Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of communications, and more particularly to a communication method and related equipment. Background Technology
[0002] Existing short-range wireless communication typically involves management nodes and terminal nodes. Management nodes are referred to as G nodes, and terminal nodes as T nodes. Interoperating G nodes and T nodes form a short-range communication domain. G nodes are the nodes that send data scheduling information to the access layer of the short-range wireless communication system, and they provide access layer services such as connection management, resource allocation, and information security to the T nodes within their communication domain. Short-range communication domains offer low power consumption and low cost between nodes, but their communication distance is relatively limited. Bluetooth and WiFi are examples of short-range wireless communication technologies.
[0003] Compared to short-range wireless communication, long-range communication systems, such as 5G cellular networks, can provide macro coverage, serving user terminals within that macro coverage area. If the short-range communication domain and cellular network communication system can be integrated (hereinafter referred to as integrated communication system), it is hoped that low-cost, long-distance data transmission from terminals can be achieved. However, current integrated communication systems struggle to manage nodes within the short-range communication domain, making the integration of the short-range communication domain and cellular network communication system difficult.

[0102] The technical solutions of this application will now be described with reference to the accompanying drawings. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0103] For ease of understanding, the following examples illustrate some concepts related to the embodiments of this application for reference. As follows:
[0104] The communication systems in this application include: Global System of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), 5th Generation (5G) cellular communication systems or New Radio (NR) millimeter-wave communication systems, 6th Generation (6G) systems, various existing short-range communication systems (e.g., Bluetooth, WiFi, vehicle-mounted general short-range wireless communication systems, star-flash short-range communication systems, etc.), future evolved short-range communication systems, or general short-range communication systems, etc.
[0105] The node in this application is an electronic device with communication capabilities, also known as a communication node. For example, a node can include independent devices such as handheld terminals, vehicles, in-vehicle equipment, network-side equipment, user equipment, access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, wireless communication equipment, user agents, or user devices, or it can be a component (e.g., a chip or integrated circuit) contained within an independent device. A node can be any possible smart terminal device (e.g., a mobile phone), smart transportation equipment (e.g., vehicles, drones), smart manufacturing equipment, smart home equipment (e.g., large screens, speakers), etc. In one possible scenario, within a vehicle, the node can also be a battery management system and the battery in the battery pack.
[0106] For example, when the node is an in-vehicle device, it can be a cockpit domain device or a module of a cockpit domain device, such as one or more modules such as a cockpit domain controller (CDC), camera, screen, microphone, audio, electronic key, keyless entry or start system controller, etc.
[0107] The nodes in this application can be applied to the aforementioned communication systems. The nodes in the embodiments of this application can be applied to various application scenarios, such as the following: mobile internet (MI), industrial control, self-driving, transportation safety, internet of things (IoT), smart city, smart home, or intelligent manufacturing, etc.
[0108] In certain application scenarios or network types, devices with similar communication capabilities may not be called nodes. However, for ease of description, electronic devices with communication capabilities are collectively referred to as nodes in this application embodiment.
[0109] Taking a short-range communication system as an example, a short-range communication system includes terminal nodes, management nodes, and gateway nodes. The management node manages the terminal nodes, has the function of allocating resources, and is responsible for allocating resources to the terminal nodes. The terminal nodes follow the scheduling of the management node and use the resources allocated by the management node to communicate with the management node and / or other nodes. The gateway node can connect to the management node and acts as a communication bridge between this communication system and other communication systems.
[0110] In some specific implementation scenarios, the management node can also be called a G node, master node, or control node, and the terminal node can also be called a T node or slave node. The communication link from the G node to the T node can be called a C link or downlink, and the communication link from the T node to the G node can be called a T link or uplink.
[0111] The above exemplary description of the concepts can be applied to the embodiments described below.
[0112] In a system that integrates short-range wireless communication systems with 5G cellular networks, the 5G core network needs to acquire relevant information reported by the terminal nodes in order to better perceive and manage them, thus meeting the needs of typical applications such as smart manufacturing, industrial field networks, and robotic arm motion control.
[0113] To address the aforementioned technical problems, this application provides a communication method that enables information reporting by a first node to meet node management requirements. The communication method in this application is applied to a first communication system and a second communication system, which can be either of the aforementioned communication systems. Specifically, the first communication system can be any short-range communication system, and the second communication system can be any other communication system with a longer communication distance than the first communication system. Figure 1a , Figure 1b This is a schematic diagram of the structure of a first communication system and a second communication system provided in an embodiment of the present invention. (Refer to...) Figure 1a In the various embodiments of this application, the first communication system is exemplified by a short-range communication system 102 (such as a general short-range communication system), while the second communication system is exemplified by a 5G cellular communication system 101 to specifically describe the above communication method. It is worth noting that the communication method of the embodiments of this application is not limited to applications in short-range communication systems and 5G cellular communication systems.
[0114] Specifically, Figure 1a The short-range communication system 102 includes a T node, a G node, and a gateway node TNGF. The T node and the G node communicate with each other through the SparkLink short-range communication system L2 interface. The T node also communicates with the gateway node TNGF through the NWt interface. The G node and the gateway node TNGF communicate with each other through the Ta interface.
[0115] More specifically, Figure 1a In this context, the T node is the terminal node in the short-range communication system. Its basic service layer has 5G converged functional units, and these units support non-access-stratum (NAS) functions. The T node is responsible for the following functions:
[0116] Access to the 5G core network via a trusted short-range access network;
[0117] The status of the short-range communication system is measured and reported according to the configuration of the 5G core network. The status includes the status of the T node and the link status of the link where the T node is located. The link where the T node is located includes the link between the T node and the G node, or the link between the T node and the 5G core network.
[0118] Service interactions are configured according to the Quality of Service (QoS) policy of the 5G core network.
[0119] It should be understood that the above description of the functions of the T node is provided for ease of understanding only and is not intended to limit the T node. In specific implementation, the functions of the T node may be reduced or increased according to the actual situation.
