Technical Field

[0001] This application relates to the technical field of wireless communication, and in particular to the method for automatically switching mesh calls and 5G data network circuit calls.

Background Art

[0002] In related technologies, Bluetooth call technology is widely applied in various fields such as the security call field, the in-vehicle off- load call field, and the small-range communication field such as outdoor construction command. The call device constructs an audio network through a mesh mechanism to realize the real-time call function. Within the coverage range of the Bluetooth signal, the transmission of audio data is possible. The advantages of Bluetooth device communication are short-range wireless connection, low power consumption, ease of pairing and setting, miniaturization, and low cost. However, the limitations of the transmission distance, the relatively low data transfer speed, the susceptibility of the connection stability to interference, the compatibility problems between devices, etc. have an impact on the normal communication between devices. When the usage location is blocked by obstacles such as buildings and slopes of various sizes, or due to the signal interference factors in each frequency band, the strength and reception sensitivity of the Bluetooth signal are affected by the usage environment, frequent interruptions occur, which affects the real-time nature of audio data transmission and the continuity and integrity. In the existing mesh audio network, when a node is disconnected, the audio data of other nodes is lost, and the audio is only maintained within each sub-mesh network. The disconnected node cannot receive / send the uplink / downlink audio data of that node, which affects the audio data transmission between that node and all other nodes. As a result, the user experience of the Bluetooth transceiver is impaired, and a continuous communication function cannot be realized. received and transmitted, and it affects the audio data transmission between all other nodes and that node. As a result, the user experience of the Bluetooth transceiver is impaired, and a continuous communication function cannot be realized. I can't. On the other hand, data network communications offer wide coverage, high-speed data transfer, and support for a variety of devices. It has advantages such as service support and the ability to enable remote communication. Bluetooth is also short-range. Bluetooth mesh network offers superior data network efficiency in communication. A scenario logic model has emerged in which work and data networks complement each other, and data Ket loss can be reduced. [Overview of the project]

[0003] To overcome problems in related technologies, this application applies to mesh communication and 5G data networks. Provides an automatic call switching method. Bluetooth data communication and data network By using them in a fused manner, it effectively overcomes environmental and distance barriers and reduces data packet loss. This allows for the maintenance of real-time, continuous, and complete audio data transmission. This application provides an automatic switching method between mesh calls and 5G data network calls, and the following Includes steps: S1, Bluetooth devices build a mesh network and mesh group The mesh group is formed. The mesh group assigns the device_id to all Bluetooth devices. Assign and record node information. Generate group identifier mesh_group_id, Bluetooth devices within the same mesh group are the same mesh_group_ It has an ID. S2, designate one of the nodes as the master node, and the APP will be accessed via the master node. Create an online group. All Bluetooth devices can connect via the app. Join the online group and report node information to the cloud, and at the same time, on the cloud Nodes are mapped to form a virtual network. Belongs to a group on the cloud. All Bluetooth devices have the same network_group_id. S3, all Bluetooth devices communicate with the app in bidirectional dynamic heart rate data mode. The device status is synchronized in real time with the cloud's mapping node virtual network. This synchronously marks the signal strength and online status of Bluetooth devices; S4, for network communication, mesh mode takes precedence over data communication mode. Online Audio data between nodes will be communicated preferentially in mesh mode; S5, when a Bluetooth device node goes offline, the node device itself Dynamically switches to data network mode via the app, and data network via the cloud. Perform network communication using work mode; S6, if it detects a device node going offline, reports the offline node information, and Upload the current node audio data. After the cloud receives the node audio data, The node processes the audio data and determines whether or not there is cloud data audio. If voice is present, the node voice data and cloud data voice are mixed to create the audio data. Play back. If cloud data audio does not exist, play back the received node audio data directly. To grow; S7, if it detects a device node going offline, multiple mesh networks exist. If you do so, upload the current node audio data. The cloud will then process the node audio data. After receiving the data, the node processes the audio data and determines whether or not there is cloud data audio. If node data audio exists, mix the node audio data and cloud data audio. Play the audio data. If there is no cloud data audio, directly play the received node audio data. In the automatic switching method of the above mesh call and 5G data network call, in S2, all Bluetooth devices belong to the same network_group_id within the virtual network. The same mesh node is assigned to the same mesh_group_id on the cloud, and network_group_id