Claim 0:
1. A wireless user device comprising:
at least one antenna to transmit and receive one or more wireless signals;
at least one processor; and
memory storing instructions that, when executed by the at least one processor, cause the wireless user device to:
receive first radio access network-based notification area (RNA) information, wherein the wireless user device is in a radio resource control (RRC) inactive mode;
receive, from a base station:
second RNA information different from the first RNA information; and
an access barring threshold value;

based on a difference between the first RNA information and the second RNA information and based on the access barring threshold value, determine that an RNA update indication is allowed;
transmit, to the base station and based on determining that the RNA update indication is allowed, an RNA update indication message;
receive an RNA update reject message responsive to the RNA update indication message; and
after receiving the RNA update reject message and while a timer is running, start a cell reselection.
