Abstract:
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 a 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.
