Satellite webmastering software as previously mentioned is responsible for distributing the communication resource, after communication link is allocated successfully every time, is just labeled as
Channel resource has been distributed, then can directly obtain idle channel resources according to channel resource has been distributed.
Step S108：When the required channel resource be less than or equal to maximum can communication channel resources when, from the idle letter
The required channel resource is distributed in road resource to the communication link.
The maximum of comprehensive analysis current communications link can communication channel resources, idle channel resources, required channel resource it
Between magnitude relationship, when the required channel resource be less than or equal to maximum can communication channel resources when, select suitable distribution plan
The required channel resource is slightly distributed from the idle channel resources to the communication link.
Above-mentioned satellite communication channel resource allocation methods, the required channel resource of communication link can be obtained, maximum can lead to
Believe channel resource and idle channel resources, the maximum of comprehensive analysis current communications link can communication channel resources, idle channel
Magnitude relationship between resource, required channel resource, select suitable allocation strategy to be allocated it, can ensure that channel provides
The validity of source distribution, effectively avoid channel resource allocation success but the problem of communication failure, improve resource allocation efficiency and
System reliability, practicality.
In one embodiment, the maximum for obtaining the communication link can communication channel resources, specifically include following
Step：
Step S202：Obtain the carrier parameter and satellite repeater parameter of the earth station.Wherein, the carrier wave ginseng of earth station
Number includes quality factor, modulation factor, encoding rate and the demodulation threshold of earth station；The satellite repeater parameter is led to including saturation
Metric density, linear input back-off, satellite repeater channel resource, satellite repeater quality factor, EIRP,
Linear convergent rate fallback value.
Step S204：The relation of equal quantity established between system margin and the carrier parameter and satellite repeater parameter.
The relation of equal quantity can be expressed as：
Wherein, BWXpdCan communication channel resources for maximum；For demodulation threshold；α is modulation factor；β is encoding rate；a
For the first coefficient；B is the second coefficient；It is uplink downlink composite carrier signal power to noise-temperature ratio；Wherein, on described
Downlink composite carrier signal power to noise-temperature ratio and the maximum can communication channel resources, earth station carrier parameter and defend
Star transponder relating to parameters.
In one embodiment, the first coefficient a is 228.6, and the second coefficient b is 1.2, that is,
Step S206：When system margin is equal to zero, obtaining the maximum according to the relation of equal quantity can communication channel money
Source.
When system margin is equal to zero, i.e., the signal intensity that earth station receives reaches demodulation threshold, and then it is to be understood that
Maximum can communication channel resources be channel resource when signal intensity that earth receiving station receives is equal to demodulation threshold.Wherein,
When the first coefficient a is 228.6, and the second coefficient b is 1.2,
By obtaining uplink downlink composite carrier signal power to noise-temperature ratioMaximum, which can be obtained, to communicate
Channel resource BWXpd。
In one embodiment, uplink downlink composite carrier signal power can be obtained according to the first preset formula to noise temperature
Degree ratio：
Wherein,It is uplink carrier power to noise-temperature ratio；It is downlink carrier power to noise

Road transmission loss；For the quality factor of earth station.That is, uplink carrier power is to noise-temperature ratioWith under
Downlink carrier power is to noise-temperature ratioCan use can communication channel resources BW containing maximumXpdThis unknown quantity comes
Represent.
In one embodiment, it can also make maximum can communication channel resources BWXpdFor required channel resource BWC, pass through
Magnitude relation formulaIts system margin is directly calculated, when being
When surplus of uniting is more than or equal to zero, the required channel resource is directly distributed from the idle channel resources to the communication chain
Road.
In one embodiment, the communications band of sensitivity if satellite communication frequency range declines for Ku frequency ranges, Ka frequency ranges etc. to rain,
Uplink carrier power is obtained to noise-temperature ratioWith downlink carrier power to noise-temperature ratioProcess
In, it is necessary to consider that rain declines, because rain declines the noise temperature for adding reception antenna can be caused to change, so GRS/TS, GRE/TE
It may change.Wherein, rain declines, refer to electric wave enter rain layer in caused decay, it include rain grain absorb caused by decay and
Decay caused by the scattering of rain grain；It is due to that rain grain has caused by dielectric loss that rain grain, which absorbs caused decay, and the scattering of rain grain is drawn
The decay risen is due to be reflected and reflect again caused by rain grain when electric wave encounters rain grain.
It is to be understood that can communication channel resources BW obtaining maximumXpdWhen, pass through formula Wherein,Acquisition maximum can be contained can communication channel resources BWXpd
To represent, that is, formulaIn only can communication channel containing maximum
Resource BWXpdOne of unknown quantity, other specification be known quantity, pass through the formula, you can calculating maximum can communication channel resources
BWXpd。
In one embodiment, satellite communication channel resource allocation methods, in addition to judge that the required channel resource is
No the step of being less than the idle channel resources.
When the required channel resource is less than the idle channel resources, and it is described needed for channel resource be less than or equal to maximum
Can communication channel resources when, distributed from the idle channel resources it is described needed for channel resource to the earth station.When described
Required channel resource is more than the idle channel resources, idle channel resources deficiency, the information of feedback allocation failure.
In one embodiment, satellite communication channel resource allocation methods, in addition to when the required channel resource is more than
Maximum can communication channel resources when, change resource allocation policy, and by the maximum can communication channel resources distribution resource step
Suddenly.
In one embodiment, satellite communication channel resource allocation methods, in addition to：The communication link distributes the institute
It it is the step of having distributed state by the communications link indicia after needing channel resource.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
