In the following detailed description of the present application, some specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these details.

In addition, in the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0043] For the solutions described in this specification and the embodiments, if they involve personal information processing, they will all be processed on the premise of having a legal basis (such as obtaining the consent of the personal information subject, or being necessary for performing a contract, etc.), and will only be processed within the specified or agreed scope.

[0044] Figure 1 is a schematic diagram of the communication system according to an embodiment of the present invention. As Figure 1 shown, the communication system of this embodiment includes a mobile terminal 10 and a Bluetooth mesh network 20. Among them, the mobile terminal 10 can be a smart terminal, a tablet computer, and other smart devices (for example, wearable devices), and the type of the mobile terminal 10 is not limited in this embodiment.

[0045] Further, the Bluetooth mesh network 20 includes N nodes 21 - 2N (N > 1). Among them, the N nodes 21 - 2N in the Bluetooth mesh network 20 can be devices with different functions, such as proxy nodes, relay nodes, and gateway nodes that support the Bluetooth Generic Attribute Protocol (a protocol that requires establishing a communication connection for interaction) and the Bluetooth broadcast or extended broadcast protocol. Among them, in the Bluetooth mesh network 20, broadcast packets can be sent through the Bluetooth broadcast or extended broadcast transmission channel between nodes to achieve interaction. The mobile terminal 10 can achieve interaction with the Bluetooth mesh network 20 through a proxy node. The relay node is mainly responsible for message forwarding.

[0046] Further, the mobile terminal 10 and the gateway node in the Bluetooth mesh network 20 can be used as control devices to configure and control the networked nodes, and can also start the configuration process to network the un-networked devices, so that the un-networked devices can join the Bluetooth mesh network 20.

[0047] In this embodiment, the communication network architecture (i.e., the Bluetooth protocol stack) of the mobile terminal 10 is upgraded and updated to encode its communication interface, thereby adding a Bluetooth broadcast / extended broadcast communication interface, and further enabling the mobile terminal 10 to support the Bluetooth Generic Attribute Profile (GATT) and the Bluetooth broadcast / extended broadcast protocol. Thus, the mobile terminal 10 in this embodiment can interact with the Bluetooth mesh network 20 through a GATT connection or through the Bluetooth broadcast / extended broadcast protocol. Among them, GATT requires that a Bluetooth connection be established between devices first. After the Bluetooth connection is successfully established, data can be exchanged between devices through the GATT protocol. Bluetooth broadcast / extended broadcast can broadcast data packets through the Bluetooth broadcast channel without establishing an actual connection. It should be understood that this embodiment does not limit the method of upgrading and updating the communication network architecture of the mobile terminal 10. For example, the firmware upgrade of the mobile terminal 10 can be achieved through the Bluetooth Low Energy Over-the-Air (BLE OTA) method.

[0048] Figure 2 is a schematic diagram of the communication network architecture of the mobile terminal according to an embodiment of the present invention. As Figure 2 shown, in the improved communication network architecture 30 of the mobile terminal 10 in this embodiment, there is a bearer layer 34. The bearer layer 34 is used to define the way of transmitting data.

[0049] In this embodiment, the bearer layer 34 includes a general protocol bearer module 342 and a broadcast bearer module 343. Among them, the general protocol bearer module 342 supports the GATT protocol. It establishes a communication connection with a proxy node in the Bluetooth mesh network 20 to interact with a functional node in the Bluetooth mesh network 20 through the forwarding of the proxy node, so as to control the target functional node or receive the status information reported by the target functional node through the forwarding of the proxy node, etc. The broadcast bearer module 343 supports Bluetooth broadcast and / or Bluetooth extended broadcast. It does not need to establish a connection with the nodes in the Bluetooth mesh network 20 and can achieve data transmission through broadcast packets.

