Therefore, the Public Land Mobile Network (PLMN) provided by the core network element and the tracking area information supported by the base station do not change. However, in a Non-Terrestrial Networks (NTN) communication system, the base station may have a mobile characteristic. Therefore, the tracking area information supported by the base station changes as the base station moves. In this case, using the old tracking area information will affect the normal operation of the interface between the base station and the core network node. For example, when the core network element sends a paging message, how to improve the paging performance for the terminal is an urgent problem to be solved. Summary of the Invention

[0044] The terminal can also be referred to as a user equipment (UE), a terminal device, an access terminal, a user unit, a user station, a mobile station, a mobile platform, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device, etc.

[0045] The network-side device 12 may include an access network device or a core network device. Among them, the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node, etc. Among them, the base station may be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, relay base station (RBS), serving base station (SBS), base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home Node B (HNB), home evolved Node B, transmission reception point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0046] In some embodiments of this application, the access network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of this application, the network device may also be a base station set at locations such as land and water areas.

[0047] In some embodiments of the present application, the core network device may also be referred to as a core network node, a core network element, or a core network function. For example, it may include at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of the present application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0048] To facilitate the understanding of the embodiments of the present application, Non-Terrestrial Networks (NTN) will be described.

[0049] The NTN communication system includes: an NTN communication system based on transparent payload and an NTN communication system based on regenerative payload. In some scenarios, only the NTN communication system based on transparent payload is considered. In this deployment environment, the terminal, the base station, and the core network equipment are all deployed on the ground, and the communication data between the terminal and the network equipment is relayed via a satellite in the air. In this system, the satellite is only used to forward the data between the base station and the terminal, and does not decode and process this data. For the NTN communication system based on regenerative payload, the satellite has some or all of the base station functions and can decode and process uplink or downlink data. Exemplarily, if the satellite has all the functions of the access network, the access network equipment can be called the on-satellite access network equipment or the on-satellite base station equipment. In popular terms, it can also be called the base station on the satellite. In this case, the function of the Centralized Unit (CU) of the access network is called the CU of the on-satellite access network, and the function of the Distributed Unit (DU) of the access network is called the DU of the on-satellite access network. If the satellite has the function of the CU of the access network, the CU of the access network can be called the on-satellite CU of the access network equipment. In popular terms, it can also be called the CU on the satellite. If the satellite has the function of the DU of the access network, the DU of the access network can be called the on-satellite DU of the access network equipment. In popular terms, it can also be called the DU on the satellite.

[0050] In the NTN communication system, to achieve data or signaling interaction between the terminal and the terrestrial network, it is necessary to ensure that the service link and the feeder link can be connected simultaneously, as Figure 2 . However, in some cases, such as in the initial stage of satellite network deployment, it cannot be guaranteed that the service link and the feeder link can be connected simultaneously. To support data transmission (e.g., delay-tolerant service data), a store-and-forward (S&F) communication mode is proposed, as Figure 3 . Taking the uplink data transmission as an example, when the terminal has uplink data to send, it can first send it to the satellite through the service link (such as Figure 3 step A), and the satellite stores the relevant data. When the satellite moves to a position where the feeder link is available, it forwards the stored data to the terrestrial network (such as Figure 3 step B). Similarly, when there is downlink data to be sent to the terminal, the terrestrial network first sends the data to the satellite, and the satellite stores the relevant downlink data. When the satellite moves to a position where the service link is available, it forwards the stored data to the terminal.

[0051] Figure 4A typical NTN deployment scenario is shown. The link between the UE and the satellite is called the service link, and the link between the satellite and the terrestrial gateway is called the feeder link. In some scenarios (such as low Earth orbit satellites, LEO), due to satellite movement, handovers of the service link and / or the feeder link may occur. For service link handover, the serving satellite for all UEs within a cell needs to be switched from one satellite to another. For feeder link handover, a certain satellite needs to be switched from one terrestrial gateway to another.

[0052] To facilitate the understanding of the embodiments of this application, the S1 / Next Generation (NG) interface management will be described.

[0053] In the LTE communication system, the interface between the base station and the core network element is the S1 interface. In the NR communication system, the interface between the base station and the core network element is the NG interface. The S1 interface and the NG interface include the control plane interface S1-C / NG-C and the user plane interface S1-U / NG-U. Among them, the user plane interface S1-U / NG-U is connected to the core network user plane element, such as the Serving GateWay (S-GW) or UPF, for transmitting service data. The control plane interface S1-C / NG-C is connected to the core network control plane element MME / AMF for transmitting control plane information. The management of the S1 interface and the management of the NG interface are similar. The following will take NR as an example to introduce the management process of the NG interface. For example, it includes the establishment process and the reset process of the NG interface.

[0054] Figure 5 A NG interface establishment process (NG setup procedure) is shown. As Figure 5 shown, the NG setup procedure is initiated by the base station. For example, in S301, the base station can send a NG setup request message to the AMF. If the AMF agrees to establish, then in S302, the AMF replies with a NG setup response message. If the AMF cannot accept the NG setup request, it replies with a NG setup failure message.

