Each base station in the network is served by exactly one VLR, hence a subscriber cannot be present in more than one VLR at a time.VLR data are calculated on the basis of active subscribers in VLR on the last working day (Monday to Friday) of the particular month for which the data is being collected. This data is to be taken from the switches having the purge time of not more than 72 hours
