T-Mobile@home Allows Mobile Calls with
Fixed-line Prices
• Customers make mobile calls to a fixed
network for 4 cents per minute
• Also works in a radius of up to two kilometers
• Users also receive a fixed-network telephone
number for a monthly charge of 4.95 Euros
• Outside the home zone, calls are forwarded to
the mobile phone number or mailbox
• Also available at special group rates
• Up to 5 T-Mobile customers can sign up
• Each family member/roommate gets a fixedline number and a common fixed-line number
• A similar service is available for smaller
businesses or branch offices
"We want to use T-Mobile@home to considerably
boost usage of mobile phones."

IP MPLS Core Principal Requirements
• What is the service availability requirement
Often quoted 5-9’s target equal to 1 minutes downtime per year
Non-Redundant Path

Redundant Path

CE
SDH
• What is the convergence requirement in event
of failure
For IP user data an outage of three seconds may be acceptable
For signalling an outage of 60 seconds may be acceptable if using
diverse paths (SCTP will recover)
For user voice an outage of less than 300–500ms may be required
If targeting SDH/SONET protection may require sub 50ms
27
IP MPLS Core Principal Requirements
• Physical network topology and structure
• Capacity planning and active monitoring
• Diffserv: per-hop congestion management
• Traffic engineering: avoid aggregation on
shortest path
Fast convergence protocols
ISIS, OSPF, LDP, BGP, VPN
Typically convergence in seconds
• MPLS TE FRR
Link, node, path protection
Target sub 50ms
Building Carrier Class Networks on IOS XR Benefits
HA, ISSU, Security, Scalability, Manageability, Flexibility
28
Business drivers to review RAN strategy
IP and Ethernet based RAN Aggregation
• OpEx reduction
RAN backhaul costs account for 20–30% (sometimes
much more) of total OpEx spend
• Investment protection
RAN accounts for 70% of CapEx spending
Introducing IP equipments improve the investment
protection by providing flexibility
• New services
Significant cost of rolling out a new service in the access
transmission network E.g. DCN on site, UMA, WiMAX…
Introduction of new data services drives an order of
magnitude increase in bandwidth
29
Technology drivers to review RAN strategy
IP and Ethernet based RAN Aggregation
• Increased coverage required for both 2G
and particularly 3G for indoor coverage
• Data rates to cell site accelerating with
operators planning on up to 8 or 16 E1 to a
cell site for:
EV-DO
HSDPA
WLAN
Wimax
30
Reduce transmission costs and deploy IP out to
the cell site with RAN-O and HSDPA offload

What Is IMS?
The IP Multimedia Subsystem
as defined by 3GPP release 5
for wireless networks
• Not Radio Technology Agnostic ( 2G/3G/Broadband Wireless )
• IMS is the first step to migrate mobile networks to All IP
• IMS is not an application itself but rather a framework allowing
to control applications
• First IMS applications are non real-time, e.g. Push-To-Talk
over Cellular (PoC)
IMS is a SIP Service Framework

Unlicensed mobile access (UMA)
UMA Specifications
Generic Access Network
Work item to formally
standardize UMA Specifications
Open, industry specifications for
extending mobile services over
broadband and unlicensed
For more see www.umatechnology.org
51
• Access: UMA provides access to
GSM and GPRS services over
unlicensed spectrum, including
802.11 and Bluetooth.
• Roaming: outside the range of
unlicensed wireless networks, the
UNC and handset facilitate roaming
to licensed outdoor network.
• Handover: On an active GSM voice
call or GPRS data session, that voice
call or data session can handover
between access networks with no
service interruption.
Source: www.umatechnology.org
• Transparency: All Services Roaming
and Handover are transparent to
subscriber.
UMA Technology is fully transitioned to 3GPP GAN Standard.
UNC also referred to as GANC.
52
Unlicensed Mobile Access (UMA )
Component Overview
Source: www.umatechnology.org
• UMA Network Controller: Integrates with existing operator voice (MSC) and data (SGSN)
components (via the A Interface and Gb Interface, respectively) and connects with UMA-enabled
handsets to provide alternative access to GSM voice and GPRS data services. It provides the
function of the BSC in a GSM/UMTS network.
• Security Gateway: Termination of IPSec from Mobile Subscriber, secure authentication of user, and
protection of mobile operator infrastructure.
• AAA Server: Secure authentication (via EAP-SIM or EAP-AKA) of Mobile Subscribers and
integration (Direct or Indirect) to Mobile Operator’s HLR.
• Access Point: WIFI or Bluetoorh wireless alternative access to mobile services.
• Dual Mode Handset: Client terminal with specific software allowing mobile access and dual radios.
