Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it can be diversity transmission, precoded transmission or beamforming transmission, etc.
[0176] The following first introduces the contents involved in the solution provided in the embodiment of the present application.
[0177] 4G and 5G mobile communication systems have been committed to solving the problem of low throughput of users at the cell edge under the cellular network architecture. Therefore, key technologies such as Coordinated Multiple Points (CoMP) and Multi-TRP (M-TRP) have been proposed. Figure 2 (5G network architecture):
[0178] The 5G system adopts a centralized + distributed approach to perform multi-point collaborative transmission and reception, and sinks the objects of multi-point collaboration to the transmit / receive node TRP (Transmit / Receive Point, TRP) level, supports highly dynamic collaboration, and effectively improves the throughput of users at the edge of the cell. However, it should be pointed out that, limited by the capabilities of the basic software and hardware, a single distributed unit (DU) is difficult to support a larger user scale or a wider coverage area. In many scenarios (such as ultra-dense networking), multi-TRP collaboration across DUs is also required. However, currently, multi-TRP collaboration across DUs can only be performed through the central unit (CU): DUs need to report information to the CU through the F1 interface for information collaboration, and the CU then sends it to the collaborative DU through the F1 interface (the main method is to transmit user-plane data from different DUs through different paths). However, the path delay transferred through the CU and F1 interfaces is difficult to support the collaborative transmission of DU data streams; at the same time, the terminal will also cause increased latency or data interruption when switching between DUs. Among them, Figure 2The 5GC in it stands for 5G core network (5GCore), the NG between 5GC and gNB stands for NG interface, the Xn-C between gNB and gNB-CU stands for Xn-C interface, gNB stands for 5G base station (the nextGeneration Node B), and NG-RAN stands for Next Generation Radio Access Network.
[0179] In order to solve the problem of low cell edge user rate and cell handover data delay or interruption that reduces the performance of coordinated multi-point transmission and reception under the traditional cellular access network architecture, a user-centric access network architecture (such as Figure 3 As shown): By introducing flexible cells, multiple TRPs (TRPs belonging to different DDUs) under the Distributed Data Unit (DDU) are organized to coordinate transmission and serve a user equipment (User Equipment, UE), thereby improving the user experience. Figure 3 This is a typical example of a user-centric access network (6G user-centric network architecture), specifically:
[0180] like Figure 3 As shown in the figure, a flexible cell (Flexible cell) serving the UE is composed of multiple TRPs, wherein the functions of each network element are introduced as follows:
[0181] (1) CCU (Cloud-based Control Unit), as the control plane anchor node, is responsible for control and management functions.
[0182] (2) DDU: User plane anchor point, responsible for data scheduling and transmission.
[0183] (3) TRP: TRP is a data transceiver node that performs radio frequency and some physical layer functions.
[0184] (4) Flexible cell: An area composed of one or more APs (Access Points) or TRPs with some or all of the same access and transmission parameters. The control plane unit CCU flexibly enables and configures the TRP candidate set for the terminal, that is, the coverage area is variable. The AP or TRP of a flexible cell is flexibly organized by the data plane unit DU. For any terminal, the DDU responsible for providing scheduling decisions can be called the primary DDU, and the one that only provides TRP resources and does not make scheduling decisions can be called the secondary DDU.
[0185] 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 Inter-DDU (between DDUs) TRP sets (TRP Group, TRPG) and TRP resource scheduling, and realize the coordination of different protocol layers and different dimensional information across DDUs (such as physical resource block (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.
[0186] Based on the above, the embodiments of the present application provide an information processing method, device and equipment, which are used to solve the problem that the information processing scheme for cross-access network data nodes in the prior art cannot meet the real-time requirements. Among them, the method, device and equipment are based on the same application concept. Since the principles of solving the problems by the method, device and equipment are similar, the implementation of the method, device and equipment can refer to each other, and the repeated parts will not be repeated.
