Abstract

A dual modem device is provided. The dual modem device includes a first processor for communicating with a first network and a second processor for communicating with a second network and the second processor includes a host module for controlling the first processor. The first processor includes a first processor side IPC (Inter-Processor Communication) for transceiving signals with the second processor and the second processor further includes a second processor side IPC for transceiving signals with the first processor. The second processor transfers a suspend message to the first processor for shifting to a suspend mode and configures the second processor side IPC to not work. The first processor receives the operating suspend message, transfers a suspend response message to the second processor and configures the first processor side IPC to not work.
