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 eNodeB attributes

• Identification of SON relevant eNodeB and UE Measurements

• Access to and transfer of SON relevant eNodeB and UE measurements

• Transfer of SON relevant eNodeB alarms

Define necessary Interface IRPs

- the automation of neighbour relation lists in E-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.