[0187] The information processing method provided in the embodiment of the present application is applied to a first access network data node, such as Figure 4 As shown, including:
[0188] Step 41: Receive first information sent by a control node; the first information includes: interface configuration information, or interface configuration information and a creation indication;
[0189] Step 42: Create a user plane logical interface with the second access network data node according to the first information;
[0190] Step 43: Use the user plane logical interface to perform information coordination and / or data transmission with the second access network data node.
[0191] Among them, 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.
[0192] Among them, 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 to this. The creating of a user plane logical interface with the second access network data node according to the first information may include: interacting with the second access network data node according to 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, message parsing and processing) at both ends of the first access network data node and the second access network data node and a channel between the two ends, but is not limited to this.
[0193] The information processing method provided in the embodiment of the present application receives the first information sent by the control node; the first information includes: interface configuration information, or interface configuration information and 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 coordination and / or data transmission is performed between 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.
[0194] 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.
[0195] In this way, a user plane logical interface with the second access network data node can be accurately created. Among them, sending a first request message to the second access network data node may include: sending a first request message to the second access network data node according to the transport layer address; in addition, the first request message may carry relevant information of the interface configuration information, such as relevant information used for subsequent transmission, but is not limited to this. The GTP-TEID can be understood as a channel identifier, but is not limited to this. Among them, the transport layer address can be an IP address; the first request message can be an echo request (i.e., Echo req, response request) message, the first response message can be an echo response (i.e., Echo resp, echo response) message, the terminal identifier can be a gNB-CU UE F1AP ID, and the cell identifier can be a gNB-DU ID+PCI, but is not limited to this.
[0196] In an embodiment of the present application, 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.
[0197] 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.
[0198] 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 PCI, or a 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.
[0199] This can support unique, accurate and multi-mode representation of terminal identification and / or cell identification. Among them, the F1 interface application protocol identifier (F1AP ID) can be the gNB-CU UE F1AP ID, but is not limited to this.
[0200] In an embodiment of the present application, 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.
[0201] This allows 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 TEID. In this case, in order to achieve data transparent transmission between access network data nodes, when the MAC layer transmits data as UE data stream after DRB multiplexing, 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 of PHY are multiplexed into cell bitstream after mapping, a cell (resource) identifier is required to distinguish the data for subsequent processing.
[0202] 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 in a newly added message.
[0203] In this way, the updated interface configuration information can be received in multiple ways. Among them, "interface configuration information is carried in the F1 interface message", specifically, it can include: adding interface configuration information to the current F1 interface message, such as adding a user plane transport layer information list (UP Transport Layer Information list); "interface configuration information is carried in a newly added message", specifically, it can include: adding the initial creation message and update message of the control node to carry the interface configuration information, but it is not limited to this. In addition, the subsequent first access network data node can continue to create the user plane logical interface according to the updated interface configuration information, which is not limited here.
[0204] The control node is a central unit CU or a cloud control unit CCU.
[0205] This can support the application of this solution to a variety of 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 to the first cloud control unit CCU; the second access network data node is connected to the second CU or to 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.
[0206] In an embodiment of the present application, 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 primary access network data node and the auxiliary access network data node in the collaborative TRPG.
[0207] In this way, it is possible to support one-time instruction to create a user plane logical interface between multiple access network data nodes in multiple situations.
[0208] The present application also provides an information processing method, which is applied to a control node, such as Figure 5 As shown, including:
[0209] Step 51: Determine interface configuration information between the first access network data node and the second access network data node;
[0210] Step 52: According to the interface configuration information, send first information to the first access network data node, 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.
[0211] Among them, 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.
[0212] The information processing method provided in the embodiment of the present application determines the interface configuration information between the first access network data node and the second access network data node; sends the first information to the first access network data node according to the interface configuration information, or sends the 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 the 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.
