Description

Technical Field

[0001] This invention relates to the field of data transmission technology, and in particular to an FTU management method and system that combines 5G and ZigBee. Background Technology

[0002] To promote intelligent and efficient management of power distribution in transformer substations and reduce the intensity of traditional operation and maintenance, integrated distribution terminals are often used in smart IoT systems to upload business data to the IoT platform. As edge devices in the smart IoT system, integrated distribution terminals are responsible for information collection from distribution substations (e.g., transformer load status, voltage and current parameters of transmission lines), uploading and receiving data, and edge computing (e.g., processing and analyzing the collected data locally). They can monitor the operating status of distribution substations in real time, providing strong support for fault diagnosis and data display in the distribution network.

[0003] Converged distribution terminals offer high reliability and stability, meeting the demands of complex power environments. They support multiple communication methods, including Ethernet, low-power wireless, and 5G (5th Generation Mobile Networks or 5th Generation Wireless Systems), allowing for flexible adaptation to different network environments and enabling bidirectional data transmission. Converged distribution terminals can be categorized as Distribution Transformer Supervisory Terminal Units (TTUs), Distribution Terminal Units (DTUs), and Feeder Terminal Units (FTUs), among others.

[0004] In existing technologies, the FTU is affected by the Radio Resource Control Inactivity (RRC) characteristic of the operator's 5G base station, leading to frequent release of radio access resources and frequent FTU disconnections, resulting in unstable FTU communication. RRC inactivity is a state of the Radio Resource Control protocol, indicating that the radio resource control connection between the terminal device (i.e., FTU) and the 5G base station is inactive. If the FTU is idle or has not transmitted data for an extended period, the RRC connection will enter an inactive state. In the RRC inactive state, the FTU can receive control signaling from the 5G base station, but data transmission between the FTU and the 5G base station is impossible.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide an FTU management method and system that combines 5G and ZigBee. The purpose is to ensure that the communication link with the 5G base station is not interrupted by multiple FTU devices through a ZigBee ring network by reporting heartbeat messages, thereby improving the stability of FTU communication and solving the problem of unstable FTU communication caused by the frequent release of radio access resources due to the inactivity of FTUs under RRC.

[0007] The present invention adopts the following technical solution:

[0011] The main control device sends a first heartbeat message to the 5G base station corresponding to the ZigBee ring network; wherein, the first heartbeat message carries the connection status information;

[0012] This also includes:

[0013] The main control device obtains the connection status information of the multiple FTU devices through the ZigBee ring network;

[0014] When a faulty FTU device is present among the plurality of FTU devices, the main control device acquires normal connection information; wherein, the faulty FTU device is: an FTU device that cannot connect normally to the 5G base station; the normal connection information is: the connection status information of the FTU device that is normally connected to the 5G base station among the plurality of FTU devices;

[0015] The main control device sends a second heartbeat message to the 5G base station; wherein, the second heartbeat message carries the normal connection information;

[0016] The 5G base station receives the normal connection information and determines the device identifier of the faulty FTU device according to the FTU list corresponding to the ZigBee ring network.

[0017] The 5G base station generates alarm information carrying the device identifier and sends the alarm information to the user plane network element to report the faulty FTU device to the user plane network element.

[0018] Furthermore, it also includes:

[0019] When the 5G base station malfunctions, the 5G base station sends a fault notification message to the access management network element;

[0020] The access management network element receives the fault notification message and uses the ZigBee ring network to notify the master FTU device; wherein, the master FTU device is: the FTU device in the ZigBee ring network whose network role is coordinator;

[0021] The master FTU device determines the nearest neighboring 5G base station to the malfunctioning 5G base station from at least one neighboring 5G base station that can be connected to the plurality of FTU devices, and allocates new communication resources to the plurality of FTU devices through the access management network element so that the determined neighboring 5G base station can establish a connection with the plurality of FTU devices.

