Mobility Management Entity(MME)

Mobility Management Entity(MME) is a key component of the standards-defined Evolved Pack Core (EPC) for LTE. It provides mobility session management for the LTE network and supports subscriber authentication, roaming and handovers to other networks.
Mobility Management Entity(MME)
Performance
Up to 500 eNodeBs per  instance
From 500 to 10M subscribers 
Support redundancy deployment
NFV Deployment on COTS and Cloud

IPLOOK's Virtualized MME
Fully standards-compliant MME in service in many operator networks around the globe
The IPLOOK's vMME is a fully standards-compliant core network product and has been integrated with the hardware and software of all telecom suppliers. It is the control plane node of EPC and deals with the signaling plane and completes the authentication with HSS.
Our Carrier Grade MME adopts COTS server as the platform. The MME function can be NFV element and deployed in the data center environment. The MME application can also be directly deployed in a server to make full use of the hardware capability.

Evolved Packet Core(EPC)
With the development of network technology, smartphones, laptop computers have been widespread. Unlike traditional wired phones, mobile smartphones allow users to easily access the Internet, download or upload files, and use different applications.

Long Term Evolution/Evolved Packet Core (LTE/EPC) is an innovation which depends on GSM/EDGE and UMTS/HSPA technologies, can increase the capacity and speed using a different radio interface together with core network improvements. EPC refers to a core network architecture that aggregates access networks including LTE, 3G or 2G.

HSS/HLR
A Home Subscriber Server(HSS) / Home Subsriber Register(HLR) serves as the primary database repository of subscriber information within a LTE/EPC or IMS network core. By centralising all the subscriber information in a single place it allows the signalling to be separated from policy providing a stream lined, high performing network.

SGW(Serving Gateway)
The SGW node handles the user data traffic, but isn' t responsible for the signaling data used. It transports IP data from UE's to the LTE Core Network. The SGW also routes incoming and outgoing IP packets for better system collaboration and serves as an anchor for the UE when it moves from one eNodeB to another.

PGW (PDN Gateway)
PGW is the network node that connects the EPC to external IP networks. What the PGW does is that it routes packets to and from external IP networks. Beyond that, it also allocates an IP address to all UEs and enforces different policies regarding IP user traffic such as packet filtering.
