[0027] The technical solution of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] Bluetooth is a radio technology that supports short-range communication between devices, and can exchange information wirelessly between peripherals including mobile phones, wireless headphones, laptops, etc. The existing technical solutions for controlling mobile phone calls and music playback based on Bluetooth chips require two Bluetooth chips, which is costly and has a large sound delay.

[0029] Based on this, the embodiments of the present application provide a channel control method, device and system. After the call host controls the headset to connect to the mobile phone network, the headset is controlled through custom instructions to perform channel operations corresponding to preset channel operation instructions, so as to realize the switching of the mobile phone channel between the headset and the call host, with small sound delay and low cost.

[0030] To facilitate understanding of this embodiment, a channel control method disclosed in an embodiment of the present application is first introduced in detail.

[0031] Figure 1 A flow chart of a channel control method provided in an embodiment of the present application, the method is applied to a call host; in this embodiment, the call host includes a Bluetooth chip, the call host DUT (Device Under Test) ) Refers to the base (Base) of the Bluetooth headset, the phone, etc., that is, the call host. The headset can be charged when placed on the DUT. When the Bluetooth function is turned on, the call host is usually connected to the headset and the mobile phone; the above-mentioned channel control method specifically includes the following steps:

[0032] Step S102, controlling the headset to establish a connection with the mobile phone;

[0033] Before the channel control, the DUT must first control the headset to actively establish a connection with the mobile phone, and the DUT, mobile phone, and headset are interconnected in pairs. As the central control point, the DUT can collect the connection status of the headset-mobile phone and DUT-mobile phone, so as to determine whether the three are interconnected.

[0034] Step S104, after determining that the mobile phone and the headset are connected, sending a first custom instruction to the headset to notify the headset to enter the interactive mode;

[0035] After the DUT determines that the interconnection of the three devices is complete, it notifies the headset to enter the interactive mode through the custom instruction 1. At this time, the DUT regards the headset as an audio device equal to itself, and the two are integrated with each other.

[0036] Step S106, sending a preset channel operation instruction to the headset, so that the headset performs the channel operation corresponding to the preset channel operation instruction, so as to achieve the switching of the mobile phone channel between the headset and the call host.

[0037] The above-mentioned mobile phone channels include mobile phone voice channels and mobile phone music channels; the earphone receives and executes the customized channel operation instructions issued by the DUT, and the DUT receives the channel status information of the earphone. The switching of the mobile phone channel in the DUT earphone is converted into a coordinated operation between the DUT and the earphone.

[0038] In the channel control method provided in the embodiment of the present application, when only one Bluetooth chip is used, the DUT and the headphones work together to implement the function of switching mobile phone calls and music channels between the DUT and the headphones, thereby solving the problems of high cost and high latency.

[0039] The embodiment of the present application also provides another channel control method, which is implemented on the basis of the above embodiment; this embodiment focuses on describing the specific mobile phone channel switching process.

[0040] See also Figure 2 As shown, the three devices, DUT, mobile phone and headset, are interconnected. DUT notifies the headset to enter the interactive mode through custom instruction 1. At this time, the mobile phone channel can be switched.

[0041] (1) The process of switching the mobile phone voice channel from the DUT to the headset is as follows:

[0042] See also Figure 3 As shown, the above-mentioned preset channel operation instructions include: a second custom instruction, namely custom instruction 2; after the DUT disconnects the voice connection with the mobile phone, it sends the second custom instruction to the headset, so that the headset sends a voice connection request to the mobile phone according to the second custom instruction, so that the voice channel of the mobile phone is switched to the headset; at this time, the headset can directly answer the mobile phone call.

[0043] Of course, the above process may also not execute the step of disconnecting the voice connection with the mobile phone, and directly switch the mobile phone voice channel from the DUT to the headset according to the second custom instruction.

[0044] (2) The process of switching the mobile phone voice channel from the headset to the DUT is as follows:

[0045] See also Figure 4 As shown, the above-mentioned preset channel operation instructions also include: a third custom instruction, namely, custom instruction 3; the DUT first sends the third custom instruction to the headset, so that the headset disconnects the voice connection with the mobile phone according to the third custom instruction; then receives the fourth custom instruction returned by the headset after the voice connection is disconnected, namely, custom instruction 4, and establishes a voice connection with the mobile phone, so that the voice channel of the mobile phone is switched back to the call host, and the DUT can directly answer the mobile phone call.

[0046] (3) The process of switching the mobile phone music channel from the DUT to the earphone is as follows:

[0047] See also Figure 5As shown, the above-mentioned preset channel operation instructions also include: a fifth custom instruction, namely custom instruction 5; the DUT first sends a pause music command (such as an AVRCP pause command) to the mobile phone to make the mobile phone stop playing music, and then sends a fifth custom instruction to the headset, such as custom instruction 5, so that the headset sends a play Bluetooth music command (AVRCP play command) to the mobile phone according to the fifth custom instruction to control the mobile phone to start playing music, thereby switching the mobile phone music channel to the headset, and then only the headset can hear the mobile phone music.

[0048] AVRCP is a protocol used to control media audio and video playback via Bluetooth. It supports the DUT / headphones to send AVRCP play / pause (or stop) commands to the mobile phone to control the mobile phone's music playback / stop playback operations. Changes in the mobile phone's music playback status will notify the DUT or headphones.

[0049] (4) The process of switching the mobile phone music channel from the earphone to the DUT is as follows:

[0050] See also Figure 6 As shown, the above-mentioned preset channel operation instructions also include: a sixth custom instruction, namely custom instruction 6; the DUT first sends the sixth custom instruction to the headset, so that the headset sends a pause Bluetooth music command to the mobile phone to control the mobile phone to stop playing music; receives the seventh custom instruction returned by the headset, namely custom instruction 7, and sends a play Bluetooth music command to the mobile phone to make the mobile phone start playing music, so as to switch the mobile phone music channel back to the call host. At this time, only the DUT can hear the mobile phone music.

[0051] Furthermore, the transmission mode of the above-mentioned custom instruction includes one of the following: HFP protocol transmission, AVRCP protocol transmission, SPP protocol transmission, BLE protocol transmission, and A2DP protocol transmission.

[0052] HFP: The full name is Hands-free Profile, which is a protocol that allows Bluetooth devices to control phone calls, such as answering, hanging up, rejecting, voice dialing, etc. BLE: Low-power Bluetooth technology. SPP: Bluetooth serial port protocol, a protocol that can create a virtual serial port between Bluetooth devices for data transmission. AVRCP: Audio / video remote control specification, mainly used for Bluetooth control of media audio and video playback. A2DP: Bluetooth audio transmission model protocol specification, used for multimedia audio data transmission.

[0053] The channel control method provided in the embodiment of the present application establishes a data transmission channel between the DUT, the headset, and the mobile phone. Through custom instructions between the DUT and the headset, the headset can be disconnected and connected, and the channel status can be synchronized to the DUT, etc. The DUT uniformly manages the local and headset channel operations, and the mobile phone channel is transferred between the DUT and the headset by disconnecting and connecting. In this method, by introducing the channel cooperative control operation between the DUT and the headset, the mobile phone Bluetooth channel can be switched between the DUT and the headset without relying on the DUT Bluetooth chip capabilities, while reducing the sound delay.

[0054] In addition, the switching of voice call channels not only includes the method of disconnecting the channels first and then connecting the channels as described above, but also includes allowing the target device to directly connect to the voice channel and directly play music via AVRCP to achieve channel transfer.
