MME in 4G-LTE Telecom Network
MME stands for "Mobility Management Entity". It is a key component of the 4G Evolved Packet Core (EPC) network.
The MME handles the initial attach of the user equipment (UE) to the network. It Authenticates the user and authorises their access to the network. In addition, it handles the mobility management of the UE, and tracks the UE location.
Also it selects the appropriate gateways (S-GW and P-GW) for the user's data session.
The MME communicates with various network elements, such as the eNodeB, Home Subscriber Server (HSS), Serving Gateway (S-GW), and Packet Data Network Gateway (P-GW), to perform its functions.
