Embodiment Construction

[0035] The technical solution of the present invention will be described in detail below according to a specific implementation case. However, it should not be understood that the scope of the above-mentioned subject of the present invention is limited to the following examples, and all technologies implemented based on the content of the present invention belong to the scope of the present invention.

[0036] Firstly, the data setting of the specific implementation example of the present invention is introduced. Assume that the value of file popularity and file in the present invention all obeys Zipf distribution, assume that the number of actions in the collection A is 230 and length is L=500 (i.e. cache file number), file popularity Zipf value is set to 0.72; file value The Zipf value is 0.78. Time T=8000, the number of users is 1000, the value of files is 1000, the number of files is F=10000, and the cache accounts for 5% of the total files.

Abstract

The invention discloses a wireless caching method for multi-objective online learning based on the Super Pareto principle, which belongs to the field of mobile communication, and mainly involves the base station in mobile communication caching the content required by nearby users in advance from the content provider when the wireless network is idle. And at the same time, it takes into account the method of content provider's income. This method is the inheritance and development of the standard UCB single-objective method. This improved method can solve the multi-objective optimization problem in the wireless cache: that is, to maximize the file traffic on the backhaul link in advance during the communication idle period, and at the same time Taking into account the maximum income of its uninstalled files. The method is simple, and the complexity of the algorithm is at the logarithmic function level. Secondly, while prioritizing the core goal of wireless caching, the benefits of content providers are also considered, which is specifically reflected in the importance of file value. The method takes multiple objectives into consideration, and can better meet the needs of both the transceiver and the receiver of the wireless communication.

Description

technical field [0001] The invention belongs to the field of mobile communication, and mainly relates to a method in which a base station in mobile communication buffers content required by nearby users in advance from a content provider when the wireless network is idle, and at the same time takes into account the content provider's profit. Background technique [0002] In recent years, with the gradual popularization of mobile devices with multimedia functions (such as smart phones, tablet computers, etc.), new wireless service applications have also emerged in large numbers, such as iQiyi, Youku, Taobao, Weibo, etc. This makes the function of wireless mobile communication permeate from the initial call to entertainment, office, social areas and other fields. At the same time, this has also contributed to the rapid growth of data traffic in wireless networks. [0003] The explosive growth of mobile data traffic is a huge burden on the existing cellular network infrastruct...
