Transition from packet-switched to circuit-switched connection based on communication quality

摘要

Techniques for transitioning a synchronous communication engaged in by a telecommunication device from a packet-switched connection to a circuit-switched connection are described herein. The techniques include either or both of the telecommunication device or the telecommunication network determining a quality metric for a synchronous communication based at least in part on monitoring of the synchronous communication, the synchronous communication being transmitted using a packet-switched connection associated with the telecommunication network. Based at least in part on the quality metric, the telecommunication network and telecommunication device switch the synchronous communication from the packet-switched connection to a circuit-switched connection associated with the telecommunication network.

主权项

1. One or more devices of a telecommunication network, comprising:
a first device to determine a quality metric and to provide the quality metric in a presence update message, wherein the first device is one of a session border controller (SBC) or a media gateway; a presence server to receive the quality metric in the presence update message and to post the quality metric to subscribed devices of the telecommunication network; and a second device to receive the posted quality metric and, based at least in part on the posted quality metric, to fork voice call over a circuit-switched connection associated with the telecommunication network to cause a telecommunication device to use the circuit-switched connection in place of a packet-switched connection, wherein the second device is one of a telephony application server (TAS) or a mobile switching center (MSC).
