A method for handling a PDN disconnection request performed by a communications apparatus communicating with a network device includes transmitting a PDN disconnect request message to the network device to request to disconnect a predetermined PDN connection; receiving a PDN disconnect reject message from the network device; obtaining a reject cause carried in the PDN disconnect reject message; and locally deactivating all other PDN connection(s) other than the predetermined PDN connection when the reject cause carried in the PDN disconnect reject message indicates that the last PDN disconnection is not allowed.
