Problems solved by technology

However, in a mobile environment, due to the different mobile speeds of the terminals, the frequency offset changes at different speeds, so the same smoothing or averaging time will bring different accuracy

Embodiment Construction

[0022] In a nutshell, the solution proposed by the present invention is to first estimate the terminal speed through an appropriate method, and then determine what level or range the terminal speed is in by comparing a threshold value. If the terminal speed is at the first speed level, such as a lower speed level, the terminal correspondingly adopts the control strategy (such as parameters and algorithms) configuration under the lower speed environment; if the terminal speed is at the second speed level with higher speed, Then the terminal correspondingly adopts the control policy configuration in a higher-speed environment, so as to realize high-speed and low-speed performance optimization at the same time.

[0023] In the embodiment of the present invention, the terminal speed is estimated in a so-called "real-time" manner, so that the terminal can sense the change of its own moving speed in time, so that the control strategy can be adaptively changed. "Control strategy" can...

Abstract

The invention relates to a control strategy configuration method and device based on the movement speed of a terminal. The method comprises the following steps: firstly evaluating the movement speed of a mobile terminal, and then determining the speed grade to which the movement speed of the mobile terminal belongs according to a plurality of preset speed grades, wherein the grade of each speed corresponds to at least one group of control strategies related to data receiving and processing of the mobile terminal, and each group of control strategies comprises one or more control strategies; and configuring one group of control strategies for the mobile terminal according to the speed grade of the mobile terminal. The method based on the movement speed of the terminal can be used for respectively finding out an optimal control strategy aiming at different speed environments of the terminal, and ensuring the terminal to achieve the data rate and high conversation performance of the standard requirement at low-speed or high-speed environment.

Description

technical field [0001] The present invention relates to data reception and processing of a mobile terminal, in particular to a method and device for data reception and processing by adopting different control strategies based on the moving speed of the terminal. Background technique [0002] In order to further improve the performance of the existing 3G network, but also to compete with some emerging mobile communication technologies such as WiMAX. At the end of 2004, 3GPP proposed the long-term evolution of 3G, that is, 3G LTE (LongTerm Evolution). 3GPP LTE's technical requirement for terminal mobility is to support both low-speed and high-speed mobility of terminals (such as high-speed rail, maglev, etc.), specifically optimized for low-speed mobility of 0-15km / h, and high performance for 15-120km / h high-speed mobility. 120-350km / h (in some frequency bands should even support 500km / h) can maintain the mobility of the cellular network. [0003] In the mobile environment, ...
