Abstract

A mediation Service Control Point (SCP) capable of communicating Signaling Connection Control Part (SCCP) based signals is interfaced between a plurality of Service Control Points (SCPs) each providing IN services and a Service Switching Point (SSP) serving a particular IN subscriber. In response to a need to utilize an IN service, the serving SSP transmits a query signal to the mediation SCP. The mediation SCP determines which SCP or SCPs are associated with the indicated IN subscriber and accordingly invokes or executes the determined one or more SCPs to provide the needed IN service. As a result, a one-to-one relationship imposed on the serving telecommunications network is relaxed and an IN subscriber is able to utilize IN services by way of multiple SCPs.

Claims

1. A method for providing multiple IN services via multiple service control points (SCPS) within a telecommunications network, said method comprising the steps of:

receiving a signal at a mediation service control point (SCP) associated with said telecommunications network, said signal requesting an IN service toward a particular subscriber;

identifying a plurality of service control points (SCPs) associated with said particular subscriber which need to be accessed in order to provide the requested IN service;

determining an order of execution with respect to said identified plurality of SCPs; and

communicating with said identified plurality of SCPs in the determined order of execution to provide said requested IN service toward said particular subscriber.

2. The method of claim 1 wherein said step of communicating with said identified plurality of SCPs further includes the steps of:

receiving a signal from each of said plurality of SCPs, said signal including data parameters; and

authenticating and error-checking said received data parameters within the signal by said mediation SCP.

3. The method of claim 2 further comprising the step of communicating said authenticated signal to a service switching point (SSP) serving said subscriber.

4. The method of claim 1 wherein said step of communicating further comprises the steps of:

executing a first SCP in the determined order of execution;

receiving a signal at said mediation SCP from said first SCP, said signal including data representing routing instructions associated with said subscriber; and

executing a next SCP in the determined order of execution by communicating said received first SCP data from said mediation SCP to said next SCP.

5. The method of claim 1 wherein the determined order of execution comprises concurrently executing said identified plurality of SCPs.

6. The method of claim 1 wherein the determined order of execution comprises sequentially executing said identified plurality of SCPS.

7. A telecommunications node for associating a plurality of service control point (SCP) with a particular subscriber within a telecommunications network, said subscriber further associated with a particular service switching point (SSP), comprising:

an interface module for interfacing with said plurality of service control points (SCPs) and with said SSP;

a first register for storing data correlating said plurality of SCPs with said subscriber and for identifying an order with which the plurality of SCPs need to be executed in order to provide a requested IN service toward said particular subscriber; and

an application module for accessing said first register to identify the plurality of applicable SCPs and the order for execution in order to provide the requested IN service to said subscriber.

8. The telecommunications node of claim 7 wherein said interface module is capable of communicating Signaling Connection Control Part (SCCP) based signals.

9. The telecommunications node of claim 7 further comprises a second register for storing data to authenticate and to error-check data received from said plurality of SCPs.

10. The telecommunications node of claim 7 wherein the order of execution specifies an order that the plurality of SCPs need to be sequentially executed in order to provide the requested IN service toward said particular subscriber.

11. The telecommunications node of claim 7 wherein the order of execution specifies an order that the plurality of SCPs need to be concurrently executed in order to provide the requested IN service toward said subscriber.

12. A system for providing a telecommunications service toward a particular subscriber within a telecommunications network, comprising:

a plurality of service control points (SCPs) each providing a particular subscriber service;

a local end office for serving a particular subscriber; and

a mediation service control point for interfacing said plurality of SCPs with said local end office for providing said telecommunications service toward said particular subscriber, wherein said mediation service control point includes a register for storing data correlating a plurality of SCPs with said subscriber and an application module for accessing said register to identifying the plurality of SCPs that need to be executed in order to provide a requested IN service to said subscriber as well as an order with which the identified plurality of SCPs must be executed in providing the requested IN service to said subscriber.

13. The system of claim 12 wherein said local end office comprises a Service Switching Point (SSP) serving said subscriber.

14. The system of claim 12 wherein said mediation SCP further comprises a register for storing authentication data utilized for error-checking data received from one or more of said plurality of SCPs associated with said subscriber.

15. The system of claim 12 wherein the order with which the SCPs must be executed specifies an order that the plurality of SCPs need to be sequentially executed in order to provide the requested IN service toward said subscriber.

16. The system of claim 12 wherein the order with which the SCPs must be executed specifies an order that the plurality of SCPs need to be concurrently executed in order to provide the requested IN service toward said subscriber.
