Description
Technical Field
The present application relates to the field of satellite communications technologies, and in particular, to a method, an apparatus, and a storage medium for determining a satellite communications frequency band.
Background
Currently, beam hopping technology and multi-beam communication have been increasingly used in the satellite communication field. The beam hopping technique can change the direction of a beam through a phased array, so that the beam can be controlled to hop between different wave bits, and communication connection is established with a plurality of wave bits in a time division manner. In addition, the satellite supports multi-beam scheduling and communication, and simultaneously supports a plurality of beams to establish communication connection in different wave positions. Thus, in theory, the satellite may establish a communication connection with m×n wave positions (M is the number of wave positions in which each beam can be switched in a hopping manner on average, and N is the number of wave positions that the satellite can transmit), so as to provide a communication service for users of the plurality of wave positions. Beam scheduling techniques for scheduling beam hops are also under continuous research in order to be able to provide communication services to users with higher efficiency.
During the process of providing communication services by the satellite, the wave beams and wave positions in different frequency bands can be used for communication. The high-frequency wave beam has short wave beam wavelength, so that the stability is poor, the attenuation resistance is poor, but the data transmission rate is higher; the low frequency beam has long wavelength, so the stability is strong, the attenuation resistance is strong, but the data transmission rate is low.
In the actual process of communication between the satellite and each wave position, each wave position changes continuously. If communication is always performed with a high-frequency band high-transmission rate beam, degradation of communication quality may be caused when a beam signal is attenuated due to weather or the like.
However, since the satellite cannot adjust the frequency band of the beam corresponding to the wave position according to the actual situation of the wave position, satellite communication cannot be adapted to the actual situation of each wave position, and thus better communication service cannot be improved for users in the time of beam hopping scheduling.

Dividing a preset communication frequency band into a plurality of frequency bands, wherein a plurality of channels exist in each frequency band, and each channel corresponds to the same spreading code; determining carriers corresponding to all channels, wherein the frequencies of the carriers corresponding to all channels are different; and modulating the data to be transmitted onto a carrier corresponding to the target channel.
Publication number CN115276774a, entitled a multi-channel voice communication method. Firstly, an airplane directly communicates with the ground, the calling is repeated if the calling is unsuccessful, if the preset value of the repetition times is exceeded, the communication is established between the VHF1 non-emergency situation and a satellite, if the communication is successful, the session is ended, if the VHF1 channel is occupied to cause communication failure, the communication should be queued, and the satellite can forward a received signal according to the receiving time sequence; if the aircraft fails to establish communication by using the VHF1 for multiple times, that is, exceeds the preset waiting time, communication is established with the satellite through the VHF3 emergency communication frequency band, and when the VHF3 channel is occupied, the VHF3 is still used for establishing communication continuously.
Aiming at the technical problems that in the prior art, the satellite cannot adjust the frequency band of the wave beam corresponding to the wave bit according to the actual situation of the wave bit, so that satellite communication cannot adapt to the actual situation of each wave bit, and better communication service cannot be provided for users during wave beam hopping scheduling, no effective solution is proposed at present.

Specifically, fig. 4 is a schematic diagram of each wave position in the coverage area of the satellite according to an embodiment of the present application. Referring to FIG. 4, for example, satellite 110 includes a plurality of wave positions P within coverage area 130 1 ~P n And satellite 110 may transmit to the covered plurality of wave positions P 1 ~P n Satellite communication services are provided. Wherein one beam of each satellite 110 may scan multiple wave positions P 1 ~P n Is a single wave position.
FIG. 5 shows a satellite in m beams B according to an embodiment of the application 1 ~B m For each wave position P in coverage range 1 ~P n Schematic of the scan. Referring to FIG. 5, at the same time, satellites 110 may respectively transmit in m beams B 1 ~B m While simultaneously for different wave positions P within the coverage area 130 1 ~P n Scanning is performed, where m < n. Thus, satellite 110 passes m beams at each wave position P 1 ~P n Switching between each other and for each wave position P in a time division manner 1 ~P n Satellite communication services are provided.
Notably, satellite 110 is configured to provide a single wave position P 1 ~P n Is performed periodically (i.e., a beam-hopping period). The beam hopping period refers to the length of time that satellite 110 traverses the BHS allocated by the bits within the cluster, and the beam hopping schedule may vary in units of periods. Typically, all the wave bits are serviced at least once in one hop period. Wherein the BHS is used to indicate the minimum duration allocated to one beam.
Furthermore, in the present embodiment, the different beams B of the satellite 110 1 ~B m Can respectively use different frequency bands and respectively correspond to the wave positions P 1 ~P n A communication connection is established. For example, in the present embodiment, beam B of satellite 110 1 ~B m Can respectively select one frequency band and the corresponding wave position P 1 ~P n A communication connection is established.
