Abstract
Abstract: In this paper we propose new design for network and protocols architectures of future 5G mobile networks. The proposed design
is based on user-centric mobile environment with heterogeneous radio access technologies. In the proposed design the user terminal has
possibility to change the Radio Access Technology - RAT based on certain criteria. For that purpose we split the network layer on two
network sub-layers, lower and upper one. The lower one is network IP layer, providing identification of the wireless interface to the given
mobile network, so there are different IP addresses for different RAT interfaces. The upper IP layer, so-called here virtual network layer
provides identification of the network layer towards the applications in the mobile terminals, and there is only one IP address, so tunneling
is used over different RATs towards the central tunnel endpoint called Policy Router, which establishes IP tunnels to the mobile terminal
via different available RATs to the terminal. The selection of the RAT is performed by the mobile terminal using the proposed user agent
for multi-criteria decision making based on the experience from the performance measurements of different RATs performed by the mobile
terminal in the given time window in the past. We present results of simulation analysis of the proposed intelligent Mobile RAT selection
algorithm on the user-side for scenario with two RAT technologies, one Wireless WAN and one Wireless LAN. The obtained results
showed that the proposed algorithm is significantly better compared to the traditional approaches for RAT selection. Also, the proposed
solution in fact provide possibility for throughput aggregation on the network layer, where we already have carrier aggregation on Layer 2
in 4G technologies such as LTE-Advanced.
