Link manager 190 is responsible for receiving order and the data that upper layer module sends, and the result is returned to the upper strata.Link manager 190 is finished function corresponding by baseband controller 150 and bluetooth radio 160.LMP Link Manager Protocol 140 is used for the intercommunication mutually between the different Bluetooth devices link manager.Baseband controller 150 is according to the command operation of link manager 190.Bluetooth radio 160 wirelessly sends and receives information according to the specification of standard.
Fig. 2 explains to press earphone keystroke as the user in earpiece application framework (Headset Profile), carries out the message flow diagram of relevant action.When the user pushes button (U210), if do not have linking bluetooth between earphone and the blue tooth voice gateway, then set up bluetooth asynchronous transmission link (S210), send signaling AT+CKPD to blue tooth voice gateway (S220).Blue tooth voice gateway is replied earphone OK (S230).Blue tooth voice gateway foundation links (S240) with the bluetooth synchronous transmission of earphone.S230 and S240 order are indefinite.So far, earphone just and set up between the blue tooth voice gateway and got well voice channel.After this, when the user pushes button (U220) once more, have linking bluetooth between earphone and the blue tooth voice gateway, earphone sends signaling AT+CKPD to blue tooth voice gateway (S250), and blue tooth voice gateway is replied earphone OK (S260).Blue tooth voice gateway is removed bluetooth synchronous transmission link (S270) and bluetooth asynchronous transmission link (S280).S260 and S270 order are indefinite.This shows that in earpiece application framework (Headset Profile), the earphone end can't carry out the refusing to receive telephone operation.Earphone can't obtain information such as incoming information, current time by the standard signaling, need realize by the AT signaling of expansion.
What Fig. 3 explained is the message flow diagram that realizes caller identification and refusing to receive telephone function by the present invention.Blue tooth voice gateway is mobile phone normally in the present invention.Have telephone directory in the mobile phone, mobile phone can be learnt incoming person's name according to the telephone number of incoming call.Incoming information among the present invention shows to be exactly a kind of function that the incoming information of mobile phone end is shown at the earphone end.After blue tooth voice gateway is received an incoming call request, just set up the bluetooth asynchronous transmission and link (s310) with the good earphone of prior pairing.After link foundation was finished, bluetooth earphone sent AT expanded signalling request incoming information (s320) to blue tooth voice gateway.After blue tooth voice gateway receives signaling, incoming informations such as telephone number and name are sent to bluetooth earphone (s330).After bluetooth earphone is received incoming information, just it is shown on LCDs (s340).
After the user saw incoming information, the flow process that the user receives calls belonged to the standard criterion that bluetooth earphone is used.Except answering button, special rejection button is arranged at the bluetooth earphone end.The user presses (u310) behind the rejection key, and bluetooth earphone detects button, sends the AT expanded signalling to blue tooth voice gateway request refusing to receive telephone.After blue tooth voice gateway receives the refusing to receive telephone request, refusal the other side incoming call, and can select to remove bluetooth asynchronous transmission link (s350).If the user is at blue tooth voice gateway end refusal incoming call, blue tooth voice gateway notice bluetooth earphone is so that bluetooth earphone is made corresponding processing so.
Fig. 4 explains bluetooth earphone obtain blue tooth voice gateway according to the present invention message flow diagram of air time.Earphone and blue tooth voice gateway set up link before, gateway may have been conversed a period of time with the other side.The user need forward this conversation to earphone from gateway, with bluetooth earphone and the other side's conversation.If the air time of bluetooth earphone end begins to calculate when Bluetooth link is set up, that just can not correctly reflect the real air time.Be used as fiducial time of air time so need obtain the time of having conversed from gateway.Under the situation of bluetooth asynchronous transmission link establishment, gateway and bluetooth earphone have been set up bluetooth synchronous transmission link and have been used for transferring voice (s410).Bluetooth earphone sends the time (s420) that the request of AT expanded signalling has been conversed to gateway after the synchronous transmission link is set up successfully.After gateway is received request, gateway is sent to bluetooth earphone (s430) with the time that the other side converses, if also not conversation, time span is exactly 0.Earphone as calculation of talk time fiducial time, and shows (s440) with it on liquid crystal display screen after receiving the air time.
Fig. 5 explains that bluetooth earphone obtains the message flow diagram of current time according to the present invention.The bluetooth earphone designing requirement is that volume is little, power consumption is low, so do not have the clock circuit of oneself usually.This proofreaies and correct the time of this locality with regard to often needing to obtain the current time from gateway.Set up successfully back (s510) in bluetooth asynchronous transmission link, bluetooth earphone just sends the AT expanded signalling and asks the current time (s520).After gateway is received request, just obtain the local current time and send it to bluetooth earphone (s530).Earphone is received the current time that gateway sends, and just the time of this locality is proofreaied and correct (s540).
Though the present invention illustrates and describes with reference to its preferred embodiment, but will be understood by those skilled in the art that, under the situation of the spirit and scope of the present invention that do not break away from the appended claims and limited, can carry out the various changes of situation and details.
