Network node and methods for selecting access node for communications in wireless communication networks

A network node for assisting a wireless terminal to select an access node for a communication in a wireless communication network, wherein the wireless communication network comprises a cellular network access node and a wireless local network access node, the network node comprising:

• an establishing circuit configured to establish a state of a wireless local network unit in the wireless terminal;
• an obtaining circuit configured to obtain information of at least one of:
• a radio condition of the wireless local network access node and the cellular network access node;
• a load condition of the wireless local network access node and the cellular network access node;
• a determining circuit configured to determine which access node to use, out of the wireless local network access node and the cellular network access node for the communication, based on the established state of the wireless local network unit and at least one of:
• the obtained radio condition of the wireless local network access node and the cellular network access node;
• the obtained load condition of the wireless local network access node and the cellular network access node;
• a transmitting circuit configured to transmit a control signal to the wireless terminal to set the wireless terminal to a reduced-power mode after the wireless terminal has communicated over the determined access node;
• wherein the wireless local network unit only performs radio condition measurements at predefined time instances that comply with a time pattern for monitoring paging messages from the network node by a cellular unit in the wireless terminal while the wireless terminal is set to the reduced-power mode.
