Description

A single distributed unit (DU) can hardly support a large user scale or a wide coverage area. The collaboration of multiple transmit / receive points (TRP) across DUs can currently only be performed by the DU reporting to the central unit (CU) through the F1 interface (the main method is to transmit user-plane data from different DUs through different paths). However, the collaboration between DUs through the F1 interface and the CU is difficult to meet real-time requirements; and the terminal will also cause increased latency or data interruption when switching between DUs.

Therefore, key technologies such as Coordinated Multiple Points (CoMP) and Multiple Transmitting and Receiving Nodes (Multi-TRP, M-TRP) have been proposed. For details, please refer to Figure 2 (5G Network Architecture):

[0180] The 5G system uses a centralized and distributed approach for multi-point coordinated transmission and reception, and delegates multi-point coordination to the transmit / receive point (TRP) level, supporting highly dynamic coordination and effectively improving the throughput of cell-edge users. However, it should be noted that, due to the limitations of underlying software and hardware, a single distributed unit (DU) struggles to support large user bases or wide coverage areas. In many scenarios (such as ultra-dense networking), cross-DU multi-TRP coordination is required. Currently, however, cross-DU multi-TRP coordination can only be implemented through the central unit (CU). Information coordination between DUs requires reporting to the CU via the F1 interface, which then sends it to the cooperating DUs via the F1 interface (primarily by transmitting user plane data from different DUs via different paths). However, the path latency between the CU and the F1 interface makes it difficult to support coordinated transmission of DU data streams. Furthermore, handover between DUs can increase latency or cause data interruption. In Figure 2, 5GC represents the 5G core network (5GCore), NG represents the NG interface between 5GC and gNB, Xn-C represents the Xn-C interface between gNB and gNB-CU, gNB represents the 5G base station (the next generation Node B), and NG-RAN represents the next generation radio access network (Next Generation Radio Access Network).

[0181] To address the issues of low cell edge user data rates and cell handover data delays or interruptions that reduce coordinated multi-point transmission and reception performance in traditional cellular access network architectures, a user-centric access network architecture (as shown in Figure 3) has emerged with the development of mobile communication networks. By introducing flexible cells, multiple TRPs (belonging to different DDUs) across distributed data units (DDUs) are organized to coordinate transmission and serve a single user equipment (UE), thereby improving the user experience. Figure 3 is an example of a typical user-centric access network (6G user-centric network architecture). Specifically:

[0182] As shown in Figure 3, a flexible cell serving a UE is composed of multiple TRPs. The functions of each network element are described as follows:

[0183] (1) Cloud-based Control Unit (CCU), as the control plane anchor node, is responsible for control and management functions.

[0184] (2) DDU: User plane anchor point, responsible for data scheduling and transmission.

[0185] (3) TRP: TRP is a data transceiver node that undertakes radio frequency and some physical layer functions.

[0186] (4) Flexible cell: An area consisting of one or more access points (APs) or Transmitter Relays (TRPs) with some or all of the same access and transmission parameters. The control plane unit (CCU) flexibly enables and configures TRP candidate sets for terminals, meaning the coverage area is variable. The APs or TRPs in a flexible cell are flexibly organized by the data plane unit (DU). For any terminal, the DDU responsible for making scheduling decisions is called the primary DDU, while the DDU that only provides TRP resources and does not make scheduling decisions is called the secondary DDU.

[0187] In summary, for the 6G user-centric network adopting the CCU-DDU-TRP architecture, it is possible to consider introducing the G1 interface between DDUs for data forwarding and real-time scheduling to support the implementation of TRP groups (TRPGs) and TRP resource scheduling between Inter-DDUs, and realize the coordination of information of different protocol layers and different dimensions across DDUs (such as physical resource block (PRB) scheduling, interference information, data information, etc.) and collaborative scheduling based on this information, thereby converting more interference signals into useful resources and improving resource utilization efficiency.

[0188] Based on the foregoing, embodiments of the present disclosure provide an information processing method, apparatus, and device to address the problem in related art where information processing solutions for cross-access network data nodes cannot meet real-time requirements. The method, apparatus, and device are based on the same patent application concept. Since the principles for solving the problems are similar, the implementation of the method, apparatus, and device can refer to each other, and any repetitions will not be repeated.

[0189] The information processing method provided in the embodiment of the present disclosure is applied to a first access network data node, as shown in FIG4 , and includes:

[0190] Step 41: Receive first information sent by a control node; the first information includes: interface configuration information, or interface configuration information and a creation instruction;

[0191] Step 42: Create a user plane logical interface with the second access network data node based on the first information;

[0192] Step 43: Utilize the user plane logical interface to perform information coordination and / or data transmission with the second access network data node.

