[0002] Existing wireless broadcasting technologies, such as FM broadcasting, satellite broadcasting, and IP broadcasting, generally suffer from limited coverage, low communication efficiency between devices, high costs, and stringent network environment requirements. In wide-area broadcasting, signal attenuation and insufficient coverage negatively impact user experience, especially in edge areas where signal transmission is even more limited. Furthermore, traditional broadcasting systems rely heavily on infrastructure development, resulting in high costs and low communication efficiency between devices, making them prone to signal delays or interruptions. For example, with IP broadcasting, when Ethernet congestion occurs, broadcast signals are difficult to transmit stably, thus affecting audio quality. While satellite and FM signals offer advantages in terms of long-distance transmission, their low bandwidth cannot guarantee high-quality audio transmission. In addition, most existing transmission points are fixed, limiting the flexibility and adaptability of broadcasting systems by restricting the flexibility of the audio source.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0039] To address the problems in existing technologies, this invention proposes a Halow-WiFi-based wireless broadcasting method to achieve efficient transmission of broadcast signals. The Halow-WiFi-based wireless broadcasting method is described below, as shown in Figure 1, and includes, but is not limited to, the following steps:

[0040] Step 110: Obtain the audio to be played and the target IP address of the target device.

[0041] First, the user can select the audio content to be played via a terminal device (such as a mobile phone, tablet, or computer) and specify the target device. The system obtains the audio data through a network interface and retrieves the target IP address of the target device corresponding to the audio to be played. This IP address is usually assigned by a DHCP server in the local area network or obtained through static allocation. This step ensures that the system can accurately send broadcast data to the specified target device.

[0042] Step 120: Generate a Broadcast Selection Protocol based on the target IP address. The Broadcast Selection Protocol includes the target IP address and the local identity identifier.

[0043] After obtaining the target device's IP address, the system generates a broadcast selection protocol based on that IP address. The broadcast selection protocol includes the target IP address and a local identifier (i.e., the sending device's ID information). The local identifier is used to identify the source of data during subsequent communication, ensuring that broadcast data can be correctly routed to the target device. This protocol helps ensure that broadcast data can be correctly delivered and distributed within the Halow-WiFi network.

[0044] Step 130: Package the broadcast selection protocol and the audio to be played to generate broadcast data to be sent.

[0045] After generating the broadcast selection protocol, the system packages the broadcast selection protocol with the audio data to be played. The packaging method can employ common data encapsulation techniques, such as frame structures or data packet structures. The packaged data, called the broadcast data to be sent, contains both audio data and protocol data to ensure correct transmission and parsing.

[0046] Step 140: Send the broadcast data to be sent to the first-layer Halow-wifi site device through the Halow-Wifi access point, so that the first-layer Halow-wifi site device can perform protocol processing.

[0047] After the broadcast data is packaged, the system transmits it to the first-layer Halow-WiFi station devices (STAs) via the Halow-WiFi access point (AP). Halow-WiFi is a low-power wide-area network wireless communication technology characterized by its wide coverage and low power consumption. In this step, the Halow-WiFi access point transmits the broadcast data to the first-layer Halow-WiFi station devices in the network via a wireless channel. These devices are responsible for the initial processing of the received data. This step marks the beginning of the broadcast data entering the Halow-WiFi network.

[0048] Step 150: If a target device exists in the first layer Halow-wifi site device, the broadcast data to be sent is received through the target device to play the audio to be played.

[0049] When a Layer 1 Halow-WiFi station receives broadcast data to be sent, the system processes the data to check if it is the target device. Specifically, the Layer 1 Halow-WiFi station determines whether it is the target device based on the target IP address information in the broadcast data. If the Layer 1 Halow-WiFi station is confirmed to be the target device, it will receive the broadcast data, extract the audio data from the data packet, and then play the audio data through its built-in audio playback device or a connected external playback device.

[0050] As a further optional embodiment, after the step of sending the broadcast data to be sent to the first-layer Halow-wifi site device via the Halow-wifi access point for protocol processing by the first-layer Halow-wifi site device, the method further includes:

[0051] If there is no target device in the first-layer Halow-wifi site device, the broadcast data to be sent is forwarded to the second-layer Halow-wifi site device through the first-layer Halow-wifi site device for protocol processing by the second-layer Halow-wifi site device;

[0052] When a target device is present in the second-layer Halow-wifi site device, the broadcast data to be sent is received through the target device to play the audio to be played.

