Claim of US Patent No. 10,560,978

1. A method for assigning control plane connectivity (CP) for a wireless device in a dual connectivity supported communications network, wherein the communications network comprises a first network node supporting a group of low frequency bands and a second network node supporting a group of high frequency bands, the method being performed by a control node, the method comprising:acquiring an uplink load level for the group of low frequency bands;
acquiring a first pathloss level between the wireless device and the first network node and a second pathloss level between the wireless device and the second network node; and
selecting which one of the first network node and the second network node to provide control plane connectivity (CP) for the wireless device,
wherein said selecting takes into consideration each of the uplink load level for the group of low frequency bands, the first pathloss level, and the second pathloss level.
