The mobile networking
Abstract:
Mobile Networks are at the brink of becoming truly All-IP Networks, providing all services through IP technology. This opens the door for new advancements
of
mobile systems and all parts of them, along with the efforts taken to advance Internet technology. The necessity to advance the IP based mobile network in the upcoming
years stems from the rapid growth of IP multimedia application traffic. Such demand
for an unprecedented network capacity will not be supported by a same level growth
of the revenue. Consequently, to cover future investments a higher network efficiency in CAPEX and OPEX is needed. In addition to an expected increase in
efficiency, new, innovative user-centric services are needed to exploit the value of the
mobile
network: The latter address emerging resources inside the network such as storage and processing power that demand for new mobility management and
resource management solutions taking service locality, service roaming, virtualization
of resources and user perceived quality into account.
Ⅰ）
Mobile Networks
This workshop focuses on the mobile core network. We take a deployment of air interfaces such as LTE-Advanced for well underway and focus in concepts
and
technologies for the advancement of the core network. Contributions are sought for all
network layers ranging from high-speed transport to service delivery platform.
With this workshop, we plan to continue the workshop AMN 2011 to be held at ICC 2011 in June also in 2012 to establish a workshop series right in time
when industrial and academic research is taking shape and progressing
towards commercialization.
The emerging variety of multimedia services also pushed by the heterogeneity of
end systems ranging from traditional mobile phones to high resolution portable smart screens, demands for new, efficient resource management schemes such as
mobile network embedded CDNs or content specific mobility management schemes.
With
available processing and storage space in the network, services do not any longer have to remain statically at a central server, but may move closer to
the consumer. Such migration is not limited to one operator domain, but service programs may
roam between operator networks. Diversified resource control also demands for a
next generation of quality of
service provisioning taking the user perceived quality resp.
Quality of Experience into account. In order to flexibly realize such new network and
service solutions a level of indirection between the service delivery platform and the
transport network is needed. Sophisticated mechanism are sought to allow for network
resource isolations, realizing an abstraction layer for flexible control and management of coexisting, specific networks on one infrastructure substrate. It also
allows abstracting from transport networks, supporting the flexible introduction of
high
speed bit transport through advanced (e.g. optical) network technologies. Moreover we see a number of areas, which have to be additional addressed
in
research for a sound evolution of the All-IP mobile core network. Most prominently a
new emerging business environment that includes but is not limited to new business
roles that relate to Network Virtualization, Cloud Computing and System Adaptability
to the exploding number of 3rd party applications, taking into account the role of new
players in an open service market and the economic market pressure that is grounded in fierce competition.
Ⅱ）3G and 4G
This sudden 3G boom also gave mobile network operators enough incentive to invest huge sums of money for equipment necessary to get their 3G services functional.
However, with the recent advent of 4G wireless networking, it all seems to be
changing yet again. Now, those very operators who had readily plunged into 3G have their doubts about its sustenance. Carriers who are just thinking of wireless networking seem to prefer going in for the fourth-generation systems, better known as 4G. Why is this 3G vs. 4G issue even coming up? What is the reason behind this huge generation leap, as they say? Here is why 4G might soon become the preferred wireless network: ??Less Expensive
Experts think that 4G systems, which is still only starting off in many countries of the
world, will end up being much cheaper than 3G. They believe that the new system can be built over the existing system, without the operator having to completely retool and purchase and entirely new spectrum. While 3G requires an entirely new spectrum and standard, 4G makes good use of existing technologies. In fact, 4G is capable of seamless integration with 2G, Bluetooth and even LAN networks, which makes it far more versatile than its
predecessor. ??Much Faster Needless to say, 4G also provides far faster data services than its predecessor. This would also make the going much easier for those working with heavy applications, such as advanced VoIP and video streaming. 4G networking transmits speeds of greater than 20MB per second, hence, can offer high bandwidth services anywhere it is installed, including homes, offices and public places such as airports, cafes and so on.