Ka frequency band: the Ka band has an operating frequency range of about 26.5 GHz to 40 GHz, with a corresponding wavelength range of about 7.2 mm to 11.3 mm.
Ku frequency band: the Ku band operates at a frequency range of about 12 GHz to 18 GHz, with a corresponding wavelength range of about 2.5 cm to 3.75 cm.
C frequency band: the C band has an operating frequency range of about 4 GHz to 8 GHz, with a corresponding wavelength range of about 7.5 cm to 15 cm.
L frequency band: the L band has an operating frequency range of about 1 GHz to 2 GHz, with a corresponding wavelength range of about 15 cm to 30 cm.
Wherein, from L frequency band, C frequency band, ku frequency band to Ka frequency band, the frequency of wave beam gradually increases, and data transmission rate gradually increases.
Thus, first, satellite 110 determines the current hop beam period T x And each wave position P 1 ~P n The corresponding first communication band (S302). Wherein, the current beam jumping period T x Can be the initial beam-jumping period, the current beam-jumping period T x But may also be other than the initial hop period. At the current beam-jumping period T x In the case of an initial beam-hopping period, the first communication band is an initial communication band. Satellite 110 may select an initial communication band based on the data analysis. For example, satellite 110 is directed to each wave position P 1 ~P n May be arranged to communicate in the C-band.
The satellite 110 then determines the current hop period, associated with each of the wave positions P 1 ~P n Corresponding first communication quality parameter, and determining the previous jump beam period, and each wave bit P 1 ~P n A corresponding second communication quality parameter (S304). Tool withFirst, the satellite 110, for each respective wave position P, at each hop period 1 ~P n Measuring a communication quality parameter M= [ M ] corresponding to the communication quality parameter 1 , m 2 , ..., m L ] T . The number of communication quality parameters may be L, for example. The communication quality parameter is used to indicate a parameter that affects the quality of communication between the satellite 110 and devices within its coverage area 130. The communication quality parameters may include, for example: signal-to-noise ratio, reference signal received power, carrier received signal strength, bit error rate, delay, etc. The number of communication quality parameters (i.e., the size of L) may be set according to the actual situation, and the specific parameters included may also be set according to the actual situation.
For example, in the 1 st hop beam period T 1 Measuring and the beam-jump period T 1 Corresponding communication quality parameter M 1,1 ~M 1,n . Wherein M is 1,j Is represented in the beam-jumping period T 1 The j-th wave position P j Is used for the communication quality parameter of the mobile terminal. Wherein M is 1,j =[m 1,j,1 , m 1,j,2 , ..., m 1,j,L ] T 。m 1,j,1 Is represented in the beam-jumping period T 1 The j-th wave position P j The 1 st communication quality parameter, m 1,j,2 Is represented in the beam-jumping period T 1 The j-th wave position P j Is the communication quality parameter of 2 of (a) is the term 1,j,L Is represented in the beam-jumping period T 1 The j-th wave position P j Is the L-th communication quality parameter of (c). Wherein j=1 to n, and k=1 to l.
Thus, for wave position P 1 There is M 1,1 =[m 1,1,1 , m 1,1,2 , ..., m 1,1,L ] T ；
For wave position P 2 There is M 1,2 =[m 1,2,1 , m 1,2,2 , ..., m 1,2,L ] T ；
......；
For wave position P n There is M 1,n =[m 1,n,1 , m 1,n,2 , ..., m 1,n,L ] T 。
And so on, at the ith hop beam period T i The method comprises the following steps:
for wave position P 1 There is M i,1 =[m i,1,1 , m i,1,2 , ..., m i,1,L ] T ；
For wave position P 2 There is M i,2 =[m i,2,1 , m i,2,2 , ..., m i,2,L ] T ；
......；

Finally, the satellite 110 determines a next hop beam period according to the communication band adjustment strategy, and a second communication band corresponding to each wave position (S308). Specifically, after the satellite 110 determines the next hop beam period according to the first communication quality parameter and the second communication quality parameter based on the neural network, and the communication frequency band adjustment policy corresponding to each wave bit, the satellite 110 adjusts each wave bit to the corresponding second communication frequency band according to the communication frequency band adjustment policy.
For example, satellite 110 determines the and wave position P 1 The probability value of the corresponding communication frequency band adopting higher frequency is 50%And wave position P 1 The probability value of the corresponding communication frequency band is 30% and the corresponding wave position P 1 The probability value for the corresponding communication band with the lower frequency is 20%. Thus, according to the communication band adjustment strategy, the satellite 110 needs to be associated with the wave position P for the next hop beam period 1 The corresponding C band is increased to Ku band. Thereby maintaining the position P with the wave 1 Normal communication of the corresponding device.
