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 17.6 continues Landslide’s strategic feature set alignment by (1) upgrading all test cases to 3GPP Rel.15 Dec, 2018 specifications version and (2) introducing enhancements for ‘True 5G’ testing, among many others: SUCI encryption, multi-PDU Session per UE capabilities, Xn handovers and native network slicing in AMF Nodal test case. Furthermore, Landslide 17.6 continues to expand its feature set in other key areas of mobile network testing: Landslide 17.6 adds support for Secure User Plane Location (SUPL) Server testing, generic IMS Trunk Interface Emulation and IMS call distribution across multiple P-CSCFs.

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.

R17.6 is the fifth Landslide release with True 5G (5G SA) core test cases. New features include:

  • R15 December 2018 Specification updates
  • Native Network Slicing configuration and re-routing
  • Multi-PDU Sessions per UE
  • SUCI encryption to protect identity
  • Local Area Data Network (LADN) support for testing and emulation on MEC
  • Fireball High Performance Data support

Additional functionality will be added continuously over the next few releases, including IRAT 4G-5G testing.


Landslide continues its expansion in direct IMS/Voice over IP testing, while maintaining the unparalleled voice and video over LTE testing capabilities. Landslide 17.6 introduces the following enhancements:

  • New Generic IMS Trunk Interface to create any IMS SIP interface (eg; Mg and Mj interfaces), or modify existing ones.
  • Capability to conduct IMS call distribution across multiple P-CSCFs.
  • Configurable proxy mode IMS Node behavior via SIP Message editor.
  • Supplementary Service Testing enhancements.
