Automatic enabling ENDC (evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN) new radio (NR)—dual connectivity for 4G long term evolution (LTE) evolved node B (eNB)
An evolved Node B (eNB) for providing automatic ENDC enabling. Measurement reports are generated during a prior handover by user equipment (UE) configured in 5G NR connected mode. The measurement reports are received at a 4G LTE evolved Node B. Based on the measurement reports, the 4G LTE eNB determines a number of Automatic ENDC Enable (AEE) criterion being met during a predetermined time period that is greater than a threshold. In response to the number of Automatic ENDC Enable (AEE) criterion met during the predetermined time period being greater than the threshold, ENDC is automatically enabled for the 4G LTE eNB.
