2. Executive Summary
This document is an official BSS Network Modernization KPI Acceptance Report which indicates that the Implementation Procedure
has been performed and the KPI measurement result has fulfilled the acceptance value. Ericsson is glad and proud to conclude that
since the Modernization Period, an impressive improvement to Telkomsel’s network performance has been achieved. There were a
lot of activities that had been carried out to improve the network performance.
These measurements were collected, post processed and analyzed according to the agreed process as specified in the BSS
Network Modernization KPI Acceptance Methodology / Procedures. For a description of the used equipment, the details for particular
measurements and the process for data collection and processing please refer to the above-mentioned document. This KPI
Acceptance Report is made according to the agreement document describing the area and the applicable design rules and values.
This document will be submitted in Hardcopy and Softcopy included supporting data.
