Method, device and storage medium for processing data by satellite-based distributed network
Technical Field
The present application relates to the field of satellite data transmission technologies, and in particular, to a method, an apparatus, and a storage medium for processing data in a satellite-based distributed network.
Background
With the continuous development of internet technology, networks can be classified according to working modes, and the networks can be specifically classified into: centralized networks and distributed networks. A distributed network is a network of computer systems interconnected by computer systems having independent operating functions. The core idea of the distributed network is to enable a plurality of servers to work cooperatively to finish tasks which cannot be processed by a single server, especially tasks with high concurrency or large data volume.
But processing data using a wireless-based distributed network has a problem of high latency. Therefore, based on the above-mentioned problems, a data processing method based on satellite networking is also proposed. The satellite networking refers to a network mode formed by satellite groups, wherein the network is formed by a plurality of types of satellite systems on different orbits. And wherein the satellite is able to join the network with the "identity" of the server, thereby completing the processing of the data.
However, when the amount of data to be processed is large, the power consumption of each satellite in the satellite network for processing the data is necessarily increased. Further, satellite networking is very limited in energy resources due to the limitations of the environment in which it is located, and is not suitable for processing large amounts of data.
The publication number is CN101932065A, named as a distributed satellite network resource discovery method. The method comprises the following steps: when the distributed satellite network is initialized, each node sends a resource information advertisement packet to other nodes, and each node respectively establishes a resource information routing table; after the distributed satellite network is initialized, each node queries the resources by the following method: firstly, inquiring local resource information, and ending the inquiry if the local resource information meeting the condition can be provided; otherwise, the query information is routed to other nodes in the distributed network for query.
The publication number is CN103634842A, and the name is a distributed satellite network inter-group routing method. Comprising the following steps: when data of a source satellite group in the distributed satellite network needs to be transmitted, a routing request is transmitted to a main satellite of each satellite group in the distributed network; when a routing request reaches a satellite group main satellite, collecting satellite information and an pheromone value in an AODV routing protocol; calculating the probability that the routing request is to be sent to each satellite according to a next hop selection algorithm, and selecting the next hop satellite for sending the routing request from each satellite according to the calculated probability of each satellite; updating local pheromone according to the link delay and the available bandwidth of the link after passing through one satellite, and selecting a next hop satellite for sending a routing request according to the local pheromone; when the destination satellite receives the route request, a route reply is generated, thereby establishing a reverse route between the source satellite and the destination satellite.
Aiming at the problem that the prior art has high delay when a wireless network-based distributed network is utilized to process data; when satellite networking is utilized to process data, the technical problem that the satellite networking is not suitable for processing a large amount of data due to limited energy resources is solved, and no effective solution is proposed at present.

In the above-described operating environment, according to a first aspect of the present embodiment, there is provided a method of processing data by a satellite-based distributed network, the method being implemented by the processor shown in fig. 2A and 2B. Fig. 3 shows a schematic flow chart of the method, and referring to fig. 3, the method includes:
S302: the first satellite responds to a data processing request sent by the source mobile terminal and receives data corresponding to the source mobile terminal;
s304: the first satellite establishes communication connection with a ground station in a first communication coverage area based on a data processing request, and determines a first target ground station according to a preset priority standard;
s306: the first satellite transmits data corresponding to the source mobile terminal to a first target ground station, and the first target ground station processes the data corresponding to the source mobile terminal; and
s308: the first target ground station establishes communication connection with the target mobile terminal and transmits data corresponding to the source mobile terminal to the target mobile terminal.
Specifically, referring to fig. 1A and 1B, first, in a case where the source mobile terminal 30 is within the first communication coverage of the first satellite 10, the source mobile terminal 30 establishes a communication connection with the first satellite 10, and transmits data and a data processing request to the first satellite 10 by remote control or data transmission.
Then, the first satellite 10 receives data corresponding to the source mobile terminal 30 in response to the data processing request transmitted by the source mobile terminal 30 (S302).
Further, the first satellite 10 establishes a communication connection with the ground stations 201 to 20n in the first communication coverage area based on the data processing request, and determines a first target ground station according to a preset priority standard (S304). The priority criteria may include, for example, an arithmetic processing capability of each ground station 201 to 20n, a data transmission rate of each ground station 201 to 20n, and a distance between each ground station 201 to 20n and the target mobile terminal 40. And, because all the ground stations 201 to 20n meeting the priority standard can be used as the first target ground station, the first target ground station can be one or a plurality of first target ground stations.
