The Gap

FMC Ready

• 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

Mobile Operator’s Challenge for Backhaul Bandwidth Leased Line Cost

Region North America

400USD / Month

Europe

400～1950Euro / Month

Japan（（Emobile））

1100USD / Month

Dilemma of mobile broadband backhaul

E1 LL fare

E1 LL cost depends on distance & bandwidth E1 LL is more popular in west Europe and North America because of regulation and legislation.

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.

It’s Popular to Be the Pipe Operators 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 HUAWEI TECHNOLOGIES CO., LTD.

Key Issues to Be Discussed Issue

Requirement

Traffic

Cost per bit, fast provisioning, wide coverage

2G/3G Voice without convergence, 3G data/ LTE with convergence.

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

GSM (Abis over TDM/IP) 3G (Iub over IMA/IP) LTE (S1/ X2 over Ether/IP)

One box all interface, universal PWE3 for all services.

Leverage the rich interface type, and the high interface density

Larger coverage, make use of any available transport media. Line Synchronization with different tech, to meet different scenarios. Less delay (10ms with LTE), less jitter, less drop.

Integrate all the access method (fiber, xDSL, PON, etc) into same device. IEEE 1588v2, ACR, Synch Ether, Clock over Microwave/xDSL

All the media in different network part, need the universal pwe3 pipes go through whole network, universal O&M Needs the complete synch techs together, not part of them.

DiffServ + Reservation mode

Easy to deploy, can change QoS policy flexibly as mobile operator’s requirement

Protect

Whole network seamless protection

A set of High Availability tech work together

Needs the complete synch techs together, not part of them.

Management

Hierarchical management

Universal NMS for all devices by pipe operator, mobile operator manage their own service inside tunnels

Backhaul makes up of thousands of sites, need high efficiency NMS tools, for device, service provisioning, trouble shooting, etc

Smoothly evolution for 3G, LTE, and FMC applications.

Device capacity, interface type, interface density, NMS, to support new services.

How to keep the future evolution, while no over invest for the current network.

E2E and Fast Deployment of Services Now:

Now: E2E and fast deployment of services. In the case of NBI service provisioning, only one interface is required.

Services are created in more than three sections in different NMSs. In the case of NBI service provisioning, more than three interfaces are required, and the service provisioning is slow.

No management interface is required in the bearer network (including the access network). The more the service layers, the more superior the model is. Before:

Several services are affected if a bearer service is faulty. Therefore, it is difficult to locate the root alarm. The affected services are traced by section. Therefore, many departments are involved in. Root alarm location is slow.
