EMOBILE: the mobile broadband revolutionist - Huawei

Winners
IP transformation as the core of its strategy, opting
for a 3G-ready network that was optimized for the
currently prevalent 2G environment.
China Mobile selected Huawei as its strategic
partner to realize All-IP transformation due to the
latter’s impressive aggregate experience in numerous
related fields. The Huawei solution incorporated
2G/3G IP-based core networks coupled with
a voice quality enhancement (VQE) solution
capable of delivering carrier-class QoS for voice
services. With a resulting 50% efficiency increase
over TDM, the entire network was restructured to
preempt the hidden problems that can infect a new
Reaping major benefits
Project progress was mirrored by the cumulative
benefits visited upon China Mobile. From 2004 to
2007, subscriber numbers doubled, during which
time traffic skyrocketed to 1.8 trillion minutes with a
completion rate of 99%. OPEX was greatly reduced,
with average MSC power consumption dropping
by 63%, and 20% OPEX savings were gained by
optimizing systems and centralizing O&M.
These reductions allowed China Mobile to
penetrate the vast rural market, which propelled
IP transformation of the whole network is a grand project,
it requires a partner who understands both IP and mobile
communications technologies. We are pleased to have
Huawei as our partner.

IP infrastructure.
To meet the requirements that the new
network dealt, China Mobile adopted a multilevel
management system with centralized realtime
monitoring, dual-homing, N+1 backup, and
mobile switch center (MSC) pool. These measures
optimized security for the variety of All-IP NEs.
The risk minimization strategy established three
major strategic phases. The first phase constructed a
tandem IP backup network parallel to the existing
tandem TDM network in order to seamlessly
migrate traffic to the IP network. The second phase
expanded the IP bearer layer to the local network,
under which the control and transmission bearers
were based on All-IP. The final stage transformed
the wireless access layer to All-IP.
the company’s growth rates with considerable force.
By utilizing a dual 2G/3G IP based core network,
China Mobile completed a crucial network control
and service transmission phase in terms of 3G
infrastructure without activating any of the risks
that accompanied the scheme.
China Mobile acted swiftly and confidently in
the face of a plethora of challenges from its rivals
coupled with the lagging legacy network. The
bold move to All-IP and the choice of Huawei
as its partner spearheaded a flexible, reliable, and
expandable network that drove China Mobile’s
efforts to widen their market lead. As the network
begins to accommodate more 3G traffic, the results
of this far-sighted strategy are becoming more
evident.
