Abstract  Abstract

METHOD AND EQUIPMENT FOR HANDOFF OF A WIRELESS PACKAGE DATA CONNECTION. A novel method and equipment for seamless handoff of a mobile station (MS) between radio access networks (RANS) using different types of wireless interfaces is described. The embodiments described enable a mobile station to be passed between different RANs without causing routing ambiguities and without substantial loss of network data. When moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, a mobile station determines if routing ambiguities may result from the RAN change and, with based on this determination, triggers a re-registration of your network address. An external agent (FA) within a packet data server (PDSN) node monitors re-registered records of network addresses being created for the same mobile station. Based on this determination, the PDSN terminates redundant R-P network connections that result from mobile station movement between different RANs.
