The Developing Trend of MBB Network
Video Streaming
Webpage Browsing
• The web browsing & video streaming will be the main components of the mass mobile
broadband traffic
• The development of mobile broadband network will witness the same trends and
challenges that has appeared in fixed broadband network development
• The construction of mobile broadband network can refer to fixed broadband network
construction experience

• Metro aggregation network is FMC ready, but not E2E FMC available
• The separation of IP RAN service stream by MPLS-TP & IP/MPLS networks breaks
E2E service features such as E2E protection & configuration
• The existing IP RAN equipment doesn’t fulfill strong IP/MPLS features as router does
• UPE routers are usually too big & expansive in metro access

Leased Line Cost
Data service consume more bandwidth but bring less revenue.
Traditional TDM based technology can not support 3G/LTE.
The situation is even worse in case of renting E1 LL from 3rd party.
Migrate to all-IP is the long term strategy.
Mobile Operator’s Challenge for Backhaul Bandwidth
HUAWEI TECHNOLOGIES CO., LTD. Page 6Huawei Confidential
Mobile operator rent mobile backhaul network infrastructure (such as optical fiber, microwave, site pole/room, routers, transmission devices, etc) is very popular in Europe and North America:
1. USA, Sprint (Pure Mobile) and AT&T (Fixed + Mobile) rent backhaul from comcast (TV Operator)
2. UK, O2 rent backhaul from BT
3. Germany, T-Mobile rent backhaul from T-Home
4. Spain, Vodafone rent backhaul from Tele2
……
BUT, we still need to think about a lot
It’s Popular to Be the Pipe Operators
HUAWEI TECHNOLOGIES CO., LTD. Page 7Huawei Confidential
All the media in different network part,
need the universal pwe3 pipes go through
whole network, universal O&M
Integrate all the access method
(fiber, xDSL, PON, etc) into
same device.
Larger coverage, make use
of any available transport
media.

Without reasonable price and good
service, mobile operator will choose to self
build backhaul.

How to keep the future evolution, while no

need high efficiency NMS tools, for device,
