The present invention discloses a video communication method and system, wherein, during an audio conversation between a calling party and a called party, an IMRS (Integrated Media Resource Server) plays a video to the calling party or the called party; or when a calling party initiates a video phone call request to a called party which does not support video phone call, an audio channel is established between the calling party and the called party and a video channel is established between the calling party and an IMRS, and when an audio conversation is established between the calling party and the called party, the IMRS plays video to the calling party; or when an audio conversation and a video conversation are established between a calling party and a called party, one party replaces its video with that played to the other party by the IMRS, therefore capabilities of developing new communication services are improved.

Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.
