Implementation and integration of the IrDA Data Protocols into the Telelogic Tau TTCN Suite

Abstract [en]

The use of efficient testing tools can shorten the actual testing time in projects. Ericsson Wireless Research in Dallas is evaluating the use for such tools. One of the areas where it is of interest is AXE service testing. The idea is to test AXE services via cell phones, connected and controlled from a workstation running the test tools. The cell phone in question is the Ericsson CF-888, which has a built in modem which can be controlled via a serial port using simple AT commands. Because of a flaw in the current pre-release of the CF-888 (as of when this is written) full functionality can not be obtained when the phone is controlled with AT-commands directly over a serial link. The solution was to first process the AT-commands with the IrDA protocol stack, and send the IrDA frames as pure data over the serial link. This works because the phone will pass any incoming unknown data to be processed by its internal IrDA protocol stack. The main goal of this thesis was to implement he IrDA protocol stack on a Sun Solaris Workstation to be able to communicate with the CF-888 IrDA protocol stack, and by that control the phone. In this way, full functionality can be obtained, even though the phone is controlled over a serial link. A library of abstract tests for the CF-888 was also created. The purpose of these test steps was to build a basic foundation of test building blocks that future tests can be established from. The idea is simple enough: reuse of code.
