PERSONALIZED USER SESSION INFORMATION FOR CALL HANDOFF

摘要

Techniques for hosting a communication session between a first communication device and a second communication device in an IP network are described. A contact server establishes separate communication links between itself and the communication devices wherein the communication links may traverse one or more telephony networks. The contact server receives personalized user session data generated by a user of a communication device. The personalized user session data may be indicative of a subjective evaluation of the quality of the communication link or a preference for a particular telephony network. The contact server may then cause the communication device to establish a new communication link with the contact server and handoff from its current communication link to the new communication link when the subjective evaluation of the quality of the communication link crosses a threshold level or a condition for a preference for a particular telephony network is detected.
