20100172293 | Lightweight Mobility Architecture - Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains a database of currently attached devices and their current access domain location. The mobility manager may then detect, 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 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. | 07-08-2010 |