[0055] In the related art, both the base station and the core network element are fixedly deployed on the ground. Therefore, during the establishment process of the interface between the base station and the core network element, the Public Land Mobile Network (PLMN) supported by the base station, the tracking area information, etc. will not change.

[0056] However, under the Store and Forward (S&F) mechanism, the tracking area managed by non-terrestrial base stations (such as dangerous ones) will change with their own movement. In some cases, the feeder link may also be unavailable. Therefore, how to ensure the normal operation between the base station and the core network element is an urgent problem to be solved.

[0057] Next, in combination with the accompanying drawings, the wireless communication method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0058] Figure 6 It is a schematic diagram of a wireless communication method provided by an embodiment of the present application. As Figure 6 shown, the method 400 includes at least the following parts:

[0059] S401, the non-terrestrial base station sends the first information to the core network element;

[0060] Correspondingly, the core network element receives the first information from the non-terrestrial base station;

[0061] Wherein, the first information is used to indicate at least one of the following:

[0062] The base station type-related information of the non-terrestrial base station;

[0063] The tracking area-related information covered by the non-terrestrial base station within a preset time.

[0064] In some embodiments, the core network element may include, for example, but not limited to at least one of the following:

[0065] Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc.

[0066] In some embodiments, the non-terrestrial base station may be a base station deployed using spaceborne tools or airborne tools. The spaceborne tools may include but are not limited to satellites. For example, the satellites may include but are not limited to low earth orbit (LEO) satellites, medium earth orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, High Elliptical Orbit (HEO) satellites, etc. The airborne tools include, for example, High Altitude Platform (HAP), such as but not limited to Unmanned Aerial Vehicle (UAV) systems.

[0067] In the embodiments of the present application, the base station deployed using spaceborne tools is also referred to as an on-orbit base station.

[0068] In some embodiments, the base station type can be divided according to the capabilities of the non-terrestrial base station and / or the height of the operating orbit.

[0069] Optionally, the capabilities of the non-terrestrial base station include, for example, but are not limited to: whether the non-terrestrial base station supports store-and-forward (S&F), and whether the non-terrestrial base station supports processing of uplink and downlink data, such as whether it supports the regenerative load function.

[0070] Optionally, the height of the operating orbit of the non-terrestrial base station can include, for example, but is not limited to at least one of the following: high orbit, medium orbit, and low orbit.

[0071] Exemplarily, the base station type of the non-terrestrial base station includes, for example, but is not limited to at least one of the following:

[0072] Regenerative payload type;

[0073] Store-and-forward (S&F) type;

[0074] High-orbit regenerative payload type;

[0075] Medium-orbit regenerative payload type;

[0076] Low-orbit regenerative payload type;

[0077] High-orbit store-and-forward type;

[0078] Medium-orbit store-and-forward type;

[0079] Low-orbit store-and-forward type.

[0080] Optionally, in an NB-IOT (Narrow Band Internet of Things) communication system, the base station type of the non-terrestrial base station includes, for example, but is not limited to at least one of the following:

[0081] NB-IOT regenerative payload type;

[0082] NB-IOT store-and-forward (S&F) type;

[0083] NB-IOT high-orbit regenerative payload type;

[0084] NB-IOT medium-orbit regenerative payload type;

[0085] NB-IOT low-orbit regenerative payload type;

[0086] NB-IOT high-orbit store-and-forward type;

[0087] NB-IOT Medium Orbit Storage and Forwarding Type

[0088] NB-IOT Low Orbit Storage and Forwarding Type

[0089] In some embodiments, the base station of the S&F type supports storing and forwarding the received messages.

[0090] For example, when the feeder link between the base station of the S&F type and the core network element is unavailable, the base station can store the message received from the terminal and to be sent to the core network element, and then forward the message to the core network element when the feeder link is available.

[0091] It should be noted that in the embodiments of the present application, the feeder link can be understood or replaced by a feeder line. Among them, the feeder link will be unavailable can be understood or replaced by the feeder link is about to be unavailable, the feeder link will be disconnected, the feeder link is about to be disconnected, the feeder link will be switched, or the feeder link is about to be switched, etc.

[0092] Optionally, the determination of the time point when the feeder link between the non-terrestrial base station and the core network element is unavailable can be set according to actual needs. For example, in some embodiments, it can be defined that when the satellite moves to a specific position, it is assumed or considered that the feeder link is unavailable. One implementation method is to determine the time point when the feeder link is unavailable based on information such as the trajectory and speed of the satellite movement, and then based on this time point, it can be considered that the feeder link will be unavailable at a preset moment before this time point. Another implementation method is to obtain the current position information of the satellite and assume that the feeder link will be unavailable when the satellite moves to a certain position before a specific position.

[0093] Optionally, the determination of the time point when the feeder link between the base station and the core network element is available can be set according to actual needs. The specific setting method can be the same as or similar to the above-mentioned unavailable determination method. This will not be elaborated here and in the following.

[0094] In some embodiments, the base station of the S&F type can refer to a base station of the regenerative load type that supports S&F.

[0095] It should be understood that the above is only an example of dividing the operating orbit of the non-terrestrial base station into high orbit, medium orbit and low orbit, but the present application is not limited to this. In other embodiments, the operating orbit of the non-terrestrial base station can also be divided into more levels, for example, four levels (geosynchronous orbit, high orbit, medium orbit and low orbit), or fewer levels, for example, two levels, such as high orbit and low orbit. The present application does not limit this.

