Abstract

The present application relates to the technical field of frequency adaptive switching, and discloses a frequency adaptive switching method in a distributed wireless network, comprising: setting a target time period, a switching trigger holding time and an upper limit of false trigger probability, combining the center frequencies of a service frequency band and an adjacent frequency band, obtaining and calculating a cross-frequency band signal quality difference sequence and an intra-band standard deviation; then, according to the terminal position change and the average moving speed in the target time period, selecting a dominant frequency and calculating an effective Doppler frequency, establishing a monotonic relationship between the effective Doppler frequency and the intra-band standard deviation; finally, combining the holding time and the false trigger probability constraint, solving a dynamic hysteresis threshold to realize adaptive frequency switching. The method can flexibly adjust the switching parameters according to the dynamic changes of the user moving speed and the wireless environment, effectively reduce the risk of excessive switching and ping-pong switching, ensure that the false switching probability is within a controllable range, and thus significantly improve the accuracy, stability and resource utilization efficiency of network switching.
