An apparatus, comprising: means for storing a flow management policy; means for determining, while the apparatus is attached to a first radio access technology, that an inter-radio access technology handover of the apparatus from the first radio access technology to a second radio access technology is likely or imminent; characterized by: means for evaluating, in response to determining the inter-radio access technology handover is likely or imminent, the flow management policy to determine a priority order between at least the second and a third radio access technology with respect to at least one first flow active between the apparatus and the first radio access technology, and means for causing at least one of the at least one first flow to be transferred, before the inter-radio access technology handover, to the third radio access technology responsive to a determination that for the at least one first flow, the third radio access technology has higher priority than the second radio access technology, wherein at least one second flow active between the apparatus and the first radio access technology is not caused to be transferred to the third radio access technology. means for storing a flow management policy; means for determining, while the apparatus is attached to a first radio access technology, that an inter-radio access technology handover of the apparatus from the first radio access technology to a second radio access technology is likely or imminent; characterized by: means for evaluating, in response to determining the inter-radio access technology handover is likely or imminent, the flow management policy to determine a priority order between at least the second and a third radio access technology with respect to at least one first flow active between the apparatus and the first radio access technology, and means for causing at least one of the at least one first flow to be transferred, before the inter-radio access technology handover, to the third radio access technology responsive to a determination that for the at least one first flow, the third radio access technology has higher priority than the second radio access technology, wherein at least one second flow active between the apparatus and the first radio access technology is not caused to be transferred to the third radio access technology. means for evaluating, in response to determining the inter-radio access technology handover is likely or imminent, the flow management policy to determine a priority order between at least the second and a third radio access technology with respect to at least one first flow active between the apparatus and the first radio access technology, and means for causing at least one of the at least one first flow to be transferred, before the inter-radio access technology handover, to the third radio access technology responsive to a determination that for the at least one first flow, the third radio access technology has higher priority than the second radio access technology, wherein at least one second flow active between the apparatus and the first radio access technology is not caused to be transferred to the third radio access technology.
