Description

Technical Field

[0001] The present application relates to a wireless communication network, for example, to a network information reporting method, device, user terminal, service node and medium. Background Art

[0002] Fifth Generation (5G) New Radio (NR) is widely used in terrestrial communication networks, including enhanced mobile broadband (eMBB), massive machine-type communications (m-MTC), etc. Based on terrestrial communication networks, NR technology can be extended to non-terrestrial communication networks. In non-terrestrial communication networks, part or all of the functions of base stations will be deployed in satellites or aerial vehicles. Therefore, the cell coverage area of ​​non-terrestrial communication networks is much larger than that of terrestrial communication networks. For example, the coverage range of a beam of a low-orbit satellite can reach 100-500km, resulting in a cell of a non-terrestrial communication network covering multiple regions or countries, or even covering tens of thousands of cells of terrestrial communication networks. Different regions or countries usually have different charging policies and information control methods, and provide different services for user equipment (UE). Therefore, when the user terminal works in a cell of a non-terrestrial communication network with a wide coverage area, the service node cannot know in which region or country the user terminal is located, and cannot provide corresponding effective services to the user terminal according to the policies of different regions or countries, and may even cause service abnormalities or interruptions.

[0076] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0077] A cell of a first-type network with a wide coverage area covers multiple regions or countries, and the charging policies, information control and service types of different regions or countries are different. In the related art, when a user terminal works in a cell of the first-type network, the service node of the first-type network cannot know which region or country the user terminal is located in, resulting in the service node being unable to provide targeted services to the user terminal.

[0078] In a cell of a first type network with a wide coverage, there is usually at least one cell of a second type network with a smaller coverage. This embodiment aims at the problem that the first type network has a wide coverage and cannot identify the region or country where the user terminal is located. By having the user terminal report the network information of the target cell of the second type network with a smaller coverage to the service node, the target cell of the second type network where the user terminal is located can be accurately identified in the first type network, thereby accurately identifying the region or country where the user terminal is located, so that the service node can provide effective services to the user terminal according to different regions or countries.

[0079] This embodiment provides a network information reporting method, which is applied to UE. Figure 1 FIG. 1 is a flow chart of a network information reporting method provided by an embodiment. Figure 1 As shown, the method provided in this embodiment includes step S110 and step S120.

[0080] Step S10: When the user terminal operates in the first type of network, detect a cell of the second type of network.

[0081] In one embodiment, the UE working in the first type of network means that the UE resides in the first type of network or the UE establishes a Radio Resource Control (RRC) connection with the first type of network. Detecting a cell of the second type of network means that the UE performs cell selection or cell reselection for a cell of the second type of network, and uses the cell of the second type of network obtained by the cell selection or cell reselection as the target cell of the detected second type of network. The user terminal obtains the network information of the target cell from the broadcast message of the target cell, and reports it to the service node of the first type of network as the cell network information. Cell selection and reselection comply with the rules of cell selection or reselection in the existing relevant protocols.

[0082] Step S20: Reporting cell network information to a service node of the first type of network, wherein the cell network information includes network information corresponding to a detected target cell of the second type of network.

[0083] In one embodiment, the first type of network is a non-terrestrial network (NTN), and the second type of network is a terrestrial network (TN).

[0084] In one embodiment, the cell network information includes at least one of a public land mobile network (PLMN) identifier, a tracking area identifier (TAI), a cell global identifier (CGI) and a radio access node area code (RAN-AreaCode).

[0085] In one embodiment, the UE may detect a cell of the second type network in any of the following situations: when the UE registers in the first type network; when the UE determines that the cell network information needs to be updated; when the UE establishes an RRC connection in the first type network; when the UE restores the RRC connection in the first type network; when the UE performs switching or synchronous reconfiguration in the first type network; when the UE performs RRC connection reconstruction in the first type network; and when the UE performs location information reporting in the first type network.

[0086] In one embodiment, the UE may report the cell network information to the service node of the first type of network through at least one of the following messages: RRC connection establishment completion message; RRC connection recovery completion message; uplink information transmission message; RRC connection reconfiguration completion message; RRC connection reconstruction completion message; RRC auxiliary information message; RRC message newly added for reporting the second type of network information.

