Description

Background Art

[0002] With the continuous development of communication technology, currently there are solutions where the in-vehicle device supports multiple mobile phones to connect to different communication protocols of the in-vehicle device simultaneously to meet the usage needs of different users. After a mobile phone is connected to the in-vehicle device, if the mobile phone is out of the range of the in-vehicle device or the Bluetooth of the mobile phone has an abnormality, the communication between the in-vehicle device and the mobile phone will be interrupted and a reconnection is required. However, currently there is no reconnection solution for the case where multiple mobile phones are connected to the in-vehicle device simultaneously, and this problem needs to be solved urgently. Summary of the Invention

[0003] One advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. When a communication connection is interrupted, it will perform a reconnection according to the status of other communication connections, avoiding the disconnection of the communication of other connected devices, providing a reconnection solution for supporting multiple terminals to connect to the in-vehicle device simultaneously, ensuring the normal use of multiple communication connections, and meeting the usage needs of multiple terminals to connect to the in-vehicle device simultaneously.

[0004] Another advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. When a communication connection is interrupted, only the corresponding target communication protocol is reconnected, which can ensure the rapid recovery of the interrupted communication connection and will not disconnect the communication connections of other connected devices.

[0005] Another advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. When a communication connection is interrupted, the target terminal where the interruption occurs is determined for reconnection, which can ensure the rapid recovery of the communication connection of the previously interrupted terminal for normal use.

[0006] Another advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. When a communication connection is interrupted, the historical terminal list is traversed for reconnection, which can ensure a quick connection to an available terminal for rapid recovery of use.

[0007] Another advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. When a terminal with priority connection is set, the terminal with priority connection is used as the first terminal to be tried for connection during the reconnection process, enabling the user to flexibly set the terminal for reconnection and improving convenience.

[0008] Another advantage of the present invention is to provide a wireless communication connection method, an electronic device, and a storage medium. By using a timer to periodically detect the status of establishing a communication connection for reconnection, the waiting time for reconnection can be shortened to achieve efficient and rapid reconnection.

[0009] Another advantage of the present invention lies in providing a wireless communication connection method, an electronic device, and a storage medium. By using the change information of the connection state of the wireless communication physical link, the state of establishing a communication connection can be accurately and quickly determined, improving the processing efficiency.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not deviate from the spirit and scope of the present invention.

[0030] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" cannot be understood as a limitation on the number.

[0031] Referring to Figure 1 As shown, a wireless communication connection method of a preferred embodiment of the present invention includes:

[0032] Step 101: Detect that the first communication connection is interrupted.

[0033] Here, the in-vehicle device supports multiple terminals (such as mobile phones) to connect to different communication protocols of the in-vehicle device at the same time. When detecting that the first communication connection is interrupted, it can quickly respond for reconnection.

[0034] Step 102: Determine the terminal to be connected.

[0035] Here, when detecting that the first communication connection is interrupted, first determine the terminal to be connected for reconnection with it.

[0036] Among them, the embodiments of the present invention support multiple ways to determine the terminal to be connected to adapt to different requirements, which will be introduced in detail later.

[0037] Step 103: Detect the status of other communication connections except the first communication connection.

[0038] Here, after determining the terminal to be connected, it is necessary to detect the status of other communication connections except the disconnected first communication connection, so as to perform reconnection according to the status of other communication connections, so as to avoid interference and interruption of other communication connections during reconnection.

[0039] Step 104: Send a communication connection request to the terminal to be connected according to the status of the other communication connections.

[0040] Here, after detecting the status of other communication connections, reconnection will be performed according to the status of other communication connections, so as to avoid disconnection of the communication of other connected devices, ensure the normal use of multiple communication connections, and meet the usage requirements of multiple terminals (such as mobile phones) connecting to the in-vehicle unit through different communication protocols.

[0041] Step 105: Stop sending the communication connection request when establishing a communication connection with the terminal to be connected.

[0042] Here, when establishing a communication connection with the terminal to be connected, that is, when the reconnection is successful, stop sending the communication connection request to release resources.

[0043] Step 106: Stop sending the communication connection request when the number of times of sending the communication connection request reaches a preset number of times.

