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.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): The evolution of telecommunication networks has led to a situation where the usage of traditional fixed telecom services has been replaced with wireless and IP-based solutions.
Network operators have identified this trend and have started to migrate their networks towards IP based Next Generation Network.

Network migration is a complicated process and requires a lot of different analyses.
Migration needs to be optimized so that the maximum revenue is obtained during a transition process while at the same time customer satisfaction is maintained.
This thesis describes how analyses help to manage and predict migration process effectively.
Two separate analysis solutions are presented: A tool to predict the development of customer amounts and a tool that helps to obtain the most optimal migration order.

The overall benefits of these tools will become evident in the future when the migration has progressed further but the first obtained results are encouraging.
During the implementation of the analyses it was identified that a more evolved analysis platform is needed to replace Microsoft Excel currently in use.
Abstract (fin): Tietoliikenneverkkojen kehitys on johtanut tilanteeseen, jossa kiinteän verkon teleliikennepalvelujen käyttöä on korvattu langattomilla ja IP-pohjaisilla ratkaisuilla.
Verkko-operaattorit ovat tunnistaneet tämän kasvavan trendin ja ovat alkaneet muuttamaan verkkojaan IP-pohjaiseen seuraavan polven verkkoon.

Verkkomigraatio on monimutkainen prosessi ja se vaatii paljon analyysityötä tuekseen.
Migraatio täytyy optimoida niin, että saavutetaan maksimaalinen liikevaihto siirtymävaiheen aikana ja samalla ylläpidetään myös asiakastyytyväisyyttä.
Tämä työ tutkii miten analyysejä hyödynnetään migraation hallinnassa ja ennustamisessa.
Työssä esitellään kaksi eri esimerkkiä analyyseistä: Analyysiratkaisu, jolla kyetään ennustamaan liittymämäärien muutosta, sekä analyysi, jota hyödynnetään optimaalisen migraatiojärjestyksen määrittelyssä.

Näistä analyyseistä saatava kokonaishyöty selviää vasta, kun projekti on edennyt hieman pidemmälle, mutta alustavat tulokset ovat rohkaisevia.
Analyysejä implementoitaessa tunnistettiin tarve paremmalla analyysityökalulle tällä hetkellä käytössä olevan Microsoft Excelin tilalle.
