2 A Computação 78 (Minha turma!)

3 Prever Algo, Assusta ?

4 1G, 2G, 2.5G … A telefonia móvel de primeira geração ou 1G são analógicos, já que enviam a informação sobre ondas cuja forma varia de forma continua. A telefonia móvel de segunda geração (2G) não é um padrão ou um protocolo estabelecido, é uma forma de nomear a mudança de protocolos de telefonia móvel analógica para digital. 2,5G é a segunda e meia geração de padrões e tecnologias de telefonia móvel. É considerada o degrau de transição entre as tecnologias 2G e 3G, embora o termo "2,5G" tenha sido definido pela mídia, e não oficialmente pela União Internacional de Telecomunicações (UIT).

5 Mobile Network Evolution
Computing Evolution Mobile Network Evolution 2G/3G App Servers Internet RNC Transport Cellphones Gateway Transport (TDM/Pseudowire) Mainframe Terminals 4G App Servers Servers Carrier Ethernet Ethernet Internet PC Clients Smartphones Distributed Gateways

6 2G mobile networks were voice centric
Voice centric services Few services beyond Voice and SMS Simple mobile devices Devices geared towards voice, text-messaging and ringtones No real OS, no way to program the phone TDM backhaul Traffic backhauled using dedicated/leased circuits or SDH 5500 & 6300 GSM CDMA BSC MSC PSTN OCn n x DS3 / OCn 6300 6300 SMSC HLR n x DS3 SDH 5500 Voice Core TDM Backhaul BTS

7 2.5G added a data overlay to a voice-centric architecture
New Packet Data Services Introduction of new Packet Switched Data Core with Gateway nodes (SGSN/GGSN) modeled as “data MSC” First generation of Smartphones and PDAs WAP based Internet access Emergence of Blackberry for Enterprise Some multimedia capabilities (e.g., MMS) but no application download capability Increasing traffic load on the backhaul network BSC / RNC MSC PSTN OCn n x DS3 / OCn 6300 6300 SMSC n x DS3 SDH CS Voice Core 5500 TDM Backhaul HLR BTS Internet GPRS/EDGE/1xRTT SGSN / PDSN PS Data Core GGSN / Home Agent App Servers

8 3G, 4G ! 3G é a terceira geração de padrões e tecnologias de COMUNICAÇÃO móvel, substituindo o 2G. É baseado na família de normas da União Internacional de Telecomunicações (UIT), no âmbito do Programa Internacional de Telecomunicações Móveis (IMT-2000). A 4G estará baseada totalmente em IP sendo um sistema de sistemas e uma rede de redes, alcançando a convergência entre as redes de cabo e sem fio assim como computadores, dispositivos eletrônicos e tecnologias da informação para prover velocidades de acesso entre 100 Mbps em movimento e 5 Gbps em repouso, mantendo uma qualidade de serviço (QoS) de ponta a ponta (ponto-a-ponto) de alta segurança para permitir oferecer serviços de qualquer tipo, a qualquer momento e em qualquer lugar.

9 3G adds data capacity thus increasing backhaul traffic
Mobile Internet arrives WAP based Internet apps mature into Browser based Internet access Increased data traffic with corporate service Multimedia Smartphones Multimedia capable devices with cameras, music, video and ringtones Still no app downloads Pseudowire backhaul Migration to a more cost-effective packet transport to keep up with backhaul capacity demand 8600 and 8800 UMTS/HSPA/EVDO MSC PSTN SMSC CS Voice Core 8800/86xx 86xx Pseudo-Wire Backhaul RNC HLR NodeB 86xx Internet PS Data Core SGSN / PDSN GGSN / Home Agent App Servers

10 Smartphones drive higher speed 3G interfaces and Ethernet backhaul
OS-based Smartphones iPhone, Android change the landscape Application store downloads Emergence of mobile video Rapid growth in Internet traffic stresses the Core First generation GGSN products unable to scale Standalone DPI boxes Internet offload solutions Ethernet backhaul Node Bs with native Ethernet interfaces Carrier Ethernet transport in addition to Pseudowires 73xx, 7100 PSTN HSPA/HSPA+ MSC SMSC CS Voice Core 86xx Pseudo-Wire Backhaul RNC 86xx HLR NodeB 7100 8800/86xx IO Gwy Internet 73xx DPI Carrier Ethernet PS Data Core SGSN / PDSN GGSN / Home Agent App Servers

