The embodiment of the present invention provides a kind of method established based on Web RTC multi-party call, as shown in Fig. 2, this method packet
It includes:
In the initial phase of the present embodiment, the first user carries out two side's calls with third user, but the first user needs
Multi-party call is established, newly-increased user is second user.
101, the first user sends multi-party call to conference applications server and establishes request.It include the first extension in the request
Message, described first extends the information for establishing the second user of multi-party call in message up for the first user.
Above-mentioned multi-party call includes at least the transmission of audio stream and video flowing.Further, when above-mentioned multi-party call is base
When Session initiation Protocol (Session Initiation Protocol, SIP), the first extension message, described second are expanded
Open up message, third extension message is the extension message based on the SIP.
Specifically, passing through the XML redefined when the signaling protocol in above-mentioned multi-party call is using Session Initiation Protocol
Data format extends Message message body in Session Initiation Protocol, is carried out using the routing mechanism of Session Initiation Protocol to Message message
Routing, and then realize the information exchange between application server and client.
Illustratively, by taking the first user as an example, client initiates MPTY request to the extension message of application server
It is as follows:
It include sequence number " 4001 ", the title " A " of sender of the message, connection type of the message in above-mentioned message
And the information such as corresponding sessions participant " web RTC---B ", " web---C ".
102, the multi-party call that conference applications server receives that the first user to converse sends establishes request.The request
In include first extension message, it is described first extension message in need the second user that multi-party call is established with first user
Information.
103, conference applications server judges that the first user establishes the permission of multi-party call.
104, when the first user has the permission for establishing multi-party call, application server is established more to the first user transmission
The the second extension message just conversed, and third extension message is sent to the third user to converse with the first user.The third
Extending includes the list information for participating in the multi-party call member in message.
As info class in step 101, application server sends the corresponding message for establishing multi-party call to the first user
It is exemplified below.
Above-mentioned message includes the result res and the multi-party call of the serial number cmd of the message, multi-party call foundation
Serial number id, specifically, the value 4002 of cmd is the message sequence number for the multi-party call established, 0 table of value of res by taking above-mentioned message as an example
Show that the multi-party call is successfully established, the value 0001 of id indicates the serial number 0001 of the multi-party call, if the value of res is not 0,
Show that the multi-party call is failed foundation due to other.
105, conference applications server sends the request that multi-party call is added to second user, includes participating in institute in the request
State the list information of multi-party call member.
The request of the multi-party call is that conference applications server is multi-party with establishing in the promoter that confirmed multi-party call
After the permission of call, the request that Multi-Party Conference is added is sent to the third party for needing to be added multi-party call, and carry multi-party call
The list information of member, in order to which third party carries out the judgement of permission to meeting promoter.
In the present embodiment, conference applications server sends adding by the first Client-initiated multi-party call to second user
Enter request, and further comprise member list information relevant to this multi-party call in addition request, in order to the second use
The necessity that this multi-party call is added in family judges, and is determined whether that the multi-party call is added according to judging result.
106, second user receives the request for the multi-party call that application server is sent, and includes that participation is described more in the request
The list information just conversed.
In the request for the multi-party call for receiving application server transmission, according to the participation multi-party call for including in request
List information judges the necessity of the multi-party call.
107, it is more to send confirmation addition to application server after the correctness for confirming the MPTY request for second user
The information just conversed.
The information expression second user that the confirmation is added is after judging the necessity that the multi-party call is added, certainly
It is fixed to be added by the first Client-initiated multi-party call.
If second user decides not to join the multi-party call after judgement, then refusal is sent to application server and be added
Message.
108, the information that the confirmation that application server receives that second user is sent is added.
109, application server respectively between the first user and second user, establish and be used between third user and second user
The media channel of multi-party call.
Here the media channel established is respectively used to the first user and leads to second user, third user and second user
Words, so that in the multi-party call, have direct point-to-point between any two side is used for transmission audio stream and video flowing
Transmission channel finally makes in entire multi-party call, each with there is the channel being connected with any other user per family, into one
Step, each use per family as a Web RTC client, get user itself including at least audio stream and video
The Media Stream of stream, by the Media Stream after locally being saved, the Media Stream that will acquire can be by being connected with other users
Media channel be sent at other users, to realize multi-party call.