Specifically, fig. 4A is a schematic diagram of determining a first target ground station by the first satellite 10 based on the priority criteria when the source mobile terminal 30 and the target mobile terminal 40 are the same mobile terminal according to the embodiment of the present application. Referring to fig. 4A, the first satellite 10 determines that the first target ground station is a ground station 202 based on priority criteria and establishes a communication connection with the ground station 202.
Fig. 4B is a schematic diagram of the first satellite 10 determining a plurality of first target ground stations according to the priority criteria when the source mobile terminal 30 and the target mobile terminal 40 are the same mobile terminal according to an embodiment of the present application. Referring to fig. 4B, the first satellite 10 determines that the first target ground stations are the ground station 201, the ground station 202, and the ground station 203 based on the priority criteria, and establishes communication connection with the ground station 201, the ground station 202, and the ground station 203. The foregoing will be described in detail later, and thus will not be described in detail here.
Fig. 5A is a schematic diagram of the first satellite 10 determining a first target ground station according to the priority criteria when the source mobile terminal 30 and the target mobile terminal 40 are not the same mobile terminal according to an embodiment of the present application. Fig. 5B is a schematic diagram of the first satellite 10 determining a plurality of first target ground stations according to the priority criteria when the source mobile terminal 30 and the target mobile terminal 40 are not the same mobile terminal according to an embodiment of the present application. Referring to fig. 5A, unlike fig. 4A described above, the ground station 202 (i.e., the first target ground station) establishes a communication connection with the target mobile terminal 40, where the target mobile terminal 40 is not the same mobile terminal as the source mobile terminal 30. Referring to fig. 5B, unlike fig. 4B described above, the ground station 201, the ground station 202, and the ground station 203 (i.e., the first target ground station) establish a communication connection with the target mobile terminal 40, where the target mobile terminal 40 and the source mobile terminal 30 are not the same mobile terminal.
Further, the first satellite 10 transmits data corresponding to the source mobile terminal 30 to the first target ground station, and the first target ground station processes the data corresponding to the source mobile terminal 30 (S306). The first target ground station may be, for example, a server for processing data.
Specifically, referring to fig. 4A or 5A, after the first satellite 10 establishes a communication connection with the ground station 202 (i.e., the first target ground station), data corresponding to the source mobile terminal 30 is transmitted to the ground station 202, and the ground station 202 processes the data corresponding to the source mobile terminal 30.
Referring to fig. 4B or 5B, after the first satellite 10 establishes a communication connection with the ground station 201, the ground station 202, and the ground station 203 (i.e., the first target ground station), data corresponding to the source mobile terminal 30 is transmitted to the ground station 201, the ground station 202, and the ground station 203, and the data corresponding to the source mobile terminal 30 is processed by the ground station 201, the ground station 202, and the ground station 203.
Further, when the first target ground station is a plurality of ground stations, the data can be divided proportionally, and each part of data with a predetermined proportion is transmitted to each ground station, and each part of data with a predetermined proportion is processed simultaneously by each ground station, so that the rate of processing the data can be increased. The foregoing will be described in detail later, and thus will not be described in detail here.
Finally, the first target ground station establishes a communication connection with the target mobile terminal 40 and transmits data corresponding to the source mobile terminal 30 to the target mobile terminal 40 (S308). In particular, referring to fig. 4A or 5A, the ground station 202 (i.e., the first target ground station) establishes a communication connection with the target mobile terminal 40, thereby transmitting the processed data to the target mobile terminal 40. Referring to fig. 4B or 5B, the ground station 201, the ground station 202, and the ground station 203 (i.e., the first target ground station) establish a communication connection with the target mobile terminal 40, thereby transmitting the processed data to the target mobile terminal 40.
As described in the background, there is a problem in that the delay in processing data using a wireless-network-based distributed network is high. Therefore, based on the above-mentioned problems, a data processing method based on satellite networking is also proposed. The satellite networking refers to a network mode formed by satellite groups, wherein the network is formed by a plurality of types of satellite systems on different orbits. And wherein the satellite is able to join the network with the "identity" of the server, thereby completing the processing of the data.
