[0030] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0031] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0032] It should be noted that in this disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present related concepts in some way.

[0033] The core network (CN) is one of the three major components of a communications network. As the network's "management hub," it is primarily responsible for managing and sorting data, determining its destination, and performing core functions such as routing, forwarding, and signaling.

[0034] The access network (RAN) is part of a mobile communications system. It implements radio access technology. It exists between a device (e.g., a mobile phone, a computer, or any remotely controlled machine) and the core network, providing the communication link between the two.

[0035] Service-based architecture (SBA) is a key feature of 5G mobile communication systems. Combining the network characteristics and technological development trends of the mobile core network, SBA divides network functions into reusable "services." These services communicate using lightweight interfaces. Its goal is to achieve high efficiency, software-based, and open 5G systems. To adapt to the development of 5G networks, the RAN has proposed a distributed base station architecture based on centralized units (CU) and distributed units (DU).

[0036] The CU primarily includes non-real-time wireless high-layer protocol stack functions, while also supporting the downlink of some core network functions and the deployment of edge applications. The DU, on the other hand, primarily handles physical layer and Layer 2 functions with real-time processing requirements. In other words, the separation between the CU and DU is based on the real-time nature of the processing content.

[0037] Secondly, under the CU-DU architecture, the CU further separates the control plane (CP) and user plane (UP), separating them into a centralized unit control plane (CU-CP) and a centralized unit user plane (CU-UP), and supports the connection of multiple CU-UPs to one CU-CP. In terms of transmission content, the user plane is used to transmit user data, and the control plane is used to transmit control plane signaling.

[0038] The control plane protocol stack includes radio resource control (RRC), packet data convergence protocol (PDCP), radio link control (RLC), medium access control (MAC), and the physical layer (PHY). The user plane protocol stack includes service data adaptation protocol (SDAP), PDCP, RLC, MAC, and PHY. Existing communications require the participation of the UE, and the network architecture and protocol stack are designed for interoperability between UEs.

[0039] The 5G access network includes Node-Bs, which support a separate deployment mode, centralized unit (CU) and separate unit (DU). In the separate Node-B scenario, RRC, PDCP, and SDAP are set up in the CU, and other protocol stacks are set up in the DU.

[0040] The NG (next generation) interface is the interface between the NG-RAN and the core network, used to transmit control information and user data between the NG-RAN and the core network. The NG interface is divided into the control plane and the user plane. The functional nodes of the 5G core network include the access and mobility management function (AMF), the session management function (SMF), the user plane function (UPF), the network repository function (NRF), the network exposure function (NEF), and the unified data management (UDM). Among them, the AMF, SMF, and UPF network elements are related to the access network.

[0041] The AMF supports user terminals with different mobility management requirements. Its main tasks are: non-access stratum (NAS) signaling termination, NAS signaling security, access stratum security control, core network inter-node signaling for mobility between 3GPP access networks, idle mode user terminal reachability (including control and execution of paging retransmissions), registration area management, support for intra-system and inter-system mobility, access authentication, access authorization (including roaming rights check), mobility management control (subscription and policy), support for network slicing, and SMF selection.

[0042] Together with the AMF, the SMF can support customized mobility management schemes such as "mobile initiated connection only" (MICO) or RAN enhancements such as the "RRC Inactive" state. The main tasks are: session management, user terminal IP (Internet Protocol) address allocation and management, UPF selection and control, configuring flow control in the UPF, routing traffic to the appropriate destination, policy enforcement and quality of service (QoS) control, and downlink data notification.

[0043] The main tasks performed by the UPF are: anchor point for intra-system and inter-system mobility, external packet data unit session (PDU) session point connected to the data network, packet routing and forwarding, packet inspection and user plane policy rule execution part, traffic usage reporting, uplink classifier (used to support routing of service flows to the data network), branch point supporting multi-home PDU sessions, QoS processing for the user plane (such as packet filtering, gating, uplink and downlink rate implementation), uplink service verification (SDF (service data flow) to QoS flow mapping), downlink packet buffering and downlink data notification triggering.

[0044] NRF provides support for network function (NF) service management, including registration, deregistration, authorization, and discovery.