[0213] Among them, the interface configuration information includes: a transport layer address and a GTP-TEID; and / or, the first access network data node is any one of all the access network data nodes connected to the control node, and the second access network data node is any one of all the 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.
[0214] This can support the first access network data node to accurately send the 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 second access network data node.
[0215] In an embodiment of the present application, 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.
[0216] This can support the first access network data node to accurately create 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.
[0217] 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 PCI, or a 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.
[0218] This can support unique, accurate and multi-mode representation of terminal identification and / or cell identification. Among them, the F1 interface application protocol identifier (F1AP ID) can be the gNB-CU UE F1AP ID, but is not limited to this.
[0219] In an embodiment of the present application, 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.
[0220] This can support accurate data transmission between the first access network data node and the second access network data node.
[0221] 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 an F1 interface message, or carried in a new message.
[0222] In this way, the updated interface configuration information can be transmitted in multiple ways. Wherein, the updating of the interface configuration information may include: updating the interface configuration information when the TRPG is updated, but is not limited to this. In addition, of course, the present application may also include: sending the updated interface configuration information to the second access network data node, which is not limited here.
[0223] The interface configuration information corresponds to at least one terminal.
[0224] This can support multiplexing of the interface configuration information.
[0225] In an embodiment of the present application, 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 primary access network data node and the auxiliary access network data node in the collaborative TRPG.
[0226] In this way, it is possible to support one-time instruction to create a user plane logical interface between multiple access network data nodes in multiple situations.
[0227] It is to be noted here that the related contents of the first access network data node and the control node mentioned above can refer to each other, and the repeated contents will not be repeated.
[0228] The information processing method provided in the embodiments of the present application is described below with examples.
[0229] In response to the above technical problems, an embodiment of the present application provides 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 send / receive nodes (Transmit / Receive Point, TRP) across access network data nodes through control node operation in the communication network 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 use different tunnel identifiers for transmission at different protocol layers.
[0230] Specifically, this plan includes the following contents:
[0231] 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 coordination and data transmission, where the G1 interface (i.e., user plane logical interface G1) can be used Figure 6 The protocol stack shown is used for information transmission. Figure 6The User plane PDUs in it means user plane protocol data units, GTP-U means the GPRS (General Packet Radio Service) tunnel protocol (GPRS Tunnel Protocol) layer at the user plane, UDP means the User Datagram Protocol (User Datagram Protocol) layer, IP means the network protocol layer, Data link layer means the data link layer, and Physical layer means the physical layer.
[0232] a) Based on the network architecture (5G or 6G), a G1 interface can be established between different access network data nodes connected under the control node; the control node of this solution is only responsible for the maintenance and notification of necessary information when the G1 interface between access network data nodes is first established, where the G1 interface is for subsequent transmission between access network data nodes and has nothing to do with the control node; in the prior art, any message to be transmitted between access network data nodes needs to be transferred through the control node. The control node can be a 5G CU or a 6G CCU, and the access network data node can be a DU or a DDU, which is not limited here.
[0233] b) Further, the G1 interface may also be extended to access network data nodes under different control nodes. The two access network data nodes that interact may be nodes under the same network architecture or nodes under different network architectures, which is not limited here.
[0234] 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.
[0235] 3. The interface configuration information is used to instruct the creation of a user plane logical interface between access network data nodes within the first range, and specifically, may include: a G1 interface may be established in access network data nodes in different ranges after the user accesses, for example:
[0236] a) All access network data nodes connected to the same control node, such as: between all DDUs connected under the CCU;
[0237] b) All access network data nodes involved in the cooperative transceiver point set TRPG, such as: between all DDUs involved in the cooperative TRPG according to the network configuration;
[0238] c) A primary access network data node and an auxiliary access network data node in a collaborative TRPG, such as between a primary and auxiliary DDU in a collaborative TRPG according to network configuration;
[0239] Among them, the above b) / c) is applicable to cooperative DDUs determined in other forms in a non-user-centric network, but is not limited to this.
