Claim:
A Gateway GPRS Support Node (“GGSN”), comprising: a processor; a bus; and a memory operably coupled to the processor via the bus for storing computer instructions defining logic for operating as one of a context GGSN or as a requesting GGSN, wherein the computer instructions cause the processor to: when operating as a requesting GGSN, receive a context GGSN address responsive to a query sent to a remote network Dynamic Host Configuration Protocol (“DHCP”) server; when operating as a requesting GGSN, perform a database lookup to determine what context GGSN is assigned to provide context activation for the received address; when operating as a requesting GGSN, forward the address from the Requesting GGSN to the context GGSN; and when operating as a context GGSN, receive and process a list of assigned subnet addresses to provide context activation therefore.
