ABSTRACT:
Methods and systems are provided for using a PDSN in a wireless communication network that includes multiple IP addresses and multiple corresponding physical interfaces. Through the use of multiple IP addresses and interfaces, the throughput of the PDSN may be substantially increased. Additionally, the multiple IP addresses and interfaces may be used to provide redundancy in order to protect against software or hardware failures. According to the methods and 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.
