Embodiment Construction

[0056] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0057] Firstly, the protocol used in the embodiment of the present invention is briefly introduced as follows.

[0058] The H.248 protocol is defined by the ITU-T SG16 standard organization and is specially used for media resource control. Parameters with business relevance can be logically aggregated into a package (Package), which is a method for extending protocol functions provided by the H.248 protocol. The H.248 protocol expands the functions of the protocol through packets, and adds new functions to the protocol. Generally, it is not necessary to modify the protocol body, but only to define new packets. A package can be regarded as an encapsulation of an independent feature. When a media processing device claims to support this package, it means that it supports this feature, and the media control device can use the at...

Abstract

The embodiment of the invention relates to method and system for improving multi-media connection quality and media control and processing equipment. In the invention, through comparing the parametersof a quality information feedback with corresponding parameters in a present session, the media control equipment notifies a transcoding machine of the media processing equipment to dynamically regulate media data; or through trigging the negotiation between the media control equipment and a multi-media terminal, the media data is regulated dynamically; or through expanding a H.248 indicative massage of the media control equipment, the media processing equipment is ordered to send a quality expansion message to dynamically regulate the media data so as to improve the multi-media connection quality; moreover, the media processing equipment can be used to dynamically detect the quality of the media data transmitted from a media data sending side in the process of the coding and decoding andtransmission of the media data, and to notify the media control equipment of the quality problems when the quality decreases, and then the media control equipment interacts with the media data sending side so as to regulate the media data sent by the media data sending side.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for improving the quality of multimedia calls, media control equipment and media processing equipment. Background technique [0002] A multimedia communication system refers to a network system that can provide multimedia sessions, such as audio and video communications. Currently there are many multimedia communication systems, including H.324 networks using H.324, H.245, H.223 and other protocols; H.323, H.225.0, H.245, Real-time Transport Protocol (Real-time Transport Protocol , hereinafter referred to as RTP) / Real-time Transport Control Protocol (Real-time Transport Control Protocol, hereinafter referred to as RTCP) and other protocols of the H.323 network; using Session Initiation Protocol (Session Initiation Protocol, hereinafter referred to as SIP), Session Description Protocol (SessionDescription Protocol, IP Multimedia Subsystem (IP Mult...
