Description

Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communication technology, and in particular to a bearer network path selection method and a bearer network path selection system. Background Technology

[0002] With the rapid development of satellite communication technology, satellite networks are continuously improving their communication capabilities in terms of capacity, speed, latency, and reliability, enabling them to complement and coordinate with terrestrial fixed / mobile networks. Integrated space-ground mobile communication systems have become a global research hotspot in communication technology in recent years and a key development direction for my country's information and communication industry. They are considered by the industry to be one of the main architectural supporting technologies for 5G-A (5G-Advanced, 5G extension and enhancement) and 6G.

[0003] Figure 1 This is a schematic diagram of the architecture of an integrated space-ground mobile communication system. The integrated space-ground mobile communication system consists of a space-based network and a ground-based network. The space-based network includes a space-based access network and a space-based core network; the ground-based network includes a ground-based access network and a ground-based core network, with the ground-based core network further comprising a ground-based public core network and a ground-based satellite core network.

[0004] Existing technologies categorize the implementation solutions for space-based and ground-based networks into the following five types:

[0005] 1) All-Ground Network: The ground network provides all network functions and application services for the terminal.

[0006] 2) Space-based network as pass-through: The space-based network provides pass-through functionality for satellite single-connection / multi-connection terminals and acts as an RF amplifier; the ground-based network provides complete network functions and application services for satellite single-connection / multi-connection terminals, including all functions of the access network (CU+DU), all functions of the core network, related functions of the service platform, and related functions of the data network.

[0007] 3) Space-based network as part / all access network: The space-based network provides access network partial functions (DU) or access network full functions (CU+DU) for satellite single-connection / multi-connection terminals; the ground-based network provides access network partial functions (CU), core network full functions (including satellite interconnection gateway), service platform related functions, and data network related functions for satellite single-connection / multi-connection terminals.

[0008] 4) Space-based network as access network + part / all core network: The space-based network provides all access network functions (CU+DU), part or all core network functions for satellite single-connection / multi-connection terminals; the ground-based network provides part of the core network functions (including satellite interconnection gateway), service platform related functions, and data network related functions for satellite single-connection / multi-connection terminals.

[0009] 5) Space-Ground Integrated Network: The space-based network provides complete network functions and application services for fully connected terminals.

[0010] In existing terrestrial mobile communication systems, the bearer network comprises three parts: fronthaul, midhaul, and backhaul. The fronthaul primarily carries the CPRI (General Public Radio Interface) / ECPRI (Enhanced General Public Radio Interface) interface between the BBU (Building Baseband Unit) and RRU (Remote Radio Unit). The midhaul and backhaul primarily carry N2 / N3 and some N9 traffic, providing connectivity and bandwidth guarantees between the access network and the core network. Therefore, in integrated terrestrial and space-based mobile communication systems, involving terrestrial-space convergence and collaborative interaction between the space-based / terrestrial access network and the space-based / terrestrial core network, the bearer network plays a crucial role in network construction.

[0011] Existing technologies do not consider how to use the space-based bearer network as a partial bearer network to cooperate with the ground-based bearer network to complete service transmission when a part of the ground-based bearer network in a space-ground integrated mobile communication system suffers large-scale damage and is unable to carry out ground transmission.

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the bearer network management and control system architecture for an integrated space-ground mobile communication system according to an embodiment of the present invention. The bearer network management and control system includes: a ground-based bearer network, a space-based bearer network, a ground-based bearer network management and control system, and a space-based bearer network management and control system.

[0068] The ground-based transmission network includes multiple transmission devices that can establish connections with each other to transmit data. The space-based transmission network includes multiple satellites that can establish wireless connections with each other to transmit data.

[0069] The ground-based carrier network control system is used to send control information to the transmission equipment in the ground-based carrier network to achieve control over the transmission equipment. The space-based carrier network control system is used to send control information to the satellites in the space-based carrier network to achieve control over the satellites. The ground-based carrier network control system and the space-based carrier network control system can be two separate control systems, or they can be a unified ground-based and space-based control system. When the ground-based carrier network control system and the space-based carrier network control system are two separate control systems, the carrier network control system also includes a space-based integrated orchestrator, which can coordinate the ground-based carrier network control system and the space-based carrier network control system.

[0070] In this embodiment of the invention, the bearer network management and control system may include one or more ground-based bearer network management and control systems. When there is one ground-based bearer network management and control system, the ground-based bearer network management and control system uniformly manages the transmission equipment in the ground-based bearer network. When there are multiple ground-based bearer network management and control systems, the multiple ground-based bearer network management and control systems can manage the transmission equipment in the ground-based bearer network in different regions.

