Modified architecture of Wi­-Fi OFFLOAD

DOI №______

Abstract

Due to the growing variety of personal devices, there is a demand for more high-speed network connection. To cope with increasing traffic volumes, mobile network operators need to implement more high-speed and economical radio technologies, increase spatial efficiency by deploying small cells, thus ensuring balanced development of heterogeneous networks.
Mobile operators plan to unload their networks from data traffic in the most profitable way and improve their economic status. The change in concept was also due to the fact that further technological developments and improvements in cellular network architecture are impossible due physical constraints. In addition, providing high bandwidth and high data rates requires significant capital investments, which is economically not profitable.
Due to the fact that for several years now the traffic of data in cellular networks shows steady growth, operators in this situation remains only one opportunity to meet the needs of their customers — to increase the density of coverage, thus providing greater bandwidth per one subscriber. In the process of increasing in the density of the coating is right idea, but mobile operators have to take into account the economic performance of the equipment of one station.
Another solution of the problem is the Wi-Fi Offload technology, designed to unload mobile operators’ networks from data traffic through the use of Wi-Fi technology. In this case, subscriber data traffic is offloaded from a mobile operator’s network to a separate radio network operating using its own trunk channels. Also, it is possible to provide subscribers services through partner networks in the same way as it is done when the subscriber is in roaming.
The urgency of the modification of the Wi-Fi Offload architecture is due to the fact that it will give the modern user the opportunity to receive high-quality access to Internet resources or to the service of a mobile operator. The operator, in turn, gets the opportunity to service an additional number of subscribers, and also reduces the loading of their macros.
