Definitions
- WIPO Patent Application (WO) 03067830 by Camunas et al. entitled a system to obtain value- added services in real-time, based on the General Packet Radio Service (GPRS) network, discloses a system to obtain value-added services in real-time based on the General Packet Radio Service (GPRS) network, which comprises SGSN and GGSN nodes to enable the access from a mobile station to different data networks, using the radio access of a GSM or UMTS network; wherein between the SGSN and GGSN nodes the invention comprises means to handle GTP protocol data packets, and wherein the GTP messages traffic, which would have otherwise flowed directly between the SGSN and the GGSN nodes, is diverted through said means.
- GPRS General Packet Radio Service
- said means When said means detect a GTP message from an SGSN asking a GGSN for the establishment of a GTP tunnel for a PDP context, said means establish instead two GTP tunnels: one between the Camunas et al.'s invention and the SGSN and the other between Camunas et al.'s invention and the GGSN (once established, the user data packets will arrive through one of the two tunnels associated to their PDP Context and will be transferred to the other tunnel).
- Camunas et al.'s invention requires all GTP packets to be intercepted, whereas the invention disclosed herewith only requires and speaks to the intermediation of GTP-C (the control) packets which remains a more resourceful approach to advancing the practice of the art.
- our invention may monitor the GTP-U packets or alternatively rely on the packet intermediations of the method for implementing an Internet Protocol (IP) charging and rating middleware platform and gateway system as detailed in Patent Application 10/348972, for the purpose of providing the data intermediation and intercept functionality on the data plane.
- IP Internet Protocol
- the present invention relates generally to wireless telecommunications and gateway/intercept services; and more specifically, to a method for the interception of GTP messages.
- control-message intercept method which includes a passive monitoring approach whereby the relevant control packets are inspected for the purpose of providing additional information for the further additional purpose of facilitating the operation of some primary or 'master' Internet Protocol (IP) charging/rating middleware platform / gateway system (intended to equip network operators with the ability to rate and bill IP traffic), and secondly, an invasive technique whereby control (GTP-C) messages are injected for the purpose of altering the state of a given data session in an more aggressive fashion (e.g. to drop a data session when the subscriber runs out of money in his/her prepaid account).
- IP Internet Protocol
- GTP-C control
- FIG. 1 illustrates a typical, non-limiting embodiment of the system level architecture employed in the disclosure of present.
- the method for the interception of GTP messages disclosed herewith is implemented as part of a computer program product, hereinafter, the GTP-C Control Module.
- FIG. 1 represents the preferred illustrative embodiment of the invention's architecture and, as such, depicts a fault redundant GTP-C Control Module pair 3OA 3OB surrounded by Load Balancers on either side of the pair 2OA 2OB (one pair 2OA on the SGSN side 10, the other pair 2OB on the GGSN side 50).
- the method for the interception of GTP messages may also be co-articulated and implemented with the method for implementing an Internet Protocol (IP) charging and rating middleware platform and gateway system as detailed in Patent Application 10/348972, to enhance the packet/data rating and classification mechanisms inherent in the invention disclosed hereto.
- IP Internet Protocol
- Technicians skilled in the art will recognize that the invention of present need not be limited to the aforementioned method for implementing an Internet Protocol (IP) charging and rating middleware platform and gateway system and other similar network implementations may be employed without diluting the intent and scope as such.
- the method for implementing an Internet Protocol (EP) charging and rating middleware platform and gateway system 40A 4OB will initiate the delete request to the invention (GTP-C CM) 30A 30B.
- the invention (GTP-C CM) 3OA 3OB will in turn send delete requests to both the GGSN 50 and SGSN 10 using spoofed packets.
- said deletePDPContext message can also initiate by the SGSN 10 or GGSN 50 where the invention 30A 30B intercepts the message, and further triggers the session deletion to IP charging and rating middleware platform and gateway system 4OA 4OB.
- the deletePDPContext may then be simply forwarded by the invention (GTP-C CM) 30A 30B to the GGSN 50 or SGSN 10 depending on the initiator of the deletePDPContext message.
