The invention discloses a transmitting power control system and method and a mobile communication terminal and belongs to the technical field of a communication system. The system comprises an information acquisition unit, a judgment unit connected with the information acquisition unit, and an adjustment unit connected with the judgment unit. The method comprises the following steps: obtaining communication information of the mobile communication terminal working under an LTE communication system; judging the communication information to determine whether to output working time period information of the mobile communication terminal working under the LTE communication system; if not, giving no treatment; judging whether transmitting time period when the mobile communication terminal transmits signals under a GSM communication system is included in the working time period information; if not, giving no treatment; and lowering the transmitting power, at which the mobile communication terminal transmits signals under the GSM communication system correspondingly, and then, quitting. The beneficial effects of the technical scheme are that communication quality is improved, a complex circuit structure is not needed, and the cost is reduced.
Description
technical field [0001] The present invention relates to the technical field of communication systems, in particular to a transmission power control system and method and a mobile communication terminal. Background technique [0002] The existing mobile communication terminal can support simultaneous operation under the LTE communication system (Long Term Evolution, long term evolution) and the GSM communication system (Global System for Mobile Communication, global system for mobile communication). However, working under the two communication systems at the same time will cause blocking interference and spurious interference between the antennas of the radio frequency modules inside the mobile communication terminal, which will cause the receiver of the mobile communication terminal to fail to receive communication signals normally, resulting in mobile communication terminal communication quality is degraded. Contents of the invention [0003] According to the problems ex...
