Abstract

The method for implementing an Intelligent Content Rating middleware platform and gateway system provides telecommunications carriers and network operators with the ability to define routing and actions based on HTTP/SIP based content and subscriber context through a powerful, extensible Layer 4-7 switching fabric technology. The disclosed embodiments mediate communications between applications and networks for IP packet flows, personal messaging, location-based services, and billing. Furthermore, the disclosed embodiments enable advanced context-sensitive dialogue scenarios with the wireless subscriber such as, but not limited to, Advice-of-Charge dialogues. The disclosed embodiments permit telecommunications network operators and like entities to introduce real-time rating of data services for both prepaid and postpaid subscribers. Further embodiments include the validation of digital signatures, combined with authentication and non-repudiation techniques to ensure subscriber privacy remains protected.

Claims

1. A middleware gateway system comprising:

a carrier network for carrying traffic to and from a wireless device connected to said carrier network;

a second network for providing content in response to a content request from said wireless device;

a middleware platform configured to connect to said carrier network via a first link and configured to receive said content request from said wireless device via said first link, said first link comprising a connection between said middleware platform and an access gateway point associated with said carrier network;

said middleware platform further configured to connect to said second network via a second link and to carry traffic between said carrier network and said second network;

said middleware platform configured to maintain a record containing at least one predefined identifier and to perform a determination as to whether at least one of said content request and a response to said content request includes content that matches one or more of said predefined identifiers;

said middleware platform further configured to rate said response and to perform one or more of blocking, embellishing and re-routing said response based on results of said determination;

said middleware platform further configured to connect to a billing element via a third link discrete from said first and second links, for managing a subscriber account balance in association with said at least one of blocking, embellishing, re-routing, and rating;

said middleware platform additionally connected to a service control point via said third link for deducting a balance from a prepaid wireless account based on said rate.

2. The system of claim 1, wherein said identifiers include communication protocol headers associated with said content which are generated by and directed to said wireless device.

3. The system of claim 2, wherein such communication protocols comprise at least one of hyper-text transfer protocol (HTTP) and Session Initiation Protocol (SIP).

4. The system of claim 1, wherein said predefined identifier comprises rules loaded into logical memory of said middleware platform, said rules including at least one of a protocol, a domain name, a port, a path and a query string.

5. The system of claim 4, whereupon loading the rating rules into the middleware platform, a set of system level triggers are armed to detect the content request being received at said middleware platform and to determine whether said request includes content that matches one or more of said predefined identifiers.

6. The system of claim 5, wherein said triggers are real time triggers on the basis of characteristics of said content request;

said characteristics including at least one of (a hostname, a port, a path, a filename), and a protocol.

7. The system of claim 5, wherein said middleware platform is configured to maintain a logical decision tree based upon said rules.

8. The system of claim 7, whereby said content request is comprised of packets and each of said packets are analyzed according to said rules.

9. The system of claim 1 wherein said identifier is an Interesting Uniform Resource Identifier (URI).

10. The system of claim 1 wherein said middleware platform is further configured to perform digital rights management in relation to responses to said content request destined for said wireless device.

11. The system of claim 1 wherein said embellishment comprises said middleware platform being configured to provide an interstitial screen to said wireless subscriber device prior to permitting said response to be delivered to said wireless device.

12. The system of claim 11 wherein said interstitial screen advises a subscriber of said wireless device of a charge associated with providing said response.

13. The system of claim 1, said middleware platform additionally connected to a post paid billing server for adding a balance to a post paid wireless account based on said rate.

14. A method for implementing a middleware platform comprising:

receiving a content request from a wireless device via a carrier network at a middleware platform;

said middleware platform connected to said carrier network via a first link, said first link comprising a connection between said middleware platform and an access gateway point associated with said carrier network, said middleware platform connected to a second network via a second link;

said content request destined for said second network;

maintaining at said middleware platform a record containing at least one predefined identifier;

determining at said middleware platform whether said request includes content that matches one or more of said predefined identifiers;

performing at said middleware platform rating of said content and one or more of blocking, embellishing and re-routing said content based on results of said determining step;

managing by said middleware platform, in association with performing said rating and said one or more of blocking, embellishing and re-routing, a subscriber account balance associated with a billing element;

said middleware platform connected to said billing element via a third link discrete from said first and second links;

transmitting a request from said middleware platform for deducting a balance from a prepaid wireless account at a service control point based on said rating, said middleware platform connected to said service control point via said third link.

15. The method of claim 14, wherein said identifiers include communication protocol headers associated with said content which are generated by and directed to said wireless device.

16. The method of claim 15, wherein such communication protocols comprise at least one of hyper-text transfer protocol (HTTP) and Session Initiation Protocol (SIP).

17. The method of claim 14, wherein said predefined identifier comprises rules loaded into logical memory of said middleware platform, said rules including at least one of a protocol, a domain name, a port, a path and a query string.

18. The method of claim 17, whereupon loading the rating rules into the middleware platform, additionally arming a set of system level triggers to detect the content request being received at said middleware platform and determining whether said request includes content that matches one or more of said predefined identifiers.

19. The method of claim 18, wherein said triggers are real time triggers on the basis of characteristics of said content request;

said characteristics including at least one of a hostname, a port, a path, a filename, and a protocol.

20. The method of claim 18, further comprising maintaining at said middleware platform a logical decision tree based upon said rules.

21. The method of claim 20, whereby said content request is comprised of packets and each of said packets are analyzed according to said rules.

22. The method of claim 14 wherein said identifier is an Interesting Uniform Resource Identifier (URI).

23. The method of claim 14 further comprising performing at said middleware platform digital rights management in relation to responses to said content request destined for said wireless device.

24. The method of claim 14 wherein said embellishing comprises providing an interstitial screen from said middleware platform to said wireless subscriber device prior to permitting said response to be delivered to said wireless device.

25. The method of claim 14 wherein said interstitial screen advises a subscriber of said wireless device of a charge associated with providing said response.

26. The method of claim 14 further comprising transmitting a request for adding a balance to a post paid wireless account based on said rate.