[0096] It should be understood that the embodiments of the present application do not limit the transmission timing of the first information. For example, the non-terrestrial base station may send the first information during the interface establishment process or reset process between the non-terrestrial base station and the core network element, which is beneficial to ensuring the normal operation of the established or reset interface. Or, during the access network configuration update process, the non-terrestrial base station may also indicate the base station type of the non-terrestrial base station and / or information related to the tracking area covered by the non-terrestrial base station within a preset time to the core network element. Or, the first information may also be sent during the data transmission process between the non-terrestrial base station and the core network element, etc.

[0097] In some implementation manners of the present application, S401 may include at least one of the following:

[0098] The non-terrestrial base station sends an interface establishment request message to the core network element, and the interface establishment request message includes the first information. That is, the non-terrestrial base station may indicate the base station type of the non-terrestrial base station and / or information related to the tracking area covered by the non-terrestrial base station within a preset time to the core network element through the interface establishment request message;

[0099] The non-terrestrial base station sends an access network configuration update message to the core network element, and the access network configuration update message includes the first information. That is, the non-terrestrial base station may indicate the base station type of the non-terrestrial base station and / or information related to the tracking area covered by the non-terrestrial base station within a preset time to the core network element during the access network configuration update process.

[0100] Exemplarily, in the NR system, the interface establishment request message may be an NG setup request message, or in the LTE system, the interface establishment request message may be an S1 setup request message.

[0101] In some embodiments of the present application, the method 400 further includes at least one of the following:

[0102] The core network element sends second information to the non-terrestrial base station, and the second information is used to indicate that the core network element supports store and forward, or in other words, the core network element has S&F capabilities;

[0103] The core network element sends an access network configuration update confirmation message to the non-terrestrial base station, and the access network configuration update confirmation message includes the second information.

[0104] In this way, when the core network element needs to send a message to the non-terrestrial base station, but the feeder link between the non-terrestrial base station and the core network element is unavailable, the core network element may first store the message to be sent to the non-terrestrial base station, and then send the message to the non-terrestrial base station when the feeder link is available.

[0105] In some implementations, the core network element sends second information to the non-terrestrial base station, including:

[0106] The core network element sends an interface establishment response message to the non-terrestrial base station, and the interface establishment response message includes the second information. That is, the core network element can indicate to the non-terrestrial base station in the interface establishment response message that the core network element supports store and forward.

[0107] In some embodiments, the interface establishment response message can be an NG setup response message or an S1 setup response message.

[0108] In some embodiments, the first information includes at least one of the following information:

[0109] First indication information for indicating the base station type of the non-terrestrial base station. For example, the first indication information can be information related to the base station type of the non-terrestrial base station;

[0110] Second indication information for indicating information related to the tracking area to be covered by the non-terrestrial base station in the future.

[0111] It should be noted that the above "future" can be understood as a period of time after the non-terrestrial base station provides the above first information to the core network element, and the duration of this period is not limited. Since the non-terrestrial base station can be an on-board device (satellite), and the on-board device can move periodically, the "future coverage" here can correspond to the satellite coverage within this cycle, or the satellite re-coverage after experiencing one or more cycles. For example, when the base station establishes an interface with the core network element, the base station has not covered the tracking area 1 indicated by the tracking area information. After that (for example, after experiencing one or more cycles of operation or within one cycle), the satellite moves to cover the tracking area 1.

[0112] Hereinafter, specific implementations of the first indication information and the second indication information will be described in conjunction with specific embodiments.

[0113] In some embodiments, the first indication information implicitly indicates the base station type of the non-terrestrial base station.

[0114] For example, the first indication information is used to indicate the base station identity (ID) of the non-terrestrial base station, and the base station identity is used to implicitly indicate the base station type of the non-terrestrial base station.

[0115] In some implementations, there is a mapping relationship between the base station identity and the base station type. Therefore, the core network element can obtain the base station type of the non-terrestrial base station according to the base station identity in combination with the mapping relationship.

[0116] In some embodiments, the core network element is configured with or stores the mapping relationship between the base station identifier and the base station type. For example, the mapping relationship is predefined, or it can also be configured for the core network element by Operation Administration and Maintenance (OAM).

[0117] In some other embodiments, the first indication information may explicitly indicate the base station type of the non-terrestrial base station. For example, the first indication information may directly indicate the base station type of the non-terrestrial base station.

[0118] Exemplarily, the first indication information is used to indicate that the base station type of the non-terrestrial base station is one of the following:

[0119] Regenerative payload type;

[0120] Store and Forward (S&F) type;

[0121] High-orbit regenerative payload type;

[0122] Medium-orbit regenerative payload type;

[0123] Low-orbit regenerative payload type;

[0124] High-orbit store and forward type;

[0125] Medium-orbit store and forward type;

[0126] Low-orbit store and forward type.

[0127] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is the regenerative payload type, it means that the non-terrestrial base station is a non-terrestrial base station based on regenerative payload, such as an on-board base station based on regenerative payload.

