What is NGN?
What is NGN?
NGN: Next Generation Networks
* Separation of
* Access Layer
* Transport Layer
* Control Layer
* Service Layer
* with Control & Transport Layers being shared by
*the different Access Type (RAN, Fixed…)
*and Service Layers
* with Packet (ATM, IP) Transport converging toward IP transport
* for provision of Multimedia Services (Real Time, Presence, Messaging, Voice, Video, Data...)

How NGN applies in Mobile Networks?
How NGN Applies in Mobile Networks?
* UMTS R99:
* Largely derived from GSM
* Last non-NGN Release
* Features content functionally frozen 12/2000
* Still Change Requests (Mobile Test Plan to be finalised by 2H04)
*UMTS R4:
* NGN in Cs Domain with Separation of Control and User layers
* Introduction of Server & MGW
* Introduction of ATM and IP transport instead of TDM
* Standard completed in March 2001 but still essential CR (TrFO...)
*UMTS R5:
* NGN for IMS
* Introduction of MM Call Server with SIP Call Control Protocol
* Standard Content frozen in June 2003 (many CR to come)

How NGN Applies in Mobile Networks?
* CDMA 1x RTT:
* Extended radio technology from IS95
* Last non-NGN Release
* Release 0 in commercial service since Oct 2000
* New overlay Packet Data Serving Node
*CDMA 1x EV-DO:
* Hybrid CDMA+TDMA technologies for bursty applications (High Speed Data)
* Requires a separate carrier (1.25MHz), mainly deployed for hot zones.
* Could be developed independent of IS95/1xRTT. (No MSC/VLR needed)
* Commercial service in SK, US since 2002
*CDMA 1x EV-DV:
* NGN in Cs Domain with Separation of Control and User layers
* Backward compatible with CDMA2000 1xRTT
* Commercial service in 2005

* ATM AAL2:
the most efficient for both Voice and 64kb/s Data
* POS:
the most efficient of the IP transport
* 64kb/s Data: Packet transport brings degradation
but data traffic on Cs should be low w/r to voice traffic
