Embodiment Construction

[0029] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0030] The method of the present invention aims at the problem of insufficient base station access capacity in the existing real-time on-demand data broadcast system structure, and draws lessons from the rapidly developing miniature base station idea, and introduces a virtual node layer into the traditional data broadcast system structure to share base station access expenses , thus a three-layer on-demand data broadcasting system structure is proposed to improve the capacity of the base station.

Abstract

The invention discloses a request preprocessing method for real-time on-demand data broadcast system and capacity improvement. The system comprises a server and a plurality of broadcast cellular networks cell; each broadcast cellular network cell contains a base station, a plurality of virtual nodes VN and a plurality of mobile terminals; the mobile terminal accesses the base station via the wireless network by using the virtual nodes, and the base station accesses the server via a wired optical fiber network. The method comprises the following steps: merging user requests by using an optimalrequest merging algorithm to reduce the number, and the method comprises a merging request priority and pruning algorithm to comprehensively evaluate the merging request priority, prune the excessivemerging requests, thereby reducing the processing request number of the server and improving the system broadcasting efficiency.

Description

technical field [0001] The invention belongs to the field of computer science and real-time on-demand data broadcasting, in particular to a request preprocessing method for a real-time on-demand data broadcasting system and capacity enhancement. Background technique [0002] With the maturity of 4G technology and the rapid development of 5G technology, wireless network and mobile computing are constantly integrated into the daily life of the present invention. Massive mobile data services urgently require a scalable wireless propagation method for large-scale data distribution. Wireless data broadcasting is just such a method. Using channel sharing technology, any number of users can access data at the same time, which is very suitable for information transmission in high-load systems (such as: stock information release system, real-time traffic information release system). According to whether real-time user requests are considered in the broadcasting process, data broadca...
