Detailed Description
In this embodiment, the control method of the communication remote sensing integrated satellite may be applied to the satellite communication system shown in fig. 1. Referring to fig. 1, the satellite communication system comprises communication remote sensing integrated satellites, user terminals, gateway stations, remote sensing data receiving and processing centers, a 5G core network, a data network, a network control center and other nodes.
The communication remote sensing integrated satellite is a satellite integrating a communication function and a remote sensing function, and some technologies integrate the communication function, the navigation function and the remote sensing function into the same satellite, which is called as a communication remote sensing integrated satellite in this embodiment, and the communication remote sensing integrated satellite can be used as the communication remote sensing integrated satellite in this embodiment.
In fig. 1, a plurality of communication remote sensing integrated satellites operating in space are connected through inter-satellite links, the communication remote sensing integrated satellites are connected with gateway stations on the ground through feed links, and the communication remote sensing integrated satellites are connected with user terminals (particularly, mobile phones or special communication terminals) on the ground through user links. The gateway station is respectively connected with the remote sensing data receiving and processing center, the 5G core network and the network control center (Network Control Center, NCC). The data network connected with the 5G core network can support the communication function of the communication remote sensing integrated satellite; the remote sensing data receiving and processing center can support the remote sensing function of the communication remote sensing integrated satellite; the network control center can control the operation of the communication remote sensing integrated satellite, for example, control the communication remote sensing integrated satellite to orbit.
The communication remote sensing integrated satellite has a communication function and a remote sensing function, and has the capability of simultaneously executing a communication task and a remote sensing task, or switching from executing the communication task to executing the remote sensing task, or switching from executing the remote sensing task to executing the communication task.
In this embodiment, referring to fig. 2, the control method of the communication remote sensing integrated satellite includes the following steps:
s1, acquiring a remote sensing task;
s2, detecting communication tasks currently executed by a plurality of communication remote sensing integrated satellites;
s3, determining part of communication remote sensing integrated satellites from a plurality of communication remote sensing integrated satellites according to the remote sensing tasks and the communication tasks, and taking the part of communication remote sensing integrated satellites as target satellites;
s4, controlling the target satellite to execute the remote sensing task.
In this embodiment, step S1 may be performed by the remote sensing data receiving and processing center. The remote sensing data receiving and processing center receives the remote sensing task request and generates a remote sensing task according to the remote sensing task request. The remote sensing task comprises information such as the position and time (starting time and remote sensing duration) of a remote sensing imaging target.
In this embodiment, step S2 may be performed by the core network. In step S2, the detected plurality of remote sensing integrated satellites may be all remote sensing integrated satellites capable of being controlled by the network control center. These communication telemetry integration satellites may be performing respective communication tasks. For one of the communication remote sensing integrated satellites, the communication tasks performed by the communication remote sensing integrated satellite can be the following processes: the communication remote sensing integrated satellite and the user terminal are connected through a user link, and an inter-satellite link is established through a route, and the communication remote sensing integrated satellite is used as a node in the inter-satellite link, so that the user terminal can be connected to a gateway station through the user link, the inter-satellite link and a feed link in sequence, finally access to a 5G core network, and the 5G core network provides communication services (such as voice call services) for the user terminal.
In this embodiment, when executing step S2, that is, the step of detecting the communication task currently executed by the plurality of communication remote sensing integrated satellites, the core network may specifically execute the following steps:
s201, detecting operation parameters of each communication remote sensing integrated satellite;
s202, sequencing each communication remote sensing integrated satellite according to the adaptability of each operation parameter relative to a remote sensing task;
s203, determining a plurality of communication remote sensing integrated satellites with the forefront sequence as candidate satellites;
s204, detecting the communication tasks currently executed by the candidate satellites.
In step S201, the core network may query the network control center for the operation parameters of each remote sensing integrated communication satellite. The operation parameters may include data such as task time, target information, relative distance during the task, relative angle, relative angular velocity, solar light angle, lunar light angle, ephemeris data, etc., and these data may be stored in the form of vectors.
