The mobile netwo✔₽rking
Abstract:
Mobile Networks are at the brink of be¥₩©coming truly All-IP Net∞ ♠works, providing all s≥φ≠ervices through IP technology. This oσ®pens the door for new advancements
of
mobile systems and all parts of them, along with ₽γ∑the efforts taken to advance Internet technolo→∑gy. The necessity to advanc®ε$±e the IP based mobile network in the up✔coming
years stems from the rap★Ωid growth of IP multimedia application traffic. S←→β∏uch demand
for an unprecedented network capacity will not b₽★♥e supported by a same level gr®≥∑owth
of the revenue. Conse≈εquently, to cover future investment♣<s a higher network efficiency in CAP™©EX and OPEX is needed. In addition to an exp≈✘ected increase in
efficiency, new, innovative user-centric services♦φ↓ are needed to exploit the value of the&n¥★bsp;

Ⅰ）
Mobile Networks
This workshop focuses on the mobile core net<work. We take a deployment of air interfaces su$βch as LTE-Advanced for well underway an♥β d focus in concepts
and
technologies for the advancement of the co₹÷re network. Contributions aγε∏re sought for all
network layers ranging from high-speed t↓≈ ransport to service delivery pla↓>₹$tform.
With this workshop, we©σ§∏ plan to continue the workshop AMN 2011 to∏≥≥ be held at ICC 2011 in June also in 2012 to e♠↔¥₹stablish a workshop series right in tβ÷ime
when industrial and academic re§αsearch is taking shape and progressing&nb☆∑♣±sp;
towards commercialization. ∞§;
The emerging variety of m♥©₩™ultimedia services also pushed by the γ±heterogeneity of
end systems ranging from traditio∏¶nal mobile phones to high resolution &↕×portable smart screens, demands for new, effi≥<∑®cient resource management schemes↓™ such as
mobile network embedded CDNs or content specific ☆≈mobility management schemes.&nbs♣≤p;
With
available processing an≤d storage space in the network, services do α<not any longer have to r§¥✘±emain statically at a &¶✔↑central server, but may move closer to≈×
the consumer. Such migration is not limi§≤"ted to one operator doma±πin, but service progr"π↑ams may
roam between operator nΩΩetworks. Diversified resource control als'£o demands for a
next generation of quality of
service provisioning taking thε≠ e user perceived quality resp.
Quality of Experience§∑ into account. In order to flexibly 'δ>realize such new network and
service solutions a le¥ε vel of indirection between the serv↕≤¶ice delivery platform and the
transport network is needed. Sophisti↓∑λcated mechanism are sought to π↑allow for network
resource isolations, realizin♠♦∑≠g an abstraction layer for flexible cont→♦©rol and management of coexisting, specific n♠α&₩etworks on one infrastructure substrate. φ©♥©It also
allows abstracting from transport≈♦ε§ networks, supporting the flexible introduction ₩ε∑of
high
speed bit transport through advanced (e☆.g. optical) network technologies. Moreov∑λer we see a number of areas, which h✔ε♠₩ave to be additional addressed
in
research for a sound evolution of thβπ≥e All-IP mobile core network. Most promiα→÷<nently a
new emerging business environmen¶§→t that includes but is not limited to π☆new business
roles that relate to N∑↔¥εetwork Virtualization, ∑&←Cloud Computing and System Adaptability&Ω← nbsp;
to the exploding numb↔±er of 3rd party applicat₹♦∞ions, taking into account the role of new$$
players in an open service market and the econπ Ωomic market pressure that is ∏→grounded in fierce competiti™πΩon.
Ⅱ）3G and 4G
This sudden 3G boom ©δαalso gave mobile networkε§ operators enough incentive to₩φ invest huge sums of money for equipment necesΩβsary to get their 3G services functional.
However, with the rec₩↔φent advent of 4G wireless networking, i¶↕t all seems to be
changing yet again. Now, those very σ±operators who had readil ₩•→y plunged into 3G have their doubts ab'∞out its sustenance. Carriers who are just thinkin•λ₩ g of wireless networki★←ng seem to prefer going in ♥₽★for the fourth-genera≠©tion systems, better known as 4G. Why i ₩♣↕s this 3G vs. 4G issue even coming up? What is ×≥the reason behind this huge g<φeneration leap, as they say? Here is why× δ≠ 4G might soon becom e the preferred wireless network: π≈™≥ Less Expensive&n σε←bsp;
Experts think that 4G •φ∑systems, which is still only starting £off in many countries of"←φβ the
world, will end up being much cheaper than 3G♥•. They believe that the new system can be b♣ uilt over the existing system, without the opera壩tor having to complet☆ ely retool and purchase and entirely new spectrum. &↑§♥™nbsp;While 3G requires an entirely new spect×≤rum and standard, 4G makes good use of e$₩∞xisting technologies. In fact, 4G is capabl×✘≈e of seamless integration with 2G, Bluetooth and §σβ§even LAN networks, which makeππs it far more versatile than it±€↓£s
predecessor. '§§≈Much Faster Needless to say, 4G also pro♠εvides far faster data services than its§φλ predecessor. This would al€δπso make the going much easier foπα↑r those working with hea&♦vy applications, such as advanced VoIP and×₹ video streaming. 4G networking t£σ₩ransmits speeds of greater than 20MB per s£↔↑↔econd, hence, can offer high bandwidth services a₽↑♦nywhere it is installed, inclu∞→♥ding homes, offices and pubΩΩγlic places such as airε★↕ports, cafes and so on.
