Problems solved by technology

[0005] However, the current cooperative downloading scheme still has various defects
For example, due to the high cost of cellular network traffic, in order to ensure fairness, in some collaborative download solutions, smartphones need to join the collaborative group before the download starts, and each smartphone needs to start streaming media download at the same time, which leads to the lack of Flexibility, which is greatly limited in actual use
Although other cooperative downloading schemes allow smartphones to dynamically join the cooperative group, they easily lead to huge differences in the cellular network traffic consumed by each smartphone, so it is difficult to promote

Embodiment Construction

[0038] According to an embodiment of the present invention, a method for scheduling collaborative downloading tasks oriented to mobile smart terminals is provided for dynamic streaming media collaborative scenarios.

[0039] figure 1 An application scenario of coordinated downloading oriented to mobile smart terminals in this embodiment is shown. This scenario includes common cooperative terminals and scheduling terminals. figure 1 A is the scheduling terminal, which initiates collaborative download at time t1. It is responsible for information collection, decision calculation, and task assignment related operations. At the same time, it is also used as a collaborative terminal during the collaborative download process, which can be regarded as a special collaborative terminal. . B, C, D, and E are used as different time t in the collaborative download process 2 , t 3 , t 4 , t 5 Collaboration terminals that join the collaboration group respectively. During the collabor...

Abstract

The invention provides a collaborative downloading task scheduling method for mobile intelligent terminals. The collaborative downloading task scheduling method includes that: the current downloading task quantity of all the mobile intelligent terminals is determined according to the historical downloading quantity of all the mobile intelligent terminals which perform downloading collaboratively so as to lead the total quantity of the current expected tasks of all the mobile intelligent terminals to tend to be balanced, wherein the total quantity of the current expected tasks of all the mobile intelligent terminals is the sum of the historical downloading quantity and the current task quantity of all the mobile intelligent terminals; (2) all the collaborative downloading mobile intelligent terminals download corresponding resources through a cellular network link according to the current downloading task quantity determined in the step (1) and share the downloaded resources through the local wireless network. The collaborative downloading task scheduling method and system can support the terminals to dynamically join a collaborative group and avoid too large difference of the cellular network flows consumed by all the terminals.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, in particular, the present invention relates to a method and system for scheduling collaborative downloading tasks oriented to mobile intelligent terminals. Background technique [0002] As streaming media is more and more widely used in smart phones, smart phone users have an increasing demand for streaming media applications. However, due to the frequent link fluctuations and high packet loss rate of the current cellular network system, it will be difficult for a single smartphone's cellular network download capability to provide high-quality streaming media resources and ensure smooth streaming media playback. [0003] At the same time, with the continuous development of terminals with diverse interfaces, almost all current mainstream smart phone devices have cellular network interfaces (such as 3G / 4G network interfaces) and local wireless interfaces (such as WiFi interfaces or...
