Title:
LIGHTWEIGHT MOBILITY ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO2008088271
Kind Code:
A8
Abstract:
Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains (Sl) a database of currently attached devices and their current access domain location. The mobility manager may then detect (S2), for a device registered in the database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to the considered device. The mobility manager should at least obtain an indication of such a change of access domain. In response to a detected change of access domain, the mobility manager arranges (S3) for a reconfiguration of the network to forward traffic destined to an IP address of the device in the first access domain to a new location in the second access domain. In this way, the mobility manager allows the device to keep its IP address when moving between access domains.