[0120] and Figure 1a In this context, the G node refers to the G node authenticated by the 5G core network, which is also the management node of the short-range communication system deployed by the operator. It is the node that sends data scheduling information to the access layer of the short-range communication system, providing access layer services such as connection management, resource allocation, and information security to the T nodes under its coverage. It can provide short-range access services to the terminal nodes under its coverage according to the instructions of the 5G core network, and it can establish a trusted connection with the 5G core network through TNGF. The basic service layer of the G node has 5G converged functional units. The G node is responsible for the following functions:
[0121] It provides 5G converged services, enabling T nodes to perform service discovery and access;
[0122] Perform identity authentication on T nodes that support 5G convergence functionality;
[0123] The status of the short-range communication system is measured and reported according to the configuration of the 5G core network;
[0124] Based on the QoS policy configuration of the 5G core network, resources are allocated and scheduled for the T nodes under its coverage.
[0125] Provides air interface data transmission services for T nodes, used for interaction between T nodes and TNGF, and between T nodes and the control plane and user plane of the 5G core network;
[0126] Assign IP addresses to T nodes for control plane and user plane transmission and addressing in short-range communication systems;
[0127] During remote transmission, provide T-nodes with QoS policy configuration information for short-range communication system data transmission;
[0128] When the 5G core network determines the QoS policy configuration information of node T, it forwards the QoS policy configuration information issued by the 5G core network to node T.
[0129] It should be understood that the above description of the functions of the G node is provided for ease of understanding only and is not intended to limit the T node. In specific implementation, the functions of the G node may be reduced or increased according to the actual situation.
[0130] in addition, Figure 1a The gateway node TNGF in the system is responsible for the following functions:
[0131] NAS messages between the relay T-node and the 5G core network;
[0132] GTP-U tunnel information transmitted between the control plane and user plane of the T node;
[0133] Forward QoS policy configuration information of the 5G core network to the T node and provide QoS information updates;
[0134] Provide QoS policy configuration for short-range communication to G nodes;
[0135] It supports AAA, which stands for Authentication, Authorization, and Accounting. It is a security management mechanism for access control in network security, providing three security services: authentication, authorization, and accounting.
[0136] It should be understood that the above description of the functions of the gateway node TNGF is provided for ease of understanding only and is not intended to limit the T node. In specific implementation, the functions of the gateway node TNGF may be reduced or increased according to the actual situation.
[0137] Figure 1aIn the 5G cellular communication system 101, network elements (i.e., functional entities) include: Network Slice Selection Function (NSSF), Network Exposure Function (NEF), Network Repository Function (NRF), Policy Control Function (PCF), Unified Data Management (UDM), Application Function (AF), Network Slice-specific and SNPN Authentication and Authorization Function (NSSAAF), Authentication Server Function (AUSF), Access Mobile Function (AMF), Session Management Function (SMF), Service Communication Proxy (SCP), Network Slice Admission Control Function (NSACF), and User Plane Function (User Plane). Plane Function (UPF) network elements, xNF network elements, or one or more data networks (DNs). DNs include carrier services, internet access, or third-party services.
[0138] Among them, the NSSF network element determines the network slice instance that the UE is allowed to access based on the slice selection auxiliary information and subscription information of the user equipment (UE).
[0139] NEF elements are used to expose the capabilities of various network functions (NFs) and transform internal and external information. They are used in edge computing scenarios.
[0140] NRF network elements provide registration and discovery functions, enabling network functions to discover each other and communicate through application programming interfaces (APIs).
[0141] PCF network elements are used to provide policy rules for control plane functions. The 5G core network control plane functions, responsible for policy control, simply put, primarily manage the QoS of various service data flows within the 5G core network.
[0142] UDM network elements are responsible for AKA (Authentication and Key Agreement) protocol authentication, user identification, access authorization, registration, mobility, subscription, SMS management, etc.
[0143] Application layer (AF) refers to various services, which can be internal applications of the operator or third-party AFs (such as video servers and game servers).
[0144] The NSSAAF network element is used to authenticate and authorize users accessing 5G network slices.
[0145] AUSF network elements are used to implement 3GPP and non-3GPP access authentication.
[0146] The AMF network element is used to perform registration, connection, reachability, and mobility management. It provides a session management message transmission channel for the UE and SMF network element, provides authentication and authorization functions for user access, and serves as the core network control plane access point for the terminal and radio.
[0147] The SMF network element is responsible for tunnel maintenance, Internet Protocol (IP) address allocation and management, username function selection, policy enforcement and QoS control, billing data collection, roaming, etc.
[0148] As an important network element related to Hypertext Transfer Protocol (HTTP) message forwarding in the 5G core network, the SCP network element only supports flexible routing and indirect communication functions.
[0149] NSACF network elements are used for admission control based on the number of connected users in Radio Resource Control (RRC) mode, which is supported by the user and the network slice group.
[0150] UPF network elements are responsible for packet routing and forwarding, policy enforcement, traffic reporting, and QoS processing. Among these, UPF network elements include PMF units.
[0151] In this embodiment, the xNF network element is a newly added functional entity in the 5G cellular communication system. In this case, the xNF network element is the first functional entity, which may only support the processing of node status information of the T node in the short-range communication system and the adjustment of node adjustment parameters (referring to node-related adjustment parameters, such as node status update information, QoS policy configuration information, or node status reporting policy, etc.), or it may only support the processing of link status information and the configuration of link detection policies; of course, it may also simultaneously support the processing of node status information and link status information of the T node, as well as the adjustment of node adjustment parameters and link detection policies (node adjustment parameters and link detection policies are i.e., control policy information). The xNF network element provides services to other network elements through the service interface Nxnf. (Refer to...) Figure 1b xNF network elements include user plane and control plane functions. The first information of a T node (including node status information and / or link status information) can be transmitted via either the user plane or the control plane. User plane transmission requires the T node to establish an IP connection with the xNF network element, incurring additional signaling overhead compared to the control plane. Therefore, the first information of the T node is preferably transmitted via control plane functions. More specifically, the first information can be transmitted via the control plane in the form of a container, or it can be configured for user plane transmission based on the TR-069 transport protocol or based on the PMF user plane. The TR-069 transport protocol provides a general framework, message specifications, management methods, and data models for managing and configuring home network devices in next-generation networks. PMF-based user plane transmission involves sending the first information to the PMF unit of the UPF network element, and then forwarding it to the xNF network element.