[0128] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is the S&F type, it means that the non-terrestrial base station is a non-terrestrial base station with S&F capabilities, such as an on-board base station with S&F capabilities.

[0129] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is the high-orbit regenerative payload type, it means that the non-terrestrial base station is a non-terrestrial base station based on high-orbit regenerative payload, such as an on-board base station based on high-orbit regenerative payload.

[0130] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is the medium-orbit regenerative payload type, it means that the non-terrestrial base station is a non-terrestrial base station based on medium-orbit regenerative payload, such as an on-board base station based on medium-orbit regenerative payload.

[0131] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is a low-orbit regeneration load type, it means that the non-terrestrial base station is a non-terrestrial base station based on a low-orbit regeneration load, such as an on-board base station based on a low-orbit regeneration load.

[0132] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is a high-orbit S&F type, it means that the non-terrestrial base station is a non-terrestrial base station based on a high orbit and having S&F capabilities, such as an on-board base station based on a high orbit and having S&F capabilities.

[0133] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is a medium-orbit S&F type, it means that the non-terrestrial base station is a non-terrestrial base station based on a medium orbit and having S&F capabilities, such as an on-board base station based on a medium orbit and having S&F capabilities.

[0134] In some embodiments, when the first indication information indicates that the base station type of the non-terrestrial base station is a low-orbit S&F type, it means that the non-terrestrial base station is a non-terrestrial base station based on a low orbit and having S&F capabilities, such as an on-board base station based on a low orbit and having S&F capabilities.

[0135] In some embodiments, the first indication information may be N bits, where N is a positive integer, and different values of the N bits are used to indicate different base station types.

[0136] Optionally, the number of bits occupied by the first indication information may be determined according to the total number of base station types to be indicated.

[0137] For example, if two types of base stations (such as a regeneration load type and an S&F type) need to be indicated, the first indication information may be 1 bit. Or, if eight types of base stations need to be indicated, the first indication information may be 3 bits.

[0138] Optionally, the first indication information may include a first indication bit and / or a second indication bit, where the first indication bit is used to indicate whether the non-terrestrial base station is a regeneration load type or a store-and-forward type, and the second indication bit is used to indicate whether the non-terrestrial base station is a high orbit, a medium orbit, or a low orbit.

[0139] Optionally, the first indication bit may be 1 bit, and the second indication bit may be 2 bits.

[0140] In some embodiments, the first indication information may also be used to indicate whether the base station type of the non-terrestrial base station is the S&F type. For example, a 1-bit is used to indicate whether the non-terrestrial base station is of the S&F type. Exemplarily, a value of 1 indicates that it is of the S&F type, and a value of 0 indicates that it is not of the S&F type. In another embodiment, when the non-terrestrial base station provides the 1-bit indication to the above core network element (such as the AMF or the MME), it indicates that the non-terrestrial base station is of the S&F type. When the non-terrestrial base station does not provide the above 1-bit indication to the above core network element (such as the AMF or the MME), it indicates that the non-terrestrial base station is not of the S&F type.

[0141] In some embodiments, the information related to the tracking area that the non-terrestrial base station will cover in the future can be understood as the information related to the tracking area that the non-terrestrial base station will manage in the future, or the information related to the tracking area that the non-terrestrial base station will support in the future.

[0142] In some embodiments, the information related to the tracking area that the non-terrestrial base station will cover in the future may include the information related to the tracking area that the non-terrestrial base station will cover at a preset time or a specific time. For example, within the preset time, if the terminal is within the tracking area, the non-terrestrial terminal may support paging the terminal.

[0143] In some embodiments, the preset time may include at least one time point, or at least one time period. The time point or time period may be a future time point or time period, or rather, a time point or time period after the current time.

[0144] For example, if the non-terrestrial base station operates periodically, the preset time may include at least one time point within one operating cycle, or at least one time period within one operating cycle.

[0145] Therefore, by indicating the information related to the tracking area that the non-terrestrial base station will cover in the future, the core network element can know the tracking area that the non-terrestrial base station will cover in the future. Further, according to the tracking area that the non-terrestrial base station will cover in the future, a suitable non-terrestrial base station can be selected to page the terminal, which is beneficial to ensuring the normal communication of the terminal.

[0146] In some implementation manners, the information related to the tracking area that the non-terrestrial base station will cover in the future (such as a preset time or a specific time) includes at least one piece of tracking area information that the non-terrestrial base station will cover in the future (such as a preset time or a specific time). For example, the tracking area information includes at least one of a Tracking Area Code (TAC), a Tracking Area Identity (TAI), and a PLMN Identity.

[0147] In some implementations, the information related to the tracking area to be covered by the non-terrestrial base station in the future (e.g., a preset time or a specific time) further includes the time information associated with the at least one tracking area information. The time information associated with the tracking area information can be a timestamp, or alternatively, it can be a time period. For example, the timestamp can be the start time when the non-terrestrial base station covers the tracking area, and the time period can include the start time and the end time when the non-terrestrial base station covers the tracking area.

[0148] Optionally, the timestamp or the time period can be represented in Coordinated Universal Time (UTC). By way of example, the timestamp can be UTC time 12:00. Exemplarily, the time period can be from UTC time 12:00 to UTC time 12:30.

