[0002] With the rapid development of Internet of Things technology, more and more critical devices (such as unmanned aerial vehicles, intelligent vehicles, remote medical devices, etc.) need high-reliability network connections. In order to improve communication reliability, a single physical device is often equipped with multiple heterogeneous network interfaces (such as 4G / 5G, WiFi, Ethernet, and dedicated networks), which simultaneously access the cloud platform through multiple links.

[0003] In the prior art, the target link is generally selected according to the link quality (such as signal strength, throughput, and delay), for example, the existing patent with application number 201310314535.1 discloses an Internet of Things communication device, which specifically determines the target communication link based on link quality by setting multiple communication links, thereby realizing selection of the most suitable communication mode for the Internet of Things communication device and improving the real-time performance and stability when communicating using the Internet of Things communication device. However, this type of solution has many problems, such as: it is easy to cause overloading of high-quality links, other link resources are idle, and it is difficult to achieve optimal allocation of overall network resources; the energy consumption of high-quality links may be higher (such as 5G consumes more power than Wi-Fi); different business operations of physical devices have different communication needs (video requires bandwidth, voice requires low delay, etc.), and it is difficult to meet diversified business needs; and the like.

If the instruction type of the message reported by the physical device is a regular operation setting instruction, then the target routing policy is determined to be the MASTER-main link policy from the intelligent routing decision. If the instruction type of the message reported by the physical device is a query notification instruction, then the target routing policy is determined to be the ALL-broadcast policy from the intelligent routing decision.

[0010] In some embodiments, real-time statistics of the communication message frequency of each communication link include: By atomically manipulating the sliding time window using Lua scripts, the communication message frequency (QPS) of each communication link can be counted in real time. i / T, where N is the number of messages arriving on the i-th communication link within the sliding time window T, and T is the size of the sliding time window.

[0011] In some embodiments, the dynamic calculation of the state weight score for each link, based on the communication message frequency and link type characteristics, includes: Dynamically calculate the state weight score W = QPS*C for each link. i Where QPS is the communication message frequency of the communication link, and C i Let i represent the link type characteristics of the i-th communication link.

The terms "first," "second," and "third" used in this application are merely to distinguish similar objects and do not represent a specific ordering of the objects.

[0022] This application provides a method for fusion of multi-link communication data in a device. Figure 1 This is a flowchart illustrating the steps of a device multi-link communication data fusion method according to an embodiment of this application, as follows: Figure 1As shown, the method includes the following steps: Step S102: Load intelligent routing decisions from persistent storage, wherein the intelligent routing decisions include ACS-private network enforcement policy, MASTER-master link policy and ALL-broadcast policy; Specifically, in step S102, for a terminal system (such as a cloud server) that communicates with physical devices via multiple links, during startup, the terminal system loads the configuration data for intelligent routing decisions from persistent storage (such as a database), caches the routing policy data in a memory mapping table (multilinkServiceMap, multilinkEventMap), and simultaneously starts a timed synchronization task to periodically refresh the policy configuration and the online status of the physical devices. The physical quantities involved are: productKey, which represents the IoT product type of the physical device; method, which represents the instruction type of the business operation involved in the information reported by the physical device; and acs, which represents the specific type of intelligent routing policy, with values ​​of ACS, MASTER, or ALL.

[0023] Specifically, the intelligent routing decision includes the ACS-private network enforcement policy, the MASTER-master link policy, and the ALL-broadcast policy: ACS - Private Network Enforcement Policy is used to restrict the target communication link for communicating with physical devices to only select a private network link with a specific identifier. If the private network link is unavailable, the decision fails and an exception is returned, and no other link is used. It should be noted that if the target routing policy determined in the subsequent step S1081 is the ACS-private network forced policy, then the instruction type of the business operation involved in the communication with the physical device must be a critical control instruction (such as flight control instructions, motor control instructions, critical firmware upgrade instructions, etc.). At this time, the terminal system will forcibly scan and select a private network link with a specific identifier. If the private network link is unavailable, the decision will fail and an exception will be thrown. It will never degrade to use other links, thereby ensuring that critical instructions such as flight control and emergency stop are transmitted in a secure and isolated physical channel.

[0024] MASTER - The main link strategy is used to constrain the target communication link that communicates with the physical device to follow a preset manually specified priority rule. If there is no manually specified priority rule, the link with the highest state weight score is selected from multiple communication links as the target communication link. It should be noted that if the target routing strategy determined in the subsequent step S1081 is the MASTER-main link strategy, then the instruction type of the business operation involved in the communication with the physical device must be a regular operation setting instruction (such as working mode setting instruction, parameter configuration instruction, device restart instruction, photo taking instruction, etc.). The MASTER-main link strategy follows the principle of "manually specified priority, dynamic weight selection". If there is no manual intervention (i.e. there is no manually specified priority rule), the terminal system automatically selects the link with the highest score as the target path from the leaderboard through the state weight score dynamically calculated in real time in step S106, thus realizing adaptive routing and automatic fault switching of regular service calls and attribute setting instructions.

