发明名称 Network node and methods for selecting access node for communications in wireless communication networks
摘要 A method in a network node 150 for assisting a wireless terminal 145 to select an access node for a communication in a wireless communication network 100.The wireless communication network comprises a cellular network access node 130 and a wireless local network access node 140.The network node 150 establishes a state of a wireless local network unit 210 in the wireless terminal, obtains information of a radio condition and/or a load condition of the respective wireless local network access node and cellular network access node, and then determines 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 the obtained radio condition and/or load condition of the respective wireless local network access node and cellular network access node.

主权项 1. A method, in 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 method comprising: establishing, by the network node, a state of a wireless local network unit in the wireless terminal; obtaining, by the network node, 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; determining, by the network node, which access node to use out of the wireless local network access node and the cellular network access node for the communication, the determining 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; transmitting 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.
