Problems solved by technology

[0002] Existing dual-channel mobile terminals generally have two sets of radio frequency circuits, and the existing radio frequency calibration method usually uses one set of radio frequency circuits to be calibrated before restarting and reset; and then the other set of radio frequency circuits is calibrated and then The radio frequency calibration operation is performed by restarting and resetting, that is, two restarting and resetting operations are required during the calibration process, so the operation is cumbersome and the calibration efficiency is not high. The key problem is that in the radio frequency calibration process, the existing technology cannot The radio frequency calibration of the two sets of radio frequency circuits is completed on the premise that the mobile terminal is in the power-on state, that is, the prior art does not realize the flexible switching of the communication channels between the radio frequency calibration equipment (such as the radio frequency comprehensive tester CMU200) and the two sets of radio frequency circuits respectively

Abstract

The invention discloses a two-channel mobile terminal, which comprises a first processor and a first radio frequency circuit, a second processor and a second radio frequency circuit, a USB socket and a USB port multiplexing device; a USB communication channel between the first radio frequency circuit and a peripheral device connected to the USB socket is established via the USB port multiplexing device; and a USB communication channel between the first processor and the second radio frequency circuit is established via the USB port multiplexing device. The invention further provides a radio-frequency calibration system of the two-channel mobile terminal. According to the two-channel mobile terminal and the radio-frequency calibration system disclosed by the invention, multiple USB communication channels can be established via one USB port on the mobile terminal; and thus, the multiplexing of the USB port of the two-channel mobile terminal and the flexible switching of the USB communication channels are realized; and while the utilization rate of the USB port is improved, the calibration operating process of the two-channel mobile terminal is simplified.
