Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically, to a broadband and narrowband converged communication system, method, storage medium, and electronic device. Background Technology

[0002] In recent years, with the rapid development of IoT technology, various low-power wide-area communication (LPWAN) technologies have been widely used in the field of long-distance wireless data transmission. Narrowband wireless communication technologies, represented by LoRa and NB-IoT, have advantages such as low power consumption and wide coverage, making them suitable for low-data-rate data transmission scenarios such as sensor monitoring and smart meter reading. Broadband communication technologies, represented by 4G, 5G, and WiFi, have advantages such as high transmission rates and strong real-time performance, making them more suitable for application scenarios with large data volumes and high real-time requirements, such as remote video surveillance and emergency command.

[0003] To meet the dual demands of long-distance coverage and high-speed data transmission in practical applications, some companies in the industry have attempted to integrate narrowband and broadband communication into a single device. For example, publication number CN206517615U discloses an LTE wireless gateway device supporting LoRa technology. This device includes a motherboard with a processor, connected to an Ethernet interface, a WiFi module, a GPS module, an LTE module, a Bluetooth wireless module, and a LoRa wireless module. This solution integrates the LTE and LoRa modules on the wireless gateway motherboard. The LTE module is used for broadband data transmission and backhaul, while the LoRa module enables low-power narrowband wireless access, thus initially achieving the coordinated use of broadband and narrowband communication. However, this solution mainly focuses on the simple integration of physical hardware and basic data forwarding functions. In practical use, this solution is limited to the physical integration of modules and static data forwarding, lacking a dynamic fusion control strategy based on link status and service requirements. When link quality changes or service requirements change in real time, it cannot adaptively switch links and process data, easily leading to low communication efficiency or link interruption, affecting communication stability and reliability.

[0004] Therefore, there is an urgent need for a data communication system that can dynamically and adaptively perform broadband and narrowband convergence control based on real-time link status and service requirements, in order to solve the core defects in the aforementioned existing technologies. Summary of the Invention

[0005] In view of this, in order to solve the above problems, firstly, the present invention proposes a broadband and narrowband converged communication system, comprising: a broadband communication module for providing a communication link with a high data rate; a narrowband communication module for providing a low-power, long-distance communication link; a converged control module for real-time monitoring of the communication link status and dynamically selecting a primary link based on a comprehensive judgment strategy of service requirements and link status, or simultaneously enabling multi-link collaborative transmission, and automatically triggering a fallback mechanism when the primary link is abnormal; a data processing module for performing fragmentation and protocol encapsulation processing on the transmitted data according to the characteristics of the communication link; a terminal device module for collecting and buffering the data to be transmitted, and transmitting the data through the broadband or narrowband communication module; and a central receiving module for receiving data transmitted through multiple links, sorting and reassembling it according to the link identifier and data fragmentation information, and outputting a unified data stream. Among them, the broadband communication module provides high-speed data transmission when the channel quality is good, the narrowband communication module provides reliable communication in scenarios with poor signal coverage or limited power consumption, the convergence control module makes dynamic decisions and switches according to service requirements and link status, the data processing module ensures that the data is adapted to different link protocol encapsulation and fragmentation adaptation, the terminal equipment module supports the collection and transmission of field data, and the central receiving module integrates the data streams of each link and outputs standard format data, thereby realizing a highly reliable and highly flexible broadband and narrowband converged communication mechanism.

[0006] Furthermore, the broadband communication module adopts 4G, 5G, or WiFi communication protocols, while the narrowband communication module adopts LoRa or NB-IoT communication protocols. The specification of the communication protocol clarifies the system's implementation architecture, facilitates system integration and performance comparison, and helps the solution to be practically implemented and adapted to mainstream communication modules.

[0007] In some embodiments, the fusion control module further includes: a link status monitoring unit, used to collect at least one of the following indicators in real time: RSSI, SNR, packet loss rate, RTT, and available bandwidth of broadband and narrowband links; a fusion strategy algorithm unit, used to select a primary communication link based on link status data and a preset service type rule table, and to perform multi-link coordination or switching control; and a fault fallback unit, used to automatically switch to a backup link and perform retransmission or resumption of unacknowledged data when a communication anomaly occurs on the primary link. The link status monitoring unit plays a role in acquiring key communication quality parameters, the fusion strategy algorithm unit plays a role in intelligent decision-making for link selection and parallel coordination, and the fault fallback unit plays a role in ensuring continuous data availability when the primary link fails, thereby improving service continuity.

