Description

Technical Field

[0001] This invention relates to the field of mobile communication network technology, and in particular to a network element status management method, apparatus, electronic device, and storage medium. Background Technology

[0002] With technological advancements, mobile networks have successfully served billions of users. Deploying mobile networks to satellites has alleviated operational cost issues.

[0003] As is known from relevant technologies, current mobile networks are highly stateful. To provide carrier-grade services, mobile networks need to establish sessions between user equipment (UEs) and the network infrastructure. As UEs move, the mobile core network migrates the state of the network infrastructure to the new infrastructure nodes, thereby providing continuous service to UEs. These state operations must succeed before data services can be provided; otherwise, data services will be blocked.

[0004] However, the high frequency of state transitions between highly mobile satellites can cause significant problems even when user equipment remains stationary. This can lead to signaling storms in the satellite network, exhausting satellite hardware, congesting ground stations, and delaying user service. Summary of the Invention

[0007] According to a network element status management method provided by the present invention, the step of determining the mobile network location status of the satellite network to be processed based on the geographic location area specifically includes: determining the target geographic location based on the geographic location area; taking the target geographic location embedded in the user equipment IP address as the target location status of the user equipment corresponding to the user equipment IP address; and determining the mobile network location status of the satellite network to be processed based on the target location status.

[0008] According to a network element state management method provided by the present invention, after determining the mobile network location state of the satellite network to be processed based on the target location state, the network element state management method further includes: determining the logical location state of the block number corresponding to the service area in the satellite network to be processed, and the state transmission process corresponding to the logical location state; deleting the logical location state and the state transmission process from the mobile network location state, and taking the mobile network location state after deleting the logical location state and the state transmission process as the final mobile network location state.

[0009] According to a network element state management method provided by the present invention, the step of entrusting other states of the satellite network to be processed to local user equipment to obtain a distributed local state library specifically includes: creating a local state memory in each of the local user equipments; tracking and storing other states of the satellite network to be processed based on the local state memory; and obtaining the distributed local state library based on the local state memory storing the other states.

[0010] According to a network element state management method provided by the present invention, after obtaining the distributed local state library based on the local state memory storing the other states, the network element state management method further includes: when the satellite needs the other states during the process of serving the user equipment, and when the satellite obtains authorization to access the distributed local state library, obtaining the other states from the local state memory of the local user equipment.

[0011] According to a network element state management method provided by the present invention, the satellite obtains the other states in the following manner: during the establishment of a session control connection, the other states are embedded into the establishment success message of the session control connection through associated signaling; based on the received establishment success message, the other states are obtained from the establishment success message.

[0012] According to a network element state management method provided by the present invention, after the other states of the satellite network to be processed are entrusted to local user equipment to obtain a distributed local state database, the network element state management method further includes: encrypting each of the distributed local state databases with a public key and using attribute-based encryption controlled by the home network, allowing the home network to formulate access control policies to resist unauthorized access or modification of the state by other user equipment and / or other satellites, wherein the access control policies are determined according to the user equipment and the satellite.

[0013] According to a network element state management method provided by the present invention, the state management process includes a localized uplink session establishment process, a localized downlink session establishment process, and a state management process during mobility registration.

The process includes establishing a session and removing fixed anchor gateways from the satellite network to be processed, as well as performing stateless data forwarding between satellites using the user equipment IP address including the target geographical location. Based on the distributed local state database and the target location state, the mobility registration state management process is constructed and run. This process is used to eliminate re-registration caused by satellite dynamics, and when the user equipment switches from the satellite to another satellite, it carries a copy of the distributed local state database in the switchover confirmation information to the other satellite to achieve state migration.

[0014] According to a network element state management method provided by the present invention, after constructing and running the localized uplink session establishment process based on the distributed local state database, the network element state management method further includes: when the home network authorizes the satellite to access the target state, decrypting the encrypted state of the distributed local state database based on the public key to obtain data information corresponding to the state; when the home network does not authorize the satellite to access the target state, rolling back to a pre-set standard procedure based on the home network.