[0152] The PMF network element supports end-to-end link detection between the terminal and the 5G core network, as defined in existing technologies and will not be repeated here. In this embodiment, the PMF function is extended to support at least short-range measurement, and optionally, the detection of the terminal node's status and the end-to-end link status (i.e., the link where the terminal node is located, including the link between the terminal node and the management node, or the link between the terminal node and the 5G core network). The specific PMF protocol can be found in existing technologies and is not specifically limited here.
[0153] It is easy to understand that, Figure 1a The components of short-range communication systems and 5G cellular communication systems can be fewer or more, and will not be elaborated on in detail.
[0154] It is worth noting that in the short-range communication system 102 and the 5G cellular communication system 101, the specific process of the T node reporting the first information to the xNF network element and the T node receiving the control policy information sent by the xNF network element is described in the following records.

Figure 2 , Figure 4 , Figure 6 , Figure 9 The different orders presented may be executed, and it is possible that they are not intended to be executed. Figure 2 , Figure 4 , Figure 6 , Figure 9 All operations within.
[0156] This application provides a communication method, referencing... Figure 2 , Figure 2 This is an interactive flowchart of a communication method provided in an embodiment of the present invention. The communication method includes at least the following steps:
[0157] Step S201: The first node obtains the first information of the first node in the first communication system.
[0158] Specifically, the first information includes one or more of the following: the status information of the first node, or the status information of the first link. The status information of the first node refers to information related to the first node (the relevant content of the status information of the first node will be described in detail below).
[0159] The first link is the link through which the first node communicates; for example, the first node is one end of the first link. The status information of the first link refers to information related to the link status of the first link (the details of the status information of the first link will be described in detail below).
[0160] Optionally, the first node can acquire the first information in various ways. For example, the first information can be detected by the first node. For instance, the first node can detect the channel quality when communicating based on the first link, thereby obtaining detection result information related to the channel quality, and the first information can include this detection result information related to the channel quality. Alternatively, the status information of the first link can be received by the first node from other nodes. For instance, the first node can receive channel quality indication information sent by the peer, thereby obtaining quality indication information, and the first information can include this quality indication information.
[0161] Step S202: The first node sends first information to the first functional entity in the second communication system through a first method.
[0162] Accordingly, the first functional entity receives the first information from the first node in the first communication system.
[0163] The first method refers to sending the first information. It should be noted that during the process of the first node sending the first information to the first functional entity in the second communication system, it may be forwarded by other nodes. This application does not limit the number of nodes involved in the intermediate forwarding. For example, the first node can directly send the first information to the first functional entity in the second communication system (i.e., experiencing 0 forwards), or it can indirectly send the first information to the first functional entity in the second communication system (the first node forwards the first information to the first functional entity through other devices, i.e., experiencing one or more forwards).
[0164] Therefore, by utilizing the communication method of the embodiments of this application, the functional entity in the second communication system can obtain the information of the node in the first communication system, thereby enabling the second communication system to perceive and manage the node of the first communication system, that is, to realize the information reporting of the first node, so as to meet the management needs of the first node, which is conducive to improving the fusion effect of the first communication system and the second communication system.
[0165] Optionally, the first node sends the first information to the second functional entity in the second communication system, so that the second functional entity forwards the first information to the first functional entity.
[0166] Accordingly, the second functional entity receives the first information from the first node and sends the first information back to the first functional entity. The second functional entity is the functional entity in the second communication system that performs information forwarding.
[0167] In some possible implementations, the status information of the first node includes one or more of the following: hardware version information, software version information, or node power information. Hardware version information refers to the version information of the hardware in the first node, which can be divided into major versions (e.g., V1.0 and V2.0) and minor versions (V1.1, V1.2, V2.1, V2.2). Software version information refers to the version information of the software in the first node, which can be divided into large-data-volume versions (i.e., full versions) and small-data-volume versions (e.g., patches). Of course, the status information of the first node includes, but is not limited to, the information listed above.
[0168] In some possible implementations, the first communication system further includes a management node for the first node. This management node is a trusted management node, meaning it has completed registration and authentication in the second communication system and is used to manage the first node. The first communication system may include more than one management node, each managing one or more subordinate first nodes. The second communication system also includes a third functional entity, which is a functional entity with a PMF unit, specifically used to parse the received PMF information (i.e., the first information encapsulated using the PMF protocol) from the first node. The state information of the first link includes a first state measurement and / or a second state measurement. The first state measurement is the link state measurement between the first node and its corresponding management node, and the second state measurement is the link state measurement between the first node and the second communication system. The link state measurement between the first node and the second communication system can be the link state measurement between the first node and the first functional entity and / or the link state measurement between the first node and the third functional entity, etc. Of course, the state information of the first link includes, but is not limited to, the information listed above.
[0169] In some possible implementations, the first state measurement includes at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), Channel Quality Indication (CQI) value, Precoding Matrix Indication (PMI) value, or Rank Indication (RI) value. Of course, the first state measurement includes, but is not limited to, the information listed above. In practice, when transmitting the first state measurement, the timestamp of when the first state measurement data was obtained can also be sent to the first functional entity.
[0170] CQI is used to reflect the channel quality of the Physical Downlink Shared Channel (PDSCH). It uses a number from 0 to 15 to represent the PDSCH channel quality, with 0 indicating the worst quality and 15 indicating the best quality.
