Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information transmission method, apparatus, related equipment, storage medium, and computer program product. Background Technology

[0002] Existing networks of different standards, such as the fourth generation mobile communication technology (4G), the fifth generation mobile communication technology (5G), and the sixth generation mobile communication technology (6G), are either independent of each other or connected through a dual connectivity mechanism.

[0003] In the case of multiple network standards coexisting, if each standard is built independently, that is, a complete end-to-end network needs to be built, which will bring higher construction costs. If dual connectivity technology is used, it is necessary to distinguish between primary and secondary nodes. However, the secondary node does not have full-function connectivity with the core network (i.e., it does not have a control plane), and the radio resource control (RRC) of the secondary node is not full-function, only responsible for generating the signaling radio bearer (SRB). However, there is only one RRC on the user equipment (UE) side.

[0004] Therefore, for a UE to establish connections and perform registrations with different types of Radio Access Networks (RANs) and core networks, multiple registrations and connection establishments are required through registration updates and node updates to maintain connectivity across multiple network types. However, this process of multiple registrations and connection establishments through registration updates and node updates inevitably consumes significant signaling overhead.

[0045] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0047] This application provides an information transmission method, which is applied to a first RAN node, the first RAN node corresponding to a first network standard. Figure 1 This is a flowchart illustrating the information transmission method according to an embodiment of this application. Figure 1 ;like Figure 1 As shown, the method includes:

[0048] Step 101: Send the first message to the terminal.

[0049] Step 102: Receive the second information sent by the terminal; the second information represents registration request information for requesting registration of one or more network standards.

[0050] Here, the first information is used by the terminal to determine one or more of the following: one or more target cells providing services; connection activation information; and network standard information of the target cells. Thus, when the first RAN node receives the registration request information sent by the terminal, it can also receive the candidate target cell / RAN node list, priority attributes, frequency information, etc., reported by the terminal simultaneously under the corresponding network standard.

[0051] In this application embodiment, the one or more network standards include the first network standard and / or one or more network standards of other types besides the first network standard, wherein the other types of one or more network standards correspond to one or more RAN nodes of other types besides the first RAN node, and the other types of one or more RAN nodes are in a terrestrial network (TN) or a non-terrestrial network.

[0052] Here, the terminal can communicate with RAN nodes of one or more network standards, where the RAN node can be a base station. When the network standard includes multiple types of network standards, the terminal can communicate with RAN nodes of these multiple types of network standards simultaneously. Specifically, the terminal can maintain RRC connections with RAN nodes of these multiple types of network standards simultaneously, and at least two of these RRC connections are independent of each other.

[0053] It should be noted that the first network standard can also be referred to as the first communication standard, or simply the first standard. For example, the first network standard can be a 5G network. Other types of network standards besides the first network standard can also be, for example, 4G or 6G networks. Correspondingly, the first RAN node can be a network device corresponding to the 5G network, such as a 5G RAN node (i.e., a 5G base station). Other types of RAN nodes besides the first RAN node can be network devices corresponding to 4G or 6G networks, such as a 4G RAN node (i.e., a 4G base station) or a 6G RAN node (i.e., a 6G base station). This application embodiment does not limit the type of network standard.

[0054] Taking 5G as the primary network standard and 6G as the secondary network standard, the following explanation illustrates how non-terrestrial 5G / 6G base stations and terrestrial 5G / 6G base stations can access the same or different core network elements. If they access the same core network element, that element supports both 5G and 6G functions, meaning it's a shared core network element across multiple network standards. If they access different core network elements, the 5G base station accesses the 5G core network (5GC, 5G CoreNetwork), and the 6G base station accesses the 6G core network (6GC, 6G Core Network). Terminals can simultaneously access both 5G RAN nodes and 6G RAN nodes (i.e., simultaneously access both 5G and 6G base stations), and there is a (sequence) association between the 5G RAN nodes and 6G RAN nodes. The terminal maintains multiple RRC states, such as 4G RRC states, 5G RRC states, and 6G RRC states. Among them, the 5G RRC states include: connected, inactive, and idle; the 6G RRC states include: connected, inactive, power saving, and idle.

[0055] In practical applications, the first RAN node can send the first information by including it in a system message.

[0056] Based on this, in one embodiment, sending the first information to the terminal includes: broadcasting the first information to the terminal via a system message;

[0057] The first information includes one or more of the following: ephemeris information; network type information; satellite service time information; satellite orbit information; timing advance (TA) pre-compensation parameter information; and network connection activation / deactivation indication information.

[0058] Here, ephemeris information can be a list of satellite nodes, network standard category information includes a first network standard (e.g., 5G network) and one or more other network standards besides the first network standard (e.g., 6G network), network connection activation indication information is used to activate RAN / CN connections with valid service, and network connection deactivation indication information is used to deactivate RAN / CN connections with invalid service.

