ABSTRACT:
The present invention discloses performing a care of address registration of a mobile node at a home server unit of a home network of the mobile node, the home network comprising a plurality of home server units being arranged to maintain a binding between a home address of a mobile node and its current care of address from a visited network. A mobile node selects a first home server unit for registration and sends a binding update message to the first home server unit. In response to the received binding update message the first home server unit decides whether a binding update is to be rejected. In case it is decided that the binding update is to be rejected, the first home server unit selects a second home server unit. In a binding acknowledgment message information about the second home server unit is included and a binding update at the second home server unit is confirmed. The binding acknowledgment message resulting therefrom is sent to the mobile node.
