In the preceding sections, we have discussed mobile communications network architectures along with their various network elements which are based on the GSM, UMTS, LTE, and 5G technologies. The interconnected network elements, either from the same or different OEM(s), provide end‐to‐end mobile communications and broadband services to subscribers. A network element communicates with another network element(s) through a standard protocol like the different PCs, and servers use Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols to communicate with each other over the Internet. There are international bodies that define and standardize various standard protocols such as TCP/IP, File Transfer Protocol (FTP), and Internet Control Message Protocol (ICMP). Similarly, the protocols and architectures used in a mobile communications network with interconnected network elements are defined and standardized by an organization called 3rd Generation Partnership Project, shortly called as 3GPP. It is a collaborative effort among different organizational partners. Those partners are ARIB, ATIS, CCSA, ETSI, TTA, TTC, and TSDSI, which are regional and national standards bodies, from Asia, Europe, and North America. See Figure 2.15.

The 3GPP and its organizational partners develop and standardize the architectures and protocols used in a mobile communications network. In a nutshell, start visiting the 3GPP site [1] right away to learn more about the 3GPP and its structures and crawl through the various information available under the different pages. The 3GPP site contains all the required information which is a key to know about the standardization processes of mobile communications systems and networks and their network elements that span across its different system engineering areas. A mobile communications network, consisting of the system engineering areas shown in Figure 2.14, that is conforming to 3GPP specifications is said to be a 3GPP compliant communications system.
