Problems solved by technology

[0007] When a user uses a terminal device that supports audio, video, auxiliary stream, etc. to access the MCU, only one call is required between the terminal device and the MCU. However, if the user uses multiple terminal devices to join the videoconferencing system, and each terminal device only If one media type is supported, the multiple terminal devices need to establish one call with the MCU respectively, and one user will establish multiple calls, occupying multiple ports of the MCU, wasting the port resources of the MCU

Abstract

The embodiment of the invention discloses a call processing method and a gateway, which are used for the gateway to process the call between the MCU and the terminal equipment. The method in the embodiment of the present invention includes: the gateway receives a call initiated by a terminal device; the gateway negotiates with the terminal device, establishes a first call between the gateway and the terminal device, and negotiates to determine the first call Media type; add the negotiation of the media type of the first call in the established call between the gateway and the multipoint control unit MCU, wherein the first call and the established call have different media type, so that the negotiation of the media type of the call is added to the established call between the gateway and the MCU, which can effectively reduce the number of calls established by the MCU and save the port resources of the MCU.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a call processing method and a gateway. Background technique [0002] Video service is a multimedia service that integrates voice, image, data and other information together for long-distance transmission. The service provided by video service is video conferencing, which can include images, voice and data. You can not only hear the voice of the other party, but also see the image of the other party, which enhances the sense of reality, emotion and presence of the communication, and the video service can be used in military, political, economic, education, health and other fields to give full play to the reality. , high efficiency, and real-time advantages, providing people with simple and effective means of communication, management, and collaborative decision-making. [0003] Conference TV service is a kind of video conferencing service, which is a communication method ...
