Bluetooth module comprises bluetooth radio, baseband controller, Bluetooth baseband protocol(BBP) firmware and link manager.Bluetooth radio is finished the eat dishes without rice or wine transmitting-receiving of data of bluetooth; Link manager is responsible for setting and the management that base band connects, and baseband controller is finished bluetooth baseband control according to the requirement of link manager.

Bluetooth module is connected to application processor system by physical interface (UART interface, USB interface etc.), and parts such as the keyboard of Man Machine Interface hardware module and display screen are connected to application processor system by physical interface (UART interface, USB interface, parallel interface, SPI interface etc.).

Fig. 3 is the system module figure of bluetooth part in blue tooth voice gateway and the Bluetooth terminal.

In Fig. 3, bluetooth radio 301 is finished the eat dishes without rice or wine transmitting-receiving of data of bluetooth; Url management protocol module 303 is responsible for each equipment room establishment of connection of bluetooth; Link manager 304 is handled information and control bluetooth baseband from bluetooth host control unit interface (HCI) transmitting layer 3 05 according to the requirement of LMP Link Manager Protocol module 303; Baseband controller 302 is finished bluetooth baseband control according to the requirement of link manager 304.

Host controller interface (HCI) transmitting layer 3 05 is optional, when the upper-layer functionality module of host controller interface transport layer when the lower floor functional module realizes in different systems, the host controller interface transport layer provides a kind of general-purpose interface of visiting the bluetooth hardware ability, the host controller interface layer protocol swap data and the order of the firmware secundum legem of the host controller interface driver 306 on the main frame and the host controller interface transmitting layer 3 05 of bluetooth equipment; When the upper layer module of host controller interface transport layer and lower module were realized in same system, order and data were transmitted by the message transfer mode in the same system, no longer need the host controller interface transport layer.

Logic link control and adapting protocol module (L2CAP) 307 are upper-layer protocol modules of base band, take upper-layer protocol by its multichannel, and burst and recombination function, service quality (QoS) and the management of bluetooth equipment group of grouping are provided.

Bluetooth service discovery protocol module (SDP) 309 is used to locate service that bluetooth equipment provides and the approach that obtains this service; Based on bluetooth binary system phone control protocol module (TCS-Binary) 308 Q.931, be used for cordless telephone standard (CTP) 311 services and intercommunication telephone standard (IntP) 310 services, comprise that call control department branch, wireless user organize administrative section and do not have the connection processing part; The standard of blue tooth voice gateway and bluetooth cellular phone applications exploiting CTP and IntP provides the voice-and-data telephone service, and the control signaling is provided by the TCS agreement, and voice are provided by baseband controller 302.

Based on the bluetooth serial ports simulation protocol module (RFCOMM) 312 of TS 07.10, can actual physics serial ports of emulation, earpiece application service (HSP) 313 and object Push Service (OPP) 314 just are to use one of standard of serial ports simulation protocol module.Earpiece application service is set up asynchronous nothing with bluetooth earphone and is connected (ACL), will set up in case of necessity synchronously towards connection (SCO), and voice transfer is arrived bluetooth earphone.The object Push Service then is used for information such as exchanging telephone basis, business card.

Further, formation is mobile/bluetooth dual-mode terminal in the mobile telephone terminal if Bluetooth terminal of the present invention is integrated into, then can with the multiplexing together application processor system of function of cellular phone, comprise MCU, RAM and FLASH chip, finish of the processing of bluetooth host control unit interface with upper-layer protocol and application; Can with the multiplexing together MMI hardware module of function of cellular phone, comprise display screen, keyboard etc., be used for the use of Bluetooth function.

Fig. 4 is the diagram that Bluetooth terminal of the present invention is realized the bluetooth earphone application function.

Bluetooth terminal equipment of the present invention is supported earpiece application standard (HSP), in the MMI of this terminal equipment module, increase control simultaneously, make this equipment the voice from Bluetooth gateway or another Bluetooth terminal can be routed to bluetooth earphone bluetooth earphone equipment.Set up a piconet between AGW or Bluetooth terminal TL2 and the TL1, carrying CTP connects on it, sets up a piconet between TL1 and the standard bluetooth earphone HS1, and carrying earphone service (HSP) connects on it.

The step that realizes this function is as follows:

Step 1: in the MMI of Bluetooth terminal TL1 module, increase configuration to bluetooth earphone equipment.Main operation has: search bluetooth earphone equipment also shows; Initiation connects the HSP of certain bluetooth earphone equipment HS1; The MMI module shows connection result 701;

Step 2: during External Call AGW, AGW is grouied busy all Bluetooth terminals that are registered on the AGW according to the TCS-Binary agreement, the calling of receiving AGW of Bluetooth terminal TL1 or another Bluetooth terminal TL2 call out TL1, after TL1 receives and calls out 702, order bluetooth earphone equipment HS1, HS1 ring 704 according to the ALERTING message " AT+RING " that the regulation of HSP sends; The user of HS1 is by answering key, and then HS1 sends and answers message " AT+CKPD " 705; Set up the SCO link between TL1 and the HS1 after TL1 receives, and the CONNECT message of transmission TCS-Binary agreement is to AGW or TL2706; AGW or TL2 receive that the CONNECT ACK message that sends the TCS-Binary agreement after the CONNECT message to TL1, sets up the SCO link 707 between TL1 and AGW or the TL2 after TL1 receives;

After step 3: TL1 receives the synchronous connection-oriented link data (being speech data) of Bluetooth gateway or TL2, at the HCI layer with this data forwarding to the synchronous connection-oriented link between TL1 and the HS1, so just will be from the voice trunking of Bluetooth gateway or TL2 to HS1 (708).

Described step 3 is specially:

31. behind the configuration bluetooth earphone, Bluetooth phone terminal device be provided with Bluetooth chip towards connecting link (SCO) data route option, be set to the SCO data are routed to the UART mouth or the USB mouth of application processor system;

32.TL1 the HCI layer of application processor system receive the SCO packet of Bluetooth gateway or TL2;

33.TL1 the HCI layer of application processor system this packet is sent to HS1, so just speech data has been routed to HS1.

In addition, step 4: if bluetooth earphone goes offline then to be attempted being connected with it automatically, concrete steps are as follows behind the configuration bluetooth earphone:

41. preserving bluetooth device address, bluetooth device name, the pairing of bluetooth earphone equipment HS1, Bluetooth phone terminal device TL1 connects information such as word;

42. Bluetooth phone terminal device TL1 detect with bluetooth earphone equipment HS1 between (ACL) link of asynchronous the connection lose synchronously;

43. Bluetooth phone terminal device TL1 is according to the automatic connection of initiating HS1 of the information of (41) step;

44., then attempt stopping from being dynamically connected HS1 behind certain number of times if can't connect HS1;

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 form and details, these changes all drop within protection scope of the present invention.
