Communication methods, apparatus, systems, computer-readable storage media and program products

[0001] This application claims priority to Chinese Patent Application No. 202411998776.7, filed with the China National Intellectual Property Administration on December 31, 2024, entitled "Communication Method, Apparatus, System, Computer-Readable Storage Medium and Program Product", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, apparatus, system, computer-readable storage medium, and program product. Background Technology

[0003] With the continuous development of artificial intelligence (AI) technology, AI agents are being used more and more widely in various fields.

[0004] It is worth noting that different types of AI agents have significantly different computational power requirements when performing tasks. For some lightweight AI agents, their built-in computing resources are often insufficient for complex tasks with large data volumes. To address this limitation, some solutions allow AI agents to leverage the computing power provided by other devices to complete complex computational tasks.

[0005] However, the above solutions may pose a risk of leaking sensitive user data. Summary of the Invention

[0006] This application provides a communication method, apparatus, system, computer-readable storage medium, and program product that can effectively reduce the risk of artificial intelligence agents leaking sensitive user data.

[0007] In a first aspect, a communication method is provided, which can be executed by a first communication device. The first communication device may be a terminal (e.g., an artificial intelligence agent), or a device including a terminal, or a chip (or chip system) or other functional module capable of implementing the functions of the terminal, for example, the chip or functional module is disposed in the terminal.

[0008] For example, the communication method may include:

[0009] Determine the first processing method corresponding to the data to be processed; the first processing method includes scrambling processing based on channel noise and / or a first privacy algorithm;

[0010] Send first data to the second communication device; the first data is generated by processing the data to be processed according to the first processing method described above.

[0011] In this embodiment, when the first communication device has insufficient computing power, it scrambles the data to be processed based on channel noise and / or a first privacy algorithm, and then the second communication device performs further processing. This can not only complete some complex computing tasks, but also effectively avoid the leakage of sensitive user data.

[0012] In one possible implementation, the above method also includes:

[0013] The channel information is determined, and / or the first information corresponding to the data to be processed is determined; the first processing method is determined based on the channel information and / or the first information; the first information includes a first requirement and / or a second requirement corresponding to the data to be processed; the first requirement is used to indicate the privacy and security protection indicators of the data to be processed; the second requirement is used to indicate the availability level indicators of the data to be processed.

[0014] Through the above implementation, the first communication device evaluates whether channel noise and / or the first information of the data to be processed can be applied to scramble the data based on channel information and / or the first privacy algorithm. Based on the evaluation results, the first processing method can be accurately determined, so that the first data after scrambling can meet both the privacy and security protection indicators and the usability indicators.

[0015] In one possible implementation, when it is determined, based on channel information, that the result of scrambling the data to be processed with channel noise meets the first requirement, the first processing method includes scrambling the data to be processed based on channel noise.

[0016] With the above implementation method, when the result of scrambling the data to be processed using channel noise meets the first requirement, it is only necessary to use channel noise to scramble the data to be processed without further noise compensation. This simplifies the data processing process and reduces the power consumption of the first communication device.

[0017] In one possible implementation, when it is determined, based on channel information, that the result of scrambling the data to be processed using channel noise does not meet the second requirement, the first processing method includes scrambling the data to be processed based on a first privacy algorithm.

[0018] By implementing the above method, when the result of scrambling the data to be processed using channel noise does not meet the second requirement, only the first privacy algorithm is used to scramble the data to be processed, without using channel noise to scramble the data to be processed. This can prevent the availability of the first data after scrambling from being affected by large channel noise, so that the first data after scrambling can meet both the privacy and security protection indicators and the availability indicators.

[0019] In one possible implementation, when it is determined, based on channel information, that the result of scrambling the data to be processed using channel noise does not meet the first requirement, the aforementioned first processing method includes scrambling the data to be processed based on channel noise and a first privacy algorithm.

[0020] By implementing the above method, when the result of scrambling the data to be processed using channel noise does not meet the first requirement, the data to be processed is further scrambled based on the first privacy algorithm on the basis of scrambling the data to be processed using channel noise. This can avoid the situation where the privacy and security protection indicators cannot be achieved due to the low channel noise.

[0021] In one possible implementation, the above method also includes:

[0022] Send a first instruction message to the second communication device, the first instruction message being used to instruct the aforementioned first processing method.

[0023] The above implementation method ensures that the first communication device and the second communication device are synchronized in processing data, which helps the second communication device to correctly process the received first data.

[0024] In one possible implementation, when the first processing method includes scrambling the data to be processed based on the first privacy algorithm, the first indication information is also used to indicate the first privacy algorithm.

[0025] Through the above implementation, the second communication device can configure its own processing strategy based on the first privacy algorithm indicated by the first indication information, so as to match the scrambling processing mechanism used by the first communication device.

[0026] In one possible implementation, the above method also includes:

[0027] Receive a second instruction message from a second communication device, the second instruction message being used to indicate the aforementioned first processing method.

[0029] In one possible implementation, when the first processing method includes scrambling the data to be processed based on the first privacy algorithm, the second indication information is also used to indicate the first privacy algorithm.

