| 摘要 |
The present invention provides a dual mode mobile device that can use both cellular-based and IP-based applications with single application program interface and without having separate and distinct subsystems for each communications mode. The device may also include a power management module that considerably reduces the power consumption of the device by periodically entering a deep sleep mode for a predetermined sleep interval, changing power modes based on the status of one or more applications, automatically changing power modes based on incoming packets or a combination thereof. The device may also include a remote management module to diagnose, troubleshoot and solve problems involving one of the networks by using the device's ability to communicate using the other network. The dual mode capability of the mobile device allows a remote management server or operator to analyze, document and solve problems with the mobile device and/or its connections to a network.
