Infrared circuit and mobile terminal

Abstract

The invention provides an infrared circuit, a mobile terminal and a method for processing an infrared signal. The circuit comprises an interface conversion module and an infrared receiving and transmitting module, wherein the infrared receiving and transmitting module is connected with the interface conversion module, and the infrared receiving and transmitting module is used for receiving the infrared signal of the outside and converting the infrared signal into received data, or used for receiving the transmitted data sent by the interface conversion module, converting the transmitted data into the infrared signal and transmitting the converted infrared signal to the outside; the interface conversion module is used for receiving the received data sent by the infrared receiving and transmitting module and sending the data to an SIM card which is connected with the interface conversion module, or used for receiving the transmitted data sent by the SIM card and sending the transmitted data to the infrared receiving and transmitting module. The invention can realize the direct interaction of external equipment and the SIM card in a mobile phone.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal infrared circuit connected with a SIM card, a mobile terminal and a method for processing infrared signals based on the mobile terminal. Background technique [0002] The development and application of mobile communication technology are now gradually mature, and infrared applications are also more and more in mobile communication. The mobile phone with infrared function provided by the prior art, but in this technology provided by the prior art: external equipment and mobile terminals (such as The SIM card in the mobile phone) directly carries out interactive communication, needs to realize data processing and exchange through the infrared communication protocol, is more complicated, needs the function of the processor to be powerful, and the SIM card in the external device and the mobile terminal (such as: mobile phone) cannot directly for interactive c...