[0059] Here, the first information is obtained by the first RAN node from one or more other types of RAN nodes through a first interface. For example, the first interface can be an inter-base station interface, meaning the first RAN node can obtain the first information from one or more other types of RAN nodes through the inter-base station interface and broadcast the first information to the terminal via a system message. The first information represents NTN RAN auxiliary information. The first RAN node is located in a non-terrestrial network, and non-terrestrial networks, such as satellite nodes, have predictable characteristics. The other types of RAN nodes can be located in a non-terrestrial network or in a terrestrial network.

[0060] In one embodiment, when the first information includes network connection activation indication information, the method further includes: activating corresponding network connections at different times based on the network connection activation indication information; wherein the network connection includes the connection between the one or more network standards and the terminal.

[0061] Here, by activating the corresponding network connection at different times to establish a connection between one or more network standards and the terminal, different network standards provide different types of service to the terminal in terms of carrying. Furthermore, if the connection between a certain network standard and the terminal is lost, the service can be obtained seamlessly through the connection between other network standards and the terminal, reducing the overhead of switching between different network standards.

[0062] In practical applications, the terminal uses the corresponding RAN node to connect with the terminal and the RAN node to the core network during the corresponding service time, based on the satellite service time information in the NTN RAN auxiliary information (i.e., the first information) provided by the network side, i.e. the first RAN node.

[0063] Based on this, in one embodiment, if the first information also includes satellite service time information, the method further includes: sending the service time information to the terminal so that the terminal uses the network connection within the service time information;

[0064] The service time information includes one or more of the following: service start time information; service end time information; service time period information.

[0065] Here, if the service time information is a specific execution time point, i.e., the start time of service, then the corresponding network connection becomes effective at that time, and the terminal and network automatically align their information. If the service time information is a time period (i.e., service time period information) or a service termination time point (i.e., service termination time point information), then after the corresponding network connection becomes available, the terminal sends an uplink message to align the terminal and network information. It should be noted that the network can provide a valid connection before the service termination time point, meaning that the terminal can perform data transmission and reception operations with the corresponding network at any time before the service termination time point.

[0066] Based on this, in one embodiment, after activating the corresponding network connection at different times based on the network connection activation indication information, the method further includes: receiving sixth information sent by the terminal; the sixth information represents an uplink message; wherein the sixth information includes one of the following: TA report information; random access preamble information; random access request information initiated by the terminal (i.e., the terminal initiates a random access procedure).

[0067] Step 103: Send the second information to the target core network element so that the target core network element can register the one or more network standards based on the second information.

[0068] In this embodiment of the application, the target core network element includes one or more core network elements, and the one or more core network elements correspond to the one or more network standards; wherein, when the target core network element includes one core network element, the target core network element represents a core network element used for sharing by the one or more network standards.

[0069] Here, when the target core network element includes one type of core network element, the core network element simultaneously supports the functions of one or more network standards. That is, the core network element has a one-to-many relationship with one or more network standards. When the target core network element includes multiple types of core network elements, the multiple types of core network elements have a one-to-one correspondence with one or more network standards. For example, 5GC corresponds to 5G network, and 6GC corresponds to 6G network.

[0070] Here, the information transmission method of this application embodiment can be applied to NTN only scenarios, that is, RAN nodes of different network standards are all in NTN; it can also be applied to NTN-TN scenarios, that is, RAN nodes of different network standards are in NTN and TN respectively. In general, the first RAN node corresponding to the first network standard needs to be in NTN, and one or more RAN nodes of other types corresponding to one or more network standards need to be in TN.

[0071] In practical applications, for scenarios where RAN nodes of different network standards are all located within the NTN, there are two scenarios. The first scenario involves multiple core network elements, where one or more network standards correspond to one or more core network elements respectively. The second scenario involves a single core network element, where all network standards share one core network element. The collaborative registration process for multiple network standards under these two scenarios will be explained in detail below.

[0072] In practical applications, for the first scenario mentioned above, the target core network element can adopt a different network standard registration process corresponding to different auxiliary information based on the auxiliary information of the first network standard carried in the second information or auxiliary information of one or more other types of network standards.

[0073] Based on this, in one embodiment, when the target core network element includes multiple core network elements, the multiple core network elements include a first core network element and one or more core network elements of other types besides the first core network element. The first core network element corresponds to the first network standard, and the other types of core network elements correspond to the other types of one or more network standards. The second information includes auxiliary information of the first network standard and auxiliary information of one or more other types of network standards.

[0074] Sending the second information to the target core network element so that the target core network element can register the one or more network standards based on the second information includes:

[0075] If the second information includes auxiliary information for the first network standard, the second information is sent to the first core network element so that the first core network element can register the first network standard.

