What is NGN?

- Mobile Network Evolution to NGN — 4 All rights reserved © 2005, Alcatel

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?� 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, China, Japan, USA�CDMA 1x EV-DV:

� NGN in Cs Domain with Separation of Control and User layers

� Backward compatible with CDMA2000 1xRTT

� Commercial service in 2005

Transport Bandwidth Efficiency (from R4 & beyond)

� 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
