ABSTRACT:
Routing of packets to a mobile node in a packet switching network is controlled. Routing the packets comprises generating first routing protocol data for a network address used by a mobile node of the network, the first routing protocol data specifying a characteristic of a first route passing through a first access node of the network, the first access node serving the mobile node via a communications link, and in response to the mobile node receiving service from a second access node, generating second routing protocol data for the network address, by a routing defining process involving transmitting directed routing update messages to a limited number of the packet switching nodes. The second routing protocol data specifies a characteristic of a second route passing through the second access node such that the first and second routing protocol data are held in different sets of packet switching nodes.
