A device, method and system of using a first user equipment (UE) as a small evolved NodeB (eNB) for a small cell may comprise receiving a first long term evolution (LTE) packet from a second UE over the small cell; converting the first LTE packet into a first transmission control protocol/Internet protocol (TCP/IP) packet, wherein the converting includes retrieving payload data from the first LTE packet and encapsulating the payload data into the first TCP/IP packet by adding a TCP/IP header to the payload data, and wherein the TCP/IP header includes an IP address of an Evolved Packet Core (EPC) network associated to Internet based on a TCP/IP tunneling protocol; and transmitting the first TCP/IP packet to an Internet destination via the EPC connected with the first UE through an Internet server over a local area network (LAN).
