scope:

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.
