Abstract
Apparatuses and methods are disclosed for enabling signalling storm mitigation in Internet Protocol (IP) Security (IPsec)-secured virtual Radio Access Network (vRAN). In one embodiment a method in a first network node includes receiving a trigger to establish an IPsec session with a second network node, the IPsec session being associated with a user equipment (UE); responsive to the trigger to establish the IPsec session associated with the UE, derive a unique identifier for the UE; generate a Security Parameter Index (SPI) value based at least in part on the unique identifier derived for the UE, the SPI value being unique to the IPsec session; and communicate an indication of the SPI value to the second network node.
