Short distance communication device and method for portable terminal

Abstract

The present invention relates to a mobile communication terminal for short-distance communication, which includes a mobile communication wireless unit, a control unit, a handset sending unit, and a microphone receiving unit, wherein the control unit judges whether to connect to the mobile communication wireless unit for mobile communication, or The allocated frequency is for short-distance communication, so as to control and monitor the above-mentioned process accordingly; the above-mentioned handset sending part outputs mobile communication voice signals through the control of the control part, and wirelessly sends short-distance communication signals at a certain frequency; the above-mentioned microphone receiving part The mobile communication voice signal is input through the control of the control unit, and the short-distance communication signal is wirelessly received at a certain frequency. In addition, the present invention also provides a short-distance communication method corresponding to the above-mentioned device. Because the receiver and microphone are shared with mobile communication, and another certain wireless frequency is used instead of infrared rays for communication, it has the advantages of saving manufacturing costs and reducing volume. , making the appearance design more beautiful.

Description

technical field [0001] The present invention relates to a portable terminal and a short-distance communication method thereof, in particular, a mobile communication earpiece is additionally provided with a wireless transmitter for short-distance communication, and the above-mentioned mobile communication microphone is additionally provided with a short-distance communication The wireless receiving unit is a short-distance communication device for a portable terminal that performs short-distance communication with an additionally allocated wireless frequency, and a method thereof. Background technique [0002] The mobile communication portable terminal (UE: USER EQUIPMENT) is free to move within the service area (SERVICE AREA) formed by the corresponding base station (RAN: RADIO ACCESS NETWORK) of the registered system, and passes through the mobile switching center (MSC: MOBILE SWITCHING CENTER ) monitoring, control and switching (SWITCHING) communication channel formed by a...

AI Technical Summary

Problems solved by technology

[0019] Since mobile communication and infrared communication require separate earpieces and microphones, there is a problem of increased manufacturing costs for portable terminals.

[0020] In addition, since the earpiece and the microphone are separately provided, the size of the portable terminal is increased, and it is difficult to realize miniaturization, which has the problem of restricting the beautification of the appearance design.