[0087] In one embodiment, the UE directly includes the cell network information in any one of the above messages and reports it to the service node, or includes the cell network information in a non-access stratum (NAS) message, and then includes the NAS message in any one of the above messages and reports it to the service node. When the service node receives the cell network information reported by the UE, it sends the cell network information to the core network, and the core network makes a decision based on the cell network information, thereby providing effective services for the UE.

[0088] In one embodiment, the UE is in an idle state (RRC_IDLE), and reports cell network information to a service node of a first type of network, including: when the user terminal is registered in the first type of network, or when the cell network information is in a state to be updated, sending a registration request to the service node of the first type of network, and reporting the cell network information through the registration request.

[0089] Figure 2A flowchart for implementing reporting of cell network information provided by an embodiment. In this embodiment, the UE is in an idle state (RRC_IDLE). When the user terminal is registered in the first type of network, or when the cell network information is in a pending update state, or when the user terminal initiates RRC connection establishment in the first type of network, the UE sends a registration request to the service node of the first type of network, and reports the cell network information through the registration request. Figure 2 As shown, reporting the cell network information to the service node of the first type of network includes steps S1110 to S1130.

[0090] Step S1110: Send an RRC connection establishment request (RRCSetupRequest) to the service node of the first type of network.

[0091] Step S1120: Receive an RRC connection establishment message (RRCSetup) fed back by a service node of the first type of network.

[0092] Step S1130: Send an RRC connection setup complete message (RRCSetup Complete) to the service node of the first type of network, wherein the connection setup complete message includes a NAS message, and the NAS message includes cell network information. The NAS message may be a registration request (Registration Request).

[0093] In one embodiment, when the service node receives the RRC connection establishment completion message sent by the UE, the service node sends an initial UE message (Initial UE Message) to the core network, where the initial UE message includes a NAS message, and the NAS message includes cell network information.

[0094] In one embodiment, the RRC connection establishment completion message includes the cell network information, and the cell network information is directly reported to the service node through the RRC connection establishment completion message. The service node sends an initial UE message to the core network, and the initial UE message includes the cell network information.

[0095] In one embodiment, before sending a registration request to a service node of a first type of network, it also includes: obtaining a first system message of a target cell of the second type of network, the first system message including at least one of a public land mobile network identifier, a tracking area identifier, a cell global identifier, and a radio access network area code; determining that the cell network information is in a state to be updated according to the first system message. In this embodiment, the UE obtains the first system message from the target cell of cell selection or cell reselection, and determines whether the cell network information is in a state to be updated according to the obtained first system message. The UE can determine whether the PLMN, TAI, CGI, or RAN-Area Code of the target cell has changed compared to the historical target cell according to the first system message, and determine that the cell network information is in a state to be updated when at least one of the PLMN, TAI, CGI, and RAN-Area Code has changed.

[0096] Figure 3 FIG. 1 is a flowchart of an implementation of reporting cell network information provided by an embodiment. In this implementation, the service node feeds back an information reporting request to the user terminal after receiving the first indication information.

[0101] S1250. Send the cell network information to a service node of the first type of network according to the information reporting request.

[0102] In one embodiment, upon receiving the cell network information reported by the UE, the service node sends a location report message (Location Report) to the core network, where the location report message includes the cell network information.

[0103] In one embodiment, before the UE receives the information reporting request for the first indication information feedback from the service node of the first type of network, the method further includes: receiving security configuration information of the service node. After sending the security configuration information, the service node sends an information reporting request to the UE to ensure the security of cell network information transmission.

[0104] Figure 4 The present invention provides a flowchart for implementing a method of reporting cell network information provided by an embodiment. In this embodiment, the UE is in an inactive state (RRC_INACTIVE), and the UE resides in a first type of network.

The cell network information may be included in the UE location information (User Location Information) of the RRC Inactive Transition Report message. The RRC Inactive Transition Report message is used to notify the core network that the UE has entered or left the RRC_INACTIVE state, wherein entering or leaving the RRC_INACTIVE state depends on the network implementation.

[0114] Figure 6 A flowchart for implementing reporting of cell network information provided by an embodiment. In this embodiment, the UE is in a connected state (RRC_CONNECTED). When the cell network information is in a state to be updated, the UE sends a registration request to a service node of a first type of network, and reports the cell network information through the registration request. The state to be updated of the cell network information means that when the UE makes a cell selection or a cell reselection in the second type of network, it obtains a system message from the selected target cell, and determines the need to update the cell network information based on the obtained system message. Figure 6 As shown, reporting cell network information to a service node of the first type of network includes step S3100.

