LTE Standards and Architecture
Jean‐Gabriel Rémy, Charlotte Letamendia · 2014
The 3rd generation partnership project (3GPP) is presented as a collaboration working group between different standard bodies specialized in telecommunication. 3GPP also include test specifications, which describe how to verify the compliance of the industrial realization. Specifications are then put into releases that present each a set of features and specifications, which is internally consistent. Each release is composed of hundreds of individual standard documents. Each document may have supported many revisions. Current 3GPP standards include the latest version of Global System for Mobile communication (GSM), Universal Mobile Telecommunications System (UMTS) and Long-Term Evolution (LTE) standards. The evolved architecture comprises evolved universal terrestrial radio access network (E-UTRAN) on the access side and evolved packet core (EPC) on the core side. Subscriber's identity module (SIM) is an important network element in the GSM system.