[0015] According to a network element state management method provided by the present invention, the step of obtaining a stateless terrestrial-satellite integrated mobile network corresponding to the satellite network to be processed based on the mobile network location state, the distributed local state database, and the state management process specifically includes: replacing the home network of the satellite network to be processed with a target home network based on the mobile network location state, the distributed local state database, and the state management process; using the target home network as the common home network of the terrestrial network and the satellite; and obtaining a stateless terrestrial-satellite integrated mobile network corresponding to the satellite network to be processed based on the common home network of the terrestrial network and the satellite.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this 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 this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0036] According to relevant technologies, deploying mobile core networks on satellites presents problems. Unlike fixed terrestrial infrastructure, LEO satellites move rapidly in the unreliable and untrusted outer space globally. Placing the mobile core network on LEO satellites would expose it to signaling storms, duplicate mobile registrations by a large number of static users, service interruptions due to satellite malfunctions, and the leakage of sensitive state (such as security keys) due to satellite attacks. These problems become more severe as each satellite serves an increasing number of satellites and users.

[0037] The root cause of these problems lies in the stateful mobile core network. To provide carrier-grade services, the mobile network needs to establish sessions between User Equipment (UE) and infrastructure with states related to traffic delivery, mobility, QoS, billing, and security. As UEs move, the core network migrates these states to new infrastructure nodes to maintain continuous service. These state operations must succeed before data services can be provided; otherwise, data services will be blocked. While feasible for fixed terrestrial infrastructure, this design results in a significant amount of static UE state being migrated between satellites. Furthermore, these states are vulnerable to satellite failures, which are not uncommon in the harsh space environment. In addition, the stateful satellite core network is inevitably exposed to locations in other countries, making it susceptible to attacks and the leakage of sensitive state (such as security keys).

[0038] To address the aforementioned issues, this invention proposes a network element state management mechanism (corresponding to a network element state management method) for a space-ground integrated mobile network. Based on a geolocation-based state management mechanism, it decouples state from core network functions, simplifies state positioning through geolocation addressing, and reduces state migration between satellites by using geolocation service areas and user equipment as a local state repository, thereby improving network performance and scalability. Furthermore, it supports state control by the home network, ensuring state security as malicious users and satellites cannot tamper with the state.

[0039] Figure 1This is one of the flowcharts of the network element status management method provided by the present invention.

[0040] To further introduce the network element status management method provided by this invention, the following will be combined with... Figure 1 Please provide an explanation.

[0041] In an exemplary embodiment of the present invention, combined with Figure 1 As can be seen, the network element status management method may include steps 110 to 150, and each step will be described below.

[0042] In step 110, the service area in the satellite network to be processed is decoupled from the preset satellites, and the service area is defined as a geographic location region, which is a region obtained by dividing the area into blocks based on geographic location. The service area in the satellite network to be processed is coupled to the preset satellites. The satellite network to be processed is a network constructed from satellites and ground networks, and the service area includes base station cells and tracking areas.

[0043] In one embodiment, the satellite network to be processed can be understood as a traditional satellite network. In this traditional satellite network, the logical service area (including the tracking area and base station cells) is bound to low-Earth orbit satellites, i.e., coupled to preset satellites. The preset satellites can be determined based on actual circumstances and are not specifically limited in this embodiment.

[0044] In one embodiment, continuing with the previously described embodiments, the logical service area in traditional satellite network design can be decoupled from the low-Earth orbit satellites, and a geographic location service area (corresponding to a geographic location region) can be adopted instead, so that the geographic location service area remains stable under the high dynamics of satellites. In application, the original logical area identifiers, such as block IDs and tracking area IDs, can be discarded, and block partitioning can be used to track the location of user equipment.

[0045] In another embodiment, the geographic location region is a region obtained by dividing it into blocks based on geographic location. In one example, multiple geographic location block division methods can be supported, including but not limited to those based on latitude and longitude, Google S2, Uber H3, and satellite orbit parameters.

[0046] In another example, the blocks need to meet the following conditions: full coverage of the Earth's surface or full coverage of the operator's planned service area; and no overlap between blocks, meaning that a user device can only have one block number at a time.

