Abstract
A method and system enabling roaming between different wireless networks. A mobile device supporting low and high-tier wireless network standards is adapted to roam between a low-tier wireless network and a high-tier wireless network with lower bandwidth but more mobility than the low-tier wireless network. Via a virtual GPRS support node, a plurality of data packets and control signals are delivered between low and high-tier wireless networks.
