The inventive method embodiment one

A kind of communication means comprising voice data is provided, mainly can apply to as seen in figure la and lb Comprising the communication system of voice data, system as shown in Figure 1a includes the sub-meeting-place of multiple audio frequency and audio mixing Equipment, includes multiple client in the sub-meeting-place of each audio frequency, some client in these multiple clients (the such as first client) can be as main body machine, other client in main body machine meeting-place sub-with this audio frequency respectively End is communicatively coupled, and audio mixing equipment is communicatively coupled with these multiple clients respectively and (does not shows in Fig. 1 a Go out the communication connection between audio mixing equipment and nonbody machine).Wherein:

Client can add the sub-meeting-place of a certain audio frequency, and between other client, foundation comprises voice data Communication session and carry out, with other client, the communication that comprises voice data, wherein comprise voice data Communication can be the communication of pure audio data, or the communication etc. of video data.Client is mainly used in right It is picked up apart from a range of sound of this client, and pickup signal is sent to audio mixing equipment enters Row audio mixing；Client as main body machine is additionally operable to receive the audio signal that audio mixing equipment sends, and will connect The audio signal received is sent to other client in the sub-meeting-place of affiliated audio frequency and plays out.The embodiment of the present invention In client can be the visitor of the voice communication loaded in portable terminal (such as mobile phone or pad etc.) Family end.

Audio mixing equipment meeting-place sub-with each audio frequency respectively is connected, and is mainly used in receiving the sub-meeting-place of each audio frequency Audio signal, and re-send to the main body in the sub-meeting-place of each audio frequency after the audio signal received is carried out audio mixing Machine, main body machine other client that the audio signal of reception is sent to the sub-meeting-place of affiliated audio frequency is broadcast Put.

System as shown in Figure 1 b includes two sub-meeting-place of audio frequency (the i.e. first sub-meeting-place of audio frequency and the second sound The most sub-meeting-place), the sub-meeting-place of each audio frequency includes multiple client, some client (ratio in multiple clients Such as the first client) can communicate between the main body machine in the sub-meeting-place of two of which audio frequency as main body machine Connect.After any body machine can carry out audio mixing to the audio signal in the sub-meeting-place of audio frequency belonging to this main body machine It is sent to the main body machine in the sub-meeting-place of another audio frequency.

The method of the present embodiment is by the sub-meeting-place of audio frequency a certain in system (the such as first sub-meeting-place of audio frequency) As the method performed by the first client of main body machine, flow chart is as in figure 2 it is shown, include:

Step 101, sets up and the first communication link between other client in the sub-meeting-place of the first audio frequency respectively.

It is appreciated that user can operate the first client so that this first client joins a certain sound In the most sub-meeting-place (the such as first sub-meeting-place of audio frequency), such as can pass through " shaking ", or " face-to-face Build group " user operation instruction so that other in the first client-side search to a range of space The client of voice communication, and together join the first sub-meeting-place of audio frequency with the client of other voice communication In.In the present embodiment, add the multiple clients in the sub-meeting-place of same audio frequency and be mainly in certain limit The interior client in space, the client in such as one room, or a certain wireless network coverage Interior client.

After multiple clients join the first sub-meeting-place of audio frequency, need to determine one in these multiple clients Individual client (the such as first client) is as main body machine, then other client is nonbody machine.In reality In the application of border, when determining the main body machine in the sub-meeting-place of a certain audio frequency, can be set by audio mixing equipment or third party Come really for the network delay average arriving other client according to each client in a sub-meeting-place of audio frequency respectively Fixed.Specifically determine that the process of main body machine can have a following two ways:

(1) in the case of as shown in Figure 1a, after multiple clients join the first sub-meeting-place of audio frequency, Multiple clients just and are communicatively coupled between audio mixing equipment, can select one by audio mixing equipment Main body machine.

With reference to shown in Fig. 3 a, in this case, for the first client, performing following step After rapid A1 to A3, the first client can be triggered and start to perform the flow process of step 101 to 104:

Step A1, obtains the network delay of other client in the first client to the first sub-meeting-place of audio frequency equal Value.

