Audio/video communication in the embodiment of the present invention, only can comprise voice communication, as the call between PC terminal use and cellphone subscriber, also only can comprise video communication, or comprise the communication of Voice & Video simultaneously.
The PC terminal provided the embodiment of the present invention two below and the audio/video communication method of mobile phone are described.
For ease of the technical scheme of the embodiment of the present invention is described, be described for the technical program embody rule scene.See Fig. 2, show the schematic network structure of a technical program application scenarios, this network configuration comprises signaling Control Server (RealTimeMediaController, RTMC) telecommunications gateway 26, gateway exchange 27 and mobile phone 22 in the PC terminal 21 24, in media transfer server (MediaTransferGateway, MTG) 25, the Internet and certification access server 23, telecommunications network.Wherein, in scene shown in Fig. 2, signaling Control Server and media transfer server are arranged on the region joined between the Internet and telecommunications network, be appreciated that, one in signaling Control Server and media transfer server also can be arranged in the Internet or telecommunications network, or signaling Control Server and media transfer server also can be arranged in the Internet or be arranged in telecommunications network simultaneously simultaneously.
Fig. 3 shows the audio/video communication method flow schematic diagram of PC terminal that the embodiment of the present invention two provides and mobile phone.Specifically comprise following process:
1:PC terminal is established to the encryption connection of certification access server.
In order to ensure the safety communicated, and, ensure to provide corresponding service etc. to legal authorized user, be provided with certification access server in a network, encryption connection between this certification access server and PC terminal, in order to when PC accessing terminal to network, carries out authentication to PC terminal.In the occasion that network security requirements is lower, also can not adopt above-mentioned certification access server, directly invitation signaling is sent to signaling Control Server by PC terminal.
Authentication information is sent to certification access server by 2:PC terminal.
Self proprietary authentication information is sent to certification access server by described encryption connection by PC terminal.
3: authentication success message is fed back to PC terminal by certification access server.
The authentication information of certification access server to PC terminal is verified, if by checking, sends authentication success message to PC terminal; If authentication failed, send authentication failure message and process ends to PC terminal.Because the situation of authentication failed associates less with the technical program, mainly situation when being proved to be successful is described in the present embodiment.
Invitation signaling is sent to certification access server by 4: after authentication success, PC terminals.
PC terminal comprises the phone number of invited party's (as being invited to mobile phone) to invitation (Invite) signaling that certification access server sends, with the mobile phone of will signaling be invited to be sent to the communication of expectation according to this phone number.
The invitation signaling that the embodiment of the present invention adopts is Session initiation Protocol (SessionInitiationProtocol, SIP) signaling is invited, this SIP invites signaling to use Session Description Protocol (SessionDescriptionProtocol, SDP) signaling body, described SDP signaling body at least comprises following content:
Conversation media type, the network address of invited party, the media coding format supported and code check.
Above-mentioned conversation media type indicates that this audio/video communication is video (Video) type, audio frequency (Audio) type or simultaneously relate to Voice & Video type;
The network address of network address instruction communication originating end (PC terminal) of above-mentioned invited party;
The media coding format that above-mentioned supported media coding format and code check indicate the originating end (PC terminal) that communicates to use and code check.
Show the example of a kind of SDP signaling body that the embodiment of the present invention provides below.
5: invitation signaling is forwarded to signaling Control Server by certification access server.
Because signaling Control Server needs to carry out data interaction with the equipment in the Internet and telecommunications network respectively, so require signaling Control Server at least to have the first network interface card function and the second network interface card function, described first network interface card function supports the communication with internet device, and described second network interface card function supports the communication with telecommunication apparatus.
In above-mentioned steps, believable signaling Control Server receives the invitation signaling of certification access server forwarding by the first network interface card function.
When not arranging certification access server in network, believable signaling Control Server directly receives the invitation signaling of PC terminal transmission by the first network interface card function.
