[0034] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] In related technologies, satellites are used to provide access or backhaul links for 5G NR (New Radio). Terminals connect solely to high-orbit satellites or directly to aircraft within the coverage area of ​​high-orbit satellites. In other words, terminals only select one type of satellite connection between high-orbit satellites and aircraft within the coverage area of ​​high-orbit satellites. Due to the high orbital speed of aircraft within the coverage area of ​​high-orbit satellites, terminals sometimes need to switch to aircraft within the coverage area of ​​high-orbit satellites, and the aircraft feeder link is easily disconnected, resulting in interruption of communication services.

[0041] The present disclosure provides a registration method for user equipment, which enables the user equipment to simultaneously access a high-orbit satellite and an aircraft within the coverage area of ​​the high-orbit satellite, thereby ensuring the continuity of communication services.

[0042] FIG1 shows a flowchart of a method for registering a user equipment according to some embodiments of the present disclosure.

[0043] As shown in Figure 1, the registration method for user equipment includes steps S1 to S5. The registration method for user equipment is executed by a NACF (Network Access Control Function) network element.

[0044] In step S1, in response to receiving a registration request (Registration Request) from a user equipment, a subscription data acquisition request is sent to a USM (USM Unified Subscription Management) network element.

[0045] The registration process is initiated by UE (user equipment).

[0046] In some embodiments, a user equipment registration request is received by a base station on a high-orbit satellite. For example, when a UE (e.g., a terminal) initiates a registration process, it first sends a registration request to the base station on the high-orbit satellite. The base station then forwards the registration request to the network access control element on the high-orbit satellite. The registration request includes the user equipment's location information.

[0047] In response to receiving a registration request of the user equipment from the base station of the high-orbit satellite, the network access control network element sends a subscription data acquisition request to the unified subscription management network element.

[0048] In step S2, an aircraft providing connection services for the user equipment is selected based on the subscription data (Satellite Subscription data) of the user equipment received from the unified subscription management network element, wherein the aircraft is located within the coverage of the high-orbit satellite.

[0049] For example, the network access control network element interacts with the unified subscription management network element. During the user data acquisition phase, the unified subscription management network element returns the subscription data of the user equipment.

[0050] Compared with the current 3GPP standard, the subscription data includes additional subscription data, such as satellite subscription data. The high-orbit and aircraft dual-connection authorization information in the subscription data is used to instruct the user equipment to enable dual connection with the high-orbit satellite and the aircraft within the high-orbit satellite coverage area.

[0051] In some embodiments, the aircraft within the coverage of the high-orbit satellite includes a low-orbit satellite or a high-altitude platform within the coverage of the high-orbit satellite.

[0052] In some embodiments, the subscription data of the user equipment includes dual connection authorization information of the high orbit and the aircraft, such as dual connection authorization information of the high orbit and the low orbit (LEO and GEO Dual Connection Authorization).

[0053] In some embodiments, the contract data of the user device also includes authorization information of the aircraft, such as low orbit service authorization information (LEO service Authorization), high orbit service authorization information (GEO service Authorization), subscribed high orbit access user equipment side aggregate maximum bit rate (Subscribed GEO-UE-AMBR), and at least one of the access user equipment side of the aircraft (for example, subscribed low orbit access user equipment side aggregate maximum bit rate (Subscribed LEO-UE-AMBR)).

[0054] For example, the contract data includes satellite service authorization data (Satellite Service Authorization), and the satellite service authorization data includes high-orbit service authorization information (contract information of high-orbit satellite services of user equipment), contract information of aircraft services within the coverage of high-orbit satellites (including contract information of aircraft services within the coverage of high-orbit satellites of user equipment), and dual-connection authorization information of high-orbit and aircraft (contract information of user equipment simultaneously accessing high-orbit satellites and low-orbit satellites / high-altitude platforms).

[0055] The data key for the Subscribed GEO-UE-AMBR and the Subscribed LEO-UE-AMBR is SUPI (Subscription Permanent Identifier).

[0056] The unified subscription management network element stores user device subscription data. Operators can add, delete, or modify user device subscription data in the unified subscription management network element. The unified subscription management network element can also search for user device subscription data when a user device registers with the network.

