  1. IMS in Mobile and Fixed Networks Klaus Pulverer ICT Workshop, Brasilia November 2006

  2. End-user have High Expectations for Seamless Communication… • Convenience • Same look & feel on various devices leads to higher acceptance and usage • Availability • control and manage more effectively when and how to be contacted Freedom of choice Don't care about the network Customer Expectations • any access,any device,any location,any time • Independency Enjoy new services • Demand for individual,lively & colorful communication services • Personalized services Ease of use End-users go for the most attractive service bundle

  3. IMS in Mobile and Fixed NetworksContent • IMS motivation • Convergence: Mobility and new services • Migration: how to get there

  5. IMS Motivation, Drivers and Opportunities (1) – New Revenue Sources are needed • Goal: ubiquitous, personalized, seamless multimedia communications and entertainment. … Converged Address Book,Messaging, etc. Video Telephony and Entertainment Voice over IP and Residential Services Converged CentrexServices CDMA/WLAN Call Continuity with Dual-Mode Handsets Revenue Market introduction of attractive services will lead to increased revenue and customer satisfaction. Declining voice revenues Time

  6. IMS Motivation, Drivers and Opportunities (2) –Operators need to remain in Control • Key Portions of the operator’s Value Chain are under Attack: Converged Worldwith Siemens IMS Converged Worldwithout Siemens IMS Closed and monolithic system Control Traditional Switching Services Control IP TDM IP Access Access Access IMS is the right tool to successfully defend your position

  7. Key IMS Service Support Functions: • SIP Session Control • Service Control and Brokering • IMS User-Authentication • Subscription Handling • QoS/Media Authorization • Signaling Compression • Routing/Addressing Support • PSTN/CS Interworking Support • Mobility Management Support • Conferencing Support • Charging Support and Charging Correlation Support • Feature Interaction Support • Regulatory Service Support (e.g. Interception, Emergency Calls, Number Portability) Terminal Access- and Core Network Application Server Application Server Application Server Application Server Application and Enabling Services Client Part Application Server (e.g. IP-Centrex, Presence, etc) e.g. SIP, RTP, HTTP API ISC IMS Client Part IMS Network (CSCF, HSS, MGCF, MRF, etc.) SIP API Gi, Mb, Go/Gx Access Access Network (Mobile , Wireless, Fixed) IMS Motivation, Drivers and Opportunities (3) – Key IMS Functions and Benefits • Increase control and profitability through a common IMS based Service Infrastructure: • The IMS is an open Service Infrastructure providing Service Support Functions that assist the development/control/integration of services. • IMS is not just a simple SIP-Proxy.

Service 1 Service 2 Service 3 ISC (SIP) ISC (SIP) SIP SIP IMS User Profile: Þ § If request method equals INVITE Service 1, Priority 1 SIP SIP Þ § If request method equals MESSAGE Service 2, Priority 3 Other IMS or VoIP Network Þ § If request method equal s INVITE Service 3, Priority 6 S - CSCF Mobile(CDMA, GSM) Mobile(CDMA, GSM) PSTN IMS Fixed (e.g. xDSL) Enterprise WLAN PSTN PSTN IMS PSTN Enterprise IMS Motivation, Drivers and Opportunities (4) – How does the IMS fit into the Operator network • IMS as Service Control Infrastructure: • enables the usage of Best-In-Class Application Servers through IMS Service Control / Brokering. • enables fast deployment through IMS Service Support Functions. • IMS as Core of the FMC Network: • enables access agnostic user experience and service transparency through wireless – wireline integration as e.g. needed in Hosted Enterprise deployments with Mobile-/Fixed- IP-Centrex. • enables operator interoperability and vendor interoperability through IMS standard interfaces. • IMS as Transit Routing / Interconnect Network: • enables the support of PSTN Emulation/Simulation. • addresses the Interconnect Market by enabling the support of IP Peering with User-specific Services for Transit Calls. The Siemens IMS supports all three scenarios

  9. SIP SIP HSS HLR IMS Motivation, Drivers and Opportunities (5) – Siemens IMS Strategy: IMS based Service Consolidation • One IMS based Service Infrastructure for: 1) Fixed Market, 2) Mobile Market, 3) (Hosted) Enterprise Market, 4) Transit/Interconnect Market will provide a Converged Communication World. • IMS as central core in 3GPP (Mobile, WLAN), TISPAN (Fixed), PacketCable2.0 (Cable) ensures interoperability and long term investment protection.

  15. SIP Siemens FMC ReferenceTime Warner Cable demonstrates dual mode telephony Solution concept München, Stamford, Connecticut,May 2, 2006 Siemens Communications and Time Warner Cable recently showcased fully integrated fixed line, mobile and WiFi broadband technologies via the IP Multimedia Subsystem (IMS) designed to deliver fixed mobile convergence (FMC). The demonstrations, which recently took place at Time Warner’s U.S. facility, highlighted the practical value for network operators of adopting Siemens’ IMS solutions and also showed how consumers can enjoy shared multimedia applications, entertainment features and communication sessions – all on the basis of converged solutions. …The technical platform for simple network handover and the provision of multimedia services is the Siemens IP Multimedia Subsystem (IMS@vantage). …Time Warner, one of the first cable network providers worldwide to demonstrate IMS, plans to use Siemens technology commercially to support a wide range of IP-based services.

  19. Network operators may chose a stepwise introduction of FMC Fixed Mobile Deploy VoIP / NGN applications in fixed nets Deploy IMS applications in mobile nets Step 1 • Gain experience • Enable network for FMC service delivery Add e.g. multiple terminal access to fixed network offer, add 2G/3G inter-working for video and data applications, add fixed-wireless access (e.g. WLAN), ... Step 2 • Early time-to-market with FMC services • Full reuse of equipment • Add few additional components for FMC Single Brand for bundled fixed & mobile FMC services Step 3 • Address both fixed and mobile market with complete FMC offering Operators that already deploy NGN in fixed, or IMS in mobile networks today are expected to be first to offer Fixed Mobile Converged services
