3GPP Directions
FASTER
•Decreased
Latency
•High Cell Edge
Throughput
•Spectrum
Flexibility
Radio Network
•Access independence for
services
•Standardized multimedia
services
•Mobility and IP interworking
for all accesses
Wider Scope
•Faster Data
rates
Core Network
2
Broadband FMC
Any service
• Ranging from gaming to sports
and live entertainment
• From high secure data
communication to video chats
Any device
• Ranging from the mobile to the
multimedia PC
• From the gaming console to the
HDTV
Anywhere
• Ranging from the big cities to
the countryside
• From the office desk to the great
outdoors

Broadband Accesses
They come in many flavors
Fixed
access
Fixed/nomadic
wireless
Fixed Wireless
HSPA/LTE
xDSL
Fiber (PON & P2P)
Fiber/VDSL2
Cable (DOCSIS2
Satellite/Terrestrial

Unlicensed
(WiFi, etc)
Others
Mobile
access
GSM/EDGE
WCDMA/HSPA
LTE
CDMA2000

IMS/Common IMS
•
IMS developed as part of 3GPP Rel 5 as an application development
environment
–
–
–
•
IMS retargeted in Rel 7 for telephony replacement
–
–
–
•
Encourage new applications to use environment
Greater operator policing than native SIP/SDP
Home control allowing customization
Standardized multimedia suite developed
Optimizations to improve performance
Access independence
Common IMS specified in Rel 8
–
Integration of IMS variants and requirements from 3GPP2, TISPAN, and Cablelabs

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

Summary
• 3GPP is committed to Mobile Broadband
• 3GPP is committed to FMC
• Two complementary paths to broadband
FMC
– Common Service Platform (Common IMS)
– Multi-Access Packet Core (EPC)
