METHODS AND SYSTEMS FOR PROVIDING IMPROVED HANDOFFS IN A WIRELESS COMMUNICATION SYSTEM

摘要

Methods and systems are provided for using a PDSN in a wireless communicatio n network that includes multiple EP addresses and multiple corresponding physical interfaces. Through the use of multiple EP addresses and interfaces , the throughput of the PDSN may be substantially increased. Additionally, the multiple W addresses and interfaces may be used to provide redundancy in ord er to protect against software or hardware failures. According to the methods a nd systems of the invention, moreover, the risk of internal hard handoffs resulting from the use of a PDSN having multiple IP addresses and interfaces is eliminated or at least substantially reduced.