[0193] The interface configuration information may include relevant information for creating a user plane logical interface, such as user plane transport layer information (including: transport layer address and General Packet Radio Service Tunneling Protocol Tunnel Endpoint Identifier (GPRS Tunneling Protocol Tunnel Endpoint Identifier, GTP-TEID)); the creation indication may be used to indicate that a user plane logical interface is directly created with the second access network data node after receiving the first information, but is not limited to this.

[0194] The receiving of the first information sent by the control node may include: receiving an F1 interface message sent by the control node, or a newly added message; the first information is carried in the F1 interface message, or carried in the newly added message, but is not limited thereto. The creating of a user plane logical interface with the second access network data node based on the first information may include: interacting with the second access network data node based on the first information to create a user plane logical interface with the second access network data node; creating a user plane logical interface may include: creating relevant functional modules (such as receiving, sending, and message parsing and processing) at both ends of the first access network data node and the second access network data node, as well as a channel between the two ends, but is not limited thereto.

[0195] The information processing method provided by the embodiment of the present disclosure receives first information sent by a control node; the first information includes: interface configuration information, or interface configuration information and a creation indication; based on the first information, a user plane logical interface is created between the second access network data node; using the user plane logical interface, information collaboration and / or data transmission are performed with the second access network data node; it can support direct communication between access network data nodes, thereby avoiding communication delays or data interruptions caused by transit, and meeting the real-time requirements of information processing solutions across access network data nodes.

[0196] The interface configuration information includes: a transport layer address and a general packet radio service tunneling protocol tunnel endpoint identifier GTP-TEID; creating a user plane logical interface with the second access network data node based on the first information includes: sending a first request message to the second access network data node based on the first information; the first request message carries the GTP-TEID; receiving a first response message sent by the second access network data node, the first response message carries the GTP-TEID; wherein the GTP-TEID corresponds to a first target identifier, the first target identifier is the terminal identifier of the terminal to which the data between the first access network data node and the second access network data node belongs, or the first target identifier is the cell identifier of the cell to which the data between the first access network data node and the second access network data node belongs.

[0197] This allows accurate establishment of a user plane logical interface with the second access network data node. Sending the first request message to the second access network data node may include: sending the first request message to the second access network data node based on the transport layer address. Furthermore, the first request message may carry, but is not limited to, relevant information about the interface configuration information, such as relevant information used for subsequent transmission. The GTP-TEID may be understood as a channel identifier, but is not limited to this. The transport layer address may be an IP address. The first request message may be an echo request (i.e., (Echo req)) message, the first response message may be an echo response (i.e., (Echo resp)) message, the terminal identifier may be the gNB-CU UE F1AP ID, and the cell identifier may be the gNB-DU ID+PCI, but is not limited to these.

[0198] In the embodiment of the present disclosure, sending a first request message to the second access network data node based on the first information includes: sending a first request message to the second access network data node based on the interface configuration information and the requirement information; the requirement information includes: at least one of information collaboration requirement information and data transmission requirement information; or, sending a first request message to the second access network data node based on the interface configuration information and the creation indication.

[0199] This can be applied to creating user plane logical interfaces in many situations, such as creating them directly according to instructions or creating them when needed.

[0200] Among them, the terminal identifier is an F1 interface application protocol identifier, or the terminal identifier is represented by a cell identifier and a cell radio network temporary identifier C-RNTI; and / or, the cell identifier is an access network data node identifier and a physical cell identifier (Physical Cell Identifier, PCI), or a new radio cell global identifier (NR Cell Global Identifier, NR CGI), or other unique physical layer resource identifiers between access network data nodes; the other unique physical layer resource identifiers refer to unique physical layer resource identifiers other than the access network data node identifier and PCI, and the NR CGI.

[0201] This can support unique, accurate, and multi-faceted representation of terminal identification and / or cell identification. The F1 interface application protocol identifier (F1AP ID) can be, but is not limited to, the gNB-CU UE F1AP ID.

[0202] In the embodiment of the present disclosure, the use of the user plane logical interface to transmit data with the second access network data node includes: using the user plane logical interface to perform target data transmission according to the GTP-TEID; wherein, when the target data includes multiple access channel protocol data unit data, or physical layer bit stream data of a terminal, the first target identifier is the terminal identifier; or, when the target data includes physical layer bit stream data of at least two terminals, the first target identifier is the cell identifier.

