System and method for enabling group subscription for asynchronous push-based applications on a wireless device

1 . A system for enabling group subscription for asynchronous push-based applications on wireless devices, the system comprising:

an application registry;

an application repository; and

an application gateway server including an event sink for communicating between the system and a device, the application gateway server configured for communication with a back-end service via an event source and including a subscription collection and a subscriber collection.

2 . The system as claimed in claim 1 , wherein the event source is in the back-end service.

3 . The system as claimed in claim 1 , wherein the event sink is a proxy in the application gateway.

4 . The system as claimed in claim 1 , wherein the application registry includes an entry for a component application in the application repository.

5 . The system as claimed in claim 1 , wherein the application repository includes a component application for accessing the back-end service via the event source.

6 . The system as claimed in claim 1 , wherein the system enables notification message broadcast to multiple subscribers to data content.

7 . A method of enabling group subscription for asynchronous push-based applications on wireless devices, the method comprising:

reading a first Web service interface;

generating a second Web service interface therefrom conforming to a notification protocol;

creating a notification-based application bundle for the second Web service;

publishing the notification-based application bundle; and

creating an event source.

8 . The method as claimed in claim 7 , further comprising the steps of:

creating a subscription collection; and

creating a subscriber collection.

9 . The method as claimed in claim 8 , wherein the subscriber collection contains a plurality of (device, application) pairs.

10 . The method as claimed in claim 8 , further comprising the steps of:

receiving a first subscription request having filter content and a destination;

determining if a subscription message having the filter content and destination has been previously received; and

sending a second subscription request if the subscription message has not been previously received.

11 . The method as claimed in claim 10 , wherein the step of determining comprises the step of comparing the filter content and destination with subscription message data in the subscriber collection.

12 . The method as claimed in claim 10 , wherein the step of determining comprises the step of comparing the filter content and destination with subscription message information in the subscription collection.

13 . The method as claimed in claim 8 , further comprising the steps of:

receiving a notification having filter content and a destination from the event source;

comparing the filter content and destination with subscriber information in the subscriber collection; and

sending the notification to subscribers that have the filter content and destination.

14 . The method as claimed in claim 8 , further comprising the steps of:

receiving a notification having filter content and a destination from the event source;

comparing the filter content and destination with subscriber information in the subscription collection; and

sending the notification to subscribers that have the filter content and destination.

15 . The method as claimed in claim 7 , wherein the method is executed in a system having:

an application registry;

an application repository; and

an application gateway server including an event sink for communicating between the system and a device, the application gateway server configured for communication with a back-end service via an event source

16 . A computer-readable medium storing instructions or statements for use in the execution in a computer of a method of enabling group subscription for asynchronous push-based applications on wireless devices, the method comprising the steps of:

reading a Web service interface;

generating a Web service interface therefrom conforming to a notification protocol;

creating a notification-based application bundle for the Web service;

publishing the notification-based application bundle; and

creating an event source.

17 . A propagated signal carrier carrying signals containing computer-executable instructions that can be read and executed by a computer, the computer-executable instructions being used to execute a method of enabling group subscription for asynchronous push-based applications on wireless devices, the method comprising the steps of:

reading a Web service interface;

generating a Web service interface therefrom conforming to a notification protocol;

creating a notification-based application bundle for the Web service;

publishing the notification-based application bundle; and

creating an event source.
