  1. IP Multimedia Subsystem (IMS)Pushing New Services ITU/CoE Workshop Muscat 3 May 2004 Samer Qablawi Technical Solutions Consultant Siemens Middle East

  2. IMS - What are we talking about ? • IMS is a standardized IP control Domain for new MM services • IMS has been standardized by 3GPP in R5 (June 2002) • IMS enables peer to peermultimedia communication over Packet Networks • It uses SIP the protocol of choice for IP-based service control • It provides MM call control completing GPRS and UMTS infrastructure ITU/CoE Workshop 12/07/2001

  3. Why SIP is the Protocol of Choice for Multimedia Some SIP basics (Session Initiation Protocol) • SIP is standardised by IETF for VoIP and Multimedia • Succesor for ITUs H.323 (VoIP) • IP based Protocol (Sign. over UDP or TCP) • SIP is text based, very flexible and simple • Only 7 types of messages (methods) • Same session setup for all medias (different codecs) • SDP (session description protocol – capability negotiation) • Always included in SIP • Easy handling of different media streams (QoS) • 3GPP defined extensions for IETF SIP • Optimized Reference Architecture • SIP Header Extensions • Better QoS, Security and Charging features ITU/CoE Workshop 12/07/2001

  4. Comparison of IETF and 3GPP SIPTarget:The best of two worlds (IT and Telco) IETF IETF defines lots of protocols Internet paradigm Endpoint centric Security becomes more important Charging is of minor importance (flat rate) 3GPP Defines an architecture which uses protocols Operator paradigm Core network centric Security is one of the most important topics Charging is one of the most important topics IETF SIP 3GPP SIP Most of the SIPprotocol is generic SIP Only a few 3GPP specific headers remain ITU/CoE Workshop 12/07/2001

  5. Status of IMS in 3GPP • 3GPP Rel. 5 Specs were finished in 05/2002 • Stage 1 & 2 standards: requirements and functional architecture, basic features • Enhanced features --> Rel’6 • 3GPP Rel. 6 Specs were finished in 09/2003 • PSTN interworking: MGCF, MGW • WLAN access, Conferencing (MRF) 2003 2002 2004 Rel 5 Rel 6 Scheduling of 3GPP Releases ITU/CoE Workshop 12/07/2001

  6. Reduce OPEX and CAPEXIMS is an access-independent Service Delivery Platform • Enables Operators to have one homogeneous service platform for all packet based access networks (OPEX & CAPEX savings!) • Enables service interworking between different access technologies ITU/CoE Workshop 12/07/2001

  7. IMS enables new Types and Mixes of ServicesAnd this is what Users expect • Non-realtime and near-realtime services • Presence • Instant Messaging • Chat • Push to Talk (PoC) • Multimedia Messaging • Enhanced CLI • Push Services • Realtime services • Video telephony • “Rich” Voice (over IP) • Multimedia Conferencing • Video Audio/Streaming • Broadcasting IMS enables “new” types of services: And the Possibility of Combining: IMS also enables the ability to bundle realtime and non-realtime services: • Click to dial scenarios • Presence-enabled Conferencing • Mobile Gaming with Voice • Presence and Location based Push Services • Video streaming with integrated voice ITU/CoE Workshop 12/07/2001

  8. IMS – Pushing New ServicesNew multimedia services Communication • Push to talk over Cellular • Instant Messaging • Picture Chat • Multimedia Conferencing • Photo Share • Push-to-Flirt/-Show • Person-to-Person Gaming • Audio and Video Streaming Multi-Media Multi-User Multi-Session • Info Channel • Information Sharing • Interactive guidance • Collaborative working Entertainment Information ITU/CoE Workshop 12/07/2001

  9. From “Voice & Data” to “Multimedia”Impact on Average Revenue per User (ARPU) Multimedia New class of services 100 % Data ARPU, CAPEX Voice 0 % • Pure Voice ARPU is falling due to strong Competition • Data ARPU is climbing constantly • Multimedia ARPU will boost Mobile Revenues ITU/CoE Workshop 12/07/2001

