Abstract: A method for detecting user triggered call drops includes identifying one or more user terminated calls from a plurality of monitored calls. Signaling information associated with the identified user terminated calls is correlated with media channel information associated with the identified user terminated calls. A determination is made if termination of the one or more of the identified user terminated calls is related to quality of media across corresponding media channels. A predefined cause code is assigned to the one or more of the identified user terminated calls, in response to determining that the termination of the one or more of the identified user terminated calls is related to the quality of media across the corresponding media channels.

Abstract: A system and method to identify a call end associated with a problem that caused failure of an internet protocol-based call. The method includes accessing a first call detail record (CDR) set including at least one CDR associated with a first call end of the failed call, determining from the first CDR set indicators of failure attribution of the failed call, determining whether fault for failure of the failed call is attributed to the first call end based on the indicators of failure attribution; outputting an indication that the fault is attributed to the first call end if it was determined that the fault is attributed to the first call end, and outputting the indication to indicate the first call end is acquitted of the fault if it was determined the fault is not attributed to the first call end.

Abstract: A method for monitoring, detecting and reporting the impact of handovers on the quality of experience for one or more users in a mobile cellular network includes collecting, from a plurality of mobile network elements, session records specifying data about sessions handled by two or more mobile network elements. A session record comprises a signaling portion and a media portion. Each session includes two or more session segments. Session segments having session media gaps are identified from the media portions of the collected session records. At least some of the session media gaps are associated with a handover procedure between two mobile network elements. A plurality of performance metrics related to handover procedures in the identified session segments are calculated and stored. An interactive graphical representation of the stored performance metrics is rendered to a user via a graphical user interface.