[0076] When the second information includes auxiliary information for one or more other types of network standards, the second information is sent to one or more other types of core network elements through the first core network element, so that the other types of core network elements can register for one or more other types of network standards.

[0077] Here, the auxiliary information for the first network standard includes a candidate cell / RAN node list under the first network standard (i.e., the first RAN node list information), the corresponding priority attribute, the corresponding frequency point information, and the service time information. The priority attribute can be determined based on the distance between the terminal and the satellite cell reference point and the length of the satellite's service time. The auxiliary information for one or more other types of network standards includes the standard information for one or more other types of network standards, a candidate cell / RAN node list under one or more other types of network standards (i.e., one or more RAN node list information of other types), the corresponding priority attribute, the corresponding frequency point information, and the service time information.

[0078] It should be noted that the second information also includes terminal capability information, which includes the types of network standards supported by the terminal and the number of connections of different network standards that the terminal can maintain simultaneously.

[0079] In one embodiment, sending the second information to the first core network element to enable the first core network element to register the first network standard includes: sending the second information to the first core network element to enable the first core network element to create corresponding terminal context information for the terminal and to feed back third information to the terminal; wherein the third information includes registration acceptance information for the request to register the first network standard.

[0080] Here, when the registration request information only includes auxiliary information for the first network standard, the first RAN node (e.g., RAN node 1 of standard 1) sends the registration request information to the first core network element (e.g., core network element 1 of standard 1). After receiving the registration request information, core network element 1 of standard 1 creates corresponding terminal context information (i.e., UE context) for the terminal and feeds back the registration acceptance information for the request to register standard 1 to the terminal.

[0081] In one embodiment, the step of sending the second information to one or more other types of core network elements through the first core network element, so that the other types of core network elements can register for one or more other types of network standards, includes: sending the second information to the first core network element, forwarding the second information to one or more other types of core network elements through the first core network element, so that the other types of core network elements can create corresponding terminal context information for the terminal and feed back fourth information to the terminal.

[0082] Here, when the registration request information includes auxiliary information of one or more other types of network standards, the first RAN node (e.g., RAN node 1 of standard 1) sends the registration request information to the first core network element (e.g., core network element 1 of standard 1). After receiving the registration request information, core network element 1 of standard 1 forwards the registration request information to one or more other types of core network elements (e.g., core network element 2 of standard 2). Then, core network element 2 of standard 2 creates a set of corresponding terminal context information (i.e., UE context) for the terminal and feeds back the fourth information to the terminal.

[0083] In this embodiment of the application, the fourth information includes one or more of the following: registration acceptance information for requesting registration of one or more network standards of other types; and information on one or more RAN nodes of other types other than the first RAN node corresponding to the other types of network standards.

[0084] In one embodiment, the fourth information is fed back to the terminal in one or more of the following ways:

[0085] The fourth information is fed back to the terminal through one or more RAN nodes of other types;

[0086] The first core network element feeds back third information to the terminal. The third information includes registration acceptance information for the request to register the first network standard and the fourth information. The fourth information is forwarded to the first core network element by one or more other types of core network elements.

[0087] Here, the fourth information can be fed back to the terminal individually through RAN nodes of different network standards, or one or more other types of core network elements can forward the created terminal context information to the first core network element (e.g., core network element 1 of standard 1), and the first core network element (e.g., core network element 1 of standard 1) can feed back the fourth information to the terminal through the first RAN node (e.g., RAN node 1 of standard 1).

[0088] In practical applications, for the second scenario mentioned above, the target core network element can perform network registration for different network standards based on the auxiliary information of the first network standard carried in the second information and auxiliary information of one or more other types of network standards.

[0089] Based on this, in one embodiment, when the target core network element includes a core network element, the target core network element represents a shared core network element for sharing the one or more network standards.

[0090] Sending the second information to the target core network element so that the target core network element can register the one or more network standards based on the second information includes: when the second information includes auxiliary information of the first network standard and auxiliary information of one or more other types of network standards, sending the second information to the target core network element so that the target core network element can register the first network standard and one or more other types of network standards.

[0091] In one embodiment, sending the second information to the target core network element to enable the target core network element to register a first network standard and one or more other types of network standards includes: sending the second information to the target core network element to enable the target core network element to create corresponding terminal context information for the terminal and to feed back fifth information to the terminal; wherein, the fifth information includes registration acceptance information for requesting registration of a first network standard and one or more other types of network standards.

[0092] Here, the first RAN node (e.g., RAN node 1 of standard 1) sends a registration request to the target core network element (i.e., a shared core network element shared by one or more network standards). If the registration request contains auxiliary information of the first network standard and auxiliary information of one or more other types of network standards, the shared core network element performs network registration for different network standards. Specifically, after receiving the registration request, the shared core network element creates corresponding terminal context information (i.e., UE context) for the terminal for different network standards and feeds back registration acceptance information to the terminal for the request to register the first network standard and one or more other types of network standards.

