Abstract: A solution for handling network congestion includes: attempting, by a user equipment (UE), to initiate a data session (e.g., a voice over WiFi (VoWiFi) call) over a packet data network (PDN); receiving, by the UE, a notification of network congestion; based on at least a fast retry timer and a fast retry counter, attempting, by the UE, fast retries up to a maximum number of fast retries at a fast retry time interval; and based on at least none of the initial attempt and the fast retries initiating the data session, attempting, by the UE, slow retries at a slow retry time interval until the data session is initiated or a trigger condition halts the slow retries. In some examples, the UE receives a retry parameter set from the network including the maximum number of fast retries, the fast retry time interval, and the slow retry time interval.

Abstract: While a first UE is engaged in an active call with a third UE, the first UE may receive an incoming call from a second UE. An option is presented on a display of the first UE to place this incoming call on hold. In response to receiving touch input selecting the option to place the second UE on hold, one or more communications may be sent to the second UE on hold, such as interactive or non-interactive video or audio. As a result, the call experience may be enhanced. In particular, the user of the first UE may no longer incur the stress that comes with either having to flip back and forth between calls or make a decision whether to decline an incoming call. And the user of the second UE may be more likely to wait on hold until the first call has ended.

Abstract: An orchestration and mediation (O/M) stack to be installed in a user device that subscribes to a carrier system is provided. The O/M stack configures the user device to receive a policy for accessing a plurality of different network slices that are logical networks virtualized on a physical infrastructure of the carrier system. The O/M stack configures the user device to coordinate each application's access to different services provided by the plurality of different network slices. An application is allowed access to a particular network slice when the application and the user device meet a condition specified by the received policy for accessing the particular network slice.
