has introduced two new software options for its popular MD8475A signalling testers, adding IMS/ETWS service function tests for LTE smartphones and mobile terminals while also releasing the new MX847570A-080 Extended CSCF option.
MD8475A signalling testers are base station simulators that incorporate hardware and software, supporting various mobile communications technologies, including LTE and W-CDMA, among others.
IMS/ETWS service function tests have been added by upgrading the functions of the MX847570A SmartStudio package. This software provides an easy-to-use GUI for setting parameters on MD8475A signalling testers for each communications test.
With this new introduction, Anritsu has strengthened the functions of the MX847570A package by adding the CSCF Serve function for controlling IMS services such as VoLTE and SMS over IMS, as well as the Public Warning Service Center function for controlling ETWS services.
Installing the upgraded MX847570A SmartStudio in the LTE test configuration of the MD8475A 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 MX847570A 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, as well as 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 terminal side.
Anritsu notes that IMS/ETWS services are expected to become increasingly common as a key LTE application.