[0182] In this embodiment, when the UE resides in the first type of network, network configuration information sent by the service node is received, and the network configuration information includes frequency configuration information. The UE reports cell network information of at least one target cell on at least one target frequency to the service node, thereby solving the problem that different targeted services and controls cannot be provided to user terminals according to different national boundaries or geographical locations due to the wide deployment range of the first type of network.

[0183] Fig.14 The following is a flowchart of an implementation of reporting cell network information provided by an embodiment. In this embodiment, the UE is in the RRC_CONNECTED state, and the UE receives network configuration information from the RRC connection reconfiguration message, and the network configuration information includes frequency configuration information and time configuration information.

[0187] In this embodiment, the UE receives network configuration information from an RRC connection reconfiguration message. The network configuration information includes configuration information of at least one target frequency and indication information for reporting cell network information. The indication information for reporting cell network information is configured separately for each target frequency, or it can be configured uniformly for all target frequencies configured by the frequency configuration information. The UE is in the RRC_CONNECTED state, and the UE has established an RRC connection with a first type of network (such as an NTN network), and the at least one target frequency is a frequency used by a second type of network (such as a TN network). When the UE receives the network configuration information, it measures at least one configured target frequency according to the network configuration information. When at least one target cell on the at least one target frequency is measured, the UE reads the system message of at least one target cell to obtain the cell network information.

[0188] In one embodiment, when the service node receives the measurement report reported by the UE, the service node sends a location report message to the core network, where the location report message includes cell network information of at least one target cell reported by the UE.

[0189] In one embodiment, the network configuration information may be included in the measurement configuration of the RRC connection reconfiguration message.

In the case of a periodic trigger type, the network configuration information also includes time configuration information. The time configuration information is timer configuration information or time interval configuration information.

[0190] In one embodiment, the UE triggers a measurement report according to an event trigger type or a periodic trigger type in a related system (such as 4G, 5G), and reports the measurement report to the service node when the measurement report is triggered.

[0191] In this embodiment, when the UE works in the first type of network, the UE receives network configuration information sent by the service node, and the network configuration information includes frequency configuration information configured for the second type of network. The UE reports the cell network information of at least one target cell on at least one target frequency to the service node, which solves the problem that different services and controls cannot be provided to user terminals according to different national boundaries or geographical locations due to the wide deployment range of the first type of network, and realizes the correct identification of the cell of the second type of network under the coverage of the first type of network.

[0192] Fig.15 A schematic diagram of the deployment of a first type of network and a second type of network is provided for an embodiment. In one embodiment, the first type of network is an NTN network, and the second type of network is a TN network. The coverage of an NTN cell is very wide, and the coverage of an NTN cell includes many TN cells. During the deployment of a TN network, due to the limited PCI (Physical Cell Identity, PCI), for example, in a 5G NR (New Radio) network, the maximum PCI value is 1008. Therefore, when operators deploy a TN network, for physical cells on the same frequency, PCI duplication is usually not allowed within a certain area, and PCI duplication is allowed only when it exceeds a certain area. Fig.15 In the NTN cell coverage shown, cell X and cell Y are far apart, so they are allocated to use the same frequency and PCI. The method of this embodiment is used to correctly identify cell X and cell Y.

The UE determines when it is necessary to report the measurement report according to the measurement event configured by the network side, and the event can be an A series event (including A1 / A2 / A3 / A4 / A5 / A6, etc.) or a B series event (including B1 / B2, etc.).

The UE reports the auxiliary information in any of the above ways.

[0201] In one embodiment, during the process of UE reporting auxiliary information, when a measurement report is triggered, if the UE has valid auxiliary information, it will be reported; if the current UE does not have valid auxiliary information, the auxiliary information may not be carried.

