Fig. 3 is a kind of flow chart of the voice channel method for building up shown according to another exemplary embodiment, such as Fig. 3 institutes Show, which is applied in the first client 10 in the implementation environment shown in Fig. 1, comprises the following steps.

In step 301, receive dial called number dial instruction after, choose the first media engine.

In step 302, the first voice communication request is packaged according to the first agreement using the first media engine, the Called number is included in one voice communication request.

In step 303, the first voice communication request after encapsulation is sent to transfer server.

In step 304, the voice channel being used to establish between the second client that transfer server is sent is received Notice, establishes the voice channel between the second client.

In a kind of possible implementation, the first client is established voice with the second client by transfer server and is led to During road, it may refer to as shown in Figure 4 A, it is a kind of voice channel method for building up according to another exemplary embodiment Flow chart, as shown in Figure 4 A, the voice channel method for building up may include steps of：

Step 401, the first client receive dial called number dial instruction after, choose the first media engine.

When the first client receives after dialing request of user, determine to send the first media of information to transfer server Engine.

In a kind of possible implementation, the step 401 in Fig. 4 A can further be replaced with to step 401a to step Rapid 401b.Refer to shown in Fig. 4 B, it is the flow chart of the first media engine of selection according to an exemplary embodiment, such as Shown in Fig. 4 B, voice channel method for building up may comprise steps of.

In step 401a, media engine corresponding with each client is obtained, each client and the first client are not Together, each media engine is used for the signaling that will be sent according to protocol encapsulation corresponding with media engine, each media engine limit Audio data packet format during VoP is determined to be used to transmit.

In general, the bottom of the first client can have multiple media engines, each media engine has corresponding Standard agreement, namely each media engine can utilize the information that the packing of corresponding standard agreement will be sent, and will packing Information afterwards is sent to transfer server.

For example, corresponding to the media engine of Michat client, the corresponding protocol encapsulation of Michat can be utilized to send out The signaling sent.

In step 401b, the media engine of time delay minimum is selected from each media engine, media engine is determined For the first media engine.

Time delay minimum means that call connection is easier success, and voice quality is more preferable, therefore can select the matchmaker of time delay minimum Body engine.

Step 402, the first client asks to carry out according to the first agreement using the first media engine to the first voice communication Encapsulation.

The call request for being sent to transfer server is packaged by the first client using the first media engine, encapsulation association Discuss the message tunneling that message is received for transfer server.

Step 403, the first client sends the first voice communication request after encapsulation to transfer server.

Step 404, after transfer server receives the first voice communication request that the first client is sent, inquiry and called number The second online client of code binding.

In practical applications, since the agreement that signaling is transmitted under different account systems is different, in order to realize not With voice communication is carried out between the client under account system, transfer can be carried out using transfer server.In order to connect Client under two kinds of agreements, the disclosure make use of middle account, i.e. telephone number, to realize the docking of two clients.

In this case, transfer server can prestore the client of each telephone number binding.As the first client End preparation is when dialing called number, and transfer server can then inquire about the second client corresponding with the called number, and can be with Obtain client online in these second clients.

In a kind of possible implementation, the step 404 in Fig. 4 can further be replaced with to step 404a to step 404b.Fig. 4 C are referred to, it is the second online visitor of the inquiry according to an exemplary embodiment and called number binding The flow chart at family end, as shown in Figure 4 C, voice channel method for building up may comprise steps of.

In step 404a, inquiry with called number binding each second client and each second client Wire state, the presence of the second client are provided by server corresponding with the second client.

Transfer server is inquired about with whether each second client of called number binding is online or empty in call successively Not busy state, when the second client being queried is in offline or call engaged condition, then it is assumed that the client is not in idle shape State (namely not possessing call condition), then inquires about next the second client with called number binding.

Here the second client said can be the client on the mobile terminals such as mobile phone, computer, tablet, this A little clients have usually been logged in by user account, and each embodiment of the disclosure does not limit the species of the second client It is fixed.

In general, when transfer server establish from predetermined third-party server it is this by under different account systems During the business that client is docked, transfer server can be respectively to bound in each third-party server enquiring telephone number Each second client presence, third-party server can then feed back the second client under account number system Wire state.

When actually realizing, transfer server obtains the presence of the second client bound in each telephone number When, it may include steps of：

First, transfer server is inquired about with called number binding and taken with third party for each third-party server Corresponding each second client of business device.

Second, transfer server sends the presence for the mark for including each second client to third-party server Obtain request.

Transfer server is sent to different third-party server The no instruction in networking state.

3rd, transfer server receives the presence for each second client that third-party server is replied.

For example, when some called number is bundled with the second client that Michat number is 123456, at this time, transfer service Device can be then the online of 123456 the second client to third-party server acquisition request corresponding with the Michat Michat number State, third-party server can then be fed back to transfer server the Michat number be 123456 the second client in wire State.

Obviously, after the presence for the second client being requested changes, third-party server can be automatic The presence of changed second client of these presences is reported to transfer server.

In step 404b, second client is determined from current the second online client.

If current the second online client has two or more, transfer server can randomly choose one Second client of line, alternatively, being screened to the networking state of the second client, prioritizing selection is in Wi-Fi networking states Under the second client, alternatively, networking time delay that can also be to the second client counts, prioritizing selection networking time delay is minimum The second client.

