Abstract
The invention relates to the field of industrial automation, in particular to a PHS/GSM dual-mode mobile phone system based on a PHS mobile station, which can well solve the problem of fusion of two nets and lead a user to be capable of not only enjoying low price of a PHS network, but also fully utilizing the advantages of GSM network coverage. The PHS/GSM dual-mode mobile phone system comprises: a radio frequency part and a baseband part, wherein the PHS mobile station and a GSM module of the radio frequency part are respectively provided with a set of independent letter receiving and transmitting unit and an antenna system; and a BBIC of the PHS mobile station of the baseband part is used as a main control unit to carry out communication by a UART port and the GSM module.
Description
Technical field:
The present invention relates to the industrial automation field, especially relates to a kind of PHS/GSM two-mode mobile phone system based on the PHS travelling carriage.
Background technology:
At present, 2G system and wireless local telephone system PHS are incompatible, and the user of heterogeneous networks wants to realize internetwork roaming, must use different mobile phone terminals, have limited the development of mobile communications network to a large extent.
Summary of the invention:
The present invention is exactly genuine the problems referred to above, and a kind of warm problem of two nets that solves well is provided, and makes the user can either enjoy the low price of PHS network, can make full use of the advantage of the GSM network coverage again.
The present invention adopts following technical scheme: a kind of PHS/GSM two-mode mobile phone system based on the PHS travelling carriage, and it comprises: radio frequency part, baseband portion; Described radio frequency part PHS travelling carriage and gsm module have separately and overlap independently transceiver unit and antenna system; Described baseband portion, the BBIC of PHS travelling carriage communicates by UART mouth and gsm module as main control unit.
As preferred version one, adopt double antenna on the radio frequency part Terminal Design of the present invention, the aerial signal of different system is through entering receiver unit after the antenna reception separately, after a series of processing such as filtering, amplification, mixing, demodulation, deliver baseband portion and do further channel decoding processing.
As preferred version two, radio frequency part of the present invention is when transmitting, and the I that sends from baseband portion, Q orthogonal simulation signal are launched modulated carrier by antenna after modulation, filtering, power amplification etc. are handled.
As preferred version three, the shared man-machine interface partial circuit of the PHS travelling carriage of baseband portion of the present invention and gsm module is as LCD, keyboard etc.
The present invention includes the relevant design of hardware and software of PHS/GSM two-mode mobile phone system of PHS travelling carriage, solve the warm problem of two nets well, make the user can either enjoy the low price of PHS network, can make full use of the advantage of the GSM network coverage again.
Beneficial effect:
The present invention is owing to adopted the PHS travelling carriage as main control part, and gsm module is the subordinate part, can solve the warm problem of two nets well, makes the user can either enjoy the low price of PHS network, can make full use of the advantage of the GSM network coverage again.

Fig. 2 is a software systems block diagram of the present invention.
Embodiment:
A kind of PHS/GSM two-mode mobile phone system based on the PHS travelling carriage, it comprises: radio frequency part, baseband portion; Described radio frequency part PHS travelling carriage and gsm module have separately and overlap independently transceiver unit and antenna system; Described baseband portion, the BBIC of PHS travelling carriage communicates by UART mouth and gsm module as main control unit.
Radio frequency part
PHS travelling carriage and gsm module have separately and overlap independently transceiver unit and antenna system.In view of the PHS system is different with the frequency range that GSM uses, adopt double antenna on the Terminal Design, need mate respectively, can consider that built-in aerial adds the form of external antenna.During received signal, the aerial signal of different system, is delivered baseband portion and is done further channel decoding processing after a series of processing such as filtering, amplification, mixing, demodulation through entering receiver unit after the antenna reception separately.When transmitting, the I that sends from baseband portion, Q orthogonal simulation signal are launched modulated carrier by antenna after modulation, filtering, power amplification etc. are handled.
Baseband portion
The BBIC of PHS travelling carriage communicates by UART mouth and gsm module as main control unit.The shared man-machine interface partial circuit of PHS travelling carriage and gsm module is as LCD, keyboard etc.Both sharing audio partial circuits are finished the switching of different communication systems by analog switch, make voicefrequency circuit offer the system of conversation demand all the time.The subscriber data of PHS is stored in the EEPROM of its mainboard, and the subscriber data of GSM is then provided by SIM card.Battery adopts lithium battery.
During start, hardware reset signal at first wakes the PHS travelling carriage up, after the PHS travelling carriage enters steady-working state, sends start and reset signal to gsm module, wakes the gsm module part up.Shutdown process then in contrast.
The software general frame
The task of interface section is partly carried out by the PHS travelling carriage, finishes electrification reset processing, caller/called flow processing, short message flow processing, telephone directory and the log processing etc. of gsm module.The MMI part also is responsible for gsm module man-machine interface shared with it by the PHS travelling carriage.Carry out communication by AT order between PHS travelling carriage and the gsm module.
