Mobility prediction in wireless, mobile access digital networks
First Claim
1. A method for predicting mobility of a mobile node relative to one or more fixed nodes in a wireless, mobile access, digital network, comprising:
- obtaining a plurality of samples of a first physical parameter the value of which is related to the mobility of said mobile node; and
statistically processing said plurality of samples and generating a predicted future value of said parameter.

Abstract
Disclosed are methods for predicting the mobility of mobile nodes in third generation and beyond wireless, mobile access Internet protocol-based data networks embodying IETF Mobile IP support, as well as in wireless LANs. Conventional Mobile IP mobility detection is replaced with deterministic, stochastic, and/or adaptive methods to predict the mobility of a mobile node in the network employing network logic layer (L3) packet latency characteristics. The method is useful for providing pre-notification that a communication hand-off condition is imminent to enable fast route pre-establishment and reduced packet latency, and for optimizing quality of service by facilitating selection of best base station transceiver in overlapping cell environments, among other applications.
