Apparatus and method for intelligent routing of data between a remote device and a host system

(57) Equipment and a method are offered for the transparent communication between the device of a summary remote place or a mobile device, and a fixed communication host network. The equipment and method may contain the remote network controller which exists logically between a host network and the infrastructure which are used in order to offer the communication network connection with the device of one or more remote places, and which exists. A remote network controller is connected to a host communication network as a communication controller corresponding to a protocol so that the device of a remote place may not be distinguished from the device prepared in the specified position for the host network. The device of each remote place may be equipped with the asynchronous serial-data interface in order to communicate with a mobile-data controller. In combination with a remote network controller, a mobile-data controller offers end-to-end data communications so that a protocol without compatibility may be transparent to the device and host communication network of a remote place. The router which chooses a communication network according to the parameter which the user constituted may be offered. The router can communicate ranging over a network without two or more compatibility, and various different protocols can be used for it. The change between networks without two or more compatibility is transparent to the device and host communication network of a remote place.