[0045] NEF is used to provide external exposure of network functional capabilities. External exposure can be divided into monitoring capabilities, provisioning capabilities, application impact of traffic routing, and policy / billing capabilities.

[0046] The UDM supports a data storage architecture for the 5G core (5GC) that separates computing and storage. The unified data repository (UDR) serves as the primary database. An unstructured data storage function (UDSF) is introduced to store dynamic data.

[0047] For example, Figure 1 provides a 5G network architecture. As shown in Figure 1, the centralized unit control plane (CU-CP) in the RAN is connected to the 5G core network's capable node AMF via the N2 interface, and is connected to the DU via the F1-CP interface for transmitting control plane signaling; the centralized unit user plane (CU-UP) is connected to the 5G core network's capable node UPF via the N3 interface, and is connected to the DU via the F1-UP interface for transmitting user data; the CU-CP and CU-UP are connected via the E1 interface, allowing efficient data and signaling transmission between the user plane and the control plane. The core network's capable node SMF and the core network's capable node UPF are connected via the N4 interface to implement functions such as user session management, user data transmission, and policy control.

[0048] A terminal device is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons, and satellites, etc.). A user terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. A user terminal may also sometimes be referred to as a terminal, an access terminal, a UE (User Equipment) unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE device, etc.

[0049] A base station may be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system. The base station may include various network-side devices such as macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, relays, transmit receive processors (TRPs), and wireless fidelity (WIFI) devices.

[0050] 6G is a conceptual wireless network mobile communications technology. The design of the 6G system is currently in the candidate technology solicitation phase, and no detailed design plan has been released. 6G will support new services such as perception, intelligence, and computing power. As a completely new system, how to design and implement multiplexing of multiple new services, as well as multiplexing between new and existing services, requires research and solutions.

[0051] Existing 5G network services are all terminal-related services, such as voice, video, images, and text. With the evolution of standards and the development of technology, more and more research on the vision, requirements, and key technologies of 6G has been published. 6G communication systems will introduce one or more functions including intelligence, computing power, security, wireless network quality evaluation (such as quality of service (QoS) and terminal user quality of experience (QoE)), endogenous data management (data exchanged between the wireless access network and the core network, which does not require terminal participation in interaction, such as intelligence-related information and perception information), synaesthesia, energy supply, and computing power. Among them, computing power, external intelligence (such as the network providing intelligence to the outside world), and one-way perception (such as some perceptions only require network-level nodes to perceive, without the need for terminal devices to participate in perception) do not require terminal device participation. Therefore, when the network evolves to 6G, how to design the 6G network to ensure that services related to terminal devices and services not related to terminal devices can coexist efficiently needs to be solved urgently. In view of this, the embodiments of the present disclosure provide an access network and communication system that can be used in 6G networks and future evolved networks.

[0052] In view of this, the present disclosure proposes an access network, which includes at least a control plane and a user plane. The control plane is used for at least one of the following: management of network-level functions, management of network-level data, management of network-level tasks, transmission of control information related to network-level tasks, transmission of control information related to network-level data, transmission of network-level data, transmission of control information and / or data related to terminal devices, transmission of data unrelated to terminal devices, transmission of control information of data unrelated to terminal devices, and transmission of control information of tasks unrelated to terminal devices; the user plane is used for at least one of the following: transmission of data related to terminal devices, transmission of data unrelated to terminal devices, and transmission of network-level data.

[0053] Compared to existing access networks, the user plane and control plane can manage or transmit both terminal-related functions and data, as well as terminal-unrelated functions and data. This allows for efficient coexistence of terminal-unrelated and terminal-related services within the communication system, effectively ensuring the efficient coexistence of network-level and terminal-level services. This access network is better suited to future communication systems.

[0054] The access network provided by the embodiments of the present disclosure is introduced below with reference to the accompanying drawings.

These functions, which are unrelated to terminal devices, can be intelligent functions that do not require terminal device participation, such as computing power, external intelligence (e.g., the network provides intelligence to external parties), and one-way perception (e.g., some perception only requires network-level nodes, not terminal devices).