In step S202, the core network may acquire a remote sensing task, specifically, information such as a remote sensing imaging target position and time from a remote sensing data receiving and processing center. Data in the telemetry task may also be stored in the form of vectors. In executing step S202, the core network may calculate, through a vector similarity algorithm, the similarity between the operation parameters (in vector form) of each communication remote sensing integrated satellite and the remote sensing data (in vector form), where the similarity between one operation parameter and the remote sensing data may indicate the adaptability of the operation parameter with respect to the remote sensing task, for example, the higher the similarity, the more suitable the communication remote sensing integrated satellite having the operation parameter is for executing the remote sensing task.
In step S202, the remote sensing integrated satellites may be ordered according to the order of the corresponding similarity from high to low.
In step S203, the core network determines a plurality of communication remote sensing integrated satellites in the first sequence among the communication remote sensing integrated satellites sequenced in step S202 as candidate satellites, so as to select the communication remote sensing integrated satellite most suitable for executing the remote sensing task.
In step S204, the core network may detect only the communication tasks performed by the communication telemetry integrated satellite determined as the candidate satellite. Specifically, the core network may detect the service type, the user terminal ID, the link parameters (including parameters of the user link, the inter-satellite link, and the feeder link used for the communication task) of the communication task currently carried by each candidate satellite, and so on.
In this embodiment, step S3 may be performed by the core network. The core network may specifically perform the following steps when executing step S3, that is, determining a part of the communication remote sensing integrated satellites from the plurality of communication remote sensing integrated satellites according to the remote sensing task and each communication task, as the target satellite:
s301, determining a first inter-satellite link existing in each candidate satellite according to the communication task currently executed by each candidate satellite;
s302, executing a routing algorithm according to the operation parameters of each candidate satellite, and determining a second inter-satellite link;
s303, performing complementary set operation for solving an intersection set on the node set in the first inter-satellite link and the node set in the second inter-satellite link;
s304, when the node set obtained after the operation of the first inter-satellite link and the second inter-satellite link is a non-empty set, using the candidate satellite in the node set obtained after the operation as a target satellite;
s305, when the node set obtained after the operation of the first inter-satellite link and the second inter-satellite link is an empty set, respectively determining the operation parameters of each candidate satellite after being loaded with the remote sensing task;
s306, executing a routing algorithm according to the operation parameters of each candidate satellite after being loaded with the remote sensing task, and determining a third inter-satellite link;
s307, performing complementary set operation for solving the intersection set on the node set in the third inter-satellite link and the node set in the third inter-satellite link;
s308, when the node set obtained after the operation of the first inter-satellite link and the third inter-satellite link is a non-empty set, using the candidate satellite in the node set obtained after the operation as a target satellite.
The communication tasks currently performed by each candidate satellite need to be performed over an inter-satellite link. Since the communication tasks currently performed by the candidate satellites may not be identical, a specific communication task is illustrated in steps S301 to S308.
In step S301, for a particular communication task, a first inter-satellite link actually used by the communication task is determined. Referring to fig. 3, among the candidate satellites shown in A, B, C, D, E, F, G and H, the candidate satellite A, D, G, H connected by the dotted line constitutes a first inter-satellite link indicating that data generated by the communication task is transmitted through the first inter-satellite link A, D, G, H.
In step S302, the core network executes a routing algorithm according to the operation parameters such as the relative angle, the relative angular velocity, the sun illumination angle, the moon illumination angle, the ephemeris data, and the like of each candidate satellite, so as to determine a second inter-satellite link that can be used by the communication task. Referring to fig. 4, according to the result of the execution of the routing algorithm, a second inter-satellite link composed of candidate satellites B, D, G, F connected by solid lines is determined, which represents data generated by a communication task carried by the first inter-satellite link, and may also be switched to be transmitted by the second inter-satellite link B, D, G, F.
