With the rapid development of the communication market and the high penetration rate of mobile phones, it is possible to use mobile phone data to study the development of human activities and urban planning. The main work of this study is to build a big data real-time processing analysis platform, and based on this platform proposes a method to understand the urban population distribution by using of mobile data. Experiments show that dynamic population perception based on mobile phone signaling data can reflect the actual urban population distribution, which is of great significance to urban traffic regulation and public resource allocation optimization.
