For example, a click on the "Zoom" button, as shown in Figure 1, willextract all messages that belong to one particular call, even from a largerecording. This saves time and is as easy as it could be. Figure 1. Click on the Zoom button to extract all messages. A sophisticated filter configuration dialogue, as shown in Figure 2,enables the user to select messages according to a certain criteria (e.g.containing a certain IMSI, etc.). Figure 2. Filter dialogue allows user to select messages accordingto certain criteria. Decoding down to bit-level for all parameters is essential for troubleshootingand problem analysis, as shown in Figure 3. Figure 3. All parameters can be decoded down to the bit-level. Figure 4. Convenient trouble shooting: cdma Multi-Interface Calltracecaptures messages from different interfaces belonging to the same transaction K1297-G20 The K1297-G20 features protocol monitoring, simulation, and emulation.The instrument's hardware, software, and user interface are based on theK1297-G20 Monitor, which makes it easy for previous K1205/K1297-G20 Monitorusers to adapt to the G20. Capabilities in the K1297-G20 allow applications that are particularlyvaluable for Network Installation and Commissioning in the field. Network Element Emulations for Replacing of Real Equipment Network Element Emulations on the K1297-G20 are designed to allow networkelements (such as MSC, HL, etc.) to be replaced by the Emulation for testingpurposes. All parameters - for example, phone numbers, IMSIs, and more - are configuredthrough menus. Once activated, the Network Element Emulation will automaticallyrespond to incoming messages and/or initiate calls and procedures. Outgoingcalls or procedures can be initiated interactively with a mouse click,or with the help of a simple script interface by defining specific callscenarios, as shown in Figure 5. Figure 5. Configuration dialog for a Network Element Emulation. MBS/MSC Tools for Detail Level Testing and Troubleshooting The MBS (Message Building System) and MSC (Message Sequence Chart Tool)allow users to graphically design and modify Test Cases. Users have full control over message flow and message content. Virtuallyany equipment behavior (correct or faulty) can be simulated with the MBS/MSCtools, making it particularly useful for detail level testing or troubleshooting. The MBS is used to create messages and edit their parameters. Variablescan be used to handle parameters dynamically. Figure 6 illustrates howthe MBS and MSC tools are used. Messages are built by selecting the MessageType and Parameters (IEs) from menus. Figure 6. Message Building System (MBS) and Message Sequence ChartTool (MSC) displays. As shown in Figure 7, the MSC is used to define the message flow of atest case. The messages (indicated by arrows in the chart) are definedwithin the MBS. Figure 7. Message Sequence Chart Tool displays. CDMA2000 System Architecture Figure 8 illustrates the CDMA2000 system architecture. Figure 8. CDMA2000 architecture diagram. A1 Interface The A1 interface is the Interface between the BSS (Base Station Subsystem)and MSC (Mobile Switching Center) for the circuit-switched side of theCDMA2000 network, as shown in Figure 9. Figure 9. A1 Interface testing diagram.

TheseTest Cases are particularly useful for troubleshooting or detail-leveltesting since any equipment behavior can be simulated. A Voice Path Verification feature ensures that B-channels are switchedcorrectly. The user may modify or add Test Cases as needed (message content as wellas message sequence), using the MBS and MSC tools. The time needed forrecompiling and reloading a test case is very short (<1 min). MBS/MSC Test Suite for A1 Interface The following procedures are covered in the predefined test suitefor testing the BSS and MSC side: Location Registration Mobile Originated Call (MOC) Mobile Terminated Call (MTC) Call Clearing (MO and MT) Call Waiting Message Waiting Indication (MS Idle and in Traffic) SMS (MS Idle and in Traffic) Voice Path Verification A10/A11 and P-H Interface See Figures 10, 11, and 12.
