Abstract: A method for providing access feedback when a User Equipment, UE, with an established a connection over multiple accesses towards a Gateway, GW, initiates a set-up of a new service for a service session. The method comprises a step where the GW or a Policy and Charging Rules Function, PCRF, initiates a Quality of Service, QoS, resource reservation as a response of the set-up of the new service initiated by the UE. The GW or the PCRF in the QoS resource reservation selects a first access as present access. The method is particularly characterized in a step where the UE rejects said first access as present access and sends a reject message to the GW, wherein the GW or the PCRF as a result of the reject message initiates a new QoS resource reservation selecting a second access as present access.

Abstract: A first network node controls WLAN accesses and a second network node controls cellular network accesses. The first network node (NN) records a time of a last radio contact event of a user equipment (UE) with respect to a WLAN access controlled by the first NN. In response to a request from a third NN, the first NN indicates the recorded time of the last radio contact event to the third NN. The second NN records a time of a last radio contact event of the UE with respect to a cellular network access controlled by the second NN. In response to a request from the third NN, the second NN indicates the recorded time of the last radio contact event to the third NN. The third NN can use the indicated times to determine whether the UE is attached to a WLAN access or to a cellular network access.