First client can be completed by PING mode to the network delay value of another client, and i.e. first Client sends network Internet Control Message Protocol (Internet Control Messages to another client Protocol, ICMP) echo request, meeting after another client receives ICMP echo request Auto-returned ICMP return response message, will send ICMP request bag and receives between ICMP response bag Time interval is as the networking time delay value of this first client to another client, the net of this first client Network time delay average is that the first client is respectively to the network delay value of other client in the first sub-meeting-place of audio frequency Meansigma methods.

Step A2, is sent to comprise the communication system of voice data by the network delay average of the first client In audio mixing equipment, such audio mixing equipment other client in obtaining the first sub-meeting-place of audio frequency is corresponding After network delay average, choose client corresponding to wherein minimum network delay average (the such as first visitor Family end) as main body machine, in the sub-meeting-place of network delay average ratio the first audio frequency of the i.e. first client other The network delay average of client is the least, then audio mixing equipment can send announcement information to the first client.

Step A3, receives the announcement information that audio mixing equipment sends, and this announcement information includes that the first client is made It is the information of the main body machine in the first sub-meeting-place of audio frequency.

(2) in the case of as shown in Figure 1 b, after multiple clients join the first sub-meeting-place of audio frequency, A main body machine can be selected by the third party device being all connected with multiple clients respectively.3rd Method, apparatus can be the management equipment etc. in system for multiple clients.

With reference to shown in Fig. 3 b, in this case, for the first client, performing following step After rapid B1 to B3, the first client can be triggered and start to perform the flow process of step 101 to 104:

Step B1, obtains the network delay of other client in the first client to the first sub-meeting-place of audio frequency equal Value.

Step B2, is sent to third party device, such third party by the network delay average of the first client After the equipment network delay average that other client is corresponding in obtaining the first sub-meeting-place of audio frequency, choose it Client (the such as first client) corresponding to the network delay average of middle minimum is as main body machine, concurrently Send announcement information to the first client.

Step B3, receives the announcement information that third party device sends, and this announcement information includes the first client Information as the main body machine in the first sub-meeting-place of audio frequency.

So, after determining main body machine by said method, the main body machine in the sub-meeting-place of arbitrary audio frequency is to this sound The standard deviation of the network delay of other client in the most sub-meeting-place is minimum.

Step 102, receives the first audio signal, and this first audio signal is outside the first sub-meeting-place of audio frequency The audio signal of the audio signal in the sub-meeting-place of other audio frequency.

In the case of the one such as Fig. 1 a, the audio signal in audio mixing equipment meeting-place sub-to each audio frequency carry out Audio mixing, the first client is to receive the first audio signal that audio mixing equipment sends.As shown in Figure 1 b In the case of Zhong, the audio signal in the meeting-place sub-to affiliated audio frequency of the main body machine in the sub-meeting-place of each audio frequency carry out Audio mixing, the first client is to receive the first audio signal that the main body machine in the second sub-meeting-place of audio frequency sends.

Step 103, the first audio signal is sent respectively to by the first communication link set up by step 101 Other client in the first sub-meeting-place of audio frequency plays out.

Step 104, plays the first audio signal after the preset time delay after receiving the first audio signal, Preset time delay is the network delay average to other client.

Owing to the first client is to need certain network when sending the first audio signal to other client Time delay, then the first client is play first after receiving the certain time after the first audio signal again and is mixed During tone signal, it is only possible to so that in the first sub-meeting-place of audio frequency, all client synchronization play this first audio mixing letter Number.Wherein certain time is network delay average, and the specially first client transmits a signal to first respectively The average of time, i.e. network delay average used by other client in the sub-meeting-place of audio frequency.

It should be noted that ordering relation the most absolute between above-mentioned steps 103 and 104, Ke Yitong Shi Zhihang, it is also possible to order performs, the simply one of which concrete implementation mode shown in Fig. 2.

