Some of the benefits found in deploying the system include.
Table 1. Features and Benefits of the System
Feature Benefit
Mobility Management Entity
(MME) service support in
LTE/SAE networks Delivers unrivaled throughput, call transaction rates, and packet processing, along with
significant memory resources.Provides UE state management (attach, detach, idle, RAN
mobility), authentication, paging, mobility with 3GPP 2G/3G nodes (SGSN), roaming, and
other bearer management functions. Also provides Integration of multiple core network
functions.High transaction rates for attaches, activations, TAUs, handoffs, and paging along
with congestion management, load sharing, and MME pooling.MME provides intelligent
signaling heuristics to maximize performance and self Optimizing Network (SON)
capabilities to the radio and packet core network. It also provides dynamic optimization of
network topology based on usage patterns to reduce latency and backhaul costs.Circuit
Switch (CS) Fallback for voice traffic
Mobile data service support for
WiMAX networks Provides WiMAX ASN GW, WiMAX Foreign Agent (FA), and WiMAX Home Agent (HA)
services within a single chassis, or as distributed network functions supporting both Simple
and Mobile IP.Provides WiMAX ASN Paging Controller and Location Registry (ASN
PC/LR) services within a single chassis, or co-located as distributed network functions
supporting paging procedures for idle mode entry and exit and location update.Provides
multiple host support behind a WiMAX Customer Premise Equipment (CPE) through one
primary airlink sessionProvides optional base station monitoring feature to monitor base
stations attached to it.
Wireless data service support for
3G CDMA2000 and
GPRS/UMTS and for 2.5G/3G
GPRS/UTMS networks
Provides Packet Data Service Node (PDSN), Foreign Agent (FA), and Home Agent
(HA) services within a single chassis, or as distributed network functions supporting
both Simple and Mobile IP.
Provides Gateway GPRS Support Node (GGSN), Foreign Agent (FA), and Home
Agent (HA) services within a single chassis, or as distributed network functions
supporting basic data and Mobile IP functionality.
Provides Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node
(GGSN) services within a single chassis, or as distributed network functions
supporting both the control and data planes.
Wireless data service support for
Femto (UMTS/CDMA)
subscriber in 3G UTMS networks
Provides Home-NodeB Gateway (HNB-GW) service for Femto access network user
to connect voice and IP data traffic with CS/PS core network.
It supports multiple services on a single chassis or as distributed network functions
supporting enhanced voice and IP data functionality.
Proxy Mobile IP Provides a mobility solution for subscriber‘s with Mobile Nodes (MNs) that do not
implement the Mobile IP protocol stack.
Full Handover Support Compliance with 3GPP procedures for Mobility Management, Location Management, and
Session Management ensure high volume, load-balancing, and successful handover.
