Method and system for conflict detection in self organization network (SON) functions
First Claim
1. A method for reporting that a performance indicator, associated with a network element in a self-organizing network, is not converging towards its normal expected range, comprising:
- monitoring a performance indicator;
determining, by a processor, that a first performance indicator value is outside of an expected range of values associated with the performance indicator;
defining an acceptable convergence range of values in accordance with a time period for the performance indicator to return to the expected range of values and an allowable deviation beyond the first performance indicator value, the acceptable convergence range converges to the expected range associated with the performance indicator following the expiration of the time period; and
generating a report in response to determining that a second performance indicator value is outside of the defined acceptable convergence range.

Abstract
A system and method for detecting cooperation or conflict between actors in a network made up of self-organizing sub-networks examines parameters such as performance indicators and configuration parameters to determine whether or not different actors are adjusting configuration parameters in a way that is cooperative or conflicting. When a performance indicator is observed to be outside of its expected range, an acceptable convergence range can be defined to give the actors time to adjust and return the performance indicator to its expected range of values. When a performance indicator is detected to be non-convergent, the monitor can alert an operator, or another node, so that appropriate actions can be taken.

9. A monitoring node, comprising:
-
a communication interface for receiving a first performance indicator value and a subsequent second performance indicator value; a processing engine for determining that the first performance indicator value is outside of an expected range of values associated with the performance indicator;
for defining an acceptable convergence range of values in accordance with a time period for returning to the expected range and an allowable deviation beyond the first performance indicator value, the acceptable convergence range converging to the expected range associated with the performance indicator following the expiration of the time period; and
for instructing the communication interface to transmit a report in response to determining that the second performance indicator value is outside of the defined acceptable convergence range. - View Dependent Claims (10, 11, 12, 13, 14)