[0149] In some embodiments, the non-terrestrial base station can also indicate the tracking area information currently covered to a core network element, or rather, the tracking area information currently supported or managed, such as including but not limited to at least one of TAC, TAI, and PLMN identifier.

[0150] In some embodiments, the information related to the tracking area to be covered by the non-terrestrial base station in the future (e.g., a preset time or a specific time) is included in a first tracking area list.

[0151] In some implementations, the first tracking area list only includes the information related to the tracking area to be covered by the non-terrestrial base station in the future. For example, the non-terrestrial base station can indicate the information related to the tracking area to be covered in the future by introducing a new TA list. That is, the first tracking area list can be a newly introduced TA list.

[0152] The non-terrestrial base station can also indicate a second tracking area list to the core network element, and the second tracking area list is the list of the tracking areas currently covered by the non-terrestrial base station. The second tracking area list is also called the Supported TA List.

[0153] Optionally, the first tracking area list can include multiple information elements (IEs), and the multiple IEs are used to carry the tracking area information covered by the non-terrestrial base station at different time points or time periods. For example, one IE is used to carry the tracking area information covered by the non-terrestrial base station at a time point or a time period. Optionally, each IE further includes time information for indicating the time information associated with the tracking area information.

[0154] In some embodiments, the first tracking area list and the second tracking area list are carried in an NG establishment request message.

[0155] For example, the NG setup request message may include the content shown in Table 1 below:

[0156] Table 1

[0157]

[0158]

[0159] Among them, the Additional Supported TA list corresponds to the first tracking area list, which is used to indicate the tracking area-related information that the non-ground base station will support in the future. The Supported TA List corresponds to the second tracking area list, which is respectively used to indicate the tracking area information that the non-ground base station currently supports.

[0160] In some other implementation manners, the first tracking area list includes the tracking area information currently covered by the non-ground base station and the tracking area-related information that the non-ground base station will cover in the future. That is, the non-ground base station can use the same tracking area list to indicate the tracking area information of the current coverage and the future coverage to the core network element.

[0161] Optionally, the first tracking area list is carried in the NG setup request message. For example, the NG setup request message may include the content shown in Table 2 below:

[0162] Table 2

[0163]

[0164] Among them, the Supported TA List corresponds to the first tracking area list, and the Supported TA List includes the tracking area information that the non-ground base station currently supports and will support in the future.

[0165] In some embodiments, the Supported TA List includes supported TA items (Supported TAItem), and the Supported TA Item may include at least one TA list. Among them, the number of TA lists carried in the Supported TA Item is less than or equal to the maximum number of TA lists that can be carried (denoted as maxnoofTotalTACs), and the maxnoofTotalTACs may be predefined or pre-configured.

[0166] For example, the tracking area information that the non-ground base station currently supports and will support in the future is carried in the Supported TAItem.

[0167] In some embodiments, the Supported TA Item includes the current TAC, the future TA list, and the broadcast PLMN list. Among them, the current TAC is used to indicate the tracking area information currently supported by the non-terrestrial base station, such as the TAC corresponding to the currently supported TA. The future TA list is used to indicate the TA-related information that the non-terrestrial base station will support in the future.

[0168] Among them, the future TA list includes the future TAC and the time stamp. The future TAC is used to indicate the TAC corresponding to the future TA of the non-terrestrial base station, and the time stamp is used to indicate the time associated with the future TAC.

[0169] Among them, the broadcast PLMN list is used to indicate the PLMN identifiers supported by the non-terrestrial base station.

[0170] It should be understood that the hierarchical relationship of the tracking area information in Table 2 is only an example, and this application does not limit it.

[0171] For example, the Supported TA List may include the current TA list and the future TA list. Among them, the current TA list includes the current TAC and the broadcast PLMN list, and the future TA list may include the future TAC and the time stamp. Optionally, the future TA list may also include the broadcast PLMN list, indicating the PLMNs supported in the future.

[0172] In some embodiments, the first information can be used by the core network element to obtain the base station type of the non-terrestrial base station.

[0173] For example, when the first information includes the first indication information, the core network element can obtain the base station type of the non-terrestrial base station according to the first indication information.

[0174] In some implementation manners, the first indication information is used to indicate the base station identifier, and there is a mapping relationship between the base station identifier and the base station type. Exemplarily, base station IDs 1 to 6 correspond to the regenerative load type, and base station IDs 7 to 14 correspond to the S&F type. If the first indication information indicates base station ID8, the core network element can know that the non-terrestrial base station is of the S&F type.

[0175] In some other implementation manners, the first indication information is used to indicate that the base station type of the non-terrestrial base station is the S&F type, then the core network element can know that the base station type of the non-terrestrial base station is the S&F type according to the first indication information.

[0176] In some embodiments, the second indication information can also be used to implicitly indicate the base station type of the non-terrestrial base station.

[0177] For example, whether the first information includes second indication information for implicitly indicating whether the base station type of the non-terrestrial base station is a specific base station type, and the specific base station type includes, for example, the S&F type.

[0178] Exemplarily, in the case where the first information includes second indication information, that is, when the non-terrestrial base station indicates information related to the tracking area of future coverage to the core network element, it is used to indicate that the base station type of the non-terrestrial base station is a specific base station type, such as the S&F type.

