Mobile phone and the method for signal processing thereof

Abstract

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 distributed with 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 electric 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 provide optimal communication environment respectively.

Description

technical field [0001] The present invention relates to the signal processing of the mobile communication terminal, especially when realizing the wireless communication using the GSM (Global System for Mobile communication) communication module and other TDMA (Time division multiple access: time division multiple access) modes in a mobile communication terminal module, the signal processing is performed in the mobile communication terminal. Background technique [0002] GSM is a digital mobile phone system widely used in Europe and elsewhere. GSM is a variant of TDMA, and it has become one of the three widely used digital wireless phone technologies together with TDMA and CDMA. [0003] GSM digitizes and compresses the data, then sends it over a channel along with two other user data, each in its own inherent time slot. GSM can operate in both 900MHz and 1800MHz frequency bands. [0004] GSM is the de facto standard for wireless telephony in Europe. GSM has more than 120...

AI Technical Summary

Problems solved by technology

[0009] Therefore, in the time slot set by the Bluetooth module, in the part overlapping with the GSM transmission time slot, it is greatly affected by the GSM transmission power, and there is a problem that the Bluetooth communication service quality is degraded.
