DISCUE: Distributed caching framework at the user equipment (UE) in LTE networks
Hassan Ali Artail, Salim Mansour, Hasanin Harkous, Youssef Nasser · 2015
In this paper, we introduce a scheme of caching requested data in LTE networks. After data (eg., web pages) is cached after its first request, the subsequent requests of the same data are served from the network's caching memory directly. The idea in this scheme is new in that the caching memory is at the level of the mobile devices themselves and not in the LTE core network, as in other proposed schemes. Our approach aims to minimize the required changes in the functions of the various elements of the LTE network core for supporting the caching operations. As we illustrate in the results section, the proposed system results in lower overall data access delays, which are attributed to retrieving some of the requested data from Internet servers when such data are not found in the network.
