Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and more specifically, to a Bluetooth earphone and a method for connecting the earphone to a smart device. Background Art

[0002] With the development of wireless communication technology, true wireless Bluetooth headsets have been widely used. Among them, the speed at which Bluetooth headsets reconnect to previously connected smart devices such as mobile phones is an important performance indicator that affects user experience. However, when current headsets reconnect to mobile phones, only the right headset, for example, acts as the main headset to attempt to reconnect to the mobile phone, rather than both the left and right ears trying to connect to the headsets at the same time. This approach may slow down the speed of reconnecting to the mobile phone, and in some cases may also result in failure to successfully connect to the desired mobile phone. Summary of the invention

[0003] The present application is provided to solve the above-mentioned problems existing in the prior art.

[0004] A Bluetooth earphone and a method for connecting the earphone to a smart device are needed, which have a faster connection speed and a higher connection success rate when the Bluetooth earphone is connected back to the smart device.

[0005] According to a first aspect of the present application, a method for connecting a Bluetooth headset to a smart device is provided, wherein any one of the Bluetooth headsets serves as a master headset and the other serves as a slave headset, and a first wireless link is provided between the master headset and the slave headset. The method comprises: when the Bluetooth headset is to be connected to a single target smart device, the master headset and the slave headset negotiate via the first wireless link to determine a start paging time slot and a number of candidate smart devices that can be attempted to be connected in order of priority; when the start paging time slot arrives, the master headset and the slave headset synchronously initiate paging of a first smart device with the highest priority among the number of candidate smart devices; when the master headset or any one of the slave headsets successfully establishes a first Bluetooth connection with the first smart device, the first smart device is used as the single target smart device and the other headset stops paging the first smart device.

[0006] According to a second aspect of the present application, a Bluetooth headset is provided, wherein any one of the Bluetooth headsets is used as a master headset, and the other headset is used as a slave headset, and a first wireless link is provided between the master headset and the slave headset. When the Bluetooth headset is to be connected to a single target smart device, the first wireless link is configured as follows: the master headset and the slave headset negotiate via the first wireless link to determine a start paging time slot and a number of candidate smart devices that can be attempted to be connected in order of priority; the master headset is configured as follows: when the start paging time slot arrives, the master headset synchronously initiates a connection to a first smart device with the highest priority among the number of candidate smart devices, The slave earphone is configured to paging a first smart device with the highest priority among the candidate smart devices synchronously with the master earphone when the paging start time slot arrives, and, in the case that the master earphone successfully establishes a first Bluetooth connection with the first smart device before the slave earphone, the first smart device is used as the single target smart device and the paging of the first smart device is stopped. The slave earphone is configured to: when the paging start time slot arrives, paging the first smart device with the highest priority among the candidate smart devices is synchronously initiated with the master earphone, and, in the case that the master earphone successfully establishes a first Bluetooth connection with the first smart device before the slave earphone, the first smart device is used as the single target smart device and the paging of the first smart device is stopped.

[0007] According to the Bluetooth earphones and the method for connecting to a smart device according to the various embodiments of the present application, the two earphones pre-negotiate to determine the smart device to be connected through the wireless link between the earphones, and attempt to synchronously page the smart device in the same paging time slot.

[0016] Figure 1 FIG. 1 is a schematic diagram showing the structure of a Bluetooth earphone and its peripheral components according to an embodiment of the present application. Figure 1 As shown, either earphone of the two earphones of the Bluetooth earphone 100 can be used as the master earphone, and the other earphone can be used as the slave earphone accordingly, and the master earphone and the slave earphone can switch roles when appropriate. Figure 1 The right earphone 101 is used as the master earphone, the left earphone 102 is used as the slave earphone, and there is a first wireless link 103 between the right earphone 101 and the left earphone 102. In some embodiments, the first wireless link 103 may be a Bluetooth link or a WiFi link, or may be other applicable wireless links, for example, based on a private protocol, which is not limited in the present application.