[0022] Furthermore, determining the master control device from the plurality of FTU devices includes:

[0023] From the identified multiple FTU devices, the FTU device with the highest signal strength between itself and the 5G base station is selected, and the FTU device with the highest signal strength is identified as the main control device.

[0024] Secondly, the present invention also provides an FTU control device combining 5G and ZigBee, comprising:

[0025] At least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor for performing the FTU control method combining 5G and ZigBee as described in the first aspect.

[0026] Thirdly, the present invention also provides a non-volatile computer storage medium storing computer-executable instructions that are executed by one or more processors to perform the FTU management method combining 5G and ZigBee described in the first aspect.

[0027] Fourthly, a computer program product containing instructions is provided that, when executed on a computer or processor, causes the computer or processor to perform an FTU control method combining 5G and ZigBee as described in the first aspect.

[0029] Unlike existing technologies, the present invention has at least the following beneficial effects:

[0030] This invention utilizes the first heartbeat message to report connection status information to the 5G base station, thereby improving the communication stability of FTU devices. Simultaneously, since connection status information is not alarm information and does not require real-time reporting; and since FTU devices are often located in substations for transformer monitoring, the location of each FTU device remains unchanged for extended periods, as do the 5G base stations that can connect to the FTU devices. Therefore, this invention utilizes a ZigBee ring network to aggregate FTU devices connected to the same 5G base station within a certain area of ​​the substation. Multiple FTU devices jointly apply for 5G slices and reuse communication tunnels, and the main control device collects the connection status information of each FTU device in the ZigBee ring network, uploading this information together to the 5G base station. This significantly reduces the waste of communication resources and avoids each FTU device independently reporting its connection status to the same 5G base station, thus optimizing the overall network bandwidth usage. Furthermore, it solves the problem of unstable FTU communication caused by frequent release of wireless access resources due to the inactivity characteristics of RRC (Remote Radio Control) affecting FTUs.

[0049] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Example 1:

[0051] To solve the above problems, such as Figure 1 As shown, this embodiment of the invention provides an FTU management method combining 5G and ZigBee, including:

[0052] Step 10: Establish a ZigBee ring network, which includes multiple FTU devices; determine the master control device from the multiple FTU devices.

[0053] The primary control device is one of the FTU devices in the ZigBee ring network. The method for determining the primary control device is determined by those skilled in the art based on the specific usage scenario. In one optional embodiment, the FTU device with the highest signal strength to the 5G base station is selected from the plurality of determined FTU devices, and this FTU device with the highest signal strength is determined as the primary control device.

[0054] ZigBee networks are suitable for communication between multiple FTU devices with short transmission ranges and low data transmission rates. ZigBee networks can also facilitate coordinated communication between thousands of low-power wireless sensors using a dedicated radio standard. In one embodiment, a ZigBee network can be established first. By adding multiple routers and terminal device nodes to this ZigBee network and configuring their routing relationships, a ring network structure is formed, resulting in a ZigBee ring network. Each node (i.e., the FTU device) can communicate completely peer-to-peer, and each node can communicate with other nodes within its wireless communication range without requiring forwarding from other FTU devices. Furthermore, all FTU devices in the ZigBee ring network can communicate with the same 5G base station, allowing multiple FTU devices to share a communication tunnel to transmit data to the 5G base station.

[0055] like Figure 2 The diagram illustrates a specific example of a ZigBee ring network. In one embodiment, after successfully connecting to the corresponding 5G base station, the FTU device sends an access message to the monitoring master station to access the 5G core network. The monitoring master station can be understood as a pre-configured server. Before the FTU devices register with the 5G network, each FTU device can use low-speed bandwidth for message transmission through the monitoring master station. It should be noted that... Figure 2 The monitoring master station and transformer are not shown; each feeder line is connected to the corresponding FTU device at one end and to the transformer monitored by the FTU device at the other end.