[0008] In some implementations, the service type rule table includes service type, target rate threshold, target latency threshold, RSSI threshold, SNR threshold, packet loss rate threshold, action instructions, and priority; the rule table supports local configuration and remote updates. The rule table fields and update mechanism support differentiated processing of various services and flexible policy configuration, enabling the system to have higher application adaptability and maintainability.

[0009] In some implementations, the fusion strategy algorithm unit is equipped with a handover hysteresis region and a jitter suppression time window to avoid frequent switching when the link state fluctuates. The handover hysteresis region and jitter suppression time window serve to prevent instability caused by frequent switching due to minor state fluctuations, thereby improving the stability of the communication process and the user experience.

[0010] In some implementations, the data processing module performs lightweight compression or differential coding on the data before sending it to the narrowband link; the central receiving module performs integrity verification on the data fragments originating from the narrowband link, and reassembles the data after passing the verification. Data compression or differential coding reduces the bandwidth pressure on the narrowband link, while the integrity verification mechanism ensures the data remains correct even after transmission through a weak link, thereby guaranteeing data reliability under narrowband link conditions.

[0011] In some implementations, the terminal device module includes a low-power microcontroller (MCU) and supports a deep sleep mode. In deep sleep mode, a narrowband communication module listens for wake-up commands and activates a wideband communication module for data communication upon receiving the wake-up command. The low-power MCU and sleep mechanism extend the terminal's battery life, while the narrowband listener-wake-up mechanism ensures the timely triggering of critical data tasks, achieving a balance between power consumption and responsiveness during long-cycle communication.

[0012] Secondly, this invention proposes a broadband and narrowband converged communication method, comprising the following steps: Step 1: Monitor the link status indicators of broadband and narrowband links in real time through the converged control module, and obtain the rate and real-time requirements of the current service type; Step 2: Based on the business type rule table and link status indicators, perform dynamic selection of links or multi-link collaborative determination; Step 3: When the primary link fails, automatically switch to the backup link to retransmit or resume unacknowledged data; Step 4: The received data fragments are sorted and reassembled according to the link type identifier and fragment information, outputting a unified data stream. Link status acquisition and service awareness serve as the input foundation for fusion decision-making; dynamic selection and coordination strategies ensure adaptive communication quality; the automatic fallback mechanism enhances anti-interference and fault recovery capabilities; and the data reassembly mechanism ensures compatibility with multi-link data flow, thereby improving the system's stability and throughput in complex environments.

[0013] Thirdly, the present invention provides a computer-readable storage medium storing a computer program, wherein the computer program is configured to execute the steps of the methods described in the embodiments of the present application when running.

[0014] Fourthly, the present invention provides an electronic device including a memory and a processor, wherein the memory stores a computer program and the processor is configured to run the computer program to perform the steps of the methods described in the embodiments of the present application.

[0015] This invention enables the fusion control module to be configured to connect with the terminal device module and the broadband / narrowband communication module, collect link status indicators and service type requirements in real time, and dynamically select the primary communication link or collaboratively enable multi-link transmission based on a preset service rule table. In the event of a primary link failure, the fusion control module can trigger a fault fallback unit to switch to a backup link and achieve data retransmission or continuation. The data processing module segments and encapsulates the transmitted data according to the link type; narrowband data can be lightly compressed or differentially encoded to reduce bandwidth consumption. The central receiving module sorts and reassembles multi-link data according to link identifiers and segmentation information to achieve unified output. The terminal device module supports low-power MCUs and a deep sleep mechanism, and can activate the broadband link to complete efficient data backhaul after receiving a wake-up signal from the narrowband monitoring. Simultaneously, the switching hysteresis zone and jitter suppression mechanism in the fusion strategy can avoid communication jitter caused by frequent switching, and the rule table supports local and remote updates, achieving multi-scenario adaptation. Therefore, the present invention can solve the problems of unintelligent communication link selection, slow fault recovery, high power consumption and low link resource utilization efficiency in related technologies, and achieve the beneficial effects of improving link and system stability and communication energy efficiency.