However, when the amount of data to be processed is large, the power consumption of each satellite in the satellite network for processing the data is necessarily increased. Further, satellite networking is very limited in energy resources due to the limitations of the environment in which it is located, and is not suitable for processing large amounts of data.
Accordingly, in the embodiment of the present application, the first satellite 10 is regarded as the scheduling device, and the ground stations 201 to 20n communicatively connected to the first satellite 10 are regarded as the server, so that the data received by the first satellite 10 and transmitted by the source mobile terminal 30 can be transmitted to the first target ground station according to the distribution ratio, and finally processed by the first target ground station. Because the embodiment of the application does not directly treat the data sent by the source mobile terminal 30 by using the first satellite 10 as a server, but transmits a large amount of data to the ground stations 201-20 n which are in communication connection with the first satellite for treatment, the problem of limited energy resources when the data are treated by utilizing satellite networking is avoided. Further, since the embodiment of the present application uses the first satellite 10 to transmit data and uses the first target ground station to process data, compared with the problem of high delay when the existing wireless network-based distributed network processes data, the embodiment of the present application can accelerate the data processing rate. Therefore, the technical effects of processing a large amount of data and ensuring the efficiency of processing the data can be achieved. Further, the problem that the delay is high when the data is processed by using the distributed network based on the wireless network in the prior art is solved; when satellite networking is utilized to process data, the method is not suitable for processing a large amount of data due to limited energy resources.
Optionally, based on the data transmission request, establishing a communication connection with a ground station in the first communication coverage area, and determining the operation of the target ground station according to the preset priority standard, including: the first satellite determines one or more ground stations as first target ground stations according to a preset priority standard.
Specifically, since the ground stations satisfying the priority criteria can all be the first target ground station, the number of the first target ground stations may be one or plural.
For example, referring to fig. 4A or 5A, the first satellite 10 determines that the ground station 202 is a first target ground station according to a preset priority criterion, so that the first satellite 10 transmits data corresponding to the source mobile terminal 30 to the ground station 202, and the ground station 202 processes the data and transmits the processed data to the target mobile terminal 40.
Referring to fig. 4B or 5B, the first satellite 10 determines that the ground station 201, the ground station 202, and the ground station 203 are first target ground stations according to a preset priority standard, so that the first satellite 10 transmits data corresponding to the source mobile terminal 30 to the ground station 201, the ground station 202, and the ground station 203, processes the data by the ground station 201, the ground station 202, and the ground station 203, and transmits the processed data to the target mobile terminal 40.
Thus, by using a plurality of first target ground stations to simultaneously process data corresponding to the source mobile terminal 30, a technical effect of accelerating the efficiency of processing data can be achieved.
Optionally, determining the operation of the one or more ground stations as the first target ground station according to the preset priority criteria includes: the first satellite determines priority probabilities corresponding to all ground stations according to priority standards and based on a neural network; the first satellite judges whether the priority probability of each ground station is larger than a preset priority probability threshold; and the first satellite determining a ground station having a priority probability greater than a priority probability threshold as a first target ground station.
