Course Contents

Review of the basics of mobile communications Overview on GSM, GPRS and EDGE UMTS networks, including

- network architecture,

- network elements,- protocols and- service aspects

Architecture, protocols and services of UMTS networks especially

- the radio access network and- the core network Evolution towards the 4th generation

- High-speed Packet Data (HSPA),- Long-term Evolution (LTE) and System Architecture Evolution (SAE)

Focus on network aspects rather than radio details

Course Objectives

Understand how UMTS networks work

Be able to navigate and understand UMTS standards

Understand why UMTS has been defined the way it is

Understanding of a real (non-trivial) integrated HW/SW system

Understand the evolution path towards and beyond UMTS

=> Understanding of the system from the system architects view

or: forget about the details as soon as you understand the whole

7/30/2019 01 UMTS Intro Ws11

6/45


Working Method

Study of a real Telco system with its specific problems

Identify and solve the identified problems instead of a general study

of abstract problems

Acquire a reasonable deep understanding of a highly complex system

Lots of discussion (hopefully)

Why UMTS?

GSM (2nd generat ion) :

Optimized for circuit-switched voice

High delay (180 ms round-trip)

Small band, inflexible assignment of

data rates Low data rates

Suboptimal use of radio resources

(spectral efficiency)

Complicated RF planning(layout of frequency usage)

Standard set by Europe

Globally available,but not planned as such

UMTS (3rd generat ion) :

Focus on packet-switched data

Lower latency

Flexible assignment of spectrum

with variable data rates Higher data rates for multimedia

services

Higher capacity of radio system

Simplified RF engineering (nofrequency planning)

Worldwide agreed standard

Worldwide roaming by design

What is 3GPP?

3GPP stands for 3rd

Generation Partnership Project 3GPP is a collaboration agreement, established in December 1998, toensure a worldwide acceptance of 3G W-CDMA/UMTS standards

It is a partnership of 6 regional SDOs (standard developmentorganization)

These SDOs take 3GPP specifications and transposethem to regional (Europe, NorthAmerica, Korea, Japan, China) standards

ITU references the regional standards

Version Released Info

Release 99 2000 Q1 Specified the first UMTS 3G networks, incorporating aCDMA air interface

Release 4 2001 Q2 Originally called the Release 2000 - added featuresincluding an all-IP Core Network

Release 5 2002 Q1 Introduced IMS and HSDPARelease 6 2004 Q4 Integrated operation with Wireless LAN networks and adds

HSUPA, MBMS, enhancements to IMS such as Pushto Talk over Cellular (PoC), GAN (UMA)

Release 7 2007 Q4 Focuses on decreasing latency, QoS and improvements

to real-time applications like VoIP. This specificationwill also focus on HSPA+ (High Speed Packet AccessEvolution), SIM high-speed protocol and contactlessfront-end interface (Near Field Communicationenabling operators to deliver contactless services likeMobile Payments), EDGE Evolution.

Release 8 2008 Q4 E-UTRA, All-IP Network (SAE). Release 8 constitutes arefactoring of UMTS as an entirely IP based fourth-generation network.

y ( )

2G (GSM): global digital personal communication system

2G+ (GSM+GPRS): introduction of packet-switched data

3G (UMTS): packet-switched data

CDMA-FDD/TDD

predominantly data communication focus on services and content all IP transport (3GPP R4): mobile, radio access network, core network SS7 signaling: AAA, mobility management, etc. QoS support

seamless service (global roaming) Enhanced packet data perfromance: HSDPA+HSUPA HSPA Common Ip-based service architecture (IMS)

4G: Integration of various radio technologies (satellite, broadcast, cellular, WLAN,

BAN) use of the optimal radio link (w.r.t. spectral efficiency, delay, throughput,

error rate, emission) IETF protocols for everything (all IP for transport and control)
