[0024] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0025] like Figure 1a As shown, it is a schematic diagram of a communication network architecture provided by the present application, which is a minimalist, distributed, autonomous, highly cohesive, low-coupled future network architecture (also known as 6G communication network architecture, etc.), which is a data-centric design, and network capabilities are developed around data, which can meet the requirements of future networks, such as perception, AI and other new capabilities and new data services.

[0026] In this embodiment, the communication network architecture may include but is not limited to one or more of a network control unit (NCU), a network packet processing unit (NPU), a network data unit (NDU), a network intelligent unit (NIU), etc., and the NCU, NPU, NIU, and NDU correspond to the control plane, user plane, intelligent plane, and data plane of the communication network architecture, respectively, which can improve the problems of a large number of network elements and complex signaling in the existing communication network architecture, realize a flexible and customizable network, and enable future human-machine-object virtual global service innovation. It can be understood that the naming of each network unit in the communication network architecture provided in this application can be but is not limited to the aforementioned NCU, NPU, NIU, NDU, etc., that is, the naming of each network unit in the communication network architecture provided in this application can be flexibly designed according to communication standards or protocols, etc. In addition, the communication network architecture may include one or more identical network elements (such as NDU, etc.), which are not limited here.

[0027] In this case, each network element in the aforementioned communication network architecture will first be introduced below.

[0028] NCU: The NCU is the network control center in the communication network architecture, and is used to provide network control related functions, including but not limited to mobility management, session management, and other extended functions, such as deterministic communication, computing network collaboration, and inter-sensory integration; it is also responsible for driving tasks, completing the collaboration of connection, computing power, intelligence, perception, and other tasks.

[0029] NPU: The NPU is used to provide network packet forwarding related functions. For example, it can inherit the basic functions of user-plane data forwarding in related communication network architectures (such as 5G network architecture, 4G network architecture, etc.), and introduce user-plane programmable functions to achieve the purpose of flexibly defining the processing logic of the user plane, while evolving towards functional characteristics such as computing network service perception, deterministic communication, and fine-grained subnets.

[0030] NIU: The NIU is used to provide intelligent endogenous related functions, such as artificial intelligence (AI) task scheduling management, online reasoning, online training, knowledge model warehouse and other functions, as well as cross-layer and cross-domain intelligence between multiple nodes through distributed learning collaboration, internal network simplification, elasticity and intelligence, and flexible AI services for external applications.

[0031] NDU: The NDU is used as an independent data plane to provide data management related functions, such as integrating (or aggregating) and processing the Unified Data Repository (UDR) and Unstructured Data Storage Function (UDSF) by NDU to form an independent data plane.

[0032] In one implementation, the NDU may also have the following characteristics.

[0033] (a) NDU can separate data from business, reduce the coupling between data processing and business processing, provide consistent services for data security, management, and access, and open up data service capabilities to the outside world through standardized interfaces.

[0034] (b) In NDU, data is classified, designed, stored, aggregated, and processed, and network capabilities are developed around data, so that the system has stronger data integrity and consistency, and it is easy to use professional data storage and access technologies to achieve consistency and simplification of data processing logic.

[0035] (c) NDU can complete the unified storage and management of various data, reduce data redundancy, reduce storage resource usage and network resource overhead, and avoid data consistency issues.

[0036] (d) NDU integrates the original multiple data interactions, simplifies the signaling and merges the data to obtain and update the required data at one time.

[0037] (e) The NDU retains and enhances the UDR and UDSF in relevant communication network architectures (such as 5G network architecture, 4G network architecture, etc.), adds a file interface, and provides support for efficient transmission of directories and files; adds interfaces such as Remote Direct Memory Access (RDMA) to provide support for efficient transmission of block data.

[0038] (f) NDU defines a self-explanatory and self-executing framework for customizing 5G data models, which can adapt to interoperability among different manufacturers and user migration.

[0039] (g) NDU contains data with different characteristics, which can be stored in different ways (such as database, file, block, etc.), provide different access methods, and use its own mechanisms such as distributed database and distributed file to achieve data security and high reliability.

[0040] It is worth noting that the NDU, as an independent data plane, not only provides core data and user data, but also adds network data and computing power data in this application, such as Figure 1b As shown, several types of data are introduced below.

[0041] User data: refers to end-to-end user data information, such as user access side capability data, low / medium / high speed tag data, user real-time trajectory, currently used network capabilities, currently ongoing tasks, currently ongoing services, etc.

