Plate-forme d'acquisition d'evenements asynchrones generes par l'interface radio d'un commutateur de telephonie mobile

The TDMA ("Time division multiple access") mobile telephony systems are specified by various standards; the North American version of TDMA is specified by the ANSI-136 standard. One of the key parts described by that standard is the radio interface. In fact, among other elements, these specifications present a set of messages and procedures that allow mobile terminals to establish telephone connections. Ericsson Company implements ANSI-136 on its general-purpose AXE-10 digital switches.;In our project, we have developed and prototyped a flexible platform to acquire asynchronous events which are generated by the AXE-10 radio interface. These events are, in fact, generated by various modules of the controlling software. Their sequences represent the architecture and performance of the ANSI-136 implementation. These events may be analysed in order to monitor or optimise the radio interface performance. Taken separately, the amount of information they provide is very small. This is why our platform has to rebuild their sequences for each call in progress in order to extract information of interest. Our main goal is to provide a foundation for some advanced analysis applications running in "near" real-time. (Abstract shortened by UMI.)...
