Abstract  Abstract

embodiment has a main eNB and an auxiliary eNB wherein the main eNB has to control surface and an optional data of the user equipment side and the secondary eNB has to the data plane of the user equipment. so the main eNB and an auxiliary eNB is used for data transmission by the user equipment at the same time only receives the control information from the master eNB. a main eNB and an auxiliary eNB through X2 interface connection. when the secondary eNB wants to refresh the security key it informs the master eNB X2 interface is used. a main eNB and then using the control surface with user equipment refresh to initiate security key of the secondary eNB.

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.
