Adaptive paging in wireless communication networks
A user equipment requests from a RAN node skipping of paging occasions that the RAN node otherwise may schedule for UEs uniformly throughout the area that the RAN serves. The RAN assigns the UE to a device-type classification based on battery parameters or service type of the UE. The RAN modifies scheduling of paging occasions to the UE, and others in a class that comprises the UE, based on the device-classification. The UE may submit to the RAN defined types of traffic, paging occasions for which the UE should not skip. The RAN may transmit in a paging skipping preemption search space an indication for the UE not to skip an upcoming configured paging occasion configured for skipping. The RAN may configure the UE with a paging pattern to use when UE conditions change, such as when an idle UE moves into range of another RAN.
