In order to increase the capacity of mobile networks, operators are investigating the use of unlicensed spectrum in addition to their licensed spectrum. Already today it is possible to integrate WiFi networks into the core networks and perform offloading of traffic to a WiFi network. In future releases of 3GPP a tighter interaction of WiFi and LTE is foreseen that will even enable the aggregati...

Mobile network traffic is growing rapidly, and service providers must manage their networks efficiently to meet consumer demand. Mobile data offloading is the use of complementary network technologies for delivering data originally targeted for cellular networks. Access network discovery and selection function (ANDSF) is the most complete 3GPP approach to date for controlling offloading between...

Recent trends show that Internet traffic is increasingly dominated by content, which is accompanied by the exponential growth of traffic. To cope with this phenomena, network caching is introduced to utilize the storage capacity of diverse network devices. In this paper, we first summarize four basic caching placement strategies, i.e., local caching, Device-to-Device (D2D) caching, Small cell B...

The connected and autonomous vehicles (CAV) applications services-based traffic make an extra burden on the already congested cellular networks. Offloading is envisioned as a promising solution to tackle networks’ explosion problem. Notably, vehicular offloading leveraging different communication network (VCN) modes one of potential techniques address data problem in This paper surveys state-of...
