Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and a first mission critical (MC) server are provided for managing security domain access information of migrated users in a private communication in MC services. A first MC server receives a private call request from an MC service user of a first UE for establishing the private communication with an MC service user of a second UE. It is determined whether the MC service user of the second UE is migrated from the first MC server to at least one secondary MC server. A private call redirection message is generated, and the private call redirection message is transmitted to the MC service user of the first UE to establish the private communication with the MC service user of the second UE based on the private call redirection message.
