Abstract:
1. A method for cross-platform conference convergence which is applied to a conference system comprising a gateway device, a first application server (AS), a first media resource server (MRS) on a side of the first AS, a second AS and a second MRS on a side of the second AS, comprising: receiving, by the gateway device, an INVITE request sent by the first AS after the first AS acknowledging the gateway device has joined a first conference created by the first MRS, wherein the INVITE request is a request for inviting a second terminal to attend the first conference and the second terminal is served by the second AS; sending, by the gateway device, an invitation call for creating a second conference to the second AS, to enable the second AS to instruct the second MRS to create the second conference, wherein the invitation call comprises parameters that are negotiated by the gateway device with the first MRS and are used for transmitting a media stream between the first MRS and the gateway device; and after the gateway device receives conference creation success information sent by the second AS, sending by the gateway device an invitation to the second AS to invite the second terminal to attend the second conference, and acquiring, by the gateway device, transmission-related parameters from the second MRS through the second AS, wherein the transmission-related parameters are determined by the second MRS according to intersection between the parameters carried in the invitation call and parameters supported by the second MRS and used for transmitting a media stream between the second MRS and the gateway device; receiving, by the gateway device, a first media stream of the first conference sent by the first MRS, and forwarding the first media stream to the second MRS to play the first media stream to the second terminal that has joined the second conference; and receiving, by the gateway device, a second media stream of the second conference sent by the second MRS, and forwarding the second media stream to the first MRS to play the second media stream to a participant of the first conference.
