Abstract

A method and apparatus are provided for the secure delivery of converged services to users of wireless devices in a wireless environment. An application layer broker is position between the user devices and the application server to provide an indirect coupling between the enterprise application server and the wireless user devices. The application layer broker links the wireless environment to the enterprise application server through an event triggered content delivery mechanism without providing a direct link between the wireless user device and the enterprise application server. Delivered content can only be accessed by the intended user and the authorized device. The application layer broker provides adaptation to various user devices and the various capabilities associated with each user device. Wireless devices can be upgraded independently from upgrades to the application server. The decoupling performed by the application layer broker separates the service control, such as user registration from the service delivery.

Claims

1. A wireless communication system, comprising:

one or more wireless communication devices;

at least one application server for delivering content to said one or more wireless communication devices; and

an application layer broker between said one or more wireless communication devices and said at least one application server, wherein said application layer broker provides an indirect coupling between said at least one application server and said one or more wireless communication devices; and

an event-triggered content delivery mechanism, wherein said event-triggered content delivery mechanism receives requests to transfer said content, transfers said content from said application server to said application layer broker, and generates an event notification to at least one of said wireless communication devices, wherein said event notification provides said indirect coupling and includes linkage information to allow said at least one of said wireless communication devices to access said content from said application layer broker.

2. The wireless communication system of claim 1, wherein said at least one application server is protected by a firewall and said one or more wireless communication devices are outside of said firewall.

3. The wireless communication system of claim 1, wherein communications between said application server and said application layer broker are initiated only by said application server.

4. The wireless communication system of claim 1, wherein said application layer broker links said one or more wireless communication devices to said application server through said event triggered content delivery mechanism.

5. The wireless communication system of claim 4, wherein said event triggered content delivery mechanism allows said application layer broker to provide separate channels for a registration of said wireless communication device and a delivery of said content to said wireless communication device.

6. The wireless communication system of claim 4, wherein said event triggered content delivery mechanism temporarily stores collected device intimation in a queue to be obtained by said application server.

7. The wireless communication system of claim 6, wherein said application server performs a query to obtain said collected device information.

8. The wireless communication system of claim 1, wherein said application layer broker provides adaptation to a plurality of said wireless communication devices.

9. The wireless communication system of claim 8, wherein said adaptation to a plurality of said wireless communication devices is performed by dynamically binding a device capability query with a generation and presentation of said content.

10. A wireless communication system for providing content from an application server to a wireless communication device, comprising:

an application layer broker between said wireless communication device and said application server, wherein said application layer broker provides separate channels for a registration of said wireless communication device and a delivery of said content to said wireless communication device; and

an event-triggered content delivery mechanism, wherein said event-triggered content delivery mechanism receives requests to transfer said content, transfers said content from said application server to said application layer broker, and generates an event notification to said wireless communication device, wherein said event notification provides said indirect coupling and includes linkage information to allow said wireless communication device to access said content from said application layer broker.

11. The wireless communication system of claim 10, wherein said application layer broker links said one or more wireless communication devices to said application server through said event triggered content delivery mechanism.

12. The wireless communication system of claim 11, wherein said event triggered content delivery mechanism allows said application layer broker to provide separate channels for a registration of said wireless communication device and a delivery of said content to said wireless communication device.

13. The wireless communication system of claim 11, wherein said event triggered content delivery mechanism temporarily stoics collected device information in a queue to be obtained by said application server.

14. The wireless communication system of claim 13, wherein said application server performs a query to obtain said collected device information.

15. The wireless communication system of claim 10, wherein said at least one application server is protected by a firewall and said one or more wireless communication devices are outside of said firewall.

16. A method performed by an application layer broker for delivering content to a wireless device from an application server, comprising:

receiving a request from a user associated with said wireless device for said content;

providing said request to said application server, wherein said request is event triggered;

receiving said content from said application server;

encoding said content with authentication information so that said content may only be accessed by said wireless device;

generating an event notification to said wireless device, wherein said event notification provides said indirect coupling and includes linkage information to allow said wireless device to access said content from said application layer broker; and

providing said encoded content for access by said wireless device.

17. The method of claim 16, wherein said application server pushes a service to said application layer broker through a secure service delivery mechanism.

18. The method of claims 16, further comprising the step of temporarily placing said content in a queue for delivery to said wireless device, wherein said content is fetched from said queue for delivery to said wireless device.

19. The method of claim 16, wherein said application layer broker provides adaptation to a plurality of wireless communication devices.

20. The method of claim 19, wherein said adaptation to a plurality of said wireless communication devices is performed by dynamically binding a device capability query with a generation and presentation of said content.
