Accompanying drawing explanation
Fig. 1 is the installation drawing of the embodiment of the present invention;
Fig. 2 is the called realization flow figure of the inventive method embodiment.
Embodiment
The present invention aims to provide a kind of DECT that can use to realize the device and method of the handset function of mobile phone.Below in conjunction with Figure of description, the specific embodiment of the present invention is described in detail.
Device embodiment
A kind of DECT of use as shown in Figure 1, to realize the device of the handset function of mobile phone, comprising: communication module, main control processor, DECT base station FP (Fixed Part) and DECT hand-held set PP (Portable Part).The use (SuSE) Linux OS of this device, and can directly utilize the USB transmission mechanism of (SuSE) Linux OS itself to carry out the circuit domain voice of transport communication module.
In device, the annexation of each module is as follows:
Communication module is entered to connect with main control processor by USB (Universal Serial BUS, USB) interface; Main control processor is by PCM (Pulse Code Modulation, pulse-code modulation) interface and UART (Universal Asynchronous Receiver/Transmitter, Universal Asynchronous Receive/dispensing device) be connected with DECT base station FP; Wherein pcm interface provides passage for the transmission of PCM speech code stream, and UART is then for providing passage to the control command of DECT.
Communication module can be the communication modules such as GPRS/EDGE/UMTS/HSPA, is the carrier of circuit domain voice conveying.Described module is connected with main control processor by USB interface on hardware, and from the angle of software, communication module and main control processor are driven by VoUSB (Voice over USB) and communicate.Described module is used for, and receives PCM speech code stream, and transmit PCM speech code stream to main control processor by eating dishes without rice or wine.Described VoUSB driving is that the transmission between communication module and main control processor drives, and communication module transmits pcm stream to main control processor, and main control processor sends PCM speech code stream to communication module all have been come by this driving.
Main control processor mainly plays coordinates forwarding effect, the groundworks such as he is responsible for the scheduling of entire system process, the forwarding of PCM speech code stream.Particularly, main control processor is used for, and is driven the PCM speech code stream receiving and spread out of by communication module by VoUSB, then by running VoUSB2PCM (Voice over USB to PCM) driving, PCM speech code stream is delivered to DECT base station FP.Described VoUSB2PCM driving is that the transmission between main control processor and DECT base station FP drives, and main control processor transmits pcm stream to DECT base station FP, and DECT base station FP sends pcm stream to main control processor all have been come by this driving.
DECT base station FP is the machine tool carrier of mobile phone, comprise a microcellular radio communication system, for receiving the PCM speech code stream that main control processor utilizes UART control information to import into, and utilize the microcellular radio communication system of himself, according to CAT-iq (Cordless Advanced Technology-internet and quality, senior wireless technology) agreement, PCM speech code stream is forwarded to hand-held set PP.
DECT hand-held set PP is an autonomous device of this system least significant end, and it and DECT base station FP utilize microcellular radio communication control system to complete ring, the work such as detection.
In sum, utilize the holonomic system of specific VoUSB2PCM driving and DECT self to realize DECT phone transmission circuit territory voice in the present embodiment, and realize the handset function of mobile phone.
Embodiment of the method
The present embodiment realizes the called flow of mobile phone extension sets for DECT, elaborates the main implementation method of this invention below in conjunction with accompanying drawing 2.
S202: the initialization of modules
After pressing power supply, the operating system of this device will start to load, and carries out the initial work of various peripheral components, wherein the most important thing is the initialization of the FP of communication module and DECT base station.
After system initializes itself completes, GPRS/EDGE/UMTS/HSPA communication module carries out initialization carry as an external equipment of this system.Because this module is USB interface, be therefore also driven by VoUSB to load, VoUSB drives Main Function to be provide transmission channel for transmitting and receive pcm stream.After drive load, communication module can carry out reception and the transmission of PCM speech code stream normally.
By serial ports and PCM mouth, DECT base station FP is loaded during system initialization.During initialization, system sends corresponding control signal, makes hand-held set PP can find this signal smoothly when starting shooting.
S204: after the ring of DECT handset is connected, communication module receives the PCM speech code stream from calling party by eating dishes without rice or wine.Communication module sends pcm stream and receives control command, and this reception control command is undertaken by AT (Attention Command) order.System analysis AT order, communication module is driven PCM speech code stream at the enterprising row cache of system by VoUSB.
S206: the system acceptance at main control processor place is sent to PCM module by VoUSB2PCM driving pcm stream after data cached.Now data reach PCM module from USB module.
S208: by the process of primary processor, pcm stream is sent to DECT base station FP via PCM module, system constructing AT order, for sending to DECT base station FP.Resolve accordingly after DECT base station FP receives AT order, described parsing is completed by machine tool AT resolver, sets up GAP protocol package after parsing, sends to hand-held set PP.
S210: hand-held set PP resolves after receiving GAP protocol package, then carries out corresponding playback according to analysis result.So far the speech data brought by calling party flows through this device and has been sent in handset.Calling party sets up with handset call.
The inverse process of said process is the mobile phone extension sets of a kind of DECT realization as processing method during caller.So, repeat no more.
The foregoing is only embodiments of the invention journey, not for limiting the scope of the invention, the present invention is equally applicable to other wireless network can comprise TD-SCDMA, WCDMA, CDMA2000, HSDPA etc.Simultaneously; concerning the those of ordinary skill in field, the technology of the present invention place; can carry out corresponding equivalent change according to technical scheme of the present invention and design thereof or replace, and all these change or replace, and all should belong to the protection range of claims of the present invention.
