Design and implementation of TETRA call analysis software

TETRA communication standard developed by ETSI has become the leader in the Professional Mobile Radio market, the demand of call analysis software is increasing in the areas of testing, development and network maintenance. But the proprietary signaling of TETRA cannot be processed by most commercial call analysis software, so that we develop TETRA call analysis software to overcome this problem. In this paper, we proposed protocol process architecture based on open source software Wireshark. Some key issues of the development are discussed, including the extraction of call information, the generation of bi-directional navigable Message Sequence Chart (MSC) and network performance measurement. Finally, a test result carried by our call analysis software in an experimental TETRA network is also presented.