corresponds to the parent hierarchy of mesh_group_id in the cloud. Devices with the same network_group_id communicate in data communication mode via the cloud. In the automatic switching method of the above mesh call and 5G data network call, in S3, after the cloud receives data information and detects a mesh offline device, it notifies the voice to all devices within the same network_group_id. At this time, when all devices send voice information, they need to send mesh audio data packets at the same time and send them to the cloud via APP. The cloud sends this to the offline device. In the automatic switching method of the above mesh call and 5G data network call, when there are offline nodes, if multiple nodes send voice simultaneously, the cloud mixes the voice data and distributes the mixed voice data to the offline devices within the same network_group_id. In the automatic switching method of the above mesh call and 5G data network call, when there are offline nodes, all mesh online devices receive mesh device voice data and cloud voice data simultaneously, and the mesh device voice data is passed through the app. ​​​​​​​​​​​​​​​​ Mix the data and the cloud voice data, and then play them. In the automatic switching method of the above-mentioned mesh call and 5G data network call, when the device becomes offline as a mesh node and the cloud heartbeat data of the node also becomes offline, it is determined that the node is in a detached state. For the detached node, notify the remaining online nodes through the cloud heartbeat data mode. The detached node is determined to be a non-existent node, and there is no need to send voice data to the detached node. For the detached node, notify the remaining online nodes through the cloud heartbeat data mode. The detached node is determined to be a non-existent node, and there is no need to send voice data to the detached node. In the automatic switching method of the above-mentioned mesh call and 5G data network call, when the offline mesh reconnects, the cloud heartbeat data is also automatically reconnected, and the node is determined to be in an online state. When the node reconnects to the mesh or the cloud heartbeat data is reconnected, the cloud determines and notifies whether the device of the node needs to upload voice data. When the node reconnects to the mesh or the cloud heartbeat data is reconnected, the cloud determines and notifies whether the device of the node needs to upload voice data. When the node reconnects to the mesh or the cloud heartbeat data is reconnected, the cloud determines and notifies whether the device of the node needs to upload voice data. In the automatic switching method of the above-mentioned mesh call and 5G data network call, in S4, in S41, when there is no voice of an offline device in the voice data within the same mesh_group_id network, the device only plays the mesh voice data. S42: Among the Mesh online nodes within the same mesh_group_id network, data is transmitted via the Mesh network. When there is an offline device, the node that transmits voice data also transmits voice data via the APP at the same time. S43: Within the same network_group_id, data between different mesh_group_id is transmitted and received in the form of a cloud network. in S41, when there is no voice of an offline device in the voice data within the same mesh_group_id network, the device only plays the mesh voice data. Among the Mesh online nodes within the same mesh_group_id network, data is transmitted via the Mesh network. When there is an offline device, the node that transmits voice data also transmits voice data via the APP at the same time. S43: Within the same network_group_id, data between different mesh_group_id is transmitted and received in the form of a cloud network. twork_group_id, data between different mesh_group_id is transmitted and received in the form of a cloud network. ​​​In the above method of automatically switching between mesh calls and 5G data network calls, the app uses data Nodes are assigned privilege levels, with master nodes having higher privileges than regular nodes. The master node is granted the highest privileges to perform operations on network construction and has access to all nodes in the mesh. It can manage communication data. In the above automatic switching method between mesh calls and 5G data network calls, The code allows for the addition of permission for external device users; listening on a specified device Set the mode to allow only the reception of audio data and prohibit transmission. The technical solution provided in this application includes the following beneficial effects: this mesh communication and 5G data The automatic switching method for network calls monitors the online status of the device in real time. It monitors and automatically sends voice messages to the cloud network when a device / node goes offline. By switching the data transmission, it ensures the normal transmission and reception of voice data at nodes that are unable to communicate, and audio To ensure real-time, continuous, and complete voice data transmission. Meanwhile, online status Voice data continues to be transmitted between nodes via a mesh network, and cloud network By activating the transmission as a backup path in case of node disconnection, voice data transmission It guarantees stability and integrity. Device information and voice data are sent to the cloud via the app. Upload the data, and the cloud will determine the communication status of each node based on the mesh network node's status. By transferring audio data, the normal transmission of audio data is guaranteed even when node communication is down. This achieves the effect of all nodes transmitting audio data online in real time without interruption. do.

