Description

Connection method and device for wireless communication, electronic equipment and storage medium
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a wireless communication connection method, a wireless communication connection device, electronic equipment and a storage medium.
Background
According to the existing wireless communication protocol, when information interaction is needed, a fixed communication architecture of alternating communication is adopted. Wherein, the information sent by the latter communication time period is the reply to the information received by the former communication time period. Such a communication architecture is also commonly employed when wireless communication devices make wireless communication connections. The operating state of the wireless communication device when performing a communication connection generally includes an idle state, a wireless connection setup state, or a connection state. For example, the wireless communication device may first be in an idle state, and when the wireless communication device attempts to establish a connection, it enters a wireless connection establishment state for connection request, decision, and confirmation. After successful connection, the wireless communication device enters a connection state and performs wireless communication with higher reliability. In the wireless connection establishment state, if any communication time-division information cannot be correctly transmitted, the communication is considered to be failed. If the communication fails, the error correction mechanism that is typically employed is to return to the original state. For example, return to the idle state and wait for the next radio connection trigger event to reenter the radio connection setup state. Or returning to the initial stage in the wireless connection establishment state, and re-executing the whole connection establishment process.
However, the wireless connection method of the alternate communication has the problems of low success rate of wireless connection and long average establishment time of wireless connection, which affects user experience.

The first device as the wireless connection confirmer transmits the confirmation information a plurality of times and directly enters the connection state after the transmission is completed. The second device, being the party to be acknowledged for the wireless connection, may then attempt to receive (or otherwise refer to as a search for) acknowledgement information multiple times and enter a connected state upon receipt of one of them.

Analysis shows that in the process of establishing the wireless communication connection in the prior art, the influence on the establishment of the wireless communication connection after various information transmission errors is different. Wherein the influence brought by the error of the confirmation information is the greatest. For example, one party to the communication sends an acknowledgement while the other party does not receive, the connection fails. In this case, a long time is required for error correction, for example, in bluetooth low energy (Bluetooth Low Energy) communication, both communication parties typically need 6 connection intervals (connection interval), or 300ms and 600ms to find a connection failure and restart the connection.
In the embodiment of the invention, an alternate communication mechanism is adopted in the broadcast information period or the connection information period, and once communication errors occur, both devices can immediately (for example, a search window length, a typical value is 0.2 ms) discover and return to an initial state. And the acknowledgement information is sent for a plurality of times by adopting a one-way multiple communication mechanism in the acknowledgement information period. The broadcast information time period and the connection information time period can be used for quickly correcting errors, and the confirmation information time period can be used for reducing the probability of information transmission errors, so that the success rate of wireless communication connection establishment is improved as a whole, the average establishment time of wireless connection is reduced, and the user experience is effectively improved.

In some embodiments of the present invention, two bluetooth low energy wireless communication devices, illustratively a bluetooth master device and a bluetooth slave device, respectively. The bluetooth master device is a wireless connection initiator, i.e. is used as the second device in the foregoing embodiment. The bluetooth slave device is a wireless connection recipient and a wireless connection confirmer, i.e., serves as the first device in the foregoing embodiment. The communication two sides divide the connection stage into a connection initiation stage, a connection information interaction stage and a connection confirmation stage.
The connection initiation phase contains a plurality of broadcast information periods, each broadcast information period being 312.5 microseconds long, each two broadcast information periods being 12 milliseconds apart. The connection information interaction phase comprises 1 connection information period, which is 312.5 microseconds long. The connection acknowledgement phase contains 3 acknowledgement information periods, each of 312.5 microseconds long.
The bluetooth slave device transmits broadcast information in a broadcast information period of the connection initiation phase. The broadcast information is encapsulated by adopting a low-power consumption Bluetooth extension transmission packet type. The broadcast information contains at least the identity information of the bluetooth slave device, i.e. the bluetooth address of the bluetooth slave device.
After receiving the broadcast information sent by the Bluetooth slave device in the connection initiation stage, the Bluetooth master device decides whether to establish connection with the Bluetooth slave device according to the broadcast information. If the bluetooth master decides not to establish a connection, it remains in the connection initiation phase. If the Bluetooth master device decides to establish connection, the Bluetooth master device enters a connection information interaction stage and sends connection information to the Bluetooth slave device in a connection information period. The connection information is encapsulated by adopting a low-power Bluetooth connection request packet type. The connection information contains the necessary information to establish a wireless connection, such as the bluetooth address of the bluetooth master, connection interval, synchronization code, wireless channel list, etc.

If the bluetooth slave device decides not to establish a connection, it returns to the connection initiation phase. If the Bluetooth slave device decides to establish a connection, it enters a connection confirmation phase and sends confirmation information to the Bluetooth master device at each confirmation information period. The confirmation information is encapsulated by adopting a low-power Bluetooth connection response packet type. The acknowledgement information contains the necessary information to establish the wireless connection, such as the bluetooth address of the bluetooth slave device, etc.
When the bluetooth master device transmits connection information, it enters a connection confirmation phase and attempts to receive confirmation information during a confirmation information period. When the Bluetooth master device successfully receives at least one confirmation message, judges that the Bluetooth slave device receives wireless connection according to the information contained in the confirmation message, enters a connection state, does not attempt to receive the confirmation message any more, and communicates with the Bluetooth slave device according to the information contained in the connection message.
After the Bluetooth slave device completes the transmission of all 3 pieces of acknowledgement information, the Bluetooth slave device enters a connection state and communicates with the Bluetooth master device according to the information contained in the connection information.
