Description

Bluetooth network access method, related device and storage medium

Technical Field

Background

The bluetooth Mesh technology is a many-to-many key technology based on bluetooth, and the Mesh network is also called a multi-hop network, is a dynamic and continuously expandable network architecture, and can realize transmission between devices so as to construct an Internet of things (IOT) through the intellectualization of the devices.

Provision is a process of adding a node to be networked into a Mesh network, and one device must perform Provision operation to communicate with other nodes in the network. At present, when a bluetooth Mesh device leaves a factory, a universal initial network is set, when the initial network is used for communication, a Protocol Data Unit (PDU) needs to be continuously exchanged between a provider and the bluetooth Mesh device, and if each PDU can be normally received, the theoretical time for completing the Provision process is 3000 milliseconds (3 seconds), but in an actual situation, the average time of the Provision process is about 15 seconds. In the prior art, to improve the transmission efficiency of a data packet, after the data packet is added into a broadcast queue, a device to be networked transmits a confirmation frame of a pre-configuration invitation data packet to a network providing device, and a provider judges whether the confirmation frame of a node to be networked is received in a PB ACK timer, so as to determine the receiving condition of the data packet by proper delay and improve the success rate of networking, thereby improving the overall time performance.

However, when a large number of devices to be networked need to be networked simultaneously, the latency mechanism may result in a long network access time, and the Provisioner does not know which nodes need to be networked currently, and a large number of retransmission packets may also increase the burden of the whole Mesh network, and cannot support fast network access of batch devices.

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In the prior art, to improve the transmission efficiency of a data packet, after the data packet is added into a broadcast queue, a device to be networked transmits a confirmation frame of a pre-configuration invitation data packet to a network providing device, and a provider judges whether the confirmation frame of a node to be networked is received in a PB ACK timer, so as to determine the receiving condition of the data packet by proper delay and improve the success rate of networking, thereby improving the overall time performance. However, when a large number of devices to be networked need to be networked simultaneously, the latency mechanism may result in a long network access time, and the Provisioner does not know which nodes need to be networked currently, and a large number of retransmission packets may also increase the burden of the whole Mesh network, and cannot support fast network access of batch devices.

Based on the above situation, the present application provides a bluetooth network access method, a related apparatus, and a storage medium, which can solve the problem that the prior art cannot support the fast network access of batch devices.

Based on the bluetooth network access method, the application firstly provides a bluetooth network access system.

Specifically, please refer to fig. 1, in which fig. 1 is a schematic structural diagram of a bluetooth network access system according to a first embodiment of the present application. As shown in fig. 1, in the present embodiment, the bluetooth network access system 9 includes a network providing apparatus 10 and a plurality of first devices to be accessed 11.

In this embodiment, the network providing apparatus 10 includes one of a mobile phone, a tablet, and a computer.

In this embodiment, the first device to be networked 11 is a Mesh bluetooth device, for example, a wireless sensor, an illumination device, a monitoring device, etc. having a bluetooth Mesh function, which is not limited in this application.

In this embodiment, the first device to be networked 11 is a Mesh bluetooth device within the coverage of the network providing device 10, and the network providing device 10 may receive a beacon broadcast sent by the first device to be networked 11, and the first device to be networked 11 may also directly receive a broadcast sent by the network providing device 10.

The first devices to be networked 11 can communicate with each other and forward their beacon broadcasts to each other, so that the network providing device 10 receives the beacon broadcasts of more devices to be networked as soon as possible within a set time.

Referring to fig. 2, fig. 2 is a signal flow diagram of a first embodiment of the bluetooth networking system in fig. 1.

