Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, it then follows regard the association of networking View, the stopping transmission instruction of the view networked terminals forwarding is received by the terminal attended a meeting, and the terminal attended a meeting is passed according to the stopping Defeated instruction stops transmitting data to the view networked server, realizes that terminal of attending a meeting actively stops to the view networked server Transmit data, the purpose of the bandwidth of release busy.
When inventor has found that terminal carries out meeting in view networking, if the terminal attended a meeting receives audio, video data needs When downlink bandwidth is unsatisfactory for requiring, the speech end audio-video picture which watches just will appear Caton or packet loss phenomenon, this When need the control of chairman end that the terminal kicked out of meeting or the terminal more switching network just to meet the requirement for receiving data, or Person end of making a speech reduces the bandwidth that the audio, video data sent needs, and if after the terminal kicked out of thoroughly exits meeting, need Request for conference is sent from chairman end to the terminal for thoroughly exiting meeting again, meeting can be just added in these terminals again, again group Meeting is built, thus can delay the long period, and reduces the working efficiency of view networked server.In view of the above-mentioned problems, invention People is creative when proposing in session by further investigation, both can guarantee that each terminal attended a meeting normally received the sound of meeting Video pictures, and can guarantee that the downlink bandwidth of terminal audio, video data meets to receive and require, the present invention program is carried out below Detailed explanation and illustration.
Fig. 5 shows a kind of flow chart of controlling terminal method of the embodiment of the present invention, and wherein terminal is the end in view networking End includes: at least two terminals depending on networking, transmits data, controlling terminal by view networked server between these two terminals Method include the following steps:
Step 501: in the case where the rest network bandwidth of first terminal is less than current desired bandwidth, depending on networked server It receives the stopping transmission that second terminal is sent to instruct, stops the view networking number of carrying first terminal in transmission instruction；Wherein, Two terminals are the terminal of initiating conference, and first terminal is the terminal for participating in the meeting that second terminal is initiated.
In the embodiment of the present invention, when needing to have a meeting depending on each terminal in networking, need by chairman end come initiating conference, chairman End is the terminal that can control meeting, certainly, if control program in Pamir is fitted in multiple terminals, then by wherein one The terminal of a initiating conference is served as chair end (second terminal), and after meeting establishment, the terminal of only initiating conference can be used Pamir controls program and controls meeting, remaining be equipped with Pamir control program attend a meeting terminal cannot use have a Pamir Program is controlled to control meeting.
Depending on networked server by between chairman end and each terminal of attending a meeting transmit data Path Setup it is good after, chairman End speech can make a speech, if needing to attend a meeting the speech of some terminal, chairman end controls program by Pamir can be real The terminal speech of attending a meeting for now needing to make a speech.
During in session, if the first terminal attended a meeting can not normally watch the audio-video picture at speech end, i.e., First terminal rest network bandwidth be less than current desired bandwidth in the case where, as chairman end second terminal to view the Internet services Device sends to stop transmitting and instruct, and stops the view networking number of carrying first terminal in transmission instruction.
