Master thesis project

This page is about my Master thesis project. The content will be updated continually during the project and you will be able to find all related information such as deliverables, weekly reports and time plan to the project.

· Introduction

The objective of the project is to perform a technical but also a strategical futurological study about terminals (PDA and cellular phone) role in a multi access environment. A multi access environment is the access from a terminal through an access point (e.g. GPRS, WLAN and bluetooth) to the net (as Internet, intranet, telephone network or mobile network), where the terminal can chose between two or more access points. The assumption is a network having many different (wireless) accesses and that the user should be able to move between accesses, either keeping the session or doing the movement between sessions. The future prospective is 2-5 years.

The access points, which are expected to be in use in this approach, are wireless bearer such as GPRS, UMTS, WLAN (incl. H/2), Bluetooth etc.

Some questions of interest to be answered are:

- How to select an access method in a multi access environment? The access points, which will be examined, are UMTS, GPRS, GSM, WLAN and Bluetooth.

- Where should the logic for the access option be placed? In terminals, net or applications?

- What are the requirements of the terminal considering where the logic is placed?

- How does the Bluetooth as a link to WLAN/PGRS/UMTS works?

The questions will be illustrated from a technical point of view and they will support Telia’s business.

· Method

The Master thesis project will begin with a pre-study period where the limitation will be made and the issue and area for deeper study will be defined.

Therefore follows a deep study that is the major part of the thesis. Contacts with other person and project are important to the input for the project.

A multi access environment can be illustrated from the following picture that includes a several communication paths.

NET

GSM

GPRS

Examine the path (red):

1. PDA -> UMTS

2. PDA -> PGRS

3. PDA -> BT -> MOBLIE -> UMTS

4.

UMTS

PDA -> BT -> MOBILE -> PGRS

6. PDA -> BT -> WLAN

Already exists / will exist (black)

1.

Mobile

PDA -> WLAN/BT -> NET

2. MOBILE -> GSM/PGRS/UMTS -> NET

Process outline

1. Find the persons/project/exjobb dealing with the area.

2. Study every communication path and the handover their between.

3. Which ones of the communication paths will exist in 2-5 years?

4. Making a roadmap about the com. paths.

5.

PDA

Apply the questions above on every com. path.

(The questions are under the introduction above)

6. Investigate the integration of the com. paths.

7. Apply the questions above on the integrated com. path.

· Goal and result

This study should answer (some of) the above questions, identify new relevant question at issue and try to find technical and strategical solutions appropriate for Telia as an operator.