[0057] In some embodiments, an aircraft that provides connection services to the user equipment is selected based on the contract data of the user equipment received from the unified contract management network element, including: selecting an aircraft that provides connection services to the user equipment based on the location information (location info) of the user equipment, TA (Tracking Area), at least one item of information of the base station of the aircraft connected to the network access control network element, and the contract data of the user equipment received from the unified contract management network element.

[0058] For example, the network access control network element selects a base station of one aircraft from one or more base stations of the aircraft to provide connection for the user equipment based on the above-mentioned contract data, the location information of the user equipment, the information of the base stations of one or more aircraft connected to the network access control network element, etc.

[0059] In step S3, an access network resource request (AN Resource Request) is sent to the base station of the aircraft, wherein the access network resource request (also known as the negotiation terminal low-orbit communication resource allocation request) is used by the base station of the aircraft to allocate communication resources and aircraft access information to the user equipment, such as low-orbit access information (LEO Access Info).

[0060] In response to receiving the access network resource request, the base station of the aircraft reserves resources for the user equipment and returns the aircraft access information of the user equipment to the network access control element.

[0061] In some embodiments, the access network resource request includes a subscription permanent identifier of the user equipment. The base station of the aircraft reserves resources for the user equipment based on the subscription permanent identifier of the user equipment, and returns access information of the aircraft corresponding to the subscription permanent identifier of the user equipment to the network access control element.

[0062] In step S4 , access information of the aircraft, for example, low orbit access information (LEO Access Info), is received from the base station of the aircraft.

[0063] In some embodiments, the access information of the aircraft includes at least one of the following: an access number (Access No), an access token (Access Token), an access frequency (Access Frequency), an identifier of the base station of the aircraft (cell id), and an identifier of the aircraft (for example, an identifier of an aircraft of a low-orbit satellite, Satellite ID).

[0064] In step S5, a registration acceptance message (Registration Accept) is sent to the user equipment, wherein the registration acceptance message includes dual connection authorization information of the high-orbit and aircraft, and access information of the aircraft. The registration acceptance message is used by the user equipment to access the communication system of the aircraft and the high-orbit satellite.

[0065] In some embodiments, sending the registration acceptance message to the user equipment includes: sending the registration acceptance message to the user equipment via a base station of a high-orbit satellite. For example, the network access control element returns the registration acceptance message to the user equipment via the base station of the high-orbit satellite.

[0066] In some embodiments, when a registration completion message is received from a user device through a base station of a high-orbit satellite, and a registration completion message is received from a user device through a base station of an aircraft, the network access control network element confirms that the terminal has successfully accessed the communication system of the aircraft and the high-orbit satellite.

[0067] For example, the user device returns a registration completion message to the network access control element via the high-orbit satellite's base station. Simultaneously, the user device connects to the aircraft's base station using the aircraft's access information and returns a registration completion message to the network access control element via the aircraft's base station. Upon receiving both the registration completion message forwarded by the high-orbit satellite's base station and the aircraft's base station, the network access control element determines that the user device has registered and connected to the communication systems of both the high-orbit satellite and the aircraft, achieving dual connectivity between the high-orbit satellite and the aircraft.

[0068] FIG2 shows an interaction diagram of a registration process of a user device according to some embodiments of the present disclosure.

[0069] As shown in Figure 2, the user equipment first establishes a connection with the high-orbit satellite. During the registration process, the user equipment sends a registration request to the base station of the high-orbit satellite. The base station of the high-orbit satellite then selects a network access control element that provides services and forwards the message to the selected network access control element.

[0070] The network access control network element selects the unified contract management network element and sends a terminal connection management request, a contract data management acquisition request, and a contract data management subscription request to the unified contract management network element, thereby interacting with the unified contract management network element to perform registration service operations (Nudm_UECM_Registration service operation), acquisition service operations (Nudm_SDM_Get service operation), and subscription service operations (Nudm_SDM_Subscribe service operation).

[0071] In the service acquisition operation, the unified subscription management network element finds the subscription data of the user equipment according to the SUPI of the user equipment, encapsulates the subscription data in the return message corresponding to the subscription data management acquisition request, and sends it to the network access control network element.

