The communication industry is undergoing tremendous changes in the 5G era, which is a huge opportunity for operators. Digital economy will bring a bright future to telecom industry. The digital economy is booming, and the industrial digitalization formed by the integration of informationization and all walks of life is becoming the main driving force for the growth of the digital economy. Liu Aili, former general manager of China Telecom, believes that in the face of the new situation, operators need to embark on the journey of digital transformation and become the same strategic choice as integrated service providers and "pipeline+platform+content" operators, who have gradually become the mainstream operators in the world. 5G has become the focus of a new round of international competition in the field of communication. Shang Bing, chairman of China Mobile, said that the 5G era will be an important watershed for the telecom operation market to create a new model and build a new pattern. "Better understanding and cultivating the vast market of 5G applications, better adapting to and grasping the direction of operational transformation will achieve more sustainable and higher quality development." Derui Consulting believes that there are three main development opportunities for telecom operators in the 5G era: one is to transform cloud computing operators; Second, the network instant service provider; Third, differentiated terminal providers. How to transform operators in the "post-traffic era" Faced with the weak growth of traditional services, operators should reduce their dependence on traditional services and accelerate the opening of new tracks. Cloud computing, big data and the Internet of Things are important directions. No matter in the past, present or future, in the ups and downs of the telecommunications market, operators can only be invincible in competition and development if they actively meet the needs of the market and users. The bright future of telecom industry is worth looking forward to.