[0044] Here, in the embodiments of the present invention, multiple attempts can be made to send a communication connection request during reconnection, but the communication connection request is not sent without limit. Instead, an upper limit on the number of send times is set. When the number of times of sending the communication connection request reaches the preset number of times, stop sending the communication connection request to ensure the reliability of reconnection while avoiding unlimited sending and optimizing the solution.

[0045] Among them, the preset number of times can be set to any value according to requirements. For example, the preset number of times can be 90 times.

[0046] The wireless communication connection method of the embodiments of the present invention will perform reconnection according to the status of other communication connections when a communication connection is interrupted, avoiding disconnection of the communication of other connected devices, providing a reconnection solution that supports multiple terminals to connect to the in-vehicle unit at the same time, ensuring the normal use of multiple communication connections, and meeting the usage requirements of multiple terminals (such as mobile phones) connecting to the in-vehicle unit at the same time.

[0047] As an alternative embodiment, the above step 104 includes:

[0048] Step 1041: When the other communication connection is established, determine the communication protocol occupied by the other communication connection.

[0049] Here, when the first communication connection is disconnected and the other communication connection is established, first determine the communication protocol occupied by the other communication connection to avoid interference with the communication protocol occupied by the other communication connection and ensure connectivity.

[0050] Step 1042: Determine other communication protocols except the occupied communication protocol.

[0051] Here, after determining the communication protocol occupied by the other communication connection, further determine other communication protocols except the occupied communication protocol to send a communication connection request using other communication protocols and avoid interference with the occupied communication protocol.

[0052] Step 1043: Send a communication connection request to the terminal to be connected through the other communication protocol.

[0053] Here, send a communication connection request to the terminal to be connected through other communication protocols except the occupied communication protocol for reconnection, avoiding interference and interruption to other communication connections during reconnection, ensuring the normal use of multiple communication connections, and meeting the usage requirements of multiple terminals (such as mobile phones) connecting to the in-vehicle head unit through different communication protocols simultaneously.

[0054] For example, assume that the in-vehicle head unit supports multiple mobile phones connecting to the in-vehicle head unit through HFP (Hands-Free Profile) and A2DP (Advanced Audio Distribution Profile) simultaneously. When the communication connection corresponding to the A2DP protocol is interrupted and the communication connection corresponding to the HFP protocol is established, determine that the other communication protocol except the HFP protocol is A2DP. Then send a communication connection request to the terminal to be connected through the A2DP protocol to ensure that the communication connection corresponding to the HFP protocol is not interrupted and meet the usage requirements of multiple mobile phones connecting to the in-vehicle head unit through different communication protocols simultaneously. When the communication connection corresponding to the A2DP protocol is interrupted and the communication connection corresponding to the HFP protocol is not established, a communication connection request can be sent to the terminal to be connected through either the HFP or A2DP protocol.

[0055] At this time, when a communication connection is interrupted, perform reconnection through other unoccupied communication protocols to avoid interference and interruption to other communication connections.

[0056] As an optional implementation manner, the above Step 1042 includes:

[0057] Step 10421: Determine the target communication protocol used by the first communication connection.

[0058] Here, when the first communication connection is disconnected and other communication connections are established, the target communication protocol used by the interrupted first communication connection is determined, so as to send a communication connection request using the target communication protocol, avoiding interference with other occupied communication protocols.

[0059] The above step 1043 includes:

[0060] Step 10431: Send a communication connection request to the to-be-connected terminal through the target communication protocol.

[0061] Here, when a communication connection is interrupted, only the corresponding target communication protocol is reconnected, ensuring that the interrupted communication connection can be quickly restored and the communication connections of other connected devices will not be disconnected, ensuring the normal use of multiple communication connections and meeting the usage requirements of multiple terminals (such as mobile phones) connecting to the vehicle head unit through different communication protocols at the same time.

[0062] As mentioned above, the embodiments of the present invention can be adapted to different requirements and support multiple ways to determine the to-be-connected terminal. The following is an introduction.

[0063] Method 1. Optionally, the above step 102 includes:

[0064] Step 1021: Determine the target terminal corresponding to the first communication connection.

