Abstract
Systems and methods are provided for rapid user equipment route selection policy rule processing. A method includes determining an applicable routing policy based on user equipment route selection policy (URSP) rules for an established protocol data unit (PDU) session and storing PDU session information with the established uplink PDU session in a cache. The method further includes examining subsequent uplink packets for PDU session information and checking the cache for an established PDU session with matching uplink PDU session information. The method additionally includes routing the subsequent uplink packets to the established PDU session having the matching PDU session information, causing the subsequent uplink packet to be processed in accordance with the applicable routing policy as previously determined based on the URSP rules.
