Detailed Description
With the gradual maturity of satellite communication technology, orbit and spectrum are very important conditions under which a communication satellite can normally operate, and companies at home and abroad are increasingly speculated on huge communication satellite system schemes to preempt orbit and spectrum resources of the communication satellite. The high-orbit satellite and the low-orbit satellite can only work in a crowded environment due to limited orbit resources and spectrum resources, the high-orbit satellite works in a Ka frequency band, the low-orbit satellite also works in the Ka frequency band, and the ITU stipulates that the communication of the high-orbit satellite cannot be interfered by other orbits, so that high-orbit avoidance is needed. When the position is near the equator, the low-orbit satellite can not interfere the communication of the high-orbit satellite at all, and other times can share the frequency band with the high-orbit satellite.
The spectrum-based satellite control method in this embodiment can be used in a communication system in which a low-earth orbit satellite and a high-earth orbit satellite are combined as described in fig. 1. Referring to fig. 1, a gateway station is connected to a high-orbit satellite and a low-orbit satellite, and respectively controls a high-orbit satellite network composed of one or more high-orbit satellites and a low-orbit satellite network composed of one or more low-orbit satellites, and the gateway station can acquire information of the high-orbit satellite in the high-orbit satellite network and information of the low-orbit satellite in the low-orbit satellite network, process and analyze the information, and after processing and analysis, can send corresponding instructions to the high-orbit satellite and the low-orbit satellite to reasonably regulate and control the high-orbit satellite and the low-orbit satellite, so that the whole communication system is optimized, and the resource utilization rate is improved.
The flow of the spectrum-based satellite control method in this embodiment is shown in fig. 2, and includes the following steps:
and acquiring high-orbit satellite operation parameters and low-orbit satellite operation parameters. The gateway station is in a real-time connection state with the high-orbit satellite and the low-orbit satellite, and can receive various parameters in the operation process of the high-orbit satellite and the low-orbit satellite, such as the parameters of the high-orbit satellite and the low-orbit satellite, such as ID, time, satellite position, operation speed and the like.
And determining a perception parameter according to the high-orbit satellite operation parameter and the low-orbit satellite operation parameter. The sensing parameters comprise sensing length and sensing period, wherein the sensing length and the sensing period are spectrum sensing initiated by the gateway station for the high-orbit satellite and the low-orbit satellite, the gateway station obtains the positions of the low-orbit satellite and the high-orbit satellite according to the operating parameters of the low-orbit satellite and the high-orbit satellite, and when the positions of the high-orbit satellite and the low-orbit satellite are close to the equator, the gateway station shortens the sensing period of the high-orbit satellite and the low-orbit satellite and lengthens the sensing length; when the positions of the high-orbit satellite and the low-orbit satellite are far away from the equator, the gateway station adjusts the sensing periods of the high-orbit satellite and the low-orbit satellite to be long and adjusts the sensing lengths to be short. This is because the low-orbit satellite can not interfere the communication of the high-orbit satellite at all near the equator, so the closer to the equator the shorter the sensing period of the gateway station for the high-orbit satellite and the low-orbit satellite is, the better the state of the low-orbit satellite and the high-orbit satellite can be grasped, and the reasonable regulation and control can be performed.
And carrying out spectrum sensing on the high-orbit satellite and the low-orbit satellite according to the sensing parameters to obtain a sensing result at the first moment. The sensing result comprises busy and idle states of channels of a high-orbit satellite and a low-orbit satellite, spectrum sensing is carried out on all channels of the low-orbit satellite at the first moment to obtain received power pr, the power of all channels of the low-orbit satellite at the first moment when the channels are busy is p, p refers to a standard value, and according to the received power pr and the power p of all channels of the low-orbit satellite at the first moment when the channels are busy, the busy probability of the low-orbit satellite at the first moment can be obtained to be R1 pr/p, because a plurality of channels generally exist on a specific low-orbit satellite, each channel state has two results, namely, busy state or idle state, and R1 refers to an overall probability obtained according to the states of all channels of the low-orbit satellite. Since the high-orbit satellite has a large time-delay property, if the spectrum sensing method of the low-orbit satellite is used for the high-orbit satellite, a certain error is generated, so that generally, the spectrum sensing is not performed on the high-orbit satellite at the first moment, but the spectrum sensing is performed on the channel of the high-orbit satellite before the sensing parameter is adjusted, and of course, if an appropriate method is available, the spectrum sensing can be performed on the high-orbit satellite with a low delay.