In this embodiment, the first device to be networked 11 communicates with the network providing device 10 based on an initial network (network), and sends a beacon broadcast having a first field, where the first field is used to indicate that the first device to be networked 11 supports a fast distribution network. After receiving the beacon broadcast having the first field, the network providing device 10 parses the beacon broadcast to identify the first field, and transmits the target Mesh network information by broadcast, so that the first device to be networked 11 in the scanning state receives the network entry invitation having the target Mesh network information. After receiving the target Mesh network information, the first device to be networked 11 sends a first configuration request packet to the network providing device based on the target Mesh network information, where the first configuration request packet includes a first source Mesh short address of the first device to be networked 11. After receiving the first configuration request packet, the network providing device 10 parses the first source Mesh short address from the first configuration request packet, generates a corresponding second field based on a comparison result between the first source Mesh short address and the prerecorded Mesh short address list, and sends the first configuration response packet including the second field to the first to-be-accessed network device 11, so that after the first to-be-accessed network device 11 receives and parses the first configuration response packet, the first Mesh short address capable of accessing the target Mesh network is obtained based on a parsing result of the second field, and the target Mesh network is accessed based on the first Mesh short address.

After the first devices to be networked 11 access the target Mesh network, they become Mesh nodes (Mesh nodes). The plurality of Mesh nodes can communicate with each other through the corresponding first Mesh short address.

The first Mesh short address may be allocated by the network providing device 10, or may be generated by the Mesh node according to a preset rule.

Referring to fig. 3, fig. 3 is a flowchart illustrating a bluetooth network accessing method according to a first embodiment of the present application. As shown in fig. 3, in this embodiment, the main execution body of the method is a network providing device, and the method includes:

s31: the network providing device receives the beacon broadcast sent by at least one first device to be networked.

In this embodiment, the beacon broadcast (undistributed beacon) sent by the first device to be networked includes a uuid (universal Unique identifier) and Mesh access layer data.

The UUID is a universal unique identifier, is an identifier assigned in advance by the SIG organization and used for uniquely identifying the device, and has a 128-bit address.

In the Mesh access layer, the data format is opcode + param (Parameters), opcode is a command defined by both sides of the protocol, and is the most basic unit for php (Hypertext Preprocessor) program execution. And the receiving end can identify the Opcode after receiving the data and process the corresponding function based on the Opcode. Referring to table 1, table 1 shows a data format of the bluetooth Mesh access layer of the present application.

Table 1 data format of bluetooth Mesh access layer of the present application

Field Name	Size(octets)	Notes
			Opcode	1，2，or 3	Operation Code
Parameters	0to 379	Application Parameters

Wherein, Field Name is Field Name, octets is octet or octet, Operation Code is Operation Code, and Application Parameters are Application Parameters.

In this embodiment, the beacon broadcast of the first device to be networked includes a first field, and the first field is used to represent that the first device to be networked supports a fast network distribution. Specifically, the first field is a command word Opcode defined by the network providing device and the first device to be networked at an application protocol layer, and after receiving the beacon broadcast, the network providing device recognizes the command based on the Opcode in the beacon broadcast and processes the corresponding function based on the command.

In a specific implementation scenario, a first field (command word Opcode) is defined as PRIVATE FAST information (PRIVATE FAST configuration information), and the first field indicates that the first device to be networked supports the FAST distribution network function. The first device to be networked sends the beacon broadcast including the first field, so that the network providing device analyzes the command corresponding to the first field after receiving the beacon broadcast.

In other implementation scenarios, the defined first field may also be other operation codes, as long as the operation code can be identified as having a meaning of supporting the fast distribution network capability, which is not limited in this application.

In this embodiment, the network providing device receives the beacon broadcast sent by at least one first device to be networked within the set time, analyzes all the beacon broadcasts received within the set time, obtains each device identification information (Mac) corresponding to all the first devices to be networked, and adds each device identification information into the device identification information list.

In a specific implementation scenario, the set time is 2 s. In other implementation scenarios, the set time may also be 1s, 3s, or longer, which is not limited in this application.

In this embodiment, within a set time, the network providing device may further receive a beacon broadcast sent by a non-first device to be networked, where the non-first device to be networked refers to a Mesh device that does not support a fast distribution network, and the network providing device also adds identification information of these devices into the device identification information list, and stores a fast network access determination result for all devices to be networked in the device identification information list.

Specifically, please refer to table 2, where table 2 is a list of device identification information of the non-networked devices recorded within a set time.

