Distributed SON (D-SON) functions are important tools for network optimization. The present document studies potential areas where performance of automated D-SON functions can be improved by OAM aspects. It is aimed that such performance enhancements would help network operators in improvement of network efficiency without significant additional expenses.

The present document aims the following:

• Identify whether Distributed SON (D-SON) Mobility Load Balancing (MLB) as currently specified in 3GPP can be improved;
• In case potential areas of improvement are identified, propose possible solutions.
