  • Patent number: 11950157
    Abstract: Methods, nodes and computer program products control radio channel deployment when using un-licensed carriers in a wireless communication network and control mobility and/or load balancing target selection when using un-licensed carriers. When performed in an access node, unlicensed carrier intrinsic cell channel load is determined in a cell served by the access node based on one or more predetermined channel load indicators and neighbor cell channel load information is obtained, from one or more neighboring access nodes. The neighbor cell channel load information includes unlicensed carrier channel load in respective cells based on the one or more predetermined channel load indicators. At least one channel deployment operation is initiated based on an outcome of one or more comparative operations including the determined unlicensed carrier intrinsic cell channel load and/or the obtained neighbor cell channel load information.

  • Publication number: 20220286924
    Abstract: Systems and methods are disclosed for providing a network-instructed handover of a wireless device from a Wireless Local Area Network (WLAN) to a Radio Access Network (RAN) of another Radio Access Technology (RAT), e.g., a 3rd Generation Partnership Project (3GPP) or 3rd Generation Partnership Project 2 (3GPP2) RAT. In one embodiment, a WLAN access node determines that a handover of a wireless device from the WLAN to another RAN of a different RAT is to be performed and transmits a handover instruction to the wireless device that instructs the wireless device to perform a handover from the WLAN to a RAN of a different RAT. In this manner, the WLAN access node is able to steer the wireless device from the WLAN to a RAN of a different RAT.
