Some demonstrative embodiments include devices, systems and/or methods of communicating Wireless Local Area Network (WLAN) offloading information between cellular managers. For example, a first cellular manager of a first cellular network may send to a second cellular manager of a second cellular network one or more WLAN offload parameters corresponding to Radio Access Network (RAN) assisted WLAN interworking information, which is sent to one or more User Equipment (UE) in the first cellular network.
