Abstract

The foregoing roaming scenarios are summarized in the Table given below. In accordance with the teachings of the present invention, a method and apparatus is presented for distinguishing between priority services. A new parameter is defined in an update location message. The new parameter enables an MSC/VLR to recognize and distinguish priority services. For example, the new parameter is used to distinguish eMLPP priority service from WPS priority service. In addition, the HLR will send a new parameter in the ISD message to distinguish which priority service subscription is applicable.

Claims

1. A method of operating comprising the steps of:

receiving a code; and

distinguishing different telecommunication services in response to receiving the code.

2. A method of operating as set forth in claim 1, wherein the code is a supplementary code.

3. A method of operating as set forth in claim 1 wherein the telecommunication services are priority services.

4. A method of operating a switch as set forth in claim 3, wherein at least one of the priority services includes a priority services capability parameter.

5. A method of operating as switch as set forth in claim 3, wherein at least one of the priority services is an eMLPP service.

6. A method of operating as switch as set forth in claim 3, wherein at least one of the priority services is a WPS service.

7. A method of operating as switch as set forth in claim 3, wherein at least one of the priority services is a hybrid service.

8. A method of operating comprising the steps of:

generating a UL message including a priority services designation;

receiving an ISD message in response to generating the UL message;

generating an ISD-ack message in response to receiving the ISD message; and

receiving a UL-ack message in response to generating the ISD-ack message.

9. A method of operating as set forth in claim 8, the UL message including eMLPP information.

10. A method of operating as set forth in claim 8, the UL message including WPS information.

11. A method of operating as set forth in claim 8, the UL message including hybrid service information.

12. A method of operating as set forth in claim 8, the ISD message including eMLPP information.

13. A method of operating as set forth in claim 8, the ISD message including WPS information.

14. A method of operating as set forth in claim 8, the ISD message including hybrid service information.

15. A method of operating comprising the steps of:

receiving a UL message including a priority services designation;

generating an ISD message in response to receiving the UL message;

receiving an ISD-ack message in response to generating the ISD message; and

generating a UL-ack message in response to receiving the ISD-ack message.

16. A method of operating as set forth in claim 15, the UL message including eMLPP information.

17. A method of operating as set forth in claim 15, the UL message including WPS information.

18. A method of operating as set forth in claim 15, the UL message including hybrid service information.

19. A method of operating as set forth in claim 15, the ISD message including eMLPP information.

20. A method of operating as set forth in claim 15, the ISD message including WPS information.
