The explosive growth of mobile video traffic brings a great pressure on LTE mobile networks. Deploying caches at the evolved packet core (EPC) and radio access network (RAN) in LTE mobile networks can efficiently relieve this pressure by reducing duplicate content transmissions. In this paper, we propose a collaborative caching framework for the LTE mobile network with caches deployed at the EPC and RAN to reduce the bandwidth cost of Internet access and improve the enduser experience in terms… CONTINUE READING
