1. A method performed by a radio access network (RAN) node of a wireless communication system, the method comprising:
receiving, from a wireless device via a cell, a request to resume a Radio Resource Control (RRC) connected state with the wireless communication network, wherein the request includes a cause indicator that indicates mobility signaling as a cause for resuming the RRC connected state;
based on the cause indicator, requesting an access and mobility management function (AMF) of the wireless communication system to perform a tracking area update (TAU) for the wireless device;
receiving from the AMF an indication that the TAU for the wireless device is complete; and
in response to the received indication, initiating an access-stratum (AS) procedure for the wireless device.