[0203] This allows for accurate data transmission. It is noted that a user plane logical interface has multiple GTP tunnels as data channels, and each data channel is distinguished by a TEID. In this disclosure, in order to achieve transparent data transmission between access network data nodes, when the data transmitted at the Media Access Control (MAC) layer is a UE data stream multiplexed by a Data Radio Bearer (DRB), a unique terminal identifier between access network data nodes under the control node is required to distinguish the data stream for subsequent processing. Similarly, when multiple UE streams at the physical layer (PHY) are mapped and multiplexed into a cell bitstream, a cell (resource) identifier is required to distinguish the data for subsequent processing.

[0204] Furthermore, the information processing method further includes: receiving updated interface configuration information sent by the control node; wherein the interface configuration information is carried in an F1 interface message, or carried in a newly added message.

[0205] This allows for receiving updated interface configuration information in multiple ways. Specifically, "carrying interface configuration information in an F1 interface message" may include adding interface configuration information to an existing F1 interface message, such as adding a user plane transport layer information list (UP Transport Layer Information list); and "carrying interface configuration information in a newly added message" may include adding an initial creation message and an update message of the control node to carry the interface configuration information, but this is not a limitation. Furthermore, the first access network data node may subsequently continue to create a user plane logical interface based on the updated interface configuration information, which is not limited here.

[0206] The control node is a central unit CU or a cloud control unit CCU.

[0207] This can support the application of this solution to various network architectures. In addition, the control nodes connected to the first access network data node and the second access network data node are the same or different, for example: the first access network data node is connected to the first central unit CU or the first cloud control unit CCU; the second access network data node is connected to the second CU or the second CCU; wherein the first CU and the second CU are the same CU or different CUs, and the first CCU and the second CCU are the same CCU or different CCUs; but this is not limited to this.

[0208] In an embodiment of the present disclosure, the interface configuration information is used to indicate the creation of a user plane logical interface between access network data nodes within a first range; wherein, the access network data nodes within the first range include any one of the following: all access network data nodes connected to the same control node; all access network data nodes involved in the collaborative transceiver point set TRPG; the main access network data node and the auxiliary access network data node in the collaborative TRPG.

[0209] This can support multiple situations in which a user plane logical interface can be created between multiple access network data nodes at one time.

[0210] The present disclosure also provides an information processing method, which is applied to a control node, as shown in FIG5 , and includes:

[0211] Step 51: Determine interface configuration information between the first access network data node and the second access network data node;

[0212] Step 52: Send first information to the first access network data node based on the interface configuration information, or send first information to the first access network data node and the second access network data node respectively; wherein the first information includes: the interface configuration information, or the interface configuration information and a creation indication.

[0213] In which, the interface configuration information may include relevant information for creating a user plane logical interface, such as user plane transport layer information (including: transport layer address and General Packet Radio Service Tunneling Protocol Tunnel Endpoint Identifier GTP-TEID); the creation indication can be used to indicate that a user plane logical interface is directly created between the second access network data node after receiving the first information, but is not limited to this.

[0214] The information processing method provided by the embodiment of the present disclosure determines the interface configuration information between the first access network data node and the second access network data node; sends first information to the first access network data node according to the interface configuration information, or sends first information to the first access network data node and the second access network data node respectively; wherein the first information includes: the interface configuration information, or the interface configuration information and a creation indication; can support the first access network data node to create a user plane logical interface with the second access network data node according to the first information, thereby utilizing the user plane logical interface to directly perform information collaboration and / or data transmission with the second access network data node; that is, can support direct communication between access network data nodes, thereby avoiding communication delays or data interruptions caused by transit, and meeting the real-time requirements of information processing solutions across access network data nodes.

[0215] In which, the interface configuration information includes: transport layer address and GTP-TEID; and / or, the first access network data node is any one of all access network data nodes connected to the control node, and the second access network data node is any one of all access network data nodes connected to the control node except the first access network data node; or, the first access network data node is any one of the access network data nodes connected to the control node for collaboration, and the second access network data node is any one of the access network data nodes connected to the control node for collaboration except the first access network data node; or, the first access network data node is the primary access network data node in the collaborative TRPG, and the second access network data node is the secondary access network data node in the collaborative TRPG.

[0216] This can support the first access network data node to accurately send a first request message to the second access network data node based on the first information to create a user plane logical interface; and / or support the first access network data node in multiple scenarios to create a user plane logical interface between the first access network data node and the second access network data node.

[0217] In an embodiment of the present disclosure, the GTP-TEID corresponds to a first target identifier; the first target identifier is the terminal identifier of the terminal to which the data between the first access network data node and the second access network data node belongs, or the first target identifier is the cell identifier of the cell to which the data between the first access network data node and the second access network data node belongs.

