Description
Technical field
The present invention relates to wireless communication technology, particularly relate to a kind of idle frequency spectrum method for managing resource and device.
Background technology
Radio spectrum resources includes licensed spectrum, such as CDMA2000, WCDMA, HSPA, LTE and IMT's
Mobile network, radio and television broadcasting, GPS, radio astronomy, for satellite communication earth station and many other
Purposes；Also include exempting from licensed spectrum, such as radio area network (WRAN) broadband access and the wireless office of rural areas
Frequency band is shared in industry, science and the medical treatment (ISM) that territory net (WLAN) and Wireless Personal Network (WPAN) use.Along with channel radio
Developing rapidly and growing mobile data usage amount of communication service, radio spectrum resources seems nervous all the more so that limited frequency
Contradiction between spectrum resource and the demand that surges.In traditional frequency spectrum method of salary distribution, do not have the licensed-in user can not
Use licensed band；And some local geographic area Nei Yi operator repeats dispose and use identical licensed spectrum of exempting from, due to seriously
Interference causes service quality to decline even network paralysis, and this greatly limit the availability of frequency spectrum, serious waste of resources undoubtedly.
The appearance of spectrum-sharing techniques and development greatly reduce the restriction of frequency spectrum and the bandwidth constraint to wireless technology development, for
Two grades of frequency spectrum markets can be developed on the premise of not affecting self for frequency spectrum holder (license user), increase economic benefit；
More bandwidth can be brought for a user and access chance.Therefore realize multiple radio system to share same spectrum technology and be subject to
The extensive concern of people.Such as, TV white space is not affecting in the case of TV user uses broadcast television bands, other
Secondary Users can utilize this frequency band.Any satellite operated ground is there is not in the ground that local is not used by Landsat band
In those geographic areas at station, face, other Secondary Users can utilize this frequency band.Further, any frequency spectrum white space is not
Exist any operating oneself be allowed can radio device geographic area in, other Secondary Users all can utilize this frequency band.
If additionally, the frequency spectrum of tradition license user is had more than needed, its idle frequency spectrum can being leased to other system and uses.If exempting from license frequency
Band is idle, and load shedding to exempting from licensed band transmission, the most also can be promoted shared frequency band by tradition license user (such as phone user)
Spectrum efficiency.
In order to coordinate the use of frequency spectrum, IEEE802.19 standard working group is developing coexistence manager (coexistence manager),
TVBD network and different TVBD that this standard is independently operated by phase XOR provide standard coexistence method, reach IEEE802
Wireless standard race can the purpose of most effective use TV white space.
But, this standard only considers TV white space idle frequency spectrum resource, is not directed to other network or system, lacks and expands
Malleability.Owing to different standards follows different agreements, different networks has different bandwidth, if so different is wireless
System operates at same position simultaneously, then can be interfering with each other.In the case, how at the different or independent wireless network operated
Coexistence method is provided effectively to use the method for each idle frequency band to have been resolved not yet with the equipment room using different frequency range.
In this standard, researcher has carried out substantial amounts of research work, it is proposed that much coexist solution.Based on geographical position
The frequency spectrum of data base coexists standard, such as document " Unlicensed operation in the TV bands, " no.FCC 10-174, Sep.
In 2010, introduce the unlicensed operation of the TV frequency range about FCC；Or document IEEE P802.11af/Draftl, document IEEE
1900.6；The document of J.W.Mwangoka, P.Marques, J.Rodriguez " Exploiting TV white spaces in Europe:
The COGEU approach, " IEEE Symposium on New Frontiers in Dynamic Spectrum Access
Networks (DySPAN), 2011, pp.608-612, or " ICT FP7project. " ([Online] .Available:
Http:// www.ict-cogeu.eu) the middle COGEU method etc. introduced.
Additionally, such as Villardi, document " the Enabling coexistence of multiple of G.P., Alemseged, Y.D., et.al..
Cognitive networks in TV white space, " it is recorded in IEEE Wireless Communications, vol.18, no.4,
2011, in give centralized/distributed coexistence mechanism of multiple secondary network and method etc. in TVWS, the type scheme is main
Based on the idling-resource in the licensed band such as TV frequency band, the frequency spectrum resource data base of foundation, and resource using mode.Consider
The term resource allocation mode of time frame relatively big (as hour), seldom relates to the short-term resource distribution of second level, even Millisecond
Mode.
