Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.

Abstract (eng): The topic of this thesis is design, development and successful testing of application layer of user plane server of Voice over IP (VoIP) prototype, featuring Push-to-Talk over Cellular (PoC) services like instant individual and group calls between users.

The prototype is a basic VoIP system implemented using separate control plane server, and user plane server.
The control plane is responsible for handling signalling based on SIP (Session Initiation Protocol) protocol, while user plane handles low level processing based on RTP protocol.
The communication between control plane and user plane is via MEGACO (Media Gateway Control Protocol) protocol.

The thesis work consisted of actual implementation of logic necessary to enable setup, process individual calls, group calls, check user rights to be able to use system, and group attachment related processing.
All software processing is implemented in C, C++ over Linux environment.

The system was implemented, tested and successfully demonstrated.

The result of this work show that it is possible to extend the system concept for further large scale development
