Spirent Landslide

VoLTE was devised when operators realized they needed a standardized system for transferring voice traffic over data-only LTE networks. Originally LTE was seen as a completely IP-based system just for carrying data, with operators channeling voice traffic either by turning to legacy 2G/3G systems or by using voice over IP.  But now VOLTE is a complete standard entity in itself with backward compatibility for legacy systems.

 

 I have recently discovered Spirent landslide application for testing voice and data traffic over LTE nodes.

Looks promising.

 

We can emulate either of UE/eNodeB/EPC nodes and/or IMS nodes.

Number of subscribers can be max 1,50000 with normal license

More than 4 million UEs with Ultra Extreme Capacity License

 —Up to 11 bearers per subscriber

The Landslide LTE Gateway Test Application combined with the VoLTE/IMS feature provides a means of testing LTE gateway performance using data traffic, VoLTE calls or both. Integrated support for the Rx interface from the IMS node or SIP Proxy provides a means of testing PGW and/or PCRF operation and performance when using dynamic policy and charging control for dedicated bearer creation, modification and deletion.

 

 

The IMS Node emulation provides a standalone SIP proxy/P-CSCF emulator that can emulate SIP end points or the proxy function and drive the Rx interface to the PCRF.