[0072] The contract data is shown as follows:

[0073] Satellite Subscription data = {

[0074] Satellite Service Authorization = {LEO service Authorization = True;

[0075] GEO service authorization = True;

[0076] LEO and GEO Dual Connection Authorization = True;

[0077] Subscribed GEO-UE-AMBR = 2 Mbps.

[0078] Subscribed LEO-UE-AMBR = 5Mbps

[0079] After receiving the subscription data, the network access control network element selects a base station of an aircraft based on the subscription data, TA, location information, and information of the base station of the aircraft connected to the core network, for example, the base station identifier is 33011.

[0080] The network access control element then sends an access network resource request to the aircraft's base station 33011. The access network resource request includes information such as the user equipment's SUPI. The aircraft's base station 33011 reserves resources for the user equipment and returns the aircraft's access information to the network access control element. For example, if the aircraft is a low-orbit satellite, the aircraft's access information is represented as follows:

[0081] (Low-orbit satellite access information) = {Access sequence number = 001, Access token = 123456789, Access frequency = 1990 MHz, Aircraft base station ID = 33011, Low-orbit satellite ID = 460031}

[0082] The network access control network element then returns a registration acceptance message to the user equipment through the base station of the high-orbit satellite. The registration acceptance message carries the dual connection authorization information of the high-orbit and aircraft, and the access information of the aircraft.

[0083] In response to receiving the registration acceptance message, the user equipment returns a registration completion message to the network access control network element through the high-orbit satellite base station. At the same time, the user equipment connects to the aircraft base station and also returns a registration completion message through the aircraft base station.

[0084] When the network access control network element receives the registration completion message sent by the user equipment from the base station in the high orbit and the base station in the aircraft respectively, it considers that the user equipment has completed the registration.

[0085] In some embodiments, the network access control network element is located on a high-orbit satellite. The network access control network element deployed on the high-orbit satellite can receive and parse user device subscription data returned by the unified subscription management network element; select an aircraft base station for the user device based on the user device subscription data, user device location information, and information such as the base station of the aircraft connected to the network access control network element; negotiate with the aircraft base station resources to reserve wireless air interface resources for the user device; receive aircraft access information returned by the aircraft base station and send it to the user device; return high-orbit and aircraft dual-connection authorization information to the user device; and receive registration completion messages returned by the user device from the high-orbit and aircraft, respectively, and deem the user device registration successful.

[0086] In some embodiments, the unified contract management network element is located on a high-orbit satellite.

[0087] Because high-orbit satellites have a large coverage area, they can reach aircraft within a wider range. Compared to terminals searching directly for (low-orbit) aircraft, high-orbit satellites make it easier to find low-orbit aircraft. By placing core network elements on high-orbit satellites, high-orbit satellites assist in aircraft selection, replacing the terminal's resource negotiation with the aircraft. This ensures the stability of the registration and access process between user devices and aircraft.

[0088] According to the registration method of a user device in some embodiments of the present disclosure, the network access control network element sends a contract data acquisition request to the unified contract management network element in response to receiving a registration request from the user device; selects an aircraft to provide connection services for the user device based on the contract data of the user device received from the unified contract management network element, wherein the contract data of the user device includes dual connection authorization information of the high orbit and the aircraft; sends an access network resource request to the base station of the aircraft within the coverage of the high orbit satellite, wherein the access network resource request is used for the base station of the aircraft to allocate resources and access information of the aircraft to the user device; receives the access information of the aircraft from the base station of the aircraft; sends a registration acceptance message to the user device, wherein the registration acceptance message includes dual connection authorization information of the high orbit and the aircraft and the access information of the aircraft, and the registration acceptance message is used for the user device to access the communication system of the high orbit satellite and the aircraft.

[0089] Through the above method, user equipment can simultaneously access aircraft in high orbit and those within the coverage of high orbit satellites. Services can be forwarded through aircraft or high orbit, ensuring business continuity and availability, and realizing the collaboration between high orbit and low orbit aircraft. When high and low orbit aircraft are connected at the same time, user equipment can give priority to low orbit aircraft within the coverage of high orbit satellites for traffic forwarding to meet service latency requirements. When the low orbit aircraft switches and the low orbit aircraft feeder link is disconnected, the connected high orbit satellite can ensure business continuity, thereby avoiding business interruption. It is an important solution for the 6G space-ground integrated high and low orbit collaborative networking architecture.
