Abstract
A network element is configured to receive a first packet from a first eNodeB (eNB) of the packet network via a first secured X2 link. The network element decrypts the first packet to reveal a second packet encapsulated within the first packet. The network element determines a second secured X2 link associated with a second eNB as an intended recipient of the second packet. The network element encrypts the second packet to generate a third packet and transmits the third packet to the second eNB via the second secured X2 link. The network is coupled to various eNBs of the packet network via various secured X2 links, respectively.
