[0031] The following will be combined with the 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 described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0032] 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 three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. The words "first", "second", etc. do not limit the quantity and execution order, and the words "first", "second", etc. do not limit them to be different.

[0033] It should be noted that in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] Core network (CN): It is one of the three major components of the communication network. The core network is the "management center" in the communication network, mainly responsible for managing data, sorting data, and then determining the destination of data, as well as core functions such as routing forwarding and signaling transmission.

[0035] Access network (RAN): is a part of a mobile communication system. It is the implementation of radio access technology. It exists between a device (for example, a mobile phone, a computer, or any remotely controlled machine) and the core network, providing a communication connection between the two.

[0036] Service-based architecture (SBA) is an important feature of 5G mobile communication systems. Combining the network characteristics and technology development trends of the mobile core network, network functions are divided into several reusable "services". "Services" communicate with each other using lightweight interfaces. Its goal is to achieve high efficiency, software-based, and open 5G systems. To adapt to the development of 5G networks, RAN has proposed a distributed architecture base station based on centralized units (CU) and distributed units (DU).

[0037] CU mainly includes non-real-time wireless high-level protocol stack functions, and also supports the sinking of some core network functions and the deployment of edge application services; while DU mainly handles physical layer functions and layer 2 functions with real-time processing requirements. In other words, the separation of CU and DU is based on the real-time nature of the processing content.

[0038] Secondly, under the CU-DU architecture, the CU further separates the control plane (CP) and the 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 and one CU-CP. Regarding the transmission content, the user plane is used to transmit user data (Data), and the control plane is used to transmit control plane signaling (signalling).

[0039] Among them, the control plane protocol stack includes radio resource control (RRC), packet data convergence protocol (PDCP), radio link control (RLC), medium access control (MAC), and physical layer (PHY). The user plane protocol stack includes service data adaptation protocol (SDAP), PDCP, RLC, MAC, and PHY. Existing communications require UE participation, and the network architecture and protocol stack are also for interconnection between UEs.

[0040] The 5G access network includes Node-B nodes, which support the centralized unit CU and DU separation deployment mode. For the separated Node-B scenario, RRC, PDCP and SDAP are set in the CU, and other protocol stacks are in the DU.

[0041] The NG interface is the interface between NG-RAN and the core network, which is used to transmit control information and user data between NG-RAN and the core network. The NG interface is divided into the control plane and the user plane. The energy nodes of the 5G core network include access and mobility management function (AMF), session management function (SMF), user plane function (UPF), network repository function (NRF), network exposure function (NEF), unified data management (UDM), etc. Among them, AMF, SMA, and UPF network elements are related to the access network.

[0042] Among them, AMF supports user terminals with different mobility management requirements. Main tasks: non-access layer (NAS) signaling terminals, NAS signaling security, access layer security control, core network node signaling for mobility between 3GPP access networks, idle mode user terminal reachability (including control and execution of paging retransmission), registration area management, support for intra-system and inter-system mobility, access authentication, access authorization (including roaming authority check), mobility management control (subscription and policy), support for network slicing, SMF selection.

[0043] SMF can work with AMF to support customized mobility management solutions, such as "mobile initiated connection only" (MICO) or RAN enhancements, such as the "RRC Inactive" state. Main tasks: session management, user terminal IP address allocation and management, UPF selection and control, configure flow control in UPF, route traffic to the appropriate destination, policy enforcement and quality of service (QoS) control part, downlink data notification.

[0044] UPF performs the following main tasks: 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 enforcement, traffic usage reporting, uplink classifier to support routing of service flows to the data network), branch point to support multi-host PDU sessions, QoS processing for the user plane (such as packet filtering, gating, uplink and downlink rate implementation), uplink service verification (SDF to QoS flow mapping), downlink packet buffering and downlink data notification triggering.

[0045] NRF provides support for network function (NF) service management, including registration, deregistration, authorization and discovery.

[0046] 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.

[0047] UDM supports a data storage architecture for separation of computing and storage for the 5G core network (5GC). The unified data repository (UDR) is the main database. An unstructured data storage function (UDSF) is introduced to store dynamic data.

[0048] For example, Figure 1 Provides existing 5G network architecture, such as Figure 1 As shown in the figure, the centralized unit control plane CU-CP in the RAN is connected to the 5G core network's capable node AMF through the N2 interface, and is connected to the DU through the F1-CP interface for transmitting user data; the centralized unit user plane CU-UP is connected to the 5G core network's capable node UPF through the N3 interface, and is connected to the DU through the F1-UP interface for transmitting control plane signaling; CU-CP and CU-UP are connected through the E1 interface, and data and signaling can be efficiently transmitted 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 through the N4 interface to implement functions such as user session management, user data transmission, and policy control.

[0049] A terminal device is a device with wireless transceiver function that can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (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 (Pad), a computer with wireless transceiver function, 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 application do not limit the application scenarios. A user terminal may sometimes also 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.

[0050] The base station can be long term evolution (LTE), long term evolution enhanced

[0051] The base station may include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, relays, transmit receive processors (TRP), wireless fidelity (WIFI) devices and other network side devices.

[0052] Existing 5G network services are all services related to terminal devices, such as voice, video, images, text, etc. With the evolution of standards and the development of technology, more and more research on 6G vision, requirements, and key technologies has been published. The 6G communication system will introduce intelligence, computing power, security, wireless network quality evaluation (such as service quality (QoS) and terminal user experience quality (QoE)), endogenous data management (data between wireless access network and core network interaction, data that does not require terminal participation in interaction, such as intelligence-related information, perception information), synaesthesia, energy supply, and computing power. One or more functions, among which computing power, external intelligence (such as: the network provides intelligence to the outside), one-way perception (such as: some perceptions only require network-level nodes to perceive, and do not require terminal devices to participate in perception), etc. do not require terminal devices to participate. 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 embodiment of the present application provides an access network and a communication system that can be used in 6G networks and future evolution networks.

[0053] 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 for data unrelated to terminal devices, and transmission of control information for 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.

[0054] In this way, compared with the existing access network, the user plane and the control plane can manage or transmit functions or data related to the terminal device while managing or transmitting functions or data unrelated to the terminal device, so that services unrelated to and related to the terminal device can coexist efficiently in the communication system, that is, network-level and terminal-level services can coexist efficiently. Such an access network can better adapt to future communication systems.
