Network access type decision method and device, switching control device, and storage medium

Abstract

The invention discloses a network access type decision method. The method comprises the following steps: acquiring a data transmission rate when a visible light communication channel is unshielded under the current state of a user side; according to a known channel blocking parameter of the previous state and the data transmission rate when the visible light communication channel at the current state is unshielded, determining the access type with the maximum equivalent data rate as the access type of the user terminal at the current state according to a pre-trained nonlinear support vector machine model. The invention further provides a network access type decision device, a network switching control device and a computer readable storage medium. In a hybrid indoor wireless communicationnetwork environment composed of visible light communication and the traditional radio frequency communication, the user can comparatively accurately select the access type with the equivalent data rate at the current state under the condition that the actual channel block parameter is unknown, thereby effectively responding to the adverse influence caused by frequent switching and shielding blocking, and the demands on the transmission rate and the communication quality by the user are satisfied.

Description

technical field [0001] The present invention relates to the technical field of indoor wireless communication, in particular to a network access type decision method, device, switching control device and computer-readable storage medium in a mixed indoor wireless communication network environment composed of visible light communication and traditional radio frequency communication. Background technique [0002] Visible light communication (Visible Light Communication, VLC) technology is considered to be one of the important technologies for future indoor wireless communication systems, and has attracted extensive attention from academia and industry. Due to the continuous increase in the number of mobile terminals and service demands, indoor wireless network data traffic is increasing rapidly, and the drawbacks of the limited spectrum available for radio frequency (Radio Frequency, RF) communication are gradually emerging. In recent years, VLC technology has developed rapidly...

Problems solved by technology

In indoor scenarios, it is difficult to determine the frequency and duration of channel blockage caused by the movement of obstacles. Handover overhead and occlusion effects are issues that need to be considered, which greatly increases the difficulty for users to choose a suitable access type.
