Some demonstrative embodiments include devices, systems of tunneling data radio bearers via a wireless local area network link. For example, an Evolved Node B (eNB) may communicate with a User Equipment (UE) traffic of a plurality of Data Radio Bearers (DRBs) via a cellular link; establish an offloading tunnel between the UE and the eNB to tunnel the DRBs via a Wireless Local Area Network (WLAN) link, the offloading tunnel including one or more User Datagram Protocol (UDP) tunneling connections configured to differentiate between the plurality of DRBs; and coordinate with the UE a handover of at least one DRB of the plurality of DRBs to the offloading tunnel.
