Abstract
Systems and methods are disclosed herein relating to wireless device behavior after rejection of a resume request triggered by a Radio Access Network (RAN) based Notification Area Update (RNAU) or upon cell reselection during resume. In some embodiments, a method of operation of a wireless device comprises transmitting, to a RAN node, a Radio Resource Control (RRC) resume request triggered by an RNAU and receiving, from the RAN node, an RRC resume reject message comprising a wait timer value in response to the RRC resume request. The method further comprises starting a wait timer initialized with the wait timer value and sending the RNAU when the wait timer has expired. Corresponding embodiments of a wireless device are also disclosed. Embodiments of a wireless device and methods of operation thereof related to the behavior of the wireless device upon performing a cell reselection during resume are also disclosed.
