name: T3220
full_form: Timer 3220
context: If the MS deems that the network has failed the authentication check, then it shall request RR or RRC to release the RR connection and the PS signalling connection, if any, and bar the active cell or cells (see 3GPP TS 25.331 [23c], 3GPP TS 25.304 [98] and 3GPP TS 44.018 [84]). The MS shall start any retransmission timers (e.g. T3210, T3220 or T3230), if they were running and stopped when the MS received the first AUTHENTICATION REQUEST message containing an invalid MAC or invalid SQN, or no AUTN when a UMTS authentication challenge was expected.
description: The T3220 is another retransmission timer that starts under similar conditions as the T3210.
explanation: Categorized as a Timer because it measures time intervals for retransmissions.
