AI Technical Summary
The existing 5G network architecture suffers from high costs and high latency when meeting the data transmission needs of industry customers. In particular, data transmission latency is high when the terminal returns to the idle state, and user plane data needs to go through two hops, which increases processing overhead and latency.
By integrating the user plane functions of the core network into the second base station and integrating the core network control plane functions that affect service latency into the first base station, the network architecture is optimized in a low-cost manner, reducing inter-node interactions and achieving low-latency transmission.
By rationally allocating user plane and control plane functions to base stations, packet processing latency and overhead are reduced, network costs are lowered, and the requirements for low latency and secure isolation are met.

Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, specifically to a network architecture, a first base station, and a second base station. Background Technology
[0002] In local domain scenarios, many industry customers have a requirement for secure isolation of data that does not leave the domain. Therefore, when operators use 5G and other cellular networks to provide services to industry customers, they need to deploy user plane capabilities entirely locally, and data can be directly transmitted from the local server to the business server.
[0003] In 5G networks, to meet the data-in-place requirements of industry customers, the User Plane Function (UPF) network elements of the core network will be deployed locally, with an architecture as follows: Figure 1 As shown.
[0004] While the existing architecture can meet the security isolation requirements of industry customers, it has the following problems:
[0005] 1. If only the user plane of the core network is deployed, and the terminal returns to the idle state, sending data to the terminal requires paging initiated by the regional Access and Mobility Management Function (AMF), resulting in large downlink service latency; if both the core network control plane and user plane are deployed, the cost is high.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] The term "comprising," and any variations thereof, used in the specification and claims of this application, is intended to cover a non-exclusive inclusion.

Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.
[0055] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0056] See Figure 2 This application provides a network architecture including: one or more first base stations (e.g., 6G base station-C) and one or more second base stations (e.g., 6G base station-U), wherein one first base station establishes a connection with one or more second base stations, the first base station interacts with a terminal for control plane signaling, and the second base station interacts with the terminal for user data. The first base station includes: base station control plane functions and some core network user plane control functions, and the second base station includes: base station user plane functions and some core network user plane functions.
[0057] Understandably, the first base station is responsible for network management and control, handling signaling-related functions and tasks, such as at least one of the following: handling authentication and identity verification during user access; managing call control; implementing mobility management, handling mobile device switching and roaming in the network; providing security services to ensure the security of data transmission; and quality of service management.
[0058] The second base station handles actual user data transmission and traffic forwarding, including, for example, at least one of the following: packet switching; flow control; data compression and decompression; data encryption and decryption, etc.
[0059] This application does not limit the specific names of the first base station and the second base station. For example, the first base station may also be called a centralized control base station, a control plane base station, etc., and the second base station may also be called a distributed data base station, a user plane base station, etc.
[0060] In this embodiment, the second base station only includes the base station user plane function and the corresponding processing, and the first base station only includes the base station control plane function and the corresponding processing. Each first base station can control one or more second base stations, and each second base station can only be controlled by one first base station.
[0061] In one embodiment of this application, the first base station further includes at least one of the following: fusion plane control function and fusion plane execution function;
[0062] The fusion surface control function includes at least one of the following: perception control function, computing control function, data control function, artificial intelligence (AI) control function, computing node selection function, data acquisition configuration function, and perception node selection function.
[0063] The fusion surface execution function includes at least one of the following: perception execution function, data execution function, AI execution function, computation execution function, data storage function, data acquisition function, data processing function, high-performance computing function, AI model training function, AI model inference function, perception data association function, and perception data deduplication function.
[0064] It should be noted that the various functions in this application can be implemented by functional entities (hardware) or functional software, depending on the needs, performance and deployment requirements in a specific situation.
[0065] In one embodiment of this application, the second base station further includes a fusion plane execution function; the fusion plane execution function includes at least one of the following: data storage function, data acquisition function, data processing function, high-performance computing function, AI model training function, AI model inference function, perceptual data association function, and perceptual data deduplication function.
[0066] For example, 6G is a multi-element converged network. In addition to traditional communication-related user plane and control plane functions, it will also integrate non-communication capabilities such as sensing, computing, data, and artificial intelligence. Control functions related to sensing, computing, data, and AI will be integrated into the first base station, while related execution functions will be integrated into the second base station. Related control functions include computing node selection, data acquisition configuration, and sensing node selection. Related execution functions include data storage, data acquisition, data processing, high-performance computing, AI model training, AI model inference, sensing data association, and deduplication.
