[embodiment]
Below in conjunction with accompanying drawing technology of the present invention is described in detail.
Please refer to Fig. 2.This figure is the system construction drawing of intelligent mobile phone of the present invention.This intelligent mobile phone 20 comprises application processor 22, Communication processor 24, Bluetooth chip 30, wherein, application processor 22 is connected with Communication processor 24 by serial ports 2, application processor 22 is connected with Bluetooth chip 30 by serial ports 1, and Bluetooth chip 30 is controlled transmission with data.Application processor 22 also is connected with Bluetooth chip 30 by USB, adopts serial ports to connect in the present embodiment and describes.Communication processor 24 is connected with Bluetooth chip 30 by pcm interface, the voice transfer of control Bluetooth chip 30.
Aspect the software realization, application processor 22 is by serial ports 2 control Communication processors 24, by serial ports 1 and Bluetooth chip 30, wherein, interface between application processor 22 and the Communication processor 24 is the AT order, and control Communication processor 24 is realized functions such as conversation, wireless Internet access; Interface between application processor 22 and the Bluetooth chip 30 can be AT order or HCI agreement, and control Bluetooth chip 30 is sought functions such as other bluetooth equipment, pairing, link setup.Pcm interface only is used at when conversation transmitting audio data between Communication processor 24 and the Bluetooth chip 30.
1, voice transfer
Please refer to Fig. 3.When needs were set up the bluetooth call mode, application processor 22 was set up being connected of Bluetooth chip and bluetooth earphone by serial ports 1 control; Application processor 22 is ordered the pcm interface of opening Communication processor 24 and Bluetooth chip 30 by AT, and speech data is switched to the PCM passage, and speech data is just with the pcm interface output of pcm encoder mode from Communication processor 24 like this; Application processor 22 is opened the PCM passage of Bluetooth chip 30 by serial ports 1 control; Application processor 22 is controlled Communication processor 24 by serial ports 2 and is come number dialing telephone call or connecting incoming call.Like this, just set up the bluetooth call mode of mobile phone.Like this, when needs are conversed by bluetooth earphone, application processor 22 is opened the pcm interface of Communication processor 24 and Bluetooth chip 30 by the AT order, speech data is just with the pcm interface output of pcm encoder mode from Communication processor 24, simultaneously from the speech data of pcm interface reception from Bluetooth chip 30 like this.Adopt the communication process of just finishing bluetooth mode in such a way.
When not using bluetooth earphone to converse, application processor 22 is controlled the PCM passage of closing Bluetooth chip 30 by serial ports 1, closes the bluetooth call mode of mobile phone.At this moment, application processor 22 switches to SPEAKR/MIC by serial ports 2 control Communication processor 24 with speech data.Like this, speech data is handled the back by SPEAKER output through the communication module DSP of Communication processor 24, and the DSP that gives the communication module of Communication processor 24 by the MIC input again handles.Adopt and just finish general normal talking process in such a way.
2, transfer of data
When mobile phone need carry out transfer of data with other bluetooth equipment, application processor 22 control Bluetooth chips 30 according to Bluetooth protocol match successively, step such as link setup, carry out transfer of data by the serial ports between application processor 22 and the Bluetooth chip 30 1 then.In the present embodiment, will carry out transfer of data between the bluetooth equipment according to the HCI agreement.
HCI transmits data, order and incident by the mode of wrapping, and all communications between application processor 22 and Bluetooth chip 30 are all carried out with the form of bag.The return parameters that comprises each order all transmits by specific incident bag.HCI has data, order and three kinds of bags of incident, and wherein packet is two-way, and order bag can only mail to Bluetooth chip 30 from application processor 22, and the incident bag to be Bluetooth chip 30 all the time be sent to application processor 22.Most of order bags that application processor 22 sends all can trigger Bluetooth chip 30 and produce the events corresponding bag in response.Wherein:
The order bag is divided into six types:
1) controlling links order;
2) link policy and mode command;
3) host computer control and base band order;
4) message command;
5) status command;
6) test command.
The incident bag also can be divided into three types:
1) general purpose event comprises that order finishes bag (Command Complete) and coomand mode bag (Command Status);
2) test event;
Event when 3) makeing mistakes is lost (Flush Occured) and (Data Buffer Overflow) overflowed in the data buffer zone as generation.
Packet then can be divided into the packet of ACL and SCO.The form of HCI bag as shown in Figure 4.
When between application processor 22 and the base band with the mode of order when communicating, application processor 22 sends the order bag to Bluetooth chip 30.Bluetooth chip 30 is finished an order, and in most cases, it can send an order to application processor 22 and finish incident bag (Command CompletePacket), carries the information that order is finished in the bag.Some order can not receive orders and finish incident, and the state event bag that can receive orders (Command Status Packet), handle when receiving that order that this incident represents that then application processor 22 sends has been received by Bluetooth chip 30 and begun, this order after a while is performed when finishing, and Bluetooth chip 30 can send the events corresponding bag to application processor 22 and notify application processor 22.If command parameter is wrong, then can in command status event, provide corresponding error code.If wrong appearing in the order of returning Command Complete incident bag, then this Command Complete incident bag not necessarily contains defined all parameters of this order.State parameter also is first parameter of returning as the misconstruction reason simultaneously, always will return.If following state parameter closely is afterwards the device address that connects handle or bluetooth, then this parameter also always will be returned, and can determine the order that this Command Complete incident bag belongs to that example like this.In this case, the device address of connection handle or bluetooth should be consistent with the relevant parameter that the order bag is planted in the incident bag.If wrong appearing in the order of not returning Command Complete incident bag, then all parameters of comprising of incident bag are all not necessarily effective.Application processor 22 must be pursuant to state parameter in the incident bag that this order interrelates and decide their validity.
The above only is a preferred example of the present invention, and in order to restriction the present invention, within the spirit and principles in the present invention not all, institute changes, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
