1. A method of a node configured to provide core network user plane functionality in a communications network to enable paging of a wireless communication device being in an idle state, the method comprising:
receiving an indication that data is to be transmitted in downlink to the wireless communication device;
identifying, in response to the received downlink data indication, a radio access network control plane function;
sending, to the identified radio access network control plane function, a downlink data notification comprising an identifier of the wireless communication device and of a core network control plane function configured to provide mobility management where the wireless communication device currently is registered, thereby enabling for the identified radio access network control plane function to forward the download data notification to the identified core network control plane function configured to provide mobility management to enable the identified core network control plane function configured to provide mobility management to page the wireless communication device.
