Description

Technical Field

[0001] This application relates to the field of satellite communication technology, and particularly to a communication service simulation system and method in a high-throughput satellite simulation network. Background Art

[0002] With the continuous progress of technology and the expansion of application scenarios, satellite networks have gradually developed from small-scale, low-throughput transparent repeater satellites to high-throughput satellites and high-throughput satellite constellations.

[0003] In high-orbit communication satellites, the current "simulation method and system for a mobile satellite network" has realized the communication service scheme of "satellite node relay", and does not support the communication service simulation of "satellite + ground station relay" for high-throughput satellites. In addition, the service flow supported by the communication service scheme of "satellite node relay" is as follows: the service flow goes to the satellite once and is not forwarded to the ground station, but is directly forwarded to the destination node at the satellite node. The service flow supported by high-orbit high-throughput communication satellites is as follows: after the first time going to the satellite, it is forwarded to the ground station, goes to the satellite twice through the ground station, and then flows to the destination node. Using the communication service simulation scheme of "satellite node relay" for high-orbit high-throughput satellites will result in problems such as inconsistent actual service paths and simulation service paths, and inconsistent link traffic.

[0045] In an embodiment of the present application, the operating environment of the communication service simulation system in the high-throughput satellite simulation network is composed of network nodes and the links between nodes.

[0046] Among them, the network nodes include terminals, satellites, ground stations, and ground network nodes, which are simulated by a combination of routing and switching containers + specific containers, and are provided with network interfaces for routing information calculation and traffic service forwarding. Among them, the network node types and network node locations are consistent with those in the satellite network.

[0047] The inter-node links include high-throughput satellite-ground station links, terminal-high-throughput satellite links, ground station-ground station node links, and ground network links, which are simulated by virtual switches, connect all node network interfaces, and are used for inter-node connection, link delay, and error simulation. Among them, the connection relationship, delay, and error of the inter-node links are consistent with the attributes of the inter-node links in the high-throughput satellite network.

[0048] In the embodiments of this application, the high-throughput satellite communication service simulation includes three parts: high-throughput satellite terminals, high-throughput satellite base stations, and high-throughput core networks. Among them, the high-throughput satellite terminals are simulated by containers, are connected to the virtual switch through interfaces, and access the satellite, and are used to complete terminal network access and service generation. That is, the satellite terminals are simulated by containers and mainly complete functions such as terminal network access and service generation; the high-throughput satellites are simulated by containers, are connected to the virtual switch through one interface to access the terminals, and are connected to the virtual switch through another interface to access the ground stations; the ground stations are simulated by containers; the high-throughput satellite base stations are simulated by containers and are connected to the ground stations through interfaces, and are used to complete terminal network access and service generation. That is, the satellite base stations are simulated by containers and mainly complete functions such as terminal access, satellite resource management and allocation, and service forwarding; the high-throughput core networks are simulated by containers, are connected to the virtual switch through interfaces, and access the ground stations, and are used to complete terminal management and service management.

[0049] The specific deployment plan is as follows: 1. The high-throughput satellite terminals are simulated by containers and are connected to the virtual switch through interfaces to access their respective high-throughput satellites;

[0050] 2. The high-throughput satellites are simulated by routing and switching containers, are connected to the virtual switch through one interface to access the terminals, and are connected to the virtual switch through another interface to access the ground stations;

[0051] 3. The ground stations are simulated by routing and switching containers, and the high-throughput satellite base stations are simulated by containers and are connected to the ground stations through interfaces;

[0053] Specifically, the high-throughput satellite communication service simulation process includes: management process, control process, and service process.

[0054] Among them, the management process: Taking the satellite terminal initiating the network access process as an example, the management flow path is introduced.

[0055] The terminal network access message sent by the satellite terminal is sent to the corresponding high-throughput satellite. The high-throughput satellite forwards the terminal network access message to the satellite base station container of the ground station. After being processed by the satellite base station container, it is forwarded to the core network to realize the network access of the satellite terminal.

[0056] Among them, the control process: Taking the satellite terminal initiating a service call as an example, the control flow path is introduced.

[0057] The service call process includes four segments: satellite terminal 1 and satellite base station 1 of the ground station; satellite base station 1 of the ground station and the core network; the core network and satellite base station 2 of the ground station; satellite base station 2 of the ground station and satellite terminal 2.

[0058] Satellite terminal 1 and satellite base station 1 of the ground station: There is a high-throughput satellite intermediate node in the middle, and the control path is satellite terminal 1 → accessed high-throughput satellite → (ground station) satellite base station 1.

[0059] Satellite base station 1 and the core network: In the middle, it passes through the terrestrial network or satellite network, which is determined by the routing and can be simplified to obtain through traceroute.

