Section: 12.3.9.3.3 Based on session parameters
Content: Message prioritization may be performed based on the session parameters, such as: APN, QCI, ARP and/or Low Access Priority Indicator (LAPI). The procedures and messages associated with the higher priority sessions shall be given lesser preference whilst throttling, as compared to the procedures and messages associated with the lower priority sessions. Within each group of sessions, the messages may be further prioritized based on the category of the procedure for which the message is being sent (as described in clause 12.3.9.3.2). NOTE: This type of prioritization scheme ensures a good handling of all the messages and procedures related to higher priority sessions but can lead to throttle messages related to a critical procedure, e.g. UE mobility, for lower priority sessions over messages related to less critical procedures, e.g. location reporting, for a higher priority session.
