Abstract

See full text

A solution for handling network congestion includes detecting, by a wireless network, a network congestion condition; detecting, by the wireless network, a failed attempt, by a user equipment (UE), to initiate a data session (e.g., a voice over WiFi (VoWiFi) call) over a packet data network (PDN) through the wireless network; transmitting, by the wireless network, to the UE, a notification of network congestion; and transmitting, by the wireless network, to the UE, a retry parameter set including a maximum number of fast retries, a fast retry time interval, and a slow retry time interval. In some examples, the retry parameter set further includes a rate at which the slow retry time interval increases with a value of a slow retry counter, and/or a maximum number of slow retries. In some examples, the retry scheme varies based on the severity of the congestion and/or roaming conditions.