[0050] In this embodiment, since the mobile terminal 10 can implement the data transmission methods corresponding to the GATT protocol and the advertising / extended advertising protocol, when interacting with the Bluetooth mesh network 20, the channel decision module 341 can select one or both of the data transmission methods to perform data transmission to meet the data transmission requirements of corresponding tasks. For example, users may have latency requirements, reliability requirements, and / or power consumption requirements, etc. for different tasks. Since when establishing a connection through the GATT protocol to implement data transmission, a proxy node is required for forwarding, the data transmission latency is relatively large. Therefore, if the transmission requirements of the current task indicate that it meets a predetermined transmission latency, that is, the timeliness requirement of data transmission is relatively high, the advertising bearer module 343 can be selected to implement data interaction with the Bluetooth mesh network 20 through the advertising transmission channel. At the same time, if the transmission requirements of the current task indicate that it meets a predetermined transmission reliability, that is, it is necessary to ensure that data is not lost as much as possible during transmission, a dual-channel (that is, the general protocol transmission channel and the advertising transmission channel) can be used to implement data interaction with the Bluetooth mesh network 20. It should be understood that this embodiment does not limit the type of task transmission requirements, nor does it limit the data transmission method selected to meet the corresponding requirement type. The requirement type and the selected data transmission method can be adapted to each other. For example, when the amount of data to be transmitted in the current task is relatively large, in order to reduce the power consumption of data transmission, one of the two transmission channels can be selected to implement data transmission, etc. This embodiment will not give further examples here.

[0051] Specifically, in the communication network architecture 30 of the mobile terminal 10, the channel decision module 341 of the bearer layer 34 is configured to obtain an initial message packet and make a data transmission channel decision based on the transmission requirements corresponding to the initial message packet, and obtain a decision result. The initial message packet may include the data content to be transmitted and a message identifier. It should be understood that this embodiment does not limit the specific structure of the initial message packet, and its corresponding fields can be set based on the corresponding protocol, and no further examples will be given here.

[0052] Further, in the communication network architecture 30 of the mobile terminal 10, the general protocol bearer module 342 of the bearer layer 34 is configured to encapsulate the initial message packet into a general protocol data packet in response to the decision result of the channel decision module 341 indicating that the general protocol transmission channel needs to be used, and send the general protocol data packet through the general protocol transmission channel. The advertising bearer module 343 of the bearer layer 34 is configured to encapsulate the initial message packet into an advertising data packet in response to the decision result indicating that the advertising transmission channel needs to be used, and send the advertising data packet through the advertising transmission channel.

[0053] Such as Figure 1As shown, taking node 22 as an example of the proxy node, when the Bluetooth function of the mobile terminal 10 is controlled to be turned on, the mobile terminal 10 scans the connection request sent by the proxy node 22 to establish a communication connection between the mobile terminal 10 and the proxy node 22. In another alternative implementation, when the Bluetooth function of the mobile terminal 10 is controlled to be turned on, the mobile terminal 10 sends a connection request so that the proxy node 22 can scan the connection request sent by the mobile terminal 10, thereby establishing a communication connection between the mobile terminal 10 and the proxy node 22. In other alternative implementations, after the Bluetooth function of the mobile terminal 10 in this embodiment is controlled to be turned on and it is determined that a general protocol transmission channel is required based on the transmission requirements of the current data transmission task, a communication connection with the proxy node 22 is established. This embodiment does not limit the timing of establishing the GATT connection, and it can be configured based on the actual application situation.

[0054] Further, after the bearer layer 34 receives the initial message packet sent by the upper-layer application, the channel decision module 341 makes a data transmission channel decision based on the transmission requirements of the current task corresponding to the initial message packet (such as latency requirements, power consumption requirements, reliability requirements, etc.) to determine which transmission channel to select to implement the data transmission task. Taking the transmission requirement of the current task as the reliability requirement as an example in this embodiment, the decision result determined by the channel decision module 341 is to use a dual-channel to transmit the corresponding data to the target node in the Bluetooth mesh network 20. Further, the general protocol bearer module 342 encapsulates the initial message packet into a general protocol data packet and sends the general protocol data packet to the proxy node 22 through the general protocol transmission channel. The broadcast bearer module 343 encapsulates the initial message packet into a broadcast data packet and sends the broadcast data packet through the broadcast transmission channel.

[0055] Further, the communication network architecture 30 of the mobile terminal 10 further includes an access layer (Upper&access layer) 31, a transport layer (Lower layer) 32, a network layer (Networklayer) 33, and a system layer (System layer) 35. Among them, the access layer 31 is used to convert the messages from the corresponding applications into the format specified by the mesh protocol, upload the received messages to the specified applications, and implement corresponding encryption, decryption, authorization, etc. functions. The network layer 33 is mainly used to define the network address type, define the input and output filters, define the encryption and authentication of network messages, etc. The transport layer 32 is used to split the too long transport layer packets into several parts and distribute them to the network layer, and then combine the short network layer packets into a long packet and send it to the transport layer. The system layer 35 includes the underlying software or hardware components that correspondingly support data transmission.

