A communication method, a signaling control network element, a media control network element and a communication system. The communication method comprises: acquiring a transparent transmission channel creation request; performing, according to the transparent transmission channel creation request, negotiation processing on a media control network element and a first terminal device corresponding to a first terminal identifier, so as to create a transparent transmission channel between the media control network element and the first terminal device; obtaining a first resource identifier of an application entity according to the transparent transmission channel creation request; and sending the first resource identifier to the media control network element, so that the media control network element determines a data transmission relationship between the transparent transmission channel and the application entity corresponding to an application identifier.

The present invention discloses a route service device and a method and a system for realizing call route by the device, in which, route service device and soft switch control device are networked in a layered way, the soft switch control device is the node of the lowest layer, when the user route changes, the soft switch control device reports route information including user node to the father node; the route service device performs registration, and broadcasts the changed route information to the father node, each related route service device performs registration and broadcast by the same way; when calling across domains, the soft switch control device where the calling locates initiates inquiry toward the father node, and receives the returned inquiring result, therefore routing the call to the soft switch control device where the called locates. The present invention employs route service device to replace soft switch control device for performing call route function, therefore enabling the soft switch control device absorbed in providing services, and also providing a scheme of large scale networking at telecommunication level for soft switch control device.

The present invention relates to a method of controlling the roam of a terminal user in the NGN network system, including: dividing the network into regions in accordance with IP address field and defining the roam type and service attribute of each IP address field when the terminal user roams to each region; defining the roam right of the terminal user in a core control device according to the roam type; when the terminal registers with the core control device from a region, IP address of the terminal being uploaded to the core control device, and the core control device obtaining the roam type of the terminal in accordance with the IP address of the terminal; then judging whether the terminal user has such roam right of this roam type, if positive, the terminal registering successfully, otherwise failing; when the terminal registers successfully, the terminal user is able to use the network service and some service attributes in the region. By adopting the method of the present invention, it is possible that the core control device can control and manage the access of the terminal user to different regions.
