Description   Landslide 17.5 is now available for download on the Spirent customer support website. 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 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. Get all the details - Landslide 17.5 Release True 5G Test Cases R17.5 is the fourth Landslide release with True 5G core test cases. New use cases include:  SMF Node testing and emulation NSSF Node Testing and Emulation R15 September Spec 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.  3GPP R13/R14 4G Enhancements 17.5 continues enhancing pre-5G or R13/R14 4G testing capabilities as follows: MCPTT - Application Server as SUT Testing MCPTT - Floor control testing scenarios NB-IOT - OTDOA support NB-IOT - Robust Header Compression NB-IOT - Linked S6a and S6t support on HSS node CUPS - Lawful Intercept Testing ePDG and AAA Testing Support of IMSI encryption in EAP payload for AAA testing and/or emulation in ePDG scenarios.   VoLTE/IMS Landslide continues its expansion in direct IMS/Voice over IP testing, while maintaining the unparalleled voice and video over LTE testing capabilities. Landslide 17.5 introduces: MC-PTT Enhancements Transport type (UDP, TCP) independent SIP messaging