[0056] Further, the Bluetooth mesh network 20 may include one or more proxy nodes. Since the proxy node needs to de-encapsulate the received general protocol data packet (i.e., GATT data packet) and broadcast the mesh data packet obtained after de-encapsulation, the communication network structure of the proxy node also needs to support the GATT protocol and the broadcast / extended broadcast protocol. That is, the bearer layer of the communication network structure of the proxy node also includes the GATT bearer and the broadcast / extended broadcast bearer. Since it does not need to select a data transmission channel, the bearer layer of the communication network structure of the proxy node may not deploy a channel decision module. However, it should be understood that if the proxy node needs to make a channel decision, it may also deploy a similar channel decision module, and this embodiment does not limit this.

[0057] Further, the proxy node is configured to de-encapsulate the received general protocol data packet, obtain the corresponding target data packet, and broadcast the target data packet. The target data packet is a data packet of the mash protocol type. The Bluetooth mesh network 20 includes functional nodes, that is, nodes that perform corresponding functional operations. The functional node is configured to receive and parse the broadcast data packet sent by the mobile terminal 10 and / or the target data packet sent by the proxy node (or other relay nodes), execute the target operation corresponding to the broadcast data packet or the target data packet in response to itself being the target receiver, and perform a deduplication operation on the received broadcast data packet and / or target data packet based on the message identifier obtained by parsing. In response to itself not being the target receiver, broadcast the received broadcast data packet and / or the target data packet.

[0058] Taking the proxy node 22 and the target receiver as the functional node 25 as an example, the mobile terminal 10 sends corresponding data packets through the general protocol transmission channel and the broadcast transmission channel. After receiving the general protocol data packet, the proxy node 22 unpacks the general protocol data packet, obtains the target data packet of the corresponding mesh protocol type, and broadcasts the target data packet. Suppose the functional node 23 receives the broadcast data packet sent by the mobile terminal 10 through the broadcast transmission channel, parses the broadcast data packet, and the functional node 23 determines that it is not the target receiver and broadcasts the received broadcast data packet. Further, suppose the functional node 23 also receives the target data packet sent by the proxy node 22, parses the target data packet, and the functional node 23 determines that it is not the target receiver and broadcasts the received target data packet. It can be seen that the functional node 25 may receive the message packets sent by the mobile terminal 10 through multiple transmission paths. To avoid the functional node 25 repeatedly performing the same operation, corresponding deduplication operations need to be performed. Optionally, after receiving the data packet, the functional node 25 parses the data packet to obtain the message identifier of the data packet, and determines whether the operation corresponding to the data packet with the same message identifier has been performed based on the message identifier of the data packet. If it has been performed, the currently received data packet is discarded to implement the corresponding deduplication operation. It should be understood that this embodiment does not limit the specific operation process of message deduplication, as long as it can achieve message deduplication.

[0059] Further, when the nodes in the Bluetooth mesh network 20 upload data to the mobile terminal 10, to reduce the power consumption of the mobile terminal, data upload can be achieved only through the general protocol channel. Specifically, the proxy node in the Bluetooth mesh network 20 is further configured to, in response to receiving the original upload packet broadcast by the functional node in the Bluetooth mesh network, parse and encapsulate the original upload packet to generate the upload general protocol data packet corresponding to the general protocol transmission channel, and send it to the mobile terminal 10. Further, the general protocol bearer module 342 in the mobile terminal 10 is configured to unpack the received upload data packet, obtain the original upload packet of the mesh protocol type, and send the original upload packet to the corresponding application.

[0060] In other alternative implementation manners, if there are corresponding data transmission reliability requirements, a dual-channel can also be used for data upload, that is, the mobile terminal 10 can receive the upload data of the Bluetooth mesh network 20 through a dual-channel. Further, the general protocol bearer module 342 and the broadcast bearer module 343 in the mobile terminal 10 are configured to unpack the received upload data packets respectively, obtain the original upload packets of the mesh protocol type, and send the original upload packets to the corresponding applications. It should be understood that when the mobile terminal 10 receives data packets through a dual-channel, corresponding deduplication operations also need to be performed, and the specific method is similar to the above message deduplication operation method and will not be elaborated here.

