Embodiment Construction

[0045] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0046] The uplink small base station content scheduling method based on buffering and redundancy elimination provided by the present invention includes the following steps:

[0047] Step 1: Establish a content-centric multi-user uplink cell network;

[0048] Step 2: Waiting for the time slot to start, when the time slot starts, all users send content data to the small base station;

[0049] Step 3: After the time slot ends, the small base station performs content redundancy detection and elimination; ...

Abstract

The invention provides an uplink micro base station content scheduling method based on cache and redundancy elimination. The method comprises the following steps: step 1: establishing a content-centric multiuser uplink cell network; step 2: waiting for the start of a time slot, and when the time slot starts, sending content data to a micro base station by all users; step 3: when the time slot terminates, carrying out content redundancy detection and elimination by the micro base station; step 4: judging whether scheduling and uploading are required by the micro base station; if the scheduling and uploading are required, executing step 5; if the scheduling and uploading are not required, executing step 2 again; and step 5: running a scheduling algorithm by the micro base station, sending data requiring the scheduling and uploading to a macro base station, judging whether to terminate the process, if so, terminating the process, and otherwise, executing step 2 again. By adopting the uplink micro base station content scheduling method provided by the invention, the transmission efficiency of the micro base station is improved, the load pressure of a wireless backhaul link is relieved, and the effective bandwidth is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a content scheduling method for an uplink small base station based on buffering and redundancy elimination. Background technique [0002] With the popularization of smart devices such as smartphones and tablets, it is becoming more and more popular for people to use mobile devices to upload a large amount of data, such as using mobile applications such as YouTube and Facebook to upload life events (such as user-generated content or popular pictures and videos) ) to the social network, or to upload the backup data to the data center. In addition, the storage limitations of mobile devices and the emergence of cloud-based services have also accelerated this upload trend. A large amount of data upload not only promotes the unprecedented growth of mobile data traffic, but also puts a lot of transmission pressure on wireless networks, especially wireless backhaul links....
