Patent ID: 11877170
Assignee: ELISA OYJ
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A computer implemented method for evaluating effect of a change in a communications network, the method comprising
receiving a first set of performance indicator values comprising performance indicator values measured over a first period of time before the change in the communications network;
receiving a second set of performance indicator values comprising performance indicator values measured over a second period of time after the change in the communications network;
comparing the first set and the second set to evaluate the effect of the change,
determining a performance threshold based on the performance indicator values of the first set, wherein the performance threshold is determined based on performance indicator values of the first set within a chosen comparison period of the first time period, wherein the first set comprises performance indicator values outside the comparison period;
determining a first performance ratio value based on the performance indicator values of the first set and the performance threshold by comparing performance indicator values of the first set outside the comparison period to the performance threshold;
determining a second performance ratio value based on the performance indicator values of the second set and the performance threshold by comparing the performance indicator values of the second set to the performance threshold; and
providing output based on the first performance ratio value and the second performance ratio value.
