Method and arrangement for controlling connection in communication networks

Method and arrangement for enabling a UE (User Equipment) to access a WLAN (Wireless Local Area Network). The UE detects a need for the UE to access the WLAN. Furthermore, the UE creates an ARC (Association Reason Code) based on the detected need, and sends the ARC to a WLAN node of the WLAN, such that the UE is thereby enabled to connect to the WLAN in accordance with the ARC. By implementing functionality in a UE to create an association reason code and send the association reason code to a WLAN node, an operator of a communication network will be able to influence and control connection of the UE to the WLAN node. Thereby, the operator will be able to effectively make use of installed communication resources.
