveloped areas, and through the use of GSM networks, unlimited charging and remote target monitoring can be achieved . The GSM network can also be used in automatic receivers and bank ATM machines. In addition, because the GSM network can realize the advantages of automatic identification of network parameters, it is often used to detect the position signal strength of certain working base stations. There are also significant advantages in positioning, and it is often used to measure the temperature of the positioning point.
At the advanced academic exchange meeting in November 2013, the concept of “smart city public information integrated platform” was proposed for the first time. This concept specifically clarified the technical system of the smart city public information integrated platform. Hot discussion and unanimous praise. This article will use the GSM network to realize the technical system and system architecture of the “Integrated Platform for Mining and Analysis of Public Information in Smart Cities”. According to the plan of the Ministry of Industry and Information Technology, a comprehensive platform for the mining and analysis of smart city public information has been proposed. Since 2015, the role of e-government in promoting the transformation of government functions and the construction of service-oriented government has become more significant, and has formed a national e-government transmission backbone network. The basic unified e-government network. The platform covers more than 85 percent of the important information of the central ministries and provincial government departments, and the coverage rate of the government affairs departments in prefecture-level cities and counties reaches 70%. And more than fifty percent. With the expansion of e-government services to the grassroots level, the role of mobile networks has become more popular, and a framework for public information platforms and business collaboration has basically taken shape. This framework includes a number of major businesses such as social credit, comprehensive taxation, market supervision, and social security.. According to the aforementioned national policy plans, the task of comprehensively deepening the construction of a smart city public information mining and analysis platform is put on the agenda. The goal is to systematically plan and improve urban public information, optimize information processing capabilities, and improve public service quality.

The optimization of the GSM network specifically refers to the use of various index thresholds and past experience to adjust the hardware equipment and parameters of the GSM network. Use the best technical capabilities to make full use of network resources to achieve optimal system performance, seek a balance between network resources and network quality, and optimize the relevant performance index parameters to maximize the network's service capabilities. Traditional networks are unreasonably designed in the construction of some smart cities, failing to achieve full coverage, causing weak signals at the edge of some areas to be dropped; in addition, unreasonable network parameter settings in areas will affect user switching and reselection. These are all It needs to be adjusted gradually in the process of network optimization. Wireless network optimization is the advanced maintenance work after network planning and project construction. From the preliminary planning of the base station to the completion of construction, the parameter configuration is set according to the preliminary planning or default settings. In this way, there will inevitably exist uncertain factors that require network optimization after the device enters the network. As an important work process of wireless network maintenance, wireless network optimization is different from network planning and construction, but it is inseparable from it. Therefore, the best way to improve network performance and service quality is to perform continuous technical optimization of the network on a regular basis.