[0067] Example 1: Taking the paging process as an example, when downlink data is generated on the service server side, it is sent to the second base station. The second base station finds that the terminal is in a disconnected state, and triggers the first base station to initiate the paging process. The first base station broadcasts the paging message.
[0068] In one embodiment of this application, the first base station further includes core network control plane functions. Optionally, the core network control plane functions include at least one of the following: user registration function, authentication function, user management function, and capability opening function.
[0069] In one embodiment of this application, the first base station interacts with the terminal via control plane signaling through the second base station.
[0070] In this embodiment, the core network user plane functions are integrated into the second base station, and the core network control plane functions that affect service performance are integrated into the first base station.
[0071] From the perspective of local area network requirements, there are high demands for network performance, security isolation, and self-service commissioning and maintenance. Therefore, the core network functions are divided into user plane functions, user plane control functions, and control plane functions.
[0072] 1) Core network user plane functions: A set of functions that directly affect service performance (high frequency of interaction between nodes), such as data forwarding and data quality of service (QoS) mapping.
[0073] 2) Core network user plane control functions: A set of functions that indirectly affect service performance (with high frequency of interaction between nodes), such as session management, QoS control, slice selection, mobility management, paging, connection management, access control, routing, IP address lookup, etc.
[0074] 3) Core network control plane functions: A set of functions that have little impact on service performance (low frequency of interaction between nodes), such as user registration, authentication, user management, and capability opening. It does not include functions that are not needed in local scenarios, such as inter-system interoperability and international roaming.
[0075] Example 2: When a local scenario only requires network performance and security isolation (for one or both), the core network user plane functions can be integrated into the second base station, and the core network user plane control functions can be integrated into the first base station.
[0076] Example 3: When the local scenario also has the additional requirement of self-activation and self-service, the core network control plane functions need to be integrated into the first base station in the above-mentioned base station.
[0077] In one embodiment of this application, the core network user plane control function includes at least one of the following: session management function, QoS control function, slice selection function, mobility management function, paging function, connection management function, access control function, routing addressing function, and IP address lookup function.
[0078] In one embodiment of this application, the core network user plane function includes at least one of the following: data forwarding function and data QoS mapping function.
[0079] In one embodiment of this application, the core network control plane functions include at least one of the following: user registration function, authentication function, user management function, and capability opening function.
[0080] In the embodiments of this application, the changes in the connection relationship between functional modules are clearly defined, namely the changes in the protocol stack and the addition of new interactive content after the first base station and the second base station integrate the core network functions.
[0081] Option 1: After the core network functions are integrated into the base station, the base station will natively support the above functions. The interaction between the first base station (e.g., a control plane base station) and the second base station (e.g., a user plane base station) requires additional interactions between core network user plane control functions and between core network user plane functions and base station user plane functions. Interactions between nodes of the first base station will also include interactions between core network user plane control functions (e.g., when moving across first base stations, interactions between first base stations will require additional UE context (maintained by the original core network) interactions) and interactions between core network user plane control functions and base station control plane functions. Interactions between nodes of the second base station will also include interactions between core network user plane functions and interactions between the core network user plane and base station user plane. See [link to relevant documentation]. Figure 3 .
[0082] Taking the QoS guarantee process as an example, all end-to-end QoS mapping rules are uniformly controlled and issued by the core network. The existing 5G process is as follows: the Session Management Function (SMF) issues QoS profiles to the base station through the AMF to complete the uplink and downlink QoS mapping on the radio side; the SMF issues QoS rules to the UE through the AMF to complete the uplink data QoS mapping on the UE side; and the PCF issues Packet Detection Rules (PDR) to the UPF to complete the downlink data QoS mapping on the UPF side.
[0083] When the core network user plane control function is merged into the first base station and the core network user plane function is merged into the second base station, the first base station needs to add QoS profile and PDR distribution interaction to the second base station. Since the core network user plane function and the base station user plane function are merged into one second base station, the parameters of QoS profile and PDR can be merged and simplified. The second base station completes the QoS mapping process of uplink and downlink data based on the merged and simplified QoS mapping rules.
[0084] Meanwhile, the second base station protocol stack and the first base station protocol stack can be further simplified on the original basis, reducing the tunnel establishment and related protocol stack processing processes between the original base station and the core network, thereby reducing the processing latency of service data packets and reducing the processing overhead and resource overhead of the control plane.
[0085] In one embodiment of this application, the protocol stack of the second base station (e.g., a user plane base station) includes: Physical Layer (PHY), Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Service Data Discovery Protocol (SDAP), and IP (Internet Protocol). See [link to relevant documentation]. Figure 4 .
