Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first authentication request in response to a first triggering request from the UE to a mobility management node of a first Tracking Area (TA) in which the UE is located. In some embodiments, the UE may prepare and store an authentication response according to the first authentication request. In response to determining that the UE has moved from the first TA to a second TA, the UE may abort a sending of the authentication response, and may send the stored authentication response according to the first authentication request to the mobility management node of the second TA in response to the receipt of the second authentication request and in further response to a determination that a given parameter of each of the first and second authentication requests are the same.