[0025] The ALL broadcast policy is used to restrict the target communication links for communicating with physical devices to all communication links, meaning that messages are sent to physical devices through all communication links.

[0026] It should be noted that if the target routing policy determined in the subsequent step S1081 is the ALL-broadcast policy, then the instruction type of the business operation involved in the communication with the physical device must be a query notification instruction (device status query instruction, power query instruction, heartbeat detection instruction, device wake-up instruction, etc.). The terminal system sends the instructions to the physical device simultaneously through all online links of the device, sacrificing bandwidth to obtain the ultimate reachability of the instructions, ensuring that status query, heartbeat detection, or control notification instructions can be successfully received as long as the device has one connected link.

[0027] Step S104: When there are multiple communication links in the physical device and messages are reported, the communication message frequency of each communication link is counted in real time; the communication links include dedicated network links, WiFi communication links, 4G communication links, 5G communication links, etc.

[0028] Specifically, step S104 involves atomically manipulating the sliding time window using Lua scripts to calculate the real-time communication message frequency (QPS) of each communication link, specifically N. i / T, where N is the number of messages arriving on the i-th communication link within the sliding time window T, and T is the size of the sliding time window. Preferably, a Redis ZSet is used to implement the time window, with a window size of 10 seconds to ensure real-time statistics.

[0029] Step S106: Dynamically calculate the state weight score of each link based on the communication message frequency and link type characteristics; Specifically, step S106 involves dynamically calculating the state weight score W = QPS*C for each link. i Where QPS is the communication message frequency of the communication link, and C iThe link type characteristic of the i-th communication link (e.g., 1.2 for private network, 1.0 for WiFi, and 0.8 for 4G).

[0030] Optionally, for steps S104 and S106, in addition to QPS and link type coefficients in real-time weight calculation, link delay, signal strength, packet loss rate, etc. can be introduced as auxiliary factors to form a more comprehensive weight scoring model.

[0031] Step S108: Based on the instruction type and status weight score of the information reported by the physical device, perform intelligent routing decision to select the target communication link from multiple communication links.

[0032] Step S108 specifically includes the following steps: Step S1081: Determine the target routing strategy from the intelligent routing decision based on the instruction type of the message reported by the physical device; It should be noted that a configurable mapping rule base is used to map the command type of business operation to the intelligent routing policy. Specifically, a table of correspondence between command type and routing policy is maintained in the database. When the platform issues a command, the system will parse the product key and method name in the command, query the pre-configured mapping rule base, and automatically select the corresponding routing policy according to the business characteristics of the command.

[0033] Specifically, step S1081 involves matching the instruction type of the service operation involved in the message reported by the physical device from the intelligent routing decision to determine the target routing strategy: (1) If the instruction type of the message reported by the physical device is a critical control instruction involving the core security of the device, then the target routing policy determined from the intelligent routing decision is the ACS-private network mandatory policy; It should be noted that the command types that match the ACS-private network mandatory policy are mainly those critical control commands that involve the core security of the equipment and could cause significant losses. These commands include flight control commands such as takeoff, landing, and emergency stop commands; safety control commands such as motor unlocking and locking commands; and core configuration commands such as critical firmware upgrades. The failure or leakage of these commands could lead to equipment security risks or complete mission failure. Therefore, they must be transmitted through a private network link to ensure absolute reliability and security of communication.

[0034] (2) If the instruction type of the message reported by the physical device is a regular operation setting instruction, then the target routing policy is determined to be the MASTER-main link policy from the intelligent routing decision. It should be noted that the command types matching the MASTER-main link policy cover the device's regular operation and attribute setting commands. These commands include common service calls such as working mode settings, parameter configuration, device restart, and taking pictures, as well as most default commands without explicitly specified policies. These commands are required to be delivered reliably and efficiently, but are not extremely critical. Through the main link's dynamic optimization mechanism, load balancing and fault self-healing are achieved while ensuring communication reliability.

[0035] (3) If the instruction type of the message reported by the physical device is a query notification instruction, then the target routing policy is determined to be the ALL-broadcast policy from the intelligent routing decision.

[0036] It's important to note that the instruction types matched with the ALL-Broadcast strategy are primarily query and notification instructions that are insensitive to repeated reception and prioritize maximum reachability. These instructions include status acquisition instructions such as device status queries and battery level queries; maintenance instructions such as heartbeat detection and device wake-up; and instructions requiring guaranteed delivery, such as control notifications and global broadcasts. The core objective of these instructions is to maximize the probability of delivery; as long as the device has at least one connected link, successful instruction reception is guaranteed.

