METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR CONDUCTING A VELOCITY CHECK FOR OUTBOUND SUBSCRIBERS ROAMING TO NEIGHBORING COUNTRIES

A method for conducting a velocity check for outbound subscribers roaming to neighboring countries includes receiving, by a network gateway associated with a home country from an MSC associated with a neighboring country, an ingress signaling message related to a mobile device roaming in the neighboring country, sending, to an HLR in the home country, an interrogation request message containing a mobile subscriber identifier, and receiving an interrogation response message containing age of location information and cell identifier information corresponding to the mobile subscriber identifier. The method further includes utilizing the cell identifier information and a country code identifier included in the ingress signaling message to determine two latitude-longitude positions, determining an estimated transit time of the mobile device using the two latitude-longitude reference positions, and comparing age of location information with the estimated transit time to determine if the ingress signaling message is to be forwarded to the HLR.
