First terminal and second terminal in two side's meetings switch to point-to-point call mode from conference model, need
Will be through overweight negotiation flow.As shown in Fig. 2 it illustrates a kind of heavy flow chart for consulting flow.In Fig. 2
In the shown flow of negotiation again, performed from first terminal side and consult flow again.The heavy negotiation flow is specific
It is as follows：
Step 21, IP-PBX send the first renegotiation request message to first terminal；
First renegotiation request message is used for the media capability complete or collected works for indicating first terminal feedback first terminal.The
The media capability complete or collected works of one terminal, refer to the total medium ability that first terminal is supported.Implement in the present invention
In example, media capability refers to the disposal ability to voice medium data, including coding/decoding capability, cryptographic capabilities
Deng.For example, IP-PBX sends ReInvite message to first terminal.
Correspondingly, first terminal receives the first renegotiation request message that IP-PBX is sent.
Step 22, first terminal sends the first response message to IP-PBX；
The media capability complete or collected works of first terminal are carried in first response message.For example, first terminal is to IP-PBX
200 OK message are sent, the media capability complete or collected works of first terminal are carried in the 200 OK message.
Correspondingly, IP-PBX receives the first response message that first terminal is sent.
Step 23, IP-PBX sends the second renegotiation request message to second terminal；
The media capability complete or collected works of first terminal are carried in second renegotiation request message, the second renegotiation request disappears
Cease for indicating that second terminal is complete according to the media capability complete or collected works of first terminal and the media capability of second terminal
Collection, determine that the media capability of first terminal and second terminal occurs simultaneously.The media capability complete or collected works of second terminal, it is
Refer to the total medium ability that second terminal is supported.First terminal and the media capability of second terminal occur simultaneously, and are
The media capability that finger first terminal and second terminal are supported.For example, the media capability complete or collected works bag of first terminal
Tri- kinds of media capability of A, B and C are included, the media capability complete or collected works of second terminal include tri- kinds of matchmakers of B, C and D
Ability of immigrants, then both media capability, which occur simultaneously, includes two kinds of media capability of B and C.For example, IP-PBX to
Second terminal sends ReInvite message, and the media capability complete or collected works of first terminal are carried in the ReInvite message.
Step 24, second terminal sends the second response message to IP-PBX；
The media capability that first terminal and second terminal are carried in second response message occurs simultaneously.For example, second is whole
Hold to IP-PBX and send 200 OK message, above-mentioned media capability is carried in the 200 OK message and is occured simultaneously.
Correspondingly, IP-PBX receives the second response message that second terminal is sent.
Step 25, IP-PBX sends the second confirmation message to second terminal；
Second confirmation message is used to indicate that IP-PBX has been successfully received above-mentioned media capability and occured simultaneously.For example,
IP-PBX sends ACK message to second terminal.
Correspondingly, second terminal receives the second confirmation message that IP-PBX is sent.
Step 26, IP-PBX sends the first confirmation message to first terminal；
IP-PBX sends the first confirmation message to first terminal, and above-mentioned media capability is carried in the first confirmation message
Occur simultaneously.For example, IP-PBX sends ACK message to first terminal, above-mentioned media are carried in the ACK message
Ability is occured simultaneously.
Correspondingly, first terminal receives the first confirmation message that IP-PBX is sent.
Step 27, first terminal and second terminal are occured simultaneously according to above-mentioned media capability establishes point-to-point call.
To can be seen that the negotiation flow of first terminal side be from receiving the to flow of consulting again as shown in Figure 2
One renegotiation request message starts, and terminates when the first confirmation message is received；And second terminal side
It is since being received the second renegotiation request message, and when the second confirmation message is received to consult flow
Terminate.Negotiation time needed for first terminal side can be more than the negotiation time needed for second terminal side.
Therefore, for the negotiation flow of two lateral terminals, " long to consult flow " and " short negotiation flow " are defined.Long association
Commodity-circulate journey, refer in flow is consulted again, first receive corresponding to a lateral terminal of renegotiation request message
Consult flow.Short negotiation flow, refer to again consult flow in, after receive the one of renegotiation request message
Negotiation flow corresponding to lateral terminal.It is long to consult the time-consuming time-consuming more than short negotiation flow of flow.