[0006] Referring to Figures 1 to 8, this application describes the automation of mesh calls and 5G data network calls. We provide a switching method, including: S1, Bluetooth devices build a mesh network and mesh group The process involves creating a mesh group to connect all Bluetooth devices to the device. Assign an _id and record node information. The group identifier mesh_group_id Created, Bluetooth devices within the same mesh group use the same mesh_gr It has an oup_id. S2, designate one of the nodes as the master node, and access via the master node. Create an online group above. All Bluetooth devices can access the app. Join the online group and report its node information to the cloud. Next, we map the nodes to form a virtual network. All Bluetooth devices Vice has the same network_group_id in the group on the cloud. ru. In S2, the following is also included: S21, all Bluetooth devices are virtual They exist within the same network_group_id within the network. S22, same Mesh nodes are assigned to the same mesh_group_id on the cloud, twork_group_id corresponds to the parent hierarchy of mesh_group_id on the cloud. This applies. Devices with the same network_group_id will receive data via the cloud. Communicate in network mode. In S3, all Bluetooth devices can communicate with the app in bidirectional dynamic heart rate data mode. It communicates and maps the status of Bluetooth devices to the cloud in real time. The virtual network formed by the device synchronizes information and the signal strength of the Bluetooth device. And it marks the online status synchronously. In other words, all devices via Bluetooth It communicates with the app via [method] and continuously displays the current Mesh online status in heartbeat data mode. It reports the status and surrounding Mesh device node status to the cloud. The cloud processes the received data. After processing, the status information of other devices within the same Mesh network is processed using the same heartbeat data model. It delivers data via a code and enables status synchronization between online and offline devices. S3 also includes the following: S31: After the Bluetooth device connects to the app, it will show the current mesh network status. Device status such as information, device information, communication status, and acquired surrounding node status is recorded in Heart. In Beat Data mode, continuously collect data and send it to the cloud, which then processes the device status. It processes basic information. S32, after the cloud receives the data, detects a Mesh offline device, and then... Sends the code information to all devices within the same network_group_id. At this time, Online devices generate Mesh voice data packets along with the voice transmission, and the app It is sent to the cloud via [a specific method]. The cloud then forwards it to the offline device. S33, If there are offline nodes, and multiple nodes transmit audio simultaneously, Loud processes the audio data by mixing it, and the mixed audio data is then shared on the same network. Distribute to offline devices within k_group_id. S34, if offline nodes exist, all Mesh online devices Me The SH device simultaneously receives audio data from the cloud and audio data from the app via Mesh. The device audio data and cloud audio data are mixed and then played back. S35, Device Mesh node goes offline, and the Cloud Heart of that node If the beat data goes offline, the node is determined to be in a disconnected state. Disconnected node Regarding this, it will be transmitted to the remaining online nodes via cloud heartbeat data mode. Distribute the information. A disconnected node is determined to be a non-existent node, and the audio data is sent to the disconnected node. There's no need to believe it. S36, when the offline Mesh reconnects, the cloud heartbeat data is automatically reconnected. The node is then determined to be online. In S4, for network communication, Mesh mode takes precedence over data network mode. Audio data between online nodes will be preferentially transmitted in Mesh mode. In S4, within S41, within the same mesh_group_id network, voice data If the audio from an offline device is not included, the device will only play the Mesh audio data. To occur. S42: Within the same mesh_group_id network, Mesh Data is transmitted between offline nodes via a mesh network. Offline devices exist If present, the node sending the audio data also sends the audio data via the APP. S4 3: Within the same network_group_id, different mesh_group_ Data between IDs is sent and received in a cloud network format, meaning it's transmitted across different subnetworks. If all Mesh nodes present transmit audio data, the operation in step S42 is performed It is necessary. S5, when a Bluetooth device