An object of the present disclosure is to provide an access network node, a user equipment, a network function node and a control method capable of steering a UE in connected mode. In one example aspect, a control method for an access network node includes: receiving, from a network function node for mobility management, at least one first network slice information, each of which is different from a second network slice information being used for a Protocol Data Unit, PDU, session with a user equipment, UE; and performing a redirection procedure for the UE from a first cell to a second cell which supports one of the at least one first network slice information in a case where the second network slice information is not available in the first cell.
