GCF REFRESH enhancements on Interlab TS DEVICE/UICC

Published on 8 April 2016

Interlab Test Solution DEVICE/UICC covers new “REFRESH” test cases according to latest GCF Work Item #230

Services like remote subscription and roaming management of mobile devices require a reliable and correct communication with the integrated UICC. Such actions are handled via the specific USAT “REFRESH” command.

Via its Work Item WI#230, GCF has extended its conformance requirements to sufficiently cover the required “REFRESH” command enhancements for 

  • a 3G session reset (with an IMSI change)
  • a UICC reset (with IMSI change).

The extended test coverage is binding for 3G and LTE USAT conformance criteria and has been implemented in the USAT test specification 3GPP TS 31.124.InterLab Test Solution DEVICE_UICC

In order to cover these new conformance criteria 7layers has extended the coverage of its Interlab Test Solution DEVICE/UICC (Test Platform TP 146). In combination with the R&S® CMW 500 the solution fully covers the new GCF WI#230.

With this extension 7layers once more demonstrates its concept of keeping up with the latest GCF and 3GPP requirements and extending its test solution continuously.

The Interlab Test Solution DEVICE/UICC not only covers the latest “REFRESH” certification test cases. It supports the verification of  a comprehensive number of terminal/UICC interface conformance requirements of GCF and PTCRB for 3G and LTE plus specific certification criteria of China Mobile and Verizon Wireless.
