Abstract

Claims (28)

1. A method of selectively terminating a custom application in a mobile telecommunications network, comprising:

receiving, by a Gateway Mobile Switching Center (GMSC), a request to initiate a call session to a subscriber device in a service area of a first Mobile Switching Center (MSC);

establishing, by the GMSC, a dialogue to implement the custom application on the subscriber device;

receiving, by the GMSC, a message indicating that the subscriber device is moving from the first MSC to a second MSC;

analyzing, by the GMSC, a service key of the custom application to determine whether or not the dialogue should be terminated and the custom application ceased; and

in response to determining, by the GMSC, that the dialogue should not be terminated, continuing the custom application on the subscriber device.

2. The method of claim 1 wherein the mobile telecommunications network supports Mobile Terminating Roaming Retry.

3. The method of claim 1 wherein the message indicating that the subscriber device is moving is a Resume Call Handling (RCH) message received from the first MSC.

4. The method of claim 1 wherein the service key comprises a control action configured by a service provider to indicate that the custom application should not be terminated.

5. The method of claim 4 wherein the dialogue is an application level dialogue.

6. The method of claim 4 wherein the dialogue comprises a Customized Applications for Mobile networks Enhanced Logic (CAMEL) application protocol.

7. The method of claim 1 wherein the custom application is an intelligent network (IN) customized application.

8. The method of claim 1 wherein the custom application comprises CAMEL.

9. The method of claim 1 further comprising continuously providing the custom application without interruption after the GMSC determines that the dialogue should not be terminated.

10. The method of claim 1 wherein the service key is configured, by the GMSC, based on a type of the custom application.

11. The method of claim 1 further comprising:

receiving, by the GMSC, a request to establish the dialogue; and

analyzing, by the GMSC, said service key of the custom application to determine whether or not the dialogue should be established.

12. The method of claim 1 further comprising:

establishing, by the GMSC, a plurality of dialogues to implement a plurality of custom applications on the subscriber device, each custom application having a customer application service key;

analyzing, by the GMSC, the customer application service key of a first custom application to determine whether or not a dialogue corresponding to the first custom application should be terminated and the first custom application ceased; and

determining, by the GMSC, based on a service key corresponding to a second custom application that a dialogue corresponding to the second custom application should not be terminated.

13. A computing device for use in a system which performs mobile switching, the computing device being configured to:

receive a request to initiate a call session to a subscriber device in a service area of a first Mobile Switching Center (MSC);

establish a dialogue to implement a custom application on the subscriber device;

receive a message indicating that the subscriber device is moving from a first MSC to a second MSC;

analyze a service key of the custom application to determine whether or not the dialogue should be terminated and the custom application ceased; and

in response to determining that the dialogue should not be terminated, continue the custom application on the subscriber device.
