LTE EPC Tester
Telecom
Long Term Evolution (LTE) is the next-generation, high-speed wireless broadband technology. Evolved
Packet Core (EPC) is at the heart of a LTE network and is required to process massive amounts of data. It
handles User Data sessions with varied Quality of Service (QoS) and processes millions of control
transactions per second. Hence the EPC (MME, SGW and PGW) needs to be thoroughly validated
throughout the Product Life Cycle in order to meet the operator expectations.
At Tata Consultancy Services (TCS), our LTE EPC Tester addresses these needs to effectively validate the
EPC from a functionality, performance, capacity and robustness viewpoint.
Overview
The ability to test the EPC with field like situations under traffic is
imperative to EPC product quality. Towards this, Equipment Vendors
(EV’s) seek Simulators that can test near to field scenarios. EV’s also
want their Test Tools to evolve in-line with the changing 3GPP
standards without making significant time & effort investments.
TCS’ LTE EPC Tester addresses the above needs. It simulates UEs and
eNBs to effectively test the EPC for Control, User & Management
planes. It is a software-centric solution designed to test in a multiuser, multi-eNB configuration. The solution is low cost, scalable and
runs on Linux platform. It is customizable and can be backward
integrated to legacy test assets.
It can be used by the Design, Product Verification & Validation
organizations of an EV.
