1. Accelleran du e2
1.1 Introduction¶
In this section we detail the KPMs that are exposed using the E2 KPM SM from the Accelleran DU.
The KPMs exposed over the E2 interface from the Accelleran DU are aligned with the KPM definition in the 3GPP 28.552 document. Please refer to this document for a detailed description of the KPMs.
1.2 List of KPMs via E2¶
The following table contains a list of KPMs exposed via the E2 interface from the Accelleran DU.
