Embodiments have a master eNB with a control plane and optional data plane to user equipment and a secondary eNB with a data plane to the user equipment. The user equipment thus uses both the master eNB and the secondary eNB for data communications while receiving control information from only the master eNB. The master eNB and secondary eNB are connected with an X2 interface. When the secondary eNB desires to refresh its security key, it informs the master eNB using the X2 interface. The master eNB then uses its control plane with the user equipment to initiate a security key refresh for the secondary eNB.
