ABSTRACT:
Methods and apparatus are disclosed for reducing latency in a Mobile IP environment. These embodiments are particularly applicable in a 3GPP2 architecture using Mobile IPv6. Each of the features disclosed may be implemented separately or in combination with one another, and include replay protection, duplicate address detection, and updating state information at a PDSN in a system implementing route optimization.
