Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.
It should be noted that technical terms or scientific terms used in the embodiments of the present application should have a general meaning as understood by those having ordinary skill in the art to which the present application belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the present application is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
As described in the background art, in the process of relative movement of a satellite, establishment of multiple types of services transmitted over a long distance is affected by transmission distance, so that the problems of high transmission delay of the types of services in the transmission process are caused, and the success rate of service establishment is low. The existing method for improving the transmission quality of the satellite network only reestablishes different routes according to the dynamic topology change of the satellite, but the transmission requirements of all services cannot be met only by means of inter-satellite link transmission in some special scenes, and the consideration on the bearable service capability of the satellite network is lacked, so that the service transmission quality cannot be improved, and other channel resources are occupied, and the inter-satellite link is fragmented.
(1) Satellite network
With the support of various technological developments, satellite networks have become an indispensable part of the development of integrated networks, where various service types such as voice, video, data, and broadband multimedia can be carried. The satellite nodes are also important components of a satellite network, dynamic and topological time-varying characteristics of the satellite nodes are always considered, the satellites are mutually connected through inter-satellite links, and the inter-satellite links are switched due to continuous movement of the satellite nodes. In the process of link switching, partial service transmission is interrupted, and the service performance of the service is affected. The user terminal can realize the service requirements of different users through the satellite network by establishing connection between the ground gateway station and the satellite not only through the satellite network but also through the complete space-ground integrated network, and the service transmission quality is influenced by the bearing capacity of the network communication capacity due to uneven geographic population distribution and different service quantity in each satellite network area.
(2) Snapshot techniques in satellite networks
The snapshot technology can acquire the topology condition of the satellite network, and the service transmission interruption caused by the inter-satellite link interruption can be effectively avoided by calculating the route through the stored snapshot. The snapshot overview process is a loop that divides the dynamic topology of a satellite network into a series of topological snapshots by exploiting the predictability and periodicity of satellite motion, and the network topology within each snapshot is considered to be invariant. And uploading the pre-calculated routing table of each snapshot to the satellite node by using the snapshot routing algorithm, and updating the routing table by using the satellite node at the snapshot switching moment. However, the snapshot routing algorithm has the disadvantage of frequent route switching.
(3) Method for establishing satellite-ground link
The satellite and the ground optical communication terminal are connected through a laser link, and the request of the ground user terminal can be transmitted to the satellite through the laser of the ground optical communication terminal to perform on-satellite transmission processing. The process is that when the satellite and the ground terminal enter the link range, the ground terminal carries out coarse aiming respectively, the ground terminal transmits and captures beacon light, the beam divergence angle of the beacon light is at least the capture uncertainty range of the ground light communication terminal, and the satellite terminal carries out capture scanning from inside to outside in a spiral mode within the uncertainty angle range; when the satellite terminal captures the beacon light, a response signal is sent to the ground terminal, and meanwhile, the satellite terminal enters a tracking state; after capturing the response optical signal, the ground optical communication terminal enters a tracking state, so that the laser link between the satellite and the ground optical communication terminal is established.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.

step S101, obtaining traffic of arriving service and link information and service information of a satellite network, wherein the link information comprises satellite-to-ground link information and inter-satellite link information. By acquiring the traffic of the arriving service and the information of the satellite network, the service traffic monitoring based on load sensing is realized. According to the periodic dynamic change of the satellite, the service flow newly arriving at the satellite node can be periodically calculated and monitored by taking the updating time of the satellite network topology as a period. By monitoring the change of the service quantity during each topology updating, different service transmission modes can be selected for different types of services.
And S102, acquiring the bearing capacity of the satellite network based on the link information. The bearing capacity of the satellite network is obtained through the link information, and the bearing capacity can be used as a contrast value of the arriving flow to provide a data basis for the selection of the transmission mode of the subsequent arriving flow.
Step S103, in response to the fact that the bearing capacity does not meet the flow requirement, setting the transmission mode of the arrival service to be transmission through a satellite-to-ground link, and obtaining the type of the arrival service. The transmission mode of the service in the satellite network is selected according to the service flow of the satellite network and the duration of the transmission service, and idle satellite-ground link resources are used as the transmission mode of the network transmission relay, so that the establishment requirements of a large number of services are met, and the sufficient number of services transmitted by the satellite network is ensured.
And S104, establishing a satellite network service corresponding to the arrival service based on the type and the satellite-to-ground link information. The satellite-ground link serves as a service relay for end-to-end transmission in the satellite network, idle satellite-ground link resources are utilized to transmit inter-satellite fragmentation services in the satellite network, and reasonable link allocation and planning are carried out on a large number of services. Therefore, the success rate of service establishment can be effectively improved, channel resources are fully utilized, and the service bearing capacity of the satellite network can be improved.
In some embodiments, the satellite network service establishment method further comprises:
and responding to the fact that the bearing capacity meets the flow requirement, setting the transmission mode of the arrival service to be transmitted through an inter-satellite link, and establishing the satellite network service based on the inter-satellite link information.
Specifically, an inter-satellite link is used as an end-to-end transmission relay of a satellite network, and real-time reliable satellite network service is established for arrival flow. The inter-satellite link refers to a link for communication between satellites, and can interconnect multiple satellites together to realize information transmission and exchange between the satellites. On the inter-satellite link, large-capacity data transmission can be realized through optical communication. Due to the introduction of the inter-satellite link, the low-earth-orbit satellite mobile communication system can depend on a ground network less, so that the low-earth-orbit satellite mobile communication system can perform routing selection and network management more flexibly and conveniently; meanwhile, the number of ground gateways is reduced, so that the complexity and investment of ground sections can be greatly reduced.