[0060] The core network and satellite base station 2: Similar to the case of satellite base station 1 and the core network, it is determined by the routing and can be simplified to obtain through traceroute.

[0061] Satellite base station 2 and satellite terminal 2: Similar to "satellite terminal 1 and satellite base station 1", it only includes an intermediate node of a high-throughput satellite.

[0062] Among them, the service process: Taking the voice process as an example, the service flow path is introduced.

[0063] The entire service process is divided into three segments: satellite terminal 1 and satellite base station 1; satellite base station 1 and satellite base station 2; satellite base station 2 and satellite terminal 2.

[0064] Satellite terminal 1 and satellite base station 1: The same as the control process "satellite terminal 1 and satellite base station 1".

[0065] Satellite base station 1 and satellite base station 2: In the middle, it passes through the terrestrial network or satellite network, which is determined by the routing and can be obtained through traceroute.

[0066] Satellite base station 2 and satellite terminal 2: Similar to "satellite terminal 1 and satellite base station 1", it only includes an intermediate node of a high-throughput satellite.

[0067] Corresponding to the above system embodiment, this specification also provides an embodiment of a method for simulating communication services in a satellite simulation network. Figure 2This is a schematic flowchart of a method for simulating communication service management flow in a satellite simulation network provided by an embodiment of the present application. As Figure 2 shown, the specific process is as follows.

[0068] Step S101: In the simulation of high-throughput satellite communication services, when the high-throughput satellite receives an access request initiated by a satellite terminal, send the access request to the container of the satellite base station of the ground station;

[0069] Step S102: The satellite base station container processes the access request initiated by the satellite terminal and forwards the processed access request to the core network;

[0070] Step S103: The core network processes the access request initiated by the satellite terminal, generates an access request response, and forwards the access request response to the satellite base station container;

[0071] Step S104: The satellite base station container processes the access request response initiated by the core network to the satellite terminal and forwards the processed access request response to the satellite terminal.

[0072] Figure 3 This is a schematic flowchart of a method for simulating communication service control flow in a satellite simulation network provided by an embodiment of the present application. As Figure 3 shown, the specific process is as follows.

[0073] Step S201: In the simulation of high-throughput satellite communication services, when the satellite terminal completes access registration, the first satellite terminal initiates a service call request and sends the service call request to the high-throughput satellite node for processing;

[0074] Step S202: The high-throughput satellite node forwards the service call request to the container of the satellite base station of the ground station for processing through routing;

[0075] Step S203: The satellite base station container processes the service call request initiated by the first satellite terminal, completes satellite resource allocation, and forwards the processed service call request to the core network to execute the service call;

[0076] Step S204: The core network processes the received service call request and forwards the processed service call to the satellite base station container to which the second satellite terminal belongs;

[0077] Step S205: The satellite base station container to which the second satellite terminal belongs processes the received service call request, completes satellite resource allocation, and forwards the service call to the high-throughput satellite node connected to the second satellite terminal;

[0078] Step S206: The high-throughput satellite node forwards the service call request to the second satellite terminal for processing through routing and forwarding.

[0079] In practical applications, in high-throughput satellite communication service simulation, when the first high-throughput satellite receives a service call request initiated by the first satellite terminal, the service call request is sent to the first satellite base station container of the ground station to which the first satellite terminal belongs; the first satellite base station container processes the service call request initiated by the first satellite terminal, and forwards the processed service call request to the core network to execute the service call; the core network processes the service call request initiated by the first satellite terminal, and forwards the processed service call request to the second satellite base station container to which the second satellite terminal belongs; the second satellite base station container processes the service call request initiated by the first satellite terminal, and forwards the processed service call request to the second high-throughput satellite; the second high-throughput satellite forwards the service call request initiated by the first satellite terminal to the second satellite terminal.

[0080] Figure 4 It is a flowchart showing the simulation method of communication service traffic in a satellite simulation network provided by an embodiment of the present application. As Figure 4 shown, it specifically includes the following processes.

[0081] Step S301: In high-throughput satellite communication service simulation, when the first satellite terminal and the second satellite terminal complete a service call, the first satellite terminal initiates a service data packet and sends the service data packet to the high-throughput satellite node for processing;

[0082] Step S302: The high-throughput satellite node forwards the service data packet to the container of the satellite base station of the ground station for processing through routing and forwarding;

[0083] Step S303: The satellite base station container processes the service data packet initiated by the first satellite terminal, and forwards the processed service data packet to the satellite base station container to which the second satellite terminal belongs;

[0084] Step S304: The satellite base station container to which the second satellite terminal belongs processes the received service data packet, and forwards the service data packet to the high-throughput satellite node connected to the second satellite terminal;

[0085] Step S305: The high-throughput satellite node forwards the service data packet to the second satellite terminal for processing through routing and forwarding.

