Description
Technical field
The invention belongs to the spectrum information transmission method under the communications field, more particularly to a kind of control and bearing separation structure
And device.
Background technology
Current frequency spectrum Distursement is fixed allocation, i.e., government is the fixed money of the specific transactions distribution of specific user
All using fixed frequency, some of frequencies are not to use always for source, such as TV, broadcast, radar, navigation, nor
Using everywhere, some periods or some geographical position thus be present, part frequency is not used sufficiently.Research
Show there are a large amount of frequency spectrums to be underutilized in the frequency spectrum of fixed allocation at present, which results in the very big wave of frequency spectrum resource
Take.In the not high frequency spectrum of distribution of these availability of frequency spectrums, TV business occupies below 800MHz VHF（English：Very
High frequency, Chinese：Very high frequency(VHF)）And UHF（English：Ultra High Frequency, Chinese：Superfrequency）Low-frequency range
In the best frequency range of hundreds of million propagation characteristics.Compared to 2GHz, the covering advantage of below 800MHz frequency spectrums is fairly obvious, in TV frequencies
Duan Zhong, not every channel are all being used in all when and wheres, are being not used in some times and place, these
Frequency spectrum is referred to as the white frequency spectrums of TV.Utilize CR（English：Cognitive Radio, Chinese：Cognitive radio）Technology realizes honeycomb system
The dynamic spectrum access united to TV frequency ranges, so as to solve the covering problem in low density of population area, Cellular Networks can be substantially reduced
The lower deployment cost of network.Cognitive radio finds these whenever and wherever possible by way of cognitive radio spectrum environment or database
The vacant frequency range occurred, and do not disturbing PU（English：Primary User, Chinese：Primary user）On the premise of dynamic access
These frequency ranges, realize the use for formula of seizing every opportunity so as to improving the availability of frequency spectrum.
In CR systems, when primary user occurs, secondary user must exit currently used frequency range in time, avoid to primary
Family interferes, and subsystem is in order to ensure the continuity of business, it is necessary to carry out frequency spectrum switching.When subsystem uses TV channels,
Need to DB（English：Database, Chinese：Database）Apply for new channel, in order to avoid the equipment telecom operators is straight
Connect exposure in the internet, we introduce SM（English：Spectrum Manager, Chinese：Spectrum manager）；In LTE（English
Text：Long Term Evolution, Chinese：Long Term Evolution）The network architecture in, eNodeB（Evolved Node B, evolution
Type base station）, MME（English：Mobility Management Entity, mobile management entity）It is 3GPP（English：3rd
Generation Partnership Project, Chinese：Third generation partner program）The pass of the LTE access networks of agreement
Key control node, it is responsible for the UE (English of idle pulley：User Equipment, Chinese：User equipment) or relaying positioning,
Call process.
OpenFlow technologies are proposed that OpenFlow realizes point of data forwarding and route test by Stanford University earliest
From, and define an operational set of bottom data path opening.Following researcher's can is in controller
The cofree operation for calling bottom programs, so as to realize the reform and innovation of network, generally by data forwarding and route test
Separation be referred to as control and carrying separation.
As the thought that will be controlled and carrying separates is incorporated into Radio Network System, there is a kind of new wireless network

Link carries）The scheduling of resource, the scheduling to radio spectrum resources etc..
, interface all be present between other network elements in core network elements of the Controller as the framework, wherein
OR is used between controller and wireless access network（English：open radio）1 interface, controller and user terminal it
Between use OR2 interfaces, OR3 interfaces are used between controller and OTT operators or virtual operator；In addition this framework is also fixed
Billing interface between Yi Liao telecom operators and OTT operators：OR4 interfaces.Above-mentioned OR interfaces are the customized interface of producer.
