A method for verifying an operation of a mobile radio communication network is provided, wherein the method comprises sending an Initiation Message from a first network entity to a second network entity, the Initiation Message defining an undo request and comprising an UNDO section defining an undo area, a TRIGGERING_CM section indicating changes to the network, and an ASSISTANCE section; receiving an Assistance-Response Message, the Assistance-Response Message comprising the UNDO section, and an ASSISTED_CM section; and sending an Assistance-Acknowledge Message including an ACK flag and the UNDO section from the first network entity to the second network entity.

Method of verifying an operation of a mobile radio communication network

There are provided measures for verification of configuration actions. Such measures exemplarily comprise detecting a configuration change in a domain, said configuration change comprises at least one parameter change, and said domain comprises at least one cell, repeating, for a predetermined period, an assessment cycle, and deciding, for each respective parameter change of said at least one parameter change, whether said respective parameter change is to be undone, based on a performance change of each cell of said domain which cell is affected by said respective parameter change, wherein said assessment cycle comprises assessing said performance change of each cell of said domain which cell is affected by any of said at least one parameter change.

Scoring method and system for robust verification of configuration actions

It is proposed a method of operating a network by a SON Verification Function (), monitoring a network behavior and verifying a change in network based on the monitored network behavior. The SON Verification Function performs a post-action verification of CM changes and may request from a SON coordinator to undo CM changes.

Verification in self-organizing networks

It is proposed a method for verifying configuration changes in a Self-Organizing Network comprising a plurality of verification areas, in which each verification areas at least one network element is installed. The method comprises observinga configuration change within a verification area affecting one or more network elements; computinga virtual temperature value for the affected network elements, wherein the virtual temperature value indicates a stability state of the network element; distributingthe computed virtual temperature value; receivingthe computed virtual temperature value; triggeringa verification mechanism; and evaluatingthe virtual temperature value of the given verification area.
