Abstract

The invention provides a multimedia service exception protection method and device. The method is applied to a multimedia network, the multimedia network at least comprises a server and a terminal incommunication connection with the server, and the server comprises a media layer. The method comprises the steps that the media layer obtains the channel state of a data channel between the terminal and the media layer, and the channel state at least comprises a normal state and a fault state. When the channel state is a fault state, the media layer counts the duration of the fault state and judges whether the duration is greater than preset time or not; and if the judgment result is yes, the media layer acquires position information of the failed data channel, and deletes the data channel according to the position information. According to the protection method provided by the invention, even if the multimedia network fails and cannot send the instruction of deleting the data channel, thedata channel can still be deleted by acquiring the position information of the failed data channel, the data channel is released in time, and the resource utilization rate of the data channel is improved.

Description

technical field [0001] The invention relates to the technical field of media transmission, in particular to a method and device for protecting multimedia services from anomalies. Background technique [0002] With the development of communication technology, the next-generation network and the Internet Protocol (IP) multimedia subsystem technology for interconnection between networks have been widely used, and multimedia sessions have become very common. Multimedia sessions refer to the transmission of voice, Data services such as video. [0003] In order to support multimedia applications on IP networks, the International Telecommunication Union has formulated H.323 and H.248 protocol standards, and the Internet Engineering Task Force has successively formulated protocol standards such as session initialization protocol and media gateway control protocol. These agreements form a complete multimedia communication system together with other agreements of the IP layer. These...