[0179] In other words, in the case where the base station type of the non-terrestrial base station is a specific base station type, such as the S&F type, the first information includes second indication information. That is, in the case where the base station type of the non-terrestrial base station is a specific base station type, such as the S&F type, the non-terrestrial base station only then indicates information related to the tracking area of future coverage to the core network element.

[0180] Exemplarily, in the case where the first information does not include second indication information, that is, when the non-terrestrial base station does not indicate information related to the tracking area of future coverage to the core network element (or rather, only indicates the information of the currently covered tracking area to the core network element), it means that the base station type of the non-terrestrial base station is not a specific base station type, such as not the S&F type.

[0181] In other words, in the case where the base station type of the non-terrestrial base station is not a specific base station type, such as not the S&F type, the first information does not include second indication information, that is, the non-terrestrial base station does not indicate information related to the tracking area of future coverage to the core network element.

[0182] In some embodiments, non-terrestrial base stations and core network elements of the S&F type may not be connected, resulting in the feeder link between the non-terrestrial base stations and core network elements of the S&F type being unavailable. Therefore, when the tracking area of a non-terrestrial base station changes due to the operation of the non-terrestrial base station, the non-terrestrial base station may not be able to trigger a tracking area configuration update in a timely manner, and the core network element may also not be able to learn the change in the tracking area of the non-terrestrial base station in a timely manner, which may further affect the normal operation of the interface between the non-terrestrial base station and the core network element. For example, it may cause the core network element to send a paging message, but the non-terrestrial base station cannot receive it, thereby affecting the normal communication of the terminal. For the above reasons, in the embodiments of the present application, for non-terrestrial base stations of the S&F type, information related to the tracking area to be covered in the future can be indicated to the core network element, so that the core network element can learn the tracking area information covered by the non-terrestrial base station at different times, and thus the core network element can select a suitable base station for paging the terminal according to the tracking area information, which is beneficial to ensuring the normal communication of the terminal. Optionally, for other types of non-terrestrial base stations, the change in the tracking area of the non-terrestrial base station can be updated through the tracking area configuration update process. Or, other types of non-terrestrial base stations can also use a similar method as non-terrestrial base stations of the S&F type to indicate information related to the tracking area to be covered in the future to the core network element.

[0183] In some embodiments of the present application, the method 400 further includes:

[0184] When the non-terrestrial base station is a base station of the S&F type, the core network element performs a first operation;

[0185] Wherein, the first operation includes at least one of the following:

[0186] When the core network element needs to page a terminal and the feeder link between the core network element and the non-terrestrial base station is available, the core network element sends the paging message of the terminal to the non-terrestrial base station;

[0187] When the feeder link between the core network element and the non-terrestrial base station is unavailable, suspend the interface transmission between the core network element and the non-terrestrial base station;

[0188] When the core network element needs to page a terminal and the tracking area where the terminal is located is included in the tracking area to be covered in the future or the currently covered tracking area of the non-terrestrial base station, the core network element sends the paging message of the terminal to the non-terrestrial base station;

[0189] When the core network element needs to page a terminal and the tracking area where the terminal is located is not included in the tracking area to be covered by the non-terrestrial base station in the future or the currently covered tracking area, the core network element determines not to send the paging message of the terminal to the non-terrestrial base station;

[0190] When the core network element needs to page a terminal, the core network element sends the paging message of the terminal to the non-terrestrial base station.

[0191] In some implementation manners, suspending the interface transmission between the first device and the second device can be implemented through the following mechanism:

[0192] The first device sends a first request message to the second device. Wherein, the first request message is used to request the second device to suspend the interface transmission;

[0193] Wherein, the first request message includes at least one of the following:

[0194] Suspension reason indication information, which is used to indicate that the feeder link is unavailable or will be unavailable;

[0195] Suspension type indication information, which is used to indicate suspending the transmission function of part of the interface or suspending the transmission function of part of the interface;

[0196] Suspension time information.

[0197] In some embodiments, the first device automatically resumes at least one of the interface transmission and the restoration of the terminal context based on the suspension time information.

[0198] In some embodiments, the first device can also receive a first response message from the second device. Wherein, the first response message is used to indicate that the second device agrees to suspend the interface transmission.

[0199] In some embodiments, the first device is an access network device, such as the aforementioned non-terrestrial base station, and the second device is a core network element.

[0200] In some embodiments, the suspension time information may include at least one of the following:

[0201] Suspension start time information;

[0202] Suspension duration information;

[0203] Suspension end time information;

[0204] Time information for the interface to resume transmission.

[0205] In some embodiments, the core network element transmits data to and from the terminal via a store-and-forward type of base station; and / or, the terminal is enabled with a store-and-forward function.

[0206] In other words, the terminal may be a terminal that transmits data to and from the core network element via a store-and-forward type of base station, and / or a terminal enabled with a store-and-forward function.

[0207] That is to say, for this type of terminal, the core network element may use the above method to page the terminal.

[0208] In some embodiments, the terminal may be a low-mobility terminal or a stationary terminal. That is, when the non-terrestrial base station moves to the tracking area where the terminal is currently located in the future, the tracking area where the terminal is located does not change. In this way, the core network element can effectively page the terminal through the non-terrestrial base station.

