Problems solved by technology

[0003] Under normal circumstances, this 10Mb / s-100Mb / s downlink rate can meet common small files and high concurrency requirements; however, when it comes to the transmission of large files and high-definition audio and video, this downlink rate will cause delays , long waiting time, etc., especially when multiple users occupy the same downlink at the same time, it will also cause network congestion

Embodiment Construction

[0055] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056]In the prior art, the traditional macro base station is generally used as the main method, supplemented by MIMO, OFDM and other technologies to improve frequency band utilization, so as to increase the data transmission rate. However, in the case of data transmission only through the traditional macro base station architecture, when multiple users occupy the same downlink at the same time, it is easy to cause network congestion, and the bandwidth resource allocation of the macro base station is unreasonable; and due to data transmission The low rate is not conducive to the transmission of large files. In the process of data transmission, the macro base station itself consumes a lot of power. Therefore, it is difficult to imp...

Abstract

The embodiment of the invention provides a data caching method and device, which are applied to a terminal. The terminal comprises a first terminal and a second terminal. The first terminal is connected with the second terminal, at least one of the terminals is connected with a micro base station, the micro base station is connected with a macro base station, and the method comprises the followingsteps that the first terminal determines a target object cached with target data and having idle downlink resources from the second terminal, the micro base station and the macro base station; and the first terminal acquires the target data from the target object. The second terminal, the micro base station and the macro base station form a three-layer cache architecture, so that the target datais acquired and cached, the probability that a user occupies the same downlink resource at the same time is reduced, the data transmission rate is improved, and the time of waiting for downloading bythe user is shortened.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data buffering method and a data buffering device. Background technique [0002] The exchange between communication and data needs to be realized through the network. The current communication solutions are all based on 4G (theforth generation mobile communications, 4th generation mobile communication), and the traditional macro base stations are supplemented by MIMO (Multiple-Input Multiple-Output, multiple-input multiple-output technology), OFDM (Orthogonal Frequency Division Multiplexing, multi-carrier transmission technology) and other technologies have made breakthroughs, even though MIMO, OFDM and other technologies have improved frequency band utilization, saved bandwidth resources, and increased data transmission. rate, the final downlink rate for users remains between 10Mb / s-100Mb / s. [0003] Under normal circumstances, this 10Mb / s-100Mb / s downlink rate ...
