[0075] To facilitate a clearer understanding of the embodiments of this application, some relevant background technical knowledge is introduced as follows.

[0076] I. Introduction to NTN (Non-terrestrial networks)

[0077] Figure 2 is a schematic diagram of a typical NTN deployment scenario in the related art, such as Figure 2As shown, the link between the user equipment (UE) and the satellite is called the service link (i.e., service link), and the link between the satellite and the terrestrial gateway is called the feeder link (i.e., feeder link). In some scenarios (such as low Earth orbit satellites LEO), due to satellite movement, handover of the service link and / or 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 terrestrial gateway.

[0078] The NTN communication system includes two types: the NTN communication system based on transparent payload and the NTN communication system based on regenerative payload. In 3GPP Releases 17 and 18, 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 the 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, the access network equipment can also be called the base station on the satellite. In this case, the central unit CU function of the access network is called the CU of the on-satellite access network, and the DU function of the access network is called the distributed unit DU of the on-satellite access network. If the satellite has the central unit CU function of the access network, the central unit 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 DU function 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.

[0079] II. Introduction to S&F (Store and Forward)

[0080] Figure 3 is a schematic diagram of a normal / default satellite communication system in the related art, such as Figure 3 As shown, in the NTN communication system, to enable data or signaling interaction between the UE and the terrestrial network, it is necessary to ensure that the service link and the feeder link can both remain connected simultaneously.

[0081] 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 maintain a connection simultaneously. To support data transmission (e.g., delay-tolerant service data), a store-and-forward communication mode is proposed. Figure 4 It is a schematic diagram of a satellite communication system based on store-and-forward in the related art. For example, Figure 4 As shown, 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 (as shown in step A in the figure), 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 ground network (as shown in step B in the figure). Similarly, when there is downlink data to be sent to the terminal, the ground 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 UE.

[0082] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the uplink data processing method and the downlink data processing method provided by the embodiments of the present application will be described in detail.

[0083] In the related art, in an NTN communication system, to achieve data or signaling interaction between a terminal and a ground network, it is necessary to ensure that the service link and the feeder link can maintain a connection simultaneously. In the S&F mechanism, due to satellite movement, the service link will experience multiple changes from service link available → service link unavailable → service link available. In this scenario, how the S&F base station processes the terminal's data is a problem that needs to be solved.

[0084] Based on the above problems, the present application provides an uplink data processing method and a downlink data processing method, which can solve the problem of how the S&F base station processes the terminal's data.

[0085] The uplink data processing method and the downlink data processing method provided by the embodiments of the present application can be applied to the NTN scenario. When the service link between the first device and the target terminal among at least one terminal is available, the target terminal receives the second data of the target terminal sent by the first device. Since the second data is determined by the first device receiving the second data related to at least one terminal sent by the second device and storing the second data related to each terminal when the feeder link between the first device and the second device is available, and the second data is related to the target terminal, and the first device is related to the satellite, such that in the scenario of the S&F mechanism, the target terminal receives the second data sent by the first device according to the state of the service link, realizes flexible processing of the downlink data, and further ensures data interaction between the terminal and the second device, thereby improving the management efficiency of the system.

[0086] Figure 5 It is one of the flow schematic diagrams of the downlink data processing method provided by the embodiments of the present application. For example,Figure 5 As shown in Figure 5 , the method includes step 501; where:

[0087] Step 501: When the service link between the first device and the target terminal among at least one terminal is available, the target terminal receives the second data of the target terminal sent by the first device; the second data is determined by the first device receiving at least one terminal-related second data sent by the second device and storing each of the terminal-related second data when the power feed link between the first device and the second device is available; where the second data is related to the target terminal, and the first device is related to a satellite.

[0088] It should be noted that the embodiments of the present application can be applied to the S&F scenario. The target terminal includes but is not limited to the types of terminal 11 listed above. The first device and the second device include but are not limited to the types of network-side device 12 listed above. The embodiments of the present application do not limit this. The first device is related to a satellite, and the second device is a core network element. The type of the target terminal can be of the S&F type, and the type of the first device can be of the S&F type. The target terminal is any one of at least one terminal.