[0056] In one embodiment, the ZigBee ring network includes: several feeder lines, several FTU devices, ZigBee channels, and General Packet Radio Service (GPRS) channels. Each feeder line is connected to each FTU device in a one-to-one correspondence; the FTU devices are connected end-to-end via ZigBee channels to form a ring topology, and also connected end-to-end via GPRS channels to form a ring topology. In the ZigBee ring network, the FTU devices communicate with each other via either ZigBee channels or GPRS channels. In one embodiment, automatic switching between ZigBee and GPRS channels is possible; specifically, when the communication signal attenuates excessively during transmission, the communication signal automatically transmits through the ZigBee channel; when the communication signal encounters an obstacle during transmission, the communication signal automatically transmits through the GPRS channel. The ZigBee channel is self-organizing, with low complexity, low power consumption, and low cost, while the GPRS channel has low connection costs, high transmission rates, and short access times.

[0057] Step 20: The main control device obtains the connection status information of the multiple FTU devices through the ZigBee ring network; wherein, the connection status information includes: the connection status of each FTU device in the ZigBee ring network with the 5G base station corresponding to the ZigBee ring network.

[0058] Since each FTU device in a ZigBee ring network can communicate by sending and receiving messages through the ZigBee ring network, the master control device can also use the ZigBee ring network to send and receive messages to collect connection status information of each FTU device.

[0059] Step 30: The main control device sends a first heartbeat message to the 5G base station corresponding to the ZigBee ring network; wherein the first heartbeat message carries the connection status information.

[0060] In this embodiment of the invention, the main control device collects the connection status information of each FTU device in the ZigBee ring network, generates a first heartbeat message carrying the connection status information, and reports the first heartbeat message to the 5G base station to ensure that the communication link to the 5G base station is not interrupted.

[0061] For FTU devices that are online for extended periods, this embodiment of the invention uses heartbeat messages to periodically report the connection status of each FTU device to the corresponding 5G base station, thereby ensuring that the communication link between the FTU device and the 5G base station remains uninterrupted.

[0062] This invention utilizes the first heartbeat message to report connection status information to the 5G base station, thereby improving the communication stability of FTU devices. Simultaneously, since connection status information is not alarm information and does not require real-time reporting; and since FTU devices are often located in substations for transformer monitoring, the location of each FTU device remains unchanged for extended periods, as do the 5G base stations that can connect to the FTU devices. Therefore, this invention utilizes a ZigBee ring network to aggregate FTU devices connected to the same 5G base station within a certain area of ​​the substation. Multiple FTU devices jointly apply for 5G slices and reuse communication tunnels, and the main control device collects the connection status information of each FTU device in the ZigBee ring network, uploading this information together to the 5G base station. This significantly reduces the waste of communication resources and avoids each FTU device independently reporting its connection status to the same 5G base station, thus optimizing the overall network bandwidth usage. Furthermore, it solves the problem of unstable FTU communication caused by frequent release of wireless access resources due to the inactivity characteristics of RRC (Remote Radio Control) affecting FTUs.

[0063] Since heartbeat messages can carry parameters such as signal strength and signal direction, and the location of the FTU device does not change for a long time, once the 5G base station establishes a connection with the FTU device, it only needs to continuously send heartbeat messages to notify the 5G base station that the connection between the 5G base station and the FTU device is normal. Then the 5G base station can identify the FTU device based on the initially established connection.

[0064] like Figure 3 As shown, in practical application scenarios, the integrated power wireless private network utilizes the operator's 5G base stations, which share the public network through a dedicated power 5G core network and a User Plane Function (UPF), to transmit power service data to the power company's own bearer network via independently identified and encapsulated 5G slicing channels and dedicated channels. This data is then transmitted to various service systems via fiber optic connections between the power company and the operator's equipment rooms. Specifically, the UPF to 5G core network is carried through a provincial-level Optical Transport Network (OTN), while the 5G base station to UPF network channel is carried through a municipal-level fiber optic network or a provincial-level backbone fiber optic network. The first heartbeat message is then sent based on this power network architecture.

[0065] A specific example of a first heartbeat message is shown in Table 1 below.

