US 2014/0211654 A1 · Spectrum resource reconfiguration method, device, and system

Abstract

A spectrum resource reconfiguration method is disclosed. The method includes: after spectrum resource configuration is triggered, a spectrum resource configuration decision is generated, and spectrum resources are configured to a to-be-configured link according to the configuration decision. Also disclosed are a spectrum resource reconfiguration device and system for implementing the method. In the disclosure, a spectrum resource Database (DB) is set and stores currently available spectrum resources and used spectrum resources. In this way, when insufficient spectrum resources occur on some links or spectrum resources are unavailable, a system may configure corresponding spectrum resources to the links according to currently available spectrum resources, so that it is ensured that the links with insufficient spectrum resources have available resources, thereby ensuring development of as many services as possible. By means of the technical solution of the disclosure, the use of spectrum resources is more reasonable, all spectrum resources may be fully utilized instead of being limited to specific spectrum resources, thereby maximally utilizing the spectrum resources.

A spectrum resource reconfiguration method, comprising:

after a reconfiguration system triggers spectrum resource reconfiguration, generating, by the reconfiguration system, a spectrum resource reconfiguration decision, and configuring spectrum resources to a to-be-configured link according to the spectrum resource reconfiguration decision.

A spectrum resource reconfiguration system, comprising a Data Base (DB), a Central Control Point (CCP) and a Reconfiguration Base Station (RBS), wherein

the DB is configured to store spectrum resource status information of a main system and information of White Space (WS) resources of the main system used by the CCP;
the CCP is connected with the DB, and is configured to:
collect WS resource requests from the RBS, send a WS resource configuration request to the DB;
coordinate and configure acquired WS resources to the RBS;
receive a spectrum resource reconfiguration command from the DB, control the RBS to perform spectrum resource reconfiguration;
feed back a configuration update message to the DB;
and send a sensing and measurement configuration message to the RBS, and feed a sensing and measurement result back to the DB;
and
the RBS is connected with the CCP, and is configured to configure WS resources indicated by the CCP to each radio link, change or adjust a wireless communication parameter according to an indication of the CCP and perform spectrum sensing and measurement.