[0065] Here, when the first communication connection is disconnected, the target terminal corresponding to the first communication connection is determined to be used as the to-be-connected terminal for reconnection.

[0066] Step 1022: Use the target terminal as the to-be-connected terminal.

[0067] Here, using the target terminal where the interruption occurs as the to-be-connected terminal for reconnection can ensure that the previously interrupted terminal quickly restores the communication connection for normal use.

[0068] For example, assume that mobile phone A and mobile phone B are connected to the vehicle head unit through different communication protocols. When the first communication connection between mobile phone A and the vehicle head unit is disconnected, the target terminal corresponding to the first communication connection, that is, mobile phone A, is determined as the to-be-connected terminal for reconnection, so that mobile phone A can quickly restore the communication connection with the vehicle head unit for normal use.

[0069] Method 2. Optionally, the above step 102 includes:

[0070] Step 1023: Traverse the list of historical terminals that have been connected.

[0071] Here, when the first communication connection is disconnected, according to requirements, the entire list of historical terminals can also be reconnected. First, traverse the list of historical terminals to find connectable terminals.

[0072] Among them, the historical terminal list refers to a list that records all the terminals that have been connected. Whenever a communication connection occurs, the connected terminal can be recorded in this historical terminal list.

[0073] Among them, in order to maintain the accuracy of the historical terminal list, the terminals that have not been connected for a long time (such as exceeding a preset time) in the historical terminal list can also be cleared regularly, or a clearing operation of the user is received, and the corresponding terminal is cleared according to the clearing operation of the user.

[0074] Among them, the MAC (Media Access Control Address) of different terminals can be recorded in the historical terminal list. When sending a communication connection request to the terminal to be connected, it can be sent based on the MAC address of the terminal, but not limited to this.

[0075] Step 1024: Use the traversed terminal as the terminal to be connected in turn.

[0076] Here, using the terminals traversed from the historical terminal list as the terminals to be connected in turn to attempt to connect can ensure quickly connecting to the available terminals to quickly resume use.

[0077] For example, assume that the historical terminal list includes five mobile phones, namely mobile phone A, mobile phone B, mobile phone C, mobile phone D, and mobile phone E. The historical terminal list can be traversed, and the traversed mobile phones A, B, C, D, and E are used as the terminals to be connected in turn to send communication connection requests to attempt to connect.

[0078] In an embodiment of the present invention, in order to improve the flexibility of the setting, optionally, before the above step 1023, the method further includes:

[0079] Step 1001: Detect whether a terminal with a preferred connection is set;

[0080] Step 1002: When a terminal with a preferred connection is set, set the terminal with the preferred connection as the first terminal to be traversed in the historical terminal list.

[0081] Here, the mobile phones that the user may often use are relatively fixed for the user. Therefore, it can be set as the terminal with a preferred connection. Every time a communication interruption occurs, the terminal with the preferred connection is used as the first terminal to be traversed in the historical terminal list, that is, the first terminal to attempt to connect during the reconnection process, to facilitate the user's use, so that the user can flexibly set the reconnected terminal and improve the convenience.

[0082] In the prior art, when the mobile phone is out of the range of the in-vehicle unit or the Bluetooth of the mobile phone is abnormal, the time of the data packet reported to the in-vehicle unit is usually within 4-5 seconds. The reconnection occurs after receiving the data packet, and the next connection will be initiated within 6-10 seconds. Therefore, the next connection occurs 15 seconds after the first connection, with a relatively long interval time and a long reconnection waiting time, which affects the experience.

[0083] To shorten the reconnection waiting time, optionally, step 104 includes:

[0084] Step 1044: Start a timer.

[0085] Here, when detecting the interruption of the first communication connection, start a timer to use the timer for timed reconnection and shorten the reconnection waiting time.

[0086] Among them, the timing time of the timer can be set to any value according to requirements. For example, the timing time of the timer can be 2 seconds.

[0087] Step 1045: According to the status of the other communication connection, send a communication connection request to the terminal to be connected.

[0088] Here, after starting the timer, according to the status of the other communication connection, send a communication connection request to the terminal to be connected for reconnection.

[0089] Step 1046: Every time the timing time of the timer is reached, detect whether a communication connection is established with the terminal to be connected.

