Use pursuant to company instruction 2

An IP multimedia and telephony core network

IMS is defined by 3GPP and 3GPP2 standards organizations

Based on IETF (internet) protocols

IMS applies equally well to wireless and wireline access carriers

– Supports IP to IP sessions over cable, DSL, 802.16, 802.11, CDMA packet data, GSM/EDGE/UMTS packet data, etc.

Equivalent to IP telephony systems being invented by some operators such as Verizon wireline. Both use IETF protocols. But IMS is standards-based.

What is IMS?

Business Implications: IMS cost-effectively enables lifestyle-targeted, blended services, positioning the operator to “own” the subscriber regardless of how they access the network

CAW



IMS - Industry Standard Architecture

IMS (IP Multimedia Subsystem) is:

Same framework for any kind of access (wireless or wireline) and any kind of traffic – VoIP, data, multimedia, supporting multiple clients and endpoints

Defined with Open Standard Interfaces -> 3GPP and 3GPP2, and based on IETF Protocols (SIP, VoIP, RTP, ...)

Standardized interfaces between applications, core & transport network layers, and back-office systems

Provides coordination or synchronization as required

Capable of Interworking with PSTN and Legacy IN Based Services (8xx, LNP, etc)

CAW



IMS Benefits

Common contacts across services– Enterprise & personal lists, enhanced

with capability indicators

Multimedia enriched communication

– Multiumedia information can be sent and received during a voice call

Voice enriched data applications

Predictable service interactions– Operator can set defaults for service

interactions to maximize ease of use and service quality;

– Subscribers can set policies on how they want their services handled,

Retain ownership of the subscriber – Provide better quality services than IP

today avoid migration of value to the client device

Differentiate services from competition and sell more services

– Choose the applications to create blended services;

– Home control same services even when the user roams

More cost-effectively deliver high value, new lifestyle services to market

– Minimize client-server airlink traffic by leveraging IMS network information

– Reduce costs of new services through common applications infrastructure

Reduced OPEX– Centralised data and common functions– Standardised QoS, roaming, billing

For End-Users For Service Providers

Building Blocks for Lifestyle Targeted Blended Services

CAW



The Real Opportunity: Blended Services,Not Just Bundled Services

• Everyone is bundling to retain subscribers.

• Bundling simplifies billing - does not reduce other OpEx.

Bundling alone will not create lasting incremental value.

Bundling drives commoditization and price erosion

Bundling alone will only shrink the customer’s spending as value is eroded

Seamless blending of voice (wireline and wireless), data and video services required to realize full revenue potential

Providers with scale and wireline + wireless networks will have an advantage

Providers with a strong convergence story/vision will flourish and dominate

IMS is a Services Architecturefor Cable OperatorsMobility is an essential component of the consumer &

business offers– ILECs are implementing “grand-slam” bundles – MSOs must match

– IMS and IP architectures enable greater ARPU, margin, stickiness and overall operational efficiency

Competitive advantage can be achieved by adoption of a common network and application platform– Economies and new services potential

are better with cable + cellular

– Content and Applications (not price)become the differentiator

– Unique content-rich services can leadthe consumer market & take share

– Will protect against bundle-churn andexcessive bundle discounting

An IMS Services Architecture allows a Service Provider to “own” its subscribers even when using elements of other operators’ networks

• Cable services today are vertically oriented

• Beyond traditional video, IP provides a common logical transport layer for data, IP video, voice, broadband multimedia and converged services

• NCS supports narrowband VoIP

• SIP supports a wide variety of services ranging from narrowband VoIP to converged services

PacketCable 1.xThe Softswitch Model

Designed for voice, not multimedia

Optimized for legacy endpoints

Focused on primary-line features, not multimedia

Separates media from control, but not services from session – limited opportunity for OPEX savings

Proprietary application server interfaces- difficult to add new 3rd party services

Does not address convergence with wireless