[0240] 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 according to the access network data node for establishing the G1 interface and the necessary information required, including the Transport Layer Address (transport layer address) and GTP-TEID (GPRS Tunneling Protocol Tunnel Endpoint Identifier) corresponding to each access network data node; specifically, for example: the control node takes CCU as an example, and the access network data node takes DDU as an example, and the CCU establishes and maintains a list DDU list according to the DDU for establishing the G1 interface and the necessary information required (for the case where the DDU is configured with TRPG, it is also necessary to report to the CCU first), including the Transport Layer Address (transport layer address) and GTP-TEID (GPRS Tunneling Protocol Tunnel Endpoint Identifier) corresponding to each DDU, and transmits it to the DDU through the F1 interface; specifically:
[0241] a) Based on 3a) or 3b), the DDU list can be sent to all or cooperating DDUs;
[0242] b) Based on 3c), only the DDU list needs to be informed to the master DDU;
[0243] 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 TRPG is updated, CCU synchronously updates the DDU list to DDU (which can be executed according to a) and b) in 4).
[0244] 6. The first access network data node uses the user plane logical interface to perform target data transmission according to the GTP-TEID; for example: the first access network data node takes DDU as an example, and the DDU receives different GTP data packets according to the position of the protocol stack corresponding to the interface or the content of the GTP-TEID, such as Figure 7As shown in the figure (in the figure, DDU-L represents the distributed data unit low-layer node, RLC represents the radio link control layer, MAC represents the media access control layer, PHY represents the physical layer, DRB represents the data radio bearer, TB represents the transmission block, and Bitstream represents the bit stream), different unique corresponding GTP-TEIDs are used for data transmission:
[0245] 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 MAC PDU (Multiple Access Channel Protocol Data Unit) and necessary information, GTP-TEID corresponds to the unique UE ID of the terminal to which the data between DDUs belongs. Specifically: Figure 7 The first DRB1 and the first DRB2 in the RLC represent the data radio bearer 1 and the data radio bearer 2 corresponding to UE1 in the RLC, respectively. The second DRB1 represents the data radio bearer 1 corresponding to UE2 in the RLC. The third DRB1 represents the data radio bearer 1 corresponding to UE3 in the RLC. UE1TB represents the transmission block after multiplexing all the data radio bearers of UE1 in the MAC. UE2 TB represents the transmission block after multiplexing the data radio bearers of UE2 in the MAC. UE3 TB represents the transmission block after multiplexing the data radio bearers of UE3 in the MAC. TB(UE ID1) represents the transmission channel between two DDU-L MACs whose GTP-TEID corresponding to UE ID 1 is TEID 1. TB(UE ID2) represents the transmission channel between two DDU-L MACs whose GTP-TEID corresponding to UE ID 2 is TEID 2.
[0246] b) GTP-TEID corresponds to the first target identifier. When the target data includes the physical layer bitstream data of a terminal, the first target identifier is the terminal identifier; for example, when the interface transmits a single UE physical layer bitstream and necessary information, GTP-TEID corresponds to the unique UE ID of the terminal to which the DDU data belongs; for example, Figure 7 Bitstream(UE ID1) in the bitstream indicates that the bitstream belonging to UE ID1 between two DDU-L PHYs corresponds to the transmission channel with GTP-TEID TEID 1, and Bitstream(UE ID2) indicates that the bitstream belonging to UEID2 between two DDU-L PHYs corresponds to the transmission channel with GTP-TEID TEID TEID2;
[0247] 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 id (physical layer resource id) of the cell to which the DDU data belongs; specifically: Figure 7 Cell ID1 in the cell indicates the physical layer resource 1 carried by UE1TB, UE2TB and UE3TB after being processed in PHY, and Bitstream (cell ID1) indicates the transmission channel whose GTP-TEID is TEID 1 corresponding to the bit stream carried by cell ID1 between two DDU-L PHYs.