[0017] In some embodiments, the Bluetooth headset 100 can perform Bluetooth communication with at least one smart device. For example, the right earphone 101 and the smart device 104 can directly perform Bluetooth communication via the Bluetooth connection 105, while the left earphone 102 obtains the relevant parameter information of the smart device 104 and the Bluetooth connection 105 via the first wireless link 103, thereby obtaining Bluetooth data from the smart device 104 by monitoring the Bluetooth connection 105, thereby realizing Bluetooth communication between the Bluetooth headset 100 and the smart device 104. In other embodiments, the Bluetooth communication between the two earphones of the Bluetooth headset 100 and the smart device 104 can also be performed in other ways. As an example only, for example, the right earphone 101 can be used as the master earphone, and the Bluetooth data received from the smart device 104 via the Bluetooth connection 105 is forwarded to the left earphone 102 as the slave earphone via the first wireless link 103. The present application does not limit the specific method, as long as the two earphones can synchronously receive the Bluetooth data from the smart device.

[0018] In other embodiments, the Bluetooth headset 100 can establish and maintain Bluetooth connections with more than one smart device, and perform Bluetooth communications with multiple smart devices simultaneously or in a time-sharing manner. For example, while listening to Bluetooth music from the smart device 104 via the Bluetooth connection 105, the Bluetooth headset 100 can also perform Bluetooth communications with multiple smart devices via other Bluetooth connection links ( Figure 1 Not shown) to answer calls from other smart devices ( Figure 1 The telephone audio (not shown) and so on are not listed here.

[0019] In some embodiments, the Bluetooth headset 100 can be in-ear, non-in-ear (e.g., bone conduction) or semi-in-ear, and this application does not limit this. The smart device 104 can be, for example, a mobile phone, a pad, a personal computer, a wearable device, etc., and this application does not limit this, as long as it has a Bluetooth interface and can connect to a Bluetooth headset.

[0020] According to an embodiment of the present application, a method for connecting a Bluetooth headset to a smart device is provided. It is worth noting that the method for connecting a Bluetooth headset to a smart device provided in the present application is applicable to the process of reconnecting (or "reconnecting" or "reconnecting") to the target smart device through paging (page, also called "connection"), under the premise that at least one headset in the Bluetooth headset has completed Bluetooth pairing with the target smart device and has performed Bluetooth communication (the headset knows the pairing information of the target smart device including address information and pairing key). The state of the headset paging the target smart device is called the Page substate, and correspondingly, the target smart device is in the paging scan (Page scan) substate. As an example only, the paging headset and the paged smart device use specific bits of the paged device address (e.g., the lower 28 bits) to generate a paging-hopping sequence, which is a well-defined periodic sequence with frequencies evenly distributed on the 79 frequency channels of 2.4 GHz. When the headset is paging, for example, it can select a new frequency to send a page every 312.5 μs, while the paged smart device in the paging scanning state can select a new monitoring frequency every 1.28 s. When the paging and paged frequencies are the same, the headset can be successfully connected to the smart device.

[0021] Figure 2 A schematic diagram showing a flow chart of a method for connecting a Bluetooth earphone to a single target smart device according to an embodiment of the present application. Figure 2 As shown, the process of connecting the Bluetooth earphone to a single target smart device is completed by executing steps 201 to 203.

[0022] First, in step 201, the master headset and the slave headset negotiate via the first wireless link to determine a start paging time slot and a number of candidate smart devices to which connection can be attempted in order of priority.

[0023] Then, in step 202, when the start paging time slot arrives, the master headset and the slave headset synchronously initiate paging to the first smart device with the highest priority among the plurality of candidate smart devices.