[0037] Step S1082: Under the constraints of the target routing policy, select the target communication link from multiple communication links based on the state weight score.

[0038] Through the steps described in this application embodiment, the intelligent routing decision is loaded into the application. By combining the three-layer intelligent routing strategy in the decision with the real-time dynamic link communication message frequency, it can effectively cope with the communication needs of different business operations of physical devices, provide reliable and efficient communication guarantees for IoT devices, and solve the problem of how to ensure the rationality of link selection in multi-link communication scenarios.

[0039] This application provides a specific embodiment of a method for fusion of multi-link communication data in a device. Figure 2 This is a flowchart illustrating a device multi-link communication data fusion method according to an embodiment of this application, as shown below. Figure 2 As shown, the method includes the following steps: Device uplink message processing and weight update. When a device reports a message through any communication link, the following physical process is triggered: Step 1: Message Reception and Parsing. Receive network data packets and parse out the device identifier (deviceId), link identifier (linkId), and timestamp (timestamp).

[0040] Step 2: Link Activity Statistics. Using Lua scripts, atomically manipulate the sliding time window T to execute the weighted score calculation formula W = (N*C) / T, where W is the weighted score (reflecting the overall communication capability of the link, in "quality scores / second"), N is the number of messages arriving within the time window T (reflecting the link's activity level, in "messages"), C is the link type coefficient (reflecting the basic communication quality differences between different network types, dimensionless), and T is the sliding window size (set to 10 seconds to ensure real-time statistics). Then update the global communication link ranking list for physical devices.

[0041] Step 3: Combining the weight scores of the communication links with the pre-configured intelligent routing decisions, determine the primary link (i.e., the target communication link) from all communication links, and determine whether it is a new link. Optionally, the routing strategy is not limited to command type; it can also combine contextual information such as device geographical location, current time, and packet size for more refined routing decisions.

[0042] Step 4: Deduplication of main link messages. Query the main link status and perform deduplication judgment: Is the currently reporting link equal to the main link? If yes, continue subsequent business processing; otherwise, silently discard the message. Optionally, uplink message deduplication is not limited to the "main link" mode. For example, the "first to arrive wins" principle can be adopted, or a unique sequence number can be added to the message and global deduplication can be performed on the server side.

[0043] In addition, status monitoring and system maintenance are required, such as: device status synchronization (including periodically querying the list of all online devices and synchronizing multi-link status information through the device shadow mechanism); link health checks (including automatically detecting and cleaning up failed links during weight calculation and maintaining the data validity of the link leaderboard); event notification and status synchronization (when a change in the main link is detected, a MultiLinkStateEvent event is published, including the device identifier, the new main link identifier, and the change type, to notify other services on the platform to synchronize their status and ensure system consistency).

[0044] Preferably, step 3 is specifically exemplified as follows: Scenario setting: Device drone_001 currently has 3 online links; The real-time status in Redis is as follows: Weight leaderboard: {"drone_001_wifi": 95, "drone_001_4g": 80, "drone_001_acs": 60}; Manual main link: No record; All link online indicators are valid; In addition to Redis, in-memory databases or components such as Etcd and Hazelcast can also be used.

[0045] 1) Execution of ACS-Private Network Forced Policy. Receive command: emergencyStop emergency shutdown command, matched with ACS-Private Network Forced Policy; Link scan: The system traverses all link identifiers of the device, executes a string matching algorithm, and searches for links containing the _acs suffix; Status verification: Checks if the Redis key corresponding to drone_001_acs exists to confirm link activity; Path determination: Locates the private network link drone_001_acs and establishes a physical connection to that link.

[0046] 2) Execution of the MASTER-Main Link Policy. Receive command: `setWorkMode` sets the working mode, matching the MASTER-Main Link policy; Priority determination: First, query the manual main link record, finding no manual setting; Weight comparison: Retrieve the weight leaderboard from Redis, execute the sorting algorithm to find the highest-scoring link; Optimal selection: Compare 95 > 80 > 60, determining `drone_001_wifi` as the current main link; Connection establishment: Send the command to establish a connection via the WiFi network.

[0047] 3) Execution of the ALL-Broadcast Policy. Receive command: `getBatteryLevel` queries the battery level and matches it to the ALL-Broadcast policy; Full set retrieval: Reads a list of all online link identifiers for the device from Redis; Multiple copying: Copies the same command data multiple times, preparing to send them through different network interfaces; Parallel transmission: Simultaneously establishes connections and sends data to three links: `drone_001_wifi`, `drone_001_4g`, and `drone_001_acs`.

[0048] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
