Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and more particularly, to a multi-terminal data processing method, a multi-terminal data processing apparatus, a communication device and a computer readable storage medium. BACKGROUND

[0002] With the development of the communication technology field, non-terrestrial network (NTN) communication has been further developed, especially satellite communication, which has the characteristics of wide coverage, strong disaster resistance and large capacity.

[0003] Remote sensing satellites, as artificial satellites of outer space remote sensing platforms, can use on-board remote sensors to optically or electronically detect the earth's surface and lower atmosphere, obtain relevant information and output corresponding results, such as high-resolution images for city planning, natural disaster prediction, etc. Non-geostationary orbit remote sensing satellites have high resolution and are currently the main type of remote sensing satellites, suitable for high-precision earth observation tasks such as land use and environmental monitoring.

[0004] In traditional remote sensing scenarios, remote sensing data can only be transmitted to the ground within a limited time when the non-geostationary orbit remote sensing satellite passes. The raw data is then pre-processed on the ground before it can be actually used, which results in poor timeliness and low processing efficiency. In particular, high-resolution remote sensing satellites generate massive amounts of raw data, putting a huge pressure on data transmission and reception between the satellite and the ground.

[0005] It should be noted that the information disclosed in the above background section of the invention is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0036] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of exemplary embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the specification.

[0037] Moreover, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the

[0038] The block diagrams in the drawings show only the functionality of the features and can not imply a necessity or particular order of elements. The functionality described can be implemented in software, hardware, or a combination thereof. The block diagrams can also illustrate software, hardware, or a combination thereof, in which different features can be formed through software or hardware components or a combination thereof.

[0039] With the rapid development of communication technology, continuous breakthroughs in new technologies, and the resulting cross-fusion, mobile communication has evolved from "mobile Internet" to "Internet of Things" and further to "Internet of Things". As one of the key technologies for future communication, satellite-ground integrated communication can effectively solve the problem of ground communication network coverage in areas such as sky, ocean, desert, and sparsely populated areas, as well as the problem of emergency communication in natural disasters such as earthquakes and floods.

[0040] Remote sensing satellites, as artificial satellites for outer space remote sensing platforms, can use on-board remote sensors to optically or electronically detect the earth's surface and lower atmosphere, obtain relevant information, and output corresponding results, such as high-resolution images for city planning, natural disaster prediction, etc. Non-geostationary orbit remote sensing satellites have high resolution and are currently the main type of remote sensing satellites, suitable for high-precision earth observation tasks such as land use and environmental monitoring.

[0041] In traditional remote sensing scenarios, remote sensing data can only be transmitted to the ground within a limited time when the non-geostationary orbit remote sensing satellite passes. The raw data is then pre-processed on the ground before it can be actually used, which results in poor timeliness and low processing efficiency. In particular, high-resolution remote sensing satellites generate massive amounts of raw data, putting a huge pressure on data transmission and reception between the satellite and the ground.

[0042] Based on this, the exemplary embodiments of the present disclosure provide a multi-terminal data processing method, as shown in Figure 1 The method comprises:

[0043] Step S110: The on-board user plane function UPF receives the to-be-processed data sent by the terminal through the wireless access network, the to-be-processed data carrying the joint task identifier, the terminal being any one of the multiple terminals corresponding to the joint task identifier;

[0044] Step S120: The on-board UPF sends at least part of the data in the to-be-processed data to the ground UPF for processing to obtain ground processing data, and stores the rest of the data in the to-be-processed data.

[0045] Step S130: The on-board UPF cooperatively processes the rest of the data corresponding to the joint task identifier in the storage to obtain on-board processing data, and sends the on-board processing data to the ground UPF, so that the ground UPF forwards based on the ground processing data and the on-board processing data.

[0046] The terminal can be a satellite, a remote sensing satellite, and can be understood as a multi-access terminal (UE, User Equipment) that can access a satellite access network and a terrestrial access network.