[0047] In another embodiment, during the block division process, the Earth can be projected onto the plane first, as in S2 and H3, and then the plane can be filled with the same shapes, such as the square in S2 and the regular hexagon in H3; or the Earth's sphere can be directly divided into non-overlapping blocks according to latitude and longitude blocks or by providing orbital parameters.

[0048] In step 120, the mobile network location status of the satellite network to be processed is determined based on the geographic location area.

[0049] In one embodiment, the mobile network location status of the satellite network to be processed can be determined based on the geographic location area, thereby simplifying the mobile network location status and eliminating unnecessary state management and migration.

[0050] Figure 2 This is a flowchart illustrating the process of determining the location status of a mobile network of a satellite network to be processed based on a geographic location area, as provided by the present invention.

[0051] To further explain the process of determining the mobile network location status of a satellite network to be processed based on geographic location area, the following will combine... Figure 2 Please provide an explanation.

[0052] In an exemplary embodiment of the present invention, combined with Figure 2 As can be seen, determining the mobile network location status of the satellite network to be processed based on the geographical location area may include steps 210 to 230, which will be described in detail below.

[0053] In step 210, the target geographic location is determined based on the geographic location area.

[0054] In step 220, the target geographical location embedded in the user equipment IP address is used as the target location status of the user equipment corresponding to the user equipment IP address.

[0055] In step 230, the mobile network location status of the satellite network to be processed is determined based on the target location status.

[0056] In one embodiment, the target geographical location of the user equipment (UAE) can be determined based on a geographic region. The geographical location (corresponding to the target geographical location) is then embedded in the UAE's IP address as the UAE's location status. During application, the satellite directly obtains the UAE's location status from its IP address. In another example, when the satellite needs the UAE's location status, such as during session establishment or inter-satellite handover, the satellite can directly read the UAE's location status from its IP address, thereby reducing signaling transmission.

[0057] In another embodiment, the user equipment IP address can be improved. Geographic location-based addressing embeds the geographic location into the user equipment IP address.

[0058] Figure 5 This is a schematic diagram of the structure of the user equipment IP address provided by the present invention.

[0059] Combination Figure 5 As can be seen, the user equipment IP address contains the carrier ID, the geographical location of the home network, the geographical location of the user's current block, and a unique identifier within the block. It should be noted that for the user equipment IP address in this invention, it is sufficient to embed the geographical location information into the IP address.

[0060] To further illustrate the network element status management method provided by this invention, the following embodiments will be used for explanation.

[0061] In an exemplary embodiment of the present invention, continuing with Figure 2 Taking the above embodiment as an example, after determining the mobile network location status of the satellite network to be processed based on the target location status (corresponding to step 230), the network element status management method may further include the following steps:

[0062] Determine the logical location status of the block number corresponding to the service area in the satellite network to be processed, and the status transfer process corresponding to the logical location status;

[0063] The logical location state and state transit process are deleted from the mobile network location state, and the mobile network location state after deleting the logical location state and state transit process is taken as the final mobile network location state.

[0064] In one embodiment, logical location states such as block numbers and related state transfer processes can be removed from the mobile network location state. In one example, the block ID and tracking area ID states in the mobile network can be removed. The corresponding state transition process is then modified so that the geographic location state is no longer explicitly transferred during session establishment and mobility registration. This embodiment simplifies unnecessary network element states and reduces state transition signaling costs.

[0065] In step 130, the other states of the satellite network to be processed are managed by the local user equipment to obtain a distributed local state library. The other states are those in the satellite network to be processed, excluding the mobile network location state. The resulting distributed local state library is... Figure 6 A distributed state repository in the system.

[0066] In one embodiment, other states of the satellite core network can be delegated to local user equipment, thereby forming a distributed geospatial local state database. During application, any authorized stateless satellite entering the service area can use the local states in the distributed local state database to serve user equipment, which can effectively reduce the number of signaling migrations and avoid signaling storms.

[0067] In step 140, the state management process for the key signaling of the satellite network to be processed is run based on the distributed local state library.

[0068] In one embodiment, the state management process for critical signaling of the satellite network to be processed can be determined based on a distributed local state library. In this embodiment, utilizing the local states in the distributed local state library can simplify the state management process for core critical signaling of traditional mobile networks, thereby improving network performance and scalability during the process.

