Problems solved by technology

However, studies have shown that the standby state energy consumption of Android mobile terminals accounts for more than half of the total energy consumption. This is because the openness of the Android system causes third-party applications to abuse Wakelock resources in the background and continuously transmit data through the network interface.

Abstract

The invention discloses a context awareness-based Android mobile terminal power management method. context awareness information of a mobile terminal is used for decision making to predict whether to need a network interface currently, dynamic management is intelligently carried out, and system power consumption in a standby mode is reduced. Related context information is acquired via the system interface of the mobile terminal, pre-treatment is carried out on complicated context information, and a method of acquiring positioning data in an optimization mode is included. The decision making algorithm is an improved k-nearest neighbor algorithm, calculation of a sample distance adopts a weighted Euclidean distance formula, and information gains of an attribute are used for selecting a context information attribute and determining the weight of the attribute. A sample cutting method based on the maximum attribute range is brought forward at the same time, thereby reducing the calculation sample amount in the case of decision making. While the network interface is intelligently managed, power consumption of the Android mobile terminal system in the standby mode can be saved.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal power management, and in particular relates to a situation-aware-based power management method for intelligently managing network interfaces of Android mobile terminals. Background technique [0002] With the rapid development of mobile terminal software and hardware and the popularization of the new generation network 3G and 4G, more and more people use mobile smart terminals and enjoy the convenient services and entertainment brought by them. At present, the number of smart phone users in the world is growing rapidly, and the Android system has occupied most of the market share of mobile smart terminal systems. At the same time, the high performance of mobile terminals, complex applications and heavy games also bring higher power consumption, but the development of battery technology is slow, and the capacity is obviously restricted by its own volume. In conclusion, how to reduce power c...