For geographic area, local, each network or system in the short time are consulted or are used in conjunction with same frequency spectrum resource, this patent
Report considers the idle frequency spectrum resource using method in the geographic area, local of the such as special scenes such as market or airport.In this field
Under scape, may be except there is such as TV frequency band white space in spectrum manager, outside the licensed spectrum resource such as satellite band, also
Potentially include and exempt from licensed spectrum resource by each operator deployment and the situation of use.In this case, simple consideration TV frequency
May cannot solve because exempting from licensed spectrum with white space or traditional spectrum manager of other licensed spectrum resource or data base
Use and the problem brought.

Resource, can be collected the idle frequency spectrum resource of surrounding geographical region different frequency range, form a frequency in logic by spectrum manager
Spectrum resource pond.Such as, if licensed spectrum own spectrum is had more than needed, then its idle frequency spectrum is put in spectrum pool, make to other system
With, other system described is probably the system not having licensed spectrum, such as WLAN, it is also possible to self licensed spectrum is
The licensing system exhausted.Spectrum manager assists frequency spectrum holder (the most described the first system, or title main system) management
The frequency spectrum resource used by spectrum sharer's (the most described second system, or title subsystem), improves the availability of frequency spectrum；Preferably,
When main system needs to use some frequency spectrum taken by this system, then subsystem needs to discharge this frequency spectrum immediately.
The idle frequency spectrum that spectrum manager is held comprises but is not only restricted to such as cellular mobile system, TV white space, Landsat band
And other frequency spectrum resource etc. that is blank or that do not used by main system；The present invention property improved idle or applicable subsystem is communicated
Exempting from licensed band to be placed in equally in spectrum manager, in default scene, subsystem can use this money to spectrum manager application
Source.For being operated in the system exempting from licensed band, the first system or second system are main system (when using frequency spectrum resource)
Being again subsystem (during release frequency spectrum resource), wherein, described default scene includes: Administrative Area, commerce area (include such as
Market etc.), railway station or airport etc. can cover wireless signal and the public territory of service is provided, and described license (or claiming to authorize),
Refer to whether spectrum sharer enjoys the use authority of some specific frequency spectrum；For the shared frequency spectrum exempting from licensed band, frequently
Spectrum manager can be intercepted by the cycle and be exempted from licensed band and judge that channel is the most unloaded, if applicable subsystem communication；If it is idle or suitable
Conjunction subsystem communicates, then the share spectrum resources exempting from licensed band can put into spectrum manager.Described idle frequency spectrum is all referring to fitting
Frequency spectrum resource for subsystem transmission data, say, that spectrum manager can understand the letter of the subsystem of all connections in advance
Breath, and it is correspondingly placed into applicable idle frequency spectrum resource for follow-up use.
As shown in Figures 2 and 3, based on spectrum manager and assumed condition, different networks effectively uses idle frequency spectrum resource
Mode substantially two kinds: centralized deployment mode and distributed deployment mode.

Including: idle frequency spectrum uses strategy, shared resource mode mark and persistently uses spectrum policy etc.；Its detailed description refers to
Table 2 below:
Table 2
As it is shown on figure 3, in the case of using distributed way to dispose resource, spectrum manager will be by idle frequency spectrum the Resources list
(SHRList) message responds described idle frequency spectrum resource request, after subsystem selects suitable resource from the Resources list,
Idle frequency spectrum resource confirmation (SHRConfirm) is replied to spectrum manager.
Similar with centralized idle frequency spectrum resource allocation response, distributed space ideler frequency spectrum resource list message (SHRList) is by respectively
Resource usage policy and index thereof in the similar above-mentioned table 2 that individual idle frequency spectrum resource respective channels is used are constituted；Such as, as
Shown in Fig. 4, show an example of idle frequency spectrum field structure in described message；Idle frequency spectrum resource confirmation can be wrapped
Containing call number, according to call number, spectrum manager can determine that the resource that subsystem is selected.
Summary content, in brief, idle frequency spectrum resource request message includes resources requirement, and more data identifies, mark
Quasi-type, and essential information and the channel competition ability such as positional information, this channel competition ability represents that subsystem uses idle frequency
Whether the equipment of spectrum has the ability of competitive channel, monitors (LBT), be not listening to fNon-LBT before transmission before sending) etc.
Use the ability exempting from licensed spectrum.Centralized idle frequency spectrum resource allocation response message includes that idle frequency spectrum uses strategy, such as, rise
Beginning frequency, configured bandwidth, resource occupation duration, frequency band allows maximum transmission power etc.；Shared resource mode identifies, this field
Represent that subsystem uses competitive way to share resource, or privately owned exclusive use resource；Persistently use spectrum policy, represent if
The expectation of known subsystem persistently uses frequency spectrum resource, then just can use privately owned use, opportunistic communication, Peer or
Alternate manner shares frequency spectrum.Distributed space ideler frequency spectrum resource list message is by each idle frequency spectrum resource, and respective channels uses plan
Slightly list and index thereof is constituted.
