Embodiment Construction

[0026] The present invention aims to provide a device and method capable of using DECT to realize the function of a mobile phone as a slave. The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Device embodiment

[0028] Such as figure 1 A device that uses DECT to implement the mobile phone's slave function includes: a communication module, a main control processor, a DECT base station FP (Fixed Part) and a DECT handset PP (Portable Part). The device uses a Linux operating system, and can directly use the USB transmission mechanism of the Linux operating system itself to transmit the circuit domain voice of the communication module.

[0029] The connection relationship of each module in the device is as follows:

[0030] The communication module is connected with the main control processor through the USB (Universal Serial BUS, universal serial bus) interface; The receiving / se...

Abstract

The invention discloses a device and a method for realizing functions of an extension telephone set of a mobile phone by using DECT (Digital Enhanced Cordless Telecommunications). The device comprises a communication module, a main control processor, a DECT base station FP and a handset, and is characterized in that the communication module is connected with the main control processor through a USB interface, and the main control processor is connected with an FP through a pulse code modulation (PCM) serial port and a universal asynchronous receiver / transmitter (UART). The method is characterized in that the communication module exchanges data with a mobile communication network through an idle port, the main control processor ensures that the data exchange is realized between the communication module and the DECT base station FP, and data exchange is carried out between the base station FP and the handset. The device can be well applied to families and small official places and realizes the functions of the extension telephone set and a sub telephone of the mobile phone.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a device and method for realizing mobile phone extension function by using DECT Background technique [0002] DECT (Digital Enhanced Cordless Telecommunications Digital Enhanced Cordless Communications) is a cordless telephone standard that integrates data applications. DECT relies on a diversity channel allocation program, which is called DCS (Dynamic Channel Selection). The portable terminal does not have a fixed channel, but constantly scans the available channels to find the best channel. The channels used by DECT portable terminals are screened from 120 existing channels. Pick the one with the least interference, and of course the channel list will be updated regularly. DECT is mainly used for short-distance communication. At present, it is mainly combined with PSTN (Public Switched Telephone Network) for voice applications of cordless phones for fixed-line us...