[0066] Table 1. Specific examples of the first heartbeat message.

[0067]

[0068] After being encapsulated using the GTP-C protocol, the first heartbeat message can be correctly transmitted on the N2 interface between the session management network element and the radio access network.

[0069] In a 5G network, when a 5G base station fails, the FTU device connected to that 5G base station needs to reconnect, such as... Figure 8 As shown, after step 30, the following steps are also included:

[0070] Step 401: When the 5G base station fails, the 5G base station sends a fault notification message to the access management network element.

[0071] When a 5G base station detects a fault or loses connection with other network functions (such as access management network elements), it sends a fault notification message to the access management network element through the N2 interface, indicating that it is unavailable.

[0072] Step 402: The access management network element receives the fault notification message and uses the ZigBee ring network to notify the master FTU device; wherein, the master FTU device is: the FTU device in the ZigBee ring network whose network role is coordinator.

[0073] After receiving the fault notification message, the access management network element notifies the main FTU device that the 5G base station is unavailable. This is done through internal communication within the ZigBee ring network to notify all FTU devices connected to the 5G base station that the 5G base station is unavailable.

[0074] Step 403: The main FTU device determines the nearest neighboring 5G base station to the malfunctioning 5G base station from at least one neighboring 5G base station that can be connected to the plurality of FTU devices, and allocates new communication resources to the plurality of FTU devices through the access management network element so that the determined neighboring 5G base station can establish a connection with the plurality of FTU devices.

[0075] When an FTU device determines that a 5G base station has failed, it enters an RRC inactive state and begins listening for system information broadcast by neighboring cells (such as signal strength and cell identifier) ​​to locate available nearby 5G base stations. After identifying a nearby 5G base station, the FTU device initiates a connection request to establish a new connection. The nearby 5G base station receives the connection request and sends a connection request message to the access management network element via the N2 interface. The access management network element allocates new communication resources to the FTU device and sends a connection response message to the nearby 5G base station via the N2 interface. The nearby 5G base station establishes a connection with the FTU device according to the instructions of the access management network element and resumes user plane data transmission. Once all FTU devices in the ZigBee ring network have completed their connections with the nearby 5G base station, the network returns to normal.

[0076] When there are FTU devices in the ZigBee ring network that cannot connect to the corresponding 5G base station, such as Figure 9 As shown, it also includes:

[0077] Step 501: The main control device obtains the connection status information of the multiple FTU devices through the ZigBee ring network.

[0078] Step 502: When there is a faulty FTU device among the plurality of FTU devices, the main control device obtains normal connection information; wherein, the faulty FTU device is: an FTU device that cannot connect normally to the 5G base station; the normal connection information is: the connection status information of the FTU device that is normally connected to the 5G base station among the plurality of FTU devices.

[0079] In this context, the 5G base station corresponding to the ZigBee ring network refers to the same 5G base station that can be connected to all FTU devices in the ZigBee ring network when the connection status between the FTU device and the 5G base station is normal.

[0080] The main control device obtains normal connection information through internal communication within the ZigBee ring network. For FTU devices that cannot obtain normal connection information in the ZigBee ring network, they are identified as faulty FTU devices.

[0081] Step 503: The main control device sends a second heartbeat message to the 5G base station; wherein the second heartbeat message carries the normal connection information.

[0082] The main control device only uses normal connection information to generate heartbeat messages to inform the corresponding 5G base station FTU devices that the connection status is normal.

[0083] Step 504: The 5G base station receives the normal connection information and determines the device identifier of the faulty FTU device according to the FTU list corresponding to the ZigBee ring network.

[0084] Since the 5G base station can obtain the device identifiers (i.e., the FTU list) of all FTU devices in the ZigBee ring network, it matches the FTU list with the FTU devices corresponding to the normal connection information in the second heartbeat message; when there is no normal connection information for a certain FTU device in the second heartbeat message, it determines that the FTU device is a faulty FTU device and obtains its device identifier.

