METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR VALIDATING LOCATION UPDATE MESSAGES

Abstract:

The subject matter described herein includes a methods, systems, and computer readable media for validating location update messages. One method includes receiving, by a signaling firewall from a non-home network, an ingress location update request message related to a mobile subscriber, querying a directional state database to obtain predicted country trajectory data associated with the mobile subscriber, and comparing the obtained predicted country trajectory data with country code information included in the ingress location update request message. The method further includes validating the ingress location update request message if the predicted country trajectory data and the country code information match.
