Title
(EN) Managing node mobility in an IP network
Abstract
(EN) Managing mobility of one or more mobile network nodes using a home agent and a mobile router. This involves: sending mobile network node address information to the home agent from the mobile router; storing the mobile network node address information in memory, and sending subsequent messages to the home agent indicative of the current address of the mobile router, but without any mobile network node address information, unless or until changes occur to the mobile network node address information, in which case a message is sent from the mobile router to the home agent with updated mobile network node address information.
