Abstract
The invention discloses a new protocol to minimize data loss, reduce overhead transmissions on the system, reduce time delays and signal interruption during a handover in a Mobile IP system. Prior art Mobile IP systems transfer policy and charging rules for a particular mobile user device from a server to a gateway after the handover occurs. The invention allows for the transfer of the policy and charging rules during the handover procedure so that the system does not need to wait on a subsequent transmission of the policy and charging rules in order to process the transmissions sent by or to the mobile user, which results in minimized data loss, reduced overhead, and reduced time delays and signal interruption.