[0093] In one embodiment, the fifth information is fed back to the terminal in one or more of the following ways:

[0094] In the case where the fifth information includes the third information and the fourth information, the third information is fed back to the terminal through the first RAN node, and the fourth information is fed back to the terminal through one or more other types of RAN nodes; the third information includes registration acceptance information for a request to register a first network standard, and the fourth information includes registration acceptance information for a request to register one or more other types of network standards;

[0095] The fifth information is fed back to the terminal through the first RAN node; the fifth information also includes one or more of the following:

[0096] Information on the first network standard and / or one or more other types of network standards;

[0097] RAN node information corresponding to the first network standard and / or one or more other network standards.

[0098] Here, RAN nodes of different network standards can respectively feed back registration acceptance information to the terminal. That is, RAN node 1 of standard 1 feeds back registration acceptance information for requesting to register for standard 1 to the terminal, and one or more RAN nodes of other types (such as RAN node 2 of standard 2) feed back registration acceptance information for requesting to register for one or more other types of network standards (such as registration acceptance information for requesting to register for standard 2) to the terminal; it is also possible to feed back registration acceptance information for requesting to register for the first network standard and one or more other types of network standards (such as registration acceptance information for requesting to register for standard 1 and standard 2) to the terminal through the first RAN node (such as RAN node 1 of standard 1). Here, the registration acceptance information fed back to the terminal through RAN node 1 of standard 1 includes standard information of multiple network standards and / or corresponding RAN node information.

[0099] In practical applications, for scenarios where RAN nodes of different network standards are located in NTN and TN respectively, the above-mentioned multi-network standard collaborative registration mechanism can also be used for multi-network standard registration. However, unlike the application scenario where RAN nodes of different network standards are all located in NTN, if the registration request is made through RAN node 1 of standard 1 (i.e., TN RAN node), the NTN auxiliary information is sent to the TN RAN node by RAN node 2 of standard 2 (i.e., NTN RAN node) through the inter-base station interface. The TN side cannot achieve multi-network standard collaborative registration (because the TN is not predictable). The TN RAN node can assist the NTN RAN node in completing the multi-network standard registration.

[0100] Accordingly, embodiments of this application also provide another information transmission method, which is applied to a terminal. Figure 2 This is a flowchart illustrating the information transmission method according to an embodiment of this application. Figure 2 ;like Figure 2 As shown, the method includes:

[0101] Step 201: Receive the first information sent by the first RAN node.

[0102] Step 202: Based on the first information, determine one or more of the following information: one or more target cells providing services; connection activation information; network standard information of the target cells.

[0103] Step 203: Send the second information to the first RAN node so that the first RAN node sends the second information to the target core network element, and the target core network element performs registration of one or more network standards based on the second information.

[0104] In this embodiment of the application, the target core network element includes one or more core network elements, wherein the first RAN node corresponds to a first network standard, the second information represents registration request information for requesting registration of the one or more network standards, the one or more network standards include the first network standard and / or one or more network standards of other types besides the first network standard, wherein the one or more network standards of other types correspond to one or more RAN nodes of other types besides the first RAN node, and the one or more RAN nodes of other types are located in a terrestrial network or a non-terrestrial network.

[0105] Here, the one or more core network elements correspond to the one or more network standards; wherein, when the target core network element includes a core network element, the target core network element represents a core network element used for sharing by the one or more network standards.

[0106] Here, the information transmission method of this application embodiment can be applied to NTN only scenarios, that is, RAN nodes of different network standards are all in NTN; it can also be applied to NTN-TN scenarios, that is, RAN nodes of different network standards are in NTN and TN respectively. In general, the first RAN node corresponding to the first network standard needs to be in NTN, and one or more RAN nodes of other types corresponding to one or more network standards need to be in TN.

[0107] Here, after receiving the first information, the terminal can determine one or more target cells that can provide services to the terminal, whether the connection is active, and the network standard information of the target cells based on the first information. In this way, when the terminal sends the registration request information to the first RAN node, it can simultaneously report the candidate target cell / RAN node list, priority attributes, frequency point information, etc. under the corresponding network standard to the first RAN node.

[0108] In practical applications, the first RAN node can send the first information by including it in a system message.

[0109] Based on this, in one embodiment, receiving the first information sent by the first RAN node includes: receiving the first information broadcast by the first RAN node through a system message; wherein the first information includes one or more of the following: ephemeris information; network standard category information; satellite service time information; satellite orbit information; TA pre-compensation parameter information; network connection activation / deactivation indication information.

[0110] Here, ephemeris information can be a list of satellite nodes, network standard category information includes a first network standard (e.g., 5G network) and one or more other network standards besides the first network standard (e.g., 6G network), network connection activation indication information is used to activate RAN / CN connections with valid service, and network connection deactivation indication information is used to deactivate RAN / CN connections with invalid service.