[0069] In step 150, based on the mobile network location status, the distributed local state database, and the state management process, a stateless terrestrial-satellite integrated mobile network corresponding to the satellite network to be processed is obtained. This stateless terrestrial-satellite integrated mobile network is a network composed of satellite and terrestrial networks that has not undergone state transition. Figure 6 and Figure 7 These are a simplified structural diagram and a detailed structural diagram of the stateless space-ground integrated mobile network provided by the present invention.

[0070] In one embodiment, a stateless terrestrial-satellite integrated mobile network corresponding to the satellite network to be processed can be obtained based on the mobile network location status, a distributed local state database, and a state management process, thereby achieving seamless integration of satellite and traditional terrestrial 5G mobile networks. It should be noted that the stateless terrestrial-satellite integrated mobile network is a network composed of satellite and terrestrial networks without state migration. This embodiment realizes a stateless terrestrial-satellite integrated mobile core network, thereby improving mobile network performance and avoiding signaling storms.

[0071] The network element state management method provided by this invention effectively reduces state migration by decoupling the service area in the satellite network to be processed from the preset satellites and defining the service area as a geographical location region. Furthermore, by entrusting other states of the satellite network to be processed to local user equipment to obtain a distributed local state database, and then based on the mobile network location state, the distributed local state database, and the state management process, a stateless terrestrial-space integrated mobile network corresponding to the satellite network to be processed can be obtained. This achieves a stateless terrestrial-space integrated mobile core network, thereby improving mobile network performance and avoiding signaling storms.

[0072] To further illustrate the process of transferring other states of the satellite network to be processed to local user equipment to obtain a distributed local state database, the following embodiments will be used as examples.

[0073] In an exemplary embodiment of the present invention, entrusting other states of the satellite network to be processed to a local user equipment to obtain a distributed local state database may include the following steps:

[0074] A local state memory is created on each local user equipment, and other states of the satellite network to be processed are tracked and stored based on the local state memory.

[0075] A distributed local state library is obtained by storing other states in the local state memory.

[0076] In one embodiment, a system application can be created within the commodity user equipment to run a local state agent, i.e., a distributed local state library is obtained through a local state storage created on the local user equipment. During application processing, the agent stores the user equipment state from the home network during initial registration. In subsequent signaling processes, this repository updates the state as needed.

[0077] To further illustrate the process provided by this invention of entrusting other states of a satellite network to be processed to a local user device to obtain a distributed local state database, the following description will be provided in conjunction with the embodiments below.

[0078] In yet another exemplary embodiment of the present invention, continuing with the previously described embodiments, after obtaining a distributed local state library based on a local state memory storing other states, the network element state management method may further include the following steps:

[0079] Other states are required during the satellite service user equipment process, and other states are retrieved from the local state storage of the local user equipment when the satellite is authorized to access the distributed local state library.

[0080] In one embodiment, when a satellite needs the state of a user it serves, it can retrieve the user's state (corresponding to other states) from the local state memory of the local user equipment, if authorized, to reduce state migration between the satellite and the home network.

[0081] Taking handover as an example, when a user switches satellites, the new satellite obtains the encrypted status of the user's equipment from the handover confirmation message returned by the user's equipment. If the satellite is authorized to read this status, it runs a decryption program to decrypt the status. Furthermore, the satellite can use this status to provide data services to the user.

[0082] In yet another exemplary embodiment of the present invention, continuing with the previously described embodiments, the satellite can obtain other states in the following manner:

[0083] During the establishment of a session control connection, other states are embedded into the session control establishment success message through accompanying signaling.

[0084] Based on the received successful establishment message, other statuses are obtained from the successful establishment message.

[0085] In one embodiment, a mechanism based on in-band signaling transmission status can be used concurrently with signaling interaction. Specifically, while the session control connection is established, the user's status is embedded in its Radio Resource Control (RRC) establishment success signaling message via in-band signaling. When the satellite receives the RRC establishment success message, it can directly read the user's status (corresponding to other statuses) from the message.

[0086] To further illustrate the network element status management method provided by this invention, the following embodiments will be used for explanation.

