Embodiment

[0027] According to the codec-encrypted media gateway method of the present invention, the number of fixed thread pools is set according to the number of session codecs supported by the communication protocol, and when media negotiation occurs, idle threads are started according to the codec information in the SDP carried in the SIP message , schedule system resources, complete encrypted transmission of codec resources, and encrypt and decrypt media information carried in media negotiation during encryption.

[0028] The maximum number of thread pools in the fixed thread pool is configured according to the encoding information in the SDP carried in the current SIP message.

[0029] After the media gateway system is started, configure the maximum number of idle threads supported by the current media gateway system according to the number of codecs supported by the media gateway to which the current user belongs, start and create an idle business processing thread pool, and creat...

Abstract

The invention discloses a method and system for encrypting a media gateway based on codec, which belong to the technical field of communication. According to the method of encrypting a media gateway based on codec, based on a session codec amount supported by a communication protocol, the number of fixed thread pools is set; when media negotiation occurs, based on the codec information in SDP carried in an SIP message, an idle thread is started, system resources are scheduled, and encrypted transmission on the codec resources is completed; and in the case of encryption, the media information carried in media negotiation is encrypted and decrypted. According to the method of encrypting a media gateway based on codec, a media negotiation data packet can be prevented against monitoring, eavesdropping, tampering, identity forging and denial of service, the security of media negotiation in the user session process is thus ensured, and the popularization and application value is good.

Description

technical field [0001] The invention relates to the technical field of communication, and specifically provides a method and system for a codec-based encrypted media gateway. Background technique [0002] In the IMS domain, under the C5 architecture, signaling and bearer are separated. The IMS service processing network element is responsible for signaling analysis, service triggering, signaling control and other functions, and the bearer is carried by the network element MGW (Media Gateway). Completed, when the session is initiated, when it is necessary to play the sound or make a call, it is necessary to conduct media negotiation on the codecs supported by the calling and called sides to complete the normal connection of the session. In addition, in the IMS domain, the diversity of end users makes it difficult for end users to control the peer network, and loses controllability over network services, voice quality, and security mechanisms. The setting lacks a unified mana...