node goes offline, the node device itself Dynamically switches to data network mode via the app, and data network via the cloud. Network communication is performed using work mode. In other words, the device is off Mesh. When it detects a signal, the node device automatically switches to the data network via the app. Network communication is performed via the cloud. S6, when it detects that the device node is offline, the Bluetooth device will turn off It reports in-node information and uploads the current node voice data. The cloud then... After receiving node audio data, the node and audio data are processed, and the presence or absence of cloud data audio is determined. Determine. If cloud data voice exists, then node voice data and cloud data voice. Mix the audio data and play it back. If no audio data exists in the cloud, receive Plays the node audio data directly. S7, if it detects a device node going offline, multiple mesh networks exist. If you do so, upload the current node audio data. The cloud will then process the node audio data. After receiving the data, the node data and audio data are processed to determine whether or not there is cloud data audio. If cloud data voice exists, mix the node voice data and the cloud data voice. Press to play the audio data. If no cloud data audio exists, the received node audio will play. Plays the voice data directly. The app grants permission levels to data nodes, with master nodes having higher authority than regular nodes. It has the highest level of authority and can perform the highest-priority operations in network construction. The terminal node enables data management for all node communications within the mesh network. Specific operations include adding permission settings for external device users and listening mode for specific devices. This includes code specification (allowing only voice data reception and prohibiting transmission).

[0007] Figure 2 shows the voice processing flow diagram for a single node in mesh communication (see Figure 2): Mesh Network Creation / Joining: Devices create or join a mesh network. And, by forming mesh_group_id, a mesh network equipped Bl It will become a Bluetooth-enabled device. At the same time, a device_id will be assigned to the device. By performing node identification, a unique node name and device name are assigned to each device. APP connection: Bluetooth devices that have established a Mesh network can use a dedicated Blu The device connects to the Bluetooth app, enabling data transfer and communication. The data is sent to the app, and the app processes it after receiving it. Heartbeat data transmission: Bluetooth between device and app, and between app and cloud. It communicates in two-way heartbeat data mode. The device and app exchange data and information in real time. Time synchronization is performed, and the app and cloud also communicate, exchange data, and synchronize information. This enables tripartite data synchronization between the device, the application, and the cloud. Create / join a network group on the cloud and create a mesh mirroring group. Join / Become a network. Create or join a network group on the cloud. Forms a _group_id. A virtual network group mapped to the cloud. Create or join a group. Determine the online status of all nodes. After the Bluetooth device network is established, Monitoring of all nodes will begin, and the status of all nodes will be monitored. In this case, determine if multiple Mesh networks exist. If only one node exists, it will directly interact with the Mesh network and generate the audio data of that node. To accomplish. If an offline node is detected, the device will report information about the offline node and emit a sound. Upload the voice data. The cloud receives the node information and voice data and then processes it. At the same time, it checks for the existence of cloud voice data. If cloud voice data exists, The node audio data and the cloud audio data are mixed, and the mixed audio data is... Playback generates audio data for the node. If cloud audio data does not exist, M The esh audio data is played directly to generate the audio data for that node. If all nodes are online and multiple mesh networks exist, the device The current node audio data needs to be uploaded to the cloud. After receiving the node information and node voice data, the node information and node voice data are processed simultaneously. The system determines whether or not cloud audio data exists. If cloud audio data exists, the relevant No The system mixes the audio data and the cloud audio data, and then plays back the mixed audio data. If cloud audio data does not exist, the Mesh audio data will be played directly, and the corresponding noise will be played. Generates audio data for "do".