[0171] The RI value refers to the rank of the channel impulse response (H) in both open-loop and closed-loop spatial multiplexing transmission modes. That is, RI = Rank(H). It serves as a reference for data transmission capacity, characterizing the quality of channel conditions or terminal capabilities.
[0172] PMI is used to indicate the index of the codebook set.
[0173] In some possible implementations, the second state measurement includes one or more of the following: end-to-end round-trip time (RTT), packet loss rate, or jitter. Of course, the second state measurement includes, but is not limited to, the information listed above. Similarly, in practice, when sending the second state measurement, the timestamp of when the second state measurement data was obtained can also be sent to the first functional entity.
[0174] For example, the information unit settings of the first information are shown in Table 1 below:
[0175] Table 1 Information Units of the First Information
[0176] Information unit type Status Format Length (bytes) First information message identifier Message Type Required value 1 Status information of the first node Node status information Optional Length, type, and value Adjustable Status information of the first link Link status detection information Optional Length, type, and value Adjustable
[0177] In this table, the first information of the first node can be set according to the order of information units in Table 1. The message identifier of the first information is used to identify that subsequent data sent belongs to the first information, i.e., to identify the data type. "Length" in the table refers to the data length of the information unit. Taking the status information of the first node as an example, this refers to the data length of the status information of the first node. "Type" refers to the data type of the information unit, and "Value" refers to the specific value corresponding to the information unit. Similarly, taking the status information of the first node as an example, this refers to the data type of the status information of the first node and the specific node status detection value, such as the node's battery level. Finally, "Adjustable" in Table 1 means that the data length of the corresponding information unit can be set and adjusted according to the actual situation.
[0178] Optionally, the first information can be sent in the form of a small data packet accompanying the data. It is easy to understand that the form of sending the first information is not limited to small data packets accompanying the data, and there is no particular limitation on its form.
[0179] In some possible implementations, refer to Figure 2 The communication methods also include:
[0180] Step S203: The first node receives control strategy information from the first functional entity. The control strategy information is used to configure the first node.
[0181] Accordingly, the first functional entity sends control policy information to the first node. In a specific design, when determining the control policy information to send to the first node, the first functional entity can determine the control policy information based on the first node's first information, or it can determine the control policy information through other methods; no particular limitation is made here. It should be noted that during the process of the first functional entity sending the control policy information to the first node, it may be forwarded through other nodes; this application does not limit the number of nodes traversed during intermediate forwarding. In an optional design, the second functional entity receives the control policy information from the first functional entity, and then forwards the control policy information to the first node.
[0182] In this embodiment of the invention, the first functional entity configures the information of the first node by issuing control policy information. The first functional entity can manage the status of the first node or the status detection policy of the communication link, thus enabling the management of terminal nodes, improving resource utilization, and enhancing the integration effect of the first and second communication systems. Further, the control policy information includes one or more of the following: node status update information, QoS policy configuration information, node status reporting policy, or link status detection policy. Of course, the control policy information includes, but is not limited to, the information listed above.
[0183] The node status update information includes one or more of the following: node configuration parameter information and update information on the status information of the first node. Update information on the status information of the first node may include, for example, node hardware version update information or node software version update information. Node configuration parameter information refers to one or more of the relevant configuration information for the first node, such as power-on / off management information or sleep state management information. Power-on / off management information is the power-on / off control information for the first node, while sleep state management information is the sleep state control information for the first node. QoS policy configuration information is used to configure the QoS policy for the first node. The node status reporting policy is the reporting policy corresponding to the status information of the first node. Optionally, the node status reporting policy includes one or more of the following: reporting object, reporting period, or event parameters. Finally, the link status detection policy is the detection policy corresponding to the status information of the first link. Optionally, the link status detection policy includes at least one of the following: measurement object, reporting object, reporting threshold, reporting period, or event parameters.
[0184] For example, the information unit settings for control strategy information are shown in Table 2 below:
[0185] Table 2 Information Units of Control Strategy Information
[0186]
[0187]
[0188] The control strategy information can be set according to the order of the information units in Table 2. The control strategy information message identifier is used to identify that the subsequently sent data belongs to the control strategy information, i.e., to identify the data type. "Length" in the table refers to the data length of the information unit. Taking node status update information as an example, this refers to the data length of the node status update information. "Type" refers to the data type of the information unit, and "Value" refers to the specific value of the information unit. Similarly, taking node status update information as an example, this refers to the data type of the node status update information and the specific node status update value, such as the node hardware version update value. Finally, "Adjustable" in Table 2 means that the data length of the corresponding information unit can be set and adjusted according to the actual situation.
[0189] In some possible implementations, before the first node sends the first information to the first functional entity, the communication method in this embodiment of the invention may further include:
[0190] The first node receives the transmission mode indication information, which is used to indicate the first mode.
[0191] Accordingly, the first functional entity sends the aforementioned transmission method instruction information to the first node.
[0192] In this embodiment of the invention, a transmission mode indication information is used to enable the first node to determine, based on the indication information, which first mode to use to send the first information to the first functional entity. Specifically, the first mode includes three types: a control plane transmission mode, a user plane transmission mode based on the first functional entity, or a PMF (Performance Measurement Function) user plane transmission mode. Of course, the first mode includes, but is not limited to, the modes listed above. The control plane transmission mode is a NAS-based control plane transmission mode, while the PMF user plane transmission mode is a PMF protocol-based user plane transmission mode.
[0193] Correspondingly, when the first mode includes the three modes mentioned above, the transmission mode indication information can indicate each of the three modes respectively. For example, transmission mode indication information F1 corresponds to the control plane transmission mode, transmission mode indication information F2 corresponds to the user plane transmission mode based on the first functional entity, and transmission mode indication information F3 corresponds to the PMF user plane transmission mode. Alternatively, transmission mode indication information KZ corresponds to the control plane transmission mode, transmission mode indication information YH corresponds to the user plane transmission mode based on the first functional entity, and transmission mode indication information PMF corresponds to the PMF user plane transmission mode. The specific form of the transmission mode indication information includes, but is not limited to, the examples above, and is not specifically limited thereto.
