Abstract:
There have been tremendous advances over the past decades when it comes to wireless access technologies. Nowadays, mobile devices are equipped with several wireless access technologies like 3G, 4G or WiFi. Currently, these mobile devices can communicate using one access technology at a time. However, there is a big potential for improving network capacity and enhancing user 'Quality of Experience' if these access technologies are integrated. Such an integration would allow access technologies to cooperate and work simultaneously in a heterogeneous environment from which both the end users as well as the mobile operators can benefit. In this paper, it is investigated how to tackle the simultaneous usage of wireless access technologies. For this purpose, a practical example of a 3GPP LTE and a non-3GPP WLAN integrated heterogeneous network is considered. Furthermore, a novel decision mechanism is proposed, that focuses on optimizing the flow management of user traffic flows based on a mathematical formulation of the system. The mathematical model is implemented using Linear Programming techniques. The paper demonstrates the gains and benefits that are achieved from using such innovative decision mechanism as well as the benefits that arise from the simultaneous usage of wireless heterogeneous accesses.
