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

Document Type and Number:

WIPO Patent Application WO2005010708

Kind Code:

A3

Abstract:

Methods and systems are provided for performing handoff in a wireless communication system (100) that uses a packet data serving node (PDSN) (141) having more than one Internet Protocol (IP) address. A mobile station (MS) (101) uses a first packet control function (PCF) (131) to establish a first session using a first IP address of the PDSN when in an area being served by a first base transceiver station (BTS) (111). The MS uses a second PCF to establish a second session with a second IP address of the PSDN when in an area served by the second BTS. The PSDN treating the handoff between the first IP address and the second IP address as a soft handoff.
