A method for supporting downlink paging for LIPA or SIPTO while a first UE has been moved to an idle mode may include monitoring UE traffic while the first UE is in the active state and storing a UE IP address for a default EPS bearer of the first UE in a node and in a gateway for LIPA or SIPTO service. A downlink datagram for paging activation is sent towards the first UE over an existing tunnel, wherein the tunnel was established for a second UE being in an active state, wherein the tunnel may be established for the second UE or any other UE served by the same node and the same gateway, and activating a paging procedure by receiving the downlink datagram via the tunnel in a gateway, which gateway is serving the first UE for the default EPS bearer service of the first UE.