[0111] Here, the first information is obtained by the first RAN node from one or more other types of RAN nodes through a first interface. For example, the first interface can be an inter-base station interface, meaning the first RAN node can obtain the first information from one or more other types of RAN nodes through the inter-base station interface and broadcast the first information to the terminal via a system message. The first information represents NTN RAN auxiliary information. The first RAN node is located in a non-terrestrial network, and non-terrestrial networks, such as satellite nodes, have predictable characteristics. The other types of RAN nodes can be located in a non-terrestrial network or in a terrestrial network.

[0112] In practical applications, the terminal uses the corresponding RAN node to connect with the terminal and the RAN node to the core network during the corresponding service time, based on the satellite service time information in the NTN RAN auxiliary information (i.e., the first information) provided by the network side, i.e. the first RAN node.

[0113] Based on this, in one embodiment, when the first information includes satellite service time information, the method further includes: receiving the service time information sent by the first RAN node, and using an activated network connection within the service time information; wherein the network connection includes the connection between the one or more network standards and the terminal, and the service time information includes one or more of the following: service start time information; service end time information; service time period information.

[0114] Here, if the service time information is a specific execution time point, i.e., the start time of service, then the corresponding network connection becomes effective at that time, and the terminal and network automatically align their information. If the service time information is a time period (i.e., service time period information) or a service termination time point (i.e., service termination time point information), then after the corresponding network connection becomes available, the terminal sends an uplink message to align the terminal and network information. It should be noted that the network can provide a valid connection before the service termination time point, meaning that the terminal can perform data transmission and reception operations with the corresponding network at any time before the service termination time point.

[0115] Based on this, in one embodiment, when the network connection is active, the method further includes: sending sixth information to the first RAN node; the sixth information represents an uplink message; wherein the sixth information includes one of the following: TA report information; random access preamble information; random access request information initiated by the terminal.

[0116] In practical applications, considering the scenario of different operators, unlike the existing roaming mechanism, you can only switch to the service network of other operators if your own operator does not provide coverage.

[0117] Based on this, in one embodiment, when the network connection is in a deactivated state, the method further includes: switching from the deactivated network connection to a target network connection; the target network connection is in an active state, and the target network connection represents the network connection of an operator capable of providing corresponding service.

[0118] In practical applications, in one embodiment, before switching from the deactivated network connection to the target network connection, the method further includes: determining the target network connection;

[0119] Determining the target network connection includes one of the following: determining the target network connection based on the user's service requirements of the terminal; or determining the target network connection based on the relationship between the performance of the deactivated network connection and a performance threshold.

[0120] Here, the terminal can, based on business needs (e.g., wanting to access services provided by other operators), automatically activate a connection to the target network, i.e., automatically activate a connection to the network of the operator providing the corresponding service; or, a performance threshold-based operator service network connection switching can be introduced. The performance of the deactivated network connection can be its network speed; that is, the target network connection is determined based on the speed of the deactivated network. Specifically, if the current deactivated network speed is lower than a certain speed threshold, the terminal will choose to communicate with another registered operator network. It should be noted that the performance threshold can be preset according to actual needs, and this embodiment does not limit it.

[0121] This application also provides another information transmission method, which is an interaction method between the first RAN node and the terminal. Figure 3 This is a flowchart illustrating the information transmission method according to an embodiment of this application. Figure 3 ;like Figure 3 As shown, the method includes:

[0122] Step 301: The first RAN node sends the first information to the terminal.

[0123] Step 302: The terminal receives the first information sent by the first RAN node, and based on the first information, determines one or more of the following information: one or more target cells providing services; connection activation information; network standard information of the target cells.

[0124] Step 303: The terminal sends the second information to the first RAN node.

[0125] In this embodiment of the application, the second information represents registration request information for requesting registration of one or more network standards, wherein the one or more network standards include the first network standard and / or one or more network standards of other types besides the first network standard.

[0126] Step 304: The first RAN node receives the second information sent by the terminal.

[0127] Step 305: The first RAN node sends the second information to the target core network element so that the target core network element can register one or more network standards based on the second information.

[0128] In this embodiment of the application, the target core network element includes one or more core network elements, and the one or more core network elements correspond to the one or more network standards; wherein, when the target core network element includes one core network element, the target core network element represents a core network element used for sharing by the one or more network standards.

[0129] It should be noted that the specific processing procedures for information transmission completed by the first RAN node and the terminal have been detailed above and will not be repeated here.

[0130] By adopting the technical solution of this application embodiment, since the first RAN node is located in a non-terrestrial network, and non-terrestrial networks such as satellite nodes have predictability, after receiving the registration request information sent by the terminal, the first RAN node uses its predictability to predict one or more network standards at once, thereby enabling the target core network element to perform collaborative registration of one or more network standards. This reduces the signaling overhead caused by multiple registrations and connection establishments through registration updates and node updates.