[0087] In an exemplary embodiment of the present invention, the following combination continues... Figure 1 The above embodiment is used as an example for illustration. After entrusting other states of the satellite network to be processed to the local user equipment to obtain a distributed local state database (corresponding to step 130), the network element state management method may further include the following steps:

[0088] Public keys are used to encrypt and protect each distributed local state database, and attribute-based encryption controlled by the home network is used to allow the home network to formulate access control policies to prevent unauthorized access or modification of state by other user equipment and / or other satellites. The access control policies are determined based on the user equipment and satellite.

[0089] In one embodiment, only the home network has permission to modify and update other states (excluding geographic location states). Public-key cryptography is used to provide local security and state protection for each distributed local state database, and attribute-based encryption controlled by the home network allows the home network to specify access control policies based on device and satellite attributes. This protects against unauthorized access to or modification of device / satellite states, improving the security of other states placed on user devices.

[0090] In another embodiment, the home network can receive dynamic data usage reports from remote satellites, and the core network control plane of the home network (such as...) Figure 6(As shown) it runs its policy control functions and uses a session modifier to update session state to the local user equipment and the satellite serving the local user equipment. In one example, the home network stores the QoS and billing information of the user equipment and receives data usage reports from the user equipment and satellite transmissions. In one example, this can be stored in... Figure 7 In the PCF (Platform Controller Function), when a change to the tower status is required (e.g., when data usage exceeds a certain limit and the rate cap needs to be changed), the home network sends a status update command to the user equipment and the served satellite. After the user equipment and the served satellite authenticate the status update command as from the home network, they run the status update program to update the current status and the status of the user equipment's status memory (corresponding to the local status memory).

[0091] In another embodiment, if the user equipment moves to a new geospatial unit, it notifies its home network of its new location. In one example, the user equipment can update its own location information based on its positioning system. If it crosses a location block, the location information changes, and the user equipment will notify its home network to update its location information. In one example, this can be done by… Figure 7 The AMF implementation in the system. The home network will reassign the location IP address via PSA and current location. The user equipment updates its IP and establishes a new session.

[0092] In another embodiment, apart from location status, user equipment or satellites are prohibited from updating other states; that is, other states can only be updated by the home network. It employs public-key encryption for state protection and uses attribute-based encryption controlled by the home network.

[0093] In one example, during initialization, the home network prepares a key pair (pk, msk), generates a key for the authorized satellite based on its attribute set, and installs it on the satellite (before launch into space) and the user equipment (in the SIM card). For initial registration, the user equipment and the home network perform mutual authentication following a standard process. During this process, the home network encrypts the user equipment state using its private key pk and access tree A. A is specific to this user equipment and defines the satellite's access control policy. For subsequent services, the user equipment and its serving satellites run local authentication and key protocols by verifying their state / certificates, where this step can be automated. Figure 7 AUSF in local Complete, as shown in the diagram, is the security verification function. This allows the home network to specify access control policies based on user equipment and satellite attributes, thereby protecting local user equipment / satellites from unauthorized state access or modification.

[0094] Figure 3 This is a flowchart illustrating the state management process for running critical signaling of a satellite network under processing, based on a distributed local state library, provided by the present invention.

[0095] The following will combine Figure 3 The process of determining the state management flow of key signaling for satellite networks to be processed, based on a distributed local state database, is described.

[0096] In an exemplary embodiment of the present invention, the state management process may include a localized uplink session establishment process, a localized downlink session establishment process, and a state management process during mobility registration. Combined with... Figure 3 As can be seen, based on the distributed local state library, the state management process for running the critical signaling of the satellite network to be processed can include steps 310 to 330, which will be described in detail below.

[0097] In step 310, a localized uplink session establishment process is built and run based on the distributed local state library. The localized uplink session establishment process is used to transmit the target state of the distributed local state library to the satellite of the serving user equipment during session connection setup.

[0098] In yet another exemplary embodiment of the present invention, continuing with Figure 3 Taking this as an example, after step 310, the network element status management method may also include:

[0099] When the home network authorizes satellite access to the target state, the state of the encrypted distributed local state database is decrypted based on the public key to obtain the data information corresponding to the state;

[0100] If the target state is not authorized by the home network for satellite access, roll back to the pre-set standard procedure based on the home network.