[0086] In practical applications, in the simulation of high-throughput satellite communication services, when the first high-throughput satellite receives a communication service data packet initiated by the first satellite terminal, the communication service data packet is sent to the first satellite base station container to which the first satellite terminal belongs at the ground station; the first satellite base station container processes the communication service data packet initiated by the first satellite terminal, and forwards the processed communication service data packet to the second satellite base station container to which the second satellite terminal belongs; the second satellite base station container processes the communication service data packet initiated by the first satellite terminal, and forwards the processed communication service data packet to the second high-throughput satellite; the second high-throughput satellite forwards the communication service data packet initiated by the first satellite terminal to the second satellite terminal.

[0087] The technical key points of the present invention are as follows: 1. The high-throughput satellite node, satellite terminal node, and ground station node are simulated based on the routing and switching container; 2. The link between nodes is simulated by a virtual switch to realize the simulation of link on / off, delay, and error code; 3. The simulation of the communication service path is realized by the reasonable deployment of terminals, base stations, and core networks, and the message sending and receiving between nodes, and the path between nodes is realized by routing forwarding; 4. The satellite base station container is deployed at the high-throughput ground station to realize the simulation of the high-throughput satellite's second uplink.

[0088] The high-throughput satellite network communication service simulation method proposed by the present invention has the following advantages: 1. Based on the models of terminals, base stations, core networks, and routing and switching nodes in the terrestrial communication network, the simulation of management flow, control flow, and service flow among multiple nodes including terminals, satellites, ground stations, and terrestrial networks is constructed to realize the transfer of data packets along the paths of satellite network nodes; 2. The simulation of links is realized between nodes through a virtual switch, which can dynamically and flexibly support the simulation of link characteristics, improving the simulation accuracy and confidence of link traffic, delay, and error code in the satellite simulation network; 3. By deploying the base station container to the ground station, the simulation of the high-throughput second uplink is realized.

[0089] Correspondingly, this application provides two embodiments.

[0090] Example 1: Simulation of single high-throughput satellite communication service. Refer to Figure 5 , Figure 5 which is a schematic diagram of the simulation of single high-throughput satellite communication service in a single high-throughput satellite simulation network provided for the example of this application.

[0091] Example 2: Simulation of multi-satellite communication service of high-throughput satellite constellation. Refer to Figure 6 , Figure 6 which is a schematic diagram of the simulation of multi-high-throughput satellite communication service in the multi-satellite communication service of a high-throughput satellite constellation simulation network provided for the embodiment of this application.

[0092] High-throughput satellite communication services have a large business scale, and all service traffic will pass through ground stations for secondary satellite uplink processing. The high-throughput satellite communication service simulation uses three mirrors, namely "terminal", "base station", and "core network", for node simulation, and the connection relationship between the three is simulated through a virtual switch for link simulation. The specific simulation method is as follows: The high-throughput satellite is simulated using the "FRRouting" container; the ground station is simulated using the "FRRouting" + "base station" container; the terminal is simulated using the "OVS" + "terminal" container; the core network is simulated using the "core network" container. The connection relationship is: "terminal" container → "terminal-OVS" container → virtual switch → high-throughput satellite "FRRouting" container → virtual switch → ground station "FRRouting" container → ground station "base station" container → virtual switch → "core network" container. Without considering the link simulation of the virtual switch, the management flow, control flow, and service flow between containers are as follows:

[0093] 1) Management and control flow simulation: For communication services, there are only two process simulations, namely between the terminal and the base station, and between the base station and the core network. The simulation process is achieved through the interaction of the control flows of the "terminal" container and the "base station" container, and the interaction of the control flows of the "base station" container and the "core network" container. The paths between the "terminal" container and the "base station" container, and between the "base station" container and the "core network" container are calculated according to routing to achieve the path and control simulation of "terminal" → "satellite" → "ground station" → "core network".

[0094] 2) Service flow simulation: For communication services, there are only two process simulations, namely between the terminal and the base station, and between the base station and another base station. The simulation process is achieved through the interaction of the service flows of the "terminal" container and the "base station" container, and the interaction of the service flows of the "base station" container and another "base station" container. The paths between the "terminal" container and the "base station" container, and between the "base station" container and another "base station" container are calculated according to routing to achieve the path and service simulation of "terminal" → "satellite" → "ground station" → "ground station" → "satellite" → "terminal".

[0095] 3) Communication service simulation: According to the classification of communication service types, it is realized by using management and control flow simulation and service flow simulation respectively. The main processes are as follows: The terminal network access process uses management and control flow simulation; the terminal call process uses management and control flow simulation; the terminal service communication process uses service flow simulation; the terminal hang-up process uses management and control flow simulation; the terminal network disconnection process uses management and control flow simulation.