[0030] Through the above implementation method, the first communication device can directly scramble the data to be processed based on the first privacy algorithm without having to determine the first privacy algorithm. This simplifies the processing flow of the first communication device and ensures the normal operation of the first communication device.

[0031] In one possible implementation, the aforementioned channel information includes at least one of the following: channel estimation information, noise estimation information, and channel state information; the method further includes:

[0124] The technical solution provided in this application will now be described with reference to the accompanying drawings.

[0125] To facilitate understanding of the embodiments of this application, the following points will be explained first:

[0126] First, in this application, the indication includes explicit indication (also known as direct indication) and implicit indication (also known as indirect indication). Explicit indication information A means including information A; implicit indication information A means indicating information A through the correspondence between information A and information B, and direct indication information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured; or it can refer to indicating information A through information B and preset rules.

[0127] Second, in this application, information C is used to determine information D, which includes both determining information D based solely on information C and determining it based on information C and other information. Furthermore, information C can also be used to determine information D indirectly, for example, in the case where information D is determined based on information E, and information E is determined based on information C.

[0128] Third, in this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the preceding and following related objects, but it does not exclude the possibility of indicating an "and" relationship; the specific meaning can be understood in context. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a and b and c. Here, a, b, and c can be single or multiple.

[0129] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, transmitted data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0130] The technical solutions provided in this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, sidelink (SL) communication systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5th Generation (5G) mobile communication systems, or new radio access technology (NR). Among these, 5G mobile communication systems can include non-standalone (NSA) and / or standalone (SA) networking. The technical solutions provided in this application can also be applied to future communication systems. This application does not limit the scope of these applications.

[0131] Figure 1 is a schematic diagram of the architecture of a communication system applicable to the communication method provided in this application. Figure 1 shows a schematic diagram of a possible, non-limiting system architecture. As shown in Figure 1, the communication system 100 includes a radio access network (RAN) 10 and a core network (CN) 20. Optionally, the communication system 100 also includes an Internet 30. RAN 10 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 10 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 20. The core network equipment in core network 20 and RAN node 110 in RAN 10 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0132] RAN10 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 5G mobile communication system, or a future-oriented evolution system. RAN10 can also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless-fidelity (Wi-Fi) system. RAN10 can also be a communication system that integrates two or more of the above systems.

[0133] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, is part of the communication system and helps terminals achieve wireless access. Multiple RAN nodes 110 in communication system 100 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 10 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0134] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node can be a macro base station (as shown in Figure 1, 110a), a micro base station or indoor station (as shown in Figure 1, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU).

[0135] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be separate entities or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0136] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0137] A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc.

[0138] In the embodiments of this application, the terminal and network device can be hardware devices, or software functions running on dedicated hardware, or software functions running on general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal and network device.

[0139] To better understand the technical solutions provided in the embodiments of this application, the terms involved in this application will be briefly explained below.

[0142] 2. Artificial General Intelligence (AGI)

[0143] AGI is machine intelligence that possesses general human intelligence and can perform any intellectual task that humans can perform. The goal is to enable machines to have broad cognitive abilities similar to humans, including understanding complex language, performing logical reasoning, solving new problems, learning and adapting to new environments, etc.

[0144] 3. Artificial Intelligence Agent

[0145] AI Agent is a system driven by a large model, possessing the ability to autonomously understand, perceive, plan, remember, and use tools, and can automatically execute software or hardware systems to complete complex tasks.

[0146] 4. Differential privacy (DP)

[0147] Differential privacy technology provides data security by introducing random perturbations into the data to protect privacy, achieving data usability without visibility. Differential privacy is mainly divided into local differential privacy (LDP) and centralized differential privacy technologies. Taking local differential privacy as an example, the terminal can add noise (perturbation) to the uploaded raw data, thus preventing server nodes from obtaining user privacy information. Optionally, the methods for adding noise include: Laplace's law, exponential law, random response law, Gaussian law, etc.

[0148] Currently, generative AI technology based on large models is developing rapidly, and AI agents based on large models represent the cutting-edge development trend and application direction of AGI. AI agents not only make it possible for everyone to have virtual intelligent agents (such as digital humans, intelligent assistants, etc.), but will also bring a large number of embodied intelligent agents (such as humanoid robots, robot dogs, intelligent cars, intelligent drones, etc.) into people's lives and work.

[0149] In the face of the development of artificial intelligence agents, the capabilities of mobile communication networks will expand from providing wider network coverage, higher connection bandwidth, and lower transmission latency to enabling various artificial intelligence agents to interconnect anytime and anywhere, realizing cross-ecosystem information interaction and task collaboration among artificial intelligence agents, and empowering artificial intelligence agents by utilizing the network's inherent AI, perception, and computing capabilities, thereby bringing a qualitative leap to people's lives and work in terms of intelligent experience.

[0150] Artificial intelligence agents require a certain amount of computing power to perform tasks. The computing power requirements vary significantly depending on the type of AI agent and the task being performed. For lightweight terminal devices such as smartphones, extended reality (XR) glasses, and drones, the computing power is usually insufficient to support complex computational tasks.