[0101] In one embodiment, a localized uplink session establishment process can be built and run based on a distributed local state database, utilizing a copy of the user equipment's state for localized session establishment. In one example, the user equipment propagates its state along-path to the LEO satellite serving it during session connection setup. If the home network authorizes access to this state, the serving satellite can successfully decrypt and install it on the satellite to immediately provide data services. This process can be performed by... Figure 7 The status agent shown in the image has completed.

[0102] Otherwise, if the serving satellite cannot decrypt these states, it will roll back to standard procedures by contacting the home network, such as... Figure 7 As shown, the home network implements 5G standard functions such as AUSF (Authentication Service Function), UDM (Unified Data Management), AMF (Access and Mobility Management Function), SMF (Session Management Function), and PCF (Policy Control Function).

[0103] In step 320, based on the target location status, a localized downlink session establishment process is constructed and executed, and fixed anchor gateways in the satellite network to be processed are removed. Stateless data forwarding between satellites is then performed using the user equipment IP address, which includes the target geographical location. Figure 6 The stateless core data plane of the China Satellite can be specifically defined as follows: Figure 7 The stateless satellite network in the UPF forwards the message.

[0104] In one embodiment, a localized downlink session establishment process can be built and run based on the target location status, removing the fixed anchor gateway and using geolocation-based IP addresses for stateless data forwarding between satellites. Removing the fixed anchor gateway can alleviate single-point bottlenecks in the network.

[0105] In the application process, stateless data forwarding between satellites is carried out using IP addresses based on geographic location. By comparing the address of the destination user equipment with the current operating position of the satellite, each satellite can estimate its physical distance from the destination and determine the next hop satellite, thereby determining the forwarding path and realizing stateless data forwarding.

[0106] In step 330, a mobility registration state management process is constructed and run based on the distributed local state library and the target location state. The mobility registration state management process is used to eliminate re-registration caused by satellite dynamics. When the user equipment is switched from one satellite to another, a state copy of the distributed local state library is carried in the switchover confirmation information to other satellites based on the distributed local state library to achieve state migration.

[0107] In one embodiment, a state management process for mobility registration can be built and run based on a distributed local state library and the target location state to eliminate re-registration caused by satellite hyperdynamics. During application, for handovers triggered by satellite hyperdynamics, the user equipment's local state library enables faster state transitions.

[0108] In one example, the geospatial service area is decoupled from the satellite. Regardless of the serving satellite, the service area of ​​a static user equipment (UE) remains unchanged, thus eliminating orbital area updates due to satellite movement and avoiding significant signaling migrations. For inter-satellite handover, the UE switches from one satellite to another. The new satellite should install the UE's state to maintain seamless, continuous data service. Once the UE switches to the new satellite, it carries a copy of its state in the handover confirmation message to the new satellite. This results in an equivalent but shorter state migration path.

[0109] To further introduce the network element status management method provided by this invention, the following will be combined with... Figures 8 to 11The signaling process diagram shown illustrates the optimization process of the session establishment and mobility registration signaling process described in this invention.

[0110] In one embodiment, the session establishment process may include: initial registration, uplink session establishment, and downlink session establishment steps, which will be described in detail below.

[0111] Initial registration:

[0112] In one embodiment, combined with Figure 8 As can be seen, each user equipment (UE) follows standard procedures for mobile networks for authentication, security key protocols, state creation, and session setup for remote terrestrial homes. During this process, the home network maintains complete control over each UE's data forwarding, QoS, billing, and security by generating session states according to these policies. Upon successful registration, the home network assigns a geospatial IP address to the UE, encrypts these states according to its satellite access control policies, and hosts them to the local UE; this process is forwarded via a GTP-U tunnel.

[0113] Uplink session establishment:

[0114] In one embodiment, combined with Figure 9 It is known that this process is invoked when a user equipment (UE) wants to send data but does not have an active session connection with its serving satellite. This invention utilizes a copy of the UE's state to localize session establishment. During session connection setup, the UE routes a copy of its state to the LEO satellite serving it, which can be achieved by reusing the UE's AT commands. If the home network has authorized access to these states, the serving satellite can successfully decrypt them and install them into its local radio access and UPF functions to immediately provide data service, achieving decoupling of state, function, and location. Otherwise, the serving satellite cannot decrypt these states and rolls back to standard procedures by contacting the home network.