[0042] Core data: refers to the core static data of users in the network, such as user contract data, business policy data, business contract data, etc.

[0043] Network data: It may include but is not limited to management data, operation data, SLA data, etc. of each network node, such as slice or subnet management data, load conditions of each network node, network service SLA data, network element data, etc.

[0044] Computing power data: refers to the computing power resources consumed by users and the service data built on them, such as computing power resource data, computing power service data, etc.

[0045] For the aforementioned data, NDU can provide data processing capabilities including but not limited to collection, preprocessing, storage, aggregation, analysis, orchestration, forwarding, AI services, etc., as well as data management capabilities including but not limited to distributed storage, load balancing, access control, security management, reliability management, etc. At the same time, it can also define a unified data format and provide data services to the outside world through the data service dual bus, solving the problem that the current independent data plane cannot be decoupled from different manufacturers.

[0046] It can be understood that, compared with the related art that requires multiple signaling and data interactions, the communication network architecture provided by the present application stores data in a unified manner, integrates the original multiple data interactions, and obtains and updates the required data once after signaling simplification and data merging. Among them, signaling simplification can be completed by NCU, and data merging can be completed by NDU.

[0047] Based on the above description, please refer to the above communication network architecture provided by this application again. Figure 1a, the interaction between the internal network elements (such as NCU, NDU, NIU, NPU, etc.) can rely on the dual bus (i.e., target bus) architecture. One is to reuse the service-based bus (Service Based Interface, SBI) in the relevant communication network architecture (such as 5G network architecture, 4G network architecture, etc.), that is, to continue the service-oriented design concept, and expand the scope of service from the core network control surface to the user surface, and further extend it to the wireless access side, so as to realize end-to-end service in the mobile network field. The other is the newly added data bus in this application, that is, the data channel or data channel bus or data channel interface (Data Channel Interface, DCI), so that different network units (such as NCU, NDU, NIU, etc.) can interact with each other through the data channel to achieve efficient acquisition and processing of data. For example, in this embodiment, the data channel is used to provide high-speed transmission of data (such as core data, network data, computing power data, etc.).

[0048] The SBI and DCI are introduced below respectively.

[0049] The SBI may have, but is not limited to, the characteristics shown in (a)-(c) below.

[0050] (a) The service bus can provide control message interaction between network elements. For example, based on the SBA architecture, network elements exchange signaling and data through the unified standard SBI; SBI is based on the HTTP / 2 protocol and has certain limitations in terms of data transmission size, type and efficiency.

[0051] (b) Inherit and integrate the existing SBI and evolve on the existing basis; the transport layer uniformly adopts the HTTP / 3 protocol, standardizes different service messages, and maintains the convenience and timeliness of data interaction

[0052] (c) As a low-throughput, high-performance signaling bus, SBI is suitable for data services with low data interaction volume that can be completed through signaling interaction.

[0053] And, for the DCI, it may have but is not limited to the characteristics shown in the following (a)-(d).

[0054] (a) As a high-throughput, high-reliability data bus, DCI is designed for the transmission and processing of non-real-time batch data or data that exceeds the SBI capability or large-volume data between network elements. It is suitable for data services with large data volumes, diverse types, and frequent interactions, making data transmission between network elements more efficient, secure, and reliable. It is especially suitable for large-volume data transmission scenarios such as endogenous AI, such as data used for AI training, machine learning models, etc.

[0055] (b) DCI is an advanced data transmission technology that provides a faster, more secure and reliable method to transmit different types of data. This method is network-based and can use any type of communication protocol.

[0056] (c) DCI supports a wider range of protocols and flexible configuration of communication protocols. It can support multiple methods including but not limited to FTP access to directories and files, block migration, etc.; for different data storage methods (such as databases, files, memory, etc.), it can provide different data access methods, such as Transmission Control Protocol (TCP), Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), RDMA, etc.

[0057] (d) Security considerations of DCI: When transmitting data through DCI, the communicating parties can determine the communication encryption method based on the data, protocol and other information to achieve secure data transmission. This includes but is not limited to identity authentication (such as tokens, which can be authorized and authenticated through SBI), standardized access interfaces and methods, and prevent information from being illegally accessed by unauthorized users; DCI uses encryption technology to protect data security and prevent information from being eavesdropped or leaked; DCI uses reliable technology to ensure data integrity and prevent it from being destroyed or tampered with during transmission. It supports data transmission of multiple data types and supports flexible configuration of communication encryption methods.