[0218] This can support the first access network data node to accurately establish a user plane logical interface with the second access network data node. The GTP-TEID can be understood as a channel identifier, but is not limited thereto.

[0219] Among them, the terminal identifier is the F1 interface application protocol identifier, or the terminal identifier is represented by the cell identifier and the cell radio network temporary identifier C-RNTI; and / or, the cell identifier is the access network data node identifier and the physical cell identifier PCI, or the new radio cell global identifier NR CGI, or other unique physical layer resource identifiers between access network data nodes; the other unique physical layer resource identifiers refer to unique physical layer resource identifiers other than the access network data node identifier and PCI, and the NR CGI.

[0220] This can support unique, accurate, and multi-faceted representation of terminal identification and / or cell identification. The F1 interface application protocol identifier (F1AP ID) can be, but is not limited to, the gNB-CU UE F1AP ID.

[0221] In an embodiment of the present disclosure, when multiple access channel protocol data unit data or physical layer bit stream data of a terminal is transmitted between access network data nodes, the first target identifier is the terminal identifier; or, when the physical layer bit stream of at least two terminals is transmitted between access network data nodes, the first target identifier is the cell identifier.

[0222] This can support accurate data transmission between the first access network data node and the second access network data node.

[0223] Furthermore, the information processing method also includes: updating the interface configuration information; sending the updated interface configuration information to the first access network data node; wherein the interface configuration information is carried in the F1 interface message, or carried in a new message.

[0224] In this way, the updated interface configuration information can be transmitted in multiple ways. Updating the interface configuration information may include, but is not limited to, updating the interface configuration information when the TRPG is updated. Furthermore, of course, the present disclosure may also include sending the updated interface configuration information to the second access network data node, which is not limited here.

[0225] The interface configuration information corresponds to at least one terminal.

[0226] This can support the reuse of the interface configuration information.

[0227] In an embodiment of the present disclosure, the interface configuration information is used to indicate the creation of a user plane logical interface between access network data nodes within a first range; wherein, the access network data nodes within the first range include any one of the following: all access network data nodes connected to the same control node; all access network data nodes involved in the collaborative transceiver point set TRPG; the main access network data node and the auxiliary access network data node in the collaborative TRPG.

[0228] This can support multiple situations in which a user plane logical interface can be created between multiple access network data nodes at one time.

[0229] It is to be noted that the above-mentioned contents related to the first access network data node and the control node can refer to each other, and the repeated parts will not be repeated.

[0230] The information processing method provided in the embodiments of the present disclosure is described below with examples.

[0231] In response to the above technical problems, the embodiments of the present disclosure provide an information processing method, which can be specifically implemented as an access network interface creation method, supporting the solution to the problem that the collaboration of multiple transmit / receive nodes (Transmit / Receive Point, TRP) across access network data nodes in the communication network through control node operation is difficult to meet the real-time requirements of scheduling and data transmission; wherein the control node can be a central unit (Central Unit, CU) and the access network data node can be a distributed unit (Distributed Unit, DU). This solution mainly involves: introducing a user plane logical interface G1 between access network data nodes (functions) to provide real-time information collaboration and data transmission functions, and the control node (function) controls and maintains the necessary information required to establish G1 and notifies the data node to operate and adopt different tunnel identifiers for transmission at different protocol layers.

[0232] Specifically, this plan includes the following contents:

[0233] 1. Establish a user plane logical interface G1 between access network data nodes (e.g., 5G DU, 6G DDU, or other network devices with the same function) for information collaboration and data transmission. The G1 interface (i.e., user plane logical interface G1) can use the protocol stack shown in Figure 6 for information transmission. In Figure 6, User plane PDUs represents user plane protocol data units, GTP-U represents the user plane General Packet Radio Service (GPRS) tunneling protocol (GPRS Tunnel Protocol) layer, UDP represents the user datagram protocol (User Datagram Protocol) layer, IP represents the network protocol layer, Data link layer represents the data link layer, and Physical layer represents the physical layer.

[0234] a) Based on the network architecture (5G or 6G), a G1 interface can be established between different access network data nodes connected to the control node. In this solution, the control node is only responsible for maintaining and notifying the necessary information when the G1 interface between access network data nodes is initially established. The G1 interface is for subsequent transmission between access network data nodes and is unrelated to the control node. In related technologies, any message transmission between access network data nodes must be transferred through the control node. The control node can be a 5G CU or 6G CCU, and the access network data node can be a DU or DDU, which are not limited here.

