Test agents and proxies using client simulation and server emulation

Mobileum’s dsTest offers server emulation and client simulation capabilities for comprehensive testing of 3GPP 4G core network interface functionality and performance. By selecting the interfaces required to accomplish your testing goals, a network element is surrounded with client simulators that simulate client activity or provision a server emulator with the interfaces necessary to support end-to-end testing.  Our solution tests 5G, LTE, EPC, eMBMS, SMS, WLAN Offload, and VoLTE networks, and gathers Big Data to support the identification of patterns and provide new business opportunities, revenues, and efficiencies in network operations.

Mobileum dsTest is a software product that provides an environment that supports the goals of network function virtualization (NFV) and Software-Defined Networking (SDN).

Lab and performance testing for faster LTE deployment

Focused on protocol development, test, and traffic analysis, Mobileum's dsTest solution provides performance and functional testing tools intended for the rapid deployment of protocols stacks.   dsTest is a software platform designed to take advantage of the latest COTS processor technology to provide very high performance and capacity products, which cost-effectively scale to hundreds of millions of subscribers and 1.2 million transactions per second or more.

dsTest provides solutions for testing/emulating subscriber management, policy, and charging, Diameter Routing, DPI, Big Data, SMS, GTP, and IMS nodes with the 3G/4G/5G mobile packet core.  We provide customized variants of standard protocols or full custom protocol/applications on our flexible platform.  We also offer analysis of Diameter and GTP traffic with our dsAnalyzer tool.
4G core and VoLTE testing

Simplified Voice over LTE testing 

Mobileum’s dsTest emulates the PCRF, PGW, and P-CSCF to simulate VoLTE subscriber activity through the DRA, initiating procedures with the PCRF over the Gx and Rx interfaces.  It can host thousands of PGWs and CSCFs attempting to connect to multiple PCRFs, requiring the DRA to route transactions for specific subscribers to the appropriate PCRF. 

A shared subscriber database enables the PCRF to be provisioned with the same profiles that supply the emulated PGW and CSCF with subscriber identities, service definitions, SmartAVPs, and the SmartEvents. By using a common repository it keeps configured and dynamic subscriber information synchronized across all devices and applications. Our simplified testing:
  • Establish IP-CAN session 
  • Activate dedicated bearer
  • Terminate dedicated bearer
  • Terminate IP-CAN session

5G Performance Testing
5G was specifically designed to meet IoT needs, whereas 2G, 3G, and 4G were never developed with IoT in mind. It brings two key attributes which neither NB-IoT nor LTE can deliver; they are: low latency and ultra-reliability. Know more about our 5G testing solutions and how they support IoT environments.
