Detailed Description
The structural and operational principles of the present invention are further described in detail below with reference to the accompanying drawings.
As shown in fig. 2, a method for preventing a bluetooth headset and a bluetooth terminal from entering a narrow band during a call, which is suitable for the bluetooth headset and the bluetooth terminal, comprises the following steps:
1) establishing a broadband SLC Service Level Connection (Service Level Connection) between the Bluetooth headset and the Bluetooth terminal;
2) the Bluetooth terminal sends information to inform the Bluetooth headset of incoming call or outgoing call;
3) the Bluetooth headset preferentially replies an AT _ BCS instruction to the Bluetooth terminal, and a broadband SCO Oriented Synchronous Connection (synchronized Connection ordered) is established between the Bluetooth headset and the Bluetooth terminal.
The Bluetooth headset is enabled to preferentially reply an AT _ BCS Bluetooth coding and decoding Selection (Bluetooth code Selection) instruction to the Bluetooth terminal, so that no other private AT instruction exists in an AT sending queue before the AT _ BCS Bluetooth coding and decoding Selection (Bluetooth code Selection) instruction is replied, the AT + BCS instruction can complete negotiation within 500ms, broadband SCO (Synchronous Connection ordered) is established between the Bluetooth headset and the Bluetooth terminal, and the Bluetooth headset is prevented from being blacklisted by the Bluetooth terminal, so that a user can use the Bluetooth headset to carry out high-definition call, and a more real, natural and comfortable voice effect is presented to the consumer.
As a preferable scheme, the bluetooth terminal sends information to inform the bluetooth headset that there is an incoming call or an outgoing call, and simultaneously initiates a call negotiation to the bluetooth headset.
As shown in fig. 3, a method for establishing an SLC Service Level Connection (Service Level Connection) between a bluetooth headset and a bluetooth terminal includes the following steps:
1) the Bluetooth earphone sends a function (Bluetooth regenerative Supported feeds) instruction Supported by AT _ BRSF Bluetooth detection to the Bluetooth terminal;
2) the Bluetooth terminal feeds back information to the Bluetooth headset;
3) the Bluetooth headset replies an AT _ BCS Bluetooth coding and decoding Selection (Bluetooth code Selection) instruction to the Bluetooth terminal, and a broadband SLC Service Level Connection (Service Level Connection) is established between the Bluetooth headset and the Bluetooth terminal.
Because the instruction of the function (Bluetooth Supported Features) Supported by the AT + BRSF Bluetooth detection is the first AT command of the Bluetooth headset, when the AT instruction is sent by the front end, no other AT command is inserted AT this time, because the Bluetooth headset is not yet Bluetooth connected, it can be guaranteed to be completed within 100ms under normal environment.
As a preferred scheme, before sending a function (Bluetooth Supported Features) instruction Supported by AT _ BRSF Bluetooth detection to the Bluetooth terminal, the Bluetooth headset enters an AT detection module normal operation (Attention) mode.
As a preferred scheme, the key of sending a function (Bluetooth Supported Features) instruction Supported by AT _ BRSF Bluetooth detection to the Bluetooth terminal by the Bluetooth headset is: the bluetooth headset sends the features that it can support to the bluetooth terminal.
As a preferred scheme, the key of the feedback information from the bluetooth terminal to the bluetooth headset is as follows: the bluetooth terminal transmits the features that it can support to the bluetooth headset.
As a preferred scheme, the Bluetooth terminal is a mobile phone, a PDA or a computer.
Experimental example 1:
verifying the method for preventing the communication between the Bluetooth earphone and the Bluetooth terminal from entering the narrow band
The verification method comprises the following steps:
1) the Bluetooth headset sends an AT _ BRSF instruction to the Bluetooth terminal;
2) the Bluetooth terminal feeds back information to the Bluetooth headset;
3) the Bluetooth earphone replies an AT _ BCS instruction to the Bluetooth terminal, and the Bluetooth earphone and the Bluetooth terminal establish broadband SLC connection.
4) The mobile phone sends information to inform the Bluetooth headset of incoming call or outgoing call, and initiates conversation negotiation to the Bluetooth headset;
5) enabling the Bluetooth headset to preferentially reply an AT _ BCS instruction to the mobile phone;
6) capturing and analyzing an air interface packet and a Bluetooth headset running Log to confirm whether SCO connection established between the Bluetooth headset and a mobile phone is a narrow band or a wide band;
7) closing the Bluetooth of the mobile phone end, and restoring the network setting of the mobile phone; and (5) connecting the Bluetooth headset again, and circulating the steps for 100 times.
And (4) verification result:
as can be seen from fig. 4, when a call negotiation is performed between the bluetooth terminal and the bluetooth headset, the bluetooth headset preferentially replies to the AT _ BCS command, so that the SCO connection established between the bluetooth headset and the mobile phone is a broadband (mSBC).
The invention has the beneficial effects that: through making establish the broadband SLC connection between bluetooth terminal and the bluetooth headset and when carrying out the conversation negotiation between bluetooth terminal and bluetooth headset, make bluetooth headset preferred reply AT _ BCS instruction, can ensure to establish the broadband SCO connection between bluetooth headset and the bluetooth terminal to can avoid bluetooth headset to be squeezed into the blacklist by bluetooth terminal, make the user can use bluetooth headset to carry out the high definition conversation, present more true, natural, comfortable speech effect for the consumer.
The above description is only a preferred embodiment of the present invention, and all the minor modifications, equivalent changes and modifications made to the above embodiment according to the technical solution of the present invention are within the scope of the technical solution of the present invention.
