General

Previous Releases

Changes made in previous releases are listed in the following topics:

 

Command Mode

Command mode Test Activity allows you to control and dynamically alter the UE’s mobility procedure or next data transmission during test execution. The command mode test case, also allows you to have manual or automated control of the mobile subscriber's actions. You may specify the operation to be performed on a specific mobile subscriber, the type of events to execute (example, Attach, Detach, Handover, Add Bearers/contexts, Delete Bearer/Contexts, etc.), and the timing of the event during test execution.

Landslide 11.6 supports Command mode in GGSN Nodal, MME Nodal, OCS Node, SGW Nodal, PGW Nodal, UMTS Nodal, and PCRF Node testing.

CSV-TDF Editor

Use TDF-CSV Editor to create Test Data Files to provision unique, non-sequential/complex list values for some parameters.

DMF - Traffic Mix

The Traffic Mix and Payload Throughput window allows you to edit a DMF group by type and percentage of throughput. You may change the throughput in one of the following two ways:

You may edit Traffic Rate/Mix and Throughput at the table/pie chart level and are not required to open each DMF to make the change.

LTE Enhancements

Landslide 11.6 LTE support adds enhancements to MME Nodal, SGW Nodal, and PGW Nodal testing.

Please see the Release Notes for a list of all LTE features and enhancements.

Supports Any-to-Any I-RAT Handover scenarios

MME nodal supports ability to perform handovers from a range of enodeBs to a range of SGSNs/RNCs for 3G and a range of BSSs for 2G. This enables emulated UEs to handover to different SGSNs/RNCs/BSSs and even hand back to different enodeBs when performing I-RAT handovers.

TCL Scripting API

Landslide 11.6 Tcl-based API allows total control of the Landslide system via the Tcl interface. All the capabilities available via Landslides GUI are available via Landslide’s Tcl API.  

In addition, you may also save the existing test sessions, DMFs, and/or MEs as Tcl file. See also Save As Tcl.

Voice Over LTE (VoLTE)

The Landslide VoLTE implementation supports testing of in LTE ePC as a whole or in part with a two-arm configuration. In addition, the implementation also supports one-arm configuration with the IMS Core Network and combined ePC / IMS CN for VoLTE support.  

Release 11.6 includes VoLTE: IR-94 Dual dedicated Bearer Video support

SGW Nodal supports both IR.92 Voice (single dedicated Bearer) VoLTE scenarios and IR.94 Voice + Video (dual dedicated Bearer) VoLTE scenarios.
