Abstract

A method (200) for determining capability of a serving system for anchoring a call using an intelligent network protocol is provided. A communication network (100) includes a plurality of serving systems. Each serving system of the plurality of serving systems is associated with a unique identifier (ID). The method at a communication device (124) includes detecting (204) a movement of the communication device from a first serving system (102) to a second serving system (104) based on the unique ID of the first serving system and the unique ID of the second serving system. Further, the method includes accessing (206) a list that includes a mapping of the unique ID of each serving system with the intelligent network protocol capability of the serving system. Furthermore, the method includes determining (208), based on the list, whether the second serving system supports the intelligent network protocol for anchoring a call.

Claims

1. A method for determining a capability of a serving system for anchoring a call at an application server using an intelligent network protocol, wherein the communication network comprises a plurality of serving systems and wherein each serving system of the plurality of serving systems is associated with a unique identifier (ID), the method at a communication device comprising:

detecting a movement of the communication device from a first serving system of the plurality of serving systems to a second serving system of the plurality of serving systems based on the unique ID associated with the first serving system and the unique ID associated with the second serving system;

accessing a list stored at the communication device, wherein the list comprises a mapping of the unique ID associated with each serving system of the plurality of serving systems with the capability of the serving system for anchoring the call using the intelligent network protocol; and

based on the list, determining whether the second serving system supports anchoring the call using the intelligent network protocol.

2. The method as recited in claim 1, wherein the intelligent network protocol is one of a Wireless Intelligent Network (WIN) protocol and a Customized Application for Mobile network Enhanced Logic (CAMEL) protocol.

3. The method as recited in claim 1, wherein determining comprises determining that the second serving system supports the intelligent network protocol to anchor the call and wherein the method further comprises directing the second serving system to use the intelligent network protocol for anchoring the call.

4. The method as recited in claim 1 further comprising initiating a transfer of an intelligent network protocol trigger message from the second serving system to the application server.

5. The method as recited in claim 4 further comprising:

receiving a response from the application server based on the transfer of the intelligent network protocol trigger message from the second serving system to the application server; and

populating the list stored at the communication device with information related to a capability of the second serving system to anchor a call using the intelligent network protocol based on the response received from the application server.

6. The method as recited in claim 1 further comprising populating the list stored at the communication device with information related to a capability of the second serving system to anchor a call using the intelligent network protocol based on a dummy call initiated by the communication device.

7. A communication device capable of operating in a communication network comprising a plurality of serving systems, wherein each serving system of the plurality of serving systems is associated with a unique identifier (ID), the communication device comprising:

a memory configured to store a list comprising a mapping of the unique ID associated with each of the plurality of serving systems with an intelligent network protocol capability for anchoring a call at an application server for each of the plurality of serving systems;

a detector configured to detect the movement of the communication device from a first serving system of the plurality of serving systems to a second serving system of the plurality of serving systems based on the unique ID associated with the first serving system and the unique ID associated with the second serving system; and

a processor configured to;

access the list stored at the memory; and

determine, based on the list, whether the second serving system supports anchoring the call using the intelligent network protocol.

8. The communication device as recited in claim 7, wherein the intelligent network protocol is one of a Wireless Intelligent Network (WIN) protocol and Customized Application for Mobile network Enhanced Logic (CAMEL) protocol.

9. The communication device as recited in claim 7, wherein the processor is further configured to direct the second serving system to use the intelligent network protocol for anchoring the call when the processor determines that the second serving system supports the intelligent network protocol to anchor the call.

10. The communication device as recited in claim 7, wherein the processor is further configured to initiate transfer of an intelligent network protocol trigger message from the second serving system to the application server.

11. The communication device as recited in claim 10 further comprising a receiver configured to receive a response from the application server based on the transfer of the intelligent network protocol trigger message from the second serving system to the application server and wherein the processor is further configured to populate the list stored at the memory with information related to a capability of the second serving system to anchor a call using the intelligent network protocol based on the response received from the application server.

12. The communication device as recited in claim 7, wherein the processor is further configured to populate the list stored at the memory with information related to a capability of the second serving system to anchor a call using the intelligent network protocol based on a dummy call initiated by the communication device.

13. The communication device as recited in claim 7, wherein the list stored at the communication device is pre-populated by a communication service provider.