[0194] It should be noted that the first communication system may also include a gateway node. The gateway node can be connected to the management node and serve as a communication bridge between the first communication system and other communication systems. The aforementioned transmission mode indication information can be sent by the first functional entity to the first node according to actual conditions, or it can be sent by the management node or gateway node in the first communication system to the first node. Specifically, the management node or gateway node can send pre-configured transmission mode indication information to the first node to instruct the first node to send the first information using the first mode corresponding to the transmission mode indication information.
[0195] The first method can be implemented in several possible ways:
[0196] Implementation Method 1 If the first method is the control plane transmission method, then step S202 may specifically include:
[0197] The first node sends a NAS message to the second functional entity in the second communication system. The NAS message contains the first information.
[0198] Accordingly, the second functional entity receives the NAS message sent by the first node, and then sends the first information back to the first functional entity.
[0199] In this embodiment of the invention, when the first mode is a control plane transmission mode, the first node sends a NAS message to the second functional entity. This NAS message contains first information, which can then be sent from the second functional entity to the first functional entity. For example, the first information can be encapsulated in the NAS message as a message container for transmission.
[0200] Optionally, when the first node sends the first information to the first functional entity via the control plane transmission method, the first functional entity can forward the control policy information through the second functional entity. The control policy information is encapsulated in a NAS message, and the second functional entity sends the NAS message to the first node so that the first node receives the control policy information.
[0201] The following explanation uses the first communication system as an example of a short-range communication system, and the second communication system as an example of a 5G cellular communication system:
[0202] refer to Figure 1a and Figure 1b In this embodiment, the first node is a T node, the first functional entity is an xNF network element, the second functional entity is an AMF network element, and the first method is transmission via the control plane of the xNF network element. (See reference...) Figure 3 , Figure 3 This is a schematic diagram of the transmission protocol stack for a control plane transmission method provided in an embodiment of the present invention; the T node, G node, gateway node TNGF and AMF network elements communicate according to... Figure 3 The protocol stack shown performs data transmission. The first information of node T includes node status information of node T (i.e., the status information of the first node) and / or link status information (i.e., the status information of the first link; in this embodiment, the status information of the first link is the link status between node T and node G, and / or the link status between node T and xNF network element). The first information of node T is encapsulated in a NAS message in the form of a message container and transmitted.
[0203] refer to Figure 1a , Figure 4 , Figure 4 This is a flowchart illustrating the specific interaction process of a communication method provided in this embodiment of the invention. Taking the simultaneous transmission of node status information and link status information of node T as an example, the interaction process between node T and the xNF network element is as follows:
[0204] Step 1: Utilizing node T Figure 3 The transmission protocol stack encapsulates node status information and link status information in the form of message containers in NAS messages and sends them to the AMF network element, which then forwards them to the SMF network element.
[0205] Step 2: The SMF network element sends a request message to the xNF network element. This request message contains the node status information and link status information of the T node.
[0206] Step 3: Based on the status information in Step 2, the xNF network element makes configuration and management decisions to determine the first control policy information for node T. The xNF network element generates the first control policy information based on the node status information and link status information of node T. This first control policy information includes one or more of the following: node status update information (e.g., node hardware version update information, node software version update information, etc.), QoS adjustment requests, node status reporting policies, and link status detection policies. The xNF network element sends the above first control policy information to the SMF network element in the form of a response message.
[0207] Step 4: When the first control policy information includes a QoS adjustment request, the SMF network element responds to the xNF network element's QoS adjustment request by adjusting the QoS policy to generate the QoS policy (i.e., QoS policy configuration information) for node T. The SMF network element then sends the node status update information, node T's QoS policy, node status reporting policy, and link status detection policy to the AMF network element in the form of a response message (specifically, a message container). The AMF network element then sends a NAS response message (i.e., the second control policy information, including one or more of the following: node status update information, QoS policy configuration information, node status reporting policy, and link status detection policy) to node T, enabling node T to maintain and report node status information and detect and report link status based on the received NAS response message. It should be noted that when the first control policy information does not include a QoS adjustment request, after receiving the first control policy information, the SMF network element sends the first control policy information to node T through the AMF network element, enabling node T to maintain and report node status information and detect and report link status based on the received first control policy information.
[0208] use Figure 4 The interaction process, based on node status information, link status information, and the control plane functions of xNF network elements, enables the 5G core network to manage terminal nodes of short-range communication systems, which can effectively improve resource utilization and enhance the integration effect of 5G cellular communication networks and short-range communication systems.
[0209] Implementation Method 2 The first method is the user plane transmission method based on the first functional entity; then step S202 specifically includes:
[0210] S2021. The first node establishes an IP connection with the first functional entity based on the network identification information of the first functional entity.
[0211] Specifically, the first node establishes an IP connection with the first functional entity based on the network identification information of the first functional entity, wherein the network identification information of the first functional entity can be the IP address and port number of the first functional entity.
[0212] S2022. The first node sends the first information to the first functional entity via IP connection.
[0213] Accordingly, the first functional entity receives the first information from the first node based on the aforementioned IP connection.
[0214] Specifically, the first node sends first information to the first functional entity via an IP connection based on a user plane data transmission protocol. In this embodiment of the invention, when the first node sends the first information to the first functional entity via the established IP connection, it can encapsulate the first information using a user plane data transmission protocol to enable the first information to be transmitted through the user plane. The user plane data transmission protocol includes, but is not limited to, the TR-069 transmission protocol.