[0085] Step 505: The 5G base station generates alarm information carrying the device identifier and sends the alarm information to the user plane network element to report the faulty FTU device to the user plane network element.

[0086] 5G base stations will report alarm information to the user's network elements.

[0087] In this embodiment of the invention, normal connection information is reported uniformly through the ZigBee ring network, avoiding individual reporting of connection status by each FTU device, and further optimizing the overall network bandwidth usage.

[0088] Example 2:

[0089] This embodiment also provides a specific example of step 10. Specifically, the established ZigBee ring network is applied to a distribution area, which includes multiple FTU devices. The process of determining the head FTU device from among the multiple FTU devices to establish the ZigBee ring network includes:

[0090] Step 10: The head FTU device broadcasts a first request message to all FTU devices within the broadcastable area; wherein, the first request message carries a connectable base station identifier, the connectable base station identifier being the identifier of one of the 5G base stations connected to the head FTU device.

[0091] The head FTU device is used to establish a ZigBee network. The method for determining the head FTU device among multiple FTU devices is determined by those skilled in the art based on the specific application scenario. ZigBee networks are suitable for communication between multiple FTU devices with short transmission ranges and low data transmission rates.

[0092] Within the broadcastable area, all FTU devices except the head FTU device can communicate with the head FTU device, that is, all FTU devices within the broadcastable area can receive the first application message sent by the head FTU device. The broadcastable area is determined by those skilled in the art according to the specific use case. In an optional embodiment, the broadcastable area can be: a range centered on the head FTU device, with the distance between the head FTU device and the head FTU device within a certain value.

[0093] Step 20: When the FTU device meets the first joining condition corresponding to the first application message, a first target ZigBee ring network is established between the head FTU device and the FTU device; wherein, the first joining condition is: the FTU device connects to the 5G base station corresponding to the connectable base station identifier.

[0094] When the FTU device establishes a 5G signal connection with the 5G base station, the signal strength of the corresponding 5G signal is within the corresponding effective range.

[0095] After receiving the first application message broadcast, the FTU device analyzes whether the identifier of the 5G base station connected to it is the same as the identifier of the 5G base station in the first application message. Only FTU devices that meet the first joining condition will be added to the first target ZigBee ring network by the first FTU device. Since the purpose of establishing the ZigBee network in this embodiment is to enable multiple FTU devices to share a communication tunnel for monitoring data reporting, in order to reuse the communication tunnel, these multiple FTU devices must be connected to the same 5G base station so that the FTU devices in the ZigBee ring network can subsequently apply for 5G slices from the same 5G base station.

[0096] This embodiment first establishes a ZigBee network. By adding multiple routers and terminal device nodes and configuring their routing relationships, the ZigBee network can form a ring network structure. Each node (i.e., FTU device) can communicate completely peer-to-peer. Each node can communicate with other nodes within its wireless communication range without the need for forwarding by other FTU devices.

[0097] In one embodiment, an FTU device receives a first request message, determines a first joining condition based on the first request message, and when the FTU device meets the first joining condition, the FTU device returns a connection response message to the head FTU device; wherein the connection response message carries the device identifier of the FTU device. Because 5G base stations have a high distribution density, multiple FTU devices often exist within a broadcastable area. For example, there may be 10 FTU devices in a broadcastable area, of which 9 FTU devices can establish 5G signal connections with the same 5G base station, and 1 FTU device can establish a 5G signal connection with another 5G base station. When the connectable base station identifier carried in the first request message is one of the 5G base stations, if any of the 10 FTU devices, after receiving the first request message, determines that it is also connected to that 5G base station, it returns a connection response message to the head FTU device. When the head FTU device receives a connection response message, it indicates that an FTU device exists within the broadcastable area that can share a communication tunnel with it for monitoring data reporting. Therefore, it can form a first target ZigBee ring network with this FTU device. The head FTU device acts as a coordinator, selecting a communication channel and establishing the first initial ZigBee network. The head FTU device receives connection response messages from FTU devices within the broadcastable area in descending order of signal strength. The head FTU device retrieves the device identifier from the connection response message to identify the FTU device and assigns a short network address to it, adding it to the first initial ZigBee network. The FTU device updates its configuration information according to the short network address to facilitate communication within the first target ZigBee ring network. The short network address is a unique identifier for the FTU device in the ZigBee network; the configuration information can be the routing information of the FTU device in the first target ZigBee ring network. The first FTU device receives connection response messages sequentially, assigns a network role and a short network address to the FTU device that sent the connection response message, returns the short network address to the FTU device for confirmation and records it, and thus completes the process of adding the FTU device to the first initial ZigBee network. Subsequently, the FTU device can use the short network address as its own unique identifier and forward data packets in the first target ZigBee ring network according to the configuration information to communicate with other FTU devices in the first target ZigBee ring network.

