Monitoring the Mobility Management Entity
Mobility Management Entity (MME) is the key control-node for an LTE access network, which works
in conjunction with NodeB(eNodeB), Serving Gateway, or the LTE/SAW core network. It is responsible
for initiating paging and authentication of mobile devices. It keeps location information at the Tracking
Area Level for each user and chooses the right gateway during the initial registration process.
The MME uses the SSI-MME interface to connect to an eNode and uses the S11interface to connect to
a S-GW. In case there is an increase in the signalling load in the network, you can group multiple MMEs
in a pool to meet this load. It ia also the termination point in the network for ciphering/integrity
protection for NAS signaling.
MME supports lawful interception of signaling and provides the control plane function for mobility
between LTE and 2G/3G access networks with the S3 interface terminating at the MME from the SGSN.
It also terminates the S6a interface towards the home HSS for roaming UEs.