Table 2 list of device id information of non-networked devices recorded within a set time

Mac address of device to be networked	Whether to support a fast distribution network
		00:01:02:03:04:05	1
00:01:02:03:04:06	1
		00:01:02:03:04:07	0
……	……

Wherein, 1 indicates that the network providing device parses the first field from the beacon broadcast of the device to be networked, that is, the device to be networked is the first device to be networked. And 0 indicates that the network providing device does not parse the first field from the beacon broadcast of the device to be networked, that is, the device to be networked is a non-first device to be networked.

After the network providing device judges that the device to be networked is a device without the first field, the network is distributed through a SIG (Bluetooth Special Interest Group, Bluetooth technical alliance) Mesh standard network access process, the interaction process is complicated, the device does not belong to the protection range of the application, and the interaction process is not elaborated herein.

S32: analyzing the beacon broadcast, and responding to the fact that the beacon broadcast comprises a first field after being recognized, sending target Mesh network information to the first device to be networked through broadcasting, so that the first device to be networked sends a first configuration request packet to the network providing device based on the target Mesh network information after receiving the target Mesh network information; the first field is used for representing that the first device to be networked supports the rapid distribution network, and the first configuration request packet comprises a first source Mesh short address of the first device to be networked.

In this embodiment, the network providing device parses the beacon broadcast, and after recognizing that the beacon broadcast includes the first field, can recognize the first device to be networked that has the fast network access capability based on the well-agreed command corresponding to the Opcode, and send the target Mesh network information to the first device to be networked through broadcasting based on the initial network.

In this embodiment, the network providing device sends the target Mesh network information to the first device to be networked through another Opcode with a good protocol.

The target Mesh network information includes a network key (network key), an application key (app key), and an interaction index (iv index) of the target Mesh network.

In a specific embodiment, after the NETWORK providing device recognizes that the first field is PRIVATE _ FAST _ presence _ INFO, all first devices to be networked that have a FAST NETWORK entry function are recognized based on a well-agreed command, and target Mesh NETWORK information is sent to the first devices to be networked through a well-defined NETWORK _ KEY _ INFO (another Opcode), so that the first devices to be networked can request the NETWORK providing device to set new NETWORK parameters based on the target Mesh NETWORK information. Referring to table 3, table 3 shows a message format of the Mesh network information of the network providing device.

Table 3 message format for network providing device to send Mesh network information of destination

Wherein, NETWORK _ KEY _ INFO is a defined NETWORK KEY command word.

The network providing equipment can identify a plurality of first equipment to be networked supporting the rapid distribution network based on the first field by defining the first field supporting the rapid distribution network, so that a complex matching identification process is avoided, and then a distribution network invitation is sent to the first equipment to be networked at the same time by sending a broadcast message once, so that the difficulty of information configuration can be reduced, and the network access process is further simplified.

In this embodiment, after receiving the network distribution invitation, the first device to be networked sends a first configuration request packet for configuring a new network request to the network providing device based on the target Mesh network information, so as to request the network providing device for a Mesh short address capable of accessing the target Mesh network. Specifically, referring to table 4, table 4 shows a message format for the first network to be accessed to send a new network configuration request.

Table 4 message format for sending new network configuration request by first device to be networked

opcode	Parameters
		CONFIG_NEW_NETWORK_REQUEST	XXXXXXXXX

The configuration _ NEW _ NETWORK _ REQUEST is a command word for configuring a NEW NETWORK REQUEST.

In this embodiment, the first configuration request packet includes a first source Mesh short address of the first device to be networked, where the first source Mesh short address is generated by the first device to be networked based on a preset rule.

S33: and receiving a first configuration request packet, analyzing a first source Mesh short address from the first configuration request packet, and generating a corresponding second field based on a comparison result of the first source Mesh short address and a prerecorded Mesh short address list.

