Embodiment Construction

[0024] figure 1 It is a flow chart of a dynamic spectrum sharing method provided by an embodiment of the present invention without adding a spectrum sharing processing network element. In this embodiment, the base station may be an eNB in ​​a long term evolution network (Long Term Evaluation, LTE) network, may also be a base station (Base Transceiver Station, BTS) in a 2G network, may also be an NB in ​​a 3G network, or may be a higher-level Access network elements in the 4G network. Such as figure 1 As shown, this embodiment includes:

[0025] Step 11: The base station determines the first spectrum utilization information of the coverage cell, and the first spectrum utilization information includes one or any combination of the following information: the access failure rate of the coverage cell, the call strength of the coverage cell, and the expected Bandwidth, idle bandwidth of the covered cell, bandwidth configuration information of the covered cell, and edge user equip...

Abstract

The invention provides a method and device for sharing dynamic spectrums. The method includes the steps that utilization information of a first spectrum of a coverage cell is determined by a base station, and the utilization information of the first spectrum comprises one or more of the following information: the access failure rate of the coverage cell, the calling intensity of the coverage cell, the expected bandwidth of the coverage cell, the idle bandwidth of the coverage cell, the bandwidth configuration information of the coverage cell and the edge user device information of the coverage cell. When the dynamic spectrums are shared in a homogeneous system with same network types, the base station sends the utilization information of the first spectrum to an adjacent base station, or when the dynamic spectrums are shared in a heterogeneous system with different network types, the base station sends the utilization information of the first spectrum to a core network, or the base station sends the utilization information of the first spectrum to a wireless resource management server. According to the method and device for sharing the dynamic spectrums, the purpose of sharing spectrum resources is achieved, and the utilization rate of the spectrum resources is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a dynamic spectrum sharing method and device. Background technique [0002] Wireless spectrum is a resource with economic and social value. In broadband wireless communication systems, spectrum resources are becoming more and more precious and scarce. How to efficiently utilize spectrum resources is a hot research topic at present. When the service load among eNBs in the network is unbalanced, spectrum utilization can be improved through spectrum sharing technology. When the service load among various radio access technologies (Radio Access Technology, RAT) in the network is unbalanced, the spectrum utilization rate may also be improved through the spectrum sharing technology. [0003] In the prior art, the base station mainly indicates the load status in the local network through the following messages "RESOURCE STATUS REQUEST (resource status request)", ...
