Abstract :
Mobile and wireless
networks have made tremendous growth in the last fifteen years. Nowadays many
mobile phones have also a WLAN adapter. One may suppose that near soon many
mobile phones will have WiMAX adapter too, besides their 3G, 2G, WLAN,
Bluetooth etc. adapters. Today 3G
mobile systems are on the ground providing IP connectivity for real-time and
non-real-time services. On the other side, there are many wireless technologies
that have proven to be important, with the most important ones being 802.11 Wireless
Local Area Networks (WLAN) and 802.16 Wireless Metropolitan Area Networks
(WMAN), as well as ad-hoc Wireless Personal Area Network (WPAN) and wireless
networks for digital TV and radio broadcast.
The
main contribution of this paper is definition of 5G (Fifth
Generation) mobile network concept, which is seen as user-centric concept
instead of operator-centric as in 3G or service-centric concept as seen for 4G.
In the proposed concept the mobile user is on the top of all. The 5G terminals
will have software defined radios and modulation scheme as well as new
error-control schemes can be downloaded from the Internet on the run. The
development is seen towards the user terminals as a focus of the5G mobile
networks.
The
terminals will have access to different wireless technologies at the same time
and the terminal should be able to combine different flows from different
technologies. Each network will be responsible for handling user-mobility,
while the terminal will make the final choice among different wireless/mobile
access network providers for a given service. The paper also proposes
intelligent Internet phone concept where the mobile phone can choose the best
connections by selected constraints and dynamically change them during a single
end-to-end connection. The proposal in this paper is fundamental shift in the
mobile networking philosophy compared to existing 3G and near-soon 4G mobile
technologies, and this concept is called here 5G.
