LTE eNodeB Emulator

4

implementation designed

for lab use and for testing

MME, S-GW and PDN-GW.

It implements all the 4

required protocols-

S1AP/SCTP to

communicate with MMEs

over S1-MME interface

and GTP-u to

communicate with S-GW

over S1-U interface.

An eNodeB The LTE eNodeB Emulator is a part of the family of LTE Network Equipment Emulators from Polaris Networks. The LTE

Network Equipment Emulators together allow testing in a variety of network topologies, allowing the user to utilize lab

equipment effectively and reduce capital expenditure and ongoing support costs associated with a test lab. The eNodeB

Emulator provides a lower-cost solution and greater control as compared to a real eNodeB for testing the functionality,

scalability and performance of LTE Network Equipment, including MME, S-GW and P-GW.

The eNodeB Emulator includes all the network interfaces and implements all the communication protocols required for

an eNodeB to operate in an LTE/SAE network. In addition, the eNodeB Emulator provides a scripting interface (using the

TCL programming language) to configure and control its functions and obtain performance statistics and test results. The

eNodeB Emulator also supports the ability to emulate multiple eNodeBs for the purpose of scalability testing.

FEATURES

è LTE Network Equipment Manufacturers can use the Emulator both for Unit Testing during product

development and for System QA and Regression Testing. The Emulators can test the functionality and scalability

and measure the performance of various network elements, by simulating procedures such as UE Attach, Detach,

Dedicated Bearer creation and end-to-end Data Transfer.

eNodeB

è LTE Network Operators can use the Emulator in a pre-deployment test bed to validate the Key

Performance Indicators provided by equipment vendors, such as busy hour call attempts and the number of

simultaneous active bearers.

eNodeB

è The Emulator can be used to simulate failure scenarios during Session Setup, Subscriber

Authentication and Bearer Setup and to simulate error scenarios such as incomplete signaling.

eNodeB

The eNodeB Emulator includes

è The S1AP and SCTP protocols required to communicate with an MME. It can communicate with multiple MMEs

and it can emulate multiple eNodeBs at the same time for testing Handover scenarios.

è The X2AP and SCTP protocols required to communicate with an eNodeB.

è The GTP-u protocol required to communicate with a S-GW.

è A scripting interface using the TCL programming language to configure and control its functions and obtain

performance statistics and test results. This automation of control allows the user to run many test cases

simultaneously or serially and to create real-world scenarios for heavy load and long-duration stability tests.

è A Graphical User Interface (GUI) that can be run on any Windows or Linux computer. The GUI allows the user to

manage a cluster of Polaris Networks LTE Network Device Emulators from a single console. It provides an easy-to-

use method to configure and control the functions of the Emulators and to display device and connection status and

performance statistics.

è A UE Simulator so that the eNodeB Emulator can be used to test an MME, eNodeB or S-GW without requiring a

real UE. The UE Simulator can be used to simulate UE Attach, Detach and Handover scenarios and generate User

Traffic towards the S-GW

ð eNodeB Emulator runs on a PC with x86 or x86-64 CPU, Linux OS and minimum 2GB RAM.
