Step 401, the voice conferencing server is consulted to set up the acoustic energy passage by call signaling (for example Session Initiation Protocol or H.323 agreement etc.) and voice terminal, and voice terminal and multicast network are set up sound channel.Wherein, sound channel is used for voice terminal and multicast network interactive voice signal; The acoustic energy passage, be used for RTP (the Real-time Transport Protocol that the voice conferencing server uses standard, RTP) agreement receives the acoustic energy information that voice send terminal, for example, voice conferencing server and voice terminal pass through SIP (Session Initiation Protocol, session initiation protocol) (the Service Discovery Protocol of the SDP in the agreement, service discovery protocol) a message expansion PayLoad (payload) type negotiates an acoustic energy passage.
Wherein, when voice sent terminal and set up sound channel with multicast network, this voice transmission terminal was source terminal (being multicast source), and the address of this multicast network is destination address (being multicast group address).
Step 402, voice send terminal after collecting voice messaging, judge that these voice send terminal and whether have the function of calculating acoustic energy according to voice messaging, if having, then set up the acoustic energy passage with the voice conferencing server, forward step 403 to.The acoustic energy passage of this foundation is that voice conferencing server and voice send the acoustic energy passage that terminal is consulted, in the step 401, these voice send terminal and multicast network has been set up sound channel, at this moment, can determine the corresponding relation of sound channel and sound energy channel, promptly set up the corresponding relation of the acoustic energy of voice messaging and this voice messaging; Do not have when calculating the function of acoustic energy when voice send terminal, only set up the sound channel that voice send terminal and multicast network, forward step 407 to according to voice messaging.
Step 403, voice send terminal and have the function of calculating acoustic energy according to voice messaging, then after gathering voice messaging, calculate the acoustic energy of this voice messaging; This voice messaging and corresponding acoustic energy are encoded, on the timestamp of RTP message that sends voice messaging and the RTP message that sends corresponding acoustic energy, stamp the identical time then, so that the voice conferencing server is determined this voice messaging in the acoustic energy of this time period according to timestamp, and the acoustic energy of this voice messaging correspondence is sent to the voice conferencing server by the acoustic energy passage.
Among the present invention, voice send terminal after collecting voice messaging, also will this voice messaging be sent in the multicast network by sound channel, can also carry the address information (, being used to distinguish the source terminal that sends this voice messaging) of this voice transmission terminal in this voice messaging when a plurality of voice send terminals when same multicast group address sends voice messaging.Wherein, voice send terminal and send the not ordinal relation of priority of the pairing acoustic energy of this voice messaging to multicast network transmission voice messaging and voice transmission terminal to the voice conferencing server.
Step 404, voice conferencing server receive from each acoustic energy passage from a plurality of voice and send the acoustic energy information that terminal sends; Compare each road acoustic energy, relatively acoustic energy is not directly to compare sound energy value, and will give higher weight to the sound that is transmitting, and makes sound withdraw from gradually.For example, during initial the comparison, the weight assignment of acoustic energy maximum is 2, in secondary comparison, directly compare acoustic energy earlier, if the energy value of this road sound has not been a maximum, then the weight of this road sound is reduced to 1.8, and the acoustic energy that this road acoustic energy be multiply by after the weight with maximum again compares, still the acoustic energy than current maximum is big after multiply by weight as this road acoustic energy, then also use these original road voice,, then use the acoustic energy of current maximum if this road acoustic energy multiply by after the weight less than the acoustic energy of current maximum.
Step 405, the voice conferencing server draws the highest two-way voice messaging of energy according to the energy comparison algorithm, and remove receiving speech information in the multicast source address by signaling indication voice receiving terminal correspondence from multicast network, this signaling is the signaling of expansion, and purpose is the address of indication voice receiving terminal changes " source ".Wherein, selecting the two-way voice messaging is avoid the sound switching too frequent, and the unexpected variation of background sound causes user's incompatibility.
Wherein, the voice conferencing server is receiving when sending the acoustic energy information of terminals from a plurality of voice, obtain the IP address information that voice send terminal, after calculating the highest two-way voice messaging of energy, the pairing IP address information of this two-way voice messaging is added in the signaling, and this signaling sent to voice receiving terminal (can for a plurality of), and carried the IP address information (sign of the two-way voice signal that acoustic energy is the highest) of multicast source (voice transmission terminal) in this signaling.Wherein, in multicast network, multicast is that the packet that allows one or more senders (multicast source) to send arrives a plurality of recipients (once, network technology simultaneously), multicast source sends to particular multicast group to packet, and the address that only belongs to this multicast group just can receive packet, thereby saves the network bandwidth greatly.Among the present invention, the packet that multicast source will carry voice messaging sends to multicast network, the voice messaging of the different multicast sources of storage (different voice send terminal) in multicast network, recipient in this particular multicast group (voice receiving terminal) is when needing receiving speech information, and multicast network sends to the voice receiving terminal with the voice messaging of correspondence.
A plurality of voice receiving terminals are after receiving above-mentioned signaling, send message to multicast network respectively, the destination address of this message is a multicast group address, and has carried the IP address information (the pairing voice of the two-way voice messaging that energy is the highest send the IP address information of terminal) of multicast source in this message.Wherein, these a plurality of voice receiving terminals are the different recipients in the multicast group of multicast network place.
Multicast network is after the message that receives from a plurality of voice receiving terminals, obtain the IP address information (the pairing voice of the two-way voice messaging that energy is the highest send the IP address of terminal) of the multicast source that carries in the message, find the pairing voice messaging of this multicast source IP address (the two-way voice messaging that energy is the highest), and this voice messaging is sent to a plurality of voice receiving terminals.
Step 406, the voice receiving terminal is decoded to this two-way voice messaging, and decoded two-way voice messaging is carried out audio mixing, then output.
Step 407, when voice transmission terminal does not have according to the function of voice messaging calculating acoustic energy, voice send terminal according to the sound channel between voice transmission terminal and the multicast network, and voice messaging is sent to multicast network, carry the address information that these voice send terminal in this voice messaging.These voice send terminal and send message to the voice conferencing server, have carried the voice messaging that sends terminal through the voice of coding in this message, and the voice conferencing server is decoded to voice messaging, and carry out energy meter and calculate and the energy comparison procedure.Forward step 405 to.
The foregoing description is the example explanation the two-way voice signal is carried out audio mixing only, also can carry out audio mixing to the above voice signal of two-way in the practical application, but implementation procedure is distinguished to some extent.For example carry out audio mixing, need between voice conferencing server and voice terminal, set up 3 acoustic energy passages in advance for 3 road voice signals; The voice conferencing server receives voice messaging and the corresponding acoustic energy that sends terminal from least three voice, these acoustic energy are compared, obtain the highest three of acoustic energy, respectively 3 the acoustic energy passages of these three voice messagings that acoustic energy is the highest by correspondence are sent to the voice receiving terminal, this three road voice messaging of voice receiving terminal is decoded, and decoded three road voice messagings are carried out audio mixing output.
