The MX785201A W-CDMA/UMTS Protocol Test System (PTS) software, when used with an MD8480C and linked to a prototype or actual 3GPP wireless device, enables Layer 2 and Layer 3 Test Procedures to be run for verification and subsequent validation of W-CDMA/UMTS wireless device signaling protocol stacks using TTCN. It provides a framework for controlling and executing test procedures on the Anritsu MD8480C W-CDMA Signaling Tester (Base Station simulator). The PTS system consists of software components that run on a PC. It executes TestStand™ test sequences made up of calls into a library of TTCN test cases through which can be defined:

• Sequences of Layer 3 messages and expected responses
• Layer 3 to Layer 2 service primitives to trigger specific Layer 2 procedures, or to configure Layer 2 operation
• Layer 3 to Layer 1 service primitives to configure and initiate Layer 1 operation
• Service primitives to and from user-provided code

The PTS supports multiple 3G cells enabling Soft and Hard Handover tests to be carried out. In addition, inter-system Handover tests from GERAN to UTRAN, and vice versa are supplied.
