Low-power consumption RRC (Radio Resource Control) protocol optimal control method based on data stream prediction

Abstract

A low-power consumption RRC (Radio Resource Control) protocol optimal control method based on data stream prediction belongs to the technical field of wireless communication. Inter-block time (IBT) sequences of data blocks in 3G data streams are captured by using an autoregressive moving average (ARMA) model, and the temporal correlation of the IBT sequences is obtained; and then the tail removal processing based on the energy consumption conversion of a mobile terminal and the predictive error correction processing are implemented for the temporal correlation to finally realize an RRC protocol optical mechanism for reducing power consumption. The method can remarkably reduce the energy consumption of the mobile terminal under the precondition of guaranteeing the user experience. The method captures the temporal correlation in the 3G data streams through a time sequence analysis model, and builds a predictive model. Conversion policies of an RRC state machine are dynamically adjusted by using predictive values of future data streams, so that additional energy consumption is reduced, and better balance is achieved between the user experience and the energy efficiency.

Description

technical field [0001] The present invention relates to a method in the technical field of wireless communication, in particular to a low-power radio resource control protocol (RRC) optimization method based on data flow prediction in a 3G wireless communication network environment. Background technique [0002] 3G mobile communication technology has been widely used all over the world due to its characteristics of high bandwidth and low delay. Its appearance enables more Internet applications (such as streaming media playback, video conferencing, etc.) to run smoothly on various mobile terminals, greatly enriching user experience. At the same time, battery technology on mobile terminals has become a bottleneck, and the issue of terminal energy consumption is attracting more and more research work. [0003] In the 3G network, the radio resource control (RRC) protocol is responsible for the establishment and release of the data link between the mobile terminal (UE) and the b...

Problems solved by technology

The disadvantage of this solution is that it is not suitable for applications with high real-time requirements such as streaming media playback and web browsing.

[0008] Link-layer-based solutions: Some works dynamically adjust the tail time according to network load and transmission requirements, but this will lead to an increase in the number of state transitions of the RRC state machine, and generally speaking, transferring from a low-power state to a high-power state will Brings a delay that can be perceived by the user, so this method will significantly reduce the user experience

Existing solutions do not deeply analyze and utilize the characteristics of 3G network data flow, and cannot meet the existing needs in terms of user experience and energy efficiency.
