Content cache optimization method based on edge computing

The invention relates to a content cache optimization method based on edge computing, in order to improve service quality of user business under 5G communication by utilizing regularity of user movement and an optimization theory. The content cache optimization method is characterized by redividing one area according to regularity of a moving track of a user, then performing optimized caching of files by using the optimization theory, and comparing a file transmission time with a user requirement time to determine a user caching mode. By utilizing the optimization theory to perform cache distribution and then optimize the cache, the content cache optimization method ensures as many cache contents as possible, tries to meet user requirements, effectively reduces time delay, then reduces business transmission time delay on that basis, improves cache experience of the user, and achieves a good application prospect. 本发明涉及种基于边缘计算的内容缓存优化方法，利用用户移动的规律性和最优化理论，提高5G通信下用户业务的服务质量。首先根据用户移动轨迹的规律性对某区域进行区域再划分，再利用最优化理论进行文件的优化缓
