  • Patent number: 10412049
    Abstract: A packet interceptor monitors GTP traffic for control signaling and data plane traffic. The interceptor reroutes a packet by modifying its IP addresses and forwards the packet to a packet data network gateway server. The server receives the GTP-U packet, performs identification based on the synchronized GTP session information, decapsulates the GTP tunnel information from the GTP-U packet and sends to either a proxy server or the destination application server directly. The proxy server performs message filtering, stores packet contents into storage and forwards the packet out to the destination application server. The filtering function of the proxy server can be trained and enhanced with machine learning algorithms. Thus, the proxy server can automatically detect the traffic type and allow or block the packet based on the detection result.
