Abstract
A first packet is received at a network element from an E-UTRAN Node B (eNB) of an E-UTRAN access network via a secured communications tunnel of a secured connection, where the first packet encapsulates a second packet therein. It is determined whether the network element serves both a security gateway functionality and a serving gateway functionality of a core packet network based on the first packet and the second packet. The network element negotiates with the eNB to switch further communications from a tunnel mode to a transport mode of the secured connection if it is determined that the network element serves both the security gateway functionality and the serving gateway functionality. Thereafter, the network element exchanges further packets with the eNB via the transport mode of the secured connection after the eNB switches from the tunnel mode to the transport mode.