As described in the background, during the process of providing communication services by the satellite, the communication can be performed with the wave position by using the wave beams in different frequency bands. The high-frequency wave beam has short wave beam wavelength, so that the stability is poor, the attenuation resistance is poor, but the data transmission rate is higher; the low frequency beam has long wavelength, so the stability is strong, the attenuation resistance is strong, but the data transmission rate is low.
In the actual process of communication between the satellite and each wave position, each wave position changes continuously. If communication is always performed with a high-frequency band high-transmission rate beam, degradation of communication quality may be caused when a beam signal is attenuated due to weather or the like.
However, since the satellite cannot adjust the frequency band of the beam corresponding to the wave position according to the actual situation of the wave position, satellite communication cannot be adapted to the actual situation of each wave position, and thus better communication service cannot be improved for users in the time of beam hopping scheduling.
In view of this, since the present application determines the communication band adjustment policy corresponding to each wave bit in the next hop beam period according to the first communication quality parameter corresponding to the current hop beam period and the second communication quality parameter corresponding to the previous hop beam period, unlike the communication band which is arbitrarily designated for each wave bit in the prior art, in the present application, the communication band adjustment policy corresponding to each wave bit determined by the satellite is determined based on the actual situation change, and therefore the communication band adjustment policy corresponding to each wave bit in the next hop beam period determined by the satellite is the adjustment policy most suitable for each wave bit.
Therefore, the technical effect of adjusting the communication frequency bands corresponding to each wave position according to actual conditions and providing better communication service for users is achieved. The method solves the technical problem that in the prior art, the satellite communication cannot adapt to the actual situation of each wave bit because the satellite cannot adjust the frequency band of the wave beam corresponding to the wave bit according to the actual situation of the wave bit, so that better communication service cannot be provided for users during wave beam hopping scheduling.

Specifically, referring to fig. 6, the neural network includes a first convolution layer and a second convolution layer. The first convolution layer is used for receiving the input first communication quality parameter, and the second convolution layer is used for receiving the input second communication quality parameter. The first convolution layer determines a first communication quality vector according to the first communication quality parameter; the second convolution layer determines a second communication quality vector based on the second communication quality parameter. Further, the first convolution layer inputs the first communication quality vector to the cno layer and the second convolution layer also inputs the second communication quality vector to the cno layer. So that the con layer concatenates the first communication quality vector and the second communication quality vector and inputs them to the input layer.
Therefore, the technical effect that the necessary basis can be provided for determining the next wave beam jumping period and the communication frequency band adjustment strategy corresponding to each wave bit is achieved through the operation.
Optionally, the method further comprises: and scheduling each wave bit according to the determined second communication frequency band. Further optionally, the operation of scheduling each wave bit according to the determined second communication frequency band includes: determining data transmission amounts of all wave bit requirements corresponding to different second communication frequency bands in the wave bits; and determining the number of wave bits corresponding to the second communication frequency band according to the second communication frequency band which is different and the data transmission quantity corresponding to the second communication frequency band which is different.
Specifically, satellite 110 first determines beam B 1 ~B m The number of beams using the Ka band, the number of beams using the Ku band, the number of beams using the C band, and the number of beams using the L band.
Then, satellite 110 determines wave position P 1 ~P n In the above, the data transmission amount D1 of all the wave position demands corresponding to the Ka band, the data transmission amount D2 of all the wave position demands corresponding to the Ku band, the data transmission amount D3 of all the wave position demands corresponding to the C band, and the data transmission amount D4 of all the wave position demands corresponding to the L band are set.
Thus, the satellite 110 determines the allocation ratio between the beam of the Ka band, the beam of the Ku band, the beam of the C band, and the beam of the L band according to the following formula:
(equation 1)
(equation 2)
(equation 3)
(equation 4)
Wherein,for the allocation ratio between the beams of the Ka frequency band and the beams of the Ku frequency band, f1 is the Ka frequency bandF2 is the frequency of the beam of Ku band; />F3 is the frequency of the beam of the C frequency band, which is the allocation ratio between the beam of the Ku frequency band and the beam of the C frequency band; />For the allocation ratio between the beam of the C-band and the beam of the L-band, f4 is the frequency of the beam of the L-band. Accordingly, the satellite 110 can determine the number of beams m1 of the Ka band, the number of beams m2 of the Ku band, the number of beams m3 of the C band, and the number of beams m4 of the L band according to the above-described equations 1, 2, 3, and 4.
Finally, after determining the number of beams of each communication band, the satellite 110 may determine the number of wave positions corresponding to the beams of each communication band. And the satellite 110 may also schedule beam hops according to a known scheme, and thus will not be described in detail herein.
Thus, the satellite 110 determines the data transmission amounts of all the wave bit requirements corresponding to different second communication frequency bands in the wave bits, and determines the operation of the wave bit amounts corresponding to the second communication frequency bands according to the different second communication frequency bands and the data transmission amounts corresponding to the different second communication frequency bands, so that the technical effect of improving the data transmission efficiency is achieved.
