27-221 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Monitoring the Mobility Management Entity You can also view the following configurations for a MME service: EMM Timeouts—EPS Mobility Management (EMM) is used to support the mobility of a user equipment. For example, it informs the network of the UEs current location and provides user identity confidentiality. Apart from these services, it also provides connection management services to the session management sublayer and defines timer parameters such as timeout durations for retransmission of NAS messages. ESM Timeouts—EPS Session Management (ESM) is used to provide subscriber session management for bearer context activation, deactivation, modification and update procedures. LTE Security Procedures—The LTE integrity and encryption algorithms used for security procedures for the MME service, which are enabled by default. Policy—The session management policies for LTE subscribers of the MME service. S1 Interface—Transfer of signaling messages between the MME service and the eNodeB. S1 MME uses the S1 Application Protocol (S1-AP) over the Steam Control Transmission Protocol (SCTP).
