[0055] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] Figure 1 Schematic diagram of the composition structure of the communication system according to an embodiment of the present invention; as Figure 1 shown, the communication system of this embodiment may include: a terminal, a core network deployed on the ground (referred to as Figure 1 the ground core network in), a gateway device, and a spaceborne device; wherein,

[0057] The terminal is used to attempt to access the core network deployed on the ground. When it is determined that the access to the core network deployed on the ground cannot be achieved within a preset condition, it searches for a spaceborne device that provides a spaceborne communication network and sends network access information to the spaceborne device;

[0058] The gateway device is used to send network element failure information to the spaceborne device when it detects a failure of the core network deployed on the ground. The network element failure information represents the failure information of the core network elements deployed on the ground;

[0059] The spaceborne device is used to deploy corresponding network elements according to the network element failure information; and is also used to complete the network access of the terminal according to the network access information.

[0060] In this embodiment, some core network element functions are deployed in the spaceborne device. Optionally, access network element functions may also be deployed in the spaceborne device. Exemplarily, base station (gNB) functions in a 5G network and some core network element functions may be deployed in the spaceborne device, thus forming a coexisting, complementary, and collaborative relationship with the mobile network deployed on the ground. For communication area scenarios where it is impossible to deploy a ground core network or the ground core network cannot meet user requirements (such as deserts, ecological protection areas, offshore operations, air military, etc.), a reliable mobile network can be provided by the spaceborne device.

[0061] The mobile network in this embodiment, which can also be referred to as a communication system, is applicable to various mobile networks or communication systems, such as Global System of Mobile communication (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), or 5G system, etc.

[0062] The spaceborne device in this embodiment is located on a communication satellite. Exemplarily, the communication satellite can be a low-earth orbit communication satellite, which generally refers to a satellite system composed of multiple satellites that can perform real-time information processing. The low orbit altitude of the low-earth orbit communication satellite results in short transmission delay and small path loss, and a system composed of multiple satellites achieves global coverage.

[0063] In this embodiment, the spaceborne device deploys AMF, SMF, and UPF; optionally, a Data Network (DN) can also be deployed in the spaceborne device.

[0064] In this embodiment, the network element fault information at least includes at least one of the following: network element information, fault information, and local data configuration information; the spaceborne device specifically performs resource scheduling according to the fault information, completes the instantiation of the network element corresponding to the network element information, and performs configuration according to the local data configuration information.

[0065] In this embodiment, a gateway device is deployed on the ground, which is responsible for information interaction between the core network deployed on the ground and the spaceborne core network deployed in the spaceborne device, such as protocol conversion, signaling and data transmission; consider the follow-up. Exemplarily, the deployment location of the gateway device is close to the satellite gateway of the low-earth orbit satellite, which is beneficial to the subsequent transmission of network element fault information.

[0066] Based on the above communication system, an embodiment of the present invention provides an information processing method for network access. Figure 2 Flow schematic of the information processing method for network access according to the embodiment of the present inventionFigure 1 ; As Figure 2 shown, the method includes:

[0067] Step 101: The spaceborne device receives the network element fault information sent by the gateway device; the network element fault information characterizes the fault information of the core network element deployed on the ground;

[0068] Step 102: The spaceborne device deploys the corresponding network element according to the network element fault information.

[0069] In this embodiment, after the gateway device detects the fault of the core network element deployed on the ground, it obtains the network element fault information and can send the network element fault information to each spaceborne device through the link between the spaceborne device and the ground core network as Figure 1 shown. That is, each spaceborne device can receive the network element fault information sent by the gateway device.

[0070] In some optional embodiments of the present invention, the network element fault information includes at least one of the following: network element information, fault information, and local data configuration information; the spaceborne device deploys the corresponding network element according to the network element fault information, including: the spaceborne device performs resource scheduling according to the fault information, completes the instantiation of the network element corresponding to the network element information, and configures according to the local data configuration information.