As an example: having 3 terminals in session, the second terminal view networking number of initiating conference: 010- 6888999, other two terminal (i.e. first terminal) attended a meeting is respectively as follows: 028-3335558 and 0990- depending on networking number 9998889,010-6888999 terminals with regard networked server progress data interaction maximum bandwidth as 100M, 028-3335558 Terminal with regard networked server carry out data interaction maximum bandwidth as 80M, 0990-9998889 terminal with regard networked server The maximum bandwidth for carrying out data interaction is 50M, it is assumed that the upstream bandwidth and downlink bandwidth of this 3 terminals are average occupancy, then 010-6888999 terminal uplink bandwidth and downlink bandwidth are respectively 50M, 028-3335558 terminal uplink bandwidth and downlink bandwidth Respectively 40M, 0990-9998889 terminal uplink bandwidth and downlink bandwidth are respectively 25M.After meeting starts, 010-6888999 Terminal is to the bandwidth for regarding the audio-video picture needs that networked server is sent as 20M (i.e. upstream bandwidth occupies 20M), 028- The audio-video that 3335558 terminals and 0990-9998889 terminal receive the 010-6888999 terminal of view networked server forwarding is drawn Face needs 20M downlink bandwidth, and the two all meets, then 028-3335558 terminal and 0990-9998889 terminal can be received normally See the audio-video picture of 010-6888999 terminal.When 010-6888999 terminal is because of various aspects factor, so that itself joins to view The bandwidth that the audio-video picture that network server is sent needs becomes 30M (i.e. upstream bandwidth occupies 30M), 028-3335558 terminal The audio-video picture for receiving the 010-6888999 terminal forwarded depending on networked server with 0990-9998889 terminal needs 30M Downlink bandwidth, 028-3335558 user equipment downlink bandwidth 40M meets the condition, but 0990-9998889 user equipment downlink bandwidth at this time Condition is not satisfied by 25M, i.e., 0990-9998889 terminal residual network bandwidth is less than current desired bandwidth, then 010- 6888999 terminals stop transmission instruction to view networked server transmission, the view networking number of carried terminal in this instruction: 0990-9998889.If 010-6888999 terminal is because of various aspects factor, so that the sound view that itself sends to view networked server The bandwidth that frequency picture needs becomes 45M (i.e. upstream bandwidth occupies 45M), 028-3335558 terminal and 0990-9998889 terminal The audio-video picture for receiving the 010-6888999 terminal forwarded depending on networked server needs 45M downlink bandwidth, at this time 028- Condition is not satisfied by 3335558 user equipment downlink bandwidth 40M, and also condition is not satisfied by 0990-9998889 user equipment downlink bandwidth 25M, That is 028-3335558 terminal and 0990-9998889 terminal residual network bandwidth is both less than current desired bandwidth, then 010- 6888999 terminals stop transmission instruction to view networked server transmission, the view networking number of carried terminal in this instruction: 028- 3335558 terminals and 0990-9998889.
There are also the presence of another situation, in session during, if view networked server need transmit or forward One or more significant data, but the network bandwidth for regarding networked server is occupied excessive, remaining idle Netowrk tape Width is less than required bandwidth, i.e., remaining idle network bandwidth is not able to satisfy the transmission of view networked server or forwarding significant data Requirement.Such as: the network bandwidth of networked server is regarded as 1,000,000,000 (M), there are 100 terminals in session, initiating conference is First terminal view networking number: 010-6888999, this 100 terminals occupy the network bandwidth of 800M when meeting, view networking clothes Be engaged in device residue idle network bandwidth 200M, it is assumed that this 100 terminals are average occupancy, then 1 terminal just occupies the network of 8M Bandwidth, wherein 1 terminal occupies the network bandwidth of view networked server 4M to view networked server transmission data, depending on the Internet services Device sends the network bandwidth that data occupy view networked server 4M to 1 terminal, and the important number transmitted is needed depending on networked server It just can satisfy transmission requirement according to the network bandwidth of 300M to be had, then 010-6888999 terminal is sent to view networked server Stop transmission instruction, stopping transmission instruction is for discharging each occupied network bandwidth of terminal of attending a meeting.
Step 502: view networked server is in response to stopping transmission instruction, to the corresponding first terminal forwarding of view networking number Stop transmission instruction.
In the embodiment of the present invention, depending on networked server in response to stopping transmission instruction, to view networking number corresponding first Terminal forwarding stops transmission instruction, and stopping transmission instruction includes: the view networking number of second terminal.This view networking number Effect: allow receive view networked server forwarding instruction terminal verified used in, as to how verify, later accordingly Place is explained in detail and illustrates, does not repeat them here first herein.
Continue to continue to use above-mentioned example, when 0990-9998889 user equipment downlink bandwidth 25M is unsatisfactory for receiving 010-6888999 end When holding audio-video picture demand, 010-6888999 terminal is sent to view networked server stops transmission instruction, takes in this instruction The view networking number of tape terminal: 0990-9998889.