Device state and device information are synchronized. Figure 7 shows the total when some devices are offline in different mesh networks. This shows an example of a device communication method. Bluetooth devices create a mesh network. Once you become or join, your device will be identified, and multiple Bluetooth devices will communicate via messaging. A network is formed. As shown in the diagram, device device_1, device d device_3 is a mesh network mesh_grou p_id_1 is formed, and devices device_4 and device device_5 are mesh Forms the mesh network mesh_group_id_2. All devices within id_1 (device_1, device_2, device_3) When online, they communicate with each other in mesh mode.

Device de within mesh group mesh_group_id_2 If vice_5 goes offline, mesh_group_id_1 and mes h_group_id_2 exists within the same network_group_id_1. Therefore, the device status and device information are synchronized. Figure 8 shows the total data when some devices leave a different mesh network configuration. Examples of how devices communicate. Bluetooth devices create a mesh network. When you join, it identifies your device and multiple Bluetooth devices form a mesh network. The workpiece is formed as shown in the figure, device device_1, device devic e_2, device device_3 is mesh network mesh_group_id _1 is formed, and devices device_4 and device device_5 form a mesh net Create mesh_group_id_2. mesh_group_id_1 All devices within (device_1, device_2, device_3) are online When in this state, they communicate with each other in mesh mode. On the other hand, mesh_group_id Device 4 within _2 is offline, and device 5 is also offline. If this happens, the entire Mesh group mesh_group_id_2 will go offline. Devices device_4 and device_5 communicate with the APP and exchange heartbeat data bidirectionally. Communication is possible in this mode, but heartbeat data between the app and the cloud will be offline. In this case, devices device_4 and device_5 will be in a disconnected state. Figure 9 shows a fully meshed network where all devices are online. This indicates a partial communication. Bluetooth devices create or join a mesh network. It then becomes an identification device, and multiple Bluetooth devices connect to a mesh network. Form. As shown in the figure, devices device_1, device_2, devic e_3, device_4, and device_5 are in the mesh group mesh_group Form _id_1. Device device_1 is the master node, device devi ce_4 is the listening node, and device_5 is the excluded node. device_1, device_2, and device_3 are online. In this state, communication is performed in mesh mode. Device device_4 is a listening node. As such, data exchange will not take place, and device_5 will be excluded from data exchange as an excluded node. Do not perform. Device device_1, device device_2, device devic e_3, device_4, and device_5 are bidirectional, just like the APP. It communicates in heartbeat data mode. The APP and the cloud communicate in two-way heartbeat data mode. The data network communicates via a code, and multiple apps participate in the same cloud, but The APP on the removed device_5 cannot communicate with the cloud. This allows for control over communication to unnecessary nodes and reduces unwanted noise during communication. Example: A node is making noise. When voice communication is transmitted, other receiving nodes become unable to interpret important information. This automatic switching method between mesh calls and 5G data network calls is used by the device online. It monitors the status in real time and automatically crashes when a device / node goes offline. Switching voice data transmission to the UD network. This will allow voice data from nodes that are unable to communicate. Maintain normal data transmission and reception, ensuring real-time, continuous, and complete voice data transmission. This guarantees that voice will continue to be available in the mesh network between online nodes. It transmits data and uses cloud network transmission as a backup path in case of node disconnection. By activating it from time to time, it ensures the stability and integrity of voice data transmission. The device information and audio data are uploaded to the cloud, and the cloud operates as a mesh network. By transferring audio data from each node based on the node's communication status, the node communication status is determined. This ensures the normal transmission of audio data in the system, and all nodes can transmit audio data in real time without interruption. Achieves the effect of transmitting data.