[0215] Optionally, when the first node sends the first information to the first functional entity through the user plane transmission method based on the first functional entity, the first functional entity can issue control policy information based on the user plane data transmission protocol. That is, the first functional entity sends the control policy information to the first node based on the aforementioned IP connection, so that the first node receives the control policy information.
[0216] Optionally, when the first node sends the first information to the first functional entity through the user plane transmission method based on the first functional entity, the first functional entity can also forward the control policy information through the second functional entity in the second communication system so that the first node can receive the control policy information.
[0217] In some possible implementations, the communication method in this embodiment of the invention further includes:
[0218] The first node sends a first request to the second functional entity in the second communication system. The first request is used to request the network identification information of the first functional entity.
[0219] Accordingly, the second functional entity receives the first request from the first node.
[0220] The first node receives the network identification information of the first functional entity from the second functional entity.
[0221] Accordingly, the second functional entity responds to the first request by sending the network identification information of the first functional entity to the first node. The second functional entity may obtain the network identification information of the first functional entity in advance, or it may obtain the network identification information of the first functional entity upon receiving the first request. No particular limitation is placed on the method by which the second functional entity obtains the network identification information of the first functional entity.
[0222] In this embodiment of the invention, a first request can be sent to the second functional entity to request the network identification information of the first functional entity. The first request can be a Protocol Data Unit (PDU) session request, etc., and is not particularly limited.
[0223] The following explanation uses the first communication system as an example of a short-range communication system, and the second communication system as an example of a 5G cellular communication system:
[0224] refer to Figure 1a and Figure 1b In this embodiment, the first node is a T node, the first functional entity is an xNF network element, the second functional entity is an AMF network element, and the first mode is user plane transmission via the xNF network element. The first information of the T node includes the node state information of the T node (i.e., the state information of the first node) and / or link state information (i.e., the state information of the first link; in this embodiment, the state information of the first link is the link state between the T node and the G node, and / or the link state between the T node and the xNF network element). (See reference...) Figure 5 , Figure 5 This is a schematic diagram of the transmission protocol stack for a user plane transmission method provided in an embodiment of the present invention; the T node, G node, gateway node TNGF, UPF network element, and xNF network element communicate according to... Figure 5 The protocol stack shown performs data transmission. In this embodiment, node status information and / or link status information are configured for user plane transmission based on the TR-069 transmission protocol.
[0225] refer to Figure 1a , Figure 6 , Figure 6 This is a detailed interaction flowchart of another communication method provided in this embodiment of the invention; taking the simultaneous transmission of node status information and link status information of node T as an example, the interaction process between node T and xNF network element is as follows:
[0226] Step 1: During the establishment of a PDU session with the core network, the T node obtains the network identification information of the xNF network element. The PDU session establishment process can be found in section 4.12.5 of the existing 3GPP 23.502 version 17. Figure 4 .12.5-1 (e.g.) Figure 7As shown, Figure 7 This is a flowchart of the PDU session establishment process in existing technology, the difference being that... Figure 6 The N2PDU session request and PDU session establishment acceptance message have added xNF information, which is the network identification information of the xNF network element (including the IP address and port number of the xNF).
[0227] Specifically, node T transmits NAS signaling with gateway node TNGF based on the GTP-U protocol. Next, node T sends a PDU session establishment request to the AMF network element, which includes the PDU session identifier, SSC mode, session type, etc. The AMF network element obtains the network identification information of the xNF network element based on this PDU session request.
[0228] Next, the AMF network element responds to the PDU session establishment request by sending an N2 PDU session request to the TNGF. This N2 PDU session request includes the QoS policy and associated QFI (QoS flow ID), PDU session identifier, PDU session establishment acceptance message, and xNF information. The xNF information is the network identification information of the xNF network element, namely its IP address and port number. The TNGF then sends a request message to the T node, which includes the PDU session establishment acceptance message (IP address, SSC mode, authorized QoS policy, xNF information, etc.), PDU session identifier, TNGF tunnel: F-TEID, Differentiated Services Code Point (DSCP), and QoS information. The T node then sends a response message to the TNGF, which includes the T node tunnel: F-TEID information. The TNGF then sends an N2 PDU session response message to the AMF network element.
[0229] Step 2: Based on the IP address and port of the xNF network element obtained during the PDU session, establish an IP connection between the T node and the xNF network element through the IP address and port of the xNF network element.
[0230] Step 3: Based on the IP connection established between the T node and the xNF network element, user plane information exchange can be performed. The T node sends node status information and / or link status information to the xNF network element based on this IP connection, where reference... Figure 5 The message forwarding process includes:
[0231] Based on the NWt interface, the T node encapsulates its state information (i.e., node state information and / or link state information) using the TR-069 transmission protocol and sends it to the TNGF.
[0232] The TNGF forwards the information to the UPF network element, and the UPF network element parses the information and forwards the relevant status information to the SMF network element.
[0233] Based on the NxNF service interface, the SMF network element sends relevant status information to the xNF network element. Specifically, the SMF network element can send status information to the xNF network element in the form of request messages or reporting messages, and the xNF network element will reply to the SMF network element with configuration or response messages accordingly.
[0234] Step 4: Based on the status information, the xNF network element generates control policy information and sends it to the T node through the relevant functional modules. Figure 6 The status information response. Its specific message sending process includes:
[0235] Based on the status information in step 3, the xNF network element makes configuration and management decisions. The xNF network element generates control policy information based on the node status information and link status information of node T. This control policy information includes one or more of the following: node status update information (e.g., node hardware version update information, node software version update information, etc.), QoS policy configuration information, node status reporting policy, and link status detection policy. Specifically, the xNF network element sends a QoS adjustment request to the SMF network element to request QoS adjustment to obtain the QoS policy configuration information of node T. The xNF network element then sends one or more of the control policy information—node status update information, QoS policy configuration information, link status detection policy, and node status reporting policy—to node T via the xNF network element's user plane data transmission protocol, enabling node T to maintain and report node status information and detect and report link status based on the received control policy information.
