A method for processing a media data packet, comprising: receiving, by a conference floor server CFS, a virtual public participant VPP channel establishment request sent by a conference proxy server CPS, wherein the VPP channel establishment request comprises a conference identity and a conference member identity corresponding to the conference identity; and establishing, with the CPS, according to the VPP channel establishment request, a VPP channel corresponding to the conference identity; acquiring, by the CFS, a media data packet corresponding to each conference member identity, and when there are media data packets with same content in the media data packet corresponding to each conference member identity, acquiring a media data packet with a highest frequency of same content among the media data packets as a public media data packet, and forwarding the public media data packet to the CPS through the VPP channel; and acquiring, by the CFS, from conference member identities corresponding to the public media data packet, a conference member identity that currently does not multiplex the VPP channel, generating, by the CFS, a real-time transport control protocol RTCP multiplexing start command corresponding to the conference member identity that currently does not multiplex the VPP channel, and delivering the RTCP multiplexing start command to the CPS, so that the CPS starts, according to the RTCP multiplexing start command, to forward, through a real-time transport protocol, RTP, channel between the CPS and a user equipment corresponding to the conference member identity that currently does not multiplex the VPP channel, the public media data packet on the VPP channel to the user equipment corresponding to the conference member identity that currently does not multiplex the VPP channel. receiving, by a conference floor server CFS, a virtual public participant VPP channel establishment request sent by a conference proxy server CPS, wherein the VPP channel establishment request comprises a conference identity and a conference member identity corresponding to the conference identity; and establishing, with the CPS, according to the VPP channel establishment request, a VPP channel corresponding to the conference identity; acquiring, by the CFS, a media data packet corresponding to each conference member identity, and when there are media data packets with same content in the media data packet corresponding to each conference member identity, acquiring a media data packet with a highest frequency of same content among the media data packets as a public media data packet, and forwarding the public media data packet to the CPS through the VPP channel; and acquiring, by the CFS, from conference member identities corresponding to the public media data packet, a conference member identity that currently does not multiplex the VPP channel, generating, by the CFS, a real-time transport control protocol RTCP multiplexing start command corresponding to the conference member identity that currently does not multiplex the VPP channel, and delivering the RTCP multiplexing start command to the CPS, so that the CPS starts, according to the RTCP multiplexing start command, to forward, through a real-time transport protocol, RTP, channel between the CPS and a user equipment corresponding to the conference member identity that currently does not multiplex the VPP channel, the public media data packet on the VPP channel to the user equipment corresponding to the conference member identity that currently does not multiplex the VPP channel.