  33. IMS – Pushing New Services Use cases of Picture Chat Business Users You are preparing a product presentation at your customers’ site. An important question is coming up… There is a “chat forum” where those of your colleagues occupied with the product share their knowledge. Ask them! The answer comes immediately including a photo of your product … Fast resolution of your problem, and your presentationwill be a success! Consumers Commuting to school. Every morning you sit in the train on your way to school and you use the time chatting with your friends Your buddy Brian could not make it through his maths homework. You have a great idea: You will just make a photo of your results and pass it to him! Source: Siemens ICM N M P, March 2003 ITU/CoE Workshop 12/07/2001

  34. Other Use Cases of IMS

  35. IMS – Pushing New Services Ideas of bundled PoC applications Enhancement of Push to talkover Cellular by bundling with • Presence / Location> All contacts at a glance with one single Buddy-List > Information of the availability of the contacts/buddies including terminal capabilities & preferences, moods and locations • Chatting/ Messaging> Creation of a common communication portal with text and voice based communication applications • Photo Shots & Video Streams> During a PoC conversation, instant picture shots or short video clips can be streamed to the other party, by simply pressing a button ITU/CoE Workshop 12/07/2001

  36. IMS – Pushing New Services Use cases of bundled PoC applications PoC_Chat PoC_Presence& Location During an ongoing PoC sessionyou want to inform one of your buddies about an important aspect - in private-:Invite him for a chat! You initiate a PoC session with your team asking for important information: one of them will answer by PoC_Call (voice based) and another by PoC_Chat (text based) You have a PoC Session with your buddies and during this session you want to show them where you are. Push-to-watch and pictures of you and your surrounding will instantly be streamed to your friend while talking! PoC_Push-to-Watch ITU/CoE Workshop 12/07/2001

  37. IMS – Pushing New ServicesShort description of Video Telephony Video Telephony • enables you to a more natural form of communication • gives you the opportunityto talk and to seeyour partner (& its surrounding) during your conversation inreal-time • has a camera function, which can be flexibly switched on/off • can be enhanced with Presence, Conferencing, Collaboration tools like document sharing, etc. 93% of communicationis what we see ITU/CoE Workshop 12/07/2001

  38. IMS – Pushing New Services Use cases of Video Telephony Share a moment with family/friends: “Hi Brian, I would like to show you where I am right now! Families living apart – Dad is on a lot of business trips, but still wants to see his kids; and they want to see, where he is. Surveillance: Baby-phone: “How is my baby doing?” On vacation: “Is everything o.k. at home?” Remote Diagnostics for medicine, technical experts, car repair, etc. ITU/CoE Workshop 12/07/2001

  39. IMS – Pushing New Services Short description of Information Sharing Display Sharing> Share the view: You able to see what is on my screen> With two options: You can/ cannot save,what you see. Remote Guidance > Guide through it: You will guide me through the information, which is on my (and also your) screen. Application Sharing > Joint work: Both parties work on one file simultaneously. Both parties are able to modify the file. Bundlingwith other applications > Multi-Service Bundling: Look on it! Work on it! Talk about it! ITU/CoE Workshop 12/07/2001

  40. IMS – Pushing New Services Use cases of Information Sharing Display Sharing ‘OK, I will show you a photo of my new baby born. Let’s have a look at my screen …’ ‘Just take a look on the last email I have received …’ You told me, how easy it is to make a reservation via mobile. But I can’t make it: You guide me through the service – Remotely, because you are not in Cannes right now. RemoteGuidance You are sitting at the airportwaiting for your flight to take off and have been working on a presentation. You would like to get a feedback from a colleague in the office. Show him your slides! Jointlylooking at your slides, you can discuss which aspects you could change. Application Sharing bundled with voice application ITU/CoE Workshop 12/07/2001

  41. Conclusions for IMS HSS MRF • Todays mobile networks lack some functionalities  This gap is filled by IMS • IMS provides a 3GPP standardised infrastructure for an efficient deployment of numerous multimedia services • IMS enables peer2peer communication in the ps domain • IMS provides an efficient multimedia oriented session control • IMS keeps the value chain within operator’s network • IMS comes with an state-of-the-art service creation concept • IMS leverages the process of finding the UMTS killer application • One IMS client supports all IMS services ITU/CoE Workshop 12/07/2001

  42. IMS is reality … and we are looking into a bright future ITU/CoE Workshop 12/07/2001
