Wireless customer experience fault analytics system and method of operation

A system for determining whether a fault in a device operating in a network, wherein a plurality of devices are connected with the network, the system comprising:

• a logic tree circuit, wherein the logic tree circuit is coupled to root cause pattern analysis circuits, a crowd parameter determination system, and a device specific characteristics circuit;
• wherein the root cause pattern analysis circuits determine whether the fault is associated with a root cause by comparing device parameters to a plurality of patterns;
• wherein the crowd parameter determination system determines scores associate with the plurality of devices;
• wherein the device specific characteristics circuit associated determines specific characteristics associated with the device,
• wherein the logic tree circuit localizes the fault to the device or to the network based on the match or the non-match to the root cause, the crowd parameters, and the specific characteristics,
• wherein the fault is localized to the device when the root cause is not a match and when an average cell mobile user experience score is less than an network threshold and greater than a device threshold.

A system for determination of a fault signature vector for a device operating in a network, the system comprising:

• a logic tree circuit;
• the logic tree circuit coupled to root cause pattern analysis circuits, wherein the root cause pattern analysis circuits determine whether device parameters of the device match root causes, wherein the logic tree circuit receives a match or a non-match with a root cause from the root cause pattern analysis circuits;
• the logic tree circuit coupled a crowd parameter determination system, wherein the logic tree circuit receives crowd parameters from the crowd parameter determination system and the crowd parameters are determined from a plurality of devices operating in the network;
• and
• the logic tree circuit coupled a device specific characteristics circuit, wherein the logic tree circuit receives specific characteristics from the device specific characteristics circuit,
• wherein the logic tree circuit determines the fault signature vector based on the match or the non-match of the device parameters to one of the root causes, and from a comparison between the crowd parameters and the specific characteristics, wherein the fault signature vector determines whether a fault experienced by the device is associated with the device or with the network,
• wherein the crowd parameter determination system comprises:
• a device mobile user experience score circuit, circuit, coupled to a find bottom percentile circuit, to determine bad mobile user experience threshold, wherein the bottom percentile circuit corresponds to a first probability distribution of the mobile user experience scores,
• a device cell mobile user experience score circuit, coupled to a cell mobile user experience score circuit, to determine cell mobile user experience score vector, and
• an average cell mobile user experience score circuit coupled to the cell mobile user experience score circuit, coupled to a first probability distribution circuit and to a second probability distribution circuit, coupled to a network threshold circuit and a device threshold circuit, wherein the first probability distribution circuit is related to good average cell mobile user experience scores and the second probability distribution is related to bad average cell mobile user experience scores.
