Problems solved by technology

[0002] At present, video conferencing systems operate in various Internet environments. The network environment is complex and diverse, and it is difficult to guarantee that there will be no abnormalities. The abnormalities include network line interruption and serious packet loss. The existing packet loss compensation technology can resist certain A certain degree of packet loss rate, at the cost of sacrificing a certain degree of picture quality
[0003] Many conferences have a high level of importance, and it is necessary to do a good job in environmental adaptability or backup. Most of the existing technologies take into account the backup of the Multipoint Control Unit (MCU) at the central office, such as the backup of the entire MCU, various Board backup, terminal backup, these backups all require at least two copies of physical hardware on the device, and network backup also requires the establishment of multiple links at the same time, requiring multiple sessions to be opened at the same time, resulting in a waste of bandwidth, which is equivalent to Guaranteed meeting in exchange for resources

Embodiment 1

[0037] figure 1 It is a flow chart of a method for realizing conference hot backup provided by an embodiment of the present invention, as shown in figure 1 As shown, the steps include:

[0038] Step S101: setting a first network port for accessing the first network and a second network port for accessing the second network as backups on the conference terminal.

[0039] The first network port for accessing the first network and the second network port for accessing the second network have the same IP address, so that it is guaranteed to be backed up to another network when an abnormality occurs in one network.

[0040] Step S102: the conference terminal detects the state of the first network in real time during the video conference using the first network port to access the first network.

[0041] In this embodiment, the state of the first network is detected in the following two ways:

[0042] Method 1: Network port anomaly detection

[0043] During the video conference, ...

Embodiment 2

[0051] The embodiment of the present invention also provides a device for realizing conference backup function, including:

[0052] The first network port set on the conference terminal is used to access the first network;

[0053] The second network port set on the conference terminal is used to access the second network;

[0054] The state detection module is used to detect the state of the first network in real time during the period when the conference terminal uses the first network port to access the first network to conduct a video conference, specifically by detecting the state change of the network port and / or The packet loss rate of the media stream determines whether the state of the first network is normal or not. For example, if the state change of the first network port is detected, it indicates that the network port of the first network is abnormal. If the packet rate is greater than the preset threshold, it indicates that the line of the first network is abnor...

Embodiment 3

[0061] The embodiment of the present invention also provides a device for realizing the meeting backup function, including a memory and a processor, and the processor implements the following steps when executing the program or instructions stored in the memory:

[0062] Using the first network port of the conference terminal to access the first network for video conferencing, and detecting the status of the first network in real time;

[0063] If it is detected that the first network is abnormal, the conference terminal performs network port switching, and uses the second network port of the conference terminal to access the second network to continue the video conference.

[0064] Further, the processor can also implement the following steps:

[0065] During the conference backup period, the picture of the video conference is kept frozen by performing link keep-alive with the opposite end.

Abstract

The invention discloses a method and a device for implementing a conference backup function, and relates to the field of video conference communication. The method comprises: setting a first network port for accessing a first network and a second network port for accessing a second network on a conference terminal, the first network port and the second network port back up each other; when the conference terminal accesses the first network for a video conference by using the first network port, detecting the state of the first network in real time; if the first network is detected to be abnormal, switching the network port for the conference terminal, and accessing the second network by using the second network port to continue the video conference. The conference is quickly recovered without increasing conference hardware equipment, increasing the network bandwidth, interrupting the conference or seriously damaging the quality of conference images, the screen freeze time is less than1 second, the sound-image quality of the conference is guaranteed, and the cost of operation and maintenance protection is greatly reduced for users.
