Question: What action does an en-gNB take when receiving an SGNB MODIFICATION REQUEST with multiple E-RAB ID IEs set to the same value in the E-RABs To Be Released List IE?
Option 1: Admit the action for all corresponding E-RABs
Option 2: Reject the entire SGNB MODIFICATION REQUEST procedure
Option 3: Initiate release of one corresponding E-RAB and ignore duplicate instances
Option 4: Request additional information before proceeding with the modification
Explanation: When an en-gNB receives a modification request with duplicated E-RAB IDs in the release list, it initiates the release of one corresponding E-RAB and ignores the duplication of instances. This ensures at least one instance of the intended action is executed while preventing potential conflicts from duplicates.