[0090] Here, every time the timing time of the timer is reached, detect whether a communication connection is established with the terminal to be connected, that is, whether the reconnection is successful. According to the detection result, when the reconnection fails, try to reconnect again.

[0091] Step 1047: When a communication connection is not established with the terminal to be connected, re-execute the step of sending a communication connection request to the terminal to be connected.

[0092] Here, when a communication connection is not established with the terminal to be connected, that is, when the reconnection fails, resend the next communication connection request and try to reconnect again, so as to reconnect once every interval of the timing time of the timer, and the reconnection waiting time can be controlled within a short time.

[0093] Step 1048: When a communication connection is established with the terminal to be connected, turn off the timer.

[0094] Here, when a communication connection is established with the terminal to be connected, that is, when the reconnection is successful, turn off the timer to release resources.

[0095] Step 1049: When the number of times of sending the communication connection request reaches the preset number of times, turn off the timer.

[0096] Here, when the number of times of sending communication connection requests reaches a preset number of times, the timer is turned off and the sending of communication connection requests is stopped, which can ensure the reliability of the reconnection while avoiding unlimited sending and optimizing the solution.

[0097] Among them, the embodiments of the present invention also support setting an upper limit on the automatic reconnection time. Based on this upper limit and the timing time of the timer, the upper limit on the number of times of sending communication connection requests, that is, the preset number of times, can be calculated. For example, assuming that the upper limit on the automatic reconnection time is set to 3 minutes and the timing time of the timer is 2 seconds, the preset number of times can be calculated to be 90 times.

[0098] At this time, by timing the reconnection through the timer, the reconnection waiting time can be shortened, and efficient and fast reconnection can be achieved.

[0099] Optionally, in the above step 1046, the step of detecting whether a communication connection is established with the terminal to be connected includes:

[0100] Step 10461: Detect whether change information on the connection state of the wireless communication physical link is received.

[0101] Here, the premise for establishing a communication connection is the successful connection of the wireless communication physical link. Therefore, every time the timing time of the timer arrives, it is detected whether change information on the connection state of the wireless communication physical link is received to determine whether the communication connection is successfully established.

[0102] Among them, the wireless communication physical link can be, for example, ACL (Asynchronous Connection less), but is not limited thereto.

[0103] Step 10462: When the change information is received, determine whether a communication connection is established with the terminal to be connected according to the change information.

[0104] Here, if change information on the connection state of the wireless communication physical link (such as ACL) is received, it can be determined whether a communication connection is established with the terminal to be connected according to the change information, that is, whether the reconnection is successful.

[0105] Among them, if change information on the connection state of the wireless communication physical link is received and the change information indicates that the wireless communication physical link is successfully connected, it can be determined that a communication connection is established with the terminal to be connected; if the change information indicates that the wireless communication physical link connection fails, it can be determined that a communication connection is not established with the terminal to be connected.

[0106] Taking the wireless communication physical link as an ACL as an example, if the change information of the ACL connection state indicates that the ACL connection is successful, it can be determined that a communication connection is established with the terminal to be connected. If the change information of the ACL connection state indicates that the ACL connection fails, it can be determined that no communication connection is established with the terminal to be connected.

[0107] Step 10463: When the change information is not received, each time the timing time of the timer is reached, the number of times of sending a communication connection request is increased by one, and the step of detecting whether the change information of the wireless communication physical link connection state is received is executed again.

[0108] Here, generally, regardless of whether a communication connection is established with the terminal to be connected, the change information of the wireless communication physical link connection state will be received. If not, there is often a fault or error. In this step, when the change information of the wireless communication physical link connection state is not received, each time the timing time of the timer is reached, it is detected again whether the change information of the wireless communication physical link connection state is received. When the fault or error is recovered, the change information will be received to determine whether the communication connection is successfully established. If the fault or error cannot be recovered, the step of detecting the change information is looped, and the number of times of sending a communication connection request is increased until the number of times of sending a communication connection request accumulates to a preset number, the timer is turned off, and the reconnection is exited.

[0109] At this time, using the change information of the wireless communication physical link connection state, the state of establishing a communication connection can be accurately and quickly determined, improving the processing efficiency.