In step S303, the node set in the first inter-satellite link is { A, D, G, H }, the node set in the second inter-satellite link is { B, D, G, F }, and the intersection between the node set in the first inter-satellite link and the node set in the second inter-satellite link is { D, G }, which is determined by performing the intersection calculation. The node set { A, B, F, H } obtained after the operation can be determined by performing the complement operation on the intersection { D, G } with the union { A, B, D, G, F, H } of the node set in the first inter-satellite link and the node set in the second inter-satellite link as the complete set. In step S304, one or more candidate satellites may be selected from the node set { A, B, F, H } as target satellites, for example, candidate satellite B may be selected as target satellite.
The principle of steps S301-S304 is that: the first inter-satellite link is an inter-satellite link actually used by a specific communication task, the second inter-satellite link is an inter-satellite link which can be used by the same communication task, the second inter-satellite link can be used as a backup of the first inter-satellite link, namely, the first inter-satellite link can be switched to the second inter-satellite link to bear the same communication task, the intersection of the node set in the first inter-satellite link and the node set in the second inter-satellite link is a candidate satellite which needs to continuously execute the communication task before and after switching, and the complement of the intersection is a candidate satellite which only executes the communication task before or after switching, so that the candidate satellite in the complement can avoid executing the communication task through switching or not switching the inter-satellite link, the candidate satellite in the complement releases or does not execute the communication task, the candidate satellite in the complement has small influence on maintaining the communication task, the candidate satellite in the complement is selected as a target satellite, and when the target satellite executes the remote sensing task, if the communication task needs to be released, the communication task is less influenced, and the remote sensing task is realized.
If the second inter-satellite link is the same as the first inter-satellite link as determined by the routing algorithm in step S302, then in step S303, a complement operation for the intersection is performed on the node set in the first inter-satellite link and the node set in the second inter-satellite link, and the result is an empty set. In this case, steps S305 to S308 may be performed.
In step S305, the core network obtains actual operation parameters of each candidate satellite, and simulates to obtain predicted operation parameters of each candidate satellite, where one of the predicted operation parameters of each candidate satellite is a simulation process, loads a remote sensing task on the candidate satellite, and calculates the operation parameters obtained by the candidate satellite in a simulation manner.
In step S306, a routing algorithm is executed according to the predicted operation parameter, which is the operation parameter of each candidate satellite after being loaded with the remote sensing task, according to a process similar to step S302, and a third inter-satellite link output by the routing algorithm is obtained.
In step S307, a complementary set operation for obtaining the intersection is performed on the node set in the third inter-satellite link and the node set in the third inter-satellite link according to a similar procedure to step S303. Since the third inter-satellite link is obtained by routing the operation parameters (i.e. the operation parameters are changed) of each candidate satellite after the remote sensing task is loaded, the third inter-satellite link is generally different from the first inter-satellite link, and in step S308, the node set obtained by calculating the first inter-satellite link and the third inter-satellite link will be a non-empty set, so that the candidate satellite in the node set obtained by calculating can be used as the target satellite.
The principle of steps S305-S308 is that: under the condition that the target satellite cannot be determined according to the first inter-satellite link and the second inter-satellite link, each candidate satellite is simulated, and then the inter-satellite link, namely the third inter-satellite link, possibly used for executing the communication task after each candidate satellite executes the remote sensing task is predicted, so that the target satellite can be determined according to the first inter-satellite link and the third inter-satellite link according to the principle of the steps S301-S304, wherein the influence of the candidate satellite on the communication task when executing the remote sensing task according to the target satellite determined by the first inter-satellite link and the third inter-satellite link is considered, and therefore, when executing the remote sensing task by using the target satellite determined by the steps S305-S308, the influence on the maintenance of the communication task is smaller than when executing the remote sensing task according to the target satellite determined by the steps S301-S304.
