The EBI is assigned to the EPS bearer only when the requirement is met. Otherwise, the EBI is not assigned to the EPS bearer or the EBI is released if the EBI has been assigned. In this way, when UE moves from a 5GS to the EPS, the EPS bearer is prevented from using an EBI that does not meet the user plane security requirement for data transmission.
