Method and server for dynamically determining a reference signal (RS) power boost level

摘要

A method and application server for dynamically determining a Reference Signal (RS) Power Boost level in a radio telecommunication network. The application server may be a Self-Optimized Network (SON) application server configured to received network performance information from Performance Management (PM) counters and configuration information from a configuration database server. The application server monitors a plurality of network Key Performance Indicators (KPIs), compares the KPIs to associated thresholds, and derives and assigns values to KPI threshold factors. The server calculates a scaling factor based on values of the KPI threshold factors, and calculates a dynamic RS Power Boost level by applying the scaling factor to a baseline RS Power Boost level.

1. A method performed in a Self-Optimized Network (SON) Application Server for dynamically determining a Reference Signal (RS) Power Boost level in a radio telecommunication network, the method comprising:
monitoring a plurality of network performance indicators for a monitoring time interval; calculating a scaling factor based on values of the plurality of network performance indicators measured or computed during the monitoring time interval; and calculating a dynamic RS Power Boost level by applying the scaling factor to a baseline RS Power Boost level; wherein calculating the scaling factor based on values of the plurality of network performance indicators includes:
evaluating the plurality of network performance indicators to determine a corresponding plurality of performance threshold factors, wherein each given network performance indicator is evaluated to determine whether the value of the given network performance indicator during the monitoring interval causes an associated threshold to be exceeded;when the associated threshold is exceeded, assigning a first value to a performance threshold factor corresponding to the given network performance indicator;when the associated threshold is not exceeded, assigning a different, second value to the performance threshold factor corresponding to the given network performance indicator; andcalculating the scaling factor based on the assigned values of the plurality of performance threshold factors corresponding to the plurality of network performance indicators.
