How to begin?

In order to begin... I got to understand the title of the thesis. Obvious, but got to express it! So, I got to have an understanding of some key concepts:

• Network Slicing
• 5G
• Security

These concepts seem very broad, but by exploring the literature during the State of the Art (SOTA) review, I think I can narrow down the meaning of all of this under the scope of mobile networks. According to my experience and precious reading, I think I would have to revisit concepts from NFV and SDN, as cornerstone for and automatized network.

And well, where to search for information about those concepts? My advisers recommended me to check the main standard development organization (SDO) documents that talk about the subject. Since all of this is under construction, I am sure I will have fun reading all these documentation.

I will focus on 3 SDOs:

• 3GPP
• ETSI
• 5GMN

There is other from 5G Americas, but it will be a bonus "just in case".

As the reading and analysis advances, I will be posting a summary and my point of view on the key concepts.

New challenge! Ph.D.

Well, it is time to revisit my blog and start writing again. I think this will be a good exercise, because it will help to relieve from stress, have a way to "talk to myself" and express ideas about the current challenge I am facing. 

As I read somewhere: "if you can't explain it, you don't understand it". So this will be a way to test myself if I am improving the understanding of the topics.

The new challenge refers to my doctoral study about securization of network slices for 5G. The topic is brand-new, with a lot of subtopics to consider. There can be several approaches depending on the background expertise: the radio access network (RAN), the core network (user plane? control plane?) access to services and applications... I think my focus would be in the core network regarding the way in which the network slices are created and the life-cycle management. 

The idea is to begin exploring and start to get a better understanding of the concepts and try to build a road-map in order to not get lost in this quest.
