interface emulator

An LTE X2 interface emulator has been released by GL Communications. The emulator is designed to test and verify eNodeB implementations through its Message Automation & Protocol Simulation (MAPS) platform. The MAPS platform is a protocol simulation and conformance test tool that can emulate a variety of protocols over IP, TDM, and wireless networks.

LTE consists of a packet core and a network of eNodeBs. An eNodeB has two interfaces: the X2 interface permits eNodeBs to talk to each other directly, while the S1 interface permits talking to the packet core. GL's MAPS X2-AP interface emulator is used to coordinate handovers and perform load management between two eNodeB elements in an LTE network.

The X2-AP test tool offers utilities like a message editor, script editor, and profile editor to allow new scenarios to be created or existing scenarios to be modified using messages and parameters. It can be used to simulate up to 500 smart phones powering up and down, authenticate and confirm security procedures, and insert impairments to create invalid messages.

Further information regarding the MAPS platform can be found here.
