The Role of 3GPP Maintenance and evolution of Radio Technologies: GSM, GPRS, W-CDMA, UMTS, EDGE, HSPA and LTE Maintenance and evolution of the related work and Systems Architecture anizational Partners are Regional and National Standards Bodies ; 1 ? Over panies participate through their membership of one of the 6 Partners ? Plenary meetings each quarter (Next time is TSG#51, Kansas City, March 2011) ? Over 150 meetings (including Working Groups) in 2010 3GPP Specification Groups 2 3GPP Specification Groups 3 Spanning the Generations... GSM 1G Analog technology. Deployed in the 1980s. GSM 2G Digital Technology. First digital systems. Deployed in the 1990s. New services such as SMS and low-rate data. Primary technologies include IS-95 CDMA and GSM. 3G ITU ’ s IMT-2000 required 144 kbps mobile, 384 kbps pedestrian, 2 Mbps indoors Primary technologies include CDMA2000 1X/EVDO, WiMAX , and UMTS-HSPA. 4G ITU ’ s IMT-Advanced requirements include ability to operate in up to 40 MHz radio channels and with very high spectral efficiency. No technology meets requirements today. IEEE and LTE Advanced being designed to meet requirements. 3GPP Specified Radio Interfaces ? 2G radio: GSM, GPRS, EDGE ? 3G radio: WCDMA, HSPA, LTE ? 4G radio: LTE Advanced 3GPP work ? 2G/3G: GSM work ? 3G/4G: Evolved Packet Core (EPC) 3GPP Service Layer ? GSM services ? IP Multimedia Subsystem (IMS) ? Multimedia Telephony (MMTEL) ? Support of Messaging and other OMA functionality ? Emergency services and public warning ? Etc. 4 3GPP Evolution ? Radio Interfaces – Higher Data Throughput – Lower Latency – More Spectrum Flexibility – Improved CAPEX and OPEX ? IP work – Support of non-3GPP Accesses – Packet Only Support – Improved Security – Greater Device Diversity ? Service Layer – More IMS Applications (MBMS, PSS, mobile TV now IMS enabled) – Greater session continuity 5 Extracts from a video interview with Stephen Hayes, 3GPP SA Chairman, Ericsson Inc.