[0236] use Figure 6 The interactive process shown, based on the node status information and link status information of the T node and the user plane functions of the xNF network element, enables the 5G core network to effectively manage the T nodes of the short-range communication system, effectively improve resource utilization, and enhance the integration effect of the 5G cellular communication network and the short-range communication system.
[0237] It should be noted that, optionally, when the xNF network element forwards control policy information through the AMF network element, it should refer to... Figure 1a The xNF network element sends control policy information to the AMF network element, which then forwards the control policy information to the T node via either the N1 or N2 interface. Alternatively, the AMF network element can send the control policy information to the gateway node TNGF via the N2 interface, and the TNGF will then forward it to the T node. Alternatively, the TNGF can forward the information to the G node, and the G node will then forward it to the T node.
[0238] Implementation Method 3 When the first method is PMF user plane transmission, then step S202 specifically includes:
[0239] The first node sends first information to the PMF unit based on the network identification information of the PMF unit of the third functional entity in the second communication system.
[0240] Accordingly, the PMF unit of the third functional entity receives the first information from the first node.
[0241] In this embodiment of the invention, when the first mode is the PMF user plane transmission mode, first information is sent to the PMF unit according to the network identification information of the PMF unit in the third functional entity, so that the first information can be sent to the first functional entity through the PMF unit. The network identification information of the PMF unit can be the IP address and port number of the PMF unit.
[0242] Optionally, when the first node sends the first information to the first functional entity via the PMF user plane transmission method, the first functional entity can send control policy information to the first node through the PMF unit so that the first node can receive the control policy information.
[0243] Optionally, when the first node sends the first information to the first functional entity via the PMF user plane transmission method, the first functional entity can also forward the control policy information through the second functional entity in the second communication system so that the first node can receive the control policy information.
[0244] Optionally, the first node sends first information to the PMF unit, including:
[0245] The first node sends one or more detection request messages, such as an end-to-end round-trip time (RTT) detection request message or a packet loss rate detection request message, to the PMF unit. The end-to-end RTT detection request message or the packet loss rate detection request message includes the first information.
[0246] Accordingly, the PMF unit receives one or more detection request messages, such as end-to-end round-trip time (RTT) detection request messages or packet loss rate detection request messages.
[0247] In this embodiment of the invention, when sending the first information to the PMF unit, the first information can be carried in the RTT detection request message or the packet loss rate detection request message, and the first information can be sent to the PMF unit. Simply put, based on the detection interaction process and message structure of RTT and packet loss rate, the reporting of the first information can be completed.
[0248] In some possible implementations, the communication method in this embodiment of the invention further includes:
[0249] The first node sends a second request to the second functional entity in the second communication system. The second request is used to request the network identification information of the PMF unit.
[0250] Accordingly, the second functional entity receives the second request from the first node.
[0251] Receive network identification information from the PMF unit of the second functional entity.
[0252] Accordingly, the second functional entity sends the network identification information of the PMF unit to the first node. The second functional entity may obtain the network identification information of the PMF unit in advance, or it may obtain the network identification information of the PMF unit upon receiving the second request. No particular limitation is placed on the method by which the second functional entity obtains the network identification information of the PMF unit.
[0253] In this embodiment of the invention, a second request can be sent to a second functional entity to request the network identification information of the PMF unit. The second request can be a PDU session request or similar request, and is not specifically limited to any particular type.
[0254] The following explanation uses the first communication system as an example of a short-range communication system, and the second communication system as an example of a 5G cellular communication system:
[0255] refer to Figure 1a and Figure 1b In this embodiment, the first node is a T node, the first functional entity is an xNF network element, the second functional entity is an AMF network element, and the third functional entity is a UPF network element. The first mode is a user plane transmission mode based on PMF units. The first information of the T node includes one or more of the following: node state information (i.e., the state information of the first node) or link state information (i.e., the state information of the first link; in this embodiment, the state information of the first link is the link state between the T node and the G node, and / or the link state between the T node and the UPF network element). (See reference...) Figure 8 , Figure 8 This is a schematic diagram of the transmission protocol stack for a PMF user plane transmission method provided in an embodiment of the present invention; the T node, G node, gateway node TNGF and UPF network elements communicate according to... Figure 8 The protocol stack shown performs data transmission. In this embodiment, the PMF unit encapsulates node status information and / or link status information into data packets and delivers them to the PDU Layer module for transmission.
[0256] refer to Figure 1a , Figure 9 , Figure 9This is a detailed interaction flowchart of another communication method provided in this embodiment of the invention; taking the simultaneous transmission of node status information and link status information of node T as an example, the interaction process between node T and xNF network element is as follows:
[0257] Step 1: During the process of establishing a PDU session with the core network, the T node obtains the network identification information of the PMF unit. The PDU session establishment process can be found in section 4.12.5 of the existing 3GPP 23.502 version 17. Figure 4 .12.5-1(reference Figure 7 The difference is in Figure 9 The N2 PDU session request and PDU session establishment acceptance messages have added PMF information, which is the network identification information of the PMF unit (including the IP address and port number of the PMF unit).
[0258] Specifically, node T transmits NAS signaling with gateway node TNGF based on the GTP-U protocol. Next, node T sends a PDU session establishment request to the AMF network element, which includes the PDU session identifier, SSC mode, session type, etc. The AMF network element forwards this PDU session request to the SMF network element, which then obtains the network identification information of the PMF unit in the UPF network element based on the PDU session request. Then, the AMF network element responds to the PDU session establishment request by sending an N2 PDU session request to TNGF. This N2 PDU session request includes the QoS policy and associated QFI (QoS flow ID), PDU session identifier, PDU session establishment acceptance message, and PMF information. TNGF then sends a request message to node T, which includes the PDU session establishment acceptance message (IP address, SSC mode, authorized QoS policy, PMF information, etc.), PDU session identifier, TNGF tunnel: F-TEID, Differentiated Services Code Point (DSCP), and QoS information. Node T then sends a response message to TNGF, which includes Node T tunnel:F-TEID information. TNGF then sends an N2PDU session response message to the AMF network element.
