UMTS Iu Signaling Tester

Test Harness & Test Suite for the Validation of UMTS Iu Implementations.

UMTS Iu Conformance Test Architecture

Overview

The UMTS Iu Signaling Tester is a test environment for the UMTS Iu Radio Interface Layer 3, RANAP & ALCAP signaling specification as defined by the ETSI standards.  It is a SAFIRE based test harness able to run pre-defined ACATS test scenarios against UMTS Iu test objects in a controlled & deterministic manner.

The SAFIRE graphical editor allows new scenarios to be created or existing scenarios to be modified using the Iu Radio Interface Layer 3, RANAP & ALCAP interface library (APIs), which defines the UMTS Iu messages and parameters. The test harness includes a UMTS Iu protocol analyzer for on-line capture and decode of the signaling in real-time both during tests and as a stand-alone tracer for live systems.

The UMTS Iu Signaling Tester is suitable for conformance tests, functional tests, factory tests & acceptance tests.

Key Features

• Fully integrated, complete test environment for UMTS Iu
• ISO conformant test scenarios giving framework coverage of UMTS Iu
• Graphical development environment & libraries for creating new UMTS Iu tests
• Compatible with ACATS UMTS Iu Professional Test Suite (not included)
• Expandable for ATM over E1/T1 & UMTS Iur Interface
• UMTS Iu Reference Test Object

Network Architecture

Description

The UMTS Iu Signaling Tester was designed to be a complete solution for UMTS Iu Radio Interface Layer 3, RANAP & ALCAP signaling test requirements.  It has the key components:

• UMTS Iu Test Harness including codec & SS7 or SIGTRAN stack
• ACATS UMTS Iu Framework Test Suite
• UMTS Iu Radio Interface Layer 3, RANAP & ALCAP Interface Library
• UMTS Iu Radio Interface Layer 3, RANAP & ALCAP Protocol Analyzer

The UMTS Iu test harness uses the powerful SAFIRE environment to provide advanced features like

• Graphical editing (flow diagram representation)
• Automated execution of test campaigns
• Slow motion replay with synchronized trace & breakpoints
• Test reports with statistics (also HTML)
• Real-time, high performance protocol analysis

Using the UMTS Iu Signaling Tester, test objects can be accurately, reliably and comfortably validated for compliance with the ETSI TS 25.413, 25.414 & 04.08.  It is suitable for manufacturers, network operators and service providers to address all stages of the development cycle, regression testing through to type approval, acceptance testing & certification (note:  requirements may be country/organization specific).

The ACATS UMTS Iu Framework Test Suite includes test scenarios for the validation of UMTS Iu equipments by simulating the controlled interaction with other UMTS Iu entities such as

• MSCu
• 3G SGSN
• RNC

SAFIRE Editor Sample

The framework test suite contains a selection of important scenarios, which can be used to confirm the basic functionality of a UMTS Iu test object for Radio Network & Transport Network Control Plane procedures.  They are also an excellent basis for customization and enhancement according to specific needs.

An upgrade is available for the ACATS UMTS Iu Professional Test Suite, which offers extensive coverage of the UMTS Iu signaling test requirements.

UMTS Iu Reference Test Object

For reference a virtual test harness is included, that allows test scenarios to be run off-line against a software-only test object under controlled conditions.  The test harness uses a software bus to replace the physical connection and an accurate software model as the test object.  Normally fully automated execution of tests is possible, but in some specific cases the test object allows/requires user interaction during the tests.
