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 and 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 t...

Abstract

The present invention designs a method for constructing a 5G ultra-dense network virtual cell, which includes: Step 1: Construct a UDN network, and set parameters related to the transmit power, receiving signal-to-noise ratio threshold, wireless channel bandwidth, and wireless signal attenuation coefficient of all base stations in the network; Steps 2: Randomly generate users with different movement rates and trajectories; Step 3: The macro base station periodically constructs dynamic quadrants based on the user's current location and instantaneous movement direction, and selects synchronization base stations based on the received signal strength of all small cell base stations received by the user. Construct the virtual cell of the user at this moment; Step 4: The macro base station periodically selects the serving base station for each user based on the received signal-to-noise ratio threshold and the received signal strength difference threshold; Step 5: Calculate the transmission rate and collect statistics on the throughput information. The virtual cell construction method of the present invention can solve the problems of frequent user service base station switching and Ping-Pang effect in traditional UDN networks.
