Method and System for Providing an Automatic Failover When Cell Phone Signals Are Weak

Disclosed is a method and system for automatically and transparently switching from one network to another by maintaining a same number and carrier when a cell phone's signals are weak. The method and system performs the switching over based on monitoring the signal strengths of one or more networks. The one or more networks include, but need not be limited to, cellular networks, Third Generation (3G), Fourth Generation (4G), Wireless Fidelity (Wi-Fi) for

Voice over IP (VOIP) applications and Bluetooth. Each network of the one or more networks requires a different set of software for establishing a connection and is assumed to be of client-server type. For example, the method and system monitors signal strength capabilities of both cellular network and Wi-Fi network. When the method and system detects that a call quality of the cell phone is poor in the cellular networks, the method and system arbitrates a move of existing cellular calls of the cell phone to the Wi-Fi network. The arbitration is based on whether such a move provides a good or better call quality with reduced costs for the cell phone user. The cell phone utilizes one or more algorithms to determine

which system (cellular or Wi-Fi or 4G) provides more efficient Quality of Service (QoS) and uses less battery to power the connection/communication.

In an embodiment, the method and system monitors the signal strengths of the one or more networks using pings to determine the QoS of the one or more networks. The method and system, then, estimates power consumption based on the signal strengths and the QoS of the one or more networks. Based on the estimated power consumption, the method and system determines an optimal and efficient network as an alternate network from the one or more networks for switching over to when the cell phone's signals are weak in the cellular network. The method and system performs the switch over transparently without requiring a user of the cell phone to manually launch any application. The method and system also enables the user to configure certain network connection parameters. For example, depending on a...