[0071] In this embodiment of the invention, the bearer network management and control system may include one or more space-based bearer network management and control systems. When there is one space-based bearer network management and control system, the space-based bearer network management and control system uniformly manages the transmission equipment in the space-based bearer network. When there are multiple space-based bearer network management and control systems, the multiple space-based bearer network management and control systems can manage the satellites in the space-based bearer network in different regions.

[0072] When the bearer network management system includes multiple ground-based bearer network management systems, the bearer network management system may further include: a ground-based bearer network orchestrator, which is connected to multiple ground-based bearer network management systems for coordinating the multiple ground-based bearer network management systems.

[0073] In addition, when the bearer network management system includes multiple space-based bearer network management systems, the bearer network management system may also include: a space-based bearer network orchestrator, which is connected to multiple space-based bearer network management systems for coordinating the multiple space-based bearer network management systems.

[0074] The ground-based bearing network arranger and the space-based bearing network arranger can also be connected to the integrated space-ground arranger.

[0075] When the ground-based bearer network management system and the space-based bearer network management system are two separate management systems, a space-ground integrated orchestrator can coordinate the two systems. The ground-based bearer network management system (or ground-based bearer network orchestrator) has the ability to acquire network topology information and other information of the ground-based bearer network within the management area, and to calculate the transmission path of services between transmission devices based on the network topology information and corresponding mechanisms (such as the shortest path principle). It also has the ability to provide the aforementioned network topology information and the calculated transmission path to the superior ground-based bearer network management system or the ground-based bearer network orchestrator.

[0076] The space-based carrier network management and control system has the ability to acquire information such as ephemeris information of satellite networking of the space-based carrier network within the management and control area, and to calculate the transmission path of services between satellites based on the ephemeris information and corresponding mechanisms (such as the shortest path principle). It also has the ability to provide the above-mentioned ephemeris information and the calculated transmission path to the superior space-based carrier network management and control system or space-based carrier network orchestrator.

[0077] Please refer to Figure 3 This invention provides a method for selecting a bearer network path, comprising:

[0078] Step 31: Obtain information on one or more uplink services that need to be transmitted via the space-based bearer network;

[0079] Uplink services refer to services that require transmission via a space-based bearer network. There are two scenarios where services require transmission via a space-based bearer network: either at least one network failure occurs in the ground-based bearer network used to transmit the service, or the user instructs that the service need to be transmitted via a space-based bearer network.

[0080] Step 32: Select a first transmission device as the uplink node of the ground-based bearer network to the space-based bearer network, wherein the first transmission device is the transmission device that can receive the most uplink service messages and has the ability to send the uplink service messages to the space-based bearer network;

[0081] A satellite uplink node refers to the transmission equipment in a ground-based carrier network that sends service information to satellites in a space-based carrier network. Please refer to [reference needed]. Figure 2 The first transmission device may be Figure 2 Transmission device A in the middle.

[0082] The transmission device that can receive the most uplink services is selected as the first transmission device, so that more uplink services can be sent to the satellite through the first transmission device.

[0083] Step 33: Select a second transmission device as the downlink node of the ground-based bearer network to the space-based bearer network, wherein the second transmission device is the transmission device that can transmit the most uplink service messages to the destination node transmission device and has the ability to receive the uplink services sent by the space-based bearer network.

[0084] A satellite node refers to a transmission device in a ground-based carrier network that receives service information transmitted by satellites in a space-based carrier network. Please refer to [link / reference]. Figure 2 The second transmission device may be Figure 2 In the transmission device B, the destination node transmission device can be... Figure 2 The transmission device C in the middle.

[0085] The transmission device that can transmit the most uplink services to the destination node transmission device is selected as the second transmission device, so that more uplink services can be transmitted to the destination node transmission device through the second transmission device.

[0086] Step 34: Provide the location information of the first transmission device and the second transmission device to select the first satellite in the space-based bearer network that communicates with the first transmission device, and the second satellite in the space-based bearer network that communicates with the second transmission device.

[0087] Please refer to Figure 2 The first satellite can be Figure 2 Satellite a, the second satellite could be Figure 2 China Satellite b.

[0088] In this embodiment of the invention, optionally, the above-mentioned method for selecting the bearing network path can be executed by the foundation bearing network management and control system, or by the foundation bearing network orchestrator.

[0089] The location information of the first transmission device and the second transmission device can be provided by the ground-based carrier network management system or the ground-based carrier network orchestrator to the integrated space-ground orchestrator.