[0071] In this embodiment, each spaceborne device can, according to the fault situation of the core network deployed on the ground, for example, the category of the faulty network element, instantiate the corresponding network element according to the network element category, and configure the network element according to the local data configuration information, so as to achieve the rapid deployment of the disaster recovery network element and the rapid import of the configuration file.

[0072] Exemplarily, an intelligent orchestration module can be set in each spaceborne device, and the intelligent orchestration module is responsible for the management of the spaceborne core network, the management of spaceborne resources, scheduling, orchestration, the rapid deployment of disaster recovery network elements, and the rapid import of configuration files, etc.

[0073] In this embodiment, the spaceborne device includes an AMF, an SMF, and a UPF; any two network functions between the AMF, the SMF, and the UPF interact through an internal interface. In some embodiments, the spaceborne device further includes a data network, and any two network elements between the AMF, the SMF, the UPF, and the data network interact through an internal interface. There is no need for a service-based call mechanism inside the spaceborne device, that is, there is no need for a call mechanism under the service-based architecture (SBA, Service-based Architecture).

[0074] In this embodiment, the spaceborne device has a service-based interface function for interacting with the core network deployed on the ground based on SBA.

[0075] In some alternative embodiments, the AMF and SMF in the spaceborne device have the same configuration as the AMF and SMF in other spaceborne devices in the same galaxy; the AMF and SMF in the spaceborne device and the AMF and SMF in other spaceborne devices in different satellite orbits are in a load sharing mode.

[0076] In this embodiment, the spaceborne devices in the same galaxy may refer to the devices deployed on multiple satellites capable of achieving global coverage. Exemplarily, each spaceborne device described in this embodiment may be considered as a spaceborne device in the same galaxy, and the spaceborne devices in the same galaxy may move along different satellite orbits. Referring to Figure 1 As shown, the configurations of the AMF and SMF deployed in the spaceborne devices located in satellite orbit 1 and satellite orbit 2 respectively are the same. The AMF and SMF in each spaceborne device are in a load sharing mode.

[0077] Among them, the configurations of the AMF and SMF may specifically be the local data configurations of the corresponding network functions.

[0078] Exemplarily, each spaceborne device may complete the access restriction of the terminal based on the configurations of the AMF and SMF, according to its own capabilities and resource usage conditions, so that the services of the terminal can be allocated to the spaceborne devices within each communication range.

[0079] In some alternative embodiments, the UPF in the spaceborne device has the same configuration as the UPF in other spaceborne devices in the same satellite orbit, and the UPF in the spaceborne device has a different configuration from the UPF in other spaceborne devices in different satellite orbits; the UPF in the spaceborne device and the UPF in other spaceborne devices in different satellite orbits are in a convergence and diversion mode.

[0080] In this embodiment, considering the diversion ability of the UPF, the configurations of the UPFs of the spaceborne devices in the same satellite orbit are the same, and the configurations of the UPFs of the spaceborne devices in different satellite orbits are different. Referring to Figure 1 As shown, the configurations of the UPFs deployed in the spaceborne devices in satellite orbit 1 are the same (all denoted as UPF1), and the configurations of the UPFs deployed in the spaceborne devices in satellite orbit 2 are the same (all denoted as UPF2), that is, the configurations of the UPFs deployed in the spaceborne devices in different satellite orbits are different. In this embodiment, the UPFs of the spaceborne devices in different satellite orbits are in a convergence and diversion mode. Among them, the configuration of the UPF may specifically be the local data configuration.

[0081] In this embodiment, data is transmitted between the spaceborne device and other spaceborne devices through an inter-satellite link. That is, the transmission of UPF data between different spaceborne devices is realized through the inter-satellite link.

[0082] In some alternative embodiments of the present invention, the method further includes: the spaceborne device receives the network access information of the terminal and completes the network access of the terminal according to the network access information.

[0083] Optionally, the spaceborne device can complete the restriction of user access according to the configuration information such as the priority and / or QoS corresponding to the terminal. Since the capacity of the spaceborne device is limited, this method can preferentially guarantee the access and services of users with high priority and / or high QoS requirements, such as medical security during disasters, etc.

