What is 3GPP

3. 1. 3GPP Specification Are Interlinked
Each specification in 3GPP has many referenced specifications
2. 3GPP Specifications Do Not Cover Examples
As many part of 3GPP specification are left implementation dependent, they do not cover
many examples.

Specifications like RRC (Radio Resource Control, 25.331) are huge in size. Some of them contain more
than 1000 pages.
4. So Many Technologies
3GPP specifications cover UMTS, GSM/GPRS/EDGE, HSPA, IMS, LTE and many other
technologies
Problem

5. 1. Know What You Want To Read
For example if you want to know detail about cell reselection, you should start with idle
mode specification 25.304.
2. Study The Respective Specification First Then Go To The

It is always get confused easily if you start following the references before reading the

It is good for the environment not to take printouts, but it is always helpful to make printout of the part
you are just studying.
4. Follow What You Are Studying
When you start reading a specification try to follow the whole. This way the fundamental of
the protocol layer or technology can be understood easily.

7. 5. Examples Can Solve Your Problem
This is always true that examples can help you a lot to understand certain parts of specification.