[0151] In response to the inherent limitations of AI agents in terms of computing power, some implementations can deploy computing power at the network edge or within the network, allowing AI agents to utilize this power to complete complex computational tasks.

[0152] For example, computing resources can be deployed on RAN nodes to provide the necessary computing power for the AI ​​agent. The AI ​​agent can send data related to the computing task to the RAN node, which will then perform further computational processing, such as using AI inference technology to analyze user behavior. The RAN node will then feed back the processing results to the AI ​​agent, which can then perform corresponding operations based on the received results.

[0153] In practical applications, in order to better serve users, AI agents may collect a large amount of sensitive user data (such as user location data, environmental data, call data, etc.) for reasoning and decision-making. If the AI ​​agent sends this data to the RAN node, there may be a risk of leakage of sensitive user data.

[0154] To address the aforementioned technical issues, this application provides a communication method in which an artificial intelligence agent can perform privacy protection processing on user data that needs to be sent to the RAN node, thereby achieving the effect of user data being usable but invisible and reducing the risk of user privacy leakage.

[0155] The communication methods provided in the various embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0156] In some embodiments, the communication method provided in this application can be executed by a communication device. On the terminal side, the communication device can be a terminal (e.g., the aforementioned artificial intelligence agent), or a device including a terminal, or a chip (or chip system) or other functional module capable of implementing the terminal's functions; for example, the chip or functional module is disposed in the terminal. On the network side, the communication device can be a network device, or it can be executed by a chip (or chip system) or other functional module capable of implementing the network device's functions; for example, the chip or functional module is disposed in the network device. Optionally, the network device can be an access network device, a core network device, or a third-party device, without limitation. The following description uses a first communication device and a second communication device as examples.

[0157] Optionally, the first communication device described above belongs to the terminal side, and the terminal can be of any form, such as a home or personal smart terminal, a personal wearable device, an industrial smart device, a smart car, an artificial intelligence agent, etc., and there is no limitation in this application embodiment. The second communication device described above belongs to the network device, and the network device can also be of any form, such as a RAN node, a base station, an artificial intelligence agent, a cloud server, an edge server, etc., and there is also no limitation in this application embodiment.

[0158] For example, referring to Figure 2, which is a flowchart illustrating a communication method provided in an embodiment of this application. In some embodiments of this application, the communication method shown in Figure 2 may include steps 210 and 220, and the various steps in this communication method are described in detail below.

[0159] S210, the first communication device determines the first processing method corresponding to the data to be processed; the first processing method includes scrambling processing based on channel noise and / or a first privacy algorithm.

[0160] In some implementations, when the first communication device performs certain specific tasks (such as AI calculations), it can collect or acquire data related to the task through various means (such as built-in sensors, communication networks, etc.) and treat this data as data to be processed.

[0161] Optionally, the data to be processed may include one or more data types, such as text, images, videos, audio, location information, etc.

[0162] Optionally, the data to be processed may include one or more data categories, for example, it may include:

[0163] User interaction data includes data collected by the primary communication device during interaction with the user, such as user input data (text, voice, images, etc.), user click behavior data, and browsing history data. This data can help understand user behavior patterns and preferences.

[0164] User location information: User location data obtained through location technology. This data is crucial for providing location-based services (such as navigation, nearby business recommendations, etc.).

[0165] User Personal Information: With the user's authorization, the first communication device may collect the user's personal information, such as name, age, gender, and occupation. This information helps in creating user profiles and personalized recommendations.

[0166] Environmental data: The first communication device can collect data on the user's current physical environment, such as images, noise, temperature, and humidity, through sensors (e.g., cameras, microphones, temperature sensors). This data helps to perceive and understand the user's environment, thereby enabling smarter decision-making.

[0167] Transaction data, such as purchase records and payment records, helps analyze user spending behavior and purchasing preferences, thereby optimizing marketing strategies and product design.

[0168] In some implementations, the data to be processed may only include the data in the data packet payload, and the data in the data packet header does not need to be processed according to the first processing method described above. For example, the data packet header can be processed and transmitted using existing communication mechanisms.

[0169] After determining the data to be processed, the first processing method corresponding to the data to be processed can be determined.

[0170] In some embodiments, the first processing method described above can be scrambling the data to be processed based solely on channel noise. Since channel noise is inherently random and unpredictable, it can be an effective scrambling technique. By introducing channel noise into the data to be processed, the complexity and randomness of the data can be increased, thereby achieving a certain degree of data privacy protection.

[0171] Optionally, channel noise can be modeled as Gaussian noise (a type of noise that follows a Gaussian distribution). In scrambling, the characteristics of Gaussian noise can be used to generate scrambling noise. For example, by simulating the distribution of Gaussian noise, a random noise sequence of the same length as the data to be processed can be generated and superimposed on the data to be processed, thereby achieving data scrambling.

[0172] In some implementations, when it is determined that scrambling of the data to be processed is based solely on channel noise, the first communication device may not need to perform verification-related operations on the data to be processed. For example, it may not be necessary to add redundant bits to the data to be processed, thereby simplifying the processing operations of the first communication device and improving its efficiency and reliability.

[0173] In some embodiments, the first processing method described above may also be to scramble the data to be processed based solely on the first privacy algorithm.