[0024] Next, in step 203, when the master earphone or any one of the slave earphones successfully establishes the first Bluetooth connection with the first smart device, the first smart device is used as the single target smart device and the other earphone stops paging the first smart device. After any one of the two earphones successfully establishes the first Bluetooth connection with the target smart device, for example, in the aforementioned manner, the Bluetooth address, encryption method and other Bluetooth communication parameter information of the target smart device can be notified to the other earphone that failed to connect directly through the first wireless link between the earphones, so that the other earphone can monitor the first Bluetooth connection according to the Bluetooth communication related parameter information to obtain Bluetooth data.

[0025] According to the method of connecting a Bluetooth earphone to a smart device according to an embodiment of the present application, the smart device to be connected is determined by pre-negotiation through the wireless link between the earphones, and the smart device is attempted to be paged synchronously in the same paging time slot. Compared with the prior art in which only the main earphone is used to connect to the smart device, not only is the probability of the earphone successfully connecting back to the smart device higher, but the time it takes to connect back to the smart device can also be shortened, that is, it has a faster connection speed, and therefore also has a better user experience. In addition, due to the time-division multiplexing feature of Bluetooth communication for time slots, when the main earphone is paging the smart device, it cannot communicate between the two ears with the slave earphone at the same time, and because the slave earphone cannot independently receive data from other smart devices without the cooperation of the main earphone, when the time slot of the main earphone is used to paging the smart device, the slave earphone and the main earphone synchronously page the smart device, which is a relatively more efficient way to utilize bandwidth resources.

[0026] In other embodiments, since in step 201, the candidate smart devices determined by the two earphones through the first wireless link negotiation may be more than one, therefore, in the case that both the master earphone and the slave earphone fail to successfully connect to the candidate smart device of the current priority, the master earphone and the slave earphone may synchronously initiate paging to the candidate smart device of the next priority in the next paging time slot. In this way, without having to occupy more communication resources and time slots of the first wireless link, only through the initial one-time negotiation, the synchronous connection to the target smart device can be attempted in a compact manner in the subsequent process, so that the reconnection time between the Bluetooth earphone and the smart device can be further shortened.

[0027] Figure 3 A schematic diagram of the information interaction process of connecting a Bluetooth headset to a single target smart device according to an embodiment of the present application is shown. Figure 3As shown, the Bluetooth earphone 100 includes a right earphone 101 and a left earphone 102. In step S301, the right earphone 101 and the left earphone 102 can establish a first wireless link to achieve connection between the ears, and use the first wireless link to communicate to agree that one of the earphones is the master earphone, for example, the right earphone 101 is the master earphone, and the other left earphone 102 is the slave earphone. Usually, the master earphone is connected to a smart device such as a mobile phone through Bluetooth and receives Bluetooth data, but this is not necessary. In other embodiments, the slave earphone can also be connected to the smart device through Bluetooth under pre-agreed conditions.

[0028] Next, in step S302, the master earphone and the slave earphone negotiate via the first wireless link to determine the start of the paging time slot and the number of candidate smart devices that can be attempted to connect in order of priority. Specifically, the slave earphone (left earphone 102) sends the smart device connection history list of the slave earphone to the master earphone (right earphone 101) via the first wireless link, and the master earphone combines the smart device connection history list of the master earphone and the smart device connection history list of the slave earphone to determine the number of candidate smart devices that can be attempted to connect and their corresponding priorities. As mentioned above, each earphone will save the relevant information of the smart devices that have been successfully connected and communicated in the smart device connection history list. For example, Figure 3 As shown, both the smart device connection history list of the right earphone 101 and the smart device connection history list of the left earphone 102 only include one item of mobile phone A. Therefore, in step S302, the candidate smart device determined by the main earphone (right earphone 101) to be attempted to connect is only mobile phone A. In some other embodiments, in addition to the address of each smart device, the smart device connection history list may also include the connection frequency and connection time information of each smart device. In this case, step S302 may further include: the main earphone selects several candidate smart devices that can be attempted to connect from the intersection of the smart device connection history list of the main earphone and the smart device connection history list of the slave earphone, and sets the corresponding priority of each candidate smart device according to the connection frequency and / or connection time. As an example only, the specific number of the above-mentioned several candidate smart devices can be pre-set as needed, and this application does not limit this. In terms of setting the priority, for example, the smart device that the main earphone and / or the slave earphone have been recently connected to can be set to have a higher priority. Independently or additionally, the smart device with a higher connection frequency in the two earphones can also be set to have a higher priority. In other embodiments, different weights can be set for different connection frequencies and connection times, thereby calculating the weighted priority of each smart device in the intersection of the smart device connection history lists of the master and slave headphones and sorting them according to the priority so that they can be paged in sequence in subsequent steps. The specific priority calculation method is not limited in this application.

