Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0045] This embodiment is aimed at 5G ultra-dense networks, such asfigure 1 As shown, the virtual cell construction methods based on dynamic quadrants are respectively designed as image 3 As shown, and cooperate with the serving base station switching method based on the received signal-to-noise ratio threshold and the received signal strength difference threshold, Figure 4a with Figure 4b shown. In this embodiment, 60 small cell base stations complying with the Poisson point distribution are deployed within a geographical range of 300m*300m to provide services for 100 mobile user equipments with a moving speed of 2-15m / s. The user movement trajectory model is randomly distributed in one of the three types of circle, straight line and broken line, such as Figure 5 shown. This embodiment considers Rayleigh fading during wireless signal ...
