Claim of US Patent No. 10,560,887

1. A method of wireless communications by a user equipment (UE), comprising:communicating with a first node over a first radio access technology (RAT) and a second node over a second RAT;
identifying a common bearer used to convey inter-RAT network traffic to the first node over the first RAT and the second node over the second RAT, wherein the common bearer conveys the inter-RAT network traffic using inter-RAT aggregation;
identifying an intra-RAT handover event from the second node to a third node and associated with the inter-RAT aggregation;
determining whether the third node of the handover event supports the common bearer;
determining whether the inter-RAT network traffic between the UE and the first node over the first RAT and the third node over the second RAT is supported by the common bearer at the third node of the handover event; and
adapting, by the UE, network traffic routing between the UE and the first node and the third node based at least in part on determining whether the third node of the handover event supports the common bearer and determining whether the inter-RAT network traffic is supported by the common bearer at the third node of the handover event.
