Publication number: 20210345205Abstract: A method performed by a target access node for handling data packets in a handover of a User Equipment, UE, from a source cell served by a source access node, to a target cell, served by the target access node in a wireless communications network is provided. The target access node receives a status report of last received data packet in the UE from the source access node. The target access node performs a data packet duplication check based on the information comprised in the status report. The target access node then sends to the UE, only data packets which have not already been received by the UE from the source access node, based on the outcome of the duplication check.Type: ApplicationFiled: October 29, 2019Publication date: November 4, 2021Inventors: Claes-Göran PERSSON, Paul SCHLIWA-BERTLING, Johan Rune, Pontus WALLENTIN, Pradeepa RAMACHANDRA