[0131] The present application will now be described in detail with reference to application examples.

[0132] To address the issue of significant signaling overhead in related technologies due to multiple registrations and connection establishments via registration updates and node updates, this application primarily targets non-terrestrial networks. Unlike terrestrial networks, non-terrestrial networks, such as satellite nodes, possess predictability. This application leverages the predictability of non-terrestrial networks to design a multi-network standard collaborative registration (including pre-registration) mechanism. Multi-network standard collaborative registration is achieved through a single RAN node (corresponding to the aforementioned first RAN node), thereby reducing the signaling overhead of multiple registrations and connection establishments caused by registration updates and node updates. Therefore, this solution is geared towards 6G or future communications. For different standards, a multi-standard, multi-registration mechanism can be considered without distinguishing between primary and secondary nodes. The UE establishes connections and performs registrations with RAN and core networks of different standards, maintaining connections across multiple network standards and reducing the overhead of switching between different standards.

[0133] In the multi-network standard collaborative registration method proposed in this application, the NTN 5G / 6G base station (corresponding to 5G RAN node / 6G RAN node) and the TN 5G / 6G base station are connected to the same or different core networks. If they are connected to the same core network, the core network supports both 5G and 6G functions. If they are connected to different core networks, the 5G base station is connected to the 5GC and the 6G base station is connected to the 6GC. The terminal can connect to both the 5G RAN node and the 6G RAN node at the same time, and there is a (sequence) association between the 5G RAN node and the 6G RAN node. The terminal maintains multiple sets of RRC states.

[0134] For NTN-only scenarios (i.e., RAN nodes of different standards are all in NTN), Figure 4A This is a schematic diagram illustrating the multi-network standard collaborative registration interaction when the target core network element is multiple core network elements in the NTN only scenario of this application embodiment. Figure 4AAs shown, the UE simultaneously accesses both the 5G RAN node and the 6G RAN node. Both the 5G RAN node and the 6G RAN node are located within the NTN. The 5G RAN node and the 6G RAN node can exchange NTN RAN auxiliary information (corresponding to the first information mentioned above). The 5G RAN node and the 6G RAN node access different core network elements respectively. Specifically, the 5G RAN node accesses the 5GC, and the 6G RAN node accesses the 6GC. Furthermore, the 5GC and the 6GC exchange registration information of different standards. The UE establishes a registration path with the 5GC and the 6GC through an NTN RAN node of one standard, namely the 5G RAN node, thereby achieving collaborative registration of multiple standards.

[0135] Figure 4B This is a schematic diagram illustrating the multi-network standard collaborative registration interaction when the target core network element is of one type in the NTN-only scenario of this application embodiment. Figure 4B As shown, the UE simultaneously accesses both the 5G RAN node and the 6G RAN node. Both the 5G RAN node and the 6G RAN node are located within the NTN. The 5G RAN node and the 6G RAN node can exchange NTN RAN auxiliary information (corresponding to the first information mentioned above). Both the 5G RAN node and the 6G RAN node are connected to the same core network element (e.g., e5GC). The UE establishes a registration path with the e5GC through an NTN RAN node of one standard, namely the 5G RAN node, thereby achieving collaborative registration of multiple standards.

[0136] Here, NTN RAN nodes of different standards, such as 5G RAN nodes and 6G RAN nodes, can obtain each other's NTN RAN auxiliary information through the base station inter-interface and broadcast the NTN RAN auxiliary information to the terminal in the system information. The NTN RAN auxiliary information includes at least one of the following: ephemeris information (list), network standard type information (e.g., 5G or 6G network), time information (i.e., service time information of each satellite, corresponding to the aforementioned satellite service time information), orbit information (corresponding to the aforementioned satellite orbit information), TA pre-compensation parameter information, and network connection activation / deactivation indication information (used respectively for activating RAN / CN connections with valid service and deactivating RAN / CN connections with invalid service).

[0137] In this application, the terminal performs collaborative registration for multiple standards through an NTN RAN node of one standard (e.g., a 5G RAN node). The specific implementation process includes the following steps:

[0138] Step 0: Cell search, determine the cells that can be searched and read, and read system information.

[0139] Here, based on the Reference Signal Receiving Power (RSRP) / Reference Signal Receiving Quality (RSRQ) and / or the reference point information and / or the satellite service time information carried in the system information, one or more non-terrestrial network cells that can provide services (corresponding to the aforementioned target cell), the standard information of different cells (corresponding to the aforementioned target cell's network standard information), and the connection activation information, etc., are determined.

