[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0033] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0034] In addition, the terms "including" and "having" in the embodiments, claims and drawings of the present application are not exclusive. For example, a process, method, system, product or device including a series of steps or modules is not limited to the listed steps or modules, and may also include steps or modules that are not listed.

[0035] In order to facilitate the understanding of the present application, the relevant elements involved in the present application are now described.

[0036] In order to better adapt to the future society's requirements for global ubiquitous access and wide-area intelligent interconnection of all things, and to ensure the continuity and consistency of user services, all walks of life are actively promoting the integration of ground mobile communication networks and satellite communication networks. As a new type of network architecture, the satellite-ground fusion network system can connect satellites, ground terminals and network equipment to each other, and can achieve high-speed data transmission and high-reliability communication on a global scale. It has been widely used in military communications, meteorological monitoring, marine exploration, transportation, logistics and other fields. The satellite-ground fusion network aims to provide real-time, reliable, on-demand consistency services to various users by giving full play to the respective advantages of satellite and ground information technology. Its main application scenarios have been further expanded from typical scenarios such as wide-area coverage and emergency communications to emerging businesses such as artificial intelligence and smart cities, which put forward diverse requirements for the network, such as low latency, high reliability, high energy efficiency and ultra-high density connection.

[0037] The satellite-ground fusion network has the characteristics of wide satellite coverage and no geographical restrictions, and can provide reliable communication services in remote areas and harsh environments. At the same time, the satellite-ground fusion network also has the characteristics of highly dynamic topology, high differences in satellite and ground capabilities, and strong resource constraints, making it difficult to guarantee low-latency, high-reliability, and consistent differentiated network services. Therefore, it is necessary to explore the quality of service (QoS) guarantee and policy control solutions in the satellite-ground fusion network to improve the stability and reliability of the satellite-ground fusion network when providing services.

[0038] At present, service quality assurance solutions are only applied to single-architecture network environments such as ground mobile. With the evolution of the network architecture of the sixth-generation mobile communication technology (6G), there is no mature service quality assurance system or solution for converged network scenarios such as satellite-ground convergence and heterogeneous networks.

[0039] In existing mobile communication systems, due to the good stability of mobile communication networks, the service quality assurance system mainly relies on the issuance of core network policy control rules and performs service quality assurance based on set specific unified control rules.

[0040] In the satellite-ground fusion network system, due to its limited network resources, strong network time-varying characteristics, and the need for coordinated scheduling of multi-dimensional network resources, which are different from the ground mobile communication network, the characteristics of the satellite-ground fusion network must be fully considered in the service quality assurance system, and the satellite-ground fusion network scenarios and needs must be fully adapted. For example, it is necessary to implement multi-dimensional network resource management and coordinated scheduling, that is, it is necessary to uniformly manage and schedule space-based resources and ground-based resources. In addition, based on the time-varying characteristics of the satellite-ground fusion network, it is necessary to consider the autonomous adaptation of network policies, that is, it is necessary to map the service assurance policy to the space-based network and the ground-based network. In addition, the QoS policy needs to be issued by domain, that is, the QoS policy needs to be matched to the space-based and ground-based networks in sections.

[0041] To this end, this application targets the characteristics of the satellite-ground fusion network, such as large spatiotemporal scale, strong topology dynamics, and heterogeneous links. By building a satellite-ground fusion network management system, the quality of network business services is guaranteed, and the satellite-ground fusion joint QoS service quality optimization is achieved for dynamic topology, heterogeneous links, and diversified needs.

[0042] In the present application, the ground communication resources and satellite communication resources in the satellite-ground fusion network can be divided into multiple virtual resource instances, and the resource management module manages the virtual resource pool composed of multiple virtual resource instances. Furthermore, the satellite-ground fusion network management system can realize the convenient scheduling of ground communication resources and satellite communication resources in the satellite-ground fusion network through the interaction between the service quality policy control module, the resource scheduling module, the resource adaptation module and the resource management module, realize the flexible control of the service quality policy in the satellite-ground fusion network, and improve the stability and reliability of the satellite-ground fusion network when providing services. In addition, the present application can support the realization of autonomous adaptation of network policies, map the service quality assurance policy partitions of the business to the ground communication network and the satellite communication network, and fully adapt to the user business needs for the satellite-ground fusion network.

