Abstract
Methods and apparatus for compressing registration request and reply messages are disclosed. A compressed registration request is sent by a Mobile Node to a Foreign Agent or a Home Agent (in the case of a co-located care-of address). Communication with the Mobile Node is performed using compressed registration messages, while communication between a Foreign Agent and Home Agent is performed using standard registration request and reply formats. Thus, when a Foreign Agent receives a compressed registration request, it expands the registration request and sends it to the Home Agent for processing. Upon receipt of the registration reply from the Home Agent, the Foreign Agent compresses the registration reply and sends it to the Mobile Node. When a Mobile Node registers directly with the Home Agent via a co-located care-of address, the registration request and reply messages need not be expanded, since the Home Agent is capable of interpreting, processing and generating compressed registration messages.
