Embodiment 1

[0061] The mobile network (that is, the infrastructure network) is a secondary system, and the user equipment (UE) is a secondary system device.

[0062] Please also refer to Figure 5 to Figure 7 , Figure 7 In the communication process shown, when the spectrum manager receives the idle spectrum resource request SHRRequest sent by the mobile network, such as Figure 5 As shown, the message field "Channel Competitiveness" is marked as "LBT", and the "More Data Flag" is logically true. If the resources allocated by the spectrum manager to the infrastructure network can be continuously used in a peer-to-peer manner, it will be based on Configure the "Idle Spectrum Utilization Policy" for "Standard Type" and "Resource Requirements", and set the "Continuous Use of Spectrum Policy" to "Peer-to-Peer Mode".

[0063] And, based on the "location information" that provides the geographical coverage area, the spectrum manager makes a query of the available spectrum to the geographic lo...

Embodiment 2

[0065] Such as Figure 8 As shown, the difference from the embodiment is that if the SHRResponse field "continuous use of spectrum policy" flag is set to "private use", the mobile network can monopolize idle spectrum resources until the data transmission is completed. For example, the spectrum manager temporarily leases spectrum resources of other licensed users to the mobile network to complete data transmission.

Embodiment 3

[0067] Such as Figure 9As shown, the difference with the above-mentioned embodiments 1 and 2 is that: when the SHRRespons field "continuous use of spectrum policy" flag is set to "opportunistic communication", the mobile network can privately use idle spectrum resources. Once it detects that the primary system needs to occupy channel, the cellular system must quickly release the channel for use by the primary system. For example, a mobile network transmits data in TV white space. If the channel starts to transmit TV signals, the mobile network needs to fall back to the licensed frequency band.

Abstract

The present invention provides an idle spectrum resource management method and a device, wherein idle spectrum resources that are not used by a first system are collected. The idle spectrum resources are composed of licensed spectrum resources and licensed-free spectrum resources. The method comprises the steps of receiving an idle spectrum request from a second system in a preset scenario; and selecting appropriate idle spectrum resources in a spectrum pool for the usage of the second system according to the demand parameters of the idle spectrum request. According to the technical scheme of the invention, the interaction process of the attempt to access idle spectrums is simplified, and the application range is wide. Meanwhile, the signaling overhead is reduced and the time delay is saved. The method and the device are especially suitable for processing bursty data streams, and improve the usage efficiency of idle spectrums.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for managing idle frequency spectrum resources. Background technique [0002] Wireless spectrum resources include licensed spectrum for mobile networks such as CDMA2000, WCDMA, HSPA, LTE and IMT, radio and television broadcasting, GPS, radio astronomy, ground stations for satellite communications, and many other uses; also license-exempt spectrum, Examples include wireless area network (WRAN) broadband access for rural areas and industrial, scientific and medical (ISM) shared frequency bands for wireless local area networks (WLAN) and wireless personal area networks (WPAN). With the rapid development of wireless communication services and the increasing usage of mobile data, wireless spectrum resources are becoming more and more tense, making the contradiction between limited spectrum resources and soaring demand increasingly prominent. In the trad...
