SYSTEM AND METHOD FOR SWITCHING A COMMUNICATION CHANNEL FROM A DATA NETWORK TO A CELLULAR NETWORK DURING OBSERVED AUDIO/VIDEO QUALITY DEGRADATION

摘要

A mobile device joins a communication session using a data communication channel. A determination is made the data communication channel uses a data network of the mobile device. A determination is made that, during the communication session, a quality of the data communication channel has decreased. In response to determining that the data communication channel uses the data network of the mobile device and determining that the quality of the data communication channel has decreased, a push notification message is sent to a push notification service. The push notification message comprises a cellular network dial-able number that is used by a cellular application in the mobile device to initiate a call to join the communication session via a cellular communication channel that uses a cellular network.
