Abstract: The explosive growth of mobile video services puts forward higher requirements for future wireless communication networks. Caching technology will greatly decrease the radio resource pressure of the wireless network through content reuse. It is one of the key technologies in the 5th-generation mobile communication to improve the virtual reality, augmented reality and ultra high quality video services quality of experience. A survey on caching technology in mobile edge networks was given. Firstly, the architecture of the mobile edge network is analyzed, and the characteristics of the mobile edge caching are summarized. After the classification of the different caching modes, the technologies in mobility and social aware caching situations were concerned. Finally, the technical challenge and development directions of mobile edge caching are presented.

Key words: caching, mobile edge networks, 5th-generation, device to device
