Imagine what people’s lives will be like in 20 years!

1. Key analysis of network optimization

At present, there are many tools for network optimization. Optimization engineers use different tools for different technical categories. Existing third-party optimization tools include: drive test data analysis software, frequency planning and optimization software, signaling analysis software, traffic statistics data processing software, GIS-based configuration analysis software, call order analysis, traffic and signaling load Flow forecasting software. Although these tools bring great convenience to network optimization engineers to complete their optimization work, because they often only target one (some) specific areas in the network optimization process, the optimization solutions obtained are obviously not optimal. Combining these The output of the tool is jointly analyzed with the output of the OMC system. The workload is still a human sea tactic and belongs to the extensive stage.

Network optimization is a process that involves the entire network or a local network and has a fixed life cycle (referred to as the optimization cycle). Generally speaking: the first is the data collection stage, which consumes a lot of manpower to output various tools. The data is routinely sorted; then comes the data analysis stage, in which the optimization engineer conducts comprehensive analysis and judgment on the problems or situations reflected in the sorted data, and finally forms an optimization and adjustment plan involving network elements at different locations and levels; and finally In the implementation phase, the network adjustment operations determined in the adjustment plan are implemented; in the evaluation phase, data collection is carried out again to observe whether the adjustment plan has achieved the effect. If the expected effect is not achieved, the whole process is repeated again. If the effect is achieved, set up again. Set new, higher optimization goals, and the entire process will be repeated again at a higher level. In the entire life cycle of optimization work, the data analysis phase is the most difficult, and the collection phase, implementation phase and evaluation phase have the largest workload. In order to free optimizers from the collection phase, implementation phase and evaluation phase, which have the largest workload but relatively low difficulty, "integrated processing and simple analysis" software should be the best choice. The characteristics that this type of software should have are:

1) Support tables, graphics and text as expression methods;

2) Quickly switch between expression methods;

3) Customer secondary development functions (customized) in the most expressive manner;

4) Unified format storage of third-party software and OMC system data;

2. Network Optimization methods are developing towards intelligence and automation

Network optimization is a long-term process that runs through the entire process of network development. Network optimization comprehensively analyzes the entire communication network through parameter collection, statistical data analysis, signaling tracking, drive test information collection and analysis, etc. to identify network problems and adjusts the software and hardware configuration of the network to make the entire network achieve The optimal situation enables efficient use of limited resources.

With the further development of network optimization work, network optimization tools and methods continue to develop towards the ideas and technologies of artificial intelligence and expert systems. Many network analysis, planning, and optimization software have emerged. By introducing intelligent decision-making Support the system, establish a reasonable wireless network optimization knowledge base, and use effective reasoning mechanisms to provide appropriate problem solution suggestions to network optimizers for certain operation and service quality problems in the network. It can also provide suggestions for the given solutions. Conduct necessary data analysis on the plan and make corresponding explanations.

In addition, the automatic drive test system used by operators to proactively understand user experience has automated and intelligentized the traditional simple and repetitive drive test work. Through statistical analysis of massive data, the overall performance of the wireless network can be more accurately and objectively reflected on the geographical analysis platform, providing necessary support for wireless network monitoring and optimization work.

Therefore, we need to rationally and effectively use the newly developed network optimization software, integrate network information more effectively, continuously accumulate network optimization experience, and make network optimization work industrialized and routine, so as to provide users with Premium mobile network.

3. Network optimization work should be combined with 3G network planning work

It is imperative to smoothly evolve the current network to a 3G network. Therefore, network optimization personnel should learn in advance 3G knowledge, understand the characteristics of next-generation networks, accumulate 3G network experience of foreign operators, and prepare knowledge and technical reserves for developing and optimizing 3G networks. In the optimization work of the existing network, basic data of the existing network should be collected in advance, the structure of the next-generation network should be reasonably predicted, and the 3G network should be planned in a reasonable one-time manner according to the characteristics of the next-generation network, and the network optimization work should be integrated into the 3G network In planning and engineering construction, try to minimize the impact of network evolution on network service quality.

The fundamental goal of optimization work is to improve or maintain the overall performance of the network and provide users with quality services. Facing the diversified development of network services, network optimization ideas, technical means, and support systems must be comprehensively improved. Network optimization workers must pay close attention to the development and changes of the network, track new network optimization technologies in a timely manner, and learn and master new network optimization technologies. Experience, new skills, constantly updating and expanding knowledge of new businesses and products, following up on new optimization means and methods, and accumulating optimization experience, only in this way can we become a new generation of network optimization experts.

2007 marks the 20th anniversary of the official commercialization of large-scale cellular mobile communication systems in mainland my country.

2007 is the 20th anniversary of the official commercialization of large-scale cellular mobile communications systems in mainland my country. Over the past 20 years, my country's mobile communications industry has grown from scratch, grown from small to large, and attracted the attention of the world with its unprecedented development speed. Compared with 20 years ago, the network scale, technical level and service level of my country's mobile communications have all undergone leaps and bounds. The mobile communications industry has also leapt from the bottleneck that restricted economic construction to a basic industry and a leading industry in the national economy, contributing to the national economy. construction and social development. When my country's mobile communications industry is about to enter a new turning point in development, when my country's telecommunications industry is about to face the challenges of joining the WTO, these 20 years of ups and downs, 20 years of hard work, 20 years of brilliant achievements, 20 years of The experiences and lessons learned are especially worth recalling, summarizing, and thinking about.

What will 20 years bring us?

Exponential growth, leap forward, leapfrog development... This is how people evaluate the 20-year development history of China's mobile communications industry.

