Problems solved by technology

For example, if the user's voice communication fails, the user is still charged, resulting in a bad user experience.
[0005]The signaling level cannot make timely adjustments for the better according to the information reported by the media level
It is impossible to switch new users to a new link with good QOS quality in a timely manner when the QOS quality of a media link is degraded, packet loss, or congestion, so that the quality of multimedia communication cannot be improved in real time
[0006] Existing router technologies such as BFD (Bidirectional Forwarding Detection) and OAM (operation management and maintenance) can detect link QOS quality, but these technologies cannot distinguish multimedia A certain call of a certain user in the communication cannot inform the signaling layer that a certain media stream is abnormal
Therefore, the signaling layer cannot make a better response to some users' calls
In addition, this technology needs to be supported by all devices on the network. If there is a device that does not support it, it cannot be detected.

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, it is a schematic structural diagram of an embodiment of a system in which the media plane controls the signaling plane in the present invention; the system includes: a media plane entity 1 and a signaling plane entity 2 . in,

[0023] The media plane entity 1 is used to detect abnormal information of the session, and report the detected abnormal information to the signaling plane entity 2, wherein the abnormal information of the session includes QoS quality abnormal information and / or media abnormal information;

[0024] The signaling plane entity 2 is configured to determine a processing policy corresponding to the received abnormal information according to pre-configuration, and process the session in which the abnormal inform...

Abstract

An embodiment of the invention discloses a method of a medium plane to control a signalling plane, comprising: detecting conversational abnormal information by a medium plane entity; reporting the abnormal information to a signalling plane entity; determining process strategy corresponding to the received abnormal information according to preset configuration by the signalling plane entity; processing the conversation of the abnormal information through determined process strategy by the signalling plane entity. The embodiment of the invention detects conversational QoS quality and / or medium abnormal information on the medium plane entity, informs to the signalling plane entity, therefore, the signalling plane entity adopts the strategy corresponding to the conversational QoS quality and / or medium abnormal information through adjusting the signalling, to improve communication quality.

Description

technical field [0001] The invention relates to a media transmission network, in particular to a method and a system for controlling a signaling plane by a media plane. Background technique [0002] With the development of communication technology, NGN-Next Generation Network (NGN) and IP Multimedia Subsystem (IMS-IP Multimedia Subsystem, IMS) technologies have been widely used, and voice, image, video and data are all transmitted through the Internet. Protocol (Internet Protocol, IP) to carry, has become a major trend. In order to support multimedia applications on IP networks, the International Telecommunication Union (ITU-T) formulated the H.323 and H.248 protocol standards, and the Internet Engineering Task Force (IETF) successively formulated the Session Initiation Protocol (SIP) ), Media Gateway Control Protocol (Media Gateway Control Protocol, MGCP) and other protocol standards. These agreements form a complete multimedia communication system together with other agr...
