Study Notes

System Architecture Evolution (SAE) in 4G LTE networks

The main purpose of SAE is to provide a flat, all-IP architecture that enables multiple access technologies to be integrated into a single core network.

Interfacing with non-3GPP technologies

The entities managed to allow non-3GPP technologies to interface directly with the network in SAE are:
- Mobility Management Entity (MME)
- Serving Gateway (SGW)
- Packet Data Network Gateway (PDN GW)

X2 interface in evolved UTRAN

The purpose of the X2 interface is to facilitate communication between eNodeBs (eNBs) in the evolved UTRAN, enabling features such as load balancing, resource allocation, and handovers.

S1 interface in 4G LTE architecture

The S1 interface supports the separation of control and user plane traffic, allowing the MME to handle control functions and the SGW to handle user data.

Evolved UTRAN (E-UTRAN) in 4G LTE networks

The Evolved UTRAN consists of:
- eNodeBs (eNBs), which provide the radio access network functionality
- The X2 interface, which enables communication between eNBs