[0029] In addition, in step S302, it is also necessary to negotiate and determine the start paging time slot for starting to paging the candidate smart device via the first wireless link. The specific process may include: the slave earphone sends the communication time slot of the slave earphone to the master earphone via the first wireless link, and then the master earphone determines the start paging time slot by combining the communication time slot of the master earphone and the communication time slot of the slave earphone. As an example only, when at least one of the master earphone or the slave earphone controlled by the master earphone is currently performing other communication tasks and there are not enough available time slots to initiate paging to the smart device, the start paging time slot is not necessarily set to the nearest paging time slot, and the start paging time slot can also be set to a future paging time slot by predicting that both earphones have available time slots at the same time.

[0030] Next, when the start paging time slot arrives, the right earphone 101 and the left earphone 102 synchronously page the mobile phone A in step S303 and step S303', respectively. In some embodiments, the master and slave earphones can use frequencies in different frequency sequences for paging, so as to avoid mutual interference between the same paging frequencies during synchronous paging, and also increase the probability of encountering the monitoring frequency of the paged mobile phone A in the page scan mode, thereby further improving the paging success rate and shortening the connection establishment time between the Bluetooth earphone and the smart device.

[0031] Figure 3 The A1 box, A2 box and A3 box shown in the figure are three possible subsequent steps after the right earphone 101 and the left earphone 102 start synchronous paging. The A1 box shows the situation where the master earphone first successfully pages. In step S304, the right earphone 101 as the master earphone pages to mobile phone A and establishes a Bluetooth connection with mobile phone A, and in step S305, the left earphone 102 as the slave earphone is notified via the first wireless link to cancel paging mobile phone A. After receiving the information, the left earphone 102 stops paging mobile phone A. At this point, the Bluetooth earphone completes the process of connecting back to mobile phone A.

[0032] In other cases, as shown in box A2, in step S304a, the left earphone 102, which serves as a slave earphone, first pages mobile phone A and establishes a Bluetooth connection with mobile phone A. Then, in step S305a, the right earphone 101, which serves as the master earphone, is informed via the first wireless link to cancel paging mobile phone A. After receiving the message, the right earphone 101 stops paging mobile phone A, and in step S306, the left earphone 102 is informed via the first wireless link that it has stopped paging mobile phone A. After receiving the indication information, the left earphone 102 can initiate the role switching of the master and slave earphones via the first wireless link. After the switching, the left earphone 102, as the master earphone, directly communicates with mobile phone A via Bluetooth, while the right earphone 101, as the slave earphone, synchronously receives Bluetooth data from mobile phone A, for example, by monitoring the Bluetooth connection between the master earphone and mobile phone A.

[0033] In frame A3, the right earphone 101 and the left earphone 101 fail to successfully connect to the mobile phone A after the preset paging time (e.g., 5s) ends, that is, the paging timeout occurs. In this case, the Bluetooth earphones can perform other UX according to the process predefined by the protocol, such as re-pairing after timeout, or repeating the paging timeout. Figure 3 The present application does not impose any specific limitation on the various steps shown in the present application.