[0313] The embodiment of the present application also provides a dual connection method. Fig. 22 FIG. 5 is a schematic diagram of a 5G network architecture provided by an embodiment. Fig. 22As shown: 5G radio access network (Fifth Generation Radio Access Network, NG-RAN) base stations are interconnected with 5G core network (Fifth Generation Core, 5GC) through NG interface, specifically including control plane (Next Generation-Control Plane, NG-C) connection between 5G core network and NG-RAN base station and user plane (Next Generation-User Plane, NG-U) connection between 5G core network and NG-RAN base station, while NG-RAN base stations are interconnected through Xn interface between NG-RAN base stations, specifically including control plane (Xn-Control Plane, Xn-C) connection between NG-RAN base stations and user plane (Xn-User Plane, Xn-U) connection between NG-RAN base stations. NG-RAN base stations include at least one of next generation base station (nextGeneration Node B, gNB) and next generation evolved base station (Fifth Generation-evolved Node B, ng-eNB). 5GC includes at least one of Access Mobility Function (AMF), Session Management Function (SMF) and User Plane Function (UPF). The control plane connection of the above interface is used to transmit control signaling messages between network element nodes; and the user plane connection is used to transmit user service data. The NG-RAN base station and the served terminal UE are connected to each other through the wireless air interface (i.e., Uu air interface), including the air interface control plane signaling radio bearer (SRB) and the air interface user plane data radio bearer (DRB).

[0314] The 5G system supports the dual / multiple connectivity (DC / MC) working mode of the terminal UE (this embodiment is illustrated using dual connection DC as an example). Fig.23 FIG. 1 is a schematic diagram of a dual connection operation controlled by a master base station according to an embodiment. In a dual / multiple connection working mode, Fig.23As shown, in a specific physical area, the master node (MasterNode, MN) is usually used to provide wireless macro coverage, while in local hotspot areas, the secondary node (Secondary Node, SN) is used to provide capacity enhancement. When the UE is in the overlapping coverage area of ​​the MN main service cell and the SN secondary service cell, under the control of the master base station MN, there will be NG-C and NG-U interface connections between MN and 5GC, and there will be Xn-C and Xn-U interface connections between MN and SN, but there is only NG-U connection between SN and 5GC. Therefore, the UE's entry, exit, and related operations in the dual-connection working mode are all completed by the master control of the master base station MN. The currently supported dual / multi-connection operations must rely on the Xn-C interface between MN and SN to complete the relevant control of MN to SN, as well as the coordination of resource configuration and update of working status between each other.

[0315] In traditional land-based cellular mobile systems, once the deployment of a base station is completed, its geographical location is fixed, so the wireless coverage (Coverage) / capacity (Capacity) of the air interface Uu serving cell (Serving Cell) it provides, as well as its Xn interface instance connected to the adjacent base station, are also fixed. In recent years, with the emergence of various types of mobile base stations or network element nodes, such as ground vehicle-mounted mobile base stations, aerial drone base stations, satellite base stations, etc., the wireless coverage / capacity supply of the air interface serving cells provided by these mobile base stations usually changes continuously with the movement of the physical location of the mobile base stations, and the bearer transmission of the NG, Xn and other interfaces connecting these mobile base stations can no longer be the traditional fixed network transmission method, that is, it cannot be carried and transmitted through fixed network methods such as broadband optical fiber, and usually can only rely on wireless bearer methods, such as microwave, laser and other relay technology means. Although this cellular mobile network built by mobile base stations is more flexible in deployment (no fixed site resources are required), the bearer transmission between network element nodes can only be planned and managed in a relatively dynamic manner; otherwise, as the network element nodes move, the network topology or environmental conditions will continue to change, the original old network element interface connection and configuration may become invalid, and the new network element interface connection and configuration need to be established and maintained.

[0316] Fig.24 FIG. 1 is a schematic diagram of a satellite base station service cell coverage change according to an embodiment. Fig.24As shown in the figure: there are several space-based satellite base stations (mobile nodes 1 / 2 / 3 / 4), etc., each of which provides a satellite service beam (Beam) from the air to a specific coverage area on the ground, forming the coverage of ground service cells 1 / 2 / 3 / 4, etc., but as these satellite base stations move to the left along the track, the coverage of ground service cells 1 / 2 / 3 / 4, etc., etc., provided by them, will also move to the left along with the satellite base station; assuming that there is also a main base station MN on the ground providing coverage of service cell A, then the relative position relationship between the cell coverage provided by the satellite base station and the cell coverage provided by the ground MN base station will change dynamically. Therefore, a relatively stable Xn interface connection may not be established between the satellite base station and the terrestrial base station, on the one hand because they need a wireless connection, and on the other hand if an Xn interface connection is established between them, the Xn interface connection needs to be deleted, established, deleted or established continuously.

