Method and apparatus for transmitting a control signal to a self organizing network controller

A non-transitory computer-readable storage device storing a plurality of instructions which, when executed by a processor, cause the processor to perform operations for transmitting a control signal to a self organizing network controller, the operations comprising:

• receiving a change to at least one network element of a communication network from the self organizing network controller;
• determining whether the change to the at least one network element maintains an acceptable level for one or more service quality metrics of the communication network based on a predicted service quality metric calculated using a modeling function, wherein the one or more service quality metrics comprises:
• an accessibility metric and a retainabillity metric, wherein the accessibility metric comprises a probability of successful call establishments, wherein the retainability metric comprises a probability of successful connection terminations, wherein the modeling function is based on one or more of:
• a traffic load variable, a mobility variable and a radio environment variable;
• generating the control signal based on the determining, wherein the control signal indicates to the self organizing network controller:
• to implement the change, to roll back the change when the change has already been implemented, or that the change when already implemented is acceptable;
• and
• transmitting the control signal to the self organizing network controller to cause the self organizing network controller to configure the at least one network element in the communication network in accordance with the control signal.
