Abstract
A dual-mode dual-standby mobile terminal is provided, including: dual card slots configured to interpose two communication cards; a human-machine interface adapter configured to send radio frequency starting commands to dual protocol stacks, and send, after receiving radio frequency success messages fed back by the dual protocol stacks, initialization commands to dual card management modules; the dual card management modules configured to initialize the communication cards in the dual card slots according to initialization commands sent by the human-machine interface adapter, and feed back initialization success messages to the human-machine interface adapter; dual protocol stacks configured to receive the radio frequency starting commands sent by the human-machine interface adapter, start radio frequencies in the dual protocol stacks, and feed back radio frequency state information to the human-machine interface adapter. Communication protocols are provided to the communication cards in the dual card slots according to initialization results. A communication method of the dual-mode dual-standby mobile terminal is also provided. Thus, a 2G card and a 3G card can be inserted into a …
