Embodiment Construction

[0028] 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.

[0029] Firstly, the data setting of the specific implementation example of the present invention is introduced. It is assumed that the popularity of files and the value of files in the present invention obey the Zipf distribution. The file popularity Zipf value is set to 0.58; the file value Zipf value is set to 0.95. Time T=8000, number of users is 250, number of cached files is m=60, number of files is F=1000, h=(0.55, 0.45).

[0030] Such as figure 2 Shown is the flow chart of the algorithm, which specifically includes the following steps:

Abstract

The invention discloses an online learning method of multi-objective active caching based on the principle of linear weighting. The method 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. At the same time, the method of content provider's income is considered. 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, that is, maximizing the cumulative traffic in the offloaded backhaul link within a limited time, it also considers the benefits of content providers, which is specifically reflected in the importance of file value . The method takes multiple objectives into account, 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 for a base station in mobile communication to pre-buffer content required by nearby users from a content provider when the wireless network is idle, and simultaneously consider the content provider's profit. The method is specifically an online learning method of multi-objective active caching based on the principle of linear weighting. 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 WeChat, video, 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. [...
