Abstract
In an embodiment, a server exchanges session data between a group of session participants during a communication session, the exchanged session data including session media and/or session signaling information. The server stores at least a subset of the exchanged session data. Later, the server establishes a connection to a given user equipment (UE) (e.g., either after or during the communication session). The server determines a UE-defined context that is indicative of a manner by which missed session data from the communication session is to be compressed for delivery to the given UE. The server selectively compresses at least a portion of the stored subset of the exchanged session data that was missed by the given UE based on the UE-defined context, and transmits the selectively compressed portion of the stored subset of the exchanged session data to the given UE.
