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.

Abstract: The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding an optimized time-to-trigger for WLAN radio interworking. The present invention comprises defining, by a network element, a timer value indicating a time period during which rules for traffic management by a user equipment have to be fulfilled before the user equipment is allowed to start the traffic management, the traffic management including network selection of initiating a communication session in a communication network according to a first radio access technology and traffic steering of switching a communication session from the first communication network according to the first radio access technology to a second communication network according to a second radio access technology, wherein the timer value to be applied for network selection differs from the timer value applied for traffic steering, and transmitting, by the network element, the timer value to the user equipment.

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.