[0053] In this embodiment, as shown in Figure 2, after the first-layer Halow-WiFi station device (i.e., the first-layer Halow-WiFi STA in the figure) receives broadcast data from the Halow-WiFi access point (i.e., the Halow-WiFi AP in the figure), if it detects that the first-layer Halow-WiFi station device is not the target device or there is no target device in the network, the first-layer Halow-WiFi station device will forward the data to the next-layer Halow-WiFi station device. The second-layer Halow-WiFi station device (i.e., the second-layer Halow-WiFi STA in the figure) will continue to receive and process the broadcast data. This forwarding process can proceed layer by layer until the target device is found or the maximum transmission level is reached.

[0054] When forwarded to a Layer 2 Halow-WiFi site device, the device checks if its network contains the target device based on the target IP address information contained in the broadcast selection protocol. If the target device is detected, it receives the broadcast data, unpacks it, extracts the audio data, and then begins playing the audio. Through this recursive forwarding mechanism, the system ensures that even if the target device is not in the Layer 1 site device, it can still be found and played through the next layer network node.

[0055] Layer 1 Halow-WiFi site devices: Located in the direct connection layer of the Halow-WiFi access point (AP). These devices establish a direct wireless communication connection with the AP, typically have higher priority, and are responsible for receiving and processing data transmitted from the AP.

[0056] Layer 2 Halow-WiFi site devices: These devices do not have a direct wireless connection to the access point (AP) and typically communicate with Layer 1 site devices. These devices rely on the relay function of the Layer 1 site devices to receive data.

[0057] By introducing a recursive forwarding mechanism across multiple layers of Halow-WiFi site devices, this embodiment further enhances system reliability, ensuring that even if the target device is not in the first-layer site device during wireless broadcasting, data can still be forwarded through other network layers, ultimately leading to the successful playback of audio. This hierarchical processing effectively solves the coverage problem of broadcast data in a wide-area network, increasing system availability.

[0058] As a further optional embodiment, after the step of forwarding the broadcast data to be sent to the second-layer Halow-wifi station device via the first-layer Halow-wifi station device for protocol processing by the second-layer Halow-wifi station device, the method further includes:

[0059] If the target device is not present in the second-layer Halow-wifi site device, the broadcast data to be sent will be discarded.

[0060] In this embodiment, as shown in Figure 2, after the broadcast data is forwarded from the first-layer Halow-WiFi site device to the second-layer Halow-WiFi site device and processed by the second-layer device, if the target device is still not detected in the network, the system will no longer forward the broadcast data. At this time, the second-layer site device will directly discard the data packet. Through this data discarding mechanism, the system effectively avoids the continued transmission of useless data in the network, reducing the occupation of network resources and redundant forwarding of broadcasts.

[0061] This mechanism is particularly suitable for larger network environments, avoiding unlimited hierarchical recursive forwarding of broadcast data, preventing increased bandwidth consumption and accumulated transmission delays, while also improving system efficiency.

[0062] As a further optional embodiment, the step of sending the broadcast data to be sent to the first-layer Halow-wifi site device through the Halow-Wifi access point specifically includes:

[0063] Based on the network topology diagram, determine the first-layer Halow-wifi site devices;

[0064] The broadcast data to be sent is transmitted to the first-layer Halow-wifi site device through the Halow-Wifi access point.

[0065] By discarding broadcast data when no target device is found in the second-layer Halow-WiFi site equipment, this embodiment significantly improves the system's efficiency in utilizing network resources and avoids unnecessary data transmission. When the system cannot find the target device within a reasonable network layer, timely discarding of data packets not only reduces network load but also ensures a more efficient and flexible wireless broadcasting process.

[0066] As a further optional embodiment, the network topology map is generated based on the survival packets sent by the first-layer Halow-wifi site devices and the second-layer Halow-wifi site devices.

[0067] Each Halow-WiFi site device (including both Layer 1 and Layer 2 Halow-WiFi site devices) sends survival packets to its surrounding devices at predetermined time intervals. These survival packets serve to update the connection status and location relationships of various devices in the network in real time. By receiving survival packets, the system can automatically generate and update the current network topology map, which records the hierarchical relationships and connections between Halow-WiFi site devices.

[0068] During the process of generating the network topology map, the Halow-WiFi site device follows these steps:

[0069] Survival packet transmission: Layer 1 and Layer 2 Halow-WiFi site devices transmit survival packets at preset time intervals. The survival packet contains the device's unique identifier and current network status information.

[0070] Survival packet reception and topology map update: After receiving a survival packet, neighboring devices will update the stored network topology map based on the current network hierarchy and device location. Changes in the network status of each device (such as device disconnection or movement) can be reflected in the network topology map in real time through survival packets.

