Systemic-function framework based on the dynamic application of above-mentioned common wireless spectrum resource proposes that chain rupture of the present invention is held time
Collocation method and each embodiment of device.
The present invention provides the collocation method that a kind of chain rupture is held time.
Reference picture 2, Fig. 2 are the schematic flow sheet for the collocation method first embodiment that chain rupture of the present invention is held time.It is described
Method comprises the following steps：
The heartbeat response message that step S10, received spectrum access system SAS are sent.
In the present embodiment, Domain Proxy send a heartbeat request and receive SAS and return to SAS at regular intervals
The heartbeat response message returned, to keep the long connection between Domain Proxy and SAS.Domain Proxy received spectrums access
The heartbeat response message that system SAS is sent, the heartbeat response carry signal transmitting and exceeded the time limit the moment (world's unified time), believing
Number transmitting was exceeded the time limit before the moment, and CBSD signal transmitting all meets SAS spectrum authorization, and certainly, the heartbeat response also carries
Other specification, such as new mandate are exceeded the time limit time, heart beat cycle etc..
Step S20, wireless signal transmission equipment CBSD time parameter is obtained, and according to the time parameter and the heart
Jump response information acquisition chain rupture to hold time, it is that the CBSD is perceived and proxy server Domain that wherein chain rupture, which is held time,
It can also continue to launch the duration of wireless signal during Proxy communication disruptions.
In the present embodiment, Domain Proxy are after the heartbeat response message that received spectrum access system SAS is sent,
Wireless signal transmission equipment CBSD time parameter is obtained, and is broken according to the time parameter and the heartbeat response information acquisition
Chain is held time, and wherein chain rupture is held time when being that the CBSD is perceived with proxy server Domain Proxy communication disruptions
It can also continue to launch the duration of wireless signal.
In order to which signal transmitting is exceeded the time limit into moment reasonable disposition to CBSD, the present embodiment proposes a new concept：Chain rupture
Hold time, i.e. CBSD perceives the duration with can also continue to launch wireless signal during Domain Proxy communication disruptions.Set
The purpose that chain rupture is held time is：On the premise of the time is exceeded the time limit in the signal transmitting for not violating SAS mandates, work as Domain
When Proxy is with CBSD communication disruptions, CBSD can also continue to launch wireless signal according to the time, and without stop signal immediately
Transmitting, so as to which that reduces CBSD exits service time.
Illustrated with a CBSD equipment under the EMS of Domain Proxy agencies.First, Domain Proxy pass through
EMS obtains CBSD time parameter, and the time parameter was determined by the reaction time of CBSD own hardwares and software, such as
It can include interrupting detecting period, stop signal launch time etc..After CBSD time parameter is got, Domain Proxy
Time parameter further according to the CBSD and the heartbeat response information acquisition chain rupture received before are held time, specifically,
Domain Proxy can pass through the parameters value included in heartbeat response message and the CBSD got time parameter values
Chain rupture is calculated according to preset algorithm to hold time, according to the different parameters value got, different pre- imputations can be set
Method, can flexibly it be set in specific implementation.
Step S30, when setting frequency spectrum parameter, the chain rupture is held time and is allocated to the CBSD.
In the present embodiment, Domain Proxy hold time the chain rupture got when setting frequency spectrum parameter
It is allocated to the CBSD.
Chain rupture is held time and is synchronized to during " setting frequency spectrum parameter " by the present embodiment Domain Proxy
CBSD.Specifically, Domain Proxy can hold time the chain rupture timer being allocated in CBSD, when CBSD feels
When knowing itself with Domain Proxy communication disruptions, CBSD not launch immediately by stop signal, but starts the timer, fixed
When the time be that the chain rupture is held time, if timer expiry link does not recover normal also, CBSD stop signals transmitting；If
Link-recovery is normal before timer expiry, i.e. CBSD detect with EMS link-recoveries, or receive EMS and Domain
Proxy linkup notifications, then kill chain rupture and maintain timer, CBSD will immediately be received and " set from Domain Proxy are new
Put frequency spectrum parameter " message, now CBSD is according still further to message instruction progress processing accordingly.
