MME Insights | Sumble

What is MME?

MME stands for Mobility Management Entity. It is a key control-node in a 4G LTE (Long-Term Evolution) network. It is responsible for tasks such as tracking and paging mobile devices (UEs), managing security, handling authentication and authorization, and managing mobility (handover) between different base stations (eNodeBs). Essentially, it manages the connection between the mobile device and the core network.

What other technologies are related to MME?

MME Competitor Technologies

SGSN

The SGSN (Serving GPRS Support Node) provides packet routing to/from the UE within its service area, for 2G and 3G networks. It's functionally similar to the MME, but for older generation networks. Thus, it's a competitor in that older technologies are replaced by LTE/EPC.