[0047] Exemplarily, Figure 2 A network architecture schematic diagram of satellite data on-orbit processing in a space-air-ground scene is shown. As Figure 2 , the remote sensing satellite accesses the satellite access network and the terrestrial access network as a multi-access UE, the remote sensing satellite captures and collects remote sensing raw data (to-be-processed data), which can be transmitted (for example, part of the large amount of remote sensing raw data such as high-resolution images cannot be immediately transmitted to the ground) to the satellite core network through the satellite access network (wireless access network), and transmitted to the terrestrial core network through the satellite core network, so that the ground UPF (User Plane Function) processes, and correspondingly, the on-board UPF of the satellite core network can also process the raw data and send the obtained on-board processing result to the ground UPF. Accordingly, the data transmission amount between the satellite and the ground can be reduced, and the utilization of satellite computing resources can be optimized.

[0048] Continuing to refer to Figure 2 , for any UPF in the on-board UPF and the ground UPF, the UPF integrates a data processing function DPF (Data Process Function), and the DPF is used for cooperatively processing the rest of the data corresponding to the joint task identifier in the storage to obtain on-board processing data.

[0049] Alternatively, the DPF is independently deployed, and the on-board UPF interacts with the DPF to cooperatively process the rest of the data corresponding to the joint task identifier in the storage to obtain on-board processing data.

[0050] The DPF is used to systematically process remote sensing raw data into operable information through preprocessing, redundancy elimination, image enhancement, feature extraction, compression, etc. Whether deployed independently or integrated in the UPF, the processing of raw data can be realized through the DPF, and after a series of remote sensing data processing procedures, the result data can be efficiently transmitted to the terrestrial core network, thereby reducing the data transmission amount between the satellite and the ground.

[0051] The method of the exemplary embodiments of the present disclosure, on the one hand, for the huge data acquired by the terminal, supports data processing through the on-board UPF, and further through on-orbit processing, greatly reduces the amount of data that needs to be transmitted back to the ground station, effectively saves the communication bandwidth, and optimizes the utilization of resources. On the other hand, on-orbit processing can be performed immediately while data acquisition, realizing the real-time nature of data processing, which is of great significance for some applications with extremely high time efficiency requirements. The terminal can process remote sensing data in real time on-orbit, quickly extract key information and send it to ground decision makers in a timely manner, providing timely and accurate basis for subsequent decision making. Without the need to transmit a large amount of raw data back to the ground for processing, the waiting time for data transmission and ground station queuing processing is avoided, greatly shortening the entire task cycle from data acquisition to final information output, and improving the utilization efficiency and application value of remote sensing data. On the other hand, through the on-board UPF, data fusion and collaborative processing between multiple terminals can be realized, the remote sensing data from different terminals are integrated and analyzed in real time, the advantages of each terminal are fully utilized, and more comprehensive and accurate information products are generated.

[0052] The following will be described in detail Figure 2 Steps S110 to S130 will be described in more detail.

[0053] In step S110, the on-board user plane function UPF receives the to-be-processed data sent by the terminal through the wireless access network. The to-be-processed data carries a joint task identifier, and the terminal is any one of the multiple terminals corresponding to the joint task identifier.

[0054] In the exemplary embodiments of the present disclosure, the on-board UPF is a core network element responsible for processing user data packets, acting as a gateway for data connection to external networks. The traditional UPF is deployed on the ground. The on-board UPF refers to deploying the function of UPF on the satellite, enabling the satellite to have the ability of local data routing, forwarding and preliminary processing. The terminal is various devices participating in collaborative tasks, such as remote sensing satellites. The joint task identifier is a unique ID, used to identify a specific collaborative computing task jointly participated by multiple terminals. All terminals participating in the task will carry this ID in the data packet when sending data. This enables the network (UPF) to identify which data belongs to the same task, thereby unified scheduling and processing.

[0055] In step S120, the on-board UPF sends at least part of the data to be processed to the ground UPF for processing to obtain ground processing data, and stores the rest of the data to be processed.