Specifically, first, the first satellite 10 determines the priority criteria set in advance and the parameters of the priority criteria corresponding to the respective ground stations. The priority criteria may be, for example, the processing capability of each ground station 201 to 20nS 1 ~S n Data transmission rates of the respective ground stations 201-20 nV 1 ~V n And the distance between each ground station 201-20 n and the target mobile terminal 40L 1 ~L n 。
Then, the first satellite 10 inputs parameters of the priority criteria corresponding to the ground stations 201 to 20n into the neural network model, and obtains the priority probabilities corresponding to the ground stations 201 to 20 n. FIG. 6 is a schematic diagram of a method for determining a location in accordance with an embodiment of the application A neural network schematic of the priority probabilities corresponding to the head station 201, the ground station 202, the ground station 203, and the ground station 204. Referring to fig. 6, the neural network is provided with an input layer, a hidden layer, an output layer, and a softmax classification layer. First, the first satellite 10 determines parameters of priority criteria corresponding to the ground stations 201, 202, 203, 204. For example, the arithmetic processing capability of the ground station 201S 1 Data transfer rateV 1 And distance to the target mobile terminal 40L 1 The method comprises the steps of carrying out a first treatment on the surface of the Operational processing capabilities of ground station 202S 2 Data transfer rateV 2 And distance to the target mobile terminal 40L 2 The method comprises the steps of carrying out a first treatment on the surface of the Computing processing capability of ground station 203S 3 Data transfer rateV 3 And distance to the target mobile terminal 40L 3 Arithmetic processing capability of ground station 202S 4 Data transfer rateV 4 And distance to the target mobile terminal 40L 4 . Wherein the parameters of the priority criteria corresponding to ground station 201, the parameters of the priority criteria corresponding to ground station 202, the parameters of the priority criteria corresponding to ground station 203, and the parameters of the priority criteria corresponding to ground station 204 may form a vector matrixA 1 (i.e., vector matrix in FIG. 6) A 1 ）。
The first satellite 10 then matrices the vectorsA 1 Input to the neural network model to output a priority probability corresponding to the ground station 201 asP 1 The priority probability corresponding to the ground station 202 isP 2 The priority probability corresponding to the ground station 203 isP 3 And a priority probability corresponding to ground station 204 ofP 4 . For example, the priority probability corresponding to ground station 201 is 10%, the priority probability corresponding to ground station 202 is 30%, the priority probability corresponding to ground station 203 is 25%, and the priority probability corresponding to ground station 204 is 35%.
Further, the first satellite 10 determines whether the priority probability of each ground station is greater than a preset priority probability thresholdP k . The preset priority probability threshold may be 25%, for example.
Determining the ground station as a first target ground station in the case that the priority probability corresponding to the ground station is greater than a preset priority probability threshold; and eliminating the ground station under the condition that the priority probability threshold value corresponding to the ground station is smaller than or equal to the preset priority probability threshold value. For example, the first satellite 10 may be compared to determine that, among the ground station 201, the ground station 202, the ground station 203, and the ground station 204, the ground station 202 and the ground station 204 satisfy the condition as the first target ground station, so that the ground station 202 and the ground station 204 may be the first target ground station.
Therefore, the operation that the priority probability corresponding to each ground station is determined according to the priority standard and based on the neural network and the priority probability is larger than the priority probability threshold value achieves the technical effects that the optimal ground station can be selected and the data processing efficiency is improved.
Optionally, the operation of determining the plurality of ground stations as the first target ground station and processing data corresponding to the source mobile terminal through the first target ground station includes: the first satellite determines a data processing proportion corresponding to each first target ground station, wherein the data processing proportion is used for indicating the proportion of the priority probability of each target ground station to the sum of the priority probabilities of all target ground stations; splitting data corresponding to the source mobile terminal by the first satellite according to the data processing proportion; and the first satellite transmits the split data to the corresponding first target ground stations, and the first target ground stations process the data corresponding to the source mobile terminal.
Specifically, if the first satellite 10 determines a first target ground station according to the priority criteria, the first satellite 10 transmits data corresponding to the source mobile terminal 30 to the first target ground station and the first target ground station processes the data. Thus, when there is only one first target ground station, the processing of data corresponding to the source mobile terminal 30 is completed on all of the one first target ground station.
Further, if the first satellite 10 determines a plurality of first target ground stations according to the priority criteria, the first satellite 10 needs to determine the data processing proportion corresponding to each first target ground station further according to the data processing performance corresponding to each first target ground station. Wherein the data processing proportion is used for indicating the proportion of the priority probability of each first target ground station to the sum of the priority probabilities of all first target ground stations.
Referring to fig. 4B or 5B, after determining a plurality of first target ground stations, the first satellite 10 further determines the data processing proportions corresponding to the respective first target ground stations. For example, the first satellite 10 determines that the ground station 202 and the ground station 204 are the first target ground station, and based on the output result of the neural network, the priority probability corresponding to the ground station 202 is 30% and the priority probability corresponding to the ground station 204 is 35%. Fig. 7 is a schematic diagram of data processing proportions of respective first target ground stations according to an embodiment of the present application. Referring to fig. 7, the priority probability of ground station 202 is 46.15% of the sum of the priority probabilities of ground station 202 and ground station 204, and the priority probability of ground station 204 is 53.85% of the sum of the priority probabilities of ground station 202 and ground station 204. Thus, the data processing ratio corresponding to the ground station 202 is 46.15% and the data processing ratio corresponding to the ground station 204 is 53.85%.
