Abstract
A plurality of data packets is received from a wireless communication system. At least one of SIP signaling messages and S1-AP signaling messages associated with calls being made or attempted in the wireless communication system are analyzed for a specified time period to identify one or more dropped calls. At least one of SIP signaling error codes and S1-AP signaling cause codes associated with the identified dropped calls are analyzed to identify one or more call drop reasons. An ASI data set is generated based on the analysis of the at least one of the SIP signaling messages and the S1-AP signaling messages and based on the analysis of the at least one of the SIP signaling error codes and the S1-AP signaling cause codes.
