Table: CoA and Disconnect Message: WLAN-GW migrant users identification attributes details the attribute that can be used in a CoA and Disconnect Message to target migrant users. A Disconnect Message removes any existing migrant state for the specified UE. A CoA can only be sent for a UE in portal state to trigger the creation of an ESM or DSM user. In contrast to most CoAs this update is not incremental: the CoA must include all required authentication attributes to create the user. The applicability of attributes is the same as for an Access-Accept message in an authentication procedure.
