METHOD AND APPARATUS FOR PERFORMING HANDOVER IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18418970 titled 'METHOD AND APPARATUS FOR PERFORMING HANDOVER IN WIRELESS COMMUNICATION SYSTEM
The abstract describes a method in a wireless communication system where a terminal receives a radio resource control (RRC) reconfiguration message for a handover from a source base station. The message configures a first data radio bearer (DRB) as a dual active protocol stack (DAPS) bearer and a second DRB as a non-DAPS bearer. The method involves indicating PDCP data volume for the first DRB to a target base station's MAC entity and performing PDCP re-establishment for the second DRB if needed.
- Method for handover in a wireless communication system

Questions about the technology: 1. How does this method improve the efficiency of handover processes in wireless communication systems? 2. What are the key benefits of configuring DRBs as DAPS and non-DAPS bearers in terms of network performance and reliability?
Original Abstract Submitted
A method, performed by a terminal, in a wireless communication system is provided. The method includes receiving, from a source base station, a radio resource control (RRC) reconfiguration message for a handover, the RRC reconfiguration message configuring a first data radio bearer (DRB) as a dual active protocol stack (DAPS) bearer and a second DRB as a non-DAPS bearer, for the first DRB, in case that an uplink data switching is requested from an upper layer, indicating, by a packet data convergence protocol (PDCP) entity for the DRB, a PDCP data volume excluding a PDCP Control protocol data unit (PDU) associated with the source base station, to a medium access control (MAC) entity for a target base station, and for the second DRB, in case that an indication of PDCP re-establishment is set, performing a PDCP re-establishment for the second DRB.
