GSM mobile handset circuit and the interface block diagram of having represented an example of PDA cordless handset phone of the present invention among Fig. 9.It mainly is made of five major parts: radio frequency part, Base-Band Processing audio-frequency unit, CPU control section, wireless communication part and power unit.Wherein, the circuit of the radio frequency part and the transceiver channel of Base-Band Processing audio-frequency unit is the same with common GSM mobile handset substantially, include audio frequency processing circuit, pcm encoder/decoding circuit, DSP circuit, GMSK modulation/demodulation circuit, intermediate frequency Modulation/demodulator circuit, receipts/Power Generation Road and antenna circuit, but the present invention has increased the voice channel control circuit between audio frequency processing circuit and pcm encoder/decoding circuit; At the CPU control section, the present invention also is the same with common GSM mobile handset substantially, but has increased PC computer interface circuit and audio record circuit; The wireless communication part then is that common GSM mobile handset is unexistent.

Compare PDA cordless handset and common GSM mobile handset among the present invention:

1. interface and the corresponding interface circuits that the former is equipped with directly and the PC computer carries out communication, thus its directly Uninstaller, picture and text, sound material and data from the PC computer, and the latter can not.

2. the former is equipped with audio record circuit (it can be traditional high sampling rate, the playback circuitry of high tone quality, also can be other popular playback circuitry such as MP3 one class), so it has recording playback, the offloading functions of language, music, and the latter can not.

3. the former has increased the voice channel control circuit in the voice signal treatment circuit, make mobile phone speaker and mobile phone Mike except conversing with the external world, can also directly link to each other by the voice signal treatment circuit (certainly with audio record circuit, also can increase a pair of loud speaker, Mike in addition, and respective handling circuit), independently record and play language or music, and the latter can not.

4. the former has increased the wireless communication part, make mode that mobile phone can be by wireless connections and base between transmit voice signal or data information, and the latter can not.

For exempting from push-to-talk handset, pcm encoder/decoding circuit among Fig. 9 and DSP circuit all can omit.CPU directly carries out the transmitting-receiving of literal, figure or audio files data through GMSK circuit, intermediate frequency Modulation/demodulator circuit, receipts/Power Generation Road and antenna circuit.

For multichannel cordless handset phone, the configurable many estrades machine of main frame.Can contain one even many PDA mobile phones in these handsets.They all can realize the repertoire of above-mentioned PDA palmtop PC and regular handset, and do not belong to other handset of PDA mobile phone, the repertoire that still has common cordless telephone handset.

Base circuit and the interface block diagram of having represented an example of PDA cordless handset phone of the present invention among Figure 10.The same with the main frame of common cordless telephone, the main frame of PDA cordless handset phone has CPU, receiving circuit, radiating circuit, phase lock circuitry, duplexer and antenna circuit, keyboard and ringing circuit, speech processing circuit etc. equally, but the latter also is equipped with the data communication adapter circuit with the external network exchange data information---modulation-demodulation circuit Modem, and the outside line channel control circuit.When mobile phone need be when external network receives data, by to the host CPU application, cut off getting in touch of voice signal treatment circuit and local telephone network interface circuit by host CPU by the outside line channel control circuit, start modulation-demodulation circuit Modem operation, to send to the PDA mobile phone by radiating circuit from the data message that outside line receives simultaneously, give mobile phone CPU through the receiving circuit in the PDA mobile phone again, store at last to the EEPROM/FLASH circuit.Perhaps, be deposited at earlier in the data memory in the main frame, send to the PDA mobile phone after a while more in batch.Equally, when the PDA mobile phone need be when external network sends data, the data that then will send send to host CPU through the radiating circuit of PDA mobile phone and the receiving circuit of main frame earlier, send to outside line through modulation-demodulation circuit Modem again.Perhaps, be deposited at earlier in the data memory in the main frame, send to outside line after a while more in batch.

For the Telephone set that adopts the DLC access way, owing to what fail in the terminal phone line itself is exactly digital signal, therefore, can be without modulation-demodulation device by other adapter circuit of network termination apparatus NT regulation, swap data between PDA handset and network termination apparatus.

In addition, although in some common cordless telephone main frame loud speaker and Mike are installed also, they only are used for the hand-free call function; And in PDA cordless telephone main frame shown in Figure 3, though loud speaker and Mike are installed equally, but they both can use for the hand-free circuit in the main frame under the control of CPU and voice channel control circuit, and the audio record circuit that can offer again in the PDA mobile phone uses.For example, when the user operates the PDA cordless telephone, when choosing re-reading English data, following process promptly brings into operation:

1.PDA mobile phone CPU finds the start address of re-reading data from EPROM/EEPROM/FLASH, wherein written historical materials send the dot lcd screen to show that audio files (is a voice address to some audio record circuit) is the sending voice playback circuitry then.

2.PDA mobile phone CPU sends the request that plays sound by the handset radiating circuit to main frame.

3. after host CPU is received request by master machine antenna and receiving circuit,,, open the passage of voice signal treatment circuit and main frame loud speaker then by the voice channel control circuit if detect main frame not in conversation to outside line.Simultaneously, notice PDA mobile phone CPU can play.Otherwise notice PDA mobile phone CPU suspends broadcast.

After 4.PDA mobile phone CPU receives the answer of agreeing to play by master machine antenna and receiving circuit, promptly close voice signal treatment circuit and mobile phone Mike's passage by the mobile phone speech channel control circuit, and open the passage of voice signal treatment circuit and audio record circuit, and order audio record circuit playback.

5. re-reading data recording is by mobile phone radiating circuit and main frame receiving circuit, and main frame voice signal treatment circuit, comes out in the main frame loudspeaker plays.

In above-mentioned the 4th step, if the PDA mobile phone can't be received the answer of host CPU, PDA mobile phone and main frame are in non-coupled situation in other words, then PDA mobile phone CPU passes through the passage of mobile phone speech channel control circuit opening voice signal processing circuit and mobile phone speaker, and order audio record circuit playback.This that is to say that the PDA mobile phone can be under the situation away from main frame, independent operating, and re-reading data is play by mobile phone speaker.This in fact also is to provide a portable language repeater for the user.

Also have a difference with common wireless base, the clipboard circuit is installed in the base of the present invention.Utilize mode identification technology, can make the user by writing input characters and figure easily.

If connect by the way of contact between PDA mobile phone and the Telephone set, it is the regular handset phone (the rope mobile portable phone is arranged) among the present invention, so, as long as excision wireless communication part in the circuit of Fig. 9, and some other control circuit, and in Figure 10, remove antenna circuit, reception and radiating circuit and get final product, but must increase corresponding mobile phone guide card and base stage clip.As Fig. 5, shown in Figure 6.Both link by one group of mobile phone guide card and base stage clip.Wherein except a pair of guide card was used for the cellular phone power supplies charging, all the other were mainly used in data transmission channel and voice transfer passage.When between mobile phone CPU and base CPU during, need take a pair of guide card by serial mode transmission data.And the input of voice need take a pair of guide card with output.So generally need the combination of three pairs of guide cards and stage clip.

As required, can lay on the pedestal machine one or several specifications different with interface handset.

Utilize the present invention, can also make up and generate the words communication of a plurality of fairgrounds, Personal Handyphone System(PHS) communication, mobile communication advantage separately, and the PDA function is in the series of products of one.
