Abstract
A wireless UE wirelessly attaches to a network controller over a source RAN. The UE transfers UE capabilities that comprise a Public Land Mobile Network Identifier (PLMN ID) and transfers a slice request for a network slice type to the network controller over the source RAN. The network controller selects a network slice based on the requested network slice type. The network controller selects a mobility profile that comprises handover criteria based on the requested slice type and the PLMN ID. The UE exchanges user data with a user plane over the selected network slice. The UE determines a handover requirement based on the handover criteria and identifies a set of target RANs. The UE selects one of the target RANs based on the handover criteria and hands over to the target RAN. The UE exchanges additional user data with user plane over the network slice and the target RAN.
