Problems solved by technology

If a large data item is broadcast and the bandwidth is constant, the data item will occupy the channel for a long time, which will reduce the number of users served per unit time and the quality of service.
Similarly, if the size of the data item is fixed and the bandwidth is relatively small, the time that the data item occupies the channel is relatively long

Embodiment Construction

[0099] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0100] 1. The method provided by the present invention increases the splitting process on the basis of the prior art, as follows:

[0101] Each process can be implemented as a corresponding module using software modularization technology. The system structure of the on-demand periodic data broadcast proposed by the embodiment of the present invention is as follows: figure 1 shown. Assuming that the system includes a server (Server) and multiple mobile clients, the mobile client submits its own request through the upload channel (Up Channel), and the server broadcasts the data item queue through the download channel (Down Channel). The system of the server mainly includes four modules of receiving, acquiring, splitting and scheduling. The receiving module maintains a request queue (Req Queue) composed of system requests, the scheduling m...

Abstract

The invention provides a real-time on-demand data broadcast scheduling method in consideration of sizes of data items, adopts a split idea to process the situation that the sizes of the data items are different, and additionally provides a scheduling method for equal-size data item split (ES-LxRxW) and a scheduling method for unequal-size data item split (US-LxRxW), split stragetries of equal-size data items and adjustment strategies of deadlines, and split strategies of unequal-size data items and adjustment strategies of unequal-size data items of two kinds, i.e. PF and PxBF. Both the scheduling method for the equal-size data items and the scheduling method for the unequal-size data items provided by the invention consider bandwidth and period. A split standard size for the split of the equal-size data items is provided aiming at distribution of different deadlines and distribution of different data item sizes and a split standard size for the split of the unequal-size data items is provided aiming at different data item sizes and different scheduling strategies, so that the real-time situation can be well adapted.

Description

technical field [0001] The invention relates to the field of data broadcast scheduling, in particular to a data broadcast scheduling method in a mobile environment, in particular to a periodical data broadcast considering real-time and on-demand. Background technique [0002] The scheduling algorithm of data broadcasting is the most important and core content in data broadcasting. The data broadcast scheduling algorithm refers to the algorithm that studies which data should be selected for broadcast during the broadcast process, and the sequence of broadcast data. Generally speaking, it is divided into three types: static periodic data broadcasting, on-demand data broadcasting and hybrid broadcasting. This section introduces current research hotspots from four parts: static periodic data broadcasting, on-demand data broadcasting, hybrid broadcasting and indexing. [0003] (1) Static data broadcasting. Most of the static broadcast methods have been studied, and the most in...
