2010.08 - Next Generation Service and System Management (NGSSM)
2011.12
Ericsson - Backnang, Germany

Description: A Next Generation Operational Support System (NGOSS) is platform architecture for
the management of Next Generation Networks (NGN). It provides seamless
integration of Operational Support Systems (OSS) by providing a single interface for
the customer systems interaction. It provides services for Fulfillment, Operational
Support and Readiness (OS&R) and Mediation.
The Element Abstraction Layer provides seamless access to the Operational
Support System to perform Provisioning, Discovery, Backup and Restore operations
on IMS Platform through a standard Multi-Technology Operational Support Interface
(MTOSI) interface agreed between the vendors.

Each IMS network element can be accessed via some specific protocol e.g LDAP,
NETCONF, SSH, SNMP etc. To keep the transparent communication between the
vendor's applications, the MTOSI requests are standardized and agreed between the
vendors for different Network Elements of IMS system.

The EAL gets the MTOSI requests on its north bound interface; a specific adapter
translates the MTOSI request into the format supported by the specific network
element and sends the formatted request to the network element connected to its
south bound interface. The response from the network element is translated back to
the corresponding MTOSI format and sent back to the client via north bound
interface of EAL.


Roles: - Subject matter expert for technical issues, and Interface Agreement of
Fulfillment and OS&R areas of OSS.




- Development lead Fulfillment modules (HSS, SLF and MTAS) .
- Testing and trouble shooting of entire OSS Element Abstraction Layer and its
north and south bounds.


Tasks: - Planning and preparation of Interface Agreement for fulfillment part of OSS
between the vendors.
- Development and enhancement of the fulfillment related adapters.
- Installation, deployment and trouble shooting in the customer premises.
- Dealing with customer queries and troubleshooting regarding fulfillment and
OS&R issues in Live and Test Networks.
- Preparation of test environment, test-plan and test documents for fulfillment and
OS&R adapters.
- Testing of the functionality of all fulfillment and OS&R related adapters for under
the light of Interface agreement.
- Trouble shooting and error analysis.
- Comparison of network elements behavior with the request sent by the adapters
and manually sending the direct request by using the corresponding protocol.

Vodafone - Eschborn, Germany


Description: The Automatic Testing Framework provides a test platform for telecommunication
networks, which supports tests on a functional level. The aim of this system is to
automate system tests with very high test coverage, which are capable of mitigating
the combinatorial explosion. The tone test sub-system is an ATF module responsible
for automated verification of speech quality.

The Tonetest is in charge of playback and recording of audio data on the given audio
channel. The recorded WAV file is compared with the original WAV file by using
Perceptual Evaluation of Speech Quality (PESQ-Algorithm) and the calculated speech
quality of the recorded wave file is reported to the upper layer of the ATF system.

Role: Development and Testing

Tasks: Development of the application for recording and playback of audio data, as well as
volume control on the given audio channel. The raw audio data can be recorded in any
of the given WAV formats (sample-rate, bit-rate, mono/stereo). Furthermore this
application also provides the volume control on the corresponding audio channel for
playback and recording of WAV data.

NOKIA - Berlin, Germany

Description: The Reports Center provides an interface to collect test results from automated and
manual tests. The manual test results are collected by a Data Collector Agent (ruby




script), which collects the data from different client machines, parses the data and
sends the data to the Web Service of Report Center.

The results of Automated test are sent directly by the Test Automation System to the
Report Center through the same interface. Test-Reports for each System Under Test
are provided in a numerical and a graphical format which helps the top management
see the status of the product and it helps testers to compare the errors, error rate and
error description with previous releases as well as with different browsers for the error
reporting.

Furthermore a Database-Backup agent was developed to maintain the backups on
daily, weekly, monthly and yearly basis. A proxy server was developed to perform a
"Man in the middle attack". This proxy interrupts the communication between the client
and the server, it manipulates the response from the server and sends it to the client, in
order to check the behavior of the Plug-in.

Role Development and System Administration

Tasks: - Development of a Report Center to collect manual and automated Testing results
- Development of a Data Collector Agent
- Development of a Database Backup Agent
- Development of a Proxy Server
- Administration of Database, Web and Application Servers

2008.09 - 2009.02 ATF - VoIP Generic Human Interface Adaptation

Vodafone - Eschborn, Germany




Description: Generic Human Adaptation is developed as an extension to Automated Testing
Framework. GHIA provides a new way of integration with the terminal equipment that
does not provide a communication interface from where a test automation can take
place, e.g. terminal equipment which does not provide a COM or USB port.

GHIA enables ATF to communicate with the terminal equipment by using its standard
user interface, for example a key board for a telephone. The realization of this project
involved the creation of the platform and the integration of the keyboard and the
protocol analyzer interface (SIP) using Snom IP phones as terminal equipment.

Role Development and Testing

Tasks: - Development of the SIP protocol tracers, to update the state machine of ATF-
GHIA
- Writing of testcases and Test specifications for GHIA
- Preparation of test environment for GHIA
- Installation of ATF and GHIA components
- Configuration and intercomponent communication
- Blackbox and Whitebox testing of GHIA

Framework in order to provide the test automation facility for SIP based client.
ATF targets to automate functional regression tests for Mobile, ISDN, Analog and VoIP
Network infrastructure configurations. It provides a powerful platform to perform end-toend
system verification.

The TeSip client is an application which works as a middleware between TeSip API
and TeSip Test execution driver called TED. The TeSip client receives control
instructions from TeSip TED in the form of AT commands and calls relevant function
from TeSip API to execute received AT commands and sends back the results
received from TeSip API to the TED in the form of AT commands via a TCP socket
connection.
