Two software options for the MD8475A signalling tester add IMS/ETWS service function tests for LTE smartphones and mobile terminals by upgrading the functions of the MX847570A SmartStudio package while also releasing the MX847570A-080 Extended CSCF option.

The tester is a base station simulator incorporating hardware and software supporting various mobile communications technologies, including LTE, W-CDMA, etc. The SmartStudio software offers a GUI for setting parameters for each communications test.

The functions of the tester have been strengthened by adding the CSCF serve function for controlling IMS services such as VoLTE and SMS over IMS, as well as the public warning service centre function for controlling ETWS services.

Installing the upgraded SmartStudio in the LTE test configuration not only eliminates the need to write complex sequence programs but also supports service function tests of LTE smartphones and mobile terminals offering IMS/ETWS services.

In addition to the SmartStudio upgrade, installing the newly developed Extended CSCF option supports intentional generation of both abnormal status conditions, such as no network response and server error, and quasi-normal status conditions, such as no response from called party and called party busy, at testing of smartphone IMS services.

When communications problems occur in field trials on actual LTE networks, this function can help troubleshoot whether the cause is at the network or is terminal side.