[0248] in, Figure 7 TRP2 and TRP3 in the DU may form a TRPG, thereby establishing an inter-DU interface to assist TRPGs (TRP2 and 3) in serving the UE together, but this is not limited to this.
[0249] 7. Based on 6, GTP-TEID has the following correspondence:
[0250] a) Based on 6a) or 6b), 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; wherein the F1 interface application protocol identifier may be a gNB-CU UE F1AP ID, which may be specifically understood as: using gNB-CU UE F1AP ID or Cell id+C-RNTI (Cell-RadioNetworkTemporaryIdentifier, cell radio network temporary identifier) to represent the UE ID;
[0251] b) Based on 6c), 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; wherein the access network data node identifier can be a gNB-DU ID, which can be specifically understood as: using gNB-DU ID+PCI (Physical Cell Identifier) or NR Cell Global Identifier (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.
[0252] 8. The interface configuration information corresponds to at least one terminal; for example, for multiple UEs, the network can maintain a separate DDU list for each UE or maintain a total DDU list.
[0253] The following is a specific example to illustrate this solution.
[0254] Embodiment 1: A G1 interface is established under a 5G architecture, wherein a 5G CU is used as an example for the control node and a 5G DU is used as an example for the access network data node;
[0255] like Figure 8 As shown, the solution of this embodiment may specifically include the following steps:
[0256] Step 1: After the control node (such as gNB-CU) and the access network data node (such as gNB-DU) are started, the access network data node (such as gNB-DU) initiates the F1 interface establishment process, and the control node (such as gNB-CU) obtains the access network data node identifier, Transport Layer Address (IP addr) and PCI of all connected access network data nodes (such as gNB-DU). Among them, the access network data node identifier can be the gNB-DU ID.
[0257] Step 2: After the network initialization is completed, the UE accesses the first access network data node (such as gNB-DU1) and establishes or updates the user context. The control node (such as gNB-CU) obtains the F1 interface application protocol identifier (such as gNB-CU UE F1AP ID) as the UE ID, that is, the UE context is established / updated and the UE ID is obtained; the F1 interface application protocol identifier (such as gNB-CU UE F1AP ID) is an F1 interface parameter, which can be used to uniquely identify a UE in a control node (such as gNB-CU) (including multiple connected DUs). Based on this, this solution can establish a transmission channel between access network data nodes (such as gNB-DU) and can distinguish and restore data of different UEs at the MAC layer of the receiving access network data node (such as gNB-DU).
[0258] 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 (user plane transport layer information, including Transport Layer Address and GTP-TEID) of each access network data node (e.g., gNB-DU); specifically:
[0259] 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; for example, when MAC layer data is transmitted between access network data nodes (such as gNB-DU), or when physical layer data is transmitted between access network data nodes (such as gNB-DU) for a single UE, a GTP-TEID corresponding to the UE ID is generated;
[0260] b) 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 multiple UEs transmit physical layer data between access network data nodes (such as gNB-DU), a GTP-TEID corresponding to the access network data node identifier (such as gNB-DU ID) + PCI is generated;
[0261] Among them, GTP-TEID is generated by the control node (such as gNB-CU). The control node (such as gNB-CU) can generate GTP-TEID for the above two cases, or it can predict in advance what kind of data is transmitted between the access network data nodes (such as gNB-DU) to generate the corresponding GTP-TEID, which is not limited here.
[0262] 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.
[0263] Step 5: The first access network data node (such as gNB-DU1) sends a first request message to the second access network data node (such as gNB-DU2) according to the interface configuration information and the requirement information; and receives a first response message sent by the second access network data node (such as gNB-DU2); wherein the first request message may be an echo request (i.e., Echo req, response request) message, and the first response message may be an echo response (i.e., Echo resp, response response) message; for example: when the first access network data node (such as gNB-DU1) needs the second access network data node (such as gNB-DU2) to coordinate and / or forward data, it sends an echo request (i.e., Echo req, response request) message (to request confirmation of the G1 interface), and gNB-DU2 replies with an echo response (i.e., Echo resp, response response) message to confirm that the G1 interface is established.
