1. A method for selecting a particular Third-Part Service Provider (TPSP) service from a plurality of available TPSP services covering similar or the same business objective and being offered by one or more of TPSPs to a service provider (SP) via an electronic network, said method comprising the steps of:

a) calling a Meta Service Selector (MSS) to select the best TPSP service according to a predetermined evaluating scheme referring to predetermined evaluation attributes and a predetermined evaluation algorithm,

b) sending an enquiring request enquiring respective request properties of a TPSP service to a TPSP, wherein the enquiring request demands the enquired service property information to be delivered formatted according to an interface data scheme agreed on between the enquiring SP request and said TPSP service,

d) evaluating the enquired information from the plurality of TPSPs according to a predetermined rating scheme; and

e) selecting a particular TPSP service for providing it via an electronic network to a service requesting client of the SP.

2. The method according to claim 1, wherein the enquiring request specifies time information, when the TPSP service selection shall be performed.

3. The method according to claim 2, wherein a flag is used for encoding the point in time, when the TPSP service has to be selected.

4. The method according to claim 3, wherein the point in time is selected from the group as follows:

a) the point in time, at which the TPSP service is offered by said SP, or,

b) the point in time, at which a client of the SP declares his willing to buy said SP service, or

c) the point in time, at which the TPSP service is invoked the first time, or

d) the point in time, at which the TPSP service is invoked.

5. The method according to claim 1, wherein the on-demand TPSP service is encapsulated via a resource instance created by a Generic Resource Manager GRM) acting as interface.

6. The method according to claim 1, wherein the interface data scheme agreed on between enquiring SP and said responding TPSP is part of the requested on-demand service.

7. A method for selecting a particular TPSP service from a plurality of available TPSP services covering similar or the same business objective and being offered by one or a respective plurality of TPSPs to a SP via an electronic network, said method comprising the steps of:

a) receiving an enquiring request enquiring respective request properties of a TPSP service to a TPSP, wherein the enquiring request demands the enquired service property information to be delivered formatted according to an interface data scheme agreed on between the enquiring SP request and said TPSP service, and

b) answering the enquired information to the enquiring SP.

8. A computer program for execution in a data processing system comprising a functional component having computer program code portions for performing respective steps of:

a) calling a Meta Service Selector (MSS) to select the best TPSP service according to a predetermined evaluating scheme referring to predetermined evaluation attributes and a predetermined evaluation algorithm,

b) sending an enquiring request enquiring respective request properties of a TPSP service to a TPSP, wherein the enquiring request demands the enquired service property information to be delivered formatted according to an interface data scheme agreed on between the enquiring SP request and said TPSP service,

c) evaluating the enquired information from said plurality of TPSPs according to a predetermined rating scheme, and

d) selecting a particular TPSP service for providing it via an electronic network to a service requesting client of the SP.

9. A computer program for execution in a data processing system comprising a functional component having computer program code portions for performing respective steps of:

a) receiving an enquiring request enquiring respective request properties of a TPSP service to a TPSP, wherein the enquiring request demands the enquired service property information to be delivered formatted according to an interface data scheme agreed on between the enquiring SP request and said TPSP service,

b) answering the enquired information to the enquiring SP, and

c) a signal bearing media bearing the program code portions.

10. A method for providing on-demand services via an electronic network from a service provider (SP) to a client requesting a service, wherein a third-party service provider (TPSP) is involved for providing one or more on-demand TPSP services as a contribution to said client-requested service, comprised of operating a service environment, which is ready to include, e.g., a plurality of handles to resources required to fulfill the service, wherein a generic interface definition is used between TPSP and SP comprising a pre-defined syntax and semantic for encapsulating said requested TPSP services into the service environment of said SP.

11. The method according to claim 10, wherein said generic interface definition allows performing the following steps:

a) requesting a handle for said TPSP service from said TPSP,

b) receiving a response to said request including a handle to a resource instance service dedicated to fulfill said TPSP service,

c) issuing an allocation order for allocating resources defined by said resource instance service,

d) using said TPSP service via an access interface associated with said allocated resources, and

e) issuing a deallocation order for said used resources.

14. The method according to claim 11 wherein said generic interface definition allows performing the steps of subscribing and unsubscribing to a resource.

15. The method according to claim 11 wherein a resource instance comprises another service.

16. The method according to claim 11 wherein said generic interface definition allows performing the steps of disclosing to the SP information concerning the availability of resources available at the TPSP.

12. A method for providing Third-Party Service Provider (TPSP) services from a TPSP via an electronic network to a Service Provider (SP) requesting a predefined TPSP service, comprised of operating a service environment, which is ready to offer a plurality of handles to resources required to fulfill said TPSP service, wherein a generic interface definition is used between said SP and said TPSP comprising a pre-defined syntax and semantic for encapsulating said requested TPSP services into the service environment of said SP.

13. The method according to claim 12, wherein said generic interface definition allows performing the following steps:

a) receiving a request for a handle for said TPSP service from said SP,

b) creating a resource instance service associated with said requested handle and a handle for said TPSP service,

c) issuing said requested handle to the requesting SP,

d) receiving an allocation order for allocating resources defined by said resource instance service,

e) allocating said ordered resource, if said resources are available for use,

f) receiving usage commands for the usage of said allocated resources via an access interface associated with said allocated resources,

g) receiving a deallocation order for said used resources, and

h) deallocating said used resources.