Based on this, pass through and the first terminal in two side's meetings and the floor status of second terminal detected,
Performed from a lateral terminal of non-speaking side and consult flow again so that a lateral terminal of non-speaking side is assisted using long
Commodity-circulate journey, and the lateral terminal of speaking party uses short negotiation flow, and then ensure the lateral terminal institute of speaking party
The negotiation time needed shortens as much as possible, between reducing sound card immediately.
Below by terms of the general character being related to based on invention described above embodiment, the embodiment of the present invention is entered
One step describes in detail.
Fig. 3 is refer to, it illustrates a kind of flow for the method for reclaiming conferencing resource provided in an embodiment of the present invention
Figure.This method can be applied in the IP-PBX110 in the application scenarios shown in Fig. 1.This method can include
Following steps.
Step 301, whether the target terminal detected in two side's meetings is speaking party, and target terminal is two side's meetings
In first terminal and second terminal in a terminal.
Step 302, when it is not speaking party to detect target terminal, perform from target terminal side and consult again
Flow；Wherein, consult flow again to be used to cause first terminal and second terminal to consult media capability again, with from
Conference model switches to point-to-point call mode.
Step 303, after consulting flow again and completing, the conferencing resource shared by two side's meetings is reclaimed.
In summary, the present embodiment provide method, pass through detection two side's meetings in target terminal whether be
Speaking party, when it is not speaking party to detect target terminal, is performed from target terminal side and consult flow again,
And after consulting flow again and completing, reclaim the conferencing resource shared by above-mentioned two sides meeting；Solve existing
The technical scheme that technology provides is likely to result in the overlong time of voice interim card, so as to seriously affect call matter
The problem of amount；Due in flow is consulted again, first receiving needed for a lateral terminal of renegotiation request message
Negotiation time is longer relative to another lateral terminal, consults to flow again by performing from a lateral terminal of non-speaking side
Journey a so that lateral terminal of non-speaking side consults flow using long, and the lateral terminal of speaking party uses short association
Commodity-circulate journey, to be reduced as far as the negotiation time needed for speaking party, namely reduce the media switching of speaking party
Time, between reaching reduction sound card immediately, improve the purpose of Session continuity and speech quality.
Fig. 4 is refer to, it illustrates the stream of the method for another recovery conferencing resource provided in an embodiment of the present invention
Cheng Tu.This method can be applied in the IP-PBX110 in the application scenarios shown in Fig. 1.This method can wrap
Include following steps.
Step 401, it is small that signaling plane transmission rate is chosen from the first terminal in two side's meetings and second terminal
One terminal, as target terminal.
Signaling plane transmission rate refers to the speed of terminal transmission signaling.In embodiments of the present invention, first terminal
Signaling plane transmission rate refer between first terminal and IP-PBX transmit signaling speed；The letter of second terminal
The face transmission rate of order refers to the speed that signaling is transmitted between second terminal and IP-PBX.
In a kind of possible embodiment, target terminal is chosen in the following way：
1st, first message is sent to first terminal, and the second message is sent to second terminal；
2nd, the first response corresponding to first message that first terminal is sent is received, and receives second terminal hair
The second response corresponding to the second message sent；
3rd, very first time at the time of calculating at the time of sending first message and receive the first response is poor, and
Calculate at the time of sending the second message and receive the second time difference at the time of the second response；
If the 4, very first time difference was more than for the second time difference, selection first terminal is target terminal；
If the 5, very first time difference was less than for the second time difference, selection second terminal is target terminal.
When the very first time, difference was more than for the second time difference, illustrate the signaling plane transmission rate of first terminal less than the
The signaling plane transmission rate of two terminals, therefore it is target terminal to choose first terminal；Conversely, work as the very first time
When difference was less than for the second time difference, illustrate that the signaling plane transmission rate of first terminal is more than the signaling plane of second terminal
Transmission rate, therefore it is target terminal to choose second terminal.
