Abstract

A method for detecting and directing traffic in a network environment is provided that includes receiving a packet included within a communication flow that is initiated by a mobile terminal and setting a flag within the packet. The method further includes directing the packet to a next destination by recognizing that the flag included within the packet was set and therefore is associated with a mobile-to-mobile communication session.

Claims

1. An apparatus for detecting and directing traffic in a network environment, comprising:

a gateway general packet radio service (GPRS) support node (GGSN) operable to receive a packet, included within a communication flow, that is communicated by a mobile terminal, the GGSN communicating with first and second access point name (APN) elements, wherein the first APN is operable to insert a flag into the packet from the communication flow to signify the packet is associated with a mobile-to-mobile communication session.

2. The apparatus of claim 1, wherein the second APN element is operable to direct the packet to a next destination by recognizing that the flag included within the packet was set and therefore is associated with a mobile-to-mobile communication session.

3. The apparatus of claim 1, wherein the GGSN further comprises a routing table that is coupled to the first and second APN elements and that is operable to facilitate directing of one or more packets included within the communication flow based on an address included within one or more of the packets.

4. The apparatus of claim 3, wherein the routing table directs the packet to a firewall in cases where the communication flow is associated with an Internet destination.

5. The apparatus of claim 1 wherein the first APN element sets the flag in order to indicate that the packet was sourced by the first APN element, the second APN element using the flag to identify the communication flow is associated with the mobile-to-mobile communication session.

6. The apparatus of claim 1, wherein the second APN element provides a next hop destination for the packet in cases where the communication flow is associated with the mobile-to-mobile communication session.

7. The apparatus of claim 1, wherein a firewall can receive the packet and direct the packet to the second APN, which would not set the flag, and then the packet would propagate to the mobile terminal.

8. A method for enlisting one or more end users in a network environment in which traffic direction occurs, comprising:

enlisting one or more end users in a billing plan associated with network communications;

generating a bill associated with one or more of the end users, the bill being based on the billing plan; and

facilitating network communications for one or more of the end users in response to the end users being enlisted in the billing plan, whereby the network communications includes a protocol that comprises;

receiving a packet included within a communication flow that is initiated by a mobile terminal;

setting a flag within the packet; and

directing the packet to a next destination by recognizing that the flag included within the packet was set and therefore is associated with a mobile-to-mobile communication session.

9. The method of claim 8, wherein a first APN element sets the flag in order to indicate that the packet was sourced by a first APN element, and wherein a second APN element uses the flag to identify the communication flow is associated with the mobile-to-mobile communication session.

10. The method of claim 8, further comprising:

directing one or more packets included within the communication flow based on an address included within one or more of the packets.

11. The method of claim 8, wherein a routing table directs the packet to a firewall in cases where the communication flow is associated with an Internet destination.

12. The method of claim 8, wherein the mobile terminal communicates a request to a serving GPRS support node (SGSN) in order to establish the communication flow.

13. The method of claim 8, further comprising:

providing a next hop destination for the packet in cases where the communication flow is associated with the mobile-to-mobile communication session.

14. The method of claim 8, wherein a firewall can receive the packet and direct the packet to an APN, which would not set the flag, and then the packet would propagate to the mobile terminal.

15. The method of claim 8, further comprising:

allocating bandwidth to one or more of the end users based on the billing plan.

16. The method of claim 8, wherein a first APN is operable to insert the flag into the packet from the communication flow to signify the packet is associated with a mobile-to-mobile communication session.

17. The method of claim 8, wherein an APN can configure a next hop destination for subsequent packets associated with the communication flow.

18. The method of claim 8, wherein a firewall receives the packet from an APN and confirms that the packet includes a valid mobile address.

19. The method of claim 8, wherein either a first or a second APN is involved in directing the packet, but not both.

20. The method of claim 8, wherein a first and second APN are provided within the GGSN and the GGSN communicates with an IP network.