[0140] Step I: The terminal sends a command to RAN node 1 of system 1 (corresponding to the first RAN node mentioned above, for example...). Figure 4A , Figure 4B The 5GRAN node in the network sends a registration request message (corresponding to the second information mentioned above), and the registration request message carries one or more of the following auxiliary information:

[0141] Auxiliary information for the first network standard (e.g., standard 1) includes, for example, a candidate cell / RAN node list under standard 1 (i.e., the first RAN node list information), the corresponding priority attributes (which can be determined based on the distance between the terminal and the satellite cell reference point and the length of the satellite's service time), the corresponding frequency point information, and the service time information.

[0142] Auxiliary information for one or more other types of network standards (e.g., standard 2…n), such as standard information for standard 2…n, candidate cell / RAN node list under standard 2…n (i.e., one or more RAN node list information of other types), corresponding priority attributes, corresponding frequency information, and service time information.

[0143] New UE capability information, such as the types of network standards supported by the terminal and the number of connections to different network standards that can be maintained simultaneously.

[0144] Step 2a (corresponding to) Figure 4A (Different standards correspond to different core networks): If the registration request information contains auxiliary information for standard 1, then the RAN node 1 of standard 1 (e.g., 5G RAN node) sends the registration request information to the core network element 1 of standard 1 (corresponding to the aforementioned first core network element, e.g., 5GC). The core network element 1 of standard 1 creates UE context information for the UE and sends back the registration acceptance information for requesting to register for standard 1 to the UE (corresponding to the aforementioned third information).

[0145] If the registration request information contains auxiliary information for other standards (e.g., auxiliary information for standards 2…n) from step 1, the following process is executed: First, core network element 1 of standard 1 (e.g., 5GC) forwards the registration request information to core network elements of other standards (e.g., 6GC); then, the core network elements of other standards (e.g., 6GC) also create a corresponding set of UE context information for the UE and provide feedback to the terminal through one or more of the following methods:

[0146] Method 1: Send registration acceptance information (corresponding to the fourth information mentioned above) to the UE individually through RAN nodes of different types;

[0147] Method 2: The core network element of other standards (e.g., 6GC) forwards the created UE context information to the core network element 1 of standard 1 (e.g., 5GC). The core network element 1 of standard 1 (e.g., 5GC) then feeds back the fourth information to the terminal through the RAN node 1 of standard 1 (e.g., 5GRAN node). The fourth information includes the registration acceptance information for requesting registration of other standards and the RAN node information corresponding to other standards.

[0148] Step 2b (corresponding) Figure 4B Different standards correspond to one core network, i.e., the core network is a multi-standard shared core network: RAN node 1 of standard 1 (e.g., 5G RAN node) sends registration request information to the multi-standard shared core network element. If the registration request information contains auxiliary information for standard 1 and auxiliary information for other standards (e.g., auxiliary information for standard 2...n), the multi-standard shared core network element creates corresponding UE contexts for the UE for each standard and feeds back registration acceptance information to the UE through one or more of the following methods:

[0149] Method 1: Different types of RAN nodes send their respective registration acceptance information back to the UE.

[0150] Method 2: The RAN node 1 of the standard type sends multi-standard registration acceptance information to the UE, which includes the standard information of the multi-standard type and / or the corresponding RAN node information.

[0151] Figure 5 This is a schematic diagram illustrating the method flow for registering multiple core networks using a single RAN node in an NTN-only scenario according to an embodiment of this application. Figure 5 As shown, the method includes the following steps:

[0152] First, the UE sends a registration request to the 5G RAN node. This registration request includes NTN assistance information, and depending on the type of NTN assistance information, it selects to perform the following steps:

[0153] 1) If the NTN auxiliary information only includes 5G auxiliary information, the 5G RAN node will send the registration request to the 5GC network element. The 5GC network element will create UE context information for the UE and send the registration acceptance information for 5G registration back to the UE through the 5G RAN node.

[0154] 2) If the NTN auxiliary information only includes 6G auxiliary information, the 5G RAN node first sends a registration request to the 5GC network element, which then forwards the registration request to the 6GC network element. The 6GC network element creates UE context information for the UE and sends registration acceptance information for 6G registration back to the UE. This feedback can be achieved through one or more of the following methods:

[0155] 2-1) The 6GC network element sends a separate registration acceptance message to the UE through the 6G RAN node, requesting registration for 6G.

[0156] 2-2) The 6GC network element forwards the registration acceptance information to the 5GC network element. This registration acceptance information includes the registration information requesting 6G registration (other RAT Registration information) and 6G RAN node information (RAN information). The 5GC network element then feeds back the registration acceptance information to the UE through the 5G RAN node.

