TEMPORARY STORING DEVICE FOR PREVENTING DATA LOSS DURING HANDOVER TO SUPPRESS DEGRADATION OF HANDOVER COMMUNICATION QUALITY, A SYSTEM THEREOF, AND A METHOD THEREOF

摘要

PURPOSE: A temporary storing device for preventing data loss during handover, a system thereof, and a method thereof are provided to prevent an End-to-End retry process by retransmitting data stored temporarily therein irrespective of generation of a drop of transmitting data.;CONSTITUTION: A first RNS (Radio Network Subsystem)(100) controls a user terminal. A second RNS(200) receives a control right of the user terminal during a first RNS handover. A core network(300) connects a first RNS with a second RNS. A temporary storing device(400) stores temporarily the data to be transmitted from the core network to the first RNS. The temporary storing device transmits the data corresponding to a handover time among the temporarily stored data.;COPYRIGHT KIPO 2010
