The E-UTRAN system is defined by 3GPP with different Network Elements from the UTRAN, and the interfaces between Network Elements and signalling over the interfaces are also different from the UTRAN. The performance measurements of the UTRAN are not applicable to E-UTRAN.

The E-UTRAN system needs to be managed. Performance measurements are the basic data for Performance Management (PM), and also the supporting data for the SON (Self Organizing Networks) functionalities.

Each of the E-UTRAN performance measurements shall be motivated by the use case or requirement for PM or SON. For PM, the use case or requirement for each proposed performance measurement is in the scope of this WI. For SON, the use case or requirement is out of the scope of this WI. This WI defines only the E-UTRAN performance measurements which are clearly stated as mandatory over Itf-N. In case of SON use cases, requirements or solutions are covered by other SA5 WIs on SON (UID_390004).

The E-UTRAN architecture and capabilities evolved from those defined for UMTS. The management of the E-UTRAN system should also evolve from that for UMTS. In particular, the PM IRP is reused for E-UTRAN Performance Management. So the performance measurement definition for E-UTRAN is managed via PM IRP, i.e. the performance measurement definition has a consistent format which can be collected and monitored via PM IRP.

TS 32.425 defines E-UTRAN performance measurements to be transferred over Itf-N supporting PM or SON:

1. Only the performance measurements necessary to be transferred over Itf-N are in the scope of this WI; but includes if necessary E-UTRAN performance measurements for other management interfaces (e.g. Itf-P2P).

2. This WI covers the performance measurements for macro eNodeB and home eNodeB.

3. The E-UTRAN performance measurements are defined in a top-down approach. Each measurement definition has at least one supporting use case or requirement agreed before being inserted into the TS. For PM purpose in E-UTRAN, the related use case or requirement was agreed under this WI. For SON purpose in E-UTRAN, this WI only defines the related E-UTRAN performance measurements which are clearly stated as mandatory over Itf-N in the SON use cases, requirements or solutions, which are covered by other SA5 WIs on SON (UID_390004).

The performance measurements have identical characteristics as those defined for other network domains such as UTRAN, CN, IMS, etc. The performance measurement definition follows the same concept and requirements addressed in TS 32.401. The performance measurement definition follows the same definition and template addressed in TS 32.404.
