The realization of the extension set under the mobile network, handset function provides different extension sets, the use of handset business for family or minimized office field.The restriction that the placement of such extension set, handset functional device is received is still less shifted facility more, has the place of mobile communications network just can use mobile phone extension set, handset system.Each extension set then can branch around main frame in the different room.Because the DECT phone belongs to short haul connection, about about 300 meters, so the mobility of this invention is only limited in the family or small-sized office in.
Description of drawings
Fig. 1 is the installation drawing of the embodiment of the invention;
Fig. 2 is the called realization flow figure of the inventive method embodiment.
Embodiment
The present invention aims to provide a kind of device and method that can use DECT to realize the handset function of mobile phone.Below in conjunction with Figure of description the specific embodiment of the present invention is elaborated.
Device embodiment
A kind of DECT of use as shown in Figure 1 realizes 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 come the circuit domain voice of transport communication module.
The annexation of each module is as follows in the device:
Communication module is advanced to connect with main control processor by USB (Universal Serial BUS, USB) interface; Main control processor is connected with DECT base station FP by PCM (Pulse Code Modulation, pulse-code modulation) interface and UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous reception/dispensing device); Wherein pcm interface provides passage for the transmission of PCM speech code stream, and UART provides passage for the control command to DECT.
Communication module can be communication modules such as GPRS/EDGE/UMTS/HSPA, is the carrier that the circuit domain voice are carried.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 drive by VoUSB (Voice over USB) and communicate.Described module is used for, and receives the PCM speech code stream by eating dishes without rice or wine, and transmits the PCM speech code stream to main control processor.Described VoUSB driving is that the transmission between communication module and the main control processor drives, and communication module transmits pcm stream to main control processor, and main control processor is all driven by this to communication module transmission PCM speech code stream and finishes.
Main control processor mainly plays coordinates the forwarding effect, and he is responsible for the scheduling of entire system process, the groundworks such as forwarding of PCM speech code stream.Particularly, main control processor is used for, and drives by VoUSB and receives the PCM speech code stream that is spread out of by communication module, drives by operation VoUSB2PCM (Voice overUSB to PCM) the PCM speech code stream is delivered to DECT base station FP.Described VoUSB2PCM driving is that the transmission between main control processor and the DECT base station FP drives, and main control processor transmits pcm stream to DECT base station FP, and DECT base station FP is driven by this to main control processor transmission pcm stream and finishes.
DECT base station FP is the machine tool carrier of mobile phone, comprise a microcellulor wireless communication system, be used to receive the PCM speech code stream that main control processor utilizes the UART control information to import into, and the microcellulor wireless communication system that utilizes himself, according to CAT-iq (Cordless AdvancedTechnology-internet and quality, senior wireless technology) agreement the PCM speech code stream is forwarded to hand-held set PP.
DECT hand-held set PP is an autonomous device of this system's least significant end, and it and DECT base station FP utilize the microcellulor wireless communication control system to finish ring, work such as detection.
In sum, utilize specific VoUSB2PCM driving and the holonomic system of DECT self to realize DECT phone transmission circuit domain voice in the present embodiment, and the handset function that realizes mobile phone.
Method embodiment
Present embodiment realizes that with DECT the called flow of mobile phone extension sets is an example, elaborates the main implementation method of this invention below in conjunction with accompanying drawing 3.
S202: the initialization of each module
After pressing power supply, the operating system of this device will begin 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 self initialization was finished, the GPRS/EDGE/UMTS/HSPA communication module was carried out the initialization carry as an external equipment of this system.Because this module is a USB interface, therefore also be to drive by VoUSB to load, it is to provide transmission channel for transmitting and receive pcm stream that VoUSB drives main effect.After driving loaded, communication module can be carried out the 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.System sends control signal corresponding during initialization, makes hand-held set PP can find this signal smoothly when start.
S204: after the ring of DECT handset was connected, communication module received the PCM speech code stream from the calling party by eating dishes without rice or wine.Communication module is sent pcm stream and is received control command, and this reception control command is undertaken by AT (Attention Command) order.System analysis AT order, communication module drives the PCM speech code stream at the enterprising row cache of system by VoUSB.
S206: the system at main control processor place receives data cached back and by the VoUSB2PCM driving pcm stream is sent to the PCM module.This moment, data arrived the PCM module from the USB module.
S208: by the processing of primary processor, pcm stream is sent to DECT base station FP via the PCM module, and system constructing AT order is used for sending to DECT base station FP.DECT base station FP resolves after receiving the AT order accordingly, and described parsing is finished by machine tool AT resolver, resolves the back that finishes and sets up the GAP protocol package, sends to hand-held set PP.
S210: hand-held set PP resolves after receiving the GAP protocol package, carries out corresponding playback according to analysis result then.So far the audio data stream of being brought by the calling party has been sent in the handset by this device.The calling party sets up with the handset conversation.
Processing method when the inverse process of said process is a kind of mobile phone extension sets of realizing with DECT as caller.So, repeat no more.
The above is the embodiments of the invention journey only, is not to be used to limit protection scope of the present invention, and 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 be equal to accordingly according to technical scheme of the present invention and design thereof and change or replace, and all these changes or replacement, all should belong to the protection range of claims of the present invention.
