MOBILITY INTERRUPTION REDUCTION IN MULTI-RAT DUAL-CONNECTIVITY (MR-DC)

摘要

Apparatus and methods are provided for mobility interruption reduction with multi-RA dual-connectivity (MR-DC). In novel aspect, the UE with configured transceiver data with at least one source nodes, suspends data transceiving with the first source node upon receiving a reconfiguration message from one of the source nodes, keeps data transceiving with the second source node when accessing a first target node, wherein the second source node is one of the source nodes with active data transceiving with the UE, and suspends data transceiving with the second source node when accessing a second target node if configured. In some embodiments, the UE either keeps the source SN or the source MN while accessing the target MN or target SN by suspending the source MN or source SN.