[0058] In the aforementioned communication network architecture provided in this application, on the one hand, unified data storage and management are achieved through an independent data plane, and consistent and standardized data services are provided, which can systematically solve the challenges of communication network control and value realization of non-user plane data. It can be understood that the independent data plane is designed to support end-to-end data collection, transmission, storage, analysis and sharing, and solve how to provide data conveniently, efficiently and securely to various network units of the future core network. Under the premise of complying with privacy protection and data security, reliable data services are provided to achieve cross-domain and cross-manufacturer data sharing, improve data service efficiency and data consistency; through the construction of unified platform capabilities, different data service forms are provided to meet flexible and diverse service needs.

[0059] On the other hand, each network element communicates with each other through the dual bus architecture of SBI and DCI. Among them, SBI provides signaling and data interaction between network elements, and DCI provides efficient transmission and processing of batch data. SBI and DCI do not affect each other, complement each other, and can be processed asynchronously and executed concurrently. Of course, when realizing data transmission between network elements, you can choose to transmit data through SBI or DCI according to actual needs, so as to ultimately achieve efficient collaboration between SBI and DCI in data services.

[0060] It should be noted that the HPMLN in FIG1 is a home public land mobile network and the VPMLN is a visited public land mobile network.

[0061] Based on the communication network architecture provided above, Figure 2 A flow chart of a communication method 200 provided in an embodiment of the present application is shown. The method 200 may be executed by a first network element, for example, by software or hardware installed in the first network element. Figure 2 As shown, the method 200 may include the following steps.

[0062] S210, the first network element communicates with the second network element based on the target bus.

[0063] The target bus includes an SBI and / or a DCI, and the SBI is used to provide signaling between network elements and interaction of the first data. Optionally, the first data may be data with a low data interaction volume that can be completed through signaling interaction. For example, the first data may be data with a data volume lower than a first threshold, data with an interaction frequency lower than a second threshold, etc. The first threshold and the second threshold may be set according to actual needs and are not limited here.

[0064] The DCI is used to provide interaction of second data between network elements. The second data includes at least one of the following (11)-(13).

[0065] (11) Data whose data volume exceeds the first threshold.

[0066] (12) Data that exceeds the service capability of the SBI. The SBI service capability may include the data type supported by the SBI for transmission, the data security requirements for the data supported by the SBI for transmission, etc.

[0067] (13) Data whose interaction frequency is greater than the second threshold.

[0068] In other words, the communication data interaction between network elements will rely on the dual-bus interconnection architecture, and DCI will be expanded (added) on the basis of retaining the current 5G communication network architecture SBI, as a high-throughput, high-reliability data link, for transmitting data that requires frequent interaction, large data volume, and diverse data types, to achieve efficient, reliable, and secure transmission of core network data, making data transmission between network elements more efficient, secure, and reliable. It is especially suitable for large-volume data transmission scenarios such as endogenous AI, such as data used for AI training, machine learning models, and so on.

[0069] In the present application, the first network element may be any one of NCU, NPU, NDU, and NIU, and the second network element may be any one of the NCU, NPU, NDU, and NIU. That is to say, in the network architecture provided in the present application, the first network element and the second network element may be the same or different network elements, such as the first network element and the second network element may both be NCU, NPU, NDU, or NIU, and for another example, the first network element may be any one of NCU, NPU, NDU, and NIU, and the second network element may be any one of NCU, NPU, NDU, and NIU except the first network element, etc.

[0070] It is worth noting that there can be multiple communication scenarios between the first network element and the second network element based on the dual bus. For example, the network elements need to frequently interact, batch acquire or store related data, such as the first network element needs to obtain related data from the NDU, such as core data, user data, network data, computing power data, etc., and the amount of data may be large and the data type may be different, so DCI can be used to achieve reliable, efficient and secure data transmission.

[0071] For another example, NIU (such as the first network element) needs to obtain a large amount of analysis, training, historical and other data for AI analysis, model training, etc. Among them, this scenario usually involves the transmission of big data. For example, the data that AI needs to process has different formats and data volumes, and the use of DCI transmission is more efficient.

[0072] For example, cross-domain data access (such as computing-network integration, end-to-end Quality of Service (QoS) assurance), federated learning model training, NWDAF data collection, and other scenarios that require collaboration between network units can all use the DCI bus to improve the transmission efficiency of model, gradient and other data, making data services safer and more efficient.

