Abstract

A web services enablement system includes a computer adapted to send and receive information to and from a first service, to send and receive information to and from a second service, which may not be a web service, to manage a connection with a third, stateful, service and to send and receive information via the stateful service based on information received from the first service or the second service. Also a method of enabling two-way web services and stateful transactions that includes steps of providing an architecture of base services and meta-services, defining a first base service comprising a core component and an extension component, combining the first base service and a meta-service to create a first usable service, managing a relationship between the first usable service and a second service through dependency or binding or utility, and performing a stateful transaction using the first usable service.

Claims

1. A web services enablement system for two-way web services and stateful transactions comprising:

a computer adapted to send and receive information to and from a first service, to send and receive information to and from a second service, to manage a connection with a third service comprising a stateful telecommunication service and to send and receive information via the stateful telecommunication service based on information received from the first service or the second service, wherein said computer enables a user to define available services in terms of meta-services and base services and wherein said base services provide specific functions of a particular domain and said meta-services enforce rules for certain common aspects of the base services.

2. The web services enablement system of claim 1 wherein said meta-services are independent of said base services and can be combined with different ones of said base services to define different usable services.

3. The web services enablement system of claim 1 wherein the available services are related through the structure of dependency, binding and utility.

4. The web services enablement system of claim 1 wherein said base services comprise a service core and a service extension, said service core being protected and said service extension being changeable.

5. The web services enablement system of claim 1 wherein said stateful telecommunication service is managed by making the processing of service messages stateless and making the resources used in the processing of service messages stateful.

6. The web services enablement system of claim 1 including a topic tree abstracting resources from multiple available services into a topic hierarchy having event propagation rules.

7. The web services enablement system of claim 1 wherein said computer:

performs enablement of available services by an architecture of base services and meta-services abstraction and interaction;

enables available services with a mechanism and a two-dimensional hierarchy of core/extension and stateless/stateful;

manages relationships between available services through dependency, binding and utility; and

utilizes a topic tree sharing architecture to abstract resources.

8. The web services enablement system of claim 1, wherein said third service comprises a session-based service.

9. The web services enablement system of claim 1, wherein the stateful telecommunication service comprises a telephone call to a telecommunications device.

10. A web services enablement system for two-way web services and stateful transactions comprising:

a non-transitory computer readable recording medium containing instructions for causing a computer to send and receive information to and from a first service, to send and receive information to and from a second service, to manage a connection with a stateful telecommunication service and to send and receive information via the stateful telecommunication service based on information received from the first service or the second service, wherein said instructions enable a user to define available services in terms of meta-services and base services and wherein said base services provide specific functions of a particular domain and said meta-services enforce rules for certain common aspects of the base services.

11. The web services enablement system of claim 10 wherein said meta-services are independent of said base services and can be combined with different ones of said base services to define different usable services.

12. The web services enablement system of claim 10 wherein the available services are related through the structure of dependency, binding and utility.

13. The web services enablement system of claim 10 wherein said base services comprise a service core and a service extension, said service core being protected and said service extension being changeable.

14. The web services enablement system of claim 10 wherein said instructions enable the stateful telecommunication service to be managed by making the processing of service messages stateless and making the resources used in the processing of service messages stateful.

15. The web services enablement system of claim 10 wherein said instructions cause a computer to define a topic tree abstracting resources from multiple available services into a topic hierarchy having event propagation rules.

16. The web services enablement system of claim 10 wherein said computer readable medium includes instructions for causing a computer to:

perform enablement of available services by an architecture of base services and meta-services abstraction and interaction;

enable base services with a mechanism and two-dimensional hierarchy of core/extension and stateless/stateful;

manage relationships between available services through dependency, binding and utility; and

utilize a topic tree sharing architecture to abstract resources.

17. The web services enablement system of claim 10, wherein said stateful telecommunication service comprises a session-based service.

18. The web services enablement system of claim 10, wherein the stateful telecommunication service comprises a telephone call to a telecommunications device.

19. A method of enabling two-way web services and stateful telecommunication transactions comprising the steps of:

defining a first base service comprising a core component and an extension component;

combining the first base service and a meta-service to create a first usable service;

managing a relationship between the first usable service and a second service through dependency or binding or utility;

performing a stateful telecommunication transaction using the first usable service, and

including the additional step of providing a topic tree sharing architecture abstracting resources from various available services into a uniform topic hierarchy having event propagation rules.

20. The method of claim 19, wherein said stateful telecommunication transaction comprise establishing a telecommunication session among at least two clients.

21. The method of claim 19, wherein performing a stateful telecommunication transaction comprises placing a telephone call.