[0034] exist Figure 3 In steps S305, S305a, S306, etc., when one earphone is first successfully connected to the paged smart device, it promptly informs the other earphone to cancel the paging of the smart device, so that the other earphone can release the bandwidth resources occupied by the paging, thereby quickly switching to the exchange of Bluetooth connection information of the smart device through the first wireless link between the earphones, or starting subsequent steps such as master-slave role switching, thereby avoiding the waste of time slots and bandwidth resources.

[0035] In addition, in order to enable the Bluetooth earphone to better support the method for connecting to a smart device according to an embodiment of the present application, after the Bluetooth earphone is successfully paired with a new smart device (that has not been connected before) and connected for communication, regardless of whether the earphone is connected to the smart device as the main earphone, the address of the smart device can be stored in the earphone's smart device connection history list, and the Bluetooth communication-related parameters corresponding to the smart device can be stored together, so that paging to the same smart device can be initiated synchronously with another earphone in the future.

[0036] In other cases, the Bluetooth earphones can also support maintaining connections with multiple target smart devices at the same time. Figure 4 A schematic diagram showing a flow chart of a method for connecting a Bluetooth headset to multiple target smart devices according to an embodiment of the present application.

[0037] like Figure 4As shown, in the case where a Bluetooth earphone is to be connected to multiple target smart devices, first, in step 401, the master earphone and the slave earphone negotiate via the first wireless link to determine that the master earphone first pages the second smart device among the multiple target smart devices in a unified paging time slot, and the slave earphone first pages the third smart device among the multiple target smart devices that is different from the second smart device.

[0038] Next, in step 402, when the unified paging time slot arrives, the master headset and the slave headset initiate paging to the second smart device and the third smart device respectively;

[0039] In step 403, when the master headset is successfully connected to the second smart device and the slave headset has not yet successfully connected to the third smart device, the master headset assists in paging the third smart device. Conversely, when the slave headset is successfully connected to the third smart device and the master headset has not yet successfully connected to the second smart device, the slave headset assists in paging the second smart device.

[0040] Compared with the prior art of sequentially paging multiple target smart devices to be connected, in the above steps 401-403 of the present application, since the two earphones independently initiate paging to different smart devices, when one of them cannot be successfully connected due to reasons such as the smart device being paged is not in the connectable range, it will not affect the connection speed of the other earphone to the other smart device. In addition, when one of the earphones first completes the connection to the smart device assigned to it, it can also enter the process of paging the smart device to be connected together with the other earphone, thereby further speeding up the speed of the Bluetooth earphone connecting to multiple target smart devices.

[0041] Similar to connecting a single target smart device, in the process of determining the second smart device to be connected to the master earphone and the third smart device to be connected to the slave earphone, the slave earphone can first send the smart device connection history list of the slave earphone to the master earphone via the first wireless link, wherein the smart device connection history list contains the connection frequency and connection time information of each smart device; then, the master earphone determines the intersection of the smart device connection history list of the master earphone and the smart device connection history list of the slave earphone, and takes the smart devices in the intersection as the multiple target smart devices, and determines the second smart device according to the connection frequency and / or connection time of each target smart device in the smart device connection history list of the master earphone; and determines the third smart device according to the connection frequency and / or connection time of each target smart device in the smart device connection history list of the slave earphone. Specifically, since the master earphone and the slave earphone page different smart devices respectively, when selecting the second smart device, the connection frequency and / or connection time of the smart device in the smart device connection history list of the master earphone should be considered; when selecting the third smart device, the connection frequency and / or connection time of the smart device in the smart device connection history list of the slave earphone should be considered. In this way, the efficiency of the two earphones connecting to the smart devices can be maximized, and the overall time for the Bluetooth earphone to connect to multiple target smart devices can be shortened.

