Abstract:
An infrastructure-based mobililty determination module (MDM) receives multiple measurement reports from the MS and, for each received measurement report, stores values corresponding to values included in the report that are associated with measurements of parameters associated with received signals, wherein each stored value is stored in association with a wireless access node sourcing the corresponding signal. For each of one or more pairings of received measurement reports, the MDM then determines a signal parameter measurement change value corresponding to a change from the signal parameter measurement values associated with a first measurement report of the pairing to the signal parameter measurement values associated with a second measurement report of the pairing. Based on the one or more signal parameter measurement change values, the MDM determines an average signal parameter measurement change value and, based on the average signal parameter measurement change value, determines a mobility of the MS.
