27-212 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Monitoring the Mobility Management Entity 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 signaling load in the network, you can group multiple MMEs in a pool to meet this load. It is 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. Remove DNSRight-click the context > Commands> Configuration> Others> Remove DNSUse this command to remove a DNS.

27-213 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Monitoring the Mobility Management Entity Figure 27-22 depicts the topology of the LTE network along with MME: Figure 27-22 MME Topology The different features of the MME are listed below: Involved in bearer activation/deactivation Provides P-GW selection to the subscriber to connect to PDN Tracks the UE for idle mode and paging procedures, including transmissions Chooses the S-GW for a UE during initial attach and also at the time of intra-LTE handover involving Core Network node relocation Authenticates the user (by interacting with the HSS) Works as a termination point for Non-Access Stratum (NAS) signaling Generates and allocates temporary identities to the UEs Checks whether the UE is authorized to camp on the service provider’s Public Land Mobile Network (PLMN) Enforces UE roaming restrictions Handles security key management Communicates with other MMEs in the same or different PLMN There are many different MME interfaces, which are listed below:
27-214 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 Chapter 27 Managing Mobile Networks Monitoring the Mobility Management Entity S1-MME Interface—The interface used by MME to communicate with eNodeBs on the same PLMN. This interface is the reference point for the control plane protocol between eNodeB and MME, this interface uses the S1 Application Protocol (SI-AP) instead of the Stream Control Transmission Protocol (SCTP) as the transport layer protocol for guaranteed delivery of signaling messages between MME and eNodeB. It serves as a path for establishing and maintaining subscriber UE contexts and supports IPv4, IPv6, IPSec, and multi-homing. S3 Interface—The interface used by MME to communicate with S4-SGSNs on the same PLMN for interworking between GPRS/UMTS and LTE network technologies. This interface serves as a signaling path for establishing and maintaining subscriber UE contexts. The MME communicates with SGSNs on the PLMN using the GPRS Tunneling Protocol (GTP). The signaling or control aspect of this protocol is referred to as the GTP Control Plane (GTPC) while the encapsulated user data traffic is referred to as the GTP User Plane (GTPU). One or more S3 interfaces can be configured per system context. S6a Interface—The interface used by MME to communicate with Home Subscriber Server (HSS) on PLMN using the diameter protocol. This interface is responsible for transfer of subscription and authenticating or authorizing user access and UE context. S10 Interface—The interface used by the MME to communicate with another MME on the same or a different PLMN using the GTPv2 protocol. This interface is also used for MME relocation and MME-to-MME information transfer or handoff. S11 Interface—The interface used by the MME to communicate with Serving Gateways (S-GW) for transfer of information, using the GTPv2 protocol. S13 Interface—The interface used by the MME to communicate with the Equipment Identity Register (EIR). SGs Interface—The interface used to connect the databases in the VLR and MME to support circuit switch fallback scenarios. Sv Interface—The interface used by the MME to connect to the Mobile Switching Center to support exchange of messages during a handover procedure for the Single Radio Voice Call Continuity (SRVCC) feature. Gn Interface—The interface used to facilitate user mobility between 2G and 3G 3GPP networks. This interface is used for intra-PLMN handovers. SLg Interface—The interface used by MME to communicate with the Gateway Mobile Location Center (GMLC) using the diameter protocol. This interface is used for the Location Services (LCS), which enables the system to determine and report location information of the connected UEs. Viewing the MME Configuration Details To view the MME configuration details: Step 1Right-click the required device in the Vision client and choose Inventory. Step 2In the Logical Inventory window, choose Logical Inventory > Context> Mobile > MME. The list of MME services configured in Prime Network is displayed in the content pane. Step 3From the MME node, choose an MME service. The MME service details are displayed in the content pane as shown in Figure 27-23.
