Abstract
A system and method for monitoring subnet relations in a wireless communication system is disclosed. A wireless communication device is provided and is located in a first subnet. When the wireless communication device executes a handoff to a second subnet, a mobility agent server notifies a virtual operator server of the handoff. As a result of the handoff, a subnet relation is created between the first subnet and the second subnet that is stored and later used to control how the wireless communication device uses power by placing network interface systems that cannot be used in a power-saving mode.
