Patent ID: 7844443

Claim:
A method for modeling a subscriber network experience to a network comprising: receiving, at a computer, a plurality of subscriber metrics associated with a subscriber's access to the network, the metrics measuring quality of service for the subscriber experience with the subscriber's access to the network; and modeling, at the computer, the subscriber experience by applying a transformation to the plurality of subscriber metrics to produce a set of subscriber experience data, where each element of the subscriber experience data quantifies an aspect of the subscriber experience, wherein the plurality of subscriber metrics comprises a plurality of service metrics and a plurality of network degradation metrics, the method further comprising: translating the plurality of subscriber metrics into at least one subscriber space vector; translating the plurality of subscriber metrics into at least one degradation space vector; and modeling the subscriber experience by applying a series of transformations to the at least one subscriber space vector and to the at least one degradation space vector to produce a set of subscriber experience data, wherein the at least one subscriber space vector comprises a plurality of subscriber space vectors, and the at least one degradation space vector comprises a plurality of degradation space vectors, and the modeling further comprises: applying a scaling operation on at least a portion of the service space vectors to produce a plurality of scaled service space vectors; applying a scaling operation on at least a portion of the degradation space vectors to produce a plurality of scaled degradation space vectors; combining the scaled degradation space vectors to produce a degradation space matrix; multiplying the scaled service space vector and the degradation space matrix to produce a translated service space vector; applying a frequency transform to the degradation space vector to produce a degradation frequency vector; and calculating the dot product of the translated service space vector and the degradation frequency vector.
