Abstract
A reconfiguration message is received at user equipment in a communication system from a disaggregated base station with which the user equipment has a current security context established. The reconfiguration message comprises an instruction to compute a new security context based on a security domain counter value, wherein the security domain counter value represents a given security domain from a plurality of security domains supported by the disaggregated base station. The new security context is computed at the user equipment for the given security domain based on the security domain counter value. A set of security keys are derived from the new security context at the user equipment.