[0042] According to an embodiment of the present application, a Bluetooth headset is also provided, and its composition structure has been combined with Figure 1 According to the embodiment of the present application, any one of the Bluetooth earphones can be used as the master earphone, and the other earphone can be used as the slave earphone. There is a first wireless link between the master earphone and the slave earphone. When the Bluetooth earphone is to be connected to a single target smart device, the first wireless link is configured as follows: the master earphone and the slave earphone negotiate via the first wireless link to determine the start of the paging time slot and a number of candidate smart devices that can be attempted to be connected in order of priority.

[0043] The master earphone configuration may be: when the paging start time slot arrives, paging the first smart device with the highest priority among the candidate smart devices is initiated synchronously with the slave earphone, and when the slave earphone successfully establishes the first Bluetooth connection with the first smart device before the master earphone, the first smart device is used as the single target smart device and paging of the first smart device is stopped.

[0044] The slave earphone can be configured to: when the paging start time slot arrives, synchronously with the master earphone initiate paging to the first smart device with the highest priority among the several candidate smart devices, and when the master earphone successfully establishes the first Bluetooth connection with the first smart device before the slave earphone, the first smart device is used as the single target smart device and the paging of the first smart device is stopped.

[0045] When the Bluetooth earphone according to the embodiment of the present application is to connect to multiple target smart devices, the first wireless link can be further configured as follows: the master earphone and the slave earphone negotiate via the first wireless link to determine that in a unified paging time slot, the master earphone first pages the second smart device among the multiple target smart devices, and the slave earphone first pages the third smart device among the multiple target smart devices that is different from the second smart device.

[0046] The master earphone can be further configured to initiate paging to the second smart device when the unified paging time slot arrives, and to assist in paging the third smart device by the master earphone when the master earphone is successfully connected to the second smart device and the slave earphone has not yet successfully connected to the third smart device.

[0047] The slave earphone can be further configured to: when the unified paging time slot arrives, the slave earphone initiates paging to the third smart device, and when the slave earphone is successfully connected to the third smart device and the master earphone has not yet successfully connected to the second smart device, the slave earphone assists in paging the second smart device.

[0048] It is worth noting that, since any earphone in the Bluetooth earphone can assume the role of the master earphone and the role of the slave earphone, the configurations of the two earphones are actually exactly the same, but they perform different operations when assuming different roles.

[0049] In some other embodiments, the master headset and the slave headset may also be configured to have a memory or storage area ( Figure 1), for example, it can be used to store the respective smart device connection history lists. The above-mentioned memory / storage area can be a non-temporary computer-readable medium, such as a read-only memory (ROM), a random access memory (RAM), a phase change random access memory (PRAM), a static random access memory (SRAM), a dynamic random access memory (DRAM), an electrically erasable programmable read-only memory (EEPROM), other types of random access memory (RAM), a flash disk or other forms of flash memory, a cache, a register, a static memory, a compact disk read-only memory (CD-ROM), a digital versatile disk (DVD) or other optical memory, a cassette or other magnetic storage device, or any other possible non-temporary medium used to store information or instructions that can be accessed by a computer device.

[0050] In the implementation process, each step of the method for connecting the above-mentioned Bluetooth earphone to the smart device can be completed by the hardware processor or integrated logic circuit or software instructions in each earphone of the Bluetooth earphone. The steps of the method disclosed in the embodiment of the present application can be directly embodied as loading the instructions stored in the non-temporary computer-readable medium into the hardware processor or integrated logic circuit in the earphone for execution, or by a combination of a hardware processor, an integrated logic circuit and a software module. The software module can be located in a mature storage medium in the field such as a random access memory, a flash memory, a read-only memory, a programmable read-only memory or an electrically erasable programmable memory, a register, etc. Among them, the hardware and software for executing the method according to the embodiment of the present application can also be uniformly implemented by the system on chip (SoC) in each earphone. To avoid repetition, it is not described in detail here.

[0051] Furthermore, although exemplary embodiments have been described herein, the scope thereof includes any and all embodiments based on the present application having equivalent elements, modifications, omissions, combinations (eg, schemes that cross various embodiments), adaptations, or changes.