Alternatively, in order to further improve the accuracy of selection target terminal, it can use and obtain multiple time differences
The mode averaged determines the final time difference.Disappear for example, IP-PBX repeatedly sends first to first terminal
Cease and receive corresponding first response, it is poor so as to obtain multiple very first times and the plurality of very first time is poor
Average value it is poor as the final very first time；Similarly, IP-PBX repeatedly sends second to second terminal and disappeared
Cease and receive corresponding second response, so as to obtain multiple second time differences, and by the plurality of second time difference
Average value as the second final time difference.Pass through more above-mentioned final very first time difference and final the
Two time differences chose target terminal, were favorably improved the accuracy for choosing result.
In addition, under special circumstances, if very first time difference was equal to for the second time difference, IP-PBX can be from first
It is target terminal that any terminal is chosen in terminal and second terminal.
It should be noted that the mode of the selection target terminal of above-mentioned offer is only exemplary and illustratively,
IP-PBX can also use other manner to obtain the signaling plane transmission rate of two lateral terminals, or gather other available
In the parameter for the signaling plane transmission rate for reflecting two lateral terminals.For example, two lateral terminals report to IP-PBX respectively
Signaling plane transmission rate.
In the present embodiment, signaling plane transmission speed is chosen from the first terminal in two side's meetings and second terminal
A small terminal of rate, as target terminal, due to being from target terminal in the follow-up flow of negotiation again
Side rises to perform consults flow again, namely flow is consulted in target terminal side using long, and non-targeted end
Side is held using short negotiation flow, because the signaling plane transmission rate of non-targeted terminal is bigger, therefore can
Further reduce the time-consuming of short negotiation flow.Wherein, when target terminal is first terminal, non-targeted terminal
For second terminal；Or when target terminal is second terminal, non-targeted terminal is first terminal.
Step 402, detect whether target terminal is speaking party.
MRS periodically can send speaking party's information to IP-PBX, and speaking party's information is used to indicate that speaking party institute is right
The terminal answered.Correspondingly, IP-PBX receives speaking party's information that MRS is sent, and detects target terminal accordingly
Whether it is speaking party.
For example, MRS is spaced to IP-PBX at predetermined time intervals sends speaking party's information, such as the pre- timing
Between at intervals of 1 second.For another example MRS when detecting that speaking party changes, sends to IP-PBX and sent out
The side's of saying information.
Step 403, when it is not speaking party to detect target terminal, perform from target terminal side and consult again
Flow.
That is, when it is mute state to detect target terminal, is performed from target terminal side and consult stream again
Journey.Consult flow again to be used to cause first terminal and second terminal to consult media capability again, with from conference model
Switch to point-to-point call mode.By the agency of, media capability refer to the place to voice medium data above
Reason ability, including coding/decoding capability, cryptographic capabilities etc..
Specifically, this step includes following several sub-steps：
1st, the first renegotiation request message is sent to target terminal；
First renegotiation request message is used for the media capability complete or collected works for indicating target terminal feedback target terminal.
2nd, the media capability complete or collected works for the target terminal that target terminal is sent are received；
3rd, the second renegotiation request message is sent to non-targeted terminal；
The media capability complete or collected works of target terminal are carried in second renegotiation request message, the second renegotiation request disappears
Cease for indicating non-targeted terminal according to the media capability complete or collected works of target terminal and the media capability of non-targeted terminal
Complete or collected works, determine that the media capability of target terminal and non-targeted terminal occurs simultaneously.
4th, the media capability that non-targeted terminal is sent is received to occur simultaneously；
5th, send media capability to target terminal to occur simultaneously, to cause target terminal and non-targeted terminal according to media
Ability, which is occured simultaneously, establishes point-to-point call.
About the above-mentioned heavy particular content for consulting flow, reference can be made to introduction in above-mentioned embodiment illustrated in fig. 2 and
Illustrate, the present embodiment repeats no more to this.
Step 404, after consulting flow again and completing, the conferencing resource shared by two side's meetings is reclaimed.
The conferencing resource that IP-PBX is reclaimed may include audio mixing resource.By detecting target meeting by two sides
When above meeting is changed into two side's meetings, flow is consulted in execution again, with cause first terminal in two side's meetings and
Second terminal switches to point-to-point call mode from conference model, to reach the purpose of release recovery conferencing resource.
In addition, by after consulting flow again and completing, reclaiming the conferencing resource shared by two side's meetings, can
Avoid causing because reclaiming conferencing resource too early the dropped calls between first terminal and second terminal or even break
Open.
