IMS-10 Migration to IMS

IMS Evolution
Service Independent Network Layers
Network and Service Specific Service Silos
Service
Control
Access
Fixed
Enterprise
Wireless

• Creates shared and modular resources across
  multiple access methods
• Facilitates a unified user experience across
  multiple domains

• Services delivered as point solutions within each
  network silo
• Expensive and sustainable only for limited core
  services

4
IMS Standardization

• IMS was originally defined by the 3G.IP industry
  forum in 1999
• 3GPP adopted IMS as part of Release 5 (evolution
  from 2G to 3G networks)
• 3GPP2 based the CDMA2000 Multimedia Domain on
  3GPP IMS
• 3GPP Release 6 added interworking with WLAN
• 3GPP Release 7, working with TISPAN, added
  support for fixed networks

IMS Market Assessment

• Current Analysis, IMS Market Assessment, August
  7, 2007
• Ericsson 37 contracts for IMS deployment and 80
  trials
• NSN 30 commercial references and 50 trials
• Alcatel-Lucent 20 IMS full deployments
• Difficult to assess what has been deployed
• Some vendors claiming FMC, presence, instant
  messaging, POC and VoIP as IMS services
• Large portions of vendor roadmaps are based on
  standard that have yet to be completed

7
Market Assessment (continued)

• Heavy Reading, IMS Deployment Update Promises
  Challenges, July 2007
• IMS is running behind schedule
• Developments in mainstream Internet threaten the
  concept of IMS, such as Over the Top (OTT) video
  services putting pressure on telcos to come up
  with quick fixes
• The IMS promise of a better application creation
  and deployment environment could be undermined by
  new Web 2.0 tools that could be used to mashup
  telco and web services

Web Services for Telecom?

• Web Services
• Defined by W3C to request the execution of remote
  services
• XML / SOAP used for communications
• WSDL is the XML format to describe the service
  and usage
• UDDI is the protocol for publishing information
  about the Web Service
• RPC Web Services are distributed function calls
  
• Service Oriented Architecture (SOA) Web
  Services are message oriented

9
Mashups

• Mashups, also referred to as situational
  applications, were originally created in the
  browser by combining various widgets to form a
  service
• Server-based Mashups can be used to quickly offer
  new services built upon a set of Web Services
  made available through the UDDI
• BT has made its Web 2.0 Service Aggregation
  Environment (Web21C) commercially available to
  third party developers
• BT provided the following functionality Voice
  calling, conference calls, messaging,
  authentication, location, subscriber profile
  information, and contacts
• The functionality is higher level and does not
  require telco development knowledge
• The Web Services abstraction layer uses SIP and
  Parlay X which are hidden from the user

Internet Rhythm
Simon Beresford-Wylie, CEO designate of Nokia
Siemens
Declaring that the new company will encompass a
wide range of capabilities in various wireless
technologies including GSM, CDMA and WiMAX.,
Beresford-Wylie said, "We need to lose the
religion" and added that open standards will be
central to the roll-out of future Nokia Siemens
products..Simon Beresford-Wylie even went so
far as to suggest that previous determination by
many in the industry to create a proprietary and
closed version of the mobile Internet may have
been a mistake.He said, ""There is only one
Internet and I think we misunderstood that as an
industry. Services and content will come
predominantly from the Internet and we have to
understand that. Were moving from a world where
there was a telecom rhythm to one that has an
Internet rhythm,"

Removing the Garden Walls?

• Google sent a letter to the FCC indicating that
  open applications, devices, services and networks
  should be mandated for commercial spectrum, the
  FCC responded with a block of the 700Mhz spectrum
  that would be open to devices and applications

• Apple IPhone developed without operator influence
  offers WiFi to bypass the wireless network and as
  the advertising states offers not the watered
  down version of the Internet or the mobile
  version of the Internet or the kinda .. sorta..
  looks like the Internet .. Internet

• In February 2007, Skype is urging the US FCC to
  allow mobile subscribers to employ any hardware
  or software they choose as long as it does not
  harm the network. Mobile operators often block
  free internet services such as VoIP

Pragmatic IMS Deployment

• VDC in their research note titled Signaling
  Networks Are Dead. Long Live SS7!, July 2007,
  indicates that Service Providers do not believe
  there are compelling applications to justify the
  expense of moving to packetized networks.
  Operators are looking to add just enough to
  support revenue generating services. This implies
  that networks will become hybridized and service
  infrastructures will need to bridge the gaps.
• Current Analysis in their IMS Market Assessment
  dated August 7, 2007 indicates that IMS becomes a
  subset in a larger architectural framework to
  accommodate non-IMS traffic.

Hybrid Networks
Telco Web Services Mashup

• Abstraction provides Web Services Appropriate for
  each network
• 3rd Party Applications can use the Web Services
  to offer services in one network or across
  networks

Internet
UDDI Web Service Registry
3rd Party Domain
3rd Party Web Services Applications
Abstraction of functions into Web Services
Service Provider Domain
SS7 Based Network
IMS Based Network
Naked SIP Based Network

Future Role of IMS

• IMS is not, on its own, enough to enable an
  operator to deliver a rich set of
  revenue-generating services to the market. IMS is
  a good environment for creating or reimplementing
  a core set of specialist carrier-grade telco
  services, such as voice messaging, location, and
  presence. IMS gets these services off proprietary
  hardware and makes them easier and cheaper to
  maintain and enhance. While each of these core
  services has an intrinsic value, operators will
  make more money out of them in a next-generation
  IP world if they can blend their core service
  with other functions in innovative ways to create
  value-added services They need to make these
  SIP-based core services available for mashup.