[0056] In the exemplary embodiments of the present disclosure, the ground UPF is a conventional UPF deployed in a ground data center, connected to powerful cloud computing or edge computing resources, with almost unlimited computing power and storage capacity.

[0057] In some optional embodiments, the on-board UPF sends data exceeding the available data processing amount to the ground UPF as part of the data, and the on-board UPF stores data not exceeding the available data processing amount as the rest of the data, and stores the joint task identifier corresponding to the rest of the data.

[0058] The available data processing amount refers to a quantitative representation of the remaining available computing resources of the on-board UPF. It can be a dynamically changing value, rather than a fixed value. It can be determined according to the remaining available CPU / GPU cycles, remaining memory bandwidth, task throughput, etc. of the on-board UPF. The data to be processed that exceeds the available data processing amount requires more computing resources than the available data processing amount that the on-board UPF can provide at the moment.

[0059] Optionally, the judgment can be performed by the on-board UPF in real time by continuously monitoring the resource status and performing rapid complexity analysis on the data to be processed (such as estimating the computing cost according to the data type, size, and processing algorithm corresponding to the task identifier), to make a decision on whether it can be processed.

[0060] Data not exceeding the available data processing amount is the opposite of the above case, which means that the data requires computing resources less than or equal to the available resources of the on-board UPF at the moment. This means that these data can be processed immediately or scheduled by the on-board UPF without causing system overload. The exemplary embodiments of the present disclosure store data not exceeding the available data processing amount, and send data exceeding the available data processing amount to the ground UPF. By preferentially offloading tasks exceeding the capacity, the on-board resources only process tasks within their capabilities, making the limited on-board computing resources fully utilized, avoiding the delay caused by task queuing, avoiding the risk of on-board system downtime due to overload, and greatly improving the robustness of the system. Moreover, since the on-board UPF simultaneously stores data not exceeding the available data processing amount for its own processing, the amount of data transmitted from the satellite to the ground is reduced, and the response speed is improved.

[0061] In some optional embodiments, the on-board UPF cooperatively processes the rest of the data corresponding to the joint task identifier in the storage to obtain on-board processing data, and sends the on-board processing data to the ground UPF, including:

[0062] First, the on-board UPF will store the corresponding joint task identifier in the remaining data and cooperatively process the data to obtain on-board processing data. The on-board processing data is added with a processed mark. Second, the on-board UPF sends the on-board processing data to the ground UPF through a session of any one of the plurality of terminals, wherein the on-board processing data is directly forwarded by the ground UPF.

[0063] The processed mark refers to a mark added by the on-board UPF to the on-board processing data, such as an identifier added to the header or a specific field of the on-board processing data. The mark can be a signaling for declaring to downstream nodes (especially the ground UPF) in the network that the data has completed all necessary on-board processing and does not need to be analyzed or calculated in the content layer any more, and can be directly forwarded. It can be understood that the indication of the processed mark is used to inform the nature and processing state of the ground UPF.

[0064] The session refers to a stateful connection established between two or more network devices in the communication network for continuous data exchange. It can generally include a unique session ID, address information of both parties, session state (such as active, idle), and other contexts. For example, the session can refer to a session channel established between the terminal and the network for transmitting service data.

[0065] The session of any one of the plurality of terminals refers to that the on-board UPF does not establish a new and independent communication connection for the on-board processing data when sending the data back to the ground, but uses an existing session channel established for a terminal to transmit the data. This avoids the signaling overhead and initial delay of establishing a new session, and improves the link utilization.

[0066] The on-board processing data directly forwarded by the ground UPF refers to a simplified operation performed by the ground UPF after receiving the on-board processing data with the processed mark. The ground UPF does not attempt to analyze the application layer content of the data packet, does not perform any calculation and processing on it, and does not introduce it into a complex service routing chain. The action performed by the ground UPF is very simple, that is, to identify the target address (i.e., the final destination of the cooperative task), and then immediately send it out through the corresponding network port.

