Embodiment Construction

[0029] 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.

[0030] 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, the number of users is 250, the number of cached files is m=60, and the number of files is F=1000.

[0031] Such as figure 2 Shown is the flow chart of the algorithm, which specifically includes the following steps:

[0032] Step 1. Cache all the...

Abstract

The invention discloses a wireless caching method based on multi-target multi-arm gambling machine online learning, belongs to the field of mobile communication, and mainly relates to a method that abase station caches content required by a nearby user in advance from a content provider in wireless network leisure time and considers income of the content provider at the same time in mobile communication. The method is simple, and the algorithm complexity is the logarithmic function level. Secondly, the core target of the wireless cache is preferentially considered (i.e., the accumulated flowin the unloading backhaul link is maximized within limited time), and the earnings of the content provider are also considered, i.e., the significance of the file value is specifically expressed. According to the method, multiple targets are considered, and the requirements of a wireless communication transceiver can be well met.

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 a wireless caching method based on multi-objective multi-armed bandit learning (Learning-Based Multi-Objective Multi-Armed Bandits, LB-MOMAB). 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 ...