[0317] The wireless link between the terminal UE and the satellite base station is usually called the service link. It is oriented to the served UE and directly carries the user service data and RRC signaling on the 5G NR Uu air interface. From the UE's perspective, even if it is stationary, its service link will change accordingly as the satellite base station continues to move.

[0318] Fig.25 FIG. 1 is a schematic diagram of establishing and maintaining a satellite base station feeder link according to an embodiment. Fig.25 As shown, the wireless link between the satellite base station and the ground station is usually called a feeder link. The feeder link needs to provide at least the transmission function between the satellite base station and the core network 5GC. In one embodiment, the ground station can be a non-terrestrial network gateway (NTN-GW), that is, a network element node of the core network. If the satellite base station is a complete gNB, then the feeder link at this time needs to provide stable transmission services for the NG interface, that is, reliably transmit control signaling and user service data. Although satellite base stations are always moving at high speeds, it is usually assumed that the feeder link between them and the NTN-GW is robust enough, so a relatively stable NG interface connection instance can be established. Through multiple NTN-GW transmission layer routing multi-hops and relays on the ground, there is no need to frequently update and maintain the NG interface instance. For example, the attached Fig.25In the figure, when the satellite base station mobile node 1 (Moving Node1) gradually moves to the left from the jurisdiction of ground station 2 to the jurisdiction of ground station 3, through the ground transmission relay between ground stations 2 and 3, the NG interface instance between the satellite base station and the core network anchor network element can be assumed to remain unchanged, without deleting the old NG interface connection and rebuilding a new NG interface connection.

[0319] Combining the characteristics of the above-mentioned traditional dual-connection operation of the terminal UE (the physical location of the primary and secondary base stations is fixed, the Xn interface connection is fixed and relatively robust, and the MN is the master), and the characteristics of the deployment of mobile base stations represented by satellite base stations (satellite base stations move along the track regularly and periodically, the Xn interface connection is not fixed and the robustness is relatively low), if in the future, the terminal UE also needs to perform dual / multi-connection operations between the ground fixed base station and the mobile satellite base station, since it can no longer rely on the Xn interface between the primary and secondary base stations, it can only rely on the relatively more stable NG interface. How to obtain UE DC related information (especially when the dual connection in TN / NTN networking only relies on the NG interface) is also a problem that needs to be solved.

[0320] Fig.26 A schematic diagram of an architecture diagram of a 5GC master UE performing dual connection operations provided by an embodiment. Fig.26 As shown in the figure, the overall wireless capabilities and resources of the UE can be divided into two relatively independent parts, namely the wireless capabilities and resources applicable to the MN (i.e., UE-MN in the figure) and the wireless capabilities and resources applicable to the SN (i.e., UE-SN in the figure). The UE DC information reflects the wireless capabilities and resources applicable to the MN and the wireless capabilities and resources applicable to the SN when the UE performs DC operation.

[0321] The UE DC information is sent by the UE to the gNB via a UE Capability Information message or a UE Assistance Information message.

[0322] The UE Capability Information message carrying the UE DC information is sent when the UE receives a UE Capability Enquiry message from the gNB indicating a request to report the UE DC information.

[0323] The UE Assistance Information message carrying the UE DC information is sent when the UE receives an RRC reconfiguration message from the gNB indicating a requirement to report the UE DC information, or when the UE has not sent the UE DC information to the gNB or the UE DC information is updated.

[0324] The UE DC information is sent by the gNB to the 5GC via a UE radio capability indication (Radio Capability Info Indication) message or a UE DC information acquisition response message.

[0325] The UE Radio Capability Info Indication message carrying the UE DC information is sent when the gNB determines that it is necessary, or when the gNB receives a UE DC information acquisition request message from the 5GC. The UE Radio Capability Info Indication message is sent when the gNB determines that it is necessary, including when the initial connection establishment request (Initial Context Setup Request) message does not carry the UE DC information, or when the gNB has not sent the UE DC information to the 5GC, or when the UE DC information is updated.