[0086] After simplifying the user plane protocol stack, taking uplink data sent by the terminal as an example, after passing through the terminal's IP layer and the air interface SDAP-PDCP-RLC-MAC-PHY layers, the base station receives the data and processes it through the reverse process of PHY-MAC-RLC-PDCP-SDAP. Without having to go through the two processing steps of wired GTP-U-UDP-IP-MAC-PHY, the data packet can be sent to the base station's IP layer for processing, and then sent to the external server through IP network communication.
[0087] In one embodiment of this application, the protocol stack of the first base station (e.g., a control plane base station) includes: PHY, MAC, RLC, PDCP, Radio Resource Control (RRC), and Non-Access Stratum (NAS). See [link to relevant documentation]. Figure 5 In another embodiment of this application, the protocol stack of the first base station includes RRC and NAS.
[0088] After the control plane protocol stack is simplified, taking the uplink signaling sent by the terminal as an example, after going through the terminal's air interface RRC-PDCP-RLC-MAC-PHY layer protocol processing, the base station receives it and after going through the reverse process of PHY-MAC-RLC-PDCP-RRC processing, it can be sent to the base station's NAS layer for processing without having to go through the two processing steps of wired NG-AP-SCTP-IP-MAC-PHY.
[0089] Option 2, based on Option 1, requires additional interactions between the second base station (e.g., a user plane base station) and the first base station (e.g., a control plane base station), including interactions between core network control plane functions and core network user plane functions, and interactions between core network control plane functions and base station user plane functions. It also requires additional interactions between the first base stations, including interactions between core network control plane functions and core network user plane control functions, and interactions between core network control plane functions and base station control plane functions. (See [link to relevant documentation]). Figure 6 .
[0090] The user plane and control plane protocol stacks of Scheme 1 and Scheme 2 can simplify the original wired communication protocol stack between the base station and the core network, with the RRC layer directly connected to the NAS layer and the SDAP layer directly connected to the IP layer.
[0091] Example 4: Taking the registration and authentication process as an example, under the existing architecture, the interaction between the first base stations is increased to include authentication and security information, subscription data and policy acquisition (UE access and mobility subscription data, SMF selection subscription data, UE context information in SMF, etc.), and terminal-related subscriptions.
[0092] In one embodiment of this application, the interaction between the first base station and the second base station includes at least one of the following:
[0093] 1) The interaction between the core network control plane function of the first base station and the base station user plane function of the second base station;
[0094] 2) The interaction between the core network control plane functions of the first base station and the core network user plane functions of the second base station;
[0095] 3) The interaction between the base station control plane function of the first base station and the core network user plane function of the second base station;
[0096] 4) The interaction between the core network user plane control function of the first base station and the base station user plane function of the second base station;
[0097] 5) Interaction between the core network user plane control function of the first base station and the core network user plane function of the second base station.
[0098] In one embodiment of this application, the interaction between the first base stations includes at least one of the following:
[0099] 1) Interaction between the base station control plane function of one first base station and the core network user plane control function of another first base station;
[0100] 2) Interaction between the base station control plane function of one first base station and the core network control plane function of another first base station;
[0101] 3) The interaction between the core network user plane control function of one first base station and the core network user plane control function of another first base station;
[0102] 4) Interaction between the core network user plane control function of one first base station and the core network control plane function of another first base station;
[0103] 5) Interaction between the core network control plane functions of one first base station and the core network control plane functions of another first base station.
[0104] In one embodiment of this application, the interaction between the second base stations includes at least one of the following:
[0105] 1) Interaction between the user plane function of one second base station and the core network user plane function of another second base station;
[0106] 2) Interaction between the core network user plane functions of one second base station and the core network user plane functions of another second base station.
[0107] In this embodiment, the architecture ensures that data packets reach their destination in a single hop, resulting in low end-to-end latency and minimal processing overhead. Simultaneously, the user plane functions with the most frequent interactions affecting service latency are integrated into the second base station, while the user plane control functions with numerous interactions are integrated into the first base station (in smaller numbers), thus meeting the low-latency requirements of services in a low-cost manner. In the network architecture of this application, local node-to-node interactions increase, while interactions between local and regional nodes decrease. This reduces the difficulty of interface decoupling should there be differences between local and regional vendors.

[0115] In this embodiment, user plane control functions with many interactions and numerous functions are integrated into the first base station (in small numbers) to meet the low latency requirements of services in a low-cost manner.