In summary, the present embodiment provide method, pass through detection two side's meetings in target terminal whether be
Speaking party, when it is not speaking party to detect target terminal, is performed from target terminal side and consult flow again,
And after consulting flow again and completing, reclaim the conferencing resource shared by above-mentioned two sides meeting；Solve existing
The technical scheme that technology provides is likely to result in the overlong time of voice interim card, so as to seriously affect call matter
The problem of amount；Due in flow is consulted again, first receiving needed for a lateral terminal of renegotiation request message
Negotiation time is longer relative to another lateral terminal, consults to flow again by performing from a lateral terminal of non-speaking side

53 can perform after step 51, can also be performed before step 51, or be performed simultaneously with step 51.
In view of IP-PBX receive some terminal (hereinafter referred to as " requesting terminal ") transmission be used for please
Seek the request message for creating target meeting, and after creating target meeting, requesting terminal will can need to invite into
The list for entering other terminals of target meeting is sent to IP-PBX, and IP-PBX is according to the other terminals of list outgoing call
Add meeting.In the process, IP-PBX is typically only capable to enough get the media capability complete or collected works of requesting terminal,
And in the other terminals joining the conferences of outgoing call, the media capability complete or collected works of the requesting terminal can be sent to other by IP-PBX
Terminal, by its media capability common factor with requesting terminal of each self feed back of other terminals.So, target meeting is worked as
When being changed into two side's meetings from two side's above meetings, IP-PBX can not accurately be known final remaining in two side's meetings
The media capability complete or collected works of two terminals, and then cause detecting two terminals with the presence or absence of media capability common factor
When in the presence of detection mistake possibility.
In one example, it is assumed that the media capability complete or collected works of requesting terminal include tri- kinds of media energy of A, B and C
Power, the media capability complete or collected works that outgoing call adds other terminals 1 of target meeting include two kinds of media capability of B and D,
The media capability complete or collected works that outgoing call adds other terminals 2 of target meeting include two kinds of media capability of C and D.Please
Seeking terminal, the media capability that requesting terminal is sent to IP-PBX is complete when asking IP-PBX to create target meeting
Collection.The media capability complete or collected works of requesting terminal are sent to other by IP-PBX in other 1 membership of terminal of outgoing call
Terminal 1, other terminals 1 determine therefrom that the media capability common factor of itself and requesting terminal is media capability B, concurrently
Give IP-PBX.IP-PBX sends out the media capability complete or collected works of requesting terminal in other 2 membership of terminal of outgoing call
Other terminals 2 are given, other terminals 2 determine therefrom that the media capability common factor of itself and requesting terminal is media capability
C, and it is sent to IP-PBX.Assuming that target meeting is first left in requesting terminal, it is left other terminals 1 and other
Terminal 2 enters two side's meetings, because IP-PBX is in early stage conversation procedure, does not get other terminals 1
With the media capability complete or collected works of other terminals 2, IP-PBX will be considered that other terminals 1 and other terminals 2 are not present
Media capability occurs simultaneously.And it is substantial, media capability common factor be present in other terminals 1 and other terminals 2,

Assuming that IP-PBX to first terminal send session outside message at the time of be T1, receive first terminal
It is T2 at the time of media capability complete or collected works, then very first time difference is T2-T1.
2nd, calculate to second terminal send session outside message at the time of and receive second terminal media capability it is complete
The second time difference at the time of collection；
Assuming that IP-PBX to second terminal send session outside message at the time of be T3, receive second terminal
It is T4 at the time of media capability complete or collected works, then the second time difference was T4-T3.
If the 3, very first time difference was more than for the second time difference, selection first terminal is target terminal；
If the 4, very first time difference was less than for the second time difference, selection second terminal is target terminal.
For example, when T2-T1 is more than T4-T3, it is target terminal that IP-PBX, which chooses first terminal,；Work as T2-T1
During less than T4-T3, it is target terminal that IP-PBX, which chooses second terminal,.
Step 505, detect whether target terminal is speaking party.
Step 506, when it is not speaking party to detect target terminal, perform from target terminal side and consult again
Flow.
