Slide 9

Evolution of SS7 Infrastructure (2)

• Top 3 growing SS7 elements– Signaling Gateways

– SMS Centers

– MSCs

• Main drivers– Migration to IP

– Signaling Gateways enable Carriers to add NG elements into their legacy SS7 networks

– Continuing expansion of SMS drives demand for SMSC and MSC

Why SS7 / SIGTRAN?

• Service Continuity

– New applications & networks need connectivity to existing

deployed circuit switched networks

• Amortized & Proven Technology

– SS7 network backbones still deployed in developing regions

• Wireless Subscriber Growth

– 2G / 3G networks largely deployed on SS7 backbones

• Cost Reduction

– Leveraging IP to reduce network OPEX and CAPEX

Scenarios for SIGTRAN Adoption

• New Generation of Traditional SS7 Equipment– Wireline and 2G Wireless Networks

– Upgrades and new deployments

– (internal) IP-based architecture• STP, SSP (Class 4/5, MSC), SCP, Service Node

– (external) IP environment• STP, SCP, HLR, SMS-C, SGSN

• Equipment for IP Networks– Wireline and Wireless (2G and 3G)

– New deployments

– NG Networks• IP MG, Softswitch

– 3G Wireless Networks• CS-MGW, MSC-Server, IM-MGW, MGCF

Slide 13

Key Growth Applications

• Value Added Services (VAS)

– SMS / MMS, Location, Presence, Ringtones, etc.

• Rebirth of IP Multimedia Subsystem (IMS)

– IMS critical for Next Gen Mobile

– Service Continuity

– Voice over LTE

Slide 14

The VAS Opportunity

• Mobile messaging = $102B market today

– SMS, MMS, E-Mail, IM

– Other VAS: gaming, music, TV, navigation,

search, marketing, stock trading, payment

• Source of ARPU growth in dev markets

– China MVAS over $22BM in 2009*

– India MVAS over $5B in 2009 – 2010*

• Low investment with high returns

– Leans on existing network infrastructure

– SS7 / SIGTRAN is the tap for VAS providers*Sources:

Slide 16

The IMS Opportunity• IMS Suffered the Hype Cycle

– A concept without an application

– Next generation mobile is the application

• Service Continuity over NGNM– VAS / IN porting to new mobile core / RAN

• LTE OneVoice Initiative– Specific IMS “profile” for delivering VoLTE

• GSMA -endorsed

– Support from almost every major operator worldwide• 3 Group, AT&T, Bell Canada, China Mobile,

NTTDoCoMo, TeliaSonera, Verizon, Vodafone …

SS7 / SIGTRAN Offerings

• Solutions for the low protocol layers– SS7 Boards

• Hardware + MTP1-2 protocols

– SIGTRAN Protocol Stacks• SCTP + Adaptation layers => to build Signaling Gateways

– Signaling Gateways• SS7 boards + SIGTRAN protocols + NIF + HA and management, in a fully-

packaged appliance

• Solutions for the upper layers (for SS7 and SIGTRAN)– Protocol Stacks

• MTP3 to User/Application Parts (ISUP, MAP, INAP, etc) => to build endpoints

– SS7 Board+Stack packages• Pre-integrated solutions

– Signaling Servers• Front-end units, including boards, protocols & interface to back-end systems

Slide 19

Trends in SS7 Technology Demand

• Off-The-Shelf SS7 solutions– Especially from Tier 1 TEMs

– With higher level of integration

• PCI-Express interface– But demand for PCI/PCI-X solutions still strong

• Low-Profile add-on cards– Market split between LP and FH

– Technical challenge for high-density cards

• Solutions for ATCA/µTCA systems (telco apps)– SS7 AdvancedMC modules (AMC)

– Demand for IP-based Host/Module interface

• Higher T1/E1 port density– 2 ports 4 ports now 8 ports per SS7 module

• Mixed Media Interface & SS7 solutions– e.g., with I-TDM (ATCA systems) or raw data mode (HMP

on rack-mount servers)