And acquiring historical information of the high-orbit satellite channel and historical information of the low-orbit satellite channel. The historical information of the high-orbit satellite channel and the historical information of the low-orbit satellite channel comprise channel IDs, time stamps and busy/idle states of the channels of the high-orbit satellite and the low-orbit satellite, wherein the historical information generally refers to historical information in a period of time before the first moment, and the busy/idle states of the channels are determined to be 1 or 0, busy or idle and the like.
And predicting according to the high-orbit satellite channel historical information and the low-orbit satellite channel historical information to obtain the channel state at the second moment. A time series prediction algorithm, such as a prophet model, may be used to model the high orbit satellite channel history information and the low orbit satellite channel history information based on the timestamps and busy and idle states of the low orbit satellite and the high orbit satellite. And predicting the channel state at the second moment by using the mathematical model to obtain the busy probability R2 of the high-orbit satellite channel at the second moment, wherein the channel state is obtained by prediction, and the channel state is a probability value at the moment. The second time is generally a future time of the first time, such as a future 10ms channel state prediction of the first time, and the time interval between the second time and the first time cannot be too long. The channel state of the low-orbit satellite at the second moment can not be predicted, because the high-orbit satellite and the low-orbit satellite share the spectrum, but the low-orbit satellite needs to avoid the high-orbit satellite, and the high-orbit satellite does not need to avoid the low-orbit satellite. In addition to using a time series prediction algorithm to predict the high and low orbit satellite channel history information, other approaches may be used to predict, such as machine learning, AI deduction, etc.
And obtaining the avoidance probability according to the sensing result at the first moment and the channel state at the second moment. According to the above embodiment, the avoidance probability P is 0.5(R1+ R2) obtained from the busy probability R1 of the low-orbit satellite channel at the first time and the busy probability R2 of the high-orbit satellite channel at the second time.
And controlling the low-orbit satellite to avoid the high-orbit satellite according to the avoidance probability. When the avoidance probability P is greater than 0.5, controlling the low-orbit satellite to avoid the high-orbit satellite; and when the avoidance probability P is less than 0.5, the original frequency spectrum is kept to continue communication.
It should be further noted that, in order to simplify the whole process and reduce the workload, in the step of performing spectrum sensing on the high-orbit satellite and the low-orbit satellite according to the sensing parameter to obtain the sensing result at the first moment, only the low-orbit satellite may be sensed, because the data delay for sensing the high-orbit satellite is too large at this time; in the step of predicting the channel state at the second time according to the historical information of the high-orbit satellite channel and the historical information of the low-orbit satellite channel, the channel state at the second time of the high-orbit satellite can be obtained by predicting only the high-orbit satellite. In addition, since the low-orbit satellite cannot interfere with the communication of the high-orbit satellite at all near the equator, and the other times can share the frequency band with the high-orbit satellite, a position range can be set for the spectrum control method of the embodiment, the position range is near the equator and includes the equator, when both the high-orbit satellite and the low-orbit satellite are located in the position range, the low-orbit satellite is controlled to avoid the frequency band of the high-orbit satellite, and when the high-orbit satellite and the low-orbit satellite are located outside the position range, or when one of the high-orbit satellite and the low-orbit satellite is located outside the position range, the low-orbit satellite is not required to be controlled to avoid the frequency band of the high-orbit satellite in general situations.
