Abstract

A Bluetooth GSM dual-mode cordless telephone comprises a human-machine interface unit, a processor, a Bluetooth modular, a GSM modular, a receiver/speaker, a Bluetooth antenna and a GSM antenna; wherein, the human-machine interface unit is connected with the processor through an I/O interface; the processor is separately connected with the Bluetooth modular and the GSM modular through a serial port and is separately connected with the receiver/speaker through a controlling interface; the Bluetooth antenna and the GSM antenna are connected with the Bluetooth modular and the GSM modular through a radio-frequency interface; the receiver/speaker is connected with the Bluetooth modular and the GSM modular through an analog voice interface and completes the switch from the analog voice signal to the Bluetooth modular or the GSM modular according to the command order of the processor. The utility model can provide a cordless telephone solution having much lower cost with the Bluetooth technology. Meanwhile, the utility model can use the GSM mobile communication function at the place where has no Bluetooth network signal coverage and when telephone is roaming.

Description

Bluetooth GSM dual-mode wireless phone

Technical field

The utility model relates to Bluetooth technology and the GSM technology in the wireless communication field.Be specially a kind of dual-mode wireless phone of in local fixed-line telephone network or GSM net, realizing mobile communication.

Background technology

Personal Handyphone System replenishes and extends as local telephone system, makes full use of the idle Internet resources of landline telephone, and because of characteristics such as its one-way charge, telephone expenses be cheap receive telephone subscriber's favor greatly, fast development in recent years becomes the new business growth point of telecommunication department.Yet present developing from pas network also has a lot of blind areas, can not roam as mobile phone, and what take is the 3G frequency range that in order to develop 3G, country will clear up the relevant resource of frequency range of 3G, the row of the frequency range that Personal Handyphone System is being cleared up.

In the prior art, exist a kind of short-distance wireless communication technology that is called as bluetooth (Bluetooth), it is operated in ISM (industry, science, the medical treatment) frequency range of 2.4GHz.Have that cost is low, good confidentiality, transmission rate advantages of higher.The piconet (Piconet) that the basic network topology of bluetooth is made up of a main control device and maximum seven slaves adopts the mode of time division multiple access (TDMA) to communicate between main control device and the slave.Utilize Bluetooth technology, can various device be coupled together in low-cost mode.Therefore can replace present Personal Handyphone System with Bluetooth technology fully, provide cost lower Personal Handyphone System(PHS) solution.In order to solve the problem of blind area and roaming, also built-in gsm module can use the GSM mobile communication function in this dual-mode wireless phone when area that does not have blue teeth wireless telephone network signal to cover and roaming.

Summary of the invention

The purpose of this utility model is to provide a kind of bluetooth GSM dual-mode wireless phone of realizing mobile communication in local fixed-line telephone network and GSM network.

The utility model is realized by the following technical solutions, be a kind of bluetooth GSM dual-mode wireless phone of in local fixed-line telephone network and GSM network, realizing mobile communication, comprise: human and machine interface unit, processor, bluetooth module, gsm module, receiver/loud speaker, Bluetooth antenna and GSM antenna; Wherein human and machine interface unit is connected with processor by the I/O interface; Processor links to each other with gsm module with bluetooth module respectively by serial ports, and links to each other with receiver/loud speaker by control interface; Bluetooth antenna is not connected with gsm module with bluetooth module by radio frequency interface with branch GSM antenna; Receiver/loud speaker links to each other with bluetooth module, gsm module by the simulated voice interface respectively, and finishes the switching of analog voice signal to bluetooth module or gsm module according to the instruction of processor.

The technique effect that the utility model produces owing to described structure is conspicuous, promptly utilizes Bluetooth technology, can various device be coupled together in low-cost mode.Therefore can replace present Personal Handyphone System with Bluetooth technology fully, provide cost lower Personal Handyphone System(PHS) solution.Simultaneously, also built-in gsm module in this dual-mode wireless phone can use the GSM mobile communication function when area that does not have blue teeth wireless telephone network signal to cover and roaming.