[0098] Since FTU devices are often installed in substations to monitor transformers and report monitoring data, and the location of each FTU device remains unchanged for a long time, as does the 5G base station that the FTU device can connect to, and the monitoring data that the FTU device needs to report in each reporting cycle does not change frequently, this invention uses a ZigBee network to aggregate FTU devices connected to the same 5G base station within a broadcastable area of ​​the substation. This facilitates subsequent unified application for 5G slices and reuse of communication tunnels, using each ZigBee network as a basic unit. Since multiple FTU devices within the broadcast range are often of the same type and require similar data reporting, their bandwidth usage will not differ significantly. By enabling multiple FTU devices to jointly apply for 5G slices and share communication tunnels for data reporting, for multiple FTU devices within a ZigBee network, while some FTU devices occupy lower bandwidth, others often occupy higher bandwidth. This avoids each FTU device continuously occupying high bandwidth independently, thereby optimizing the overall network bandwidth usage and greatly reducing the waste of communication resources. It also solves the problem that when an FTU device only reports alarm data, its bandwidth usage remains at a high level, resulting in excessively high overall bandwidth usage for each FTU device.

[0099] This embodiment establishes a ZigBee network, which facilitates internal negotiation among multiple FTU devices within the same ZigBee network when they need to apply for 5G slices, establish communication tunnels, and report monitoring data.

[0100] While the primary coordinator establishes the first target ZigBee ring network, there may be FTU devices within the broadcastable area that do not meet the first joining conditions. To enable these FTU devices to optimize bandwidth usage by establishing a ZigBee network, when an FTU device does not meet the first joining conditions, it is designated as the head FTU device to establish a second ZigBee ring network and generate a second request message carrying the identifier of the target 5G base station; the target 5G base station is connected to this FTU device. This FTU device broadcasts the second request message to all FTU devices within the broadcastable area; FTU devices within the broadcastable area that are not yet connected to the first target ZigBee ring network but are connected to the target 5G base station respond to the received second request message and return a corresponding joining request message to this FTU device; this FTU device parses the received joining request message to obtain the FTU devices that can jointly build the second target ZigBee ring network, and after establishing the second initial ZigBee network, it adds these FTU devices to the second initial ZigBee network to build the second target ZigBee ring network. The process of the FTU device building the second target ZigBee ring network is the same as the process of the first FTU device building the first target ZigBee ring network, and will not be described again here.

[0101] After the first target ZigBee ring network is established, when a connection failure occurs between the primary coordinator and the 5G base station, the network role of the head FTU device in the first target ZigBee ring network is determined as the primary coordinator. An FTU device is selected from the first target ZigBee ring network, and its network role is determined as the backup coordinator for the first target ZigBee ring network. When the primary coordinator cannot connect to the corresponding 5G base station, the backup coordinator is switched to a new primary coordinator, and the new primary coordinator creates a new target ZigBee ring network. The process of the new primary coordinator creating a new target ZigBee ring network is the same as the process of the head FTU device establishing the first target ZigBee ring network, and will not be described again here.
