LTE: Detach Accept

·            The DETACH ACCEPT message is sent either by the network or the UE to indicate that the detach procedure has been completed

·            In the case of an UE initiated DETACH REQUEST , with the Detach type IE set to ‘switch off’, the network shall not send a DETACH ACCEPT message to the UE

·            If the network receives a DETACH REQUEST , with the Detach type IE set to ‘normal detach’, the network shall send a DETACH ACCEPT message to the UE

·            In the case of network initiated DETACH REQUEST, the UE shall send DETACH ACCEPT message, to indicate the successful completion of the detach procedure