[0115] Downlink session establishment:

[0116] In one embodiment, combined with Figure 9 This process occurs when a user equipment (UE) should receive its data but lacks an active session connection with a satellite. This invention pushes data service to the satellite edge and eliminates mobile fixed-anchor gateways. Instead, it employs geospatial units for stateless data forwarding between satellites. By comparing the destination UE's address and runtime location, each satellite can estimate its physical distance to the destination and determine the next-hop satellite.

[0117] In another embodiment, the mobility registration process may include steps such as handover caused by satellite hyperdynamics, elimination of mobility registration, and handover / mobility registration triggered by user equipment mobility. Each step will be described in detail below.

[0118] Switching caused by satellite high dynamics:

[0119] In one embodiment, a static user equipment with an active session connection may face two types of handover: (1) beam handover, where the user equipment switches from one antenna to another on the same satellite. This occurs at the physical layer without core state operation; (2) inter-satellite handover, where the user equipment switches from one satellite to another. Figure 10 As shown, the new satellite should carry the user equipment state to maintain seamless and continuous data service. In this invention, once switched to the new satellite, the user equipment carries a copy of its state in the handover confirmation message to the new satellite. This results in an equivalent but shorter state transition path.

[0120] Eliminate mobility registration:

[0121] Unlike traditional stateful designs, this invention eliminates orbital area updates caused by moving satellites because it decouples the geospatial service area from the satellites. The service area of ​​a static user equipment remains unchanged regardless of the serving satellite, and therefore requires no updates. In this way, the invention avoids a significant amount of state transitions.

[0122] Handover / mobility registration triggered by user equipment mobility:

[0123] It's important to note that both occur only when a user equipment (UE) traverses a geospatial cell. In this case, the UE should update its location to its distant home network. This process follows standard procedures to re-authenticate the UE, reassign its geospatial IP address, and potentially update QoS / billing status based on the new location's policies. The UE will receive the updated status to obtain service later in this block.

[0124] In another embodiment, the present invention can also support the home network's control and updating of the state, which will be discussed below. Figure 11 The steps will be explained.

[0125] The home network receives dynamic data usage reports from remote satellites, runs its policy control functions, and uses a session modification procedure to update the session state to reflect the local user equipment and serving satellites. If a user equipment moves to a new geospatial unit, it notifies the home network of its new location.

[0126] Meanwhile, to reduce sensitive security state leakage, this invention entrusts most authentication and critical protocols to local user equipment and edge satellites. This invention employs public-key encryption for local state protection and uses attribute-based encryption (ABE) over the home network. It allows the home to specify access control policies based on user equipment and satellite attributes, thereby protecting against unauthorized access to or modification of the state of local user equipment / satellites.

[0127] Figure 4 This invention provides a schematic diagram of the process for obtaining a stateless space-ground integrated mobile network corresponding to the satellite network to be processed, based on mobile network location status, a distributed local state database, and a state management process.

[0128] The following will combine Figure 4 The network element status management method provided by this invention will be described.

[0129] In an exemplary embodiment of the present invention, combined with Figure 4 As can be seen, obtaining the stateless space-ground integrated mobile network corresponding to the satellite network to be processed based on the mobile network location status, distributed local state library and state management process may include steps 410 to 430, and each step will be described below.

[0130] In step 410, based on the mobile network location status, the distributed local state library, and the state management process, the home network of the satellite network to be processed is replaced with the target home network.

[0131] In step 420, the target home network is used as a shared home network for both the terrestrial network and the satellite.

[0132] In step 430, a stateless space-ground integrated mobile network corresponding to the satellite network to be processed is obtained based on the shared home network of the terrestrial network and the satellite.

[0133] In one embodiment, the home network of the satellite network to be processed can be replaced with the target home network based on the mobile network location status, a distributed local state database, and a state management procedure; that is, the terrestrial mobile core can be used as its home network. Since the state management procedure is built upon standard 5G core network functions and signaling procedures, it is backward compatible with traditional terrestrial 5G. Figure 7 In this configuration, user equipment retains the standard 5G protocol stack, ensuring backward compatibility for users. Furthermore, the terrestrial home core network can be accessed by both satellites and terrestrial 5G base stations, thus merging space-terrestrial networks.

