  • Method for measuring network performance parity
    Patent number: 7907536
    Abstract: A method for measuring network performance parity includes the steps of computing a call completion ratio for at least one network provider, and determining whether the call completion ratio passes a first test. These steps may further include computing a first call completion ratio for a first network provider, a second call completion ratio for a second network provider, a difference between the first call completion ratio and the second call completion ratio, and a variance for the difference. The method also includes the step of assessing whether a second test is determinate if the call completion ratio does not pass the first test, by determining whether the variance is greater than a variance cutoff. In addition, the method includes the step of assessing whether a call completion ratio passes the second test, if the second test is determinate, by determining whether the difference is greater than a threshold.