[0235] b) Furthermore, the G1 interface can also be extended to access network data nodes under different control nodes. The two interacting access network data nodes can be nodes under the same network architecture or nodes under different network architectures, which is not limited here.

[0236] 2. The establishment of the G1 interface and the necessary interface management and maintenance information are transmitted by the control node (such as 5G CU, or 6G CCU, or other network devices with the same function) to the corresponding access network data node through the F1 interface message.

[0237] 3. The interface configuration information is used to instruct the creation of a user plane logical interface between access network data nodes within a first range. Specifically, it may include: a G1 interface may be established in access network data nodes in different ranges after the user accesses, for example:

[0238] a) All access network data nodes connected to the same control node, such as between all DDUs connected under the CCU;

[0239] b) All access network data nodes involved in a cooperative transmission reception point group (TRPG), such as all DDUs involved in a cooperative TRPG configured according to the network;

[0240] c) A primary access network data node and a secondary access network data node in a collaborative TRPG, such as between a primary and secondary DDU in a collaborative TRPG according to network configuration;

[0241] The above b) / c) are applicable to cooperative DDUs determined in other forms in a non-user-centric network, but are not limited thereto.

[0242] 4. Based on 3, the control node determines the interface configuration information and transmits it to the access network data node through the F1 interface; wherein the interface configuration information may be that the control node establishes and maintains an access network data node list based on the access network data node for establishing the G1 interface and the necessary information, including the transport layer address (Transport Layer Address) and GTP tunnel endpoint identifier (GPRS Tunneling Protocol Tunnel Endpoint Identifier, GTP-TEID) corresponding to each access network data node; specifically, for example, the control node is a CCU, and the access network data node is a DDU. The CCU establishes and maintains a list DDU list based on the DDU for establishing the G1 interface and the necessary information (the DDU needs to be reported to the CCU first if TRPG is configured). The list includes the Transport Layer Address and GTP-TEID corresponding to each DDU and is transmitted to the DDU through the F1 interface; specifically:

[0243] a) Based on 3a) or 3b), the DDU list can be distributed to all or cooperating DDUs;

[0244] b) Based on 3c), only the DDU list needs to be informed to the master DDU;

[0245] 5. Based on 3b) or 3c), the control node updates the interface configuration information; sends the updated interface configuration information to the first access network data node; for example: the control node takes CCU as an example, when the TRPG is updated, the CCU synchronizes the DDU list to the DDU (which can be executed according to a) and b) in 4).

[0246] 6. The first access network data node uses the user plane logical interface to perform target data transmission according to the GTP-TEID; specifically, for example, the first access network data node takes DDU as an example, and the DDU uses different unique corresponding GTP-TEIDs for data transmission according to the position of the protocol stack corresponding to the interface or the content of the GTP data packet received by GTP-TEID, as shown in Figure 7 (in the figure, DDU-L represents a distributed data unit low-layer node, RLC represents a radio link control layer, MAC represents a media access control layer, PHY represents a physical layer, DRB represents a data radio bearer, TB represents a transport block, and Bitstream represents a bit stream).

[0247] a) GTP-TEID corresponds to the first target identifier. When the target data includes multiple access channel protocol data unit data, the first target identifier is the terminal identifier. For example, when the interface transmits multiple access channel protocol data unit (MAC PDU) and necessary information, GTP-TEID corresponds to the unique UE ID of the terminal to which the data between DDUs belongs. Specifically, as shown in FIG7 , the first DRB1 and the first DRB2 respectively represent the data radio bearer 1 and data radio bearer 2 corresponding to UE1 in RLC, the second DRB1 represents the data radio bearer 1 corresponding to UE2 in RLC, the third DRB1 represents the data radio bearer 1 corresponding to UE3 in RLC, UE1TB represents the transmission block after multiplexing all data radio bearers of UE1 in MAC, UE2TB represents the transmission block after multiplexing UE2 data radio bearers in MAC, UE3TB represents the transmission block after multiplexing UE3 data radio bearers in MAC, TB(UE ID1) represents the transmission channel between two DDU-L MACs with the GTP-TEID corresponding to UE ID 1 being TEID 1, and TB(UE ID2) indicates the transmission channel between two DDU-L MACs with the GTP-TEID corresponding to UE ID 2 being TEID 2;

[0248] b) GTP-TEID corresponds to the first target identifier. When the target data includes the physical layer bit stream data of a terminal, the first target identifier is the terminal identifier. For example, when the interface transmits a single UE physical layer bit stream (bitstream) and necessary information, GTP-TEID corresponds to the unique UE ID of the terminal to which the data between DDUs belongs. Specifically, Bitstream (UE ID1) in Figure 7 indicates that the bit stream between two DDU-L PHYs belonging to UE ID1 corresponds to the transmission channel with GTP-TEID TEID 1, and Bitstream (UE ID2) indicates that the bit stream between two DDU-L PHYs belonging to UE ID2 corresponds to the transmission channel with GTP-TEID TEID TEID2.