[0089] It should be noted that in the embodiments of the present application, the power feed link can be understood or replaced with a power feed line. Among them, the power feed link will be unavailable can be understood or replaced with the power feed link is about to be unavailable, the power feed link will be disconnected, the power feed link is about to be disconnected, the power feed link will be switched, or the power feed link is about to be switched, etc. When the first device is on the satellite, the unavailability of the feeder link can also be understood as the first device being disconnected or about to be disconnected from the ground gateway, etc.

[0090] Optionally, the determination of the time point when the power feed link 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 power feed link is unavailable. One implementation method is to determine the time point when the power feed link is unavailable based on information such as the trajectory and speed of the satellite movement. Then, based on this time point, it can be considered that the power feed 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 power feed link will be unavailable when the satellite moves to a certain position before a specific position.

[0091] It should be noted that in the embodiments of the present application, the availability of the service link can be understood as the connection of the service link between the terminal and the on-satellite base station. Generally speaking, the availability of the service link can be understood as that the terminal is under the coverage of the on-satellite base station of the above satellite, or there is a satellite corresponding to the on-satellite base station above the head of the terminal. The unavailability of the service link can be understood as the disconnection of the service link between the terminal and the on-satellite base station. Generally speaking, the unavailability of the service link can be understood as that the terminal is not under the coverage of the on-satellite base station of the above satellite, or there is no satellite corresponding to the on-satellite base station above the head of the terminal.

[0092] It should also be noted that there is no fixed order of occurrence between the situation of service link unavailability and service link availability, and the present application does not limit this. As mentioned above, due to the periodic operation of the satellite, the terminal will experience multiple changes such as service link availability → service link unavailability → service link availability, etc. Therefore, there is no fixed order of occurrence between the situation of service link unavailability and service link availability.

[0093] Optionally, the target terminal includes at least one of the following: a terminal with store-and-forward capability; a terminal that transmits data through store-and-forward operations.

[0094] Optionally, the first device includes at least one of the following: a device with store-and-forward capability; the Centralized Unit (CU) of the on-satellite base station; the on-satellite central unit CU of the base station; the on-satellite base station device.

[0095] Specifically, the target terminal can perform data transmission with the second device based on the S&F mechanism. When the service link between the target terminal and the first device is available, the target terminal establishes an air interface connection with the first device. However, due to the movement of the first device, during data transmission, the service link between the target terminal and the first device will experience multiple changes of service link available → service link unavailable → service link available, and the power supply link between the first device and the second device will also experience multiple changes of power supply link available → power supply link unavailable → power supply link available. Specifically, under the S&F mechanism, for example, during the registration process, the terminal needs to perform data transmission with the core network element, and during this period, the terminal will experience multiple processes of service link available → service link unavailable → service link available. Of course, processes such as Mobile Originated Early Data Transmission (MO-EDT), Mobile Terminated Early Data Transmission (MT-EDT), Control Plane CIoT EPS / 5GS optimisation, User Plane CIoT EPS / 5GS optimisations, etc. may occur. This application is applicable to, but not limited to, the above scenarios. Additionally, it should be noted that this application is at least applicable to connection management when the service link is available or unavailable during the above certain processes.

[0096] It should be noted that there is no fixed sequence of occurrence for the change of the power supply link between the first device and the second device and the change of the service link between the first device and the target terminal, and this application does not limit this.

[0097] When the first device moves to a certain position, the power supply link between the first device and the second device is available, and the service link between the first device and the target terminal is unavailable. When the power supply link between the first device and the second device is available, the second device sends second data related to at least one terminal to the first device; wherein, the second data includes one or more of the following: Downlink (DL) Non-Access Stratum (NAS) messages, for example, DL NAS messages in the Cellular Internet of Things (CIOT) signalling optimisation process; DL NAS messages carrying service data; service data. The second data is related to the target terminal, that is, the second data is at least one of the DL NAS messages, DL NAS messages carrying service data, and service data that are interacted between the target terminal and the core network element.

[0098] The first device receives at least one piece of second data related to a terminal sent by the second device and stores the second data related to each terminal. It can be understood that the first device stores the second data of multiple terminals.

[0211] When the target terminal learns that the service link between the first device and the target terminal is available, for example, the target terminal learns that the service link between the on - satellite base station and the target terminal is available based on the ephemeris information of the on - satellite base station, the target terminal actively initiates a random access process; the random access process is used for the target terminal to resume air interface transmission with the first device.