[0073] In this embodiment, the first network element and the second network element communicate with each other by adopting a dual bus (i.e., SBI and DCI). Therefore, on the one hand, it can support efficient and reliable transmission of data with large volume and high frequency requirements; on the other hand, it can also meet the real-time and customization requirements in the communication network.

[0074] Based on this, in one implementation method, for the process in which the first network element communicates with the second network element based on the target bus to realize data communication services, the first network element (i.e., the data requester) can receive the data transmission notification sent by the second network element (i.e., the data provider) based on the SBI, and the data transmission notification carries or indicates a data transmission mode to indicate whether the second network element transmits the target data to the first network element based on SBI or DCI. Therefore, by indicating the data transmission mode, the first network element and the second network element can have a consistent understanding of the transmission mode of the target data to improve the transmission reliability of the target data.

[0075] Among them, the data transmission notification can be sent by the second network element based on the data subscription service or data service request of the first network element, or it can be sent by the second network element according to its own data transmission needs, etc., which is not limited here.

[0076] For example, assuming that the data transmission notification may be sent by the second network element based on the data subscription service of the first network element, then the first network element may send a data subscription request or a second data service request to the second network element based on the SBI before receiving the data transmission notification sent by the second network element based on the SBI, so as to request the subscription of the target data. The data subscription request is used to subscribe to the target data from the second network element, and the second data service request is used to request the target data from the second network element.

[0077] For another example, assuming that the data transmission notification is sent by the second network element based on its own data transmission requirements, the second network element may send the data transmission notification to the first network element when it determines that data service is needed with the first network element, or when the second network element determines that the target data subscribed or requested by the first network element has changed.

[0078] Based on this, in a possible implementation method, for the data transmission method, the second network element can determine (decide) the data transmission method based on the relevant information of the target data (i.e., decision information), and save the decision result for the next interaction to improve data interaction efficiency.

[0079] The relevant information of the target data may be carried in the data subscription request or the second data service request, or may be determined by the second network element itself according to the requested or subscribed target data, which is not limited here.

[0080] Optionally, the relevant information of the target data may include at least one of the following (21)-(24).

[0081] (21) The data volume of the target data. For example, when the data volume does not exceed a first threshold (i.e., the data volume is small), it is determined to transmit the target data to the first network element based on the SBI; otherwise (i.e., the data volume is large), the target data is transmitted to the first network element based on the DCI.

[0082] (22) The data type of the target data, for example, whether the data type of the target data belongs to the range of data types supported by the SBI; if so, the target data is transmitted to the first network element based on the SBI; otherwise, the target data is transmitted to the first network element based on the DCI.

[0083] Among them, the range of data types not supported by the SBI may include but is not limited to data types stored in the form of files, directories, blocks, etc. For example, when the data type of the target data is a data type stored in the form of files, directories, blocks, etc., the target data is transmitted to the first network element based on DCI.

[0084] (23) Data exchange frequency of the target data. For example, if the data exchange frequency is not greater than a second threshold, it is determined that the target data is transmitted to the first network element based on the SBI; otherwise, the target data is transmitted to the first network element based on the DCI.

[0085] (24) Data security requirements of the target data. For example, when the data security requirements meet the SBI capability, determine to transmit the target data to the first network element based on the SBI; or, when the data security requirements are high or have special security requirements, or exceed the SBI capability, transmit the target data to the first network element based on the DCI.

[0086] Of course, when deciding the transmission method of the target data based on the above (21)-(24), the decision can be made according to any one of the above (21)-(24), or based on multiple of the above (21)-(24).

[0087] For example, when making a decision based on multiple of the above (21)-(24), the importance of each decision information in (21)-(24) can be determined respectively, and then the decision is made based on each decision information in turn according to the importance. If the decision information includes the above (21)-(24), then the decision process can include but is not limited to Figure 3 shown.

[0088] In one implementation, if the second network element determines, based on relevant information of the target data, that the second network element transmits the target data to the first network element based on SBI, the data transmission notification may also carry the target data to achieve fast and efficient transmission of the target data.

[0089] Alternatively, if the second network element determines based on the relevant information of the target data that the second network element transmits the target data to the first network element based on the DCI, the data transmission notification may also carry or indicate the following protocol related information for the target data transmission: 、 At least one of the data encryption related information. The protocol related information may include the transmission protocol, IP address, transmission port, etc. used when the target data is transmitted. The data encryption related information may include the encryption algorithm, key, token, etc. used when the target data is transmitted. Thus, it is ensured that the first network element can achieve the correct reception of the target data.

