1. An apparatus comprising:
a processor configured to cause a user equipment device (UE) to:
register with a cellular public land mobile network (PLMN) using both a 3GPP and a non-3GPP access;
detect a trigger to provide an updated radio capability;
in response to detecting the trigger to provide the updated radio capability, determine if one of these conditions is true:
the non-3GPP access is in a connection management (CM)-connected state and the 3GPP access is not in the CM-connected state; or
the non-3GPP access is in the CM-connected state, the 3GPP access is in the CM-connected state, and a critical procedure is not ongoing; and
based on the determination:
if one of the conditions is true, provide, to the cellular PLMN, the updated radio capability, wherein the updated radio capability is provided during a registration procedure using the non-3GPP access; and
otherwise, perform one or more of:
delay providing, to the cellular PLMN, the updated radio capability; or
provide, to the cellular PLMN, the updated radio capability, using the 3GPP access.
