A method of multi-protocol call trace on GPRS Gb and Gr interfaces of a GSM network
uses distributed processing. Probes are situated at locations where measurements
are desired in a monitored mobile network, such as at Gb and Gr interfaces, and
are connected in a non-intrusive manner to the mobile network. A remote server
is coupled to each probe over a local area network (LAN) to process data as it
is acquired by the probe. The probe and remote server are coupled to a central
server via a wide area network (WAN), as are client servers. The remote servers
manage the probe data (packet data units-PDUs) in real time to create appropriate
transactional and raw data indices that are stored locally with the PDUs. Call/procedure
trace applications are initiated from the client servers and disseminated by the
central server to the remote servers. The remote servers provide results back to
the central server which correlates the results and disseminates them back to the
remote servers to obtain additional results for correlation. The results from the
central server are provided to the client servers which display or visualize the results.
