System for context transfer for wireless internet devices


Abstract
A system and method for feature context transfer store all currently "active" feature contexts locally at an Access Router (AR), and store all "inactive" feature contexts centrally in a main database. The main database can be accessed by all the ARs within the same administrative domain. When a new microflow becomes active, its active feature contexts are brought from the main database and loaded into the local directory, thus replacing any inactive feature contexts that are not needed at the time.
