摘要

FOR PERFORMING A HANDOFF IN A MOBILE COMMUNICATION SYSTEM Methods and systems are provided for using a packet data serving node (PDSN) (341) in a wireless communication network that includes multiple logical PDSNs (342-345) each of which is associated with a particular IP address and corresponding physical interface (352-355). Through the use of multiple logical PDSNs (342-345) and interfaces (352-355), the throughput of the PDSN may be substantially increased. Additionally, the multiple logical PDSNs (342-345) and interfaces (352-355) may be used to provide redundancy in order to protect against software or hardware failures. A problem with prior art systems are that the PDSNs cannot provide as much throughput nor can they reduce the likelihood of hard handoffs. According to the methods and systems of the invention, moreover, the risk of internal hard handoffs resulting from the use of a PDSN (341) having multiple logical PDSNs (342-345) is eliminated or at least substantially reduced.
