Abstract: There are provided measures for enabling/realizing interface functionality for RAN-WLAN radio aggregation, i.e. radio level integration/aggregation between a cellular radio access network and a wireless area network. Such measures exemplarily comprise user-plane data forwarding from a cellular radio access network over a wireless local area network to a terminal, both the cellular radio access network and the wireless local area network providing radio level connectivity for the terminal, wherein in the user-plane data forwarding user-plane data packets according to a cellular data convergence protocol are transported, at least partly, using a reliable transport protocol over the wireless local area network to the terminal, providing feedback on performance of user-plane data packets transport using the reliable transport protocol, at least partly, from the wireless local area network to the cellular radio access network, and executing flow control on the basis of the performance feedback.

Abstract: Offloading Mechanism Using Load-Dependent Offloading Criteria Various communication systems may benefit from load adjustments, such as on-loading or off-loading. For example, third generation partnership project, 3GPP, and wireless local area network, WLAN, systems may benefit from a load-dependent load adjustment mechanism. A method can include obtaining (110), at a user equipment, at least one load-dependent criteria for load-adjusting. The interworking rule can relate to a mobile net work and a local area network. The method can also include applying (120), by the user equipment, the at least one load-dependent criteria when load-adjusting.

Abstract: Systems and techniques for changing between secondary cells in dual connectivity communication. A user device (110A) operating in dual connectivity with a master base station (102) and a source base station (106A) transmits a change request to a target secondary base station (106B), seeking a connection change to a target base station that is to be used as the secondary base station. The target base station (106B) notifies the master base station (102) of the change request, and the master base station performs changeover operations—for example, notifying the source base station (106A) that it is no longer to be used in dual connectivity with the user device (110A) making the request, and notifying the user device (110A) that the change request has been accepted, with the user device (110A) then proceeding to establish connection with the target secondary base station (106B).
