Abstract
A system and method provide seamless data network telecommunication service to a mobile wireless node during mobile wireless call handoff from a first base station to a second base station. Prior to call handoff, communication content addressed to the mobile wireless node is routed to a first address for delivery to the mobile wireless node via the first base station. Upon initiation of the call handoff, the communication content is routed to a second address for delivery to the mobile wireless node via the second base station. At the same time, routing of the same communication content is continued to the first address. Upon completion of the call handoff, communication content routing to the first address is terminated.