Further, each user i.e. each Web RTC client is receiving other clients by corresponding matchmaker
When the Media Stream that body channel transfer comes,<Audio>label of multiple HTML5 is created on the page of user browser, each
The source Source of label is arranged with the Media Stream of a client, in this way can be simultaneously by multiple<Audio>labels
Multiple Media Streams are played, that is, can hear the sound of multiple client simultaneously in the client；In corresponding Media Stream
The processing method of video flowing is similar, by establishing multiple<Video>labels, so that can play multiple visitors simultaneously in the client
The video image at family end, by the above-mentioned Media Stream for carrying out being multiplexed and handling simultaneously multichannel to Media Stream, to realize multiple pass
Words.
Similar with the message format in step 101 and 104, it is multi-party that conference applications server controls user's access to be added
The Examples of information of call are as follows:
Above- mentioned information include main control side's (also referred to as multi-party call of the serial number cmd of the message, the multi-party call
Chairman) serial number userid and the multi-party call other participants serial number attendee.
Specifically, the value 4003 of cmd is the serial number of the multi-party call by taking above-mentioned message as an example, the value of userID shows for a
The serial number of the main control side (or chairman of the multi-party call) of the multi-party call, the value of attendee are respectively that b, c show that this is more
The serial number of other participants just to converse.
According to foregoing description, as shown in figure 3, the specific steps for establishing media channel include:
1091, the first user sends the message request for establishing media channel to second user.
1092, second user receives the message request for establishing media channel that the first user sends.
1093, second user judges the correctness of message request sender.
It here is list information of the second user according to the participation multi-party call member received in advance from application server,
Judge whether sender's namely correctness of the first user or the first user of message request has initiation multi-party call
Permission.
1094, after second user determines that message request sender is correct, the information for receiving and inviting is replied to the first user, and
Build on the media channel of the first user.
Due to second user it is determined that crossing the permission that message request sender namely the first user initiates multi-party call,
Therefore, second user is after the media channel for building on the first user, then receives after the message of the first user, takes
It is different from the processing mode of normal talking message.
Under normal talking mode, since second user has been in the environment of multi-party call, that is, in logical
Therefore speech phase, then receives after the call request of other users, default is to return to that " you dial to other users
The user beaten is busy now " etc. similar the line is busy information；But currently due to the first user be in second user in advance from
In the information list of the multi-party call member of conference applications server, therefore, for as the first user from multi-party
The call request and call-information, second user that user in the information list of conversation member sends can take session in meeting to ask
Processing mode is sought, i.e., do not pop up dialog box or does not trigger Ring Mode, it is directly automatic to receive call.
Especially in first call after second user and the first user establish media channel, take above-mentioned " quiet
It is silent " processing the advantages of be that second user can be enabled to enter the state for having accessed multi-party call faster, that is, be only
Second user to conference applications processor return be added multi-party call after, be directed to by the first user or other users transmission
The request of media channel is established, extra prompt is no longer carried out, facilitates that second user is enabled to enter multi-party call as soon as possible in this way
State in, avoid second user can receive repeatedly be added multi-party call prompt, to promote the experience of second user.
So far, the information transfer channel between the first user and second user, which has been completely set up, finishes, as before with
First user is carrying out the third user of double-talk, and the mode that it establishes media channel with second user is directed to above-mentioned
The method that first user and second user establish media channel is completely the same, and it is noted that third user here
Establish the time of media channel with second user and the first user and second user establish media channel in time be simultaneously into
Capable, the time for establishing IMS conference medium channel can be saved to the full extent in this way, it is clear in order to state in the present embodiment, therefore
The two is separated and is described, and is illustrated herein.
110, according to method shown in step 1091 to 1094, the first user, third user is sequentially completed and needs to be joined
The foundation of the media channel of the side's of adding calling user, and by established media channel, carry out multi-party call.
The embodiment of the present invention provides a kind of method established based on Web RTC multi-party call, passes through the first user to meeting
Application server sends the request for establishing multi-party call, and conference applications server judges whether the first user establishes multi-party call
Permission, determine the first user have establish the request of multi-party call after, to the user of multi-party call to be participated in send be added
The request of Multi-Party Conference and the member list information for being accompanied with the multi-party call, in order to other users to whether be added it is multi-party logical
Words are judged, after other users send the information of addition Multi-Party Conference to conference applications server, enable the first user Xiang Qi
His user sends the invitation for establishing media channel, and replys in other users and receive the information for establishing media channel, thus success
Establish the media channel of the first user and other users.Eventually by the media channel of foundation, and combine Media Stream multiplexing and
The technology of audio-video label in browser, to realize multi-party call；To setting caused by can reduce as carrying out local audio mixing
The standby higher requirement of performance can also carry out cumbersome meeting-place resource bid without contacting pts server, further save and work as
The waste of meeting-place resource caused by when multi-party call reverts to double-talk, finally reduces the establishment step of multi-party call, mentions
The high service efficiency of the communication resource.
