Abstract

Methods and apparatus, including computer program products, for multiplexing multiple mobile services on a single mobile access point name (APN). A method includes, in a General Packet Radio Service (GPRS) network, examining Internet Protocol (IP) packets that traverse a mobile GN link of a Gateway GPRS Support Node (GGSN), and applying a combination of packet protocols coupled with a carrier defined set of work flow rules to route the IP packets to their next destination and earmark billing CDRs for mediation and correlation by back office IT systems residing with a carrier in the mobile network.

Claims

1. A method comprising:

in a mobile network, receiving a flow of Internet Protocol (IP) packets having a generic access point name (APN) at a traffic steering server, the generic APN assigned by a carrier in the mobile network and representing a plurality of services;

identifying a specific service multiplexed on the generic APN, wherein identifying the specific service comprises applying deep packet inspection (DPI) to the flow of IP packets and combining the DPI with subscriber information associated with the flow of IP packets; and

routing the flow of IP packets to an application service element based on the identification.

2. The method of claim 1 wherein the plurality of services comprise general browsing, multimedia messaging, visual voice mail and open internet access.

3. The method of claim 1, wherein the subscriber information associated with the flow of IP packets resides in a carrier database residing in the network.

4. The method of claim 1 further comprising earmarking billing call detail records (CDRs) for mediation and correlation by back office IT systems residing with the carrier in the network so the service receives billing.

5. The method of claim 1 wherein the flow of IP packets represent a service request from a mobile device in the mobile network.

6. The method of claim 1 wherein the application service element comprises a server for general browsing, multimedia messaging, visual voice mail or open internet access.

7. A method comprising:

in a General Packet Radio Service (GPRS) network, examining Internet Protocol (IP) packets that traverse a mobile GN link of a Gateway GPRS Support Node (GGSN); and

applying a combination of packet protocols coupled with a carrier defined set of work flow rules to route the IP packets to their next destination and earmark billing call detail records (CDRs) for mediation and correlation by back office IT systems residing with a carrier in the mobile network, wherein applying the combination of packet protocols comprises applying deep packet inspection (DPI) to the flow of IP packets and combining the DPI with subscriber information associated with the flow of IP packets.

8. The method of claim 7 wherein the IP packets represent a service request from a GPRS mobile device.

9. The method of claim 7 wherein the service request is selected from the group consisting of general browsing, multimedia messaging, visual voice mail and open internet access.

10. The method of claim 7 wherein the carrier defined set of work flow rules comprise database dips and policy queries.

11. The method of claim 7 wherein the IP packets comprise a generic access point name (APN) assigned by a carrier in the mobile network.

12. The method of claim 7 wherein applying the DPI comprises performing packet inspection at Level 4 of the IP packets to determine a specific service being requested.

13. The method of claim 7 wherein the next destination is a specific application service element.

14. The method of claim 13 wherein the specific application service element comprises a server for general browsing, multimedia messaging, visual voice mail or open internet access.

15. A method comprising:

in a General Packet Radio Service (GPRS) network, assigning a generic access point name (APN) to a plurality of services; and

routing a flow of Internet Protocol (IP) packets having the APN to a traffic steering server for routing the flow of IP packets to an application service element based on an identification of the IP packets, the identification of the IP packets comprising an application of a combination of packet protocols, wherein the application of the combination of packet protocols comprises applying deep packet inspection (DPI) to the flow of IP packets and combining the DPI with subscriber information associated with the flow of IP packets.

16. The method of claim 15 wherein the plurality of services comprise general browsing, multimedia messaging, visual voice mail and open internet access.

17. The method of claim 15 wherein identifying the IP packets further comprises coupling the combination of packet protocols with a carrier defined set of work flow rules.

18. The method of claim 15 wherein the application service element comprises a server for general browsing, multimedia messaging, visual voice mail or open internet access.

19. The method of claim 15 further comprising earmarking billing call detail records (CDRs) for mediation and correlation by back office IT systems residing with a carrier in the mobile network.
