Abstract

A Short Message Service (SMS) communication network is interfaced with an Intelligent Network. In response to an indication from a mobile subscriber to transmit unstructured data towards a particular B-number, a serving mobile switching center/visitor location register (MSC/VLR) determines whether the calling party subscriber or called party subscriber is associated with an IN service. In response to an affirmative determination, instead of transmitting the received unstructured data directly to a Short Message Service-Center (SMS-C), the serving MSC/VLR routes an Integrated Service Digital Network User Part (ISUP) signal encapsulating the unstructured data to the associated Intelligent Network. An associated Service Switching Point (SCP) and Service Control Point (SSP) then provide the desired IN service to the received unstructured data.

Claims

1. A method for integrating components of an Intelligent Network and components of a Short Message Service (SMS) Network within a mobile telecommunications network, said method comprising the steps of:

receiving at a first telecommunications node associated with said mobile telecommunications network an indication from a calling mobile subscriber to transmit SMS data towards a called mobile subscriber;

determining whether said calling mobile subscriber or said called mobile subscriber subscribes to a service provided by the Intelligent Network; and

in response to an affirmative determination,

identifying a second telecommunications node associated with said Intelligent Network; and

transmitting said SMS data from said first telecommunications node to said second telecommunications node;

treating said transmitted SMS data in accordance with the service provided by the Intelligent Network where said calling mobile subscriber is able to communicate the SMS data while utilizing the service provided by the Intelligent Network;

forwarding said treated SMS data from said second telecommunications network to a third telecommunications network associated with said SMS Network; and

transmitting said forwarded SMS data from said third telecommunications node to said called mobile subscriber.

2. The method of claim 1 wherein said first telecommunications node comprises a mobile switching center (MSC).

3. The method of claim 1 wherein said second telecommunications node comprises a Service Switching Point (SSP).

4. The method of claim 1 wherein said third telecommunications node comprises a Short Message Service-Center (SMS-C).

5. The method of claim 1 wherein said step of determining whether said called mobile subscriber subscribes to a service provided by the Intelligent Network further includes evaluating a syntax of a dialed B-number.

6. The method of claim 1 wherein said step of transmitting said SMS data from said first telecommunications node to said second telecommunications nodes further includes transporting said SMS data using an Integrated Service Digital Network User Part (ISUP) signal.

7. The method of claim 1 wherein said service provided by the Intelligent Network further includes a selected one of a Private Number Plan (PNP), Originating Call Barring feature, Closed User Groups feature, Restriction Override feature and Call Diversion feature.

8. The method of claim 1 wherein said step of treating said transmitted SMS data further includes querying a Service Control Point (SCP) of the Intelligent Network.

9. The method of claim 1 wherein said transmitting said forwarded SMS data from said third telecommunications node to said called mobile subscriber further includes determining whether said called mobile subscriber is currently roaming.

10. A mobile telecommunications network for integrating components of an Intelligent Network with components of a Short Message Service (SMS) Network, said mobile telecommunications network comprising:

a first telecommunications node associated with said mobile telecommunications network for receiving an indication from a calling mobile subscriber to transmit SMS data towards a called mobile subscriber, said first telecommunications node further includes;

means for determining whether said calling mobile subscriber or said called mobile subscriber subscribes to a service provided by the Intelligent Network;

means, responsive to an affirmative determination, for identifying a second telecommunications node associated with said Intelligent Network; and

means for transmitting said SMS data from said first telecommunications node to said second telecommunications node;

a third telecommunications node associated with said Intelligent Network for treating SMS data received from the second telecommunications node in accordance with the service provided by the Intelligent Network, where said calling mobile subscriber is able to communicate the SMS data while utilizing the service provided by the Intelligent Network; and

a fourth telecommunications node associated with said SMS Network for transmitting the treated SMS data received from said third telecommunications node to said called mobile subscriber.

11. The mobile telecommunications network of claim 10 wherein said first telecommunications node comprises a mobile switching center (MSC).

12. The mobile telecommunications network of claim 10 wherein said second telecommunications node comprises a Service Switching Point (SSP).

13. The mobile telecommunications network of claim 10 wherein said third telecommunications node comprises a Service Control Point (SCP).

14. The mobile telecommunications network of claim 10 wherein said fourth telecommunications node comprises a Short Message Service-Center (SMS-C).

15. The mobile telecommunications network of claim 10 wherein said means for determining whether said called mobile subscriber subscribes to a service provided by the Intelligent Network further includes means for evaluating a syntax of a dialed B-number.

16. The mobile telecommunications network of claim 10 wherein said means for transmitting said SMS data from said first telecommunications node to said second telecommunications nodes further includes means for transporting said SMS data using an Integrated Service Digital Network User Part (ISUP) signal.

17. The mobile telecommunications network of claims 10 wherein said service provided by the Intelligent Network further includes a selected one of a Private Number Plan (PNP), Originating Call Barring feature, Closed User Groups feature, Restriction Override feature and Call Diversion feature.