A set of data confirms this evaluation. According to statistics, it took a full 10 years from the launch of mobile phone services in my country in 1987 to the number of users reaching 10 million in 1997. The growth from 10 million households to 100 million households in 2001 took less than 4 years. Since then, the total number of mobile phone users has reached 200 million in November 2002; 300 million in May 2004; and 400 million in February 2006. The development speed of my country's mobile communications has created a miracle in the history of world communications. Today, China has more than 487 million mobile phone users, making it the country with the largest number of mobile phone users in the world. It is also the country with the largest GSM and CDMA network capacity in the world. Once, mobile phones were considered an unattainable luxury in China; now, mobile phones have flown into the homes of “ordinary people” and become an indispensable necessity in people’s daily lives.

In 20 years, 630 million seconds, an average of one new user was added every 1.2 seconds. The great changes in 20 years have amazed the world! This change is not only a change in the mobile communications industry itself, but also affects all aspects of public life, radiates to all walks of life related to information, and penetrates into every corner of social development.

——Leading the development of the national economy. The information industry is the pillar industry of our country's national economy and a new economic growth point. It is an important symbol of the country's comprehensive national strength. As the fastest growing industry in the information industry, mobile communications has effectively driven the growth of the national economy and promoted the improvement of people's living standards. , creating a lot of job opportunities.

According to statistics, my country's information industry achieved an added value of 1.52 trillion yuan in 2006, accounting for 7.5% of GDP, of which mobile communications revenue reached 306.4 billion yuan, an increase of 18.5% over the previous year, much higher than the year-on-year growth rate of total telecommunications revenue, accounting for 7.5% of GDP. The ratio of total revenue reached 47.3, and this figure increased again to 48.41 in the first quarter of this year. Mobile communications have become a powerful engine for the development of the information communications industry.

The rise and fall of every industry is closely related to the rise and fall of strong companies in the industry. The rapid development of the mobile communications industry has also spawned China Mobile, Huawei, ZTE and other large companies that are quite competitive in the international telecommunications field. The growth of these companies has not only promoted the development of the national economy, but also promoted the improvement of my country's international economic status. promote. Taking China Mobile as an example, the value created by the company accounted for more than 1.1 of the GDP from 2003 to 2005, and the total demand for the national economy during the same period remained above 2.2. Since 2000, China Mobile has paid a total of 167.008 billion yuan in profits and taxes, and created more than 2.3 million direct and indirect jobs.

——Promote the progress of related industries. To evaluate an industry, we must not only look at its contribution to the national economy, but also consider its radiating effect and influence on other industries. Mobile communications is an industry with strong radiation, penetration and multiplication potential.

With the development of mobile communication technology and the continuous innovation of mobile services, mobile information solutions with the advantages of "mobility, personalization, real-time and security" have penetrated into all walks of life, not only It promotes the integrated utilization of various resources including information, improves the efficiency and effectiveness of enterprises in related industries, promotes the construction of new information-based villages, and changes people's traditional thinking concepts and life and work styles, creating a harmonious information society. made a positive contribution to construction. For example, in government departments, mobile informatization has improved the efficiency of government work, allowing civil servants to process official documents while on business trips. More importantly, it has connected the large amount of information resources owned by the government with the people's large demand for information, allowing the government to We are closer to the people, government affairs are more transparent, supervision is more powerful, and measures are more convenient for the people. In the police system, with the "Mobile Police Communication", public security officers can query and manage data on population, vehicles, fugitives and other information through their mobile phones. This greatly improves work efficiency and increases the social security index. In the coal industry, the mobile safety remote monitoring system can implement remote real-time monitoring of key links related to coal mine safety such as the operation of the main fan in the mine, the operation of gas exceeding the limit, and the working status of the tile inspectors, and transmit the relevant data to the monitoring system in real time. center, effectively improving the safety production factor and reducing the accident rate. In the vast rural areas, information services such as "Rural Information Communication" and "Agricultural New Time and Space" have built an information bridge for farmers to get out of poverty and move towards a well-off society... It can be said that the widespread application of mobile communication technology and services in various industries has reduced the It reduces economic operating costs, improves the quality of economic growth, and exerts an indirect stimulating effect on economic development.

——Convenient for urban and rural people’s life. In the past, mobile phones had a name with Chinese characteristics - Big Brother. Why is it called that? Because when mobile phones first came on the market, one cost tens of thousands of yuan, and the call charges were also very expensive. They were not a luxury product that ordinary people could afford or use. Only "big brother" figures could own them, and they were out of reach of ordinary people. After 20 years of rapid development, by the end of 2006, my country's mobile phone penetration rate had reached 35.3. People who use mobile phones to communicate information can be seen everywhere. Farmers in remote mountainous areas also use mobile phones to connect to the outside world. The mobile phone penetration rate in some cities Even close to 100. Today, as house prices, gasoline prices, and pork prices rise, mobile communication fees continue to fall, bringing real benefits to consumers. While mobile communications are becoming popular among the public, the service quality of mobile communications is also improving day by day. Mobile value-added services such as SMS, MMS, Wap, and ring back tones are constantly being introduced, which have brought changes to people's production and lifestyle, and even influenced the birth of new products. cultural phenomenon.

It is worth mentioning that mobile communications also play an important role in disaster prevention, disaster relief and emergency communication support for important activities, building an irreplaceable "lifeline". From the 2002 Chinese tourists in distress at sea in Vietnam to the 2006 Southeast Asian tsunami, from the typhoons that have ravaged my country's coastal areas in recent years to the recent earthquake in Pu'er, Yunnan... At this critical moment when people's lives and property are seriously threatened and rescue and assistance are urgently needed, A smooth mobile communication network buys time for rescue, and timely SMS notifications buy a chance for life.