[0067] The addition of the processed mark avoids unnecessary processing overhead of the ground UPF, and the session multiplexing can avoid the delay and signaling consumption of establishing a new session, saving the air interface resources and core network signaling resources, so that the network can serve more terminals. The combination of the two significantly reduces the backhaul delay of the on-board processing result.

[0068] The on-board UPF cooperatively processes the remaining data corresponding to the joint task identifier stored in the on-board UPF to obtain on-board processing data. The on-board UPF can fuse, calculate, or the like on the remaining data temporarily stored in the on-board UPF and belonging to the same joint task identifier.

[0069] The on-board UPF cooperatively processes the remaining data corresponding to the joint task identifier stored in the on-board UPF to obtain on-board processing data. The on-board UPF can fuse, calculate, or the like on the remaining data temporarily stored in the on-board UPF and belonging to the same joint task identifier.

[0070] Of course, other types of cooperative processing can also be performed, such as data splicing, aggregation and summarization, association alignment, deduplication, and the like, or even preliminary intelligent analysis using the computing power of the satellite, i.e., using the complementarity between multiple terminal data to perform inference and calculation that cannot be completed by a single terminal, such as triangular positioning, 3D reconstruction, federated learning, and the like. The exemplary embodiments of the present disclosure can select a corresponding cooperative processing mode according to actual scene requirements, and no specific limitation is made in this regard.

[0071] In some optional embodiments, a manner of determining the on-board UPF and the ground UPF is also provided, such as Figure 3 As shown, specifically includes:

[0072] Step S310: receiving, by a network access control function (NACF), a session establishment request sent by a terminal through a wireless access network, the terminal being any one of a plurality of terminals, and the session establishment request carrying a joint task identifier and a terminal identifier of the terminal.

[0073] The NACF (Network Access Control Function) is the first contact point of the terminal accessing the network, responsible for the identity authentication, authorization, and mobility management of the terminal, but does not process user plane data. The NACF receives a session establishment request and is responsible for selecting a suitable SMF (Session Management Function) for the session establishment request. The session establishment request is a signaling request initiated by the terminal to the network before the terminal needs to send service data, and the purpose is to establish a session (Session) channel for carrying data. For example, a PDU session establishment request.

[0074] In the example embodiment of the present disclosure, the request contains not only the conventional terminal identifier and network slice information, but also the most critical joint task identifier. This indicates that the session is not only a normal Internet access session, but also serves a specific collaborative task. The joint task subscription information is used to indicate whether the terminal participates in the joint task, and the specific participation information in the case of participating in the joint task, including the processing data type and / or multi-source data processing mode. The processing data type is, for example, image, video, etc., and the multi-source data processing mode includes one or more of multi-source data fusion, multi-temporal data fusion, etc.

[0075] Step S320: determining the target session management function (SMF) corresponding to the plurality of terminals by the NACF according to the joint task identifier, the terminal identifier and the joint task subscription information of the plurality of terminals.

[0076] The target SMF is the SMF instance selected by the NACF according to the policy for a specific session, which is responsible for managing the session. For all terminals of the same joint task, the NACF needs to ensure that they are allocated to the same target SMF to ensure the consistency of policy execution.

[0077] Specifically, the NACF sends a session management context request to the target SMF, and the session management context request carries the processing data type and / or multi-source data processing mode. Among them, the NACF selects the same SMF (for different UEs) supporting on-orbit data processing function according to the joint task identifier, the terminal identifier and the joint task subscription information of the plurality of terminals, that is, the target SMF, and sends the PDU session establishment session management context request to it, carrying the joint task subscription information, that is, the processing data type such as image, video, etc., and the data processing function (multi-source data processing mode) such as one or more of multi-source data fusion, multi-temporal data fusion, etc.

[0078] Step S330: determining the on-orbit UPF and the ground UPF by the target SMF based on the joint task identifier, the terminal identifier and the joint task subscription information.