In the present embodiment, the heartbeat response message that Domain Proxy received spectrums access system SAS is sent；Obtain nothing
Line signal transmitting equipment CBSD time parameter, and maintained according to the time parameter and the heartbeat response information acquisition chain rupture
Time, wherein chain rupture hold time be the CBSD perceive with can also be after during proxy server Domain Proxy communication disruptions
Supervention penetrates the duration of wireless signal；When setting frequency spectrum parameter, the chain rupture is held time and is allocated to the CBSD.This implementation
Example is by proposing a new concept：Chain rupture is held time, will when Domain Proxy receive SAS heartbeat response every time
The signal transmitting that heartbeat response carries, which exceeds the time limit to be converted to chain rupture constantly, holds time, and only when setting frequency spectrum parameter, will just break
Chain, which is held time, is allocated to CBSD, so as to reduce the interacting message number between Domain Proxy and EMS/CBSD, in addition,
In Domain Proxy and CBSD communication disruptions, CBSD can hold time according to the chain rupture of configuration to be continued to launch wireless communication
Number, CBSD's exits service time when communicating unstable so as to reduce.The present embodiment can reduce Domain Proxy with
Interacting message number between EMS/CBSD, CBSD's exits service time when reduction communication is unstable.
Further, reference picture 3, Fig. 3 are T in the collocation method second embodiment that chain rupture of the present invention is held timeremain's
Calculation process schematic diagram.Described the step of being held time according to the emission parameter and the heartbeat response information acquisition chain rupture, can
With including：
Step S21, judges ttransmitExpireTime–t0≧TheartbeatDuration+Tlink+TshutWhether set up；
Step S22, if so, then responding moment t according to the heartbeat0, signal transmitting exceeds the time limit moment ttransmitExpireTime、
Heart beat cycle TheartbeatDuration, interrupt detecting period Tlink, stop signal launch time TshutWhen calculating the chain rupture maintenance
Between Tremain, wherein：
Tremain=(ttransmitExpireTime–t0)–(TheartbeatDuration+Tlink+Tshut)；
Step S23, if it is not, then taking Tremain=0.
The heartbeat response message that the SAS that Domain Proxy are received in the present embodiment is sent includes：Respond moment t0, letter
Number transmitting is exceeded the time limit moment ttransmitExpireTime, heart beat cycle TheartbeatDuration, the CBSD got time parameter includes：
Interrupt detecting period Tlink, stop signal launch time Tshut。
First, Domain Proxy judge ttransmitExpireTime–t0≧TheartbeatDuration+Tlink+TshutWhether set up,
Held time T if so, then calculating the chain ruptureremainFor：
Tremain=(ttransmitExpireTime–t0)–(TheartbeatDuration+Tlink+Tshut) formula (one)；
If it is not, then take Tremain=0.
Further, reference picture 4, Fig. 4 are T in one embodiment of the inventionremainCalculating schematic diagram.
In the present embodiment, if ttransmitExpireTime–t0≧TheartbeatDuration+Tlink+TshutSet up, for example,
Domain Proxy are in t0Moment such as 15:00:00 receives SAS heartbeats response, and the signal transmitting that heartbeat response carries is super
Moment phase ttransmitExpireTimeFor 15:10:00, heart beat cycle TheartbeatDurationFor 300s, while Domain Proxy are obtained
The CBSD arrived interruption detecting period TlinkFor 60s, stop signal launch time TshutFor 60s, then calculated according to formula (one) disconnected
Chain hold time for：
Tremain=(15:10:00-15:00:00)-(300s+60s+60s)=180s；
Accordingly, Domain Proxy send heartbeat request next time according to heart beat cycle, i.e., the next heartbeat request moment
For：t0+TheartbeatDuration=15:00:00+300s=15:05:00.
If ttransmitExpireTime–t0≧TheartbeatDuration+Tlink+TshutIt is invalid, for example, above-mentioned heartbeat response is taken
The signal transmitting of band exceeds the time limit to be changed to 15 constantly:06:00, now ttransmitExpireTime–t0<TheartbeatDuration+Tlink+Tshut,
Take Tremain=0；
Accordingly, Domain Proxy need to send next heartbeat request, such as next heartbeat before heart beat cycle
Asking the moment can be：ttransmitExpireTime–Tlink–Tshut=15:06:00-60s-60s=15:04:00, so that it is guaranteed that
CBSD stop signals before the moment is exceeded the time limit in signal transmitting are launched, not violate SAS mandates.
It should be noted that due to network switch failure or running software failure and other reasons, CBSD and Domain
Communication disruption, including CBSD and EMS chain ruptures, Domain Proxy and EMS chain ruptures etc. may occur for Proxy.T is setremainCan be with
Ensure that CBSD will not violate the exceed the time limit principles of time of signal transmitting of SAS mandates and be：Under worst case, that is, perform next
CBSD and Domain Proxy communication disruptions and do not recover during secondary Heart Beat procedure, then CBSD can be in t0+TheartbeatDuration+Tlink
+Tremain+TshutMoment, i.e. signal launch moment stop signal transmitting of exceeding the time limit, and will not violate SAS mandates.
