Abstract

Method and systems for reporting and analyzing link quality for radiocommunications are described. Use of frame erasure information (e.g., frame erasure rate (FER)) is highlighted. Presentation of frame erasure information can be segregated on a per-connection or per-cell basis, in addition to system-wide output. Moreover, frame erasure information can be correlated with geographical location of a mobile, the mobile's handover status or the equipment type of the mobile station to provide the network operator with a better understanding of quality issues within the network.