In this embodiment, step S4 may be performed by the telemetry data receiving and processing center. When the remote sensing data receiving and processing center performs step S4, that is, the step of controlling the target satellite to perform the remote sensing task, the following steps may be specifically performed:
S401A, detecting the urgency of a communication service currently executed by a target satellite;
S402A, when the degree of urgency is lower than a threshold value, intercepting uplink communication data and downlink communication data transmitted by a target satellite; the uplink communication data and the downlink communication data are generated by the communication service currently executed by the target satellite;
S403A, loading a remote sensing task to a target satellite;
S404A, receiving uploaded remote sensing data of a target satellite;
S405A, when the target satellite finishes uploading the remote sensing data, the target satellite resumes transmitting the uplink communication data and the downlink communication data.
Steps S401A-S405A are the first implementation of step S4. The flow of steps S401A-S405A is shown in fig. 5. Referring to fig. 5, by executing steps S401A to S402A, communication services with low urgency are screened out, and uplink communication data and downlink communication data generated by the transmission of these communication services by the target satellite are intercepted. Specifically, the core network may generate a NAS message, add an N2-UP-service message to the NAS message, and send the NAS message to a user terminal of a communication service with low emergency, so that the user terminal no longer sends uplink communication data to the target satellite.
By executing steps S401A-S402A, non-emergency communication traffic performed by the target satellite may be suspended (the target satellite may exit the inter-satellite link used by the non-emergency communication traffic, re-route a new inter-satellite link to perform the non-emergency communication traffic), thereby freeing up resources of the target satellite in preparation for the target satellite to perform the remote sensing task in steps S403A-S404A.
In steps S403A-S404A, referring to fig. 6, the remote sensing data receiving and processing center issues a remote sensing task to the target satellite, the network control center NCC controls the target satellite to orbit, the target satellite executes the remote sensing task to obtain remote sensing data, and uploads the remote sensing data to the remote sensing data receiving and processing center. In step S405A, after the target satellite finishes uploading the remote sensing data, that is, after the remote sensing task is finished, the target satellite may be reloaded with the originally executed non-emergency communication service, and the target satellite may be restored to transmit the uplink communication data and the downlink communication data.
By executing steps S401A-S405A, the resource of the target satellite for executing the communication service with low urgency can be released, so as to execute the remote sensing task with higher priority and larger data volume, thereby guaranteeing the execution of the remote sensing task.
In this embodiment, step S4 may be performed by the telemetry data receiving and processing center. When the remote sensing data receiving and processing center performs step S4, that is, the step of controlling the target satellite to perform the remote sensing task, the following steps may be specifically performed:
S401B, detecting a feeder link load generated by a communication service currently executed by a target satellite;
S402B, when the load of the feed link reaches a threshold value, modifying a user plane function address corresponding to the target satellite;
S403B, adjusting the communication service currently executed by the target satellite to fall to the ground through the new gateway station;
S404B, loading the remote sensing task to a target satellite;
S405B, receiving the uploaded remote sensing data of the target satellite.
Steps S401B-S405B are the second implementation of step S4. The flow of steps S401B-S405B is shown in fig. 7. Referring to fig. 7, in step S401B, a gateway station connected to a communication service currently executed by a target satellite detects a feeder link load generated by the communication service currently executed by the target satellite.
In step S402B, it is determined whether the feeder link load obtained in step S401B reaches a threshold, and when the feeder link load reaches the threshold, it may be determined that the feeder link load is larger, and the current gateway station may modify the user plane function address corresponding to the target satellite through the extended NGAP flow, so that the target satellite is connected to the gateway station corresponding to the modified user plane function address, that is, the new gateway station is.
In step S403B, the communication service currently executed by the target satellite is adjusted to land through the new gateway station, so that the feeder link load of the current gateway station is reduced.
The principle of steps S404B-S405B is the same as steps S403A-S404A. In steps S404B-S405B, referring to fig. 6, the remote sensing data receiving and processing center issues a remote sensing task to the target satellite, the network control center NCC controls the target satellite to orbit, the target satellite executes the remote sensing task to obtain remote sensing data, and uploads the remote sensing data to the remote sensing data receiving and processing center.
