Abstract:
A method of routing messages destined for a mobile node (6) in a communications system, such as the Internet, including sending the messages to a proxy node (18) according to reachability information recording the current reachability of the mobile node (6), as well as user preference information provided by a service controller (13), which is able to divert an incoming message to an address specified by the user, and in the absence of current location information for the mobile node (6), can intervene to send an incoming message to a default location such as the proxy node (18).
Abstract:
Data is routed through the Internet to a mobile node by using home agents and foreign agents to provide mobility functions. Data transfer rates to the mobile node are improved by providing for transfer of data from the home agent to a plurality of foreign agents on a round-robin basis, which can be enhanced by checking the quality of the connection between the foreign agent and the mobile node and re-routing the data through another foreign agent if certain predetermined quality criteria are not met.
