Abstract

A mobile node includes first and second communication interfaces for connecting to first and second types of networks, respectively. The mobile node also includes a processor capable of connecting to a first type of network via the first communication interface. The processor can monitor location information from the first type of network, the location information being representative of a geographic area within which the mobile node is currently located and available as a result of the connection to the first type of network. The processor can determine if the mobile node is currently located in an area associated with a second type of network based upon the monitoring of the location information. If so, the processor can turn on the second communication interface, and effectuate a handoff of the mobile node from the first type of network to the second type of network via the second communication interface.
