A wireless local area network, WLAN, node (400) is adapted to be comprised in an integrated wireless communications network comprising a WLAN and a cellular communications network. The WLAN node (400) comprises a receiving module (401) adapted to receive traffic data from a wireless device. A differentiation module (403) is adapted to determine whether the received traffic data relates to a first traffic type which is to be routed locally within the WLAN or a second traffic type which is to be routed to the cellular communication network. A processing module (405) is adapted to control the handling of the traffic data according to whether the traffic data is determined as relating to the first traffic type or the second traffic type.
