3GPP, what is it ?
3GPP is responsible for developing the "3GPP technical specifications".
Those technical specifications are considered the global standard for different mobile network technologies, including GSM, UMTS, LTE, and 5G.
3GPP is a partnership of several organisations, including network operators, equipment vendors, software developers, and research organisations. These organisations work together to develop and maintain mobile network technical specifications.
3GPP Releases
3GPP organises its technical specifications into major releases, with each release introducing new features and capabilities.
Here's an overview of the major releases,
- Release 99 (year 2000): The first release of the 3G UMTS standard, enabling services like video calling and mobile internet.
- Release 4 (year 2001): Introduced IP Multimedia Subsystem (IMS) architecture for delivering multimedia services over IP networks.
- Release 8 (year 2008): Marked the transition to 4G, and introduced Evolved Packet Core (EPC) architecture.
- Release 15 (year 2018): Specified the 5G New Radio (NR) air interface and 5G Core network (5GC).

5G Core Network Architecture
In this post, we will learn 5G Network Architecture. The control plane in 5G network includes the AMF, the SMF, the AUSF, the UDM, and the PCF. While the user plane includes the UPF. The control plane is not including those network functions only, there are another network functions in the control plane, that will be discussed later. In…

LTE (4G) Network Architecture
LTE (4G) Network Nodes LTE refers to 'Long Term Evolution', and the architecture of the LTE (4G) network is as following, eNodeB The eNodeB is the 4G site that the UE connects to. It provides the radio interface to the UE. MME MME refers to 'Mobility Management Entity'. The MME is responsible for authenticating the…

SGSN, GGSN – 2G/3G Network Architecture and Interfaces
2G/3G Network Nodes The following graph shows the 2G/3G Network Architecture. It includes the SGSN, GGSN, HLR, CG, PDN, RNC, and BSC. SGSN GGSN, HLR, CG, PDN, RNC, BSC, 2G/3G Network Interfaces Now we know the nodes that exist in the 2G/3G network. Let's learn the interface names that exist between those nodes. Every interface…