[0212] (d) The first device restores the radio interface connection with the target terminal based on the radio resource control restoration procedure initiated by the target terminal; the radio resource control restoration procedure is used for the target terminal to restore the radio interface connection with the first device.

[0213] It should be noted that when the service link between the first device and the target terminal is unavailable (disconnected), the target terminal suspends the radio interface connection. When the service link between the first device and the target terminal is available (restored), the target terminal restores the radio interface connection. Optionally, the target terminal may retain the UE context.

[0214] Specifically, when the service link between the first device and the target terminal is available, the first device may send the stored second data to the target terminal. Before the first device sends the second data to the target terminal, the first device may wait for the target terminal to restore the radio interface connection.

[0215] When the target terminal learns that the service link between the first device and the target terminal is available, for example, the target terminal learns that the service link between the on-star base station and the target terminal is available based on the ephemeris information of the on-star base station, the target terminal actively initiates a radio resource control restoration procedure; the radio resource control restoration procedure is used for the target terminal to restore the radio interface connection with the first device.

When the service link between the first device and the target terminal is available again, the first device can initiate a paging process to the target terminal according to the location information of the target terminal. The target terminal obtains the paging process initiated by the first device, and the target terminal can establish an air interface connection with the first device again, that is, the first device triggers the target terminal to establish an air interface connection, realizes the establishment of an air interface connection between the first device and the target terminal, ensures the transmission of the downlink data of the target terminal, and improves the data transmission efficiency.

[0221] Optionally, the first device initiating a paging process to the target terminal further includes any one of the following:

[0222] 1) The first device sends a short message to the target terminal; the short message carries paging indication information.

[0223] Specifically, the first device can send a short message to the target terminal, and the target terminal receives the short message sent by the first device, so that the target terminal establishes an air interface connection with the first device. Among them, the short message carries paging indication information, and the short message is used to page the target terminal. For example, a reserved bit is used in the short message, and the reserved bit corresponds to the paging indication information, such as S&F indication. When the reserved bit is set to 1, it indicates an S&F indication.

[0224] It can be understood that the short message is a message sent by the first device to the target terminal, and the first device informs the target terminal of the reason for paging the target terminal. This reason may be that the target terminal has a paging message and the type of the paging message, or the system has changed. At this time, the first device needs to page the target terminal.

[0225] Optionally, the paging indication information is used to indicate at least one of the following: store and forward, that is, the first device forwards the stored second data of the target terminal to the target terminal; downlink data arrival, that is, the downlink data of the target terminal arrives, and the first device needs to send the downlink data to the target terminal.

The first device may obtain the target identity identifier of the target terminal; where the target identity identifier is a core network identity identifier or an access network identity identifier.

[0232] b) The first device sends the second data matching the target identity identifier to the target terminal based on the target identity identifier.

[0253] Next, the downlink data processing method and the uplink data processing method provided by the embodiments of the present application are further described through specific embodiments.

[0254] Embodiment 1: Processing of Terminal Data by the Base Station

[0255] Figure 11 This is the interaction diagram among the UE, the RAN, and the CN provided by the embodiments of the present application. As Figure 11 shown, Step 0: The terminal (UE) transmits data with the core network (CN) element based on the S&F mechanism. When the service link between the terminal and the on-star base station (RAN) is available, the terminal establishes an air interface connection with the on-star base station; wherein, the type of the first on-star base station is an S&F type base station. It should be noted that during the data transmission, the service link will experience multiple changes of service link available → service link unavailable → service link available.

[0256] Step 1: When the service link between the terminal and the on-star base station is available, the terminal sends uplink data to the on-star base station, where the uplink data is one or more of the following: UL NAS message, for example, the UL NAS message in the CIoT signaling optimization process; the UL NAS message carrying service data; service data.

[0257] Step 2: The on-star base station receives the uplink data sent by the terminal. After the on-star base station receives the uplink data sent by the terminal, the on-star base station stores the uplink data.

[0258] Optionally, the actions of the on-star base station further include one or more of the following:

[0259] Record the location information of the terminal, such as global cell identification information and tracking area identification information. Among them, the location information of the terminal is obtained based on the cell information of the cell where the uplink data is received, and the terminal sends the uplink data to the on-board base station through the cell. Optionally, the on-board base station may also record timestamp information related to the location information of the terminal. For example, the timestamp information is the time information when the location information of the terminal is recorded, such as Coordinated Universal Time (UTC) time information

[0260] Generate an interface message with a delay; wherein, the interface message is a message sent by the on-board base station to the core network element, such as an initial UE message (initial UE message).