Principles illustrated based on above-described embodiment, gives the idle frequency of centralized and distributed deployment of spectrum manager separately below
The communication embodiments that spectrum resource is shared for communication equipment in subsystem.Wherein, with mobile network's (infrastructure network), WLAN
Network is subsystem, and user equipment (UE) (User Equipment) or website are the Wireless Telecom Equipment accessing subsystem, tool
Body is as follows:
Mode 1: spectrum manager centralized deployment idle frequency spectrum
If can be according to the idle frequency spectrum of candidate, channel conditions or out of Memory centralized deployment idle frequency spectrum so that idle frequency spectrum
Multiple radio systems of resource are avoided or lower interference each other, then spectrum manager spectrum manager can use collection
Middle management resource is distributed.
Embodiment 1:
Mobile network's (i.e. infrastructure network) is subsystem, and subscriber equipment (UE) is subsystem equipment.
Please also refer in the communication process that Fig. 5 to Fig. 7, Fig. 7 show, when spectrum manager receives what mobile network sent
Idle frequency spectrum resource request SHRRequest, as it is shown in figure 5, this message field " channel competition ability " is designated " LBT ",
And " more data mark " is logical truth, if spectrum manager is distributed to basis and implemented the resource sustainable employing equity of network
Mode uses, then it is according to " type " and " resources requirement " configuration " idle frequency spectrum uses strategy ", and will " persistently make
By spectrum policy " it is set to " Peer ".
Further, based on offer geographical coverage area " positional information ", spectrum manager carries out available frequency to geographic position data storehouse
The inquiry of spectrum.The information returned according to device geographical location and geographic position data storehouse is selected applicable idle frequency band and is provided as candidate
Source.Then candidate resource is inserted idle frequency spectrum resource allocation response message SHRResponse, the most as shown in Figure 6；Then will
SHRResponse sends to mobile network.After the resource obtaining " resources requirement ", mobile network is privately owned at shared frequency band
Exclusive transmission cellular data.Finally, if after Current resource transmission cellular data, follow-up " more data mark " use peer
Formula (such as LBT) competitive channel, completes data transmission.
Embodiment 2:
As shown in Figure 8, the difference with embodiment is: identify if SHRResponse field " persistently uses spectrum policy "
Be set to " privately owned use ", then mobile network can monopolize idle frequency spectrum resource always, until data are transmitted.Such as, frequency spectrum pipe
The frequency spectrum resource of other license user is rented temporarily is completed data transmission to mobile network by reason device.
Embodiment 3:
As it is shown in figure 9, be with the difference of above-described embodiment 1,2: when SHRRespons field " persistently uses spectrum policy "
Mark is when being set to " opportunistic communication ", mobile network can privately owned use idle frequency spectrum resource, once monitoring main system needs to take
The channel being currently in use, cellular system must quickly discharge this channel for main system.Such as, mobile network is blank at TV
Space propagation data, if channel starts transmitting television signals, mobile network needs to return to licensed band.
Embodiment 4:
Especially, as shown in Figure 10, it is with the difference of above-described embodiment, the present embodiment is permitted at other by WiFi network
Can frequency spectrum resource transmitting data.First, when spectrum manager receive WiFi network send carry " channel competition ability "
It is designated " LBT ", after " more data mark " is genuine idle frequency spectrum resource request SHRRequest, if spectrum manager
Distribute to the resource of WiFi network and allow to use Peer, then it can " shared resource mode mark " and " persistently use frequently
Spectrum strategy " it is set to " Peer ", then idle frequency spectrum resource allocation response SHRResponse is sent to WiFi network.
Then, after obtaining resource, WiFi website can use LBT mode in shared frequency band transmission data.
Mode 2: spectrum manager distributed deployment idle frequency spectrum
Example flow as shown in figure 11, if spectrum manager uses distributed AC servo system idle frequency spectrum, then work as spectrum manager
After the SHRRequest message received, spectrum manager is by each idle frequency spectrum resource is random or certain criterion is according to Fig. 3 institute
The form shown, increases manipulative indexing number composition idle frequency spectrum resource allocation response, and feeds back to subsystem (such as cellular mobile network
Network or WiFi network), the subsystem using idle frequency spectrum resource select applicable frequency spectrum resource, result will be selected with free time frequency
Spectrum resource confirms that message feedback transmits data to spectrum manager, subsystem according to the occupation mode of selected frequency spectrum resource.