[0090] For example, after receiving the data transmission notification, the first network element may send a first data service request to the second network element based on the protocol-related information and data encryption-related information carried in the data transmission notification to request the target data. Then, after receiving the first data service request, the second network element may send a data service response to the first network element based on the DCI. Then, after the first network element receives the data service response sent by the second network element based on the DCI, it may also read the target data from the data service response carrying the target data based on the protocol-related information and / or data encryption-related information, thereby achieving safe and efficient transmission of the target data.

[0091] It is worth noting that, depending on the communication scenario, the aforementioned target data may be multiple. For example, it may be control plane data requested from NCU, user plane data requested from NPU, intelligent plane data requested from NIU, or data plane data requested from NDU, etc. It is understandable that in this application, in addition to the aforementioned NDU being able to provide data management related functions, the NCU, NPU, and NIU may also cache certain corresponding data to provide data communication services as a data provider.

[0092] Further, based on the above description, the following Figure 4a-4d , based on the Figure 1a The communication method implemented by the communication network architecture shown is further exemplarily introduced as follows. The first network element is a service requester, the second network element is a service provider, the first network element can be any one of the NCU, NPU, NIU, and NDU, and the second network element can also be any one of the NCU, NPU, NIU, and NDU.

[0093] Example 1

[0094] S401, a first network element initiates a data subscription request to a second network element through an SBI.

[0095] S402, after receiving the data subscription request, the second network element may determine (decide) how to transmit the target data according to the relevant information of the target data requested by the data subscription request. The relevant information of the target data (i.e., the basis for decision) includes the data volume, data type, interaction frequency, security requirements and other information of the subscribed target data, and the decision content includes the data transmission method (i.e., through SBI or DCI).

[0096] S403, the second network element sends a data subscription response (i.e., a data transmission notification) to the first network element. If the second network element decides to use DCI to transmit the target data, the data subscription response carries the data transmission method (such as whether to transmit the target data via SBI or DCI), protocol-related information, data encryption-related information (such as a token), etc.

[0097] In this example 1, by adding a local decision-making process in the data subscription process to decide whether to transmit the target data through SBI or DCI, the data transmission efficiency and transmission reliability can be effectively improved.

[0098] Example 2

[0099] Based on Example 1, if the second network element determines that the target data subscribed by the first network element changes, the implementation process may include:

[0100] S411, the second network element locally decides to use the SBI bus for data transmission notification, and the decision basis includes information such as data volume, data type, interaction frequency, security requirements, etc. The decision content includes the data transmission method (through SBI).

[0101] S412, the second network element sends a data transmission notification to the first network element through the SBI bus, which includes the data transmission mode (ie, SBI), subscribed target data, etc.

[0102] In this example 2, the data notification process adds a local decision process based on the existing SBI to decide whether to perform data notification through SBI or DCI. For the SBI method, data transmission notification can be performed directly through SBI.

[0103] Example 3

[0104] Based on Example 1, if the second network element determines that the target data subscribed by the first network element changes, the implementation process may include:

[0105] S421, the second network element locally decides to use the DCI bus for data notification. The decision is based on information such as data volume, data type, interaction frequency, and security requirements. The decision content includes the data transmission method (i.e., DCI), and also includes protocol-related information, data encryption-related information (such as tokens), etc. as needed.

[0106] S422, the second network element sends a data transmission notification to the first network element via the SBI bus, which includes a data transmission method (via DCI), protocol-related information, data encryption-related information, etc.

[0107] S423, the first network element sends a data service request to the second network element according to the received data transmission notification, based on the protocol related information and data encryption related information carried in the data transmission notification, and through the data transmission method (ie, DCI) indicated in the data transmission notification.

[0108] S424, the second network element sends a data service response to the first network element via the DCI bus, wherein the response includes target data of the data service request.

[0109] In this example 3, a local decision process is added to the data notification process to decide whether to perform data notification through SBI or DCI. For the DCI method, the second network element first notifies the data transmission method, protocol-related information, data encryption-related information, etc. through SBI, and the first network element then initiates a data service request through DCI. Among them, since DCI can support a wide range of data transmission protocols and provide support for data transmission beyond the capabilities of SBI, data transmission based on DCI is conducive to the efficient and secure transmission of large quantities of data and data in diversified formats.
