5G Mobile Phone Concept
[attachment=37387]
Abstract
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. Then, the concepts of 4G is
already much discussed and it is almost certain that 4G will
include several standards under a common umbrella, similarly to
3G, but with IEEE 802.xx wireless mobile networks included
from the beginning. 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 the 5G 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.
INTRODUCTION
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. Using
IP for both, 2.5G or 3G Public Land Mobile Networks
(PLMN) on one side and WLAN on the other, raised research
on their integration, which was mainly divided into loose [1]
and tight [2] coupling. Regarding the 4G, its focus is towards
seamless integration of cellular networks such as GSM and
3G, WLAN and Bluetooth [3], [4], and [5]. Multimode user
terminals are seen as must have for 4G, but different security
mechanisms and different QoS support in different wireless
technologies remain a challenge. However, AAA integration
among different wireless networks [1] (e.g. PLMN and
WLAN) is functioning in practice even today. But, different
wireless networks from a single terminal are used exclusively,
that is, there is no combining of different wireless access
technologies for a same session (e.g., FTP download).
CONCEPT FOR 5GMOBILE NETWORKS
The 5G terminals will have software defined radios and
modulation schemes as well as new error-control schemes that
can be downloaded from the Internet. The development is seen
towards the user terminals as a focus of the 5G 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. The
vertical handovers should be avoided, because they are not
feasible in a case when there are many technologies and many
operators and service providers. In 5G, 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. Such choice will be
based on open intelligent middleware in the mobile phone.
Application layer
Regarding the applications, the ultimate request from the 5G
mobile terminal is to provide intelligent QoS management over
variety of networks. Today, in mobile phones the users
manually select the wireless interface for particular Internet
service without having the possibility to use QoS history to
select the best wireless connection for a given service. The 5G
phone shall provide possibility for service quality testing and
storage of measurement information in information databases
in the mobile terminal. The QoS parameters, such as delay,
jitter, losses, bandwidth, reliability, will be stored in a database
in the 5G mobile phone with aim to be used by intelligent
algorithms running in the mobile terminal as system processes,
which at the end shall provide the best wireless connection
upon required QoS and personal cost constraints.
CONCLUSIONS
In this paper we have proposed 5G mobile phone concept,
which is the main contribution of the paper. The 5G mobile
The proposed concept adapts Open Wireless Architecture
proposed for 4G mobile terminals, and provides further
changes from network up to application layer. The network
layer is divided into two sub-layers to provide all-IP
connectivity in environment with plenty of wireless/mobile
technologies as well as network and/or service providers. Open
Transport Layer is proposed with aim to allow usage of
wireless specific implementations of transport protocols.
Finally, we propose possibility for selection of different
wireless technologies upon different QoS constraints (and cost
constraints) for different services, real-time (VoIP, streaming,
IPTV etc.) or non-real-time (web, messaging, gaming etc.).
