Abstract

A method for communicating in a wireless application protocol (WAP) network environment is provided that includes receiving a request packet at a WAP gateway and positioning an identifier into the request packet. A content switch then identifies the identifier and correlates the identifier to a source that generated the request packet. An internet protocol (IP) address associated with the source is positioned in the request packet before communicating the request packet to a next destination.

Claims

1. A method comprising:

enlisting one or more end users in a billing plan associated with wireless application protocol (WAP) network communications;

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

facilitating, by a content switch, the network communications for the at least one end user in response to the one or more end users being enlisted in the billing plan, whereby the network communications includes a protocol that comprises;

receiving, by the content switch, a request packet for network communications generated by a gateway on behalf of a mobile station operating as a source that initiated the request packet, the request packet comprising an identifier identifying the mobile station and a source address identifying the gateway; and

replacing, by the content switch, the source address of the request packet with an internet protocol (IP) address, the IP address identifying the mobile station.

2. The method of claim 1, further comprising providing a table that includes one or more identifiers that correlate to one or more sources respectively, a source being operable to generate one or more request packets for the network communications.

3. The method of claim 1, further comprising:

matching the IP address with one or more source profiles in order to provide one or more networking services to the source that initiated the request packet.

4. The method of claim 3, wherein the matching is performed by accessing and querying a database.

5. The method of claim 3, wherein the matching is performed by inspecting one or more RADIUS packets associated with the source that initiated the request packet.

6. The method of claim 3, further comprising authenticating the source that initiated the request packet.

7. The method of claim 6, further comprising authorizing the source that initiated the request packet.

8. The method of claim 6, further comprising providing a plurality of accounting services for the source that initiated the request packet, the accounting services comprising the generating the bill.

9. The method of claim 1, further comprising providing a communications link between a radio access network (RAN) packet gateway and the mobile station.

10. An apparatus for communicating in a wireless application protocol (WAP) network environment, comprising:

a content switch associated with a gateway and operable to;

receive a request packet for WAP network communications generated by the gateway on behalf of a mobile station operating as a source that initiated the request packet, the request packet comprising an identifier identifying the mobile station and a source address identifying the gateway;

replace the source address of the request packet with an internet protocol (IP) address, the IP address identifying the mobile station.

11. The apparatus of claim 10, wherein the gateway comprises the content switch, and wherein the content switch comprises a table that includes one or more identifiers that correlate to one or more sources respectively, a source being operable to generate one or more request packets in the WAP network environment.

12. The apparatus of claim 10, further comprising:

a client service packet gateway (CSPG) operable to receive the request packet from the content switch and to match one or more IP addresses with one or more source profiles in order to provide one or more networking services to the source that initiated the request packet.

13. The apparatus of claim 12, wherein the CSPG and the content switch are included in the gateway.

14. The apparatus of claim 12, wherein the matching is performed by accessing and querying a database.

15. The apparatus of claim 12, wherein the matching is performed by inspecting one or more RADIUS packets associated with a selected one or more sources.

16. The apparatus of claim 10, further comprising:

a radio access network (RAN) packet gateway operable to provide a communications link between the RAN packet gateway and the mobile station.

17. The apparatus of claim 10, further comprising:

a database coupled to the content switch and operable to store a table that includes one or more identifiers that correlate to one or more sources respectively, a source being operable to generate one or more request packets in the WAP network environment.
