Abstract: A call processing method and a gateway are disclosed, where the gateway is configured to process a call between a multipoint control unit (MCU) and a terminal device. The method includes receiving, by the gateway, a call initiated by the terminal device; negotiating, by the gateway, with the terminal device, to establish a first call between the gateway and the terminal device and determine a media type of the first call; and adding the negotiated media type of the first call to a call established between the gateway and the MCU, where the media type of the first call is different from that of the established call. In this way, the negotiated media type of the call is added to the call established between the gateway and the MCU.

Abstract: A method, a device, and a network system for controlling multiple auxiliary streams are disclosed. The method for controlling multiple auxiliary streams includes: applying, by a terminal at a first site, for a presentation (PRE) token; and sending, by the terminal at the first site after applying for and obtaining the PRE token, an auxiliary stream to a terminal at a second site through a PRE auxiliary stream channel corresponding to the PRE token, and sending one or more other auxiliary streams to the terminal at the second site through an auxiliary stream channel bound with the PRE auxiliary stream channel. By using the technical solutions provided in the embodiments of the present invention, participants at the sites can view images of multiple auxiliary streams simultaneously.

Abstract: The present invention, relating to the field of communications, discloses a method, device and system for call establishment, wherein the method includes: obtaining the pre-configured binding relationship between conference rooms and terminals; setting the correspondences between terminals of a calling conference room and terminals of a called conference room according to said binding relationship; and establishing media communication with the terminals provided with the correspondences. Embodiments of the present invention also provide a call establishment device and a call establishment system. Embodiments of the present invention overcome various limits and defects due to the fact that calls between other corresponding terminals can only be established via a particular terminal in each conference room in the prior art, and enable a code stream to be transmitted in the shortest path, thereby greatly reducing the path delay and improving the video conference system scalability.