11 Evolution to All IP 4G Networks- Migration to a data-centric architecture
Collapsed Architecture eNodeB = NodeB + RNC Distributed intelligence in the Core Routers + S-Gwy Enhanced services support P-Gwy with DPI technology Subscriber/Application Analytics Application Delivery Control Policy Servers New monetization models More intelligent devices Kindle, Netbook, Tablets… Machine-to-Machine (M2M) MME/ PCRF S-Gwy Services Core S-Gwy IP/Ethernet DPI HSS S-Gwy P-Gwy Internet eNodeB PSTN

12 Mobile Internet Perfect Storm- A Unique Confluence of Factors
Smartphones & Application Stores The Personalized Web Mobile Broadband (4G + Carrier Ethernet)

13 Personalization of the Web is the fundamental driving force
Personality Oriented Community Oriented Information Oriented Portable, Personal Web Individual life-style focused Relevant and contextual Behavioral adaptation Demographics sensitive Semantic Web Web as the application platform Wildly “read-write” Web Participate and Share Social Commerce, Viral Marketing Web as the information portal Mostly “read only” Web Search driven Advertising

14 Increase in US Mobile Data Usage (1Q2008 -1Q2009)
34% 36% 32% Video Multimedia Messaging Internet 18% 18% 18% Text Messaging Downloads An average iPhone user consumes about 400 MB per month versus MB per month consumed by an average Smartphone user Nielsen iPhone Executive Overview, Q1 2009

15 AppStores are the driving engine for application proliferation on Smartphones
iPhone App downloads to date September 2009 2 Billion Downloads April 2009 1 Billion Downloads August 2008 60 M Downloads July 2008 (AppStore Launch)

16 Oportunidades no mercado e para o Bacharel de Computação (com slides do Dr. Vikram Saksena Tellabs Chief Technology Officer)

17 “Over-the-Top” Internet applications are stressing the network
Service Provider “Over-the-Top” model Applications delivered on a “best effort” basis Service Providers are only able to monetize subscriber access Over-the-Top apps unable to deliver good quality-of-experience to end users Application performance deteriorates as usage grows Application proliferation opens up threats from malware, viruses, and worms Application Providers Subs Access $$ “Best Effort” Over-the-Top

18 Role of DPI Technology in the Service Provider Network
Radio Network Knowledge Subscriber Knowledge Operator Policy Knowledge Content Knowledge Power to Control BTS & MS. Authority + + + + Cost Effective Optimization & Monetization using DPI Low Incremental Investment Simpler Network & Simpler Operation Upstream Resource Control, in addition to Downstream Extensive Content Usage Reporting Content Based Charging Models Content Based Dynamic QoS /QoE Mobile Advertising Internet Monetization Network Optimization

19 Internet Video is the Killer App
Traffic generated by YouTube and Hulu Petabytes/month Entire Internet Backbone traffic Video consumption over the Internet has successively penetrated consumer lives Source: Cisco Systems (Futurecom 2009 keynote)

20 The Three Waves of Internet Video Mobile Video expected to dominate
Internet video consumption on mobile handsets will far outpace the consumption on PCs and TVs Today’s mobile networks are not designed for mass consumption of video traffic from smartphones and netbooks Billions of Viewers 100’s of Millions of Viewers

21 Mobile Content Delivery
Mobile Content Server Carrier Mobile Content App Store Mobile Content Tailoring Content Owners Mobile CDN Overlay Click-zoom tiled navigation Media Chapterization Context and location based ad-insertion Keyword/Tag creation Social Mashups Intelligent caching for optimized delivery Mobile Packet Core Intelligent Mobile Cache Intelligent Mobile Cache Intelligent Mobile Cache

22 Mobile Security is increasing concern of consumers and network operators

23 Mobile Commerce is already here
Fast, safe, and affordable money transfer by phone (Kenya) Sellers post products using mobile phones. Buyers search by price, brand, location, etc. (Bangladesh)

24 Mobile Payments is a big market opportunity for Mobile Operators

25 Secure Mobile eCommerce Architecture with Intelligent Gateways
Mobile device is provisioned with consumer’s identity and payment information in the SIM Toolkit by Mobile Operator Intelligent Gateways with DPI technology can assist in mobile payment processing Reduce the cost of Mobile eCommerce Improve customer experience and security Generate new incremental revenue streams for Mobile Operators Mobile Gateway hosts mobile commerce app and API hooks Bank MNO Gateway Consumer MNO collects transaction fee Merchant receives electronic payment 6 Web 2.0 Micro-Merchandise (e.g. paid apps, game points, poker chips, VoIP minutes, digital gizmos, e-gifts, e-cards, pay-per-play gaming, photo prints, etc.) Online Merchants