[0209] In some embodiments, when the core network element needs to page a terminal, the core network element may determine whether to page the terminal through the non-terrestrial base station according to third information.

[0210] Wherein, the third information includes at least one of the following:

[0211] The availability of the feeder link between the core network element and the non-terrestrial base station;

[0212] The tracking areas supported by the non-terrestrial base station, for example, including the currently supported and future (e.g., preset time) supported tracking areas. The method for determining the availability of the feeder link between the core network element and the non-terrestrial base station refers to the description of the foregoing embodiments. For the sake of brevity, it will not be elaborated here.

[0213] It can be understood that when the feeder link between the core network element and the non-terrestrial base station is available, the non-terrestrial base station can receive the paging message sent by the core network element through the feeder link. In this case, the core network element sends the paging message to the non-terrestrial base station, which is conducive to ensuring the timely paging of the terminal. When the feeder link between the core network element and the non-terrestrial base station is unavailable, the non-terrestrial base station cannot receive the paging message sent by the core network element through the feeder link. In this case, even if the core network element sends the paging message to the non-terrestrial base station, the non-terrestrial base station cannot receive the paging message, and thus the timely paging of the terminal cannot be achieved. In this case, the core network element can determine not to send the paging message to the non-terrestrial base station. Optionally, in this case, the core network element can send the paging message to other non-terrestrial base stations, where the feeder link between the core network element and the other non-terrestrial base stations is available, and / or the tracking area supported by the non-terrestrial base station includes the tracking area where the terminal is currently located. Optionally, the non-terrestrial base station is also a store-and-forward type base station.

[0214] It can be understood that when the tracking area supported by the non-terrestrial base station includes the tracking area where the terminal is currently located, the core network element can page the terminal through the non-terrestrial base station. In this case, the core network element can send the paging message of the terminal to the non-terrestrial terminal. When the tracking area supported by the non-terrestrial base station does not include the tracking area where the terminal is currently located, the core network element cannot page the terminal through the non-terrestrial base station. In this case, even if the core network element sends the paging message to the non-terrestrial base station, the non-terrestrial base station cannot page the terminal.

[0215] Therefore, the core network element performs paging of the terminal according to the third information, which is conducive to ensuring the paging performance of the terminal and thus ensuring the normal communication of the terminal.

[0216] In some specific implementation manners, when the following conditions are met, the core network element determines to page the terminal through the non-terrestrial base station, that is, sends the paging message of the terminal to the non-terrestrial base station:

[0217] The feeder link between the core network element and the non-terrestrial base station is available;

[0218] The tracking area supported by the non-terrestrial base station includes the tracking area where the terminal is currently located. For example, the tracking area that the non-terrestrial base station will support or currently supports includes the tracking area where the terminal is currently located.

[0219] Therefore, when the feeder link between the core network element and the non-terrestrial base station is available and the tracking area supported by the non-terrestrial base station includes the tracking area where the terminal is currently located, paging the terminal through the non-terrestrial terminal is conducive to ensuring the effective paging of the terminal.

[0220] In some other specific implementation manners, when at least one of the following conditions is satisfied, the core network element determines not to page the terminal through the non-terrestrial base station, that is, does not send the paging message of the terminal to the non-terrestrial base station:

[0221] The feeder link between the core network element and the non-terrestrial base station is unavailable;

[0222] The tracking area supported by the non-terrestrial base station does not include the tracking area where the terminal is currently located. For example, neither the tracking area supported by the non-terrestrial base station in the future nor the tracking area supported currently includes the tracking area where the terminal is currently located.

[0223] Therefore, when the feeder link between the core network element and the non-terrestrial base station is unavailable and / or the tracking area supported by the non-terrestrial base station does not include the tracking area where the terminal is currently located, not paging the terminal through the non-terrestrial base station helps to avoid invalid paging of the terminal.

[0224] Hereinafter, in combination with Embodiment 1 and Embodiment 2, the specific process of the wireless communication method according to the embodiments of the present application will be described.

[0225] Embodiment 1:

[0226] In this Embodiment 1, the first information is used to indicate information related to the base station type of the non-terrestrial base station.

[0227] For example, the first information includes first indication information.

[0228] As Figure 7 shown, the wireless communication method may include the following steps:

[0229] S501, The non-terrestrial base station sends the first information to the core network element, which is used to indicate information related to the base station type of the non-terrestrial base station.

[0230] For example, the first information is used to indicate the base station identifier of the non-terrestrial base station, and there is a mapping relationship between the base station identifier and the base station type.

[0231] Again, for example, the first information is used to indicate the base station type of the non-terrestrial base station. For example, different values of the first information are used to indicate different base station types.

[0232] S502, The core network element sends the second information to the non-terrestrial base station, which is used to indicate that the core network element supports store-and-forward, that is, the core network element has the ability of store-and-forward.

[0233] Optionally, the first information and the second information may be interacted during the interface establishment process, or may also be interacted during the interface reset process.

[0234] Optionally, the first information and the second information may be interacted during the access network configuration update process.

[0235] In some embodiments, the first information is carried in an interface establishment request message. For example, the interface establishment request message may include, but is not limited to, NG setup request, S1 setup request.