[0061] In the communication system according to an embodiment of the present invention, the bearer layer of the communication network architecture of the mobile terminal includes a general protocol bearer module and a broadcast bearer module. The mobile terminal is configured to make a data transmission channel decision according to the transmission requirements of the initial message packet, and call the channel bearer module and / or the broadcast bearer module according to the decision result to encapsulate the initial message packet into a general protocol data packet and / or a broadcast data packet, and send the general protocol data packet and / or the broadcast data packet by using the corresponding data transmission channel. The Bluetooth mesh network includes multiple nodes, and is configured to receive the general protocol data packet and / or the broadcast data packet through at least one node. This embodiment enables the communication protocol architecture of the mobile terminal to support the general protocol transmission channel and the broadcast transmission channel, and thus the broadcast transmission channel or the dual-channel can be used to transmit data to reduce the data transmission delay. When the transmission reliability requirement is relatively high, the dual-channel can also be used to transmit data to ensure the reliability and stability of data transmission.

[0062] Figure 3 It is a flowchart of the communication method of the mobile terminal according to an embodiment of the present invention. The communication protocol architecture of the mobile terminal according to an embodiment of the present invention supports the general protocol transmission channel and the broadcast transmission channel. As Figure 3 shown, the communication method of the mobile terminal according to an embodiment of the present invention includes the following steps:

[0063] Step S110, obtain an initial message packet. Optionally, the initial message packet in this embodiment is the data required to be sent by the application layer, and it may include the data content and message identifier required to be sent.

[0064] Step S120, make a data transmission channel decision according to the transmission requirements of the initial message packet. Optionally, the transmission requirements include delay requirements, reliability requirements, and / or power consumption requirements.

[0065] Optionally, in this embodiment, in response to the transmission requirements indicating that a predetermined transmission delay is satisfied, the broadcast transmission channel is determined as the target transmission channel, and in response to the transmission requirements indicating that a predetermined transmission reliability is satisfied, the general protocol transmission channel and the broadcast transmission channel are determined as the target transmission channels. It should be understood that the above manner of making the data transmission channel decision is merely exemplary, and this embodiment does not limit the correspondence between the type of transmission requirements and the corresponding decision results, and it can be configured according to the actual application situation.

[0066] Step S130, encapsulate the initial message packet into a general protocol data packet and / or a broadcast data packet according to the decision result.

[0067] Step S140, send the general protocol data packet and / or the broadcast data packet by using the corresponding data transmission channel.

[0068] In an alternative implementation, if the decision result indicates that data is transmitted using a general protocol transmission channel, the initial message packet is encapsulated into a general protocol data packet and sent through the general protocol transmission channel established with the proxy node. In another alternative implementation, if the decision result indicates that data is transmitted using a broadcast transmission channel, the initial message packet is encapsulated into a broadcast data packet and broadcast using the broadcast transmission channel. In yet another alternative implementation, if the decision result indicates that data is transmitted using both a general protocol transmission channel and a broadcast transmission channel, the initial message packet is encapsulated into a general protocol data packet and a broadcast data packet. The general protocol data packet is sent through the general protocol transmission channel established with the proxy node, and the broadcast data packet is broadcast using the broadcast transmission channel.

[0069] Further, when a node in the Bluetooth mesh network uploads data to the mobile terminal, to reduce the power consumption of the mobile terminal, data upload can be implemented only through the general protocol channel. Specifically, the proxy node in the Bluetooth mesh network is further configured to, in response to receiving the original upload packet broadcast by a functional node in the Bluetooth mesh network, parse and encapsulate the original upload packet to generate an upload general protocol data packet corresponding to the general protocol transmission channel, and send it to the mobile terminal. Further, the mobile terminal receives the upload data packet through the general protocol transmission channel, de-encapsulates the received upload data packet to obtain the original upload packet of the mesh protocol type, and sends the original upload packet to the corresponding application.

[0070] In other alternative implementations, if there are corresponding data transmission reliability requirements, dual channels can also be used for data upload, that is, the mobile terminal can receive the upload data of the Bluetooth mesh network using dual channels.