[0174] In some implementations, artificial noise can be generated using the first privacy algorithm described above, and the generated artificial noise can be used to scramble the data to be processed.

[0175] Optionally, the first privacy algorithm mentioned above can be a differential privacy algorithm, and this application embodiment does not impose any restrictions.

[0176] In some implementations, when it is determined that the data to be processed is scrambled only based on the first privacy algorithm, the first communication device may perform verification-related operations on the scrambled data to be processed.

[0177] In some embodiments, the first processing method described above may also be to simultaneously scramble the data to be processed using channel noise and a first privacy algorithm.

[0178] In some implementations, artificial noise generated by a first privacy algorithm can be used to perform preliminary scrambling on the data to be processed. Then, during the transmission of the data to be processed, channel noise can be used to further scramble the data.

[0179] S220, the first communication device sends first data to the second communication device; the first data is generated by processing the data to be processed according to the first processing method.

[0180] In some implementations, the first communication device can upload the data to be processed to the second communication device.

[0181] Optionally, when the first processing method involves scrambling based solely on channel noise, the first communication device sends the data to be processed to the second communication device. During the transmission of this data, channel noise is applied to scramble it. Correspondingly, the second communication device receives first data sent by the first communication device, which is generated after the data to be processed has undergone channel noise scrambling.

[0182] When the first processing method described above involves scrambling based solely on the first privacy algorithm, the first communication device can generate artificial noise using the first privacy algorithm, and then use the generated artificial noise to scramble the data to be processed, generating first data, which is then sent to the second communication device. Correspondingly, the second communication device receives the first data sent by the first communication device.

[0183] When the first processing method involves scrambling the data with channel noise based on the first privacy algorithm, the first communication device can generate artificial noise using the first privacy algorithm and use the generated artificial noise to scramble the data to be processed, generating intermediate data. This intermediate data is then sent to the second communication device. During the transmission of this intermediate data, channel noise is applied to scramble it. Correspondingly, the second communication device receives first data sent by the first communication device, which is generated from the intermediate data after channel noise scrambling.

[0184] In some implementations, when the second communication device receives the first data sent by the first communication device, it can use the first data for corresponding processing or analysis, such as training a machine learning model, data mining, statistical analysis, etc., which are not limited in the embodiments of this application.

[0185] Understandably, because the first data has undergone scrambling, it ensures that, on the one hand, the first data is not easily intercepted and parsed during transmission, and even if the first data is intercepted, the attacker cannot directly obtain the original data. On the other hand, when the first data reaches the second communication device, even if the second communication device is compromised, the attacker will find it difficult to directly obtain useful information from the data stored in the second communication device, thus achieving the goal of making the first data usable but invisible.

[0186] In some implementations, when the second communication device receives the first data, it can use the existing parsing mechanism to parse the data packet header.

[0187] The communication method provided in this application embodiment allows the first communication device to scramble the data to be processed based on channel noise and / or a first privacy algorithm when its own computing power is insufficient, and then send it to the second communication device for further processing. This not only enables the completion of some complex computing tasks, but also effectively avoids the leakage of sensitive user data.

[0188] For example, referring to Figure 3, Figure 3 is a schematic flowchart of a communication method provided in an embodiment of this application. In some embodiments of this application, the communication method shown in Figure 3 may include:

[0189] S310, The first communication device determines the channel information and / or determines the first information corresponding to the data to be processed.

[0190] Optionally, the aforementioned channel information includes at least one of the following: channel estimation information, noise estimation information, and channel state information (CSI).

[0191] In some implementations, the first communication device can acquire channel condition information, such as CSI. CSI is a parameter describing the state of a wireless channel; it describes the signal attenuation factor on each transmission path, i.e., the value of each element in the channel gain matrix H.

[0192] In some embodiments, the first communication device may send a request message to the second communication device for obtaining channel estimation information and / or noise estimation information. Correspondingly, upon receiving the request message from the first communication device, the second communication device may send third data to the first communication device, the third data including the aforementioned channel estimation information and / or noise estimation information.

[0193] Optionally, the channel estimation information mentioned above includes channel estimation methods, such as least squares (LS) and minimum mean squared error (MMSE).

[0194] Optionally, the noise estimation information mentioned above may include information such as the distribution, mean, and variance of channel noise. The first communication device can use the received noise estimation information to better understand the noise situation in the current communication environment.

[0195] Optionally, the aforementioned first information includes a first requirement and / or a second requirement corresponding to the data to be processed; the first requirement is used to indicate the privacy and security protection indicators of the data to be processed; and the second requirement is used to indicate the availability indicators of the data to be processed.

[0196] In some implementations, privacy protection metrics for the data to be processed can be used to measure the degree of privacy protection. For example, the privacy loss (∈,δ) parameter can be used to define the privacy protection metric for the data to be processed. When the privacy loss ∈ is small, even if a record in the data changes, the output distribution of the privacy algorithm will not change significantly, thus protecting individual privacy. The smaller the ∈ value, the higher the degree of privacy protection, but the usability (accuracy) of the data may decrease.