[0110] The wireless communication connection method of the embodiment of the present invention, as Figure 4 shown, can be applied to the wireless communication connection between the vehicle head unit and the mobile phone, but is not limited thereto.

[0111] A specific application process of the wireless communication connection method of the embodiment of the present invention is illustrated as follows.

[0112] As Figure 2 shown, an application process of the wireless communication connection method of the embodiment of the present invention includes:

[0113] Step 201: Detect that the first communication connection is interrupted.

[0114] Step 202: Start the timer and set the timer timing time to 2 seconds.

[0115] Step 203: According to the requirement, determine whether the vehicle head unit supports multiple terminals to simultaneously connect to different communication protocols of the vehicle head unit. If so, enter Step 204A; if not, enter Step 204B.

[0125] Step 2011A: Increment the number of times of sending the communication connection request by 1, and then proceed to Step 2012A.

[0126] Step 2012A: When the timing time of the timer is reached, detect whether the change information of the ACL connection status is received. If so, proceed to Step 2014A; if not, proceed to Step 2013A.

[0127] Step 2013A: Wait for the next 2 seconds, and then proceed to Step 2011A.

[0128] Step 2014A: According to the change information of the ACL connection status, determine whether the ACL connection is successful. If so, proceed to Step 2015A; if not, return to Step 205A.

[0129] Step 2015A: Turn off the timer and then proceed to Step 2016A.

[0130] Step 2016A: The reconnection is over. Stop sending communication connection requests.

[0131] Step 204B: According to the requirement, when a communication connection interruption occurs at the in-vehicle device end, determine whether it is necessary to reconnect to the entire historical terminal list. If so, proceed to Step 205B1; if not, proceed to Step 205B2.

[0132] Step 205B1: Traverse the historical terminal list, and use the terminals traversed to be the terminals to be connected for each reconnection request in turn. Then proceed to Step 206B.

[0133] Step 205B2: Determine the target terminal corresponding to the first communication connection, and use the target terminal as the terminal to be connected. Then proceed to Step 206B.

[0134] Step 206B: Determine whether the number of times of sending communication connection requests has reached the preset number of times. If so, proceed to Step 2013B; if not, proceed to Step 207B.

[0135] Step 207B: Send a communication connection request to the terminal to be connected via HFP. Then proceed to Step 208B.

[0136] Step 208B: Increment the number of times of sending communication connection requests by 1. Then proceed to Step 209B.

[0137] Step 209B: When the timing time of the timer is reached, detect whether the change information of the ACL connection status is received. If so, proceed to Step 2011B; if not, proceed to Step 2010B.

[0138] Step 2010B: Wait for the next 2 seconds. Then proceed to Step 208B.

[0139] Step 2011B: According to the change information of the ACL connection status, determine whether the ACL connection is successful. If so, proceed to Step 2012B; if not, return to Step 204B.

[0143] The wireless communication connection method according to the embodiment of the present invention will perform reconnection according to the status of other communication connections when a communication connection is interrupted, avoiding disconnection of other connected devices, providing a reconnection solution that supports simultaneous connection of multiple terminals to the in-vehicle unit, ensuring the normal use of multiple communication connections, and meeting the usage requirements of multiple terminals (such as mobile phones) to simultaneously connect to the in-vehicle unit.

[0144] In the embodiment of the present invention, the solution of shortening the reconnection waiting time by timing reconnection through a timer can also be applied when the in-vehicle unit is powered on and connected to the terminal (such as a mobile phone) for the first time to quickly connect to the terminal.

[0145] Such as Figure 3 shown, it is another application process of the wireless communication connection method according to the embodiment of the present invention, including:

[0148] Step 303: According to the requirement, determine whether a terminal with priority connection is set. If so, enter Step 3041; if not, enter Step 3042.

[0149] Step 3041: Use the terminal with priority connection as the first terminal to be traversed in the historical terminal list, and then enter Step 3042.

[0150] Here, the terminal with priority connection can be directly set at the top of the historical terminal list.

[0151] Step 3042: Traverse the historical terminal list, and use the traversed terminal as the terminal to be connected for each connection request in turn, and then enter Step 305.
