An AMF apparatus () receives a NAS message for requesting a core network to establish or activate a PDU session associated with an allowed network slice identifier, from a UE (), via a first cell () not supporting the allowed network slice identifier and via a first AN node () that provides the first cell (). In response to receiving the NAS message, the AMF apparatus () sends to the first AN node () a control message that causes the first AN node () to move the UE () to a second cell () that supports the allowed network slice identifier. This can contribute, for example, to enabling an establishment or activation of a PDU session associated with a network slice that is supported only in sparsely (or patchily) placed local cells.

AMF apparatus, access network node, and methods therefor
