Presented herein are techniques for detecting establishment of a bearer associated with a communication session offloaded from a mobile carrier network to a wireless local area network, such as a Wi-Fi® network, and sending, from the mobile carrier network to the wireless local area network, an indication of a level of quality of service (QoS) to be applied to a segment of the communication session that is conveyed by the wireless local area network. The indication of the level of QoS may be passed via a network controller.
