UMTS Architecture

• UMTS: Universal

Mobile

Telecommunications

System

• PLMN: Public Land

Mobile Network

• UTRAN: UMTS

Terrestrial Radio

Access Networks

• UE: User Equipment

• ME: Mobile

UTRAN Architecture

• RNS: Radio Network Systems

• RNC: Radio Network Controller

• Node B: a UMTS term to denote

the BTS

• Interfaces:

– Node B x RNC : Iub

– RNC x RNC : Iur

– RNC x CN : Iu

• A UE can be served by multiple

cells simultaneously

• Node B uses WCDMA

Performing a target test at NodeB (cont)

Components in Environment

NodeB is real hardware with radio communication equipment,

amplifiers, alarms, a T1/E1, optional T3/E3, and OC3/STM1 facilities

interface, Ethernet switch, filters, and a user alarm interface

RNC : simulated

UE : real/ simulated (Qualcom , Ubinetics )

PET : Perl language

RMT : tool

Radio

Converter box

Linux box.

GUI tool for testing

- NPT – Nash Protocol Tester

NPT® is the Perl Environment for

Testing

Nash Protocol Tester is a

simulator for telecommunication

systems

interactive testing is supported

by NPT® using Perl

script language allows you to

implement almost any test case

Image source: from internet

Perl Environment Test

simulating the RNC/Core Network part of the Iub

interface

Allows complete simulation of various protocol stacks in

UMTS

Can control a lot of other test equipment, like VSA,

signal generators, test mobiles

Provides interface to test management system, e.g. for

submission of test results of automatic tests

Operational System

Pet Log Viewer

Verify scope of testing

Ensures that a SW release is basically running straight

forward at the NodeB.

Verifies the functionality of the NodeB network element at

its defined interfaces within a simulated environment.

Cover new features of the NE as well as features included

in previous releases.

Verifies impact on an already stable system

Check software fulfilling the given system requirements at

a specified hardware configuration
