METHOD, APPARATUS AND SYSTEM OF PAGING Russian patent published in 2019 - IPC H04W76/10 

FIELD: physics.

SUBSTANCE: invention relates to paging. Providing, by the mobility management network element, obtaining UE location information in a non-3GPP network, wherein the UE is a UE, which already accesses the non-3GPP network; receiving a downlink data notification message, wherein the downlink data notification message carries the UE identifier; and paging the UE according to location information of the UE in the non-3GPP network. Embodiments of the present invention also provide a device and a paging system. In embodiments of the present invention, the paging range may be determined in accordance with location information of the UE in the non-3GPP network, and it is not required to send the paging message to all base stations in the UE registration area.

EFFECT: efficient reduction of paging signaling and saving of wireless interface resources.
