Abstract

See full text

The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.
