Abstract

See full text

A base station transmits to a wireless device, a first message indicating a RRC state transition of the wireless device from an RRC connected state to an RRC inactive state. The first message indicates a value associated with a wireless device radio-access-network notification area (RNA) update timer for a periodic RNA update procedure. The base station receives an RNA update from the wireless device in response to expiry of the wireless device RNA update timer. A determination is made that the periodic RNA update is unsuccessful based on expiry of a network RNA update timer. A second message is transmitted by the base station to an AMF in response to the determination. The second message indicates a wireless device context release request for the wireless device. The second message comprises an identifier of the wireless device.