[0197] In some implementations, availability metrics for the data to be processed can be used to measure the reliability and effectiveness of the data in a specific application scenario, thereby ensuring that the data meets business needs and generates real value. For example, utility requirements can be used to define availability metrics for the data to be processed.

[0198] In some implementations, the first information may also include the data type and / or encoding method corresponding to the data to be processed.

[0199] In some implementations, the first communication device may obtain the aforementioned first information from the application layer.

[0200] Optionally, the application layer can directly indicate the first information to the access stratum (AS) of the first communication device. Alternatively, the first communication device can obtain the first information from the application layer through the core network. Or, the first communication device can obtain the first information from the application layer through the RAN.

[0201] S320. The first communication device determines the first processing method corresponding to the data to be processed based on the aforementioned channel information and / or first information.

[0202] In some embodiments, when the first communication device determines, based on channel information, that the result of scrambling the data to be processed with channel noise meets the first requirement, the first processing method may include scrambling the data to be processed with channel noise.

[0203] In some embodiments, when the first communication device determines, based on channel information, that the result of scrambling the data to be processed using channel noise does not meet the second requirement, the first processing method may include scrambling the data to be processed based on a first privacy algorithm.

[0204] In some embodiments, when the first communication device determines, based on channel information, that the result of scrambling the data to be processed using channel noise does not meet the first requirement, the first processing method may include scrambling the data to be processed based on channel noise and a first privacy algorithm.

[0205] In this embodiment, the first communication device can evaluate whether channel noise and / or a first privacy algorithm can be applied to scramble the data to be processed based on channel information and / or first information of the data to be processed. Based on the evaluation results, the first processing method can be accurately determined so that the first data after scrambling can meet both the privacy and security protection indicators and the usability indicators.

[0206] For example, the first communication device can assess the feasibility of applying channel noise to scramble the data to be processed based on channel information and / or the aforementioned first information, such as assessing whether the result of applying channel noise to scramble the data to be processed meets the aforementioned first requirement.

[0207] Channel noise often depends on communication conditions. The channel noise of the first communication device follows a specific distribution, but this specific distribution may not meet privacy and security protection indicators or may exceed data availability indicators, potentially causing performance to fail to meet application requirements. For example, if the channel noise is too high, it may lead to significant information loss after data scrambling, resulting in poor accuracy of AI calculations and inferences; if the channel noise is too low, it may lead to the risk of data privacy leakage.

[0208] If the result of scrambling the data to be processed using channel noise meets the first requirement mentioned above, it means that the data to be processed can be scrambled using only channel noise without further noise compensation, thereby simplifying the data processing process and reducing the power consumption of the first communication device.

[0209] If the result of scrambling the data to be processed using channel noise does not meet the first requirement mentioned above, it indicates that the current channel noise is relatively low. Scrambling the data to be processed using only channel noise cannot achieve the privacy and security protection index of the data to be processed. Therefore, in addition to scrambling the data to be processed using channel noise, the data to be processed can be further scrambled based on the first privacy algorithm. This can avoid the situation where the privacy and security protection index cannot be achieved due to the low channel noise.

[0210] In addition, the first communication device can also evaluate, based on channel information and / or the aforementioned first information, whether the result of scrambling the data to be processed with channel noise meets the aforementioned second requirement.

[0211] If the result of scrambling the data to be processed using channel noise meets the second requirement mentioned above, it means that channel noise can be used to scramble the data to be processed. In this case, only channel noise can be used to scramble the data to be processed without further noise compensation. Alternatively, in addition to scrambling the data to be processed using channel noise, the data to be processed can be scrambled using the first privacy algorithm. This application does not impose any restrictions on this embodiment.

[0212] If the result of scrambling the data to be processed using channel noise does not meet the second requirement mentioned above, it indicates that the current channel noise is too high. If channel noise is used to scramble the data to be processed, it will affect the usability of the first data after scrambling, and the usability index of the data to be processed cannot be achieved. Therefore, in this case, only the first privacy algorithm is used to scramble the data to be processed, without using channel noise to scramble the data to be processed.

[0213] In some implementations, when the first processing method includes scrambling based on a first privacy algorithm, the first communication device may generate artificial noise according to the first privacy algorithm and use the artificial noise to scramble the data to be processed.

[0214] In some implementations, the first privacy algorithm described above can be a differential privacy algorithm, the implementation of which includes two core elements:

[0215] I. Noise Mechanisms: Privacy is protected by adding random noise to the data. Common noise mechanisms include Laplace noise and Gaussian noise. Laplace noise provides strict differential privacy, while Gaussian noise provides relaxed differential privacy.

[0216] Second, privacy budgeting quantifies the strength of privacy protection. By setting a privacy budget parameter, the risk of privacy leaks during data use can be controlled. The smaller the privacy budget parameter, the greater the noise, the lower the usability of the results, and the better the privacy protection effect.

[0217] In some implementations, a differential privacy algorithm can be determined first, including selecting a noise mechanism and privacy budget parameters. Then, based on the selected noise mechanism and privacy budget parameters, the noise to be added can be determined. Finally, the determined noise is added to the data to be processed to obtain the scrambled first data.