Visible, in the method for the present embodiment, arbitrary audio frequency meeting in the communication system comprise voice data Main body machine (first client in the such as first sub-meeting-place of audio frequency) in Chang is set up and the first audio frequency respectively First communication link of other client in meeting-place, so due to main body machine (the i.e. first client) to In the one sub-meeting-place of audio frequency, the standard deviation of the network delay of other client is less so that other client's end group Originally the first audio signal can be synchronously received, if main body machine is receiving the one of the first audio signal This first audio signal is play again, so that all clients are broadcast in a sub-meeting-place of audio frequency after fixed response time Put the first audio signal substantially to tend to synchronizing；And owing to all clients in the sub-meeting-place of some audio frequency are broadcast The audio signal put is the most identical, and is the audio signal of the audio signal in the sub-meeting-place of other audio frequency, does not exists The sub-meeting-place of this audio frequency is play the sound in the sub-meeting-place of this audio frequency and produces acoustic feedback and utter long and high-pitched sounds.So due to this The method of bright embodiment can suppress the problem of uttering long and high-pitched sounds effectively so that the client in the sub-meeting-place of each audio frequency can To use the portable terminals such as mobile phone, and the terminal of voice communication that need not be special, reduce voice communication Cost.

It should be noted that the method for above-mentioned steps 101 to 104 is that the first client is at downlink reception first The process of audio signal, mainly has the following two kinds feelings for the first client in the process of up transmission signal Condition:

(1) in system as shown in Figure 1a, the first client can obtain pickup signal, by this pickup signal And first identification information in the sub-meeting-place of audio frequency, the signal after maybe pickup signal being processed at least one times And first the identification information in the sub-meeting-place of audio frequency be sent to audio mixing equipment, such audio mixing equipment can be by pickup signal Or at least one second audio frequency outside pickup signal and the first sub-meeting-place of audio frequency after processing at least one times After the audio signal in meeting-place carries out audio mixing, it is sent to the client in the 3rd sub-meeting-place of audio frequency.Wherein, It is to allow audio mixing equipment know this audio mixing equipment that one client sends the identification information in the first sub-meeting-place of audio frequency Which signal received is belonging to the sub-meeting-place of same audio frequency.

In one case, the first client, when obtaining pickup signal, can obtain this first client The first pickup signal.Signal after processing pickup signal at least one times is to the first ten obtained Tone signal carries out the signal after stereo echo Processing for removing.

In another case, the first client, when obtaining pickup signal, mainly obtains the first audio frequency The second pickup signal that in sub-meeting-place, other client (i.e. nonbody machine) sends and obtain the first client The first pickup signal.Signal after processing pickup signal at least one times is for the first pickup signal The audio signal in the first sub-meeting-place of audio frequency obtained after carrying out audio mixing with the second pickup signal, or to the first ten Tone signal carries out the signal after stereo echo Processing for removing, obtains after carrying out audio mixing with the second pickup signal The audio signal in the first sub-meeting-place of audio frequency.

In other cases, the first client, when obtaining pickup signal, mainly obtains the first audio frequency After what in meeting-place, other client (i.e. nonbody machine) sent carried out stereo echo Processing for removing the 3rd Pickup signal, and obtain the first pickup signal of the first client.Pickup signal is located at least one times Signal after reason be the 3rd pickup signal and the second pickup signal are carried out audio mixing after the first audio frequency of obtaining The audio signal in meeting-place, or the first pickup signal is carried out the signal after stereo echo Processing for removing, with The audio signal in the first sub-meeting-place of audio frequency that the 3rd pickup signal obtains after carrying out audio mixing.

It should be noted that above-mentioned two kinds of situations below are that the main body machine by the sub-meeting-place of each audio frequency should The audio signal in the sub-meeting-place of audio frequency is then forwarded to audio mixing equipment audio mixing again after carrying out audio mixing, the most permissible Shared a part of mixing operation by main body machine, alleviate the burden of audio mixing equipment.

