The present document describes the requirements and architecture for the Self Organizing Network (SON) functions within the OAM system. SON includes: Provision of infrastructure for SON, in the OAM system

• Enabling SON operations;
• Provide SON capabilities (each of which can either be distributed or centralised) within the OAM infrastructure, including their management;
• Access to SON relevant attributes;
• Identification of SON relevant Measurements;
• Access to and transfer of SON relevant measurements;
• Transfer of SON relevant alarms.

Define necessary Interface IRPs

• the automation of neighbour relation lists in E-UTRAN, UTRAN and between different 3GPP Radio Access Technologies,
• self establishment of a new eNodeB in the network,
• self-configuration and self-healing of eNodeBs,
• automated coverage and capacity optimisation,
• optimisation of parameters due to troubleshooting,
• continuous optimisation due to dynamic changes in the network,
• automated handover optimisation,
• optimisation of QoS related radio parameters.

The SON concept and architecture are described in clause 4. The high-level requirements for SON are defined in clause 5. Use cases for SON are described in clause 5.