[0218] In some implementations, the first communication device may also predetermine which protocol layer's data will be scrambled. For example, scrambling may be performed on packet data convergence protocol (PDCP) protocol data units (PDUs).

[0219] PDCP is a protocol layer in LTE and 5G NR networks, located above the radio link control (RLC) layer and below the internet protocol (IP) layer. The main function of the PDCP layer is to provide services such as packet data transmission, header compression, encryption, and decryption, ensuring efficient and secure data transmission over the radio interface.

[0220] It is understood that the specific content of step S330 can also refer to the content of step S210 in the above embodiment, and will not be repeated here.

[0221] S330, the first communication device sends a first instruction message to the second communication device, the first instruction message being used to indicate the aforementioned first processing method.

[0222] In some implementations, after the first communication device determines the first processing method, it can send a first instruction message to the second communication device. Accordingly, when the second communication device receives the first instruction message, it can determine, based on the first instruction message, what processing method the first communication device used to process the data to be processed.

[0223] Optionally, the first indication information may be used only to indicate whether channel noise is applied for scrambling.

[0224] For example, the first indication information may include an indication field. When the value of the indication field is a first value (e.g., "1"), the first indication information may be used to indicate that the first processing method includes applying channel noise for scrambling. When the value of the indication field is a second value (e.g., "0"), the first indication information may be used to indicate that the first processing method does not apply channel noise for scrambling.

[0225] The above implementation method can ensure that the first communication device and the second communication device are synchronized in processing data, which helps the second communication device to correctly process the received first data.

[0226] In some implementations, when the first processing method includes scrambling the data to be processed based on a first privacy algorithm, the first indication information is also used to indicate the first privacy algorithm.

[0227] Optionally, the first indication information may include the identifier of the first privacy algorithm (such as the algorithm's name, version number, specific parameter configuration, etc.) so that the second communication device can accurately identify and understand the noise generation mechanism used by the first communication device.

[0228] Through the above implementation method, the second communication device can configure its own processing strategy based on the first privacy algorithm indicated by the first indication information, so as to match the scrambling processing mechanism used by the first communication device.

[0229] S340, the first communication device sends first data to the second communication device. This first data is generated by processing the data to be processed according to the first processing method described above.

[0230] In some implementations, the first communication device sends first data to the second communication device, and the second communication device receives the first data sent by the first communication device and uses the first data for corresponding processing or analysis.

[0231] In some implementations, when the first processing method includes scrambling the data to be processed based on channel noise, the second communication device may disable the preset operation.

[0232] Optionally, the above-mentioned preset operations include noise reduction processing and / or cyclic redundancy check on the received first data.

[0233] In some implementations, when the first processing method is to scramble the data to be processed based solely on the first privacy algorithm, the second communication device may not need to disable the preset operation.

[0234] Understandably, in scrambling based on channel noise, noise is no longer a negative factor that needs to be eliminated, but rather becomes part of the encryption mechanism. Therefore, when the second communication device receives the scrambled first data, it may not perform noise reduction processing to avoid compromising the encryption effect of the first data.

[0235] In addition, in scrambling based on channel noise, since the first data has already been encrypted, cyclic redundancy check may not be directly applied to the scrambled first data, so it can also be disabled to reduce the computing power consumption of the second communication device.

[0236] It should be noted that there is no sequential relationship between steps S330 and S340. That is, the first communication device may send the first instruction information to the second communication device first, and then send the first data to the second communication device; or, it may send the first data to the second communication device first, and then send the first instruction information to the second communication device; or, it may send the first data and the first instruction information to the second communication device simultaneously. No restrictions are imposed in this embodiment.

[0237] In some implementations, after receiving the first data sent by the first communication device, the second communication device can use the first data to perform corresponding processing or analysis, such as training a machine learning model, data mining, statistical analysis, etc., to obtain processing or analysis results, and then feed back the processing or analysis results to the first communication device. After receiving the processing or analysis results, the first communication device can execute corresponding operations or generate corresponding execution instructions.

[0238] The communication method provided in this application embodiment allows the first communication device to determine the first processing method based on channel information and the first information corresponding to the data to be processed when its own computing power is insufficient. Then, based on the first processing method, it sends the first data to the second communication device for further processing. This not only completes some complex computing tasks, but also effectively avoids the leakage of sensitive user data.

[0239] In some embodiments, the steps performed by the first communication device can be performed by the application layer; or by any protocol layer in the AS layer; or by a single module in the first communication device (hereinafter referred to as the second module).

[0240] For example, referring to Figure 4, which is a schematic diagram of the architecture of a first communication device provided in an embodiment of this application.

[0241] In some implementations, the second module can obtain the first information corresponding to the data to be processed from the application layer.

[0242] In some implementations, the second module may request channel state information from the AS side by requesting channel information such as channel estimation information and / or noise estimation information from the second communication device.

[0243] In some implementations, the second module can trigger the first communication device to send a request message to the second communication device by sending a request to the AS layer, requesting to obtain channel estimation information and / or noise estimation information.

[0244] In some implementations, after determining that the application channel noise has been scrambled, the second module can determine whether the first privacy algorithm needs to be applied for scrambling compensation based on the noise estimation information and the privacy and security requirements of the application layer.

