DELIVER LTE SERVICES WITH CONFIDENCE

With LTE networks, maintaining a high level of performance is the key to maintaining the end-to-end stability of the system. The rapid proliferation of new smart devices on the market today and the resultant skyrocketing increase in signaling traffic, however, has made that task extremely difficult. In this new network operating environment, massive signaling storms often appear unexpectedly to cause delays, disrupt media flows, and negatively impact Diameter and SIP signaling performance.

Avoid Signaling Storms and Achieve Excellent QoE

The Spectra2 XL3 is your bulwark against signaling storms. A robust testing platform for validating both signaling and media performance, the XL3 covers the three most important dimensions of LTE network performance testing: Diameter transactions per second (TPS), Media/RTP simultaneous calls, and cumulative media quality of experience (QoE). With the comprehensive results generated from your testing you’ll be able to achieve the best possible performance from your network and deliver your services with confidence.

TYPICAL APPLICATIONS AND USE CASES

DSC/DRA/DRF/HSS/PCRF Load Testing

Carriers require extraordinary performance from Diameter routers as they interconnect the various nodes in the EPC and IMS—often as much as 300K-500K TPS per diameter routing agent (DRA) and 80K-300K TPS on HSS and PCRF nodes. The high-performing Spectra2, with its ability to simulate multiple interfaces, handles the extraordinary with ease. In many cases, a single XL3 system will fulfill most of your capacity testing requirements. Use cases also include the following:

• Multi-node simulation

• Mixed interface scenarios

• Multi-homing scenarios

• Traffic correlation testing

• Inter DRA connectivity

• DRA Relay/SLF routing

• Per port TPS engineering

• Avg. response time testing

• Open Transaction testing

• MME pool testing

• Base Conformance Testing

Media Load Testing

Voice over LTE (VoLTE), one of the primary LTE services commonly offered by operators around the world today, requires a connection to an IMS network for voice and video services. This creates additional requirements for testing media elements in the packet and IMS core, including the maximum number of simultaneous RTP calls, the AMR-WB codec used for voice communications, and the SIP and Diameter control signaling among multiple nodes in the network.

The Spectra2 XL3’s high-performance capabilities for controlling multiple protocols in a single scenario and maintaining an extremely robust number of stateful media sessions make it the ideal testing platform for measuring customer QoS in EPC and IMS network environments.
