name: T3323
full_form: Timer for Mobile Originated Signaling in Idle Mode
context: The UE with its TIN set as "RAT-related TMSI" for which ISR is activated shall change its TIN to "GUTI" to locally deactivate ISR and stop the periodic routing area update timer T3312 or T3323, if running:
  -	upon modification of any EPS bearer context which was activated before the ISR is activated in the UE;
  -	at the time when the UE changes from S1 mode to A/Gb mode or Iu mode not due to PS handover procedure (see 3GPPÂ TSÂ 24.008Â [13]), if any EPS bearer context activated after the ISR was activated in the UE exists; or
  -	upon deactivation of the last non-emergency EPS bearer context in the UE, if the UE has only a PDN connection for emergency bearer services remaining.
  ISR remains activated on the network side in the above cases.
description: Another timer related to managing periodic routing area updates or mobile-originated signaling when the UE is in idle mode.
explanation: Categorized as a Timer because it controls timing of mobile-initiated network interactions.
