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: There are provided measures for reduction of in-device co-existence interference. Such measures exemplarily comprise (in a mobile network scenario allowing co-operation of a first radio access technology with a second radio access technology) detecting a need to avoid an in-device co-existence interference in relation to said co-operation, and performing at least one action for avoiding the in-device co-existence interference.

Abstract: A method and apparatus may include estimating a metric value relating to a first user equipment and an access point, without relying on actual data transmitted by the access point to the first user equipment. The method may also include estimating a quality degradation to the at least one second user equipment if at least part of the traffic of the first user equipment is routed to the access point. The method may also include performing routing of at least part of the traffic of the first user equipment based on the estimated metric value and the estimated degradation.

Abstract: The present disclosure relates generally to the field of wireless communications, and in particular to techniques for efficiently transferring, among network nodes, an access context required to initiate data transfer when a user equipment (UE) is in an active or suspended Radio Access Network (RAN) connection state. The techniques disclosed herein involve identifying, based on UE-specific data (such, for example, as mobility information, a traffic profile), one or more relevant network nodes where the UE in the suspended RAN connection state could be located at the time when next data transfer needs to be initiated. After that, the access context is sent from an anchor network node to said one or more relevant network nodes. By sending the access context in this manner, network signalling overhead and storage capacity overhead may be significantly reduced.
