Patent 7865944 was granted and assigned to Juniper Networks on January, 2011 by the United States Patent and Trademark Office.
GPRS Tunneling Protocol (“GTP”) packets are intercepted by receiving a GTP tunnel packet, determining whether the GTP tunnel packet is to be intercepted, intercepting GTP tunnel packets if it is determined that the GTP tunnel packet is to be intercepted, and processing the intercepted GTP tunnel packets. Multiple tunnels may be intercepted simultaneously and GTP tunnel packets from different tunnels may be processed differently. Implementations include both inline and offline interception of GTP traffic between SGSN and GGSN.
