1. A dual-mode and dual-standby mobile terminal, comprising 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, wherein the mobile terminal further comprises:
a call processing module, connected to both the first mode baseband chip and the second mode baseband chip, and configured to perform fake call waiting processing on a call in active state in a 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 before passively answering a second call in the second mode when determining that there are two calls in the first mode, wherein the call processing module is configured to perform fake call waiting processing on the call in active state in the first mode, by being configured to shield a call device of the call in active state in the first mode, and insert a prompt tone in an uplink, wherein a time length of playing the prompt tone is controlled by a timer, after the timer expires, playing the prompt tone is stopped. |
