TS 32.522: In Release 9, the targets of Load Balancing and Handover parameters Optimization have been defined, and the definitions of common IOCs for Self- Optimization management also have been completed. TS 32.523/32.525: CORBA SS & XML for SON Policy NRM IRP, to be completed by June 2010 (Release 9 exception). TS 32.541: The use case and some requirements of Cell Outage Compensation have been completed and will be finished in Release 10. TS 32.542: Some stage 2 description of Cell Outage Compensation has been agreed and the related NRM IRP definitions will be completed in Release 10.

For specific usage details, refer to the “Typesetting Standard”. 3 LTE Parameter Optimization RequirementsExisting 3GPP Standards Status Automatic optimization of coverage and capacity related parameters in dependency of related KPIs and thresholds. Some requirements have been defined in 3GPP TS 32.521 Release9. Automatic optimization of QoS and GoS related parameters (i.e. adaption of scheduling and / or RACH parameters) in dependency of related KPIs and thresholds. Some requirements of RACH optimization have been defined in 3GPP TS 32.521 Release 9. Automatic optimization of mobility and handover related parameters (i.e. cell individual offsets, down tilts, Event A related parameters) in dependency of related KPIs. The Load balancing and HO parameters optimization related requirements, NRM and targets have been completed in TS 32.521/522 in Release 9. Automatic optimization of cells or services in outage based on an unambiguous detection of this outage. Some requirements and some stage 2 description of Cell Outage Compensation have been defined in draft TS 32.541/542.

For specific usage details, refer to the “Typesetting Standard”. 4 LTE Parameter Optimization RequirementsExisting 3GPP Standards Status Optimization for identified parameters shall be done within a value range, defined by the operator The targets of Load balancing and HO parameters optimization have been defined in TS 32.522, which can be set by the operator within a value range. Optimization shall be done with respect to KPIs and parameters not directly related to the use case KPI (i.e. other KPIs shall not become worse than defined thresholds (e.g. handover optimization shall be done with respect to capacity related parameters resp. KPIs). There is a related requirement (REQ-SO_MM-CON- 11 ) in TS 32.521, but the related IS and solution sets have not been completed. Dependency between KPIs resp. definition which KPIs shall be considered in addition to use case KPI(s) shall be configurable by the operator. There is no related definition in existing standard. Thresholds for start and end point of parameter optimization shall be configurable by the operator. There is a related requirement(REQ-SO_MM-FUN- 1 ) in TS 32.521, the targets of Load balancing and HO parameters optimization and the IOC of SONTargets have been defined in TS 32.522.

For specific usage details, refer to the “Typesetting Standard”. 5 LTE Parameter Optimization RequirementsExisting 3GPP Standards Status Optimization cycle should be configurable (periodically, event-based) There is a related requirement (REQ-SO_MM-CON- 6 ) in TS 32.521, but the related IS and solution sets have not been completed. Support of centralized / decentralized solution Based on the definitions of SONTargets and SONControl in TS 32.522, this requirement has been supported. Degree of automation configurable by the operator. o Optimization cycle completely automated: yes / no o Automated import of optimized settings: yes / no The concept of “Open loop”, which is related with the configuration of the optimization cycle, has been discussed is SA5 and more discussion is needed. There is no related information about the automated import of optimized settings in existing standard. Import / export function of network status with history and fallback solution. There is no related information in existing standard. OSS should provide standardized interfaces to planning tools / processes. There is no related information in existing standard.