[0326] The UE DC0 information acquisition response message carrying the UE DC information is sent when the gNB receives the UE DC information acquisition request message from the 5GC.

[0327] For connected UEs, 5GC sends a UE DC information acquisition request message to gNB when it is determined to be necessary (for example, 5GC does not have relevant UE DC information, or 5GC suspects that the relevant UE DC information is not up to date).

[0328] For connected UEs, the gNB sends a UECapability Enquiry message to the UE to request reporting of UE DC information if it determines that it is necessary (for example, the gNB does not have relevant UE DC information, or the gNB determines that the relevant UE DC information is not the latest).

[0329] For connected UEs, the gNB sends an RRC Reconfiguration message to the UE to indicate the request to report UE DC information if it determines it is necessary (for example, the gNB is set to always obtain the latest relevant UE DC information in a timely manner).

[0330] The UE DC information includes: one or more groups of information, wherein each group of information includes at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, service quality of service (QoS) capability supported by the MN side, QoS capability supported by the SN side, capability and resource ratio (percentage) supported by the MN side, capability and resource ratio (percentage) supported by the SN side, DRB ID space available on the MN side, DRB ID space available on the SN side, logical channel (Logical Channel) identifier (ID) space available on the MN side, Logical Channel ID space available on the SN side, band combination (Band Combination) information available on the MN side, band combination information available on the SN side, and an index number of the group information.

[0331] The RAT type supported by the MN side and the RAT type supported by the SN side include one of the following: NR, Evolved-UMTS Terrestrial Radio Access (EUTRA), New Radio Low Earth Orbit (NR LEO), New Radio Middle Earth Orbit (NRMEO), New Radio Geostationary Earth Orbit (NR GEO), NR Satellite, NR Non-terrestrial and Non-3GPP InterWorking Function (N3IWF). In one embodiment, N3IWF is, for example, a Wireless Local Area Network (WLAN).

[0332] The QoS capabilities supported by the MN side and the QoS capabilities supported by the SN side include at least one of the following: supported 5G QoS identifier (5G Quality of Service Identifier, 5QI), supported packet delay budget PDB (Packet DelayBudget), whether to support delay critical services, supported uplink and downlink maximum flow bit rates (Maximum Flow Bit Rate), supported uplink and downlink maximum data radio bearer bit rates (Maximum DRBBit Rate), and supported uplink and downlink maximum UE bit rates (Maximum UE Bit Rate).

[0334] The available Logical Channel ID space on the MN side and the available Logical Channel ID space on the SN side include one of the following: the starting value and the ending value of the available Logical Channel ID, the number of available Logical Channel IDs, a list of available Logical Channel ID values, and the available Logical Channel ID values ​​represented by a bit string.

[0335] Fig. 27 A schematic diagram of dual connection operation for a gNB-type LEO satellite base station provided by an embodiment. Fig. 27 As shown in the figure, in a certain LEO low-orbit satellite communication system, several LEO low-orbit satellites are in a specific near-Earth orbit, according to the predetermined ephemeris information, and periodically orbit the Earth. They all carry complete gNB base station functions and provide satellite wireless access services for UE. Several satellite gateways NTN-GW are deployed on the ground, which are integrated in the 5GC core network. Each LEO satellite relies on its own positioning capability. According to the current latitude and longitude position, it can establish a Feeder link with one or more NTN-GWs on the ground in a timely manner to carry NG interface connection instances. Each LEO satellite projects beam coverage to a predetermined area on the ground (the large ellipse in the figure, usually with a coverage radius much larger than that of the terrestrial base station service cell). As the LEO satellite moves, these satellite beam coverages also slide on the ground, forming heterogeneous overlapping coverage with the terrestrial base station service cell coverage (the small ellipse in the figure).

[0336] Fig.28 The present invention is a flowchart of an implementation of a dual connection operation of a MN triggering the addition of a SN provided in an embodiment. In this embodiment, the method includes steps S9110 to S9150.

[0337] Step S9110. At time T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so that gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so it is possible to perform ground-to-air dual connection operation. A UE in the connected state is being served by the gNBx service cell, and a protocol data unit (PDU) session (PDUSession1 and PDU Session2) has been established, as well as radio resources related to user service data and NG interface connection transmission channels. According to the ephemeris information of the LEO low-orbit satellite system, gNBx (i.e., the master base station MN) can decide to add gNB1 as SN at the appropriate time.