In the presence of another situation:
The terminal of 010-6888999 is controlled program and sent to view networked server by Pamir stops transmission instruction, should Stop including needing to stop number of networking to the view of the terminal of attending a meeting depending on networked server transmission data in transmission instruction, because needing The network bandwidth of 300M is discharged, then needing to discharge 75 terminals of attending a meeting, (1 terminal is occupied to view networked server transmission data Depending on the network bandwidth of networked server 4M, so 75*4M=300M) occupy network bandwidth, stop transmission instruction includes Need to stop number of networking to the view of 75 terminals of attending a meeting depending on networked server transmission data, it is of course also possible to which 100 are joined The network bandwidth that meeting terminal occupies all discharges, and releases 400M (100*4M=400M) network bandwidth.
Step 503: first terminal stops in response to stopping transmission instruction to view networked server transmission data.
In the embodiment of the present invention, stops transmission to the corresponding first terminal forwarding depending on number of networking depending on networked server and refer to It enables, stopping transmission instruction is networked other than number in addition to carrying the view of second terminal, further includes: the view networking number of second terminal The physical address and action type of code, view networked server.The wherein view networking number and view networked server of second terminal Physical address verified for subsequent first terminal used, as to how verifying, corresponding position is explained in detail later And explanation, it not repeating them here first herein, action type is used to that first terminal to be allowed to execute corresponding operation according to the content of action type, Corresponding position is explained in detail and illustrates later with content for the specific classification of action type, does not repeat them here first herein.
First terminal is networked after receiving the stopping transmission instruction of view networked server forwarding according to the view of second terminal Number, regard networked server physical address and action type, determine stop to view networked server transmit data, discharge to Depending on the upstream bandwidth that networked server transmission data occupy, but networked server is regarded still whole to first terminal transmission second The data at end, such first terminal can still watch the audio-video picture of second terminal, not influence being normally carried out for meeting. It ensures that first terminal normally watches the audio-video picture of second terminal in this way, ensure that the quality of picture, be not in card And the phenomenon that packet loss.
Continue to continue to use above-mentioned example, when 0990-9998889 user equipment downlink bandwidth 25M is unsatisfactory for receiving 010-6888999 end When holding audio-video picture demand, 010-6888999 terminal is sent to view networked server stops transmission instruction, takes in this instruction The view networking number of tape terminal: 0990-9998889.0990-9998889 terminal receives stopping transmission instruction, and verifies logical It crosses, 0990-9998889 terminal stops just releasing the bandwidth of 25M, i.e. 0990- after view networked server transmission data 9998889 terminals release upstream bandwidth, and the 25M of upstream bandwidth is all added on downlink bandwidth, so that downlink bandwidth reaches 50M meets the bandwidth requirement for receiving 010-6888999 terminal audio-video picture
Optionally, step 503 can specifically include following steps:
Step 503a: first terminal transmits the second terminal in instructing after receiving stopping transmission instruction, to stopping Depending on networking number and verified depending on the physical address of networked server.
In the embodiment of the present invention, first terminal is transmitted according to stopping and is wrapped in instructing after receiving stopping transmission instruction Include: second terminal is verified depending on networking number and depending on the physical address of networked server, the purpose of verification: so that the One terminal determine stop transmission instruction whether be initiating conference second terminal demand itself stop to view networked server transmission Data.Because depending on networked server more than one, at the same these depending between networked server but be connected with each other and can be into The interaction of row instruction and data, one is the terminal for being connected to enormous amount simultaneously depending on networked server, these terminals are referred to Enable and data interaction be also all by being completed depending on networked server, so depending on networked server might have error when It waits, for example is issued to the instruction of A terminal and has issued B terminal, if B terminal directly executes after receiving instruction without verifying, It so just will appear mistake.Therefore such a verification scheme is required, to guarantee entirely to regard the normal operation of intranet network.
Step 503b: if it is determined that second terminal is the second terminal for initiating the participated in meeting of first terminal depending on networking number Corresponding view networking number, and be the view networked server pair that first terminal transmits data depending on the physical address of networked server The physical address answered, then first terminal stops according to action type to view networked server transmission data.