The embodiment of the present invention provides a kind of method established based on Web RTC multi-party call, as shown in figure 4, this method packet
It includes:
The present embodiment is used for two sides that will be being conversed, and is altered to the call form of Three-Way Calling.Due to use scope compared with
It is small, therefore double-talk is only changed to as a upper embodiment special case of multi-party call, also assisted as a kind of based on Web RTC
View, realizes the supplement of multiside calling method.
In the initial phase of the present embodiment, the first user and second user are in call hold mode, while the first user
It is in and is busy now with third user.
201, the first user sends the first information for establishing multi-party call to application server.
Above-mentioned multi-party call includes at least the transmission of audio stream and video flowing.Further, when above-mentioned multi-party call is base
When Session initiation Protocol (Session Initiation Protocol, SIP), the first extension message, described second are expanded
Open up message, third extension message is the extension message based on the SIP.
Specifically, passing through the XML redefined when the signaling protocol in above-mentioned multi-party call is using Session Initiation Protocol
Data format extends Message message body in Session Initiation Protocol, is carried out using the routing mechanism of Session Initiation Protocol to Message message
Routing, and then realize the information exchange between application server and client.
202, application server judges that the first user establishes the permission of multi-party call.
203, after the first user has the permission for establishing multi-party call, application server sends to the first user and successfully builds
The second message of vertical multi-party call.
204, application server sends third message to third user, includes the correlation of second user in the third message
Information and the first user are successfully established the message of multi-party call.
It 205, is " multi-party call " by the Status Change of itself after third user receives third message.
206, application server sends the 4th message to second user, includes the correlation of third user in the 4th message
Information and the first user are successfully established the message of multi-party call.
207, the Status Change of itself is " multi-party call " by second user, and establishes media channel with third user.
208, after second user and third user establish media channel, in conjunction with the first user on call
With third user, multi-party call is realized.
Here the media channel established is respectively used to second user and converses with third user, so that in the multi-party call
In, there is the transmission channel for being used for transmission audio stream and video flowing of direct point-to-point between any two side, finally makes
In entire multi-party call, each with there is the channel being connected with any other user per family, and further, each with making per family
For a WebRTC client, in the Media Stream including at least audio stream and video flowing for getting user itself, by the media
It flows after locally being saved, the Media Stream that will acquire can be sent to other by the media channel being connected with other users
At user, to realize multi-party call.
Further, each user i.e. each Web RTC client is receiving other clients by corresponding matchmaker
When the Media Stream that body channel transfer comes,<Audio>label of multiple HTML5 is created on the page of user browser, each
The source Source of label is arranged with the Media Stream of a client, in this way can be simultaneously by multiple<Audio>labels
Multiple Media Streams are played, that is, can hear the sound of multiple client simultaneously in the client；In corresponding Media Stream
The processing method of video flowing is similar, by establishing multiple<Video>labels, so that can play multiple visitors simultaneously in the client
The video image at family end, by the above-mentioned Media Stream for carrying out being multiplexed and handling simultaneously multichannel to Media Stream, to realize multiple pass
Words.
In step 207, as described in Figure 5, second user is established media channel with third user and is specifically included:
2071, second user restores the talking state with the first user, and establishes media channel to application server transmission
Message request, include the property parameters of second user in the message request.
2072, application server judges that the invitation message for the call request in multi-party call, is not triggering supplement industry
Under the premise of business, the message request is forwarded to third user.
2073, third user is multi-party logical according to the state of fixed " multi-party call ", and in conjunction with the invitation message
Call request in words sends the 5th message to application server, and the 5th message includes the property parameters of third user.
2074, the 5th message is sent to second user by application server, is successfully established second user and third user's
Media channel.
Since third user is on call with the first user, in step 2072, application server to
Before third user forwards the message request, the sender to the message request is needed to judge.
Under normal talking mode, due to third, user has been in the environment of multi-party call, that is, in logical
Therefore speech phase, then receives after the information of other users, default will return to that " you are dialed to other users