Further, due to being required for calculating chain rupture to hold time when Domain Proxy receive heartbeat response every time, it is
The T for avoiding the response of heartbeat twice from being calculatedremainFine difference be present, cause Domain Proxy needs to reconfigure
Tremain, after the step S22, can also include：
Step S24, according to the T being calculatedremain, the mapping value that the chain rupture holds time is obtained according to preset rules.
Now step S30 could alternatively be：
Step S31, when setting frequency spectrum parameter, the mapping value that the chain rupture is held time is allocated to the CBSD.
Specifically, can be by T as a kind of embodiment, Domain ProxyremainDiscretization, that is, set to CBSD's
" chain rupture is held time " is f (Tremain), f represents mapping function, mapping value f (Tremain) it cannot be greater than Tremain.Such as can be with
Take f (Tremain)=[Tremain/ M] * M, wherein, [Tremain/ M] represent to round downwards, especially, and as M=60, [Tremain/M]
Mean that and round the number of minutes downwards, such as f (70)=[70/60] * 60=60.Get mapping value that chain rupture holds time it
Afterwards, the mapping value that the chain rupture is held time is allocated to CBSD by Domain Proxy again when setting frequency spectrum parameter.
In the present embodiment, the heartbeat response message that Domain Proxy received spectrums access system SAS is sent, the heart
Jumping response message includes heartbeat response moment t0, signal transmitting exceeds the time limit moment ttransmitExpireTime, heart beat cycle
TheartbeatDuration；Wireless signal transmission equipment CBSD time parameter is obtained, the time parameter includes interrupting detecting period
Tlink, stop signal launch time Tshut；Judge ttransmitExpireTime–t0≧TheartbeatDuration+Tlink+TshutWhether into
It is vertical；If so, moment t is then responded according to the heartbeat0, signal transmitting exceeds the time limit moment ttransmitExpireTime, heart beat cycle
TheartbeatDuration, interrupt detecting period Tlink, stop signal launch time TshutThe chain rupture is calculated to hold time Tremain
For：Tremain=(ttransmitExpireTime–t0)–(TheartbeatDuration+Tlink+Tshut)；If it is not, then take Tremain=0.This implementation
The chain rupture that example is calculated, which is held time, can not only ensure that CBSD will not violate the signal transmitting that SAS is authorized and exceed the time limit the time, and
And the signal transmitting time of exceeding the time limit authorized to SAS has carried out sufficient utilization so that in CBSD communicates with Domain Proxy
When disconnected, it can at utmost extend CBSD signal transmitting duration, CBSD's exits service time when reduction communication is unstable.
Further, reference picture 5, Fig. 5 are that the flow for the collocation method 3rd embodiment that chain rupture of the present invention is held time is shown
It is intended to.Before the step S30, it can also include：
Step S40, obtain the frequency spectrum distribution state of the CBSD.
Step S50, the chain rupture that the frequency spectrum of the CBSD distributes state and gets is held time and once receives the heart with preceding
The frequency spectrum distribution state of the CBSD and the chain rupture got are held time and are compared respectively when jumping response.
Step S60, if the frequency spectrum distribution state of the CBSD or chain rupture are held time and changed, enable setting frequency spectrum

Hold time with the chain rupture got and be compared respectively, the generation if the frequency spectrum distribution state of the CBSD or chain rupture are held time
Change, then enable and frequency spectrum parameter function is set.
In the front and rear response process of heartbeat twice, the possibility situation that CBSD frequency spectrum distribution state changes is：Frequency spectrum
From scratch, frequency spectrum or power change, frequency spectrum from having to nothing, when CBSD frequency spectrum distribution state changes,
Domain Proxy, which should be enabled, sets frequency spectrum parameter function, and the new SAS frequency spectrum parameters authorized are allocated into the CBSD,
The chain rupture got is held time simultaneously and is synchronized to CBSD.Because the heartbeat response message that the response of heartbeat twice receives may
Difference, thus Domain Proxy according to heartbeat response information acquisition to chain rupture hold time may difference, chain rupture maintain
When time changes, Domain Proxy, which should also be as enabling, sets frequency spectrum parameter function, and new chain rupture is held time together
Walk to CBSD so that CBSD violates SAS mandates at no time.
In the present embodiment, the chain rupture is held time when setting frequency spectrum parameter and is allocated to institute by Domain Proxy