[0071] In the embodiment of the present invention, the mobile terminal obtains the initial message packet, makes a decision on the data transmission channel according to the transmission requirements of the initial message packet, encapsulates the initial message packet into a general protocol data packet and / or a broadcast data packet according to the decision result, and sends the general protocol data packet and / or the broadcast data packet using the corresponding data transmission channel. Thus, this embodiment enables the communication protocol architecture of the mobile terminal to support the general protocol transmission channel and the broadcast transmission channel. Furthermore, the broadcast transmission channel or dual channels can be used to transmit data to reduce the data transmission delay. When the transmission reliability requirement is relatively high, dual channels can also be used to transmit data to ensure the reliability and stability of data transmission.

[0072] Figure 4 is a schematic diagram of the communication process of the communication system according to the embodiment of the present invention. As Figure 4As shown in the figure, after the bearer layer of the communication network architecture of the mobile terminal receives the initial message packet p1 from the target application, it determines that the initial message packet p1 needs to be transmitted via a dual-channel (GATT and broadcast) method based on the transmission requirements of the current task corresponding to the initial message packet p1 (such as latency requirements, reliability requirements, power consumption requirements, etc.). Further, the Generic Attribute Profile (GATT) Bearer encapsulates the initial message packet p1 in the GATT protocol type to generate a GATT data packet p2, and sends the GATT data packet p2 to the proxy node 41 through the general protocol transmission channel established in advance with the proxy node 41. The Broadcast / Extended Broadcast Bearer encapsulates the initial message packet p1 in the broadcast / extended broadcast protocol type to generate a broadcast type data packet p3. It should be understood that if the initial message packet p1 itself is a data packet that can be broadcast transmitted in the Bluetooth mesh network, the Broadcast / Extended Broadcast Bearer does not need to encapsulate it again. After receiving the broadcast type data packet p3 through the broadcast transmission channel, the functional node 42 parses the broadcast type data packet p3, determines that it is not the target node of the broadcast type data packet p3, and further broadcasts the data packet p3. After receiving the broadcast type data packet p3 through the broadcast transmission channel, the target node 44 parses the broadcast type data packet p3, determines that it is the target node of the broadcast type data packet p3, and based on the message identifier of the broadcast type data packet p3, determines that it has not processed a data packet with the same identifier before, and performs corresponding data processing operations on the broadcast type data packet p3.

[0073] Further, after receiving the GATT data packet p2, the proxy node 41 unpackages the GATT data packet p2. If the unpackaged data packet is a data packet that can be broadcast transmitted in the Bluetooth mesh network, the unpackaged data packet is used as the target data packet p4. If the unpackaged data packet is not a data packet that is broadcast transmitted in the Bluetooth mesh network, the unpackaged data packet is encapsulated based on the Bluetooth mesh protocol to obtain the target data packet p4. Further, after obtaining the target data packet p4, the proxy node 41 broadcasts the target data packet p4.

[0074] After receiving the target data packet p4 through the broadcast transmission channel, the functional node 43 parses the target data packet p4, determines that it is not the target node of the target data packet p4, and further broadcasts the target data packet p4. After receiving the target data packet p4 through the broadcast transmission channel, the target node 44 parses the target data packet p4, determines that it is the target node of the target data packet p4, and based on the message identifier of the target data packet p4, determines that it has processed the data packet p3 with the same identifier before, and discards the target data packet p4 to achieve message deduplication and avoid the situation where the target node 44 processes the same data packet repeatedly.

[0075] Further, when the target node 44 needs to report corresponding data to the target application, the target node 44 generates and broadcasts an original uplink packet p1'. After receiving the original uplink packet p1' through the broadcast transmission channel, the functional node 43 parses the original uplink packet p1', determines that it is not the target node of the original uplink packet p1', and further broadcasts the original uplink packet p1'. After receiving the original uplink packet p1' through the broadcast transmission channel, the proxy node 41 parses the original uplink packet p1', determines that the target node of the original uplink packet p1' is the mobile terminal, encapsulates the original uplink packet p1' using the GATT protocol to generate a GATT uplink packet p2', and sends the GATT uplink packet p2' to the bearer layer of the mobile terminal through the GATT connection established in advance with the mobile terminal. The GATT uplink packet p2' is de-encapsulated through the unified protocol bearer to obtain an uplink data packet p3' and upload it to the target application.