[0079] Among them, the target SMF selects the same on-orbit UPF supporting data processing as the on-orbit UPF, and selects the same ground UPF supporting data processing as the ground UPF, and then the target SMF sends a session establishment or session modification request to the on-orbit UPF and the ground UPF respectively, and the control plane function information element carried in the session establishment or session modification request includes the support data processing information, so that the target SMF receives the response information of the on-orbit UPF and the ground UPF respectively, and the response information carries the data processing resource information.

[0080] Specifically, the support data processing information includes a processing data type and / or a multi-source data processing method, that is, the support data processing information needs to be added in a control plane function information element carried by a session establishment or session modification request, and contains a data processing type such as an image and a video, and a data fusion method for a joint task ID. The target SMF can send an N4 session establishment / modification request to the on-board UPF and the ground UPF respectively.

[0081] Each UPF returns response information to the target SMF, and carries a set of data processing resource information, including at least one of a processing data type, an available data processing amount, an available storage amount, and a multi-source data processing method.

[0082] In addition, the target SMF sends a session information transfer request to the NACF, and the session information transfer request carries the data processing resource information. Then, the NACF sends the data processing resource information to the terminal through a wireless access network. Accordingly, in the process of sending data, the terminal sends data that does not exceed the available storage amount indicated by the data processing resource information.

[0083] Figure 4 An interaction flowchart of session establishment and data sending of multi-terminal data in-orbit processing in a space-air-ground scene is shown. The following describes the multi-terminal data processing method of the example embodiment of the present disclosure. Figure 4 The multi-terminal data processing method of the example embodiment of the present disclosure is described.

[0084] Step S410: The remote sensing satellite sends a session establishment request through a wireless access network (such as a base station), and the session establishment request carries a joint task identifier and a terminal identifier of the terminal.

[0085] The base station forwards the message to the NACF.

[0086] First, the NACF determines target session management function SMFs corresponding to the plurality of terminals according to the joint task identifier, the terminal identifier, and joint task subscription information of the plurality of terminals.

[0087] The NACF selects the same target SMF supporting in-orbit data processing function (for different UEs) according to the UE identifier, the joint task ID in the PDU session establishment request, and judges that it needs to establish a session supporting in-orbit data processing according to its joint task subscription information, and sends a PDU session establishment session management context request to the target SMF, wherein the joint task subscription information of the terminal in-orbit data processing (such as one or more of a data processing type such as an image, a video, and a data processing function such as multi-source data fusion and multi-temporal data fusion) is carried.

[0088] Secondly, the target SMF selects the same on-board UPF supporting data processing as the on-board UPF, and selects the same ground UPF supporting data processing as the ground UPF.

[0089] Among them, for different remote sensing satellites (UE), the target SMF selects the same (for different UEs) ground UPF (deploys DPF or interacts with DPF) supporting data processing, and sends an N4 session establishment / modification request to it, wherein the control plane function information element carried needs to be increased. Data processing support information, including data processing types such as images, videos; data fusion methods for joint task ID, etc.

[0090] Correspondingly, for different remote sensing satellites (UE), the target SMF selects the same (for different UEs) on-board UPF (deploys DPF or interacts with DPF) supporting data processing, and sends an N4 session establishment / modification request to it, wherein the control plane function information element carried needs to be increased. Data processing support information, including data processing types such as images, videos; data fusion methods for joint task ID, etc.

[0091] Again, the on-board UPF and the ground UPF send response information to the target SMF, and the response information carries data processing resource information.

[0092] Among them, the data processing resource information includes at least one of the processing data type, the available data processing amount, the available storage amount, and the multi-source data processing method.

[0093] Next, the target SMF sends a session information transfer request to the NACF, and the session information transfer request carries the data processing resource information.

[0094] Further, the data processing resource information is sent to the terminal through the wireless access network by the NACF.

[0095] Among them, the terminal carries the joint task identifier when sending the to-be-processed data, and the to-be-processed data does not exceed the available storage amount indicated by the data processing resource information.

[0096] Finally, the on-board user plane function UPF receives the to-be-processed data sent by the terminal through the wireless access network, and the to-be-processed data carries the joint task identifier. The terminal is any one of a plurality of terminals corresponding to the joint task identifier.

