DUAL-MODE AND DUAL-STANDBY MOBILE TERMINAL AND DUAL-CHANNEL IMPLEMENTATION METHOD THEREOF

摘要

A dual-mode and dual-standby mobile terminal and a dual-channel implementation method thereof, and the dual-mode and dual-standby mobile terminal includes a first mode radio frequency transceiver, a second mode radio frequency transceiver, a first mode baseband chip connected to the first mode radio frequency transceiver, and a second mode baseband chip connected to the second mode radio frequency transceiver, and the mobile terminal further includes: a call processing module, which is connected to both the first mode baseband chip and the second mode baseband chip and used to perform fake call waiting processing on a call in active state in the first mode before proactively switching to a first call in a second mode when determining that there are two calls in the first mode or passively answering a second call in the second mode when determining that there are two calls in the first mode. Embodiments of the present invention implement fake call waiting by the mobile terminal switching a call device and inserting a prompt tone into an uplink network, thereby achieving the dual-mode and dual-channel of multiple calls, and the implementation method is simple and efficient.
