Media conversion equipment control method, device and media gateway

Abstract

Embodiments of the present invention provide a media conversion device control method, device, and media gateway. By acquiring the first media data sent by the first user terminal to the second user device through the media conversion device, it is determined whether the media conversion device needs to work in the conversion mode. In transcoding mode, when it is determined that the encoding method adopted by the first user terminal is not compatible with the second user terminal, control the media conversion device to work in transcoding mode. In this scheme, the scheme of controlling the working mode of the media conversion device through the media data on the media plane is compared to the scheme of controlling the working mode of the media conversion device after generating a control message according to the SDP information on the control plane, and the interruption lasts for several seconds to more than ten seconds The solution can shorten the duration of call interruption to a large extent, achieve the effect of quick call recovery, ensure the quality of service provided by the operator, and guarantee the user experience and the interests of the operator.

Description

technical field [0001] The invention relates to the communication field, in particular to a media conversion device control method, device and media gateway. Background technique [0002] When a terminal needs to communicate with another terminal, the two terminals will collect the sound signal in the environment where they are located during the call, and encode the collected sound information to form media data. For the two For a terminal that conducts a video call, what participates in encoding also includes image information collected by the terminal. Before the call is established, the two parties in the call will negotiate through the call control network which encoding method they should use to encode the media data. The following combines figure 1 The networking diagram and figure 2 The interaction diagram shown briefly explains the process of establishing a call between two terminals: [0003] S201. The second terminal 15 initiates a call request. [0004] The ...

Although this control method will shorten the call interruption time between the first terminal 11 and the second terminal 15, and advance the time for resuming the normal call, generally speaking, the media gateway is controlled to switch the working mode by sending a control message through the control plane. The method is still relatively slow, and the call will still be interrupted for a period of time

[0014] Therefore, the above two methods will cause the call to be interrupted for a period of time. Although the interruption time of the two is only between a few seconds and a dozen seconds, for the user, this will not only bring inconvenience to it, but may even cause Huge loss, because during this period of time, users may need to communicate or receive important information from the peer end; in addition, a large number of users are forced to interrupt the call due to this situation, resulting in low user experience, which may cause large Complaints from users in the area are a kind of damage to the interests of operators and service quality
