03 | Keysight | E6966B IMS-SIP Network Emulator - Technical Overview
Voice, video, and SMS over IMS
The E6966B is designed specifically to
test UE voice, video, and SMS services
operating over an IMS core. It provides full
client and server implementation, allowing
you to perform end-to-end functional test.
While IMS-SIP is independent of any spe-
cific radio access technology, the E6966B
IMS-SIP network emulator is intended
for use with the Keysight E7515A UXM
and E5515C/E 8960 Series 10 wireless
communications test set acting as base
station emulators. These test sets provide
over-the-air network connection between
the UE and the IMS-SIP infrastructure and
have the flexibility to emulate a range of
different network conditions, enabling UE
performance to be verified in a controlled
laboratory environment.
Key server features
–– Establishes client-to-client connection
–– 3GPP IMS extensions
–– IMS AKA, AKAv2, and MD5 authentication
–– IPv4 and IPv6 support
–– IPsec support
–– Supplementary service support
–– Multi-party call support
–– API for test automation
–– E.911 support
–– PRACK and preconditions
Already established in the world of 2G, 3G,
and 4G performance and conformance
test, these leading UXM and 8960
test sets now support IPv4 and IPv6
addressing and the required security
configuration to implement functional
test. The UXM includes an emulation of
the evolved packet core (EPC)—an all-IP
mobile core network required by 3GPP in
the standards for LTE.

The IMS-SIP server responds to requests
received from the UE and initiates SIP
operations including: re-registration,
de-registration, and SIP message
transmission. Registration may be with
or without authentication, PRACK, or
preconditions.
The server can also be configured for
alternative response testing. That is, it
can respond in a specific manner that is
atypical to a given SMS message received
from the UE.
