Abstract

A system and method that map services that are available on the internet to services that can be used by home network devices. Similar services are accessed by a single interface. A “light-weight” plugin mechanism is provided which enables the addition of new functionalities and services. As such, the system can be implemented in a gateway device in the network. Addition of new services can be achieved during run-time, without the need for compilation. Plugins are dynamically obtained via Web-based service providers when needed, whereby it is ensured that the user will use the version of plugins desired by Web-based service providers.

Claims

1. A system for making services of an external network available to a local network, comprising:

a service provider API module in the local network that allows interaction with services provided by service providers in the external network;

a client API module in the local network that interfaces client programs in the local network to service provider API module; and

a service translator module in the local network that translates client API module function calls into the service provider API module, and routes information returned in response to the call.

2. The system of claim 1 wherein the client API module comprises a collection of APIs and corresponding methods.

3. The system of claim 1 wherein the service provider API module comprises a collection of APIs and corresponding methods.

4. The system of claim 3 wherein each service provider API corresponds to a single service provider.

5. The system of claim 4 wherein each service provider API allows interaction with the services provided by the corresponding service provider.

6. The system of claim 1 wherein the service provider API module, the client API module and the service translator module, are implemented in gateway device in the local network.

7. The system of claim 1 wherein:

the client API module comprises a collection of APIs and corresponding methods;

the service provider API module comprises a collection of APIs and corresponding methods provided by the service providers;

the service translator module translates by mapping each method in the client API module to one or more methods in the service provider API module.

8. The system of claim 7 wherein the service translator module translates using scripts that map each method in the client API module to one or more methods in the service provider API module.

9. The system of claim 8 wherein the service translator module includes a script engine that provides an environment for executing plugins which are coded as scripts.

10. The system of claim 1 further comprising a profile manager that manages and supplies user information, such that the service translator module further interacts with the profile manager to provide user information required by a service provider.

11. The system of claim 1 further comprising a plugin manager that manages a collection of APIs in the service provider API module.

12. The system of claim 11 wherein the plugin manager further adds new service APIs to the service provider module for new service providers.

13. The system of claim 1 further comprising a plugin manager that manages a collection of APIs in the client API module.

14. A method for making services of an external network available to a local network, comprising the steps of:

mapping services that are available on the external network to services for use by a client application in the local network.

15. The method of claim 14 wherein the steps of mapping services further include the steps of:

translating client application requests for service into requests to services provided by service providers in the external network, thereby enabling client applications to interact with services provided by service providers in the external network.

16. The method of claim 14 wherein the steps of mapping services further include the steps of:

providing a service provider interface in the local network that interfaces with service providers in the external network;

providing a client application interface in the local network that interfaces with the client applications; and

providing a service translator in the local network that translates client application service function calls to the client application interface, into function calls in the service provider interface, thereby enabling client applications to interact with services provided by service providers in the external network.

17. The method of claim 16 further including the steps of each service provider providing a service provider API corresponds to that service provider.

18. The method of claim 17 wherein each service provider API allows interaction with the services provided by the corresponding service provider.

19. The method of claim 16 wherein the service provider interface, the client application interface and the service translator, are implemented in gateway device in the local network.

20. The method of claim 16 further including the steps of the service translator translating by mapping each method in the client application interface to one or more methods in the service provider interface.

21. The method of claim 16 further including the steps of:

maintaining user information; and

providing the user information as required by a service provider.

22. The method of claim 16 further comprising the steps of managing a collection of APIs in the service provider interface.

23. The method of claim 22 further comprising the steps of adding new service APIs to the service provider interface for new service providers.

24. The method of claim 16 further comprising the steps of managing a collection of APIs in the client application interface.

25. The method of claim 24 further comprising the steps of adding new API to the client application interface for new services.

26. The method of claim 14 further comprising the steps of:

enabling similar services to be accessed by a single interface in the local network.