[0249] c) GTP-TEID corresponds to the first target identifier. When the target data includes physical layer bit stream data of at least two terminals, the first target identifier is the cell identifier; for example: when the interface transmits a multi-UE mixed physical layer bit stream and necessary information, GTP-TEID corresponds to the unique cell identifier (cell id) of the cell to which the data between DDUs belongs (for example, it can be a physical layer resource id); specifically: as shown in Figure 7, Cell ID1 represents the physical layer resource 1 carried by UE1TB, UE2TB and UE3TB after processing in PHY, and Bitstream (cell ID1) represents the transmission channel whose GTP-TEID corresponding to the bit stream carried by cell ID1 between two DDU-L PHYs is TEID 1.

[0250] Among them, TRP2 and TRP3 in Figure 7 can form a TRPG, thereby establishing an inter-DU interface to assist TRPGs (TRP2 and 3) to serve the UE together, but the present invention is not limited to this.

[0251] 7. Based on 6, GTP-TEID has the following correspondence:

[0252] a) Based on 6a) or 6b), the terminal identifier is the F1 interface application protocol identifier, or the terminal identifier is represented by the cell identifier and the cell radio network temporary identifier (C-RNTI). The F1 interface application protocol identifier may be the gNB-CU UE F1AP ID, which can be specifically understood as: the UE ID is represented by the gNB-CU UE F1AP ID or the cell ID + the cell radio network temporary identifier (C-RNTI);

[0253] b) Based on 6c), the cell identifier is the access network data node identifier and the physical cell identifier PCI, or the new radio interface cell global identifier NR CGI, or other unique physical layer resource identifiers between access network data nodes; the other unique physical layer resource identifier refers to a unique physical layer resource identifier other than the access network data node identifier and PCI, and the NR CGI; wherein the access network data node identifier can be a gNB-DU ID, which can be specifically understood as: using gNB-DU ID + physical cell identifier (Physical Cell Identifier, PCI) or NR CGI or other unique physical layer resource IDs between DDUs (i.e., other unique physical layer resource IDs between DDUs) to represent the cell ID.

[0254] 8. The interface configuration information corresponds to at least one terminal; for example, for multiple UEs, the network may maintain a separate DDU list for each UE or maintain a total DDU list.

[0255] The following is a specific example to illustrate this solution.

[0256] Example 1: Establishing a G1 interface under a 5G architecture, wherein the control node takes a 5G CU as an example, and the access network data node takes a 5G DU as an example;

[0257] As shown in FIG8 , this embodiment may include the following steps:

[0258] Step 1: After the control node (e.g., gNB-CU) and access network data node (e.g., gNB-DU) start up, the access network data node (e.g., gNB-DU) initiates the F1 interface establishment process. The control node (e.g., gNB-CU) obtains the access network data node identifier, transport layer address (IP address), and PCI of all connected access network data nodes (e.g., gNB-DU). The access network data node identifier can be the gNB-DU ID.

[0259] Step 2: After network initialization, the UE connects to the first access network data node (e.g., gNB-DU1) and establishes or updates a user context. The control node (e.g., gNB-CU) obtains the F1 interface application protocol identifier (e.g., gNB-CU UE F1AP ID) as the UE ID. This means that the UE context is established / updated and the UE ID is obtained. The F1 interface application protocol identifier (e.g., gNB-CU UE F1AP ID) is an F1 interface parameter that uniquely identifies a UE within a control node (e.g., gNB-CU) (including multiple connected DUs). This solution uses this identifier to establish a transmission channel between access network data nodes (e.g., gNB-DUs) and distinguish and recover data from different UEs at the MAC layer of the receiving access network data node (e.g., gNB-DU).

[0260] Step 3: The control node (e.g., gNB-CU) determines the interface configuration information (e.g., establishing a DU list) based on the information obtained in steps 1 and 2, including the UP Transport Layer Information (including Transport Layer Address and GTP-TEID) of each access network data node (e.g., gNB-DU). Specifically:

[0261] a) When the target data includes multiple access channel protocol data unit data or physical layer bit stream data of a terminal, the first target identifier is the terminal identifier. Specifically, when MAC layer data is transmitted between access network data nodes (e.g., gNB-DU) or physical layer data is transmitted between access network data nodes (e.g., gNB-DU) for a single UE, a GTP-TEID corresponding to the UE ID is generated.

