Abstract

The invention concerns a method for communicating between a service switching exchange of a telecommunication network, to which service calls requesting the execution of a service for a subscriber of the telecommunication network are routed, and a service control facility, which controls the execution of the requested service. The service switching exchange interacts with one or several objects of the service control facility via an transaction capability application part protocol. Each such object interacts and communicates via an object infrastructure with other objects in an object oriented computing environment within the service control facility. The interface of each such object maps the primitives of the transaction capability application part protocol onto the internal interface description of the each such object.

Claims

1. A method for communicating between a service switching exchange of a telecommunication network, to which service calls requesting the execution of a service for a subscriber of the telecommunication network are routed, and a service control facility, which controls the execution of the requested service, comprising the steps of:

providing data from a service switching exchange to at least one object of the service control facility and vice versa, via a transaction capability application part protocol;

providing data from said at least one object to other objects in an object oriented computing environment within the service control facility, and vice versa, via an object infrastructure; and

mapping primitives of the transaction capability application part protocol onto an internal interface description of said at least one object, using an interface of said at least one object, said internal interface description using IDL language.

2. A method as claimed in claim 1, characterized in that the TCAP protocol is used as the transaction capability application part protocol which is used in a communication according to the Intelligent Network architecture to establish a dialog between two remote processes.

3. A method as claimed in claim 1, characterized in that said at least one object interacts and communicates as a CORBA object via a CORBA object infrastructure.

4. A method as claimed in claim 1, characterized in that parameters of the primitive of the transaction capability application part protocol are converted into types of the internal interface description.

5. A method as claimed in claim 1, characterized in that INAP methods are converted into IDL types.

6. A method as claimed in claim 1, characterized in that all functions for controlling the execution of the service are implemented by a dedicated CORBA service server.

7. A method as claimed in claim 1, characterized in that the service session object has an interface definition given by TCAP mapped over IDL.

8. A method as claimed in claim 1, wherein TCAP primitives are mapped into IDL invocations invoking an internal IDL interface of said at least one object, in order to map primitives of the transaction capability application part protocol onto an interface description of said at least one object.

9. A method as claimed in claim 1, wherein every TCAP primitive is translated into an IDL method, in order to map primitives of the transaction capability application part protocol onto an interface description of said at least one object.

10. A service control facility for connecting to one or several service switching exchanges of a telecommunication network, where the service control facility comprises:

means for receiving service requests that request the execution of a service for a user of the telecommunication network from at least one of the service switching exchanges of the telecommunication network; and

at least one object interacting and communicating via an object infrastructure with other objects in an object oriented computing environment within the service control facility wherein;

said at least one object contains means for interacting with the at least one service switching exchange via a transaction capability application part protocol,

said at least one object contains an interface that maps primitives of the transaction capability application part protocol onto an internal interface description of said at least one object, and

said internal interface description uses IDL language.