[0236] In some embodiments, the second information is carried in an interface establishment response message. For example, the interface establishment response message may include, but is not limited to, NG setup response, S1 setup response.

[0237] In some embodiments, the first information is carried in an access network configuration update message.

[0238] In some embodiments, the second information is carried in an access network configuration update confirmation message.

[0239] S503, the core network element obtains the base station type of the non-terrestrial base station according to the first information.

[0240] For example, it is learned from the first information whether the non-terrestrial base station is of the S&F type.

[0241] S504, when the base station type of the non-terrestrial base station is of the S&F type, perform a first operation.

[0242] In some embodiments, the first operation includes at least one of the following:

[0243] When the core network element needs to page the terminal and the feeder link between the core network element and the non-terrestrial base station is available, the core network element sends the paging message of the terminal to the non-terrestrial base station;

[0244] When the feeder link between the core network element and the non-terrestrial base station is unavailable, suspend the interface transmission between the core network element and the non-terrestrial base station, for example, do not send a paging message to the non-terrestrial base station.

[0245] Since it may be impossible to connect between the non-terrestrial base station of the S&F type and the core network element, resulting in the feeder link between the non-terrestrial base station and the core network element being unavailable, therefore, when the core network element needs to page the terminal through the non-terrestrial base station, considering the availability of the feeder link between the non-terrestrial base station and the core network element to determine whether to page the terminal through the non-terrestrial base station is beneficial to ensuring the paging performance of the terminal.

[0246] Embodiment 2:

[0247] In this Embodiment 2, the first information is used to indicate information related to a tracking area covered by a non-terrestrial base station within a preset time.

[0248] For example, the first information includes second indication information.

[0249] As Figure 8 shown, the wireless communication method may include the following steps:

[0250] S601. The non-terrestrial base station sends the first information to a core network element, for indicating information related to a tracking area that the non-terrestrial base station will cover in the future.

[0251] In some implementation manners, the first information may include at least one tracking area information that the non-terrestrial base station will cover in the future (for example, a preset time or a specific time).

[0252] In some other implementation manners, the first information includes at least one tracking area information that the non-terrestrial base station will cover in the future and time information associated with each tracking area information.

[0253] In some embodiments, when information related to a tracking area that the non-terrestrial base station will cover in the future is carried in an interface establishment request message, it implicitly indicates that the base station type of the non-terrestrial base station is a specific base station type, for example, the S&F type.

[0254] S602. The core network element sends second information to the non-terrestrial base station, for indicating that the core network element supports store-and-forward, that is, the core network element has the store-and-forward capability.

[0255] Optionally, the first information and the second information may be interacted during an interface establishment process, or may also be interacted during an interface reset process.

[0256] Optionally, the first information and the second information may be interacted during an access network configuration update process.

[0257] In some embodiments, the first information is carried in an interface establishment request message. For example, the interface establishment request message may include, for example, but not limited to, an NG setup request, an S1 setup requenst.

[0258] In some embodiments, the second information is carried in an interface establishment response message. For example, the interface establishment response message may include, for example, but not limited to, an NG setup response, an S1 setup response.

[0259] In some embodiments, the first information is carried in an access network configuration update message.

[0260] In some embodiments, the second information is carried in an access network configuration update acknowledgment message.

[0261] S503. The core network element obtains the base station type of the non-terrestrial base station according to the first information.

[0262] For example, in the case where the first information includes information related to the tracking area covered by the non-terrestrial base station in the future, it is known that the non-terrestrial base station is of the S&F type.

[0263] S504. In the case where the base station type of the non-terrestrial base station is of the S&F type, perform a first operation.

[0264] In some embodiments, the first operation includes at least one of the following:

[0265] In the case where the core network element needs to page a terminal and the tracking area where the terminal is located is included in the tracking area covered by the non-terrestrial base station in the future or the currently covered tracking area, the core network element sends the paging message of the terminal to the non-terrestrial base station;

[0266] In the case where the core network element needs to page a terminal and the tracking area where the terminal is located is not included in the tracking area covered by the non-terrestrial base station in the future or the currently covered tracking area, the core network element determines not to send the paging message of the terminal to the non-terrestrial base station;

[0267] In the case where the core network element needs to page a terminal, the core network element sends the paging message of the terminal to the non-terrestrial base station.

[0268] Since the tracking area of the non-terrestrial base station changes as it operates, the non-terrestrial base station can send information related to the tracking area covered in the future to the core network element. Thus, the core network element can obtain the tracking area information covered by the non-terrestrial base station at different times. Further, when paging a terminal is required, it can be considered whether the tracking area supported by the non-terrestrial base station includes the tracking area where the terminal is located, so as to ensure that a suitable non-terrestrial terminal is selected for paging the terminal, thereby ensuring the paging performance of the terminal.

[0269] In summary, in the embodiments of the present application, the non-terrestrial base station can indicate information related to the base station type of the non-terrestrial base station and / or information related to the tracking area of the non-terrestrial base station to the core network element, so that the core network element can obtain the base station type and / or tracking area of the non-terrestrial base station, which is convenient for the core network element to better perform paging on the terminal.
