Scalable and iterative deep packet inspection for communications networks
First Claim
1. A system, comprising:
- a home network including a multimedia subsystem, a home packet data network gateway (PGW), anda home serving-call session control function (S-CSCF);
an Internetwork packet exchange; and
a visitor network in communication with the home network over the Internetwork packet exchange, the visitor network having an intercept area having an intercept probe, a local packet data network gateway (PGW) and a local proxy-call session control function (P-CSCF);
a diameter edge agent that monitors signaling traffic in the visitor network received from the home network;
a targeting system attached to and in communication with the diameter edge agent, wherein the targeting system redirects the signaling traffic from the home PGW to the local PGW by changing the an access point name (APN) from the home network to the visitor network;
and the intercept probe is disposed between and in communication with the local P-CSCF and the home S-CSCF, wherein the intercept probe copies and processes the signaling traffic in the intercept area.

Abstract
Systems and methods for scalable and iterative deep packet inspection for communication networks are disclosed. According to one embodiment, a system comprises a home network and a visitor network in communication with the home network over an Internetwork packet exchange. The visitor network may have an intercept area with an intercept probe, a local packet data network gateway (PGW) and a local proxy-call session control function (P-CSCF). The system further includes a diameter edge agent that monitors signaling traffic in the visitor network passing to and from the home network. The system also has a targeting system in communication with the diameter edge agent that redirects the signaling traffic from the home PGW to the visiting PGW.

9. A method, comprising:
- monitoring, with a diameter edge agent device, signaling traffic passing between a mobility management entity in a visiting network and a home subscriber server in a home network;
routing, with the diameter edge agent device in the visiting network, the signaling traffic to a targeting system attached to the diameter edge agent device; routing, with the targeting system, the signaling traffic to an inspection area of a visitor network by a first mode or a second mode, wherein the first mode includes relaying the signaling traffic to the inspection area of the visitor network and the second mode includes modifying routing information of the signaling traffic; inspecting, with an inspection probe disposed in the inspection area of the visitor network, the signaling traffic; and copying and processing, with an intercept probe, the signaling traffic in an intercept area, wherein the intercept probe is disposed between and in communication a local proxy-call session control function (P-CSCF) and a home serving-call session control function (S-CSCF) of the home network. - View Dependent Claims (10, 11, 12, 13, 14)
