Wireless network detection method suitable for high-speed mobile environment

Abstract

The invention discloses a wireless network detection method suitable for a high-speed mobile environment, which is a method combined with an active detection technology and a passive detection technology for judging change of link quality according to a detection result and for dynamically adjusting the detection strategy self-adaptively. Operation steps of the method are as follows: initiating detection, integrating a detection result and adjusting a detection strategy. Due to the fact that the active detection technology and the passive detection technology are combined, the defect that a certain technology is used independently is overcome; the detection period is self-adaptively adjusted according to the change of the link quality, so that the characteristic that the network environment is complex and variable in a high-speed mobile environment is achieved; the problem that the real-time performance and accuracy of wireless network detection of the high-speed mobile network cannotbe guaranteed is solved; and a reliable basis for network resource scheduling in the high-speed mobile environment is provided.

Description

technical field [0001] The invention relates to a wireless network detection method suitable for high-speed mobile environments, which is a method that combines active detection technology and passive detection technology, and judges the change of link quality according to the detection results, and adaptively and dynamically adjusts the detection strategy. . Background technique [0002] There are three major operational networks covering the periphery of the railway. Unfortunately, the general user terminal only supports the access of a single wireless network. On the high-speed railway, due to the Doppler effect caused by the high-speed movement of the train, the access base station switches frequently. Body shielding, poor signal quality of surrounding base stations, and many other reasons lead to very poor connection quality of the single network. The multi-link network cooperative transmission system is proposed to solve this problem. In the multi-link network coordi...
