During handover of a radio terminal (1) from a first network to a second network, a target RAN node (3) is operates to: receive, from a core network (5), slice information about a network slice which is included in the second network and to which the radio terminal (1) is to be connected; create, upon receiving the slice information, radio resource configuration information that is to be used by the radio terminal (1) after the handover in the second network; and transmit this radio resource configuration information through the first network to the radio terminal (1). It is possible to contribute to appropriately configuring an AS layer or NAS layer of a target RAT in inter-RAT handover.

Devices, systems, and methods for optimizing a mesh network by cloud computing. A cloud network controller may receive from multiple access points (APs) in a mesh network information related to channel quality based on measurements taken by the APs. Based on this information, the cloud network controller may forecast one or more optimal channels based on the information related to channel quality. The cloud network controller my then send to the multiple APs a message including a recommendation to switch to the one or more optimal channels based on the forecasting. The AP may then make a decision to carry out the recommended channel switch.

There is provided a method in a controlling node to efficiently assign spectrum to nodes representing wireless base stations which are using/sharing the same block of spectrum. The nodes are organized in a graph where connections between nodes represent potential of interference. The nodes are grouped based on the ability to handle mutual interference. The method comprises: determining recursively a plurality of clusters of nodes of increasing sizes; and assigning a bandwidth to nodes in each cluster, based on the size of the cluster. By so doing, the spectrum allocation can be optimized, allowing each node access to an increased amount of spectrum.

A network component of a radio access network (RAN) is configured to provide network slice information to a user equipment (UE). The network component receives an indication that a user equipment (UE) is requesting to access a network slice, determines a frequency associated with the network slice, identifies a cell within the RAN that operates on the frequency associated the network slice and transmits a message to the UE, wherein the message indicates the cell within the RAN that operates on the frequency associated with the network slice.

A method, a device, and a non-transitory storage medium are described in which a network slice-to-transport domain service is provided. The service includes correlating a network slice identifier, an Internet Protocol subnet, and a virtual routing and forwarding instance pertaining to a network slice, and configuring network devices of the network slice with at least a portion of the correlated information. The service may obtain feedback information from the network devices, and evaluate performance metrics pertaining to the network slice based on the correlated information.
