MOBILE TERMINAL SYSTEM SUPPORTING NARROWBAND AND WIDEBAND DUAL-MODE CONVERGENCE

摘要

The present invention is applicable to the technical field of communications and provides a mobile terminal system supporting narrowband and wideband dual-mode convergence, comprising a narrowband communications module and a power management chip. The mobile terminal system further comprises a main control chip having a 3G communications function and a 4G communications module. The main control chip is separately connected to the narrowband communications module, the 4G communications module, and the power management chip, and is configured to send and receive control instructions. The power management chip is separately connected to the 4G communications module and the narrowband communications module. The mobile terminal system can provide high-definition and high-quality voice, image, and video trunking communications capability by means of narrowband and wideband dual-mode convergence.
