The mobile communication terminal of the present invention comprises a first RF part for executing the signal processing, using a first wireless frequency band, required by a first wireless communication; a second RF part for executing the signal processing, using a second wireless frequency band, required by Global System for Mobile Communications(GSM); a memory for storing each time slot information set for the first wireless communication and GSM communication; a control part for setting the time slot information for Mobile Communications(GSM)and the first wireless communication, and distributing the receiving and transmitting time slot of the first wireless communication to the time slot that is not arranged to be transmitting time slot of the GSM communication, and executing the communication. When the GSM communication module and the first wireless communication module are realized synchronously in one mobile communication terminal, the time slot of the first wireless communication is distributed keeping away from the transmitting time slot of the GSM communication so as to prevent the wave interference caused by the increasing of the transmitting power of the transmitting time slot of the GSM communication. Thus, even if the GSM communication module and the first wireless communication module are present in one mobile communication terminal, the communications of the two modules will not affect with each other, and each of the two modules can providing optimal communication environment respectively. |