(2) in system as shown in Figure 1 b, when the first client is being defined as the first sub-meeting-place of audio frequency During main body machine, the first client not only needs and sets up in the sub-meeting-place of the first audio frequency between other client One communication link, in addition it is also necessary to set up the second communication link between the main body machine in the sub-meeting-place of the second audio frequency. During such first client executing above-mentioned steps 102, it is to receive the second audio frequency by this second communication link The first audio signal that main body machine in meeting-place sends.And the first client is when up transmission signal:

First client can by each client in the first sub-meeting-place of audio frequency (include the first client and other Client) audio signal carry out audio mixing and obtain the second audio signal, then will by the second communication link Second audio signal is sent to the main body machine in the second sub-meeting-place of audio frequency, in order to the second audio mixing is believed by this main body machine Number it is sent to the nonbody machine in the second sub-meeting-place of audio frequency.Wherein the audio signal of each client can be each The pickup signal of individual client, or for the pickup signal of each client is carried out at stereo echo elimination Signal after reason.

The inventive method embodiment two

A kind of communication means comprising voice data is provided, mainly can apply to as illustrated in figs. ia and ib The communication system comprising voice data in, the method for the present embodiment is by the sub-meeting-place of audio frequency a certain in system As the method performed by the second client of nonbody machine, flow process in (the such as first sub-meeting-place of audio frequency) Scheme as shown in Figure 4, including:

Step 201, sets up the first communication link between the main body machine in the sub-meeting-place of the first audio frequency.

It is appreciated that user can operate the second client so that this second client joins a certain sound In the most sub-meeting-place (the such as first sub-meeting-place of audio frequency), such as can pass through " shaking ", or " face-to-face Build group " user operation instruction so that the second client together adds with the client of other voice communication In the first sub-meeting-place of audio frequency.In the present embodiment, add the multiple clients in the sub-meeting-place of same audio frequency The client in space the most within the specific limits.

After multiple clients join the first sub-meeting-place of audio frequency, can be by audio mixing equipment or third party device The network delay average arriving other client according to each client in a sub-meeting-place of audio frequency respectively determines The main body machine in the sub-meeting-place of this audio frequency and nonbody machine.The process specifically determined can have a following two ways:

(1) in the case of as shown in Figure 1a, after multiple clients join the first sub-meeting-place of audio frequency, Multiple clients just and are communicatively coupled between audio mixing equipment, can determine main body by audio mixing equipment Machine and nonbody machine.

In this case, for the second client, after performing following steps, can touch Send out the second client and start to perform the flow process of step 201 to 203: obtain the second client to the first audio frequency The network delay average of other client in meeting-place；The network delay average of the second client is sent to bag Audio mixing equipment in communication system containing voice data；If the network delay average ratio of the first client In the one sub-meeting-place of audio frequency, the network delay average of other client in addition to the first client is little, receives mixed The announcement information that sound equipment sends, this announcement information includes that the first client is as the first sub-meeting-place of audio frequency The information of main body machine.

Wherein, obtaining the second client can be as above-mentioned to the method for the network delay average of other client First client obtains the method for corresponding network delay average, does not repeats at this.

(2) in the case of as shown in Figure 1 b, after multiple clients join the first sub-meeting-place of audio frequency, Main body machine and nonbody machine can be determined by the third party device being all connected with multiple clients respectively. This third party device can be the management equipment etc. in system for multiple clients.

In this case, for the second client, after performing following steps, can touch Send out the second client and start to perform the flow process of step 201 to 203: obtain the second client to the first audio frequency The network delay average of other client in meeting-place；The network delay average of the second client is sent to Three method, apparatus；If except the first client in the sub-meeting-place of network delay average ratio the first audio frequency of the first client The network delay average of other client outside end is little, receives the announcement information that third party device sends, This announcement information includes first client information as the main body machine in the first sub-meeting-place of audio frequency.

Step 202, receives the first audio signal by the first communication link, and this first audio signal is first The audio signal of the audio signal in the sub-meeting-place of other audio frequency outside the sub-meeting-place of audio frequency.

Step 203, plays the first audio signal.