[0338] Step S9120. MN sends a UE Capability Enquiry message to the UE to obtain UE DC information.

[0339] Step S9130. The UE sends a UE Capability Information message to the MN, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, available data radio bearer (DRB) ID space on the MN side, available DRB ID space on the SN side, and index number of the group information.

[0340] Step S9140. The MN determines, based on the UE DC information and local policies (such as security or billing, etc.), that the user service data of PDUSession1 can be carried and transmitted by the LEO satellite wireless link.

[0341] Step S9150.MN sends an SN addition request (Addition Required) message to 5GC1, which includes a request to divert the entire PDU Session1 currently carrying the service on the MN side to SN (gNB1).

[0342] Fig.29A flowchart for implementing a dual connection operation of adding a SN by triggering 5GC according to an embodiment. In this embodiment, the method includes steps S9210 to S9270.

[0343] Step S9210. At T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so it is possible to perform ground-to-air dual connection operation. A UE in the connected state is being served by the gNBx service cell, and the wireless resources and NG interface connection transmission channels related to the user service data of PDU Session1 and PDU Session2 have been established. According to the ephemeris information of the LEO low-orbit satellite system, 5GC1 can decide to add gNB1 as SN at the appropriate time, and gNBx is the main base station MN.

[0344] Step S9220.5GC1 sends a UE DC information acquisition request message to MN to obtain UE DC information.

[0345] Step S9230. MN sends a UE Capability Enquiry message to the UE to obtain UE DC information.

[0346] Step S9240. The UE sends a UE Capability Information message to the MN, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRBID space available on the MN side, DRB ID space available on the SN side, and the index number of the group information.

[0347] Step S9250. MN sends a UE DC information acquisition response message UE RadioCapability InfoIndication message to 5GC1, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRB ID space available on the MN side, DRB ID space available on the SN side, and index number of the group information.

[0349] Step S9270.5GC1 sends an SN Addition Required message to the SN, which includes a request to divert the entire PDU Session1 that is currently carrying the service on the MN side to the SN (gNB1).

[0350] Fig.30 The present invention is a flowchart of an implementation of a dual connection operation of a MN triggering the addition of a SN provided in an embodiment. In this embodiment, the method includes steps S9310 to S9350.

[0351] Step S9310. A UE in a connected state is being served by the service cell of gNBx. gNBx sends a UECapability Enquiry message to the UE to obtain UE DC information.

[0352] Step S9320. The UE sends a UE Capability Information message to gNBx, carrying UE DC information, including: one or more groups of information, where each group of information includes at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRBID space available on the MN side, DRB ID space available on the SN side, and index number of the group information.

[0353] Step S9330. At T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so that gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so that ground-to-air dual connection operation is possible. At this time, the UE has established the wireless resources and NG interface connection transmission channels related to the user service data of PDUSession1 and PDU Session2. According to the ephemeris information of the LEO low-orbit satellite system, gNBx (i.e. the main base station MN) can decide to add gNB1 as SN at the appropriate time.

[0354] Step S9340. The MN determines, based on the UE DC information and local policies (such as security or billing, etc.), that the user service data of PDUSession1 can be carried and transmitted by the LEO satellite wireless link.

[0355] Step S9350.MN sends an SN Addition Required message to 5GC1, which includes a request to divert the entire PDU Session1 currently carrying the service on the MN side to SN (gNB1).

[0356] Fig.31 A flowchart of the implementation of a dual connection operation of adding a SN by triggering 5GC according to an embodiment. In this embodiment, the method includes steps S9410 to S9460.

[0357] Step S9410. Fig.31 As shown: A UE in a connected state is being served by the serving cell of gNBx, and gNBx sends a UE Capability Enquiry message to the UE to obtain UE DC information.

[0358] Step S9420. The UE sends a UE Capability Information message to gNBx, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRBID space available on the MN side, DRB ID space available on the SN side, and the index number of the group information.

