Niklas Blum Fraunhofer FOKUS 2006 IMS as NGN SDP Motivation • IP network connectivity is given (GPRS/UMTS, WLAN, Wi. Max, DSL, . . . ) • Main IMS idea: Use IP network for both – Circuit-switched-like, synchronous, Qo. S enabled multimedia services – Packet data multimedia services (like in the internet) • Standards scope: Provide a minimum set of interfaces (common denominator) for interoperability (Plug&Play of applications) • Reuse as much as possible standard IP protocols for session control, management and bearer transport (SIP, AAA, RTP) • BUT: What is the difference to the internet / Vo. IP? IMS should provide a controlled, secure internet service environment with Qo. S and charging capabilities • Take into account existing mobility infrastructure and mobile services to provide an evolution story Combinational services • Today IMS is extended to cope with fixed access networks as well IMS as common SDP for Fixed Mobile Convergence! 3

Niklas Blum Fraunhofer FOKUS 2006 The Drama of todays Service Space • There is broad spectrum of technologies one has to understand in the context of Fixed Mobile Convergence and Next Generation Networks (telecoms, internet, IT) • The converged network value chain is getting complex (network, portal, content, etc. ) • Big players try to cover all major layers resulting in non-optimum offers which are not appreciated • Innovation in the telecoms field is driven by technology push • Access to the new technologies is quite complicated for small players and most particular for application providers • This is too expensive and often technology is promoted to early with raising wrong expectations resulting in frustration • A technology pull model in which technology introduction will be driven by concrete demand specific applications • This means the applications developers need early access to the technologies Open testbeds are needed 4

Niklas Blum Fraunhofer FOKUS 2006 Network Generation Network Vision • Mobility and Qo. S enabled IP core • Simplified service provisioning independent of access UMTS CDMA WLAN Wi. Max POTS/ GSM EDGE Common Applications and Services IP – Network mobility-enabled ISDN Wireline x. DSL other 5

Niklas Blum Fraunhofer FOKUS 2006 IMS as NGN SDP Motivation • IP network connectivity is given (GPRS, UMTS, WLAN, DSL, etc. ) • Use IP network for CS-like, synchronous, Qo. S enabled MM services • Enable an open set of innovative services (like in the internet) • Provide a controlled, secure service environment with Qo. S and charging capabilities • Provide a minimum set of interfaces (common denominator) for interoperability • Reuse as much as possible standard IP protocols for session control, management and bearer transport (SIP, AAA, RTP) • Extend these protocols to achieve security and managebility • Take into account existing mobility services and infrastructure 7

Niklas Blum Fraunhofer FOKUS 2006 Communications Landscape Is Changing The IT Community Rich in Applications and Creativity The Telecom Community Rich in Networks and Connectivity Technical Convergence OSA, Parlay and JAIN are examples of emerging Technology Standards that facilitate the convergence of the IT and Telecom communities 8

Niklas Blum Fraunhofer FOKUS 2006 3 GPP IP Multimedia Subsystem (IMS) • The IMS has been originally defined by the 3 rd Generation Partnership Project (3 GPP) as part of UMTS Release 5 / IMT 2000 – Extensions have been made in release 6 to adapt to real world (e. g. IPv 4) • 3 GPP 2 has adopted the IMS architecture on top of Multimedia Domain (MMD) • ETSI TISPAN is defining Next Generation Network SDP for all IP Networks based on IMS • Open Mobile Alliance (OMA) defines IMS Enablers & Services • The IMS represents an overlay network on top of GPRS networks and provides an all IP service delivery environment for mobile multmedia service provision (Vo. IP, Videotelephony, MM Conferencing, Mobile Content, etc. ) • The IMS is based on the IP world protocols, namely – – – SIP (Session Initiation Protocol) for Session Control, and Diameter for AAA (Authentication, Authorisation & Accounting) plus many others, i. e. SDP, RTCP, MGCP, etc. 9

Niklas Blum Fraunhofer FOKUS 2006 Push to Talk over Cellular (Po. C) • Po. C is standardised in the Open Mobile Alliance (OMA), Rel. 1 in 2005 • First specification process was initiated by the MENSA (Motorola, Ericsson, Nokia, Siemens, AT&T Wireless) consortium in 2002, 2003 • Po. C is a way of communication that uses half-duplex connections – – similar to walkie-talkie functionality allows to deliver a talk burst to a collection of users • Po. C client is (usually) in the handset as a soft client • Po. C server has ambiguous functionality: It manages both the signalling and also the media – By definition the Po. C server is acting as a SIP AS, connecting to IMS CN through the ISC interface • OMA Po. C does not consider access network issues (any access network can be used) • OMA Po. C requires the XML Document Management (XDM) enabler for group session configuration • OMA Po. C may use OMA XDMS architecture for presence as a presence enabler • Dedicated floor control messages are used to grant access to the floor to ensure semi-duplex paradigm 17

Niklas Blum Fraunhofer FOKUS 2006 From PTT to Community-Support • Po. C/PTT basically defines a specific service based on generic enablers (Presence, GLMS/XDMS, FOTA) • Infact Po. C/PTT could be regarded as a specific instantiation of a group communication framework • Making money with Po. C/PTT is unclear • Making money with SMS and voice calls is clear • Idea: • Reuse Po. C/PTT enablers for other communication services as well Integrated Presence driven IM, email, SMS, MMS, Vo. IP, CS-Calls, Video calls, etc. • Provide group communication to those who really need it well established Communities (Sports, Work, health, fun) will appreciate this! 19

Niklas Blum Fraunhofer FOKUS 2006 From PTT to Community-Support • But how to link these enablers with the legacy services – IMS is defined for all-IP! • Solution 1: implement PTT on top of OSA/Parlay APIs – Provides reuse of enablers for different network services • Solution 2: Provide third party interfaces with OSA/Parlay APIs (i. e. Parlay X) to the existing communities 20

Niklas Blum Fraunhofer FOKUS 2006 Summary • Telecommunications is at crossroads • The internet and related IP-based technologies will change dramatically the service world • IMS is in the center of converging networks • IMS is a service platform framework harmonising the architectural thinking of different actors and forms the basis for NGN realisation • IMS as platform is not defining services (OMA does it partially by defining service enablers) – IMS killer applications remain unclear – but without IMS classic fixed and mobile operators will have a hard time competing against internet services and emerging VNOs • OSA/Parlay and Parlay. X can act as the bridge towards the internet developer community and 3 rd party service providers • More information at www. fokus. fraunhofer. de/ims 32