[0084] Based on the above embodiments, the embodiments of the present invention further provide an information processing method for network access. Figure 3 The flow diagram of the information processing method for network access according to the embodiments of the present invention Figure 2 ; As Figure 3 shown, the method includes:

[0085] Step 201: The terminal attempts to access the core network deployed on the ground. When it is determined that the access to the core network deployed on the ground cannot be achieved within a preset condition, it searches for a spaceborne device for providing a spaceborne communication network;

[0086] Step 202: The terminal sends network access information to the spaceborne device.

[0087] In some alternative embodiments of the present invention, the determination that the access to the core network deployed on the ground cannot be achieved within a preset condition includes: when the terminal attempts to access the core network deployed on the ground, it enables a timer; within the timing range of the timer, when the terminal does not receive a signal indicating access to the core network deployed on the ground, it is determined that the access to the core network deployed on the ground cannot be achieved within a preset condition.

[0088] In this embodiment, the terminal can be provided with a timer; when the terminal initiates access to the core network deployed on the ground, the timer is started, and the timing duration of the timer can be set based on the general duration for the terminal to complete network access. Within the timing range of the timer, or when the timer times out, if the terminal still does not receive a signal indicating access to the core network deployed on the ground, it can be determined that the terminal cannot access the core network deployed on the ground within a preset condition; further, the terminal starts to search for a spaceborne device for providing a spaceborne communication network and sends network access information to the spaceborne device.

[0089] Based on the above embodiments, the embodiments of the present invention further provide an information processing method for network access. The method can refer to Figure 4Schematic diagram of the application scenario. The method includes: the terminal attempts to access the core network deployed on the ground, and when it determines that it cannot access the core network deployed on the ground within the preset conditions, it searches for a spaceborne device for providing a spaceborne communication network and sends network access information to the spaceborne device; when the gateway device detects a failure of the core network deployed on the ground, it sends network element failure information to the spaceborne device, and the network element failure information represents the failure information of the core network elements deployed on the ground; the spaceborne device deploys the corresponding network elements according to the network element failure information and completes the network access of the terminal according to the network access information.

[0090] In this embodiment, exemplarily, an access network device (base station), AMF, SMF, UPF, data network, and intelligent orchestration module may be deployed in the spaceborne device, that is, an access network function and some core network functions such as AMF, SMF, UPF, and data network are deployed in the spaceborne device, and a spaceborne communication network is implemented through the above functions to provide communication services for the terminal.

[0091] In this embodiment, the intelligent orchestration module is responsible for the management of the spaceborne core network, the management of spaceborne resources, scheduling, orchestration, rapid deployment of disaster recovery network elements, and rapid import of configuration files, etc. Exemplarily, the intelligent orchestration module can receive the network element failure information sent by the gateway device, perform resource scheduling according to the failure information in the network element failure information, complete the instantiation of the network elements corresponding to the network element information, and configure according to the local data configuration information, so as to realize the rapid deployment of disaster recovery network elements and the rapid import of configuration files, etc.

[0092] Adopting the technical solution of the embodiment of the present invention, on the one hand, according to the operating characteristics and inter-satellite interaction characteristics of low-earth orbit satellites, AMF, SMF, UPF (and may also include a data network) are deployed on the satellite, and a centralized deployment principle is adopted, which can provide a reference for the future networking architecture of the spaceborne core network. On the other hand, it realizes the complementary form and service continuity between the spaceborne core network and the ground core network. In the case of a ground core network failure, the gateway device deployed on the ground sends network element failure information to the spaceborne device, so that the spaceborne device deploys the corresponding network elements, thereby realizing the rapid integration of spaceborne resources and the rapid deployment of disaster recovery network elements by the spaceborne device, thus improving the utilization rate of spaceborne resources. On the other hand, it also provides ideas for the integrated networking of satellite networks and ground mobile communication networks.
