A method performed by a base station comprises: initiating a QoS-flow to DRB remapping; informing a target base station that the remapping is ongoing; and providing the target base station an old and a new QoS-flow to DRB mapping, wherein the old mapping was in place before the remapping, and the new mapping will be in place after the remapping. Another method performed by a base station comprises: receiving an indication from a further base station that QoS-flow to DRB remapping is ongoing; receiving an old and a new QoS-flow to DRB mapping from the further base station; and receiving signals from a wireless device using the old and new QoS-flow to DRB mappings. A method performed by the wireless device comprises: sending data packets using a first QoS-flow to DRB mapping; receiving a new mapping; and sending an SOAR end marker, indicating that the wireless device is applying the new mapping. Also disclosed are base stations and wireless devices configured to perform the methods."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Handling service data application protocol (SDApP) end markers at handover","description":"Methods performed by base stations and wireless devices in networks are disclosed.
