Performance Management (PM) is important for operators to manage their radio networks. For the competitiveness of E-UTRAN as a technology it is essential that PM provides the operator an indication of the E-UTRAN Network Elements (NE) performance. End-user perception of service availability and quality should be taken into account.

TS 32.450, TS 32.451 define a set of KPIs for performance evaluation of E-UTRAN NEs' in line with TR 32.816 and the following; KPIs shall:

• show the performance of a E-UTRAN NE, not how the implementation in the NE works;

• be of value to the operator in terms of improving network performance, thereby enabling enhanced end-user perception;

• be based on well described use cases;

• be based on information available on standardized interfaces;

• be standardized either by using a formula or on a high level by using a textual description;

Examples of E-UTRAN KPI categories relevant for standardization:

• Accessibility (see definition in ITU-T E.800);

• Retainability (see definition in ITU-T E.800);

• Integrity (see definition in ITU-T E.800); this contains the connection quality related KPIs;

• Mobility (this contains the Handover related KPIs);

• Utilization (this contains KPIs related to what extent available E-UTRAN resources are utilized);

• Availability (this contains KPIs that indicate the availability of the RAN towards UEs for access).

The use cases for the existing Subscriber and Equipment trace are valid also for eUTRAN and EPC. Therefore the existing Subscriber and Equipment Trace function and IRP need to include the eUTRAN and EPC nodes and interfaces as well as new requirements from TR 32.816 (Study on Management of LTE and SAE).

Work is also needed in RAN3, CT1, CT4.