[0261] Step 3: When the power supply link between the on-board base station and the core network element is available, the on-board base station sends the uplink data to the core network element. When the power supply link between the on-board base station and the core network element is available, the behavior of the on-board base station further includes generating an interface message, and the interface message is used to carry the uplink data.

[0262] Optionally, the interface message also carries the location information of the terminal and the timestamp information related to the location information.

[0263] Step 4: When the power supply link between the on-board base station and the core network element is available, the on-board base station may also receive downlink data (i.e., downlink data) related to the terminal from the core network element. After the on-board base station receives the downlink data related to the terminal, the on-board base station stores the downlink data and delays sending the downlink data to the terminal.

[0264] Among them, the downlink data includes one or more of the following: DL NAS messages, such as DL NAS messages in the CIOT signaling optimization process; DL NAS messages carrying service data; service data.

[0265] Optionally, the behavior of the on-board base station further includes generating a radio interface message with a delay. Among them, the radio interface message is a radio interface message sent by the on-board base station to the terminal, such as an RRC message.

[0266] Step 5: When the service link between the on-board base station and the terminal is available, the on-board base station sends the downlink data to the terminal.

[0267] Optionally, when the service link between the on-board base station and the terminal is available, the behavior of the on-board base station further includes generating a radio interface message. Among them, the radio interface message carries the downlink data.

[0268] Embodiment 2: The on - satellite base station triggers the terminal to establish an air - interface connection. The on - satellite base station associates and stores the downlink data of the terminal based on the core network identity identifier of the terminal, and sends the downlink data to the terminal.

[0269] Figure 12 It is one of the interaction schematic diagrams between the UE and the RAN provided by the embodiments of the present application. As Figure 12 shown, the on - satellite base station stores the downlink data of multiple terminals. Step 0: The terminal (UE) transmits data with the core network (CN) element based on the S&F mechanism. Among them, the type of the on - satellite base station (RAN) is an S&F type base station. It should be noted that during the data transmission, the service link will experience multiple changes of service link available → service link unavailable → service link available. When the service link between the terminal and the on - satellite base station is unavailable, the terminal disconnects or releases the air - interface connection with the on - satellite base station. Optionally, the terminal retains the UE context.

[0270] Step 1: When the service link between the terminal and the on - satellite base station is available, the on - satellite base station can send downlink data to the terminal. Among them, the downlink data can be one or more of the following: DL NAS message, such as the DL NAS message in the CIOT signaling optimization process; the DL NAS message carrying service data; service data.

[0271] Before the on - satellite base station sends the downlink data to the terminal, the actions of the on - satellite base station further include paging the terminal. Optionally, the on - satellite base station pages the terminal by triggering paging or generating a paging message. Among them, the paging message carries the core network identity identifier of the terminal, such as the International Mobile Subscriber Identity (IMSI).

[0272] Optionally, the actions of the on - satellite base station paging the terminal include one or more of the following:

[0273] Carrying paging indication information in the paging message; among them, the paging indication information is used to indicate at least one of the following: store - and - forward; downlink data arrival. For example, the paging indication information can be an S&F indication. Optionally, the paging message can also carry the paging reason information of the terminal, that is, the reason why the on - satellite base station pages the terminal. For example, the downlink data of the terminal arrives.

[0274] Carrying paging indication information in a short message. For example, using a reserved bit in the short message, and the reserved bit corresponds to the paging indication information, such as the S&F indication. For example, when the reserved bit is set to 1, it indicates an S&F indication.

[0275] Optionally, when the terminal receives a paging from the on-board base station, such as a paging message or a short message, the terminal initiates an air interface connection establishment procedure with the on-board base station. During the air interface connection establishment procedure, the terminal provides the core network identity information of the terminal to the on-board base station.

[0276] Optionally, during the air interface connection establishment procedure, the behavior of the terminal further includes one or more of the following: not providing UL NAS messages; providing connection establishment reason information, where the connection establishment reason information may be S&F access.

[0277] Based on the air interface connection establishment procedure, the on-board base station can obtain the core network identity information of the terminal and send the downlink data matching the core network identity information to the terminal.

