Abstract: An alternating method, device and system for DTMF under separate structure are provided. The method includes: after a media process device (7) detecting the received DTMF signal, a media control device (6) indicating the media process device (7) to send the DTMF signal to a receiving end by H.245UserInput Indication message; or after a media process device (7) detecting H.245UserInput Indication message, a media control device (6) indicating the media process device (7), to transit the DTMF signal into the format accepted by the receiving end and send it to the receiving end. More precisely and reliably alternating of DTMF during multimedia session used in the multimedia resource in the moved network and the fixed network are received.

Abstract: A method, entity and system of media delivery control, by receiving the media resource information of a media delivery function entity, and according to the media resource information of a media delivery function entity, the media delivery function entity which can offer the media stream to a user is chosen; by the RTSP session communicated with the media delivery function entity, the media delivery function entity plays a media delivery action, a specific route that the MCF entity pairs to the MDF entity to control the media delivery is given, thus the need of the interface between the MCF entity and the MDF entity that support the media resource control function and the media stream control function are satisfied.

Abstract: A method and system for releasing the call during the multimedia service interconnecting in the separated framework, wherein, when due to a first network side which controlling the media flow without H.245 or a device with interconnecting function causes a call releasing, ends the H.245 session through the media control device and the media process device; after ending the session, indicates the network side which does not release the call to release the call, and release the bear on the media process device, further deletes the correspond session terminal. Therefore, when the IMS network and the CS network are intercommunicating the multimedia service, it is able to ensure that ending the H.245 session before releasing the multimedia call in the case of the SIP side terminal or the MGC initiating to release call, and the MG reporting SIP side bear to release call. Further, it may end the H.245 session by the means of indicating to close the appointed logical channel and then indicating to send ESC message.

Abstract: A method for transmitting media streaming control message includes acquiring a media streaming control message, and sending the media streaming control message to the media source processing device by H.248 protocol message. A system for transmitting media streaming control message includes media source control device and media source processing device. The media resource processing device is able to acquire the media streaming control message by sending the H.248 protocol message which carries the media streaming control message, or sending the media streaming control message through a tunnel established on the H.248 protocol, so that the media resource processing device may acquire the media streaming control message in such a architecture where the bearing is apart from the control.