[0090] In this embodiment of the invention, a method for determining up-satellite nodes and down-satellite nodes in a ground-based carrier network is provided, thereby enabling the ground-based carrier network and the space-based carrier network to collaboratively complete the transmission of services.

[0091] In this embodiment of the invention, optionally, in step 31 above, obtaining information on one or more uplink services that need to be transmitted via the space-based bearer network includes:

[0092] Step 311: Receive first information sent by the transmission device in the ground-based bearer network. The first information is used to indicate that the transmission device has detected that the service passing through the transmission device cannot be transmitted to the destination node transmission device through the ground-based bearer network, or the transmission device receives user indication information indicating that the service passing through the transmission device needs to be transmitted through the space-based bearer network.

[0093] Step 312: Based on the first information, determine the information of one or more uplink services that need to be transmitted by the space-based bearer network.

[0094] In this embodiment of the invention, optionally, in step 32 above, selecting the first transmission device as the uplink node of the ground-based bearer network to the space-based bearer network includes:

[0095] Step 321: Obtain the original transmission path of the one or more satellite services in the ground-based bearer network;

[0096] Step 322: Select the first transmission device located on the original transmission path of at least one of the above-satellite services as the above-satellite node of the ground-based bearer network to the space-based bearer network.

[0097] In other words, when selecting the first transmission device, if there are multiple transmission devices that can receive the most uplink service messages, then the transmission device located on the original transmission path of at least one uplink service message can be selected as the first transmission device, thereby reducing the detour path of the uplink service message.

[0098] In this embodiment of the invention, optionally, in step 32 above, selecting the second transmission device as the downlink node of the ground-based bearer network to the space-based bearer network includes:

[0099] Step 321: Select the second transmission device located on the original transmission path of at least one of the above-satellite services as the above-satellite node of the ground-based bearer network to the space-based bearer network.

[0100] In other words, when selecting a second transmission device, if there are multiple transmission devices that can transmit the most uplink services to the destination node transmission device, then the transmission device located on the original transmission path of at least one uplink service can be selected as the second transmission device, thereby reducing the detour path of the uplink service.

[0101] In an optional embodiment of the present invention, the bearer network path selection method further includes: transmitting the uplink service whose original transmission path passes through the first transmission device to the first transmission device for transmission through the space-based bearer network.

[0103] In this way, the uplink service that did not pass through the first transmission device in the original transmission path can be transmitted to the first transmission device by means of detour.

[0104] When selecting a new first transmission device for an uplink service whose original transmission path does not pass through the first transmission device, the method of selecting the first transmission device is the same as described above.

[0105] Optionally, in an embodiment of the present invention, the bearer network path selection method further includes: for the uplink service whose original transmission path does not pass through the second transmission device, using the second transmission device as the downlink node of the ground-based bearer network to the space-based bearer network; or, selecting a new second transmission device for the uplink service whose original transmission path does not pass through the second transmission device.

[0106] When selecting a new second transmission device for an uplink service whose original transmission path does not pass through the second transmission device, the method of selecting the second transmission device is the same as described above.

[0107] The methods for selecting the bearer network path in the above embodiments can all be executed by the foundation bearer network management and control system, or by the foundation bearer network orchestrator.

[0108] Please refer to Figure 4 In an optional embodiment of the present invention, the bearer network path selection method further includes:

[0109] Step 35: Obtain the ephemeris information of the satellites in the space-based carrier network;

[0111] Step 37: Based on the ephemeris information, the information of the first satellite, and the information of the second satellite, select the transmission path between the first satellite and the second satellite in the space-based carrier network.

[0112] Steps 35-37 above can be executed by the space-based bearer network management and control system, or by the space-based bearer network orchestrator, or by the integrated space-ground orchestrator.

[0113] In this embodiment of the invention, the method for determining the up-satellite node and down-satellite node in the ground-based carrier network, and the satellite in the space-based carrier network for connecting with the up-satellite node and down-satellite node is given, thereby realizing the collaborative completion of service transmission by the ground-based carrier network and the space-based carrier network.

[0114] Please refer to Figure 5 This invention provides a method for selecting a bearer network path, comprising:

[0119] Step 54: Based on the ephemeris information, the information of the first satellite, and the information of the second satellite, select the transmission path between the first satellite and the second satellite in the space-based carrier network.

[0120] Steps 51-54 above can be executed by the space-based bearer network management and control system, or by the space-based bearer network orchestrator, or by the integrated space-ground orchestrator.

[0121] If executed by the integrated space-ground orchestrator, the ephemeris information of the satellites in the space-based carrier network can be provided to the integrated space-ground orchestrator by the space-based carrier network management system or the space-based carrier network orchestrator.
