Problems solved by technology

[0004] With the above technical solution, when there is idle spectrum in a certain network, the idle spectrum is considered to be allocated to other networks; when there is no idle spectrum in all networks, dynamic spectrum allocation cannot be realized
This limits the flexibility and applicability of spectrum sharing

Abstract

The invention discloses a frequency spectrum sharing method and apparatus and relates to the technical field of wireless communication, for improving the frequency spectrum sharing flexibility and applicability. The frequency spectrum sharing method provided by the invention comprises the following steps: obtaining frequency spectrum income of each network; and distributing a specified frequency range of a first network to a second network so that the second network can transmit service by use of the specified frequency range, wherein the frequency spectrum gain of the first network is smaller than the frequency spectrum gain of the second frequency spectrum. The frequency spectrum sharing method and apparatus are applied to a frequency spectrum sharing process.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a spectrum sharing method and device. Background technique [0002] Wireless spectrum is a limited resource with economic and social value. At present, the main spectrum allocation method is to allocate a fixed frequency band for each network. For example, the uplink frequency band of China Unicom 2G network is 909MHZ-915MHZ, while the uplink frequency band of China Unicom 3G network is 1940MHZ-1955MHZ . With this allocation method, when there is a certain number of idle frequency bands in a certain network, other networks cannot use the idle frequency bands and can only use the frequency bands allocated to themselves, resulting in a waste of spectrum resources. [0003] In order to improve spectrum utilization, a spectrum sharing scheme is proposed in the prior art, specifically: according to the spectrum utilization of different networks, if certain cond...
