A method for dormant data session reactivation may include a packet control function ( 118 ) in a radio access network ( 104 ) receiving a first data packet ( 150 ) having a source IP address ( 152 ), where the first data packet has a destination IP address ( 152 ) addressed to reactivate a dormant mobile station ( 102 ) coupled to the radio access network. The packet control function may receive a plurality of subsequent data packets ( 160 ) having the source IP address, where each of the plurality of subsequent data packets has a subsequent destination IP address ( 162, 164, 166 ) and a corresponding time stamp ( 163, 165, 167 ). For each of the subsequent destination IP addresses that are substantially sequential, evaluating an absolute value of a slope ( 270 ) of the difference between the subsequent destination IP addresses that are substantially sequential over a difference in the corresponding time stamps. If the absolute value of the slope is less than a threshold function ( 280 ), denying the first data packet and preventing reactivation of the dormant mobile station by the first data packet.