[0043] like Figure 1 , which is a schematic diagram of the structure of a satellite-ground fusion network management system provided in an embodiment of the present application. Figure 1The satellite-ground fusion network management system shown in FIG. 1 includes a resource management module, a service quality policy control module, a resource scheduling module and a resource adaptation module.

[0044] The resource management module is used to manage the status information of the virtual resource pool. The virtual resource pool includes multiple virtual resource instances. The virtual resource instance is used to manage the corresponding allocated ground communication resources and satellite communication resources. The ground communication resources and satellite communication resources managed by a virtual resource instance can form a communication link, supporting user equipment to access the data network via satellite communication resources and ground communication resources in sequence.

[0045] The state information of the virtual resource pool can be used to indicate the running state of each virtual resource instance in the virtual resource pool. The running state of the virtual resource instance can be an idle state or a working state.

[0046] The satellite-ground fusion network consists of multi-dimensional network infrastructure, including the infrastructure resources of mobile communication networks such as the 4th generation mobile communication technology (4G) and the 5th generation mobile communication technology (5G), as well as space-based satellite systems and their supporting ground network resources. The resource management module uses virtualization technology to abstract physical resources based on the multi-dimensional heterogeneous characteristics of heterogeneous network resources to form a unified resource management. Based on this, it can support on-demand virtual resource orchestration for user service requests, no longer restricted by the heterogeneous characteristics of satellite-ground physical resources and capability differences, and resource scheduling is more flexible.

[0047] In one possible manner, the resource management module is further used to divide the multiple ground communication resources and the multiple satellite communication resources into multiple virtual resource instances, and manage the configuration information of each of the multiple virtual resource instances. The configuration information of the virtual resource instance includes ground communication resources, satellite communication resources, allowed service types, etc.

[0048] The service quality policy control module is used to determine the target service quality policy that matches the service to be guaranteed.

[0049] Optionally, the service quality policy control module can be specifically used to identify the target service type of the service to be guaranteed, and determine the preset service quality policy corresponding to the target service type from multiple preset service quality policies as the target service quality policy. Different preset service quality policies correspond to different preset service types. Multiple preset service types may include low latency type, user intensive type or large data volume transmission type, etc. The target service type may be any one of multiple preset service types.

[0050] Alternatively, the service quality policy control module may be specifically used to identify the network resources currently used by the service to be guaranteed, and determine whether the network resources currently used by the service to be guaranteed match the current traffic volume of the service to be guaranteed. Furthermore, the service quality policy control module may determine that the target service quality policy that matches the service to be guaranteed is to adjust the network resources currently used by the service to be guaranteed to network resources with a larger bandwidth when the network resources currently used by the service to be guaranteed cannot match the current traffic volume of the service to be guaranteed.

[0051] Furthermore, the service quality policy control module is also used to obtain the status information of the virtual resource pool from the resource management module, and send the target service quality policy and the status information of the virtual resource pool to the resource scheduling module. Correspondingly, the resource scheduling module is also used to receive the target service quality policy and status information from the service quality policy control module. In this way, the service quality policy control module can realize the generation and distribution of QoS policies in the satellite-ground fusion network.

[0052] The resource scheduling module is used to determine the target virtual resource instance for the guaranteed service allocation from multiple virtual resource instances according to the target service quality policy and the status information of the virtual resource pool. Specifically, the resource scheduling module can determine the virtual resource instance in the virtual resource pool that is in an idle state and meets the target service quality policy as the target virtual resource instance.

[0053] In actual application, the resource scheduling module can issue resource scheduling control strategies and QoS requirements to the satellite communication resource control system and the ground communication resource control system through the southbound interface to achieve global control of the satellite-ground fusion network. The satellite communication resource control system and the ground communication resource control system mainly implement the control strategies and QoS requirements issued by the main control system, generate the optimal control strategy within the domain in combination with the network situation within the domain, and issue it to the network elements within the domain through the southbound interface. End-to-end automated network configuration is achieved through a multi-level management controller, and the resource scheduling actions given by the resource scheduler are quickly executed to achieve real-time on-demand scheduling of end-to-end resources for multiple users, multiple services, multiple accesses, multiple subnets, and multiple protocols. Based on this, the present application can generate a global optimal resource scheduling strategy based on the global situation of the satellite-ground fusion network and the corresponding business needs, and achieve on-demand scheduling of end-to-end transmission resources.

