A network node device in a communication system in which a data packet stream is received in the network monitoring node device having a Paging Message packet that is sent from a network node device. The identity of a User Equipment (UE) associated with the received Paging Message packet is then determined. A determination is then made if Paging Message information associated with the determined UE is stored in memory associated with the network monitoring device, whereupon the received Paging Message packet is filtered from the received data packet stream in the event previous Paging Message information was determined to be associated with the determined UE device in the memory. Additionally, Paging Message information is stored in the memory in the event there are no Paging Message packets stored in the memory associated with the determined UE device.