[0360] Step S9440. At T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so it is possible to perform ground-to-air dual connection operation. At this time, the UE has established the wireless resources and NG interface connection transmission channel related to the user service data of PDUSession1 and PDU Session2. According to the ephemeris information of the LEO low-orbit satellite system, 5GC1 can decide to add gNB1 as SN at the appropriate time, and gNBx is the main base station MN.

[0361] Step S9450.5GC1 determines, based on the UE DC information and local policies (such as security or billing, etc.), that the user service data of PDUSession1 can be carried and transmitted by the LEO satellite wireless link.

[0362] Step S9460.5GC1 sends an SN Addition REquest message to the SN, which includes a request to divert the entire PDU Session1 that is currently carrying the service on the MN side to the SN (gNB1).

[0363] Fig.32 The present invention is a flowchart of an implementation of a dual connection operation of a MN triggering the addition of a SN provided in an embodiment. In this embodiment, the method includes steps S9510 to S9550.

[0364] Step S9510. A UE in a connected state is being served by the serving cell of gNBx. gNBx sends an RRCReconfiguration message to the UE to obtain UE DC information.

[0365] Step S9520. When the UE has not sent UE DC information to gNBx or the UE DC information is updated, the UE sends a UE Assistance Information message to gNBx, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRB ID space available on the MN side, DRB ID space available on the SN side, and index number of the group information.

[0366] Step S9530. At T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so that gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so that ground-to-air dual connection operation is possible. At this time, the UE has established the wireless resources and NG interface connection transmission channels related to the user service data of PDUSession1 and PDU Session2. According to the ephemeris information of the LEO low-orbit satellite system, gNBx (i.e. the main base station MN) can decide to add gNB1 as SN at the appropriate time.

[0367] Step S9540. The MN determines, based on the UE DC information and local policies (such as security or billing, etc.), that the user service data of PDUSession1 can be carried and transmitted by the LEO satellite wireless link.

[0368] Step S9550.MN sends an SN Addition Required message to 5GC1, which includes a request to divert the entire PDU Session1 currently carrying the service on the MN side to SN (gNB1).

[0369] Fig.33 A flowchart of the implementation of a dual connection operation of adding a SN by triggering 5GC in an embodiment. In this embodiment, the method includes steps S9610 to S9660.

[0370] Step S9610. A UE in a connected state is being served by the serving cell of gNBx. gNBx sends an RRCReconfiguration message to the UE to obtain UE DC information.

[0371] Step S9620. When the UE has not sent UE DC information to gNBx or the UE DC information is updated, the UE sends a UE Assistance Information message to gNBx, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRB ID space available on the MN side, DRB ID space available on the SN side, and index number of the group information.

[0372] Step S9630.gNBx sends a UE Radio Capability Info Indication message to 5GC1, carrying UE DC information, including: one or more groups of information, each group of information including at least one of the following: RAT type supported by the MN side, RAT type supported by the SN side, QoS capability supported by the MN side, QoS capability supported by the SN side, capability ratio supported by the MN side, capability ratio supported by the SN side, DRB ID space available on the MN side, DRB ID space available on the SN side, and index number of the group information.

[0373] Step S9640. At T1, the satellite base station A (gNB1) anchor point is connected to NTN-GW / 5GC1, and the land base station gNBx is also connected to 5GC1. According to the network management configuration information, gNBx and 5GC1 both have the ephemeris information of the LEO low-orbit satellite system (i.e. which LEO satellite will run to which orbital position at what time, and the corresponding beam ground coverage is approximately in which area), so gNBx and 5GC1 can infer that: during a period of observation before and after T1, the ground coverage of the gNB1 beam and the coverage of the gNBx service cell have a certain overlap, so it is possible to perform ground-to-air dual connection operation. At this time, the UE has established the wireless resources and NG interface connection transmission channel related to the user service data of PDUSession1 and PDU Session2. According to the ephemeris information of the LEO low-orbit satellite system, 5GC1 can decide to add gNB1 as SN at the appropriate time, and gNBx is the main base station MN.

[0374] Step S9650.5GC1 determines, based on the UE DC information and local policies (such as security or billing, etc.), that the user service data of PDUSession1 can be carried and transmitted by the LEO satellite wireless link.

[0375] Step S9660.5GC1 sends an SN Addition Required message to the SN, which includes a request to divert the entire PDU Session1 that is currently carrying the service on the MN side to the SN (gNB1).