[0071] Dynamic maintenance of the network topology: When a topology change occurs in the network (e.g., some devices go offline or new devices join), the Halow-WiFi site devices will detect the change through liveness packets and immediately update their stored network topology map. This process can be passed down level by level throughout the broadcast network, eventually updating the Halow-WiFi access points (APs) to ensure that the topology of the entire broadcast network is up-to-date.

[0072] By generating and maintaining a network topology map based on survival packets, this embodiment ensures the dynamic adaptability of the Halow-WiFi wireless broadcasting system. Each site device, through sending and receiving survival packets, can automatically sense and update its connection status within the network, generating an accurate network topology map in real time. This topology map provides a reference for the effective transmission of broadcast data, enabling the system to optimize data transmission based on actual network conditions, thus improving the reliability and flexibility of the entire broadcast network.

[0073] As a further optional embodiment, the survival packet is sent by the first-layer Halow-wifi site device and the second-layer Halow-wifi site device at preset intervals.

[0074] In this embodiment, in order to ensure the dynamism and real-time performance of the entire network, the site devices in the Halow-WiFi system actively send liveness packets at regular intervals to ensure real-time updates of network topology information.

[0075] The specific implementation method is as follows:

[0076] Survival packet transmission mechanism: Layer 1 and Layer 2 Halow-WiFi site devices actively transmit survival packets at predetermined time intervals (e.g., every 10 or 30 seconds). These survival packets contain the site device's unique identifier, connection status, and current layer information. This information allows other devices in the network to identify and record the device's presence and its location within the network topology.

[0077] Setting the preset time interval: The system's preset time interval can be configured according to the needs of the actual application scenario. For scenarios with high real-time requirements, the interval for sending survival packets can be set to a shorter interval (e.g., every 5 seconds), while for a more stable network environment, the interval can be appropriately extended (e.g., every 1 minute). This flexible time interval configuration ensures the adaptability of the system.

[0078] Survival packet delivery and reception: When a Layer 1 or Layer 2 site device sends a survival packet, surrounding devices receive these packets and record them in their respective network status information. By analyzing the periodically received survival packets, devices can detect the presence of neighboring devices and whether they are functioning properly. If a survival packet from a device is not received for a period of time, the system can determine that the device may have gone offline or malfunctioned, and thus perform corresponding network updates and adjustments.

[0079] Network status monitoring and topology map updates: Periodic transmission of liveness packets enables the Halow-WiFi network to continuously monitor network status. When device liveness packet information changes, the network topology map is also updated accordingly to reflect the current network connectivity status and device hierarchy, ensuring accurate transmission of broadcast data.

[0080] As a further optional embodiment, before the step of obtaining the audio to be played and the target IP address of the target device, the method further includes:

[0081] Upon loss of the live packet response, a network change notification packet is generated and sent to the Halow-Wifi access point to enable the Halow-Wifi access point to update the network topology.

[0082] In this embodiment, a network status monitoring mechanism is further introduced. When a site device in the Halow-WiFi network loses a device liveness packet response, the system automatically generates a network change notification packet and updates the network topology map in a timely manner to ensure that the transmission of broadcast data can adapt to changes in the network structure.

[0083] The specific implementation method is as follows:

[0084] Survival packet monitoring: During normal operation, the Halow-WiFi access point continuously listens for survival packets sent from Layer 1 and Layer 2 site devices. If the access point fails to receive a survival packet from a site device within a certain time window, it is considered that the device may have dropped the connection or malfunctioned.

[0085] Network Change Detection: When an access point detects the loss of a liveness packet response from a site device, it immediately triggers a network status change detection mechanism. At this time, the system automatically generates a network change notification packet, recording relevant information about the offline device, including the device's identity, IP address, and network layer.

[0086] Sending Network Change Notification Packets: The access point broadcasts the generated network change notification packets to other devices in the network to inform them of the device's downtime or loss of connection. In this way, all relevant devices can be aware of changes in the network topology in real time, avoiding the need to continue sending broadcast data to devices that have failed.

[0087] Network topology update: Upon receiving a network change notification packet, the access point immediately updates its internal network topology, removing offline devices or adjusting the network structure. This topology update ensures that subsequent broadcast data is transmitted based on the latest network structure, preventing data transmission delays or failures due to device disconnection.

[0088] Improved system stability: This mechanism for handling the loss of live packets significantly enhances the stability and adaptability of the Halow-WiFi system. Even if some devices in the network malfunction or go offline, the system can ensure that broadcast data can be successfully transmitted to other available devices by updating the network topology in real time, maintaining the normal operation of the entire network.
