- 1. 1 3GPP TSG SAChairman 3GPP TSG SA Chairman Stephen Hayes Stephen Hayes 3GPP presentation on Services Evolution Moscow, September 2008
- 2. 2 3GPP Directions Radio NetworkCore Network •Faster Data rates •Decreased Latency •High Cell Edge Throughput •Spectrum Flexibility •Access independence for services •Standardized multimedia services •Mobility and IP interworking for all accesses FASTER Wider Scope
- 3. 3 Broadband FMC Any service •Ranging from gaming to sports and live entertainment • From high secure data communication to video chats Anywhere • Ranging from the big cities to the countryside • From the office desk to the great outdoors Any device • Ranging from the mobile to the multimedia PC • From the gaming console to the HDTV
- 4. 4 Broadband Accesses They comein many flavors xDSL Fiber (PON & P2P) Fiber/VDSL2 Fixed Wireless HSPA/LTE Satellite/Terrestrial Unlicensed (WiFi, etc) Others Cable (DOCSIS2 3) Fixed access Fixed/nomadic wireless Mobile access WCDMA/HSPA LTE CDMA2000 EVDO GSM/EDGE The borderline between fixed and mobile is getting less clear Mobile WiMax Others

- 9. 9 IMS/Common IMS • IMS –Session Control based on SIP/SDP – Authentication/Authorization based on Diameter – Extensions for Operator Needs • Resource Control/QoS • Charging • Security and Identification • Roaming • Regulatory (emergency call, lawful intercept,etc.) – Access Independent – Standardized Multimedia Suite Defined in 3GPP – Many operators have already deployed IMS for FMC • Common IMS – Extensions to IMS to meet requirements of different industry segments • Regulatory • Legacy • Different Business Models
- 10. 10 Multimedia Telephony Service •Multiple Simultaneous Media Streams – Voice – Text – Video – File Transfer – Video/Photo/Audio Sharing • Multimedia analogs of traditional PSTN supplementary services – Originating Identification Presentation (OIP) – Originating Identification Restriction (OIR) – Terminating Identification Presentation (TIP) – Terminating Identification Restriction (TIR) – Malicious Communication IDentification (MCID) – Anonymous Communication Rejection (ACR) – Communication Diversion (CDIV) – Communication Waiting (CW) – Communication Hold (HOLD) – Communication Barring (CB) – Completion of Communications to Busy Subscriber (CCBS) – Message Waiting Indication (MWI) – Conference (CONF) – Advice Of Charge (AOC) – Explicit Communication Transfer (ECT) – Reverse charging – Closed User Group (CUG) – Three-Party (3PTY)
