Problems solved by technology

[0004] However, since the scheduling scheme with reduced energy consumption will bring about the delay of network service requests and reduce the user's service performance experience, how to effectively balance the two and meet certain service performance experience indicators to most effectively reduce the terminal Transmission energy consumption is an important issue in current energy-saving optimal scheduling
The current research program is limited to energy-saving measures in specific application scenarios, lacks the description of service performance indicators for ordinary network transmission requests, and considers the trade-off control of energy consumption and performance under different requirements

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] First, a model is established to describe the application service performance experience index, so as to effectively quantify the impact of service delay on the service performance experience index.

[0030] The service performance experience index corresponding to the network transmission request of various applications is defined as a function with the following properties: φ u (·): The time range is [0, t d (u)-t a (u)]; φ u (0)=0; if d 1 >d 2 , φ u (d 1 )≥φ u (d 2 ); u (t d (u)-t a (u))=sup d∈[td(u)-ta(u)] {φ u (d)}; among them, u represents a transmission request packet, t a (u) indicates the arrival time of the transmission request packet, t d (u) represents the maximum tolerable sending time of the transmission request packet. For general periodic application transmission requests, the performance loss fun...

Abstract

The invention discloses a mobile intelligent terminal third-generation (3G) communication energy consumption and user performance experience balancing and scheduling scheme, and belongs to the field of 3G mobile communication energy-saving control. A model for describing an application service performance experience index is constructed; when a mobile terminal sends a network data transmission request, flow arrived in advance is shaped, so that under certain performance loss index constraint, flow convergence can be finished as much as possible by the transmission request; and the tendentiousness between the network transmission energy consumption and the performance experience index can be directly and effectively adjusted by adjusting a balancing factor of an algorithm. By the scheme, long-time high-energy-consumption states caused by 3G communication can be greatly reduced; and under the condition that requirements of different performance experience index are met, the transmission energy consumption of a 3G network can be effectively reduced by adjusting the balancing factor.

Description

technical field [0001] The invention belongs to the technical field of energy-saving control of 3G mobile communication, and relates to a scheduling scheme for balancing energy consumption of mobile intelligent terminal 3G communication and user performance experience. Background technique [0002] With the rapid development of the mobile Internet, mobile communication technology is becoming more and more mature, among which the third generation mobile communication technology (3G) has a significant leap in data transmission quality and bandwidth, bringing a large number of mobile applications and services. With the development of mobile intelligent terminal processing technology, people's demand for various network services is growing rapidly. However, under the rich mobile network services, the battery life of mobile smart terminals has always been a performance bottleneck for the improvement of its user experience. On the one hand, the development of energy-consuming mod...