In this embodiment, the list of Mesh short addresses pre-recorded by the network providing device includes all Mesh short addresses used for communication of Mesh nodes that have accessed the network. Specifically, some of the Mesh short addresses are allocated by the network providing device, and some Mesh nodes are generated by a preset rule, but do not conflict with each other.

Since the first source Mesh short address is not allocated by the network providing device, the first source Mesh short address may collide with a Mesh address in a Mesh short address list recorded in advance by the network providing device, and the network providing device needs to perform duplicate checking on the first source Mesh short address.

In this embodiment, in response to that the first source Mesh short address is repeated with a certain Mesh short address in the pre-recorded Mesh short address list, a second field indicating rejection and a new Mesh short address accessible to the target Mesh network are generated. .

Specifically, the network providing device takes the first source Mesh short address for duplicate checking, and after address conflict is found, a result field with an identifier of 0 is generated in a message replying to the first device to be networked, where 0 represents reject. Wherein, the result field is the second field.

Further, the network providing device generates a new Mesh short address capable of accessing the target Mesh network, and the new Mesh short address is used as the communication address of the first device to be networked after being networked. Wherein the value range of the new Mesh short address is 0x 0001-0 x7 FFFF.

And the network providing equipment attaches the second field, the new Mesh short address and the equipment identification to the reply message based on the previously recorded equipment identification of the first equipment to be networked so as to send the reply message to the first equipment to be networked. Referring to table 5, table 5 shows a message format for configuring a new network response sent by the network providing device.

Table 5 message format for network providing device to send configuration new network response

Further, the network providing device adds the generated new Mesh short address into the Mesh short address list for subsequent duplicate checking.

Further, the network providing device deletes the device identification information corresponding to the first device to be networked from the device identification information list.

In this embodiment, in response to that the first source Mesh short address is not repeated with any Mesh short address in the pre-recorded Mesh short address list, a second field indicating reception is generated, and the first source Mesh short address is recorded in the Mesh short address list.

Specifically, the network providing device takes a first source Mesh short address for duplicate checking, generates a result field with an identifier of 1 in a message replying to the first device to be networked after finding that the addresses are not conflicted, wherein 1 represents accept, and directly adds the first source Mesh short address to a Mesh short address list to be used as a communication address of the first device to be networked after being networked.

It can be understood that, by performing duplicate checking on the first source Mesh short address provided by the first device to be networked, and when the Mesh short addresses conflict, the network providing device is used to provide the first device to be networked with a new Mesh short address in the response packet, the Mesh nodes in the target Mesh network can smoothly communicate by using the respective Mesh short addresses.

S34: and sending the first configuration response packet comprising the second field to the first to-be-accessed network device, so that after the first to-be-accessed network device receives and analyzes the first configuration response packet, the first to-be-accessed network device obtains the first Mesh short address of the accessible target Mesh network based on the analysis result of the second field, and accesses the target Mesh network based on the first Mesh short address.

In this embodiment, after receiving the first configuration response packet, the first device to be networked parses the first configuration response packet.

Specifically, if the result of the analysis of the second field (result) is 1, it indicates that the first source Mesh short address does not conflict with any Mesh short address in the Mesh short address list recorded in advance by the network providing device, and the first device to be networked may access the first source Mesh short address as the first Mesh short address to the target Mesh network, so as to perform communication through the first source Mesh short address.

If the result of the analysis of the second field (result) is 0, it indicates that the first source Mesh short address conflicts with a certain Mesh short address in a Mesh short address list pre-recorded by the network providing device, the first device to be networked acquires a new Mesh short address redistributed by the network providing device from the response packet, and accesses the new Mesh short address into the target Mesh network as the first Mesh short address to perform communication through the new Mesh short address.

Further, the network providing device determines whether the device identification information list is empty. Responding to the empty equipment identification information list, and ending the distribution network flow; responding to the condition that the equipment identification information is not empty, and judging whether the preset distribution time is exceeded or not; in response to the exceeding of the pre-configured distribution network time, ending the distribution network flow; and responding to the situation that the pre-configured distribution network time is not exceeded, and continuing to receive the beacon broadcast sent by the at least one first device to be networked.