[0245] If it is determined that a first privacy algorithm is needed for scrambling compensation, the second module, after determining the first privacy algorithm, can instruct the AS layer to perform scrambling on the data to be processed. Optionally, the first privacy algorithm can be used to scramble data from any protocol layer (such as PDCP PDU).

[0246] In some implementations, the second module may also instruct the first privacy algorithm to the application layer, which will then perform scrambling compensation. This application does not impose restrictions on where the scrambling compensation is performed.

[0247] In some implementations, if the second module determines that channel noise is applied for scrambling, it is also necessary to instruct the AS layer to generate first indication information and send the first indication information to the second communication device. The first indication information is used to instruct the first communication device to apply channel noise to scramble the data to be processed.

[0248] In some implementations, the first communication device may scramble only the payload of the data to be processed, while the header is still transmitted using the existing communication mechanism. This can reduce processing time and computational resource consumption, while also reducing the occupation of transmission bandwidth.

[0249] In some implementations, the application layer can scramble the data to be processed, while the AS layer still uses the existing mechanism for transmission. In this case, the second module can be deployed in the application layer of the first communication device.

[0250] Referring to Figure 5, which is a schematic flowchart of a communication method provided in an embodiment of this application, in some embodiments of this application, the communication method shown in Figure 5 may include:

[0251] S510, the second communication device determines the channel information and / or determines the first information corresponding to the data to be processed.

[0252] Optionally, the aforementioned channel information includes at least one of the following: channel estimation information, noise estimation information, and channel state information.

[0253] In some implementations, the second communication device can acquire channel measurement information (such as CSI) reported by the first communication device for channel estimation and noise estimation.

[0254] Optionally, the channel estimation information mentioned above includes channel estimation methods, such as least squares method, minimum mean square error, etc.

[0255] Optionally, the noise estimation information mentioned above may include information such as the distribution, mean, and variance of channel noise.

[0256] In some implementations, the second communication device may acquire application layer indication information, which includes the aforementioned first information.

[0257] Optionally, the second communication device can obtain the aforementioned application layer instruction information through information reported by the first communication device or through core network instructions.

[0258] Optionally, the aforementioned first information includes a first requirement and / or a second requirement corresponding to the data to be processed; the first requirement is used to indicate the privacy and security protection indicators of the data to be processed; and the second requirement is used to indicate the availability indicators of the data to be processed.

[0259] In some implementations, the first information may also include the data type and / or encoding method corresponding to the data to be processed.

[0260] S520. The second communication device determines the first processing method corresponding to the data to be processed based on the aforementioned channel information and / or the first information.

[0261] In some embodiments, when the second communication device determines, based on channel information, that the result of scrambling the data to be processed with channel noise meets the first requirement, the first processing method includes scrambling the data to be processed based on channel noise.

[0262] In some embodiments, when the second communication device determines, based on channel information, that the result of scrambling the data to be processed using channel noise does not meet the second requirement, the first processing method may include scrambling the data to be processed based on a first privacy algorithm.

[0263] In some embodiments, when the second communication device determines, based on channel information, that the result of scrambling the data to be processed with channel noise does not meet the first requirement, the first processing method may include scrambling the data to be processed based on channel noise and a first privacy algorithm.

[0264] In this embodiment, the second communication device can evaluate whether channel noise and / or a first privacy algorithm can be applied to scramble the data to be processed based on channel information and / or the first information of the data to be processed. Based on the evaluation results, the first processing method can be accurately determined so that the first data after scrambling can meet both the privacy and security protection indicators and the usability indicators.

[0265] For example, the second communication device can assess the feasibility of applying channel noise to scramble the data to be processed based on channel information and / or the first information mentioned above, such as assessing whether the result of applying channel noise to scramble the data to be processed meets the first requirement mentioned above.

[0266] If the result of scrambling the data to be processed using channel noise meets the first requirement mentioned above, it means that the data to be processed can be scrambled using only channel noise without further noise compensation, thereby simplifying the data processing process of the first communication device.

[0267] If the result of scrambling the data to be processed using channel noise does not meet the first requirement mentioned above, it indicates that the current channel noise is relatively low. Scrambling the data to be processed using only channel noise cannot achieve the privacy and security protection index of the data to be processed. Therefore, in addition to scrambling the data to be processed using channel noise, the data to be processed can be further scrambled based on the first privacy algorithm. This can avoid the situation where the privacy and security protection index cannot be achieved due to the low channel noise.

[0268] In addition, the second communication device can also evaluate, based on channel information and / or the aforementioned first information, whether the result of scrambling the data to be processed with channel noise meets the aforementioned second requirement.

[0269] If the result of scrambling the data to be processed using channel noise meets the second requirement mentioned above, it means that channel noise can be used to scramble the data to be processed. In this case, only channel noise can be used to scramble the data to be processed without further noise compensation. Alternatively, in addition to scrambling the data to be processed using channel noise, the data to be processed can be scrambled using the first privacy algorithm. This application does not impose any restrictions on this embodiment.

