Abstract: A packet switched radio telecommunication system supporting hard handover adapts Always_on technology to a link between a target packet data serving node (PDSN) and a support PDSN. The support PDSN assigns a temporary IP address to a mobile terminal in its service area, and transmits handover data and the mobile terminal's temporary IP address to the target PDSN via a direct link when the mobile terminal leaves the service area. The target PDSN, upon receiving a registration request for the temporary IP address from the mobile terminal moved to its service area, temporarily registers the temporary IP address in an IP pool. The target PDSN receives down-link frame data for the mobile terminal at the temporarily registered IP address from the support PDSN via the direct link. A new temporary IP address is assigned by the target PDSN when data transmission/reception is complete to the mobile terminal.
