In an aspect, a method of a node (228) configured to provide core network user plane functionality in a communications network (200) to enable paging of a wireless communication device (210) being in an idle state is provided. The method comprises receiving (S101) an indication that data is to be transmitted in downlink to the wireless communication device (210), identifying (S102), in response to the received downlink data indication, a radio access network control plane function (225) to which the wireless communication device (210) was connected before entering the idle state, and sending (S103), to the identified radio access network control plane function (225), a downlink data notification comprising an identifier of the wireless communication device (210), thereby enabling for the identified radio access network control plane function (225) to trigger paging of the wireless communication device (210).
