SYSTEMS AND METHODS FOR TRANSITIONING A TELEPHONY COMMUNICATION BETWEEN CONNECTION PATHS TO PRESERVE COMMUNICATION QUALITY

摘要

An IP telephony communication being conducted by a user telephony device is transitioned from an IP based communications path to a cellular based voice or video communications path if a quality of the telephony communication falls below a threshold level. The user telephony device and/or elements of an IP telephony system handling the call could detect when the quality is below the threshold level. The communication might also be transitioned to a cellular based voice or video communications channel if the strength of a wireless connection between the user telephony device and a wireless access point providing access to a data network falls below a threshold level.

1. A method, performed by one or more processors of an Internet Protocol (IP) telephony system, for transitioning a communications path of a telephony communication from an IP based communications path to a cellular based communications path, comprising:
determining whether a quality of a communication which is traversing an IP based communications path between a user's telephony device and an IP telephony system has fallen below a threshold; causing a cellular based communications path to be setup between the IP telephony system and the user's telephony device if the determining step indicates that a quality of the communication has fallen below the threshold; and transitioning media of the communication from the IP based communications path to the cellular based communications path.
