How telecoms look 3Se$ng the Context
First telephone demonstrated in around 1875
First personal computers emerged in the early 1960s (Apple / IBM?) Limited funcDonality, no network connecDon
First mobile phone appeared in 1973, was the size of a house brick and could only do analogue voice
In the beginning….
How telecoms look 4Se$ng the Context
Home phones were made out of “bakelite” and were used for voice only
Computers increased in processing power and funcDonality and connected to the network via a simple 64kb/s modem
Mobile phones shrank drasDcally, and could do voice and limited data, (9.6kbps and SMS)
Yesterday….
How telecoms look 5Se$ng the Context
Home phones are frequently cordless (DECT), with advance network funcDons (caller ID, call waiDng …)
Computers have greatly increased processing power / mulDmedia funcDonal and connect to the Internet via xSDL/cable/Fiber (up to 10Gbps)
Mobile phones have increased funcDons, (Music/Photo/HD Video), and the networks (LTE/UMTS/GPRS) support faster data rates (+100 Mb/s)

Market CompeDDon
Market compeOOon is increasing
Incumbents squeeze incumbents (internaDonally)
Mobile operators squeeze fixed operators
Fixed operators fight back with Wi-‐Fi soluDons
Mobile operators are squeezed by Wi-‐Fi
New players (MVNOs, Google, Skype), squeeze everyone
Core revenue (voice) is saturated and profit declining
Whilst voice revenue stagnates, Data revenue increases
Network costs are too high, and old equipment need replacing
Networks are complex, hard to scale and interoperate
Operators are Oed to vendors for dedicated technologies
Roll-‐out Dme for new services is too long
Also customers are pushing for more innovaDve services
9Se$ng the Context
Market CompeDDon
Fixed line usage is reducing dramaDcally for “classical” services
Mobile use is increasing steadily even though penetraDon is already high.
Broadband Internet deployment shows a rapid growth trend.

Market CompeDDon
OpOon 1: SOck head in sand and ignore the storm
ConDnue down the same path, upgrade exisDng kit
OpOon 2: Evolve
simplify the network (reduce complexity and cost)
become access independent (mobile / fixed)
offer new services quickly and on demand
concentrate on content and services
12Se$ng the Context
Operators must evolve or become extinct
Market CompeDDon
Most operators seem to have chosen OpOon 2: Evolve with Next GeneraOon Networks:
MigraDon path to an IP based network, whilst maintaining exisDng services
Reduce COSTS (CAPEX and OPEX), and increase ROI, (RETURN ON INVESTMENT)
Common foundaDon for both fixed, mobile and enterprise services
Quick creaDon and deployment of innovaDve new blended services
Flexible dimensioning
Advanced centralised network control
Anract third party service providers without loosing control of the network
Open interfaces allow vendor independence
13Se$ng the Context
Operators fight back with Next Gen. Networks
Convergence
A technology that is revoluOonising the telecoms world:
Convergence of the “Market”
Convergence of the “Service”
Convergence of the “Device / Terminal”
Convergence of the “Network”
14Se$ng the Context
What is Convergence?
Convergence
Convergence of the Market
Commercial Convergence
Bundling of fixed, mobile and data subscripDons
Subscriber can access fixed, mobile, and internet services from a single operator
Ideally this would allow for one provider and one bill for mulOple service (unified billing)

Convergence
Convergence of the Market
France Telecoms’ mobile, fixed broadband, IPTV, and business services in France and the U.K. took the Orange SA brand in 2006.
Portugal Telecom’s mobile (TMN), fixed broadband, IPTV (MEO) and business services took the MEO brand.
Portuguese OpDmus (mobile), Clix (residenDal IPTV and fixed broadband), Novis (business services and networks) , ZON (cable broadband, satellite, TV and IPTV) and Lusomundo (contents) fused to NOS SA brand.
Everything Everywhere is the company that runs the Orange and T-‐Mobile brands in the UK, and launched in 2012 its superfast 4G (LTE) brand – EE.

Convergence
Convergence of Services
Subscribers access same services regardless of whether they are using a fixed or mobile connecOon
MMS (mulDmedia messaging) on a fixed or mobile phone
Presence services on a computer or mobile device
Email access on a computer, mobile or fixed phone
Voice service (VoIP) on fixed, mobile device or computer
TV service on TV sets, mobile devices, computers

Convergence of Devices
One device may integrate various access types
This may include Mobile (GPRS or 3G or 4G) enabled with wireless technologies (Bluetooth and/or WLAN 802.11 b/g/an…)
Also may refer to “one device does all” with enhanced funcDons such as music/photo/data/video/voice/messages…
18Se$ng the Context
What is Convergence?
Convergence
Replace many “stove-‐pipe” single service networks with a single “converged” network:
Remove mulDple disparate OSS (OperaDons Support Systems):Order Management, Billing, Customer Care, Provisioning, AcDvaDon, etc.
Avoid “interworking” issues
Create new opportuniDes (services) and faster service enablement
Provisioning Intelligence layer and ApplicaDon Plauorms
23Se$ng the Context
Rationale
Convergence
Challenge: Maintaining TradiOonal services over NGN:
PSTN/ISDN EmulaOon
Provide PSTN/ISDN-‐like service capabiliDes using session control over IP interfaces and infrastructure
Emulate a PSTN/ISDN network from the point of view of legacy terminals
PSTN/ISDN SimulaOon
Provides PSTN/ISDN service capabiliDes and interfaces using adaptaDon to an IP infrastructure
The provision of PSTN/ISDN-‐like services to advanced terminals (IP-‐phones) or IP-‐interfaces.