[0134] In another embodiment, the operator's existing terrestrial mobile core network can be connected to the satellite ground station, its IP address allocation policy updated to geolocation-based IP, and support for policy-based user equipment state encryption added. In one example, initial registration and session setup do not involve interaction between satellite and terrestrial 5G. For mobility registration between space and terrestrial infrastructure, the terrestrial home will coordinate the satellite and terrestrial base stations. When a user equipment does not have an active connection to the infrastructure (i.e., idle state), it runs a standard block reselection to switch its connection between space and terrestrial base stations. Otherwise (i.e., connected state), the handover from space to terrestrial base stations (and vice versa) follows standard 5G handover controlled by the home network.

[0135] This invention supports seamless integration with terrestrial 5G networks. This is because the invention is built upon standard 5G core network functions and signaling procedures, thus ensuring backward compatibility with traditional terrestrial 5G. Secondly, the terrestrial home network of this invention is accessible to both satellites and terrestrial 5G base stations, thereby promoting space-terrestrial network convergence.

[0136] In yet another embodiment, the fusion of the terrestrial network and the satellite core network may further include the following steps:

[0137] Operators connect their existing terrestrial mobile cores to satellite ground stations, update their IP address allocation policies to geospatial unit-based satellite user equipment, and add support for policy-based user equipment state encryption.

[0138] For mobility registration between space and terrestrial infrastructure, this invention first integrates the terrestrial home core network into the terrestrial 5G infrastructure structure. This integration is easily achieved because the terrestrial home network of this invention follows conventional 5G.

[0139] When a user equipment (UE) is not actively connected to the infrastructure (i.e., in an idle state), it performs a standard block reselection to switch its association between space and terrestrial base stations. Otherwise (i.e., in a connected state), note that the home (core) network of this invention is a natural controller of space and terrestrial nodes. The handover from space to terrestrial base stations (and vice versa) follows standard 5G handover.

[0140] The network element status management method provided by this invention decouples function from location, which is beneficial for all signaling processes involving signaling migration, such as session establishment, registration, and handover in mobile networks. It supports home network status updates and seamless integration of satellite and traditional terrestrial mobile networks.

[0141] As described above, the network element state management method provided by this invention effectively reduces state migration by decoupling the service area in the satellite network to be processed from the preset satellites and defining the service area as a geographical location region. Furthermore, by entrusting other states of the satellite network to be processed to local user equipment to obtain a distributed local state library, and then based on the mobile network location state, the distributed local state library, and the state management process, a stateless terrestrial-space integrated mobile network corresponding to the satellite network to be processed can be obtained. This achieves a stateless terrestrial-space integrated mobile core network, thereby improving the performance of the mobile network and avoiding signaling storms.

[0142] Based on the same concept, the present invention also provides a network element status management device.

The stateless terrestrial-satellite integrated mobile network is a network consisting of satellite and terrestrial networks that has not undergone state migration.

[0151] In an exemplary embodiment of the present invention, the second module 1220 may determine the mobile network location status of the satellite network to be processed based on the geographic location area in the following manner:

[0152] Determine the target geographical location based on the geographic location area;

[0162] Other states are required during the satellite service user equipment process, and other states are retrieved from the local state storage of the local user equipment when the satellite is authorized to access the distributed local state library.

[0167] Public keys are used to encrypt and protect each distributed local state database, and attribute-based encryption controlled by the home network is used to allow the home network to formulate access control policies to prevent unauthorized access or modification of state by other user equipment and / or other satellites. The access control policies are determined based on the user equipment and satellite.

[0168] In an exemplary embodiment of the present invention, the state management process may include a localized uplink session establishment process, a localized downlink session establishment process, and a state management process during mobility registration.

[0169] Module 1240 can run the state management process for critical signaling of the satellite network to be processed based on a distributed local state library in the following manner:

[0170] Based on a distributed local state library, a localized uplink session establishment process is built and run.
