As the 3GPP R15 specifications become more stable, NEMs and Carriers are conducting more Proof of Concept (PoC) tests to evaluate every aspect of this new network architecture. To aid this tremendous effort, release 17.5 continues Landslide’s strategic feature set alignment by (1) upgrading all test cases to 3GPP Rel.15 Sept, 2018 specifications version and (2) introducing enhancements for ‘True 5G’ testing. In addition to the existing AMF and UPF testing capabilities, Landslide now enables critical core network testing of the Session Management Function (SMF) in isolation via the new SMF Nodal test case. Furthermore, Landslide 17.5 continues to expand the 5G Service-based testing feature set by adding the NSSF test case and node emulator to help customers validate the dimensioning and configuration of 5G’s native network slicing.

Other key areas of mobile network testing have also been enhanced: Landslide 17.5 adds support for NB-IoT Robust Header Compression and NB-IoT OTDOA, R14 CUPS Lawful Intercept and encrypted IMSIs for ePDG and/or AAA testing.

Feature Enhancements

5G Evolution

At Spirent, we know delivering first to market technologies for 5G requires test tools that align with and even anticipate the release of new specifications. We are the partner of choice for Vendors and Carriers developing and testing the next generation of wireless technologies.

R17.5 is the fourth Landslide release with True 5G (5G SA) core test cases. New use cases include:

  • SMF Node testing and emulation
  • NSSF Node testing and emulation
  • R15 September Specification updates
  • IPv4, IPv6 and dual-stack IPv4v6 PDU Sessions
  • Paging support
  • Voice over 5G support
  • Support for Command Mode/Sequencer for 5G AMF Nodal test case

More 5G core functionality plus additional node testing and emulation will be added continuously in the upcoming releases.

Additionally, 17.5 continues enhancing Landslide’s 4.5G testing capabilities by adding new use cases and features including:

  • NB-IOT - OTDOA support
  • NB-IOT - Robust Header Compression
  • NB-IOT - Linked S6a and S6t support on HSS node
  • CUPS - Lawful Intercept Testing
  • MC-PTT (see VoLTE/IMS section)


Landslide continues its expansion in direct IMS/Voice over IP testing, while maintaining the unparalleled voice and video over LTE testing capabilities. In this respect, Landslide 17.5 introduces the following enhancements:

  • MCPTT - Application Server as SUT testing
  • MCPTT - Floor control testing scenarios
  • Transport type (UDP, TCP) independent SIP messaging

ePDG and AAA Testing

Support of IMSI encryption in EAP payload for AAA testing and/or emulation in ePDG scenarios.