[0054] Furthermore, the resource scheduling module may send adaptation indication information to the resource adaptation module. The adaptation indication information is used to indicate the configuration of the target virtual resource instance for the service to be guaranteed. Accordingly, the resource adaptation module may receive the adaptation indication information from the resource scheduling module.

[0055] The resource adaptation module is used to establish a network link corresponding to the service to be guaranteed based on the target virtual resource instance.

[0056] The resource adaptation module has the function of adaptive intelligent adaptation of network resources, which can realize the adaptive adaptation of virtual instance resource scheduling strategies and physical network elements, so that each network node executes the resource scheduling strategy and realizes the data transmission of the task to be guaranteed. In view of the time-varying network topology and link conditions on the resource supply side, the intelligent adaptive scheduling strategy is adaptively and dynamically adjusted according to the time-varying situation of resources to allocate resources on demand, and at the same time, the mapping and matching between virtual pooled resources and physical network elements and the on-demand adjustment of resources are realized. Centralized scheduling of cross-layer domain transmission resources for multiple users, multiple services, multiple accesses, multiple subnets, and multiple protocols is realized to realize the coordinated scheduling of layer domain transmission resources to meet the differentiated service performance requirements and transmission resource capacity constraints.

[0057] For example, Figure 2 As shown, it is a schematic diagram of the structure of a satellite-ground fusion network provided in an embodiment of the present application. The infrastructure resources of mobile communication networks such as 4G and 5G may include the facility resources of access network, bearer network and core network. The space-based satellite system may include a low-orbit satellite equipped with base station equipment and ground control equipment supporting it. The low-orbit satellite accesses the bearer network of mobile communication networks such as 4G and 5G through the ground control equipment.

[0058] When the user equipment is not connected to the low-orbit satellite, the services of the user equipment can be guaranteed by the interaction between network elements such as mobile management, session management, user plane functions, and user data plane in the core network of mobile communication networks such as 4G and 5G, thereby achieving service quality assurance and accessing the data network with high reliability and low latency.

[0059] When the user equipment accesses a low-orbit satellite, the services of the user equipment can be guaranteed by the interaction between the packet resource management module, service quality policy control module, resource scheduling module and resource adaptation module in the satellite-ground integrated network management system located in the network layer, so as to access the data network with high reliability and low latency.

[0060] First, the main controller performs global QoS decomposition and extracts hierarchical and domain-based task QoS based on the input differentiated services and sends them to each distributed controller, forming a closed-loop decomposition of service demand-global QoS-task QoS; second, each distributed controller matches its task QoS with the pooled resources in its domain on demand, generates the optimal resource scheduling strategy in the domain, and performs a closed-loop allocation of task QoS-pooled resources; finally, the resource scheduling strategy is adaptively adapted to the physical network elements, and each network node executes the resource scheduling strategy to realize task transmission.

[0061] In one possible manner, the resource adaptation module is further used to send a policy execution result to the resource management module. The policy execution result is used to indicate the correspondence between the target service quality policy and the target virtual resource instance. Accordingly, the resource management module can receive the policy execution result from the resource adaptation module and update the state of the target virtual resource instance. That is, the resource management module can update the state of the target virtual resource instance from an idle state to a working state.

[0062] In one possible manner, the resource management module is further used to send a service assurance prompt to the user equipment corresponding to the service to be guaranteed through the service quality policy control module. The service assurance prompt is used to prompt the successful execution of the service quality policy corresponding to the service to be guaranteed. In this way, the user can intuitively understand the service quality assurance of the satellite-ground integrated network for the service, thereby improving the user experience.

[0063] like Figure 3 The figure is a schematic diagram of a service assurance process provided in an embodiment of the present application. Figure 3 The service assurance process shown includes: S1-S6.

[0064] S1. User equipment sends a service assurance request to a service quality policy control module.