[0262] b) When the target data includes physical layer bit stream data of at least two terminals, the first target identifier is the cell identifier. Specifically, for example, when multiple UEs transmit physical layer data between access network data nodes (e.g., gNB-DUs), a GTP-TEID corresponding to the access network data node identifier (e.g., gNB-DU ID) + PCI is generated.

[0263] The GTP-TEID is generated by the control node (e.g., gNB-CU). The control node (e.g., gNB-CU) can generate GTP-TEIDs for the above two situations. It can also predict in advance what type of data will be transmitted between access network data nodes (e.g., gNB-DU) to generate the corresponding GTP-TEID. This is not limited here.

[0264] Step 4: The control node (e.g., gNB-CU) sends the interface configuration information (e.g., DU list) to all connected access network data nodes (e.g., gNB-DU). Specifically, the interface configuration information may be transmitted via an F1 interface message, but is not limited thereto.

[0265] Step 5: The first access network data node (e.g., gNB-DU1) sends a first request message to the second access network data node (e.g., gNB-DU2) based on the interface configuration information and requirement information, and receives a first response message sent by the second access network data node (e.g., gNB-DU2). The first request message may be an echo request message, and the first response message may be an echo response message. Specifically, for example, when the first access network data node (e.g., gNB-DU1) requires collaboration and / or data forwarding from the second access network data node (e.g., gNB-DU2), it sends an echo request message (to request confirmation of the G1 interface), and gNB-DU2 replies with an echo response message to confirm the establishment of the G1 interface.

[0266] Step 6: The first access network data node (e.g., gNB-DU1) uses the Transport Layer Address and GTP-TEID of the second access network data node (e.g., gNB-DU2) obtained in Step 4 to send coordinated information or data to the receiving end of the second access network data node (e.g., gNB-DU2) corresponding to the Transport Layer Address via the GTP tunnel indicated or identified by the GTP-TEID. This enables data transmission, including coordinated transmission (e.g., TB or bitstream) between access network data nodes (e.g., gNB-DUs). Specifically, the access network data nodes may exchange information via the G1 interface.

[0267] The establishment of the G1 interface includes the establishment of the GTP transceiver function. After gNB-DU1 and gNB-DU2 establish the GTP transceiver function, the gNB-DU1 sender function only needs to know the IP address and TEID of the receiving end to send data to the other end. In this embodiment 1, the transceiver function has been established in step 5. In step 5, sending an echo request also requires knowing the IP address of the other end. The TEID can use the default value (for example, 0).

[0268] Example 2: Establishing a G1 interface under a 6G architecture, wherein the control node is 6G CCU as an example, and the access network data node is 6G DDU as an example;

[0269] As shown in FIG9 , this embodiment may include the following steps:

[0270] Step 1: After the control node (such as CCU) and the access network data node (such as DDU) are started, the access network data node (such as DDU) initiates the F1 interface establishment process, and the control node (such as CCU) obtains the Transport Layer Address (transport layer address, i.e. IP addr) and Cell ID of all connected access network data nodes (such as DDU).

[0271] Step 2: After network initialization is completed, the UE accesses the first access network data node (such as DDU1); the control node (such as CCU) configures a TRPG for the UE and determines the interface configuration information (such as establishing a DDU list) based on the collaborative auxiliary access network data node (such as auxiliary DDU) involved in the TRPG, including the UP Transport Layer Information (including Transport Layer Address and GTP-TEID) of the auxiliary access network data node (such as auxiliary DDU), where the generated GTP-TEID and Cell ID correspond one to one. Among them, the TRPG configured by the control node (such as CCU) may be: the first access network data node (such as DDU1) is the primary access network data node (such as primary DDU).

[0272] Step 3: The control node sends the first information to the first access network data node based on the interface configuration information; for example: the control node (such as CCU) sends the interface configuration information (such as DDU list) to the first access network data node (i.e., the main access network data node, such as DDU1-main DDU) through the F1 message.

[0273] Step 4: The first access network data node (i.e., the primary access network data node, such as DDU1-primary DDU) sends a first request message to the second access network data node (i.e., the secondary access network data node, such as DDU2-secondary DDU) according to the interface configuration information and requirement information; and receives a first response message sent by the second access network data node; wherein the first request message may be an echo request message, and the first response message may be an echo response message; specifically, for example: when the first access network data node (i.e., the primary access network data node, such as DDU1-primary DDU) requires the second access network data node (i.e., the secondary access network data node, such as DDU2-secondary DDU) to collaborate and / or forward data, it sends an echo request message to the second access network data node (i.e., the secondary access network data node, such as DDU2-secondary DDU), and the second access network data node (i.e., the secondary access network data node, such as DDU2-secondary DDU) replies with an echo response message to confirm that the G1 interface is established.

