 transmit to the wireless device a measurement configuration; 
 receive measurements taken by the wireless device based on the measurement configuration; 
 determining an occurrence of the monitored event based at least in part on the received measurements from the wireless device and a location of the wireless device in a radio map; 
 transmitting a notification indicating the occurrence of the monitored event; and 
 transmitting to the wireless device a reconfiguration parameter based at least in part on the occurrence of the monitored event. 
   
     
     
         13 . The network apparatus of  claim 12 , wherein the monitored event is a number of unlocated access points located in a particular area of the radio map exceeding a threshold.
