> And same here – I've read a few of the 3GPP specs, but they make legalese sound like plain English, and of course never tell the full story including actual manufacturer decisions.
They are technical standards designed to ensure interoperability (though not always successfully — cough VoLTE cough) rather than exhaustive guides on how to implement features. They have been developed over a long period of time and have become quite complicated to read, especially if you are not familiar with the specific nomenclature. However, with enough time and willpower you can make sense of them quite quickly.
PS. The software behind these standards is probably the most complex we have in the world. At least I am not aware of anything else that is as complicated.
