Problems solved by technology

The second is to ignore the user experience
Attempts to reduce tail energy consumption and transmission energy consumption generally lead to packet transmission delays. Existing optimization schemes usually only aim at reducing energy consumption, and seldom consider user requirements for transmission performance.
Third, it is relatively difficult to realize the proposed scheme
Existing low-level system support schemes (such as optimized RRC timers) usually need to modify some configurations controlled by mobile network operators, while high-level transmission scheduling mechanisms usually need to deal with transport layers (such as TCP congestion control and flow control) and application layers (such as some application interfaces) protocol and configuration, which makes it relatively difficult to implement in real systems

Embodiment Construction

[0033] The specific implementation manner of the present invention will be described in detail below with reference to the drawings and embodiments.

[0034] Such as figure 1 As shown, the energy consumption optimization method for cellular network mobile devices with controllable scheduling order in the present invention is mainly to solve the optimal task transmission scheduling time according to the energy consumption optimization model considering user performance requirements. The design idea is to discretize the time into time slots, and to schedule the transmission of flow data units according to the time slots. Specifically, according to the established energy consumption optimization model, the optimal transmission scheduling time slot for each data unit is calculated in advance, and The mobile application traffic data is scheduled and sent based on the time slot, so as to minimize energy consumption under the condition of meeting user performance requirements. The i...

Abstract

The invention discloses a cellular network mobile device energy consumption optimization method with a controllable dispatch sequence. Time discretization is performed, and therefore time slots are formed. Under the condition that the demand for the transmission performance of mobile applications is met, dispatch sending of flow data of the mobile applications is performed according to the optimal dispatch sending time slot which is calculated in advance, and when multiple applications of a mobile device need to send a certain amount of flow data, flow of the mobile applications is divided into multiple task units; based on the given task unit dispatch sequence, the given arrival time slots, the given deadline and the given user performance demand limitation, under the condition that a transmission energy consumption function, a tail power consumption function and a performance expenditure function are known and according to an energy consumption optimization dynamic programming model, the iterative algorithm is used for solving the transmission dispatch time slot of each task unit, and transmission dispatch is performed on flow units according to the transmission dispatch time slots. According to the cellular network mobile device energy consumption optimization method with the controllable dispatch sequence, under the condition that the demand for the performance of the mobile applications of the user is met, comprehensive optimization is performed on transmission energy consumption and tail energy consumption. The cellular network mobile device energy consumption optimization method with the controllable dispatch sequence has the advantage that the transmission dispatch sequence of the task units is controllable, and the cellular network mobile device energy consumption optimization method can be achieved on mobile terminal devices.

Description

technical field [0001] The invention belongs to the technical field of energy consumption optimization of mobile terminal equipment, and relates to a method for optimizing energy consumption of cellular network mobile equipment with controllable scheduling sequence. Background technique [0002] In recent years, with the rapid development of mobile devices and cellular communication technologies, the processing capability of mobile devices has been significantly improved, and the transmission bandwidth of cellular networks has also been continuously increased, resulting in rapid growth of cellular mobile applications. However, since a large number of mobile applications (especially some energy-intensive high-bandwidth applications, such as VoD and VoIP) consume a lot of energy, the problems of energy consumption and battery life of mobile devices have become increasingly prominent. Therefore, in a cellular mobile network, how to reduce the energy consumption of mobile device...