Further, the first satellite 10 splits the data corresponding to the source mobile terminal 30 according to the data processing ratio. For example, the first satellite 10 divides the data corresponding to the source mobile terminal 30 into two parts, one part accounting for 46.15% and the other part accounting for 53.85%.
Finally, the first satellite 10 transmits the split data to the corresponding first target ground stations according to the data processing proportion, and the data are respectively processed by the plurality of first target ground stations. For example, the first satellite 10 transmits data to the ground station 202 at a rate of 46.15% and data to the ground station 204 at a rate of 53.85%. Thus, the ground station 202 and the ground station 204 each process the received data.
After processing the respective data, the plurality of first target ground stations transmit the processed data to the target mobile terminal 40. The target mobile terminal 40 then combines the received partial data to generate complete data. For example, the ground station 202 and the ground station 204 process the received data, and then transmit the processed data to the target mobile terminal 40. Further, the target mobile terminal 40 combines the 46.15% data received from the ground station 202 with the 53.85% data received from the ground station 204 to generate complete data.
Therefore, each first target ground station achieves the technical effect of maximally utilizing the data processing capacity of the first target ground station through the operation of processing the data corresponding to the data processing proportion.
Optionally, the operation of determining the plurality of ground stations as the first target ground station and transmitting data corresponding to the source mobile terminal to the target mobile terminal through the first target ground station includes: the first satellite sorts the first target ground stations according to the priority probabilities corresponding to the first target ground stations, and determines the priority order corresponding to the first target ground stations; and the first target ground station will be in order of priority as the order in which data is transmitted to the target mobile terminal.
Specifically, after determining the data processing proportions corresponding to the respective first target ground stations, the first satellite 10 needs to further determine the order of transmitting data corresponding to the respective first target ground stations.
For example, the first satellite 10 determines that the first target ground stations are ground station 202 and ground station 204, and that the priority probability of ground station 202 is 30% and the priority probability of ground station 204 is 35%. So that the priority order of the ground stations 204 is higher than the priority order of the ground stations 202, as known from the priority probabilities of the ground stations 202 and 204. Thus, the ground station 204 first transmits data to the target mobile terminal 40, and then the ground station 202 transmits data to the target mobile terminal 40.
Therefore, by sequencing the first target ground stations according to the priority probability of the first target ground stations and using the sequencing result as the sequence of transmitting data to the target mobile terminal, the technical effect of fully utilizing the data processing performance of the first target ground stations is achieved.
Optionally, the method further comprises: the first satellite broadcasts a data processing request sent by the source mobile terminal and data corresponding to the source mobile terminal to a second satellite, wherein the second satellite is other satellites except the first satellite; the second satellite establishes communication connection with the ground station in the second communication coverage area based on the data processing request, and determines a second target ground station according to a preset priority standard; the second satellite transmits the data corresponding to the source mobile terminal to a second target ground station, and the second target ground station processes the data corresponding to the source mobile terminal; and the second target ground establishes communication connection with the target mobile terminal, and transmits data corresponding to the source mobile terminal to the target mobile terminal.
Specifically, when the source mobile terminal 30 and the target mobile terminal 40 are the same mobile terminal, since the first satellite 10 is in a continuously moving state, the target mobile terminal 40 (i.e., the source mobile terminal 30) may move out of the first communication coverage of the first satellite 10 after receiving the data transmitted by the source mobile terminal 30 and the data processing request, so that the target mobile terminal 40 cannot receive the data corresponding to the source mobile terminal 30. The source mobile terminal 30 and the target mobile terminal 40 may or may not be the same mobile terminal.
Thus, in order to prevent the occurrence of the above, the second satellite 50 may also be provided. Specifically, fig. 8A is a schematic diagram of the target mobile terminal 40 according to the embodiment of the present application not being in the first communication coverage area of the first satellite 10 and being in the second communication coverage area of the second satellite 50. Referring to fig. 8A, the communication coverage of the first satellite 10 is a first communication coverage, and the ground stations within the first communication coverage are a ground station 201, a ground station 202, a ground station 203, and a ground station 204. The communication coverage of the second satellite 50 is a second communication coverage, and the ground stations within the second communication coverage are the ground station 203, the ground station 204, and the ground station 205. Further, the target mobile terminal 40 is not in the first communication coverage but in the second communication coverage. And wherein the source mobile terminal 30 and the target mobile terminal 40 are the same mobile terminal.