[0259] Step 2: Based on the IP address and port of the PMF unit obtained during the PDU session, the T node sends its first information to the PMF unit. This can be done through an interaction process based on RTT and packet loss rate detection, or through a new message sending process. The PMF unit then forwards the T node's first information to the xNF network element.
[0260] Optionally, the first information of node T (i.e., node status and / or link status information) and control policy information are carried in the RTT-related messages. That is, the first information of node T and control policy information are carried in the RTT messages exchanged according to the PMF protocol process; specifically, the first information of node T is carried in the RTT detection request message, while the control policy information is carried in the RTT response message of the core network.
[0261] Optionally, the packet loss rate detection related messages may include the first information of node T (i.e., node status and / or link status information) and control policy information. Specifically, the packet loss rate interaction messages exchanged according to the PMF protocol process may include the first information of node T and control policy information; more specifically, the first information of node T may be included in the packet loss rate count request message or the PMF packet loss rate reporting request message, and the control policy information may be included in the core network packet loss rate reporting response message.
[0262] Optionally, node T can directly transmit node T's first information (i.e., node status and / or link status information, such as...) Figure 9 The first information (status information transmission) is sent to the PMF unit. Specifically, based on the NWt interface, the T node sends the first information to the TNGF; based on the N3 interface, the TNGF forwards the first information to the PMF unit of the UPF network element. After the PMF unit receives the first information from the T node, based on the N4 interface, the UPF network element sends the first information to the SMF network element; based on the NxNF service interface, the SMF network element sends the first information to the xNF network element, which then makes a decision based on the first information. Based on the first information, the xNF network element generates control policy information and sends it to the T node through relevant functional modules, i.e. Figure 9 The status information response. Its specific message sending process includes:
[0263] The xNF network element sends a QoS adjustment request to the SMF network element to request the SMF network element to perform QoS adjustment in order to obtain the QoS policy configuration information of node T. The xNF network element then forwards one or more of the control policy information, namely node status update information, QoS policy configuration information, link status detection policy, and node status reporting policy, to the PMF unit, which then sends them to node T so that node T can maintain and report node status information and detect and report link status according to the received control policy information.
[0264] use Figure 9 The interactive process shown is based on the node status information, link status information and PMF extended functions of the T node, enabling the 5G core network to manage the T nodes of the short-range communication system, improving the effective utilization of resources and enhancing the integration effect of the 5G cellular communication network and the short-range communication system.
[0265] It should be noted that, optionally, when the xNF network element forwards control policy information through the AMF network element, it should refer to... Figure 1a The xNF network element sends control policy information to the AMF network element, which then forwards the control policy information to the T node via either the N1 or N2 interface. Alternatively, the AMF network element can send the control policy information to the gateway node TNGF via the N2 interface, and the TNGF will then forward it to the T node. Alternatively, the TNGF can forward the information to the G node, and the G node will then forward it to the T node.
[0266] In this embodiment, when no new xNF network element is added to the 5G cellular communication system, the first functional entity can be an SMF network element. In an optional design, it utilizes... Figure 9 The interaction flow shown illustrates that the SMF network element obtains the first information from node T. Based on this first information, the SMF network element generates QoS policy configuration information, which is then encapsulated by the UPF network element. Finally, the UPF network element forwards the encapsulated QoS policy configuration information to node T. Alternatively, the SMF network element may generate the QoS policy configuration information using other methods instead of the first information; this is not specifically limited here.
[0267] It should be noted that, Figure 4 , Figure 6 , Figure 9 In the interactive flow shown, the first node can also be another node in the short-range communication system, such as the G node. The process of the G node reporting its own first information is the same as that of the T node, and will not be described in detail here. The difference is that the link status information of the G node is the link status between the G node and the 5G core network. The link between the G node and the 5G core network can be the link between the G node and the xNF network element, or the link between the G node and the UPF network element.
[0268] refer to Figure 10 , Figure 10 This is a schematic diagram of another first communication system and a second communication system provided in an embodiment of the present invention; Figure 10In this system, the second communication system is a cellular communication system, which includes a base station 1002, a user plane UPF 1005, a core network UPF 1001, and an SMF 1006; while the first communication system can be one or more of the following: a passive RFID communication system (including a passive RFID node 1003), a short-range communication system (including a short-range T node 1008, a short-range G node 1004, and a short-range gateway node 1009), and a high-precision positioning communication system (including a high-precision positioning node 1010 and a positioning station 1011). The passive RFID communication system, the short-range communication system, and the high-precision positioning communication system can share a short-range G node 1004 of the short-range communication system as the edge gateway of the communication system. The short-range T node 1008 uses the aforementioned communication method to report its first information to the newly added xNF network element in the cellular communication system (…). Figure 10 Similarly, the passive RFID node 1003 and the high-precision positioning node 1010 can use a communication method similar to that of the short-range T node 1008 to report information. (Not shown in the image)
[0269] Optionally, to process the information reported by the nodes, since the information passes through the user plane UPF 1005 during the reporting process to the xNF network element, an edge computing platform 1007, a field network digital twin platform 1012, and an office terminal 1013 can be connected to the user plane UPF 1005. This allows the edge computing platform 1007, the field network digital twin platform 1012, and the office terminal 1013 to process the reported information and display the processing results. The edge computing platform 1007 is an open platform that integrates network, computing, storage, and application core capabilities, located close to the object or data source, to provide the nearest-end service. The field network digital twin platform 1012 is a simulation processing platform that integrates multi-disciplinary, multi-physical quantity, multi-scale, and multi-probability data, utilizing physical models, sensor updates, and operational history. It completes mapping in virtual space, thereby reflecting the entire lifecycle of the corresponding physical equipment.
