Embodiments are directed to a network-connection report is received at a server (e.g., a presence server) from a first user equipment (UE) that identifies a type of physical-layer network to which the first UE is connected. In response to a determination that the first UE is engaged in a communication session with a second UE, the server sends a notification message to the second UE that indicates the type of physical-layer network to which the first UE is connected. The second UE receives the notification message and determines a target physical-layer network for supporting the second UE's participation in the communication session based at least in part on the type of physical-layer network to which the first UE is connected. The second UE selectively transitions to the target network based on the determination. |
