Claim 8:
9. A computing apparatus of a user equipment (UE), the computing apparatus comprising:
a processor; and
a memory storing instructions that, when executed by the processor, configure the computing apparatus to:
process a first authentication request received at the UE 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;
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:
abort a sending of the authentication response;
abort the first triggering request;
prepare a second triggering request to be sent from the UE to a mobility management node of the second TA;
process a second authentication request received at the UE from the mobility management node of the second TA in response to the second triggering request; and
retrieve the stored authentication response according to the first authentication request, the stored authentication response to be sent by the UE to the mobility management node of the second TA in response to 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.
