IMS Motivation, Drivers and Opportunities (2) – Operators need to remain in Control q Key Portions of the operator’s Value Chain are under Attack: Converged World without Siemens IMS Closed and monolithic system Converged World with Siemens IMS Control Traditional Switching Services Control IP TDM IP Access IMS is the right tool to successfully defend your position Page 6 Nov-2006 Klaus Pulverer IMS in Mobile and Fixed Networks / © Siemens 2006
IMS Motivation, Drivers and Opportunities (3) – Key IMS Functions and Benefits q 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. Key IMS Service Support Functions: Terminal Application and Enabling Services Client Part Access- and Core Network e. g. SIP, RTP, HTTP API IMS Client Part Application Server Application Server (e. g. IPCentrex, Presence, etc) ISC IMS Network (CSCF, HSS, MGCF, MRF, etc. ) SIP API Gi, Mb, Go/Gx Access Network (Mobile , Wireless, Fixed) Access Page 7 Nov-2006 Klaus Pulverer • SIP Session Control • Service Control and Brokering • IMS User-Authentication • Subscription Handling • Qo. S/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) IMS in Mobile and Fixed Networks / © Siemens 2006
IMS Motivation, Drivers and Opportunities (4) – How does the IMS fit into the Operator network Service 1 1. IMS as Service Control Infrastructure: § § Service 2 ISC (SIP) enables the usage of Best-In-Class Application Servers SIP through IMS Service Control / Brokering. enables fast deployment through IMS Service Support Functions. § § § ISC (SIP) IMS User Profile: Þ If request method equals INVITE Service 1, Priority 1 Þ If request method equals MESSAGE Service 2, Priority 3 If request method equal INVITE Þ Service 3, Priority 6 s § 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. Other IMS or Vo. IP Network Mobile 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. PSTN (CDMA, GSM) IMS Fixed (e. g. x. DSL) Enterprise WLAN 3. IMS as Transit Routing / Interconnect Network: § § SIP S-CSCF 2.

Siemens FMC Reference Time Warner Cable demonstrates dual mode telephony München, Stamford, Connecticut, May 2, 2006 Solution concept Siemens Communications and Time Warner Cable recently showcased fully integrated fixed line, mobile FMC Services and Wi. Fi broadband technologies via the IP Multimedia (Vo. IP, Mobility) Subsystem (IMS) designed to deliver fixed mobile convergence (FMC). The demonstrations, which IMS 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 MTA and the provision of multimedia services is the Siemens IP Multimedia Subsystem (IMS@vantage). … Time Warner, one of the first cable network providers Cable Dual Mode worldwide to demonstrate IMS, plans to use Siemens Network Hand Set technology commercially to support a wide range of IP -based services.

Network operators may chose a stepwise introduction of FMC Fixed Step 1 • Gain experience • Enable network for FMC service delivery Step 2 • Early time-to-market with FMC services • Full reuse of equipment • Add few additional components for FMC Mobile Deploy Vo. IP / NGN applications in fixed nets Deploy IMS applications in mobile nets Add e. g. multiple terminal access to fixed network offer, add 2 G/3 G inter-working for video and data applications, add fixed-wireless access (e. g. WLAN), . . . Step 3 Single Brand • Address both fixed and mobile market with complete FMC offering for bundled fixed & mobile FMC services Operators that already deploy NGN in fixed, or IMS in mobile networks today are expected to be first to offer Fixed Mobile Converged services Page 19 Nov-2006 Klaus Pulverer IMS in Mobile and Fixed Networks / © Siemens 2006
