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):In the contemporary legacy mobile wireless networks, the Network Elements and their associated parameters are manually configured.
The manual intervention method to configure and optimize the network parameters in the current mobile networks exhibiting Heterogeneous Networks (HetNet) scenario is almost unmanageable for network operators.
Self-Organizing Network concept was introduced by 3GPP for the Long Term Evolution (LTE) systems to achieve a high degree of automation in the planning, configuring and optimizing network parameters.
Physical Cell Identity (PCI) and Neighbor Cell List (NCL) are two key radio configuration parameters that are configured during Dynamic Radio Configuration phase of the self-configuration.
This Thesis makes a survey on the standardized PCI and NCL configuration in LTE systems and addresses the challenges in configuring these two radio parameters in HetNet scenarios.
The objective of this Thesis is to perform a survey on the prospect of Automatic Neighbor Relation management in dynamic HetNet scenarios.
The new capacity and coverage boosting enhancements that are introduced in 3GPP Rel-11 and on-wards, in particular, energy saving solutions and Active Antenna Systems (AAS) techniques are most probable to create a dynamic network scenarios.
This Thesis identifies the potential solutions for energy saving and AAS techniques, and performs the initial impact analysis on the network stability and neighbor relations.
