Rhode & Schwarz has introduced software that means two of its protocol testers can be used for analysing GSM to UMTS call handover.
The R&S CRTU-WA03 software option makes it possible to design signaling tests that simulate different UMTS-to-GSM handover scenarios. Both voice and data transmission can be tested. The software is the expansion of the R&S CRTU-W protocol tester for UMTS.
Research and development laboratories of mobile phone companies and network providers need tools to test the interoperability of 2G to 3G networks in custom signaling scenarios.
Users can perform such tests with the help of the GSM/GPRS/EDGE function library of the R&S CRTU-G protocol tester, which was integrated into the UMTS medium level application programming interface (MLAPI) as C++ modules.
As with the C++ MLAPI, these new modules can also be used in the GERAN protocol stack means of generating signaling scenarios at layer 3. All underlying channel structures are taken into account.