[0264] 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 cooperative information or data to the receiving end of the second access network data node (e.g., gNB-DU2) corresponding to the Transport Layer Address through the GTP Tunnel indicated or identified by the GTP-TEID; that is, data transmission is performed, including cooperative transmission (e.g., TB or bitstream) between access network data nodes (e.g., gNB-DU). Specifically, the access network data nodes can exchange information through the G1 interface.
[0265] Among them, 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 sending function of gNB-DU1 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, and sending the echo request in step 5 also needs to know the IP address of the other end, and the TEID can use the default value (such as 0).
[0266] Embodiment 2: Establishing a G1 interface under a 6G architecture, wherein the control node takes a 6G CCU as an example, and the access network data node takes a 6G DDU as an example;
[0267] like Fig. 9 As shown, the solution of this embodiment may specifically include the following steps:
[0268] 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).
[0269] Step 2: After the network initialization is completed, the UE accesses the first access network data node (such as DDU1); the control node (such as CCU) configures TRPG for the UE, and determines the interface configuration information (such as establishing a DDU list) according to the cooperative 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), wherein the generated GTP-TEID and CellID 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 main access network data node (such as the main DDU).
[0270] Step 3: The control node sends the first information to the first access network data node according to 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.
[0271] 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 the 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 (i.e., Echo req, response request) message, and the first response message may be an echo response (i.e., Echo resp, response response) message; for example: when the first access network data node (i.e., the primary access network data node, such as DDU1-primary DDU) needs the second access network data node (i.e., the secondary access network data node, such as DDU2-secondary DDU) to coordinate 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 echoresponse message to confirm that the G1 interface is established.
[0272] 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 in 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); that is, data transmission is performed, including collaborative transmission (such as bitstream, etc.) between access network data nodes (such as DDU). Specifically, information exchange can be performed between access network data nodes through the G1 interface.
[0273] 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 main access network data node, such as DDU1-main DDU) to update G1, and the subsequent steps are consistent with steps 4-5 and will not be repeated here.
[0274] Embodiment 3: Establishing a G1 interface under a 6G architecture, wherein the control node takes a 6G CCU as an example, and the access network data node takes a 6G DDU as an example;
[0275] like Fig.10 As shown, the solution of this embodiment may specifically include the following steps:
[0276] 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) of all connected access network data nodes (such as DDU).
[0277] 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, and the control node (such as CCU) obtains the unique UE ID of the UE under the current control node (such as CCU) connection.
[0278] 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.
[0279] Step 4: The control node sends the first information to the first access network data node according to 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).
[0280] 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) according to the interface configuration information and the demand 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 (i.e., Echo req, response request) message, and the first response message may be an echo response (i.e., Echo resp, response response) message; for example: when the first access network data node (such as DDU1) needs the second access network data node (such as DDU2) to collaborate and / or forward data, it sends an echorequest message to the second access network data node (such as DDU2), and the second access network data node (such as DDU2) replies with an echoresponse message to confirm that the G1 interface is established.
[0281] Step 6: The first access network data node (such as DDU1) uses the UP Transport Layer Information obtained in step 4 to send MAC data and information to the second access network data node (such as DDU2); that is, data transmission is performed, including collaborative transmission (such as TB, etc.) between access network data nodes (such as DDU). Specifically, information exchange can be performed between access network data nodes through the G1 interface.
[0282] It is to be noted that the relevant contents of the above embodiments can be referenced to each other, and the repeated contents will not be repeated here.
[0283] From the above, the solution provided by the embodiment of the present application 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.
[0284] 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, and realize layered and multi-dimensional information collaboration across base station access network data nodes to improve resource utilization efficiency.