[0270] If the result of scrambling the data to be processed using channel noise does not meet the second requirement mentioned above, it indicates that the current channel noise is too high. If channel noise is used to scramble the data to be processed, it will affect the usability of the first data after scrambling, and the usability index of the data to be processed cannot be achieved. Therefore, in this case, only the first privacy algorithm is used to scramble the data to be processed, without using channel noise to scramble the data to be processed.

[0271] S530, the second communication device sends a second instruction message to the first communication device, the second instruction message being used to indicate the aforementioned first processing method.

[0272] In some implementations, after the second communication device determines the first processing method, it can send second instruction information to the first communication device. Accordingly, when the first communication device receives the second instruction information, it can determine the first processing method based on the second instruction information.

[0273] Optionally, the second indication information may be used only to indicate whether scrambling processing is applied using channel noise and / or the first privacy algorithm.

[0274] For example, the second indication information may include an indication field. When the value of the indication field is a first value (e.g., "10"), the second indication information may be used to indicate that the first processing method includes scrambling processing with channel noise. When the value of the indication field is a second value (e.g., "01"), the second indication information may be used to indicate that the first processing method includes scrambling processing with a first privacy algorithm. When the value of the indication field is a third value (e.g., "11"), the second indication information may be used to indicate that the first processing method includes scrambling processing with both channel noise and a first privacy algorithm.

[0275] In some implementations, when the first processing method includes scrambling the data to be processed based on a first privacy algorithm, the second indication information is also used to indicate the first privacy algorithm.

[0276] Optionally, when the first processing method includes scrambling the data to be processed based on the first privacy algorithm, the second communication device can determine the first privacy algorithm and use the second indication information to indicate the first privacy algorithm to the first communication device.

[0277] Optionally, the second instruction information may include the identifier of the first privacy algorithm (such as the algorithm's name, version number, specific parameter configuration, etc.) so that the first communication device can accurately identify it.

[0278] Alternatively, when the first processing method includes scrambling the data to be processed based on the first privacy algorithm, the second communication device may use only the second indication information to instruct the first communication device that the first processing method includes scrambling the data to be processed based on the first privacy algorithm, and the first communication device shall determine the first privacy algorithm.

[0279] In some implementations, when the first processing method includes scrambling based on a first privacy algorithm, the first communication device may generate artificial noise according to the first privacy algorithm and use the artificial noise to scramble the data to be processed.

[0280] In some implementations, the first privacy algorithm described above may be a differential privacy algorithm.

[0281] S540, the first communication device sends first data to the second communication device. This first data is generated by processing the data to be processed according to the first processing method described above.

[0282] In some implementations, the first communication device sends first data to the second communication device, and the second communication device receives the first data sent by the first communication device and uses the first data for corresponding processing or analysis.

[0283] In some implementations, when the first processing method includes scrambling the data to be processed based on channel noise, the second communication device may disable the preset operation.

[0284] Optionally, the above-mentioned preset operations include noise reduction processing and / or cyclic redundancy check on the received first data.

[0285] In some implementations, when the first processing method is to scramble the data to be processed based solely on the first privacy algorithm, the second communication device may not need to disable the preset operation.

[0286] In some implementations, after receiving the first data sent by the first communication device, the second communication device can use the first data to perform corresponding processing or analysis, such as training a machine learning model, data mining, statistical analysis, etc., to obtain processing or analysis results, and then feed back the processing or analysis results to the first communication device. After receiving the processing or analysis results, the first communication device can execute corresponding operations or generate corresponding execution instructions.

[0287] The communication method provided in this application embodiment involves a second communication device determining a first processing method based on channel information and first information corresponding to the data to be processed, and instructing the first processing method to the first communication device. The first communication device then performs scrambling processing on the data to be processed based on the first processing method, thereby making the data visible but unusable and effectively preventing the leakage of sensitive user data.

For example, the CU can indicate the aforementioned first information and channel state information, and the DU can indicate channel estimation information and / or noise estimation information. Alternatively, the CU can first obtain the channel estimation information and noise estimation information from the DU, and then send the aforementioned first information, channel state information, channel estimation information, and noise estimation information together to the aforementioned network element device.

[0298] In some implementations, the first module described above can be used to perform steps S520 and S530 described above.

[0299] Optionally, if the first module is located in the DU, the DU instructs the first processing method described above to the CU, and the CU generates the second instruction information described above and sends it to the first communication device.

[0310] In some embodiments, in a RAN intelligent controller (RIC) architecture communication system, the RIC includes near-real-time RIC (near-RT RIC) and non-real-time RIC (non-RT RIC).

[0311] In some implementations, near real-time RIC is used for model training and inference. For example, it is used to train an AI model and then use that AI model for inference.

[0312] Near real-time RIC can obtain information from a second communication device (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or a first communication device. This information can be used as training data or inference data. Optionally, the near real-time RIC can pass the inference results to the second communication device and / or the first communication device.

[0313] Optionally, inference results can be exchanged between CU and DU, and / or between DU and RU. For example, near real-time RIC submits inference results to DU, and DU sends them to RU.

[0314] In some implementations, non-real-time RICs can be used for model training and inference. For example, they can be used to train an AI model and then use that model for inference.