[0157] Figure 6 This is a schematic diagram illustrating the method flow for implementing multi-standard registration of a shared core network through a single standard RAN node in the NTN on1y scenario according to an embodiment of this application. Figure 6 As shown, the method includes the following steps:

[0158] First, the UE sends a registration request to the 5G RAN node. This registration request includes NTN assistance information, which includes assistance information for both 5G and 6G. Then, the 5G RAN node sends a registration request to the shared core network element. The shared core network element creates corresponding UE context information for the UE for both 5G and 6G, and can provide feedback through one or more of the following methods:

[0159] In Method 1, the shared core network elements send 5G registration acceptance information to the UE through the 5G RAN node and 6G registration acceptance information to the UE through the 6G RAN node.

[0160] Method 2: Shared core network elements feed back registration acceptance information for multiple standards to the UE through the 5G RAN node (registration acceptance information for 5G and 6G registration requests), which includes multiple standard information and / or corresponding RAN node information.

[0161] Unlike TN-only multi-standard registration, based on the above registration process, multiple standards can be registered at once in an NTN-only scenario due to the predictability of satellites. The terminal and network side can then activate the corresponding network connections at different times based on NTN auxiliary information (i.e., the auxiliary information in Step 1), saving the signaling overhead of traditional registration updates and connection establishment. Furthermore, after the multi-network standard connection is established, different service types are provided to the terminal on different network bearers. If a certain network standard connection is lost, services can be seamlessly obtained through other network standards, reducing handover overhead.

[0162] Here, the specific method for activating the corresponding network connection at different times is as follows: The terminal uses the corresponding RAN and core network connection during the corresponding service time according to the service time information in the auxiliary information provided by the network side.

[0163] If the service time information is a specific execution time point (corresponding to the aforementioned start service time point information), then the corresponding RAN and core network connection becomes effective at that time point, and the terminal and network side automatically align their information. If the service time information is a time period (corresponding to the aforementioned service time period information) or a service termination time point (corresponding to the aforementioned service termination time point information, before which the network side can provide a valid connection, that is, the terminal can send and receive data at any time before that time point), then after the terminal and the corresponding RAN and core network connection become available, the terminal sends an uplink message (corresponding to the aforementioned sixth information). This uplink message can be a TA report, a preamble message, or an initiation of a random access procedure to align the terminal and network side's information.

[0164] For NTN-TN scenarios (i.e., RAN nodes of different standards are located in NTN and TN respectively), Figure 7A This is a schematic diagram illustrating the multi-network standard collaborative registration interaction when the target core network element is multiple core network elements in the NTN-TN scenario of this application embodiment. Figure 7AAs shown, the UE simultaneously accesses both the 5G RAN node and the 6G RAN node. The 5G RAN node is located in the NTN, while the 6G RAN node is located in the TN. The 5G RAN node can send NTN RAN auxiliary information to the 6G RAN node. The 5G RAN node and the 6G RAN node access different core network elements, with the 5G RAN node accessing the 5GC and the 6G RAN node accessing the 6GC. The 5GC and 6GC exchange registration information for different standards. The UE establishes a registration path with the 5GC and 6GC through the 6G RAN node, thereby achieving collaborative registration for multiple standards.

[0165] Figure 7B This is a schematic diagram illustrating the multi-network standard collaborative registration interaction when the target core network element is a single core network element in the NTN-TN scenario of this application embodiment. Figure 7B As shown, the UE simultaneously accesses both the 5G RAN node and the 6G RAN node. The 5G RAN node is located in the NTN, while the 6G RAN node is located in the TN. The 5G RAN node can send NTN RAN auxiliary information to the 6G RAN node. Both the 5G RAN node and the 6G RAN node are connected to the same core network element (e.g., e5GC). The UE establishes a registration path with the e5GC through the 6G RAN node, thereby achieving collaborative registration for multiple standards.

[0166] For NTN-TN scenarios, the above mechanism can also be used for collaborative registration of multiple network standards. Unlike the NTNonly scenario, if the registration request is made through the TN RAN node, the NTN auxiliary information can be sent from the NTN RAN node of standard 2 to the TN RAN node of standard 1 through the inter-base station interface. Registration cannot be achieved on the TN side (the TN network is not predictable). The TN RAN node can assist the NTN RAN node in completing the registration.

[0167] In practical applications, considering cross-carrier scenarios, unlike existing roaming mechanisms, users can only switch to other carriers' service networks when their current carrier does not provide coverage. Users can independently activate a network connection to the carrier providing the corresponding service (corresponding to the aforementioned target network connection) based on their business needs (e.g., wanting to access services provided by other carriers). Alternatively, a threshold-based carrier service network connection switching can be introduced, such as based on network speed. If the current network speed is below a certain threshold, the terminal will choose to communicate with other registered carrier networks.

[0168] Compared with related technologies, the solution presented in this application has the following advantages: This application leverages the predictability of non-terrestrial networks to design a multi-network standard collaborative registration mechanism, thereby reducing the signaling overhead of multiple registrations and connection establishments caused by registration updates and node updates. This solution features enhanced design for NTN 5G and 6G collaboration and has strong commercial application prospects.
