Implement method and system to allow different communication systems to coexist in license-free frequency band

Abstract

An implement method and system to allow different communication systems to coexist in a license-free frequency band are disclosed. The invention provides an implement method to allow different communication systems to coexist in the license-free frequency band, and the method comprises the steps of monitoring license-free frequency band sub channels; selecting one or more candidate license-free frequency band sub channels that satisfy alternative conditions; determining, based on the data amount of first data information transmitted by the license-free frequency band sub channels, whether the candidate license-free frequency band sub channels are in an idle state or not; if so, occupying the candidate license-free frequency band sub channels for transmitting second data information, and processing according to a preset information processing mode when the candidate license-free frequency band sub channels are in the idle state; if not, determining whether the candidate license-free frequency band sub channels are in a non-full load state; if so, processing according to a preset information processing mode when the candidate license-free frequency band sub channels are in the non-full load state; and if not, giving up the occupation of the candidate license-free frequency band sub channels temporarily. The invention uses the license-free frequency band for transmitting cellular data, thereby doubling the mobile broadband network capacity and improving the spectral efficiency.

Description

technical field [0001] The invention belongs to the technical field of wireless communication networks, and in particular relates to an implementation method and system for enabling different communication systems to coexist in a license-free frequency band. Background technique [0002] With the rapid development of wireless communication services, the mobile Internet is becoming a new economic growth point for the electronic information industry. However, with the ever-increasing mobile data usage, wireless spectrum resources are becoming increasingly tight. The rapid development of data services puts forward higher demands on wireless resources. LTE and LTE-U research apply LTE technology in the license-free frequency band, which can not only improve spectrum utilization, but also bring new commercial applications. [0003] see figure 1 , which shows a schematic diagram of a real-life network where the LTE / LTE-U cellular system and multiple surrounding WiFi systems are...

Problems solved by technology

[0006] In view of the above-mentioned shortcomings of the existing technology, the purpose of the present invention is to provide a method and system for realizing the coexistence of different communication systems in the license-exempt frequency band, which is used to solve the problem that the existing technology is difficult to achieve. In the communication system, the central controller is selected to obtain the system information such as the transmission rate of each communication system, so as to equitably configure the MAC layer parameters for each communication system. Especially for the LTE system with a high level of security and confidentiality, it will fail due to authentication failure. Unable to obtain system information, resulting in the problem that the LTE system cannot work in the license-free frequency band
