Indoor converged network system and communication access method based on visible light communication

Abstract

The invention provides an indoor integration network system based on visible light communication and a communication access method. The indoor integration network system based on visible light communication comprises a visible light source, a visible light indoor base station and a visible light indoor gateway. The visible light indoor base station comprises a wireless communication module set and a universal link processing module, wherein the wireless communication module set comprises various wireless communication modules, and the various wireless communication modules include a visible light communication module, a wireless cellular communication module and the like, so that various heterogeneous wireless access technologies are supported; the universal link processing module is used for processing data forwarded by the wireless communication module set to generate uplink IP data packets with the uniform formats, distributing links to downlink IP data packets sent by an external network of a core network in a cellular network system, and transmitting the downlink IP data packets to a visible light terminal. The visible light indoor gateway is used for sending the uplink IP data packets to the core network, and forwarding the downlink IP data packets sent by the core network to the visible light indoor base station. Therefore, according to the indoor integration network system based on visible light communication and the communication access method, effective integration between visible light communication and an existing wireless communication system is achieved.

Description

technical field [0001] The present application relates to the field of network fusion of wireless network technology, and in particular to an indoor fusion network system and communication access method based on visible light communication. Background technique [0002] At present, with the mature penetration of communication standards such as 3GPP and LTE / LTE Advanced, large-scale network coverage has been basically solved. How to use limited spectrum resources to meet the ever-increasing data services and the urgent demand for mobile communication network capacity is gradually become a new research hotspot. Especially in the indoor environment, people's work and entertainment needs lead to the continuous enrichment of high-speed services such as streaming media, video-on-demand, and online games, and the requirements for wireless access rates are getting higher and higher. Research on the current operating conditions of mobile communication networks found that indoor plac...