[0278] Optionally, if the terminal provides UL NAS messages during the air interface connection establishment procedure, the on-board base station ignores or does not process the UL NAS messages.

[0279] Step 2: After the on-board base station sends downlink data to the terminal, the on-board base station can also receive uplink data sent by the terminal.

[0280] Embodiment 3: The terminal actively triggers the establishment of an air interface connection. The on-board base station associates and stores the downlink data of the terminal based on the core network identity of the terminal and sends the downlink data to the terminal

[0281] Figure 13 is the second interaction schematic diagram between the UE and the RAN provided by the embodiments of the present application. As Figure 13 shown, the on-board base station (RAN) stores the downlink data of multiple terminals. Step 0: The terminal (UE) transmits data with the core network element based on the S&F mechanism. The type of the on-board base station is an S&F type base station. It should be noted that during the data transmission, the service link will experience multiple changes of service link available → service link unavailable → service link available. When the service link between the terminal and the on-board base station is unavailable, the terminal disconnects or releases the air interface connection. Optionally, the terminal retains the UE context.

[0282] Step 1: When the service link between the terminal and the on-board base station is available, the on-board base station sends downlink data to the terminal. The downlink data may be one or more of the following: DL NAS messages, such as DL NAS messages in the CIOT signaling optimization process; DL NAS messages carrying service data; service data.

[0283] Before the on - satellite base station sends downlink data to the terminal, the on - satellite base station waits for the terminal to actively establish an air - interface connection. Among them, when the terminal knows that the service link between the terminal and the on - satellite base station is available (for example, learned based on the ephemeris information of the on - satellite base station), the terminal can actively initiate the air - interface establishment process. During the air - interface connection establishment process, the terminal provides the core network identity information of the terminal to the on - satellite base station.

[0284] Optionally, during the air - interface connection establishment process, the behavior of the terminal further includes one or more of the following: not providing UL NAS messages; providing connection establishment reason information, where the connection establishment reason information can be S&F access.

[0285] Based on the air - interface connection establishment process, the on - satellite base station can obtain the core network identity information of the terminal and send the downlink data matching the core network identity information to the terminal.

[0286] Optionally, when the terminal provides UL NAS messages during the air - interface connection establishment process, the on - satellite base station can ignore or not process the UL NAS messages.

[0287] Step 2: After the on - satellite base station sends downlink data to the terminal, the on - satellite base station can also receive the uplink data sent by the terminal.

[0288] Embodiment 4: The terminal actively resumes air - interface data transmission, and the on - satellite base station associates and stores the downlink data of the terminal based on the access network identity of the terminal and sends the downlink data to the terminal

[0289] Figure 14 is the third interaction schematic diagram between the UE and the RAN provided by the embodiments of the present application, as Figure 14 shown, the on - satellite base station (RAN) stores the downlink data of multiple terminals. Step 0: The terminal (UE) transmits data with the core network element based on the S&F mechanism. Among them, the type of the on - satellite base station is an S&F type base station. It should be noted that during the data transmission, the service link will experience multiple changes of service link available → service link unavailable → service link available. When the service link between the terminal and the on - satellite base station is unavailable, the terminal disconnects or releases the air - interface connection. Optionally, the terminal retains the UE context.

[0290] Step 1: When the service link between the terminal and the on - satellite base station is available, the on - satellite base station sends downlink data to the terminal. Among them, the downlink data can be one or more of the following: DL NAS messages, such as DL NAS messages in the CIOT signaling optimization process; DL NAS messages carrying service data; service data.

[0291] Before the on - satellite base station sends downlink data to the terminal, the actions of the on - satellite base station further include waiting for the terminal to resume air - interface transmission. Among them, when the terminal learns that the service link between the terminal and the on - satellite base station is available (for example, learned based on the ephemeris information of the on - satellite base station), the terminal actively initiates a random access process. During the random access process, the terminal provides the access network identity information of the terminal, such as C - RNTI, to the on - satellite base station.

[0292] Based on the random access process, the on - satellite base station obtains the access network identity information of the terminal and sends the downlink data matching the access network identity information to the terminal.

[0293] Step 2: After the on - satellite base station sends downlink data to the terminal, the on - satellite base station can also receive the uplink data sent by the terminal.