[0274] Step 5: The first access network data node (i.e., the primary access network data node, such as DDU1 - primary DDU) uses the UP Transport Layer Information from step 2 to send physical layer data and information to the second access network data node (i.e., the secondary access network data node, such as DDU2 - secondary DDU). This involves data transmission, including coordinated transmission (e.g., bitstream) between access network data nodes (e.g., DDUs). Specifically, information exchange between access network data nodes can be performed via the G1 interface.

[0275] Step 6: When the user moves, the control node (such as CCU) updates the TRPG for the UE and repeats the process of steps 2-5 to re-establish the G1 interface and transmission, that is: the UE moves, and the TRPG and interface configuration information (such as DDU list) are updated; then the control node (such as CCU) sends an F1 interface message to the first access network data node (that is, the primary access network data node, such as DDU1-primary DDU) to update the G1. The subsequent steps are consistent with steps 4-5 and will not be repeated here.

[0276] Example 3: Establishing a G1 interface under a 6G architecture, wherein the control node is 6G CCU as an example, and the access network data node is 6G DDU as an example;

[0277] As shown in FIG10 , the solution of this embodiment may specifically include the following steps:

[0278] Step 1: After the control node (such as CCU) and the access network data node (such as DDU) are started, the access network data node (such as DDU) initiates the F1 interface establishment process, and the control node (such as CCU) obtains the Transport Layer Address (IP addr) of all connected access network data nodes (such as DDU).

[0279] Step 2: After network initialization is completed, the UE accesses the first access network data node (such as DDU1) and establishes or updates the user context. The control node (such as CCU) obtains the UE's unique UE ID under the current control node (such as CCU) connection.

[0280] Step 3: The control node (such as CCU) configures TRPG for the UE (i.e., determines TRPG), and determines the interface configuration information (such as establishing a DDU list) based on the information obtained in steps 1 and 2, including the UP Transport Layer Information (including Transport Layer Address and GTP-TEID) of all collaborative access network data nodes (such as DDU) involved in TRPG, where the generated GTP-TEID and UE ID correspond one to one.

[0281] Step 4: The control node sends the first information to the first access network data node based on the interface configuration information; for example: the control node (such as CCU) sends the interface configuration information (such as DDU list) to the collaborative access network data node (including the first access network data node) through the F1 message, that is, the transmission G1 establishes the configuration; wherein, the collaborative access network data node can be a collaborative DDU, specifically, the collaborative access network data node can include the first access network data node (such as DDU1) and the second access network data node (such as DDU2).

[0282] Step 5: The first access network data node (such as DDU1) sends a first request message to the second access network data node (such as DDU2) based on the interface configuration information and requirement information; and receives a first response message sent by the second access network data node; wherein the first request message may be an echo request message, and the first response message may be an echo response message; specifically, for example: when the first access network data node (such as DDU1) requires the second access network data node (such as DDU2) to collaborate and / or forward data, it sends an echo request message to the second access network data node (such as DDU2), and the second access network data node (such as DDU2) replies with an echo response message to confirm that the G1 interface is established.

[0283] Step 6: The first access network data node (e.g., DDU1) uses the UP Transport Layer Information obtained in step 4 to send MAC data and information to the second access network data node (e.g., DDU2). This involves data transmission, including coordinated transmission (e.g., TB) between access network data nodes (e.g., DDUs). Specifically, the access network data nodes exchange information via the G1 interface.

[0284] It is to be noted that the relevant contents of the above embodiments can be referred to each other, and the repeated parts will not be repeated here.

[0285] From the above, the solution provided by the embodiment of the present disclosure includes: introducing a user plane logical interface G1 between access network data nodes (such as DDU), the control node maintains the interface configuration information (such as DDU list), and notifies the access network data nodes (such as DDU) to establish the G1 interface, thereby supporting direct communication between access network data nodes.

[0286] In summary, this solution introduces an access network interface creation solution, which can support the realization of: providing real-time collaborative scheduling and data transmission between communication network access network data nodes, and can be applied to 5G and 6G, especially in user-centric network architecture, to meet the real-time requirements of multi-TRP collaboration across access network data nodes, reduce the impact on user service latency and transmission, realize layered and multi-dimensional information collaboration across base station access network data nodes, and improve resource utilization efficiency.