Accordingly, as shown in fig. 8A, when the source mobile terminal 30 transmits data to be processed and a data processing request corresponding to the data to the first satellite 10, the first satellite 10 broadcasts the data corresponding to the source mobile terminal 30 and the data processing request to the second satellite 50. The second satellite 50, upon receiving the data corresponding to the source mobile terminal 30 and the data processing request, establishes a communication connection with the ground station 203, the ground station 204, and the ground station 205 within the second communication coverage area.
The second satellite 50 then determines a second target ground station according to the pre-set priority criteria. Wherein the priority criteria of the second satellite 50 are the same as the priority criteria of the first satellite 10 and the manner in which the second satellite 50 determines the second target ground station is also the same as the manner in which the first satellite 10 determines the first target ground station. For example, the second satellite 50 determines the ground station 205 to be a second target ground station based on a pre-set priority criteria.
Further, the second satellite 50 transmits data corresponding to the source mobile terminal 30 to the second target ground station and the second target ground station processes the data corresponding to the source mobile terminal 30.
Finally, the second target ground station establishes a communication connection with the target mobile terminal 40 and transmits data corresponding to the source mobile terminal to the target mobile terminal 40.
Furthermore, although the first satellite 10 is in constant motion, the target mobile terminal 40 does not necessarily move out of the first communication coverage of the first satellite 10. Fig. 8B is a schematic diagram of a target mobile terminal 40 according to an embodiment of the present application being within a first communication coverage area of both a first satellite 10 and a second communication coverage area of a second satellite 50. Referring to fig. 8B, when the target mobile terminal 40 is also within the first communication coverage of the first satellite 10, the target mobile terminal 40 may receive data transmitted by a first target ground station within the first communication coverage or data transmitted by a second target ground station within the second communication coverage.
For example, the first satellite 10 receives the data transmitted from the source mobile terminal 30 and the data processing request, and then broadcasts the data processing request corresponding to the source mobile terminal 30 to the second satellite 50. Then, the first satellite 10 and the second satellite 50 respectively determine that the first target ground station satisfying the requirement is the ground station 202 and determine that the second target ground station satisfying the requirement is the ground station 205 according to the preset priority criteria.
The second satellite 50 then returns the priority probability corresponding to the ground station 205 to the first satellite 10.
Further, the first satellite 10 determines the proportion of the amount of data that needs to be allocated to the second satellite 50 based on the priority probability of the ground station 202 and the priority probability of the ground station 205 within the second communication coverage area of the second satellite 50. As another example, the ground station 202 has a priority probability of 50% and the ground station 205 has a priority probability of 50%, so that the first satellite 10 broadcasts 50% of the data to the second satellite 50.
After receiving 50% of the data, the second satellite 50 transmits the data to the ground station 205, while the first satellite 10 transmits 50% of the data to the ground station 202.
The ground station 202 and the ground station 205 process data corresponding to the source mobile terminal 30, respectively, and transmit the processed data to the target mobile terminal 40.
The target mobile terminal 40 combines the received data transmitted by the ground station 202 with the received data transmitted by the ground station 205 to generate processed data corresponding to the source mobile terminal 30.
Thus, when the target mobile terminal 40 is within the first communication coverage of the first satellite 10 and the second communication coverage of the second satellite 50, the data processing efficiency can be further improved by simultaneously processing the data corresponding to the source mobile terminal 30 by using the first target ground station and the second target ground station that satisfy the condition.
Fig. 8A and 8B show the case where the source mobile terminal 30 and the target mobile terminal 40 are the same mobile terminal. When the source mobile terminal 30 and the target mobile terminal capable terminal 40 are not the same mobile terminal, the operation is the same as described above, and will not be described again here.
Thus, according to the first aspect of the present embodiment, the technical effect that not only a large amount of data can be processed, but also the efficiency of processing the data can be ensured can be achieved.
Further, as shown with reference to fig. 2A and 2B, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium includes a stored program, wherein the method of any one of the above is performed by a processor when the program is run.