And the size of the service flow which can be carried by the satellite network is used as a contrast value of the transmission arrival service flow in the network. With the dynamic change of the satellite, the topology changes periodically, and the topology of the satellite network, the link information and the arrival service flow are updated by taking one topology updating as a period. By monitoring the change of the service quantity during each topology updating, different service transmission modes can be selected for different types of services.
In some embodiments, referring to fig. 3, step 103 specifically includes:
step S1031, obtaining the transmission duration of the arrival service based on the service information of the current period;

Different traffic types arriving at the satellite nodes are collected. Service information transmitted between the satellites is obtained, and the duration of transmission of various services is judged and classified. If available satellite-ground link resources exist, the services are divided according to the transmission duration, the service with long transmission duration still adopts an inter-satellite link as a transmission mode, and the service with short transmission duration selects a satellite-ground link as a transmission relay of the service. And judging the transmission duration of the arrival service in the current period through the service transmitted among the satellites, and taking the transmission duration as a data basis for subsequently selecting the transmission duration of the idle satellite-ground link.

And judging the acquired occupation states of all satellite-ground link resources according to the condition that the service occupies the bandwidth in the satellite-ground link. If idle satellite-ground link resources exist, the idle satellite-ground link resources can be used as transmission relays of the inter-satellite fragmentation resources. And comparing and selecting the available idle planet ground link resources, and comparing the residual duration of the establishment of each idle planet ground link. And comparing the residual duration time established by the idle satellite-ground link, and selecting the satellite-ground link resource with long residual duration time as the relay of end-to-end transmission. The spare satellite-ground link is used as a relay to transmit fragmented services of inter-satellite links, so that the success rate of service establishment in the satellite network is ensured, and the problem of overlarge service flow in the satellite network is solved.
In some embodiments, the satellite-to-ground link information includes an idle satellite-to-ground link and satellite information corresponding to the idle satellite-to-ground link.
Specifically, a laser link between the satellite and the ground optical communication terminal is established through the idle satellite-ground link and the satellite information corresponding to the idle satellite-ground link, and the idle satellite-ground link can be used for converting the transmitted service information through a ground gateway station switching technology and selecting a proper transmission channel, so that the whole satellite network can support the continuously increased service flow, and the service carrying capacity of the network is improved.
In some embodiments, step S1043 specifically includes:
and sequencing the idle satellite-ground links from long to short according to the idle time corresponding to the idle satellite-ground links in the satellite-ground link information of the previous period, establishing the satellite network service corresponding to the arrival service of the fragmentation type based on the first N idle satellite-ground links in the sequencing result and the satellite information corresponding to the idle satellite-ground links, wherein N represents the minimum number of the idle satellite-ground links capable of establishing the satellite network service.
Specifically, a spare satellite-ground link is searched, and the satellite-ground link with long residual duration established by the link is used as a transmission relay of the service in the satellite network. Therefore, the success rate of service establishment can be effectively improved, channel resources are fully utilized, and the service bearing capacity of the satellite network can be improved.

The satellite network of fig. 5 is a network of low earth orbit satellites in which there are multiple inter-satellite link resources available. When a large amount of services arrive, the bearable service capability of the satellite network cannot meet the establishment of the large amount of services, so that the services are congested or lost in the inter-satellite link transmission process, and the services are fragmented in the inter-satellite link transmission process.