[0065] S2. The service quality policy control module queries the status information from the resource management module, and sends the target service quality policy and the status information of the virtual resource pool to the resource scheduling module.

[0066] The service quality policy control module can obtain the status information of the virtual resource pool from the resource management module, and determine the target service quality policy that matches the service to be guaranteed. Furthermore, the service quality policy control module can send the target service quality policy and the status information of the virtual resource pool to the resource scheduling module. Correspondingly, the resource scheduling module can receive the target service quality policy and the status information of the virtual resource pool from the service quality policy control module, and determine the target virtual resource instance allocated to the service to be guaranteed from multiple virtual resource instances according to the target service quality policy and the status information of the virtual resource pool, so as to generate adaptation indication information.

[0067] S3. The resource scheduling module sends adaptation indication information to the resource adaptation module.

[0068] S4. The resource adaptation module sends the policy execution result to the resource management module.

[0069] S5. The resource management module sends a service assurance prompt to the service quality policy control module.

[0070] S6. The service quality policy control module sends a service assurance prompt to the user equipment.

[0071] Optionally, the resource management module, service quality policy control module, resource scheduling module and resource adaptation module in the satellite-ground integrated network management system can be deployed on the same network device or on different network devices respectively. This embodiment of the application does not limit this.

[0072] like Figure 4 , which is a schematic diagram of the hardware structure of a network device provided in an embodiment of the present application. The network device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected via a bus 24.

[0073] The processor 21 is the control center of the network device, which can be a processor or a general term for multiple processing elements. For example, the processor 21 can be a CPU or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

[0074] As an embodiment, the processor 21 may include one or more CPUs, such as Figure 4 CPU0 and CPU1 are shown in the figure.

[0076] In a possible implementation, the memory 22 may exist independently of the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 to store instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the satellite-ground fusion network management method provided in the following embodiments of the present application can be implemented.

[0077] In another possible implementation, the memory 22 may also be integrated with the processor 21 .

[0078] The communication interface 23 is used for the network device to connect with other devices through a communication network, and the communication network may be Ethernet, wireless access network, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

[0079] The bus 24 may be an industrial standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industrial standard architecture (EISA) bus. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 4 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0080] It should be pointed out that Figure 4 The structure shown in the figure does not constitute a limitation on the network equipment, except Figure 4 In addition to the components shown, the network device may include more or fewer components than shown, or combine certain components, or arrange the components differently.

[0081] like Figure 5 FIG. 1 is a flow chart of a satellite-ground fusion network management method provided in an embodiment of the present application. The satellite-ground fusion network management method can be applied to Figure 1 The satellite-ground integrated network management system shown, or Figure 4 The network device shown is deployed with a satellite-ground integrated network management system. The satellite-ground integrated network management method includes: S501-S504.

[0082] S501. The satellite-ground integrated network management system responds to a service assurance request and identifies a target service type of a service to be assured.

[0083] The service assurance request is used to request the assurance of the service quality of the service to be assured.

[0084] Optionally, the target service type may be any one of a low-latency type, a user-intensive type, a large data volume transmission type, and the like.

[0085] S502. The satellite-ground integrated network management system determines a preset service quality policy corresponding to a target service type from a plurality of preset service quality policies as a target service quality policy matching the service to be guaranteed.

[0086] Among them, different preset service quality strategies correspond to different preset service types.

[0087] S503: The satellite-ground integrated network management system determines a target virtual resource instance to be allocated to the service to be guaranteed from multiple virtual resources according to the target service quality policy and the status information of the virtual resource pool.

[0089] S504. The satellite-ground integrated network management system establishes a network link corresponding to the service to be guaranteed based on the target virtual resource instance.

[0090] The satellite-ground integrated network management system can configure network links based on the ground communication resources and satellite communication resources corresponding to the target virtual resource instance, and activate the network links after the configuration is completed, so that user equipment can transmit data of the service to be guaranteed through the network link.

[0091] It should be understood that regarding the implementation of the above S501-S504, reference may be made to the above-mentioned detailed description of the interaction between the various modules in the satellite-ground integrated network management system, which will not be repeated here.

Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0093] The embodiment of the present application can divide the functional modules of the network device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