[0097] Among them, the on-board UPF sends at least part of the data in the to-be-processed data to the ground UPF for processing to obtain ground processing data, and stores the remaining data of the to-be-processed data. The on-board UPF cooperatively processes the remaining data corresponding to the joint task identifier in the storage to obtain on-board processing data, and sends the on-board processing data to the ground UPF, so that the ground UPF forwards based on the ground processing data and the on-board processing data. That is, when the ground UPF receives data that has not been marked as processed, it stores and processes the data before forwarding; when receiving data packets marked as processed, it forwards directly.

[0098] It should be noted that the details of each step have been described in the above exemplary embodiments, and will not be repeated here.

[0099] According to the exemplary embodiments of the present disclosure, a multi-terminal data processing method is also provided, comprising:

[0100] The NACF receives a session establishment request sent by a terminal through a wireless access network, the terminal being any one of a plurality of terminals corresponding to the same task identification information, the session establishment request carrying a joint task identification and a terminal identification of the terminal;

[0101] The NACF determines target SMFs corresponding to the plurality of terminals according to the joint task identification, the terminal identification, and joint task subscription information of the plurality of terminals, so that the SMFs determine on-orbit UPFs and ground UPFs corresponding to the plurality of terminals;

[0102] The on-orbit UPFs and the ground UPFs are configured to cooperatively process to-be-processed data of the plurality of terminals according to the joint task identification.

[0103] It should be noted that the details have been described in the above exemplary embodiments, and will not be repeated here.

[0104] According to the exemplary embodiments of the present disclosure, a multi-terminal data processing method is also provided, comprising:

[0105] The terminal sends to-be-processed data to an on-orbit UPF through a wireless access network, the to-be-processed data carrying a joint task identification, the terminal being any one of a plurality of terminals corresponding to the joint task identification;

[0106] The on-orbit UPFs and the ground UPFs are configured to cooperatively process to-be-processed data of the plurality of terminals according to the joint task identification.

[0107] It should be noted that the details have been described in the above exemplary embodiments, and will not be repeated here.

[0108] The multi-terminal data processing method in the exemplary embodiments of the present disclosure, on the one hand, for the huge data obtained by the terminal, supports data processing through the on-board UPF, and further greatly reduces the amount of data that needs to be transmitted back to the ground station through on-orbit processing, effectively saves the communication bandwidth, and optimizes the utilization of resources. On the other hand, on-orbit processing can be performed immediately while data is being acquired, realizing the real-time nature of data processing, which is of great significance for some applications that require extremely high timeliness (such as disaster monitoring and early warning, military reconnaissance, etc.). The terminal can process remote sensing data in real time on orbit, quickly extract key information and send it to ground decision makers in a timely manner, providing timely and accurate basis for subsequent decision-making. For example, when a natural disaster such as a fire or flood occurs, the satellite can process remote sensing data in real time on orbit, quickly extract key information such as the scope and extent of the disaster area, and send it to ground decision makers in a timely manner, providing timely and accurate basis for emergency rescue and disaster response. Without the need to transmit a large amount of raw data back to the ground for processing, the waiting time for data transmission and ground station queuing processing is avoided, greatly shortening the entire task cycle from data acquisition to final information output, and improving the utilization efficiency and application value of remote sensing data. On the other hand, through the on-board UPF, data fusion and collaborative processing between multiple terminals can be realized, remote sensing data from different terminals can be integrated and analyzed in real time, the advantages of each terminal can be fully utilized, and more comprehensive and accurate information products can be generated. For example, on-orbit processing also helps to realize data fusion of satellites with aerial remote sensing, ground monitoring and other platforms. For example, remote sensing data after on-orbit processing can be fused and analyzed with data from ground weather stations, ocean buoys and other monitoring devices to form a comprehensive monitoring system integrating space and ground, and improve the monitoring accuracy and cognitive level of the earth's environment and resources.