If the second client is in networking state with third-party server, which replys transfer service The presence of the second client of device, wherein presence can be including idle, busy etc., if the second client and third party Server is in suspension state, then the third-party server does not reply the inquiry instruction of transfer server transmission.

Step 405, transfer server determines the second media engine of third-party server corresponding with the second client.

After the second online client is determined, then third party's clothes corresponding with second client can be determined Second media engine of business device,

Step 406, transfer server encapsulates the second voice communication according to the second protocol corresponding to the second media engine and asks Ask.

Second protocol of the transfer server according to corresponding to the second media engine, encapsulation the second voice communication request.

Wherein, the mark of the second client is included in second voice communication request, second voice communication request is used for Triggering third-party server notifies the second client there are call request, to receive the confirmation for allowing call that the second client returns Signaling.

Step 407, transfer server sends the second voice communication request after encapsulation to third-party server.

That is, being realized by above-mentioned steps 404 to step 406 will be asked using the first voice communication of the first protocol encapsulation Conversion is asked in order to be provided to third party using the second voice communication request of second protocol encapsulation, second voice communication request Server is identified, and the called number conversion that the first client wants to be conversed is online in order to be bound with the called number The second client.

Step 408, third-party server notifies the second client to there is call after the second voice communication request is received Request.

Third-party server notifies that the mode of the second client can be initiated jingle bell, voice prompt, initiate vibrations etc., this Place notifies third-party server the mode of the second client not limit.

Step 409, third-party server receives the confirmation signaling for allowing call that the second client returns.

When the user of the second client determines to allow call, the second client can then be returned to third-party server to be allowed The confirmation signaling of call, corresponding, third-party server can then receive the confirmation signaling of the second client return.

Step 410, third-party server feeds back the second client to transfer server allows the confirmation signaling of call.

Step 411, the confirmation signaling that transfer server is returned in the second client for receiving third-party server feedback Afterwards, sent to the first client and be used for the notice for indicating the voice channel that the first client is established between the second client, led to The information of the second media engine corresponding with third-party server is carried in knowing.

That is, by above-mentioned steps 408 to step 411, then can realize：Allow to answer the call in the second client When, sending allows confirmation signaling to third-party server, the third party's service of call to send the confirmation signaling to transfer take again Business device, protocol conversion is carried out by transfer server, and the voice channel for notifying the first client to establish between the second client.

Step 412, the first client receives the voice being used between foundation and the second client that transfer server is sent The notice of passage, establishes the voice channel between the second client.

First client receives transfer server and sends the notice for establishing the voice channel between the second client, then Voice channel is established according to the audio data packet format corresponding to the second media engine, carrying out voice with the second client is connected.

In a kind of possible implementation, the step 412 in Fig. 4 A can further be replaced with to step 412a to step Rapid 412c.Refer to shown in Fig. 4 D, it is the voice between foundation and the second client according to an exemplary embodiment The flow chart of passage, as shown in Figure 4 D, voice channel method for building up may comprise steps of.

In step 412a, the audio data packet format that the first media engine limits is obtained.

In step 412b, if the language that audio data packet format and the second media engine that the first media engine limits limit Sound data packet format is identical, then VoP is sent to third-party server, to trigger third-party server by voice data Bag is sent to the second client, opens the voice channel between the first client and the second client.

First client is contrasted the first media engine of acquisition and the second media engine, if the first media engine The audio data packet format of restriction is identical with the audio data packet format that the second media engine limits, it is meant that the first media engine It is same media engine with the second media engine, can be direct after the first client carries out protocol conversion according to the first media engine VoP is sent to the 3rd server, voice channel is established by the 3rd server and the second client, is conversed.

In step 412c, if the language that audio data packet format and the second media engine that the first media engine limits limit Sound data packet format is different, then sends VoP to transfer server, be converted into VoP by transfer server The form that third-party server can identify, and transformed VoP is sent to third-party server, to trigger Tripartite's server sends VoP to the second client, and the voice opened between the first client and the second client leads to Road.

If the VoP lattice that audio data packet format and the second media engine that the first media engine limits limit Formula is different, it is meant that the first media engine and the second media engine are not same media engines, and the first client is according to the first matchmaker After body engine carries out protocol conversion, also need to carry out the second media engine protocol conversion, concurrent sending voice data packet to transfer takes It is engaged in device, VoP is converted into the form that third-party server can identify by transfer server, then take by third party Business device and the second client establish voice channel, converse.

Above-mentioned steps 401 to step 403 and step 412 can be individually implemented as using the first client as executive agent Voice channel method for building up, step 404 to step 407 and step 411 can be individually implemented as using transfer server as execution The voice channel method for building up of main body.

In addition, transfer server is come true by inquiring about the presence of the second client corresponding to third-party server Fixed second media engine, and the second media engine information is sent to the first client, notify the first client to establish voice channel； First client sends call request using the first media engine to transfer server, by the first media engine of acquisition and second Media engine is contrasted, if the two is identical, VoP is sent directly to third-party server, if different VoP is sent to transfer server and carries out protocol conversion, realizes that voice connects.
