Efficient block error rate evaluation in a femto cell network

摘要

System(s) and method(s) are provided to evaluate uplink or downlink block error rate (BLER) performance in a femto cell network. Data on uplink or downlink communication of data blocks for a set of femto access points (APs) is aggregated, wherein the selected is a fraction of a larger set of provisioned femto access points. The set of femto APs can be selected based at least in part on various criteria which can ensure that operation of the selected set of femto APs is a statistically meaningful representation of operation of the larger set of femto APs. Composite alarm thresholds facilitate triggering alarm(s) when a predetermined portion of the aggregated data reveal a BLER failure condition. Composite thresholds can be generated through analysis of aggregated uplink/downlink (UL/DL) BLER data for a set of femto APs.