In the embodiment of the present invention, if first terminal is by verification, determine second terminal is initiation the depending on networking number The corresponding view networking number of the second terminal of the participated in meeting of one terminal, and be first whole depending on the physical address of networked server The corresponding physical address of view networked server of end transmission data, then first terminal stops according to action type to view networking clothes Business device transmits data.Wherein action type includes: and stops sending, alternatively, stopping sending and receiving；Wherein, stop sending being used for Instruction first terminal stops sending data to view networked server, but first terminal still can receive the sound of second terminal Video pictures；Another stopping send and receive be used to indicate first terminal stop to view networked server send data, and Stopping receiving the data that view networked server is sent, i.e., first terminal neither sends data and gives view networked server at this time, Also do not receive to regard the data that networked server is sent, first terminal thoroughly exits meeting.
Continue to continue to use above-mentioned example, it is assumed that the first terminal for needing to discharge has 1, corresponding view networking number are as follows: 0990- 9998889, the meeting of participation is that the terminal of 010-6888999 is initiated, and stops transmitting instructions to depending on networked server forwarding 0990-9998889 terminal: stop including: second terminal view networking number: 010-6888999, view the Internet services in transmission instruction The physical address of device: 2e:305b:3b:ce:43, action type: stop sending；0990-9998889 terminal receives stopping and passes After defeated instruction, whether verification second terminal regards networking number as 010-6888999, and the physical address verified depending on networked server is No is 2e:305b:3b:ce:43, if check results: second terminal is 010-6888999 depending on networking number, and verifies view connection The physical address of network server is 2e:305b:3b:ce:43, then first terminal is according to action type: stopping sending, actively stop Data is sent to view networked server.If check results wherein have any one not meet, then 0990-9998889 is whole Any operation is not carried out in end, continues to participate in the meeting that second terminal 010-6888999 is initiated.
If in the above process, 0990-9998889 terminal receives the action type for stopping including in transmission instruction are as follows: Stopping sends and receives, then 0990-9998889 terminal is after verification passes through, according to action type: stopping sends and receives, and stops Data only are sent to view networked server, and stop receiving the data that view networked server is sent, later 0990-9998889 Terminal just thoroughly exits meeting.
In the presence of another situation:
Assuming that need there are two the second terminals that discharge, corresponding view networking number be respectively as follows: 028-3335558 with 0990-9998889, the meeting of participation are that the terminal of 010-6888999 is initiated, and forward depending on networked server and stop transmission instruction It is given to 028-3335558 terminal and 0990-9998889 terminal: stopping including: second terminal view networking number in transmission instruction: 010-6888999, the physical address for regarding networked server: 2e:305b:3b:ce:43, action type: stop sending；028- After 3335558 terminals and 0990-9998889 terminal receive stopping transmission instruction, whether verification second terminal view networking number For 010-6888999, verification regards the physical address of networked server whether as 2e:305b:3b:ce:43, if check results: the Two terminals are 010-6888999 depending on networking number, and the physical address verified depending on networked server is 2e:305b:3b:ce: 43, then first terminal is according to action type: stopping sending, actively stops sending data to view networked server.If school Testing result wherein has any one not meet, then any behaviour is not carried out in 028-3335558 terminal and 0990-9998889 terminal Make, continues to participate in the meeting that second terminal 010-6888999 is initiated.
If in the above process, 028-3335558 terminal and 0990-9998889 terminal are received in stopping transmission instruction Including action type are as follows: stopping send and receive, then 028-3335558 terminal and 0990-9998889 terminal pass through in verification Afterwards, according to action type: stopping sends and receives, and stops sending data to view networked server, and stops receiving view networking The data that server is sent, 028-3335558 terminal and 0990-9998889 terminal just thoroughly exit meeting later.
Optionally, referring to Fig. 6, after step 504, the method for controlling terminal further include:
Step 601: detecting whether to receive the transmission data from first terminal depending on networked server.
In the embodiment of the present invention, after first terminal stops sending data to view networked server, depending on the Internet services Device has whether corresponding mechanism active detecting receives the transmission data from first terminal.
Step 602: if within a preset time, not receiving the transmission data from first terminal depending on networked server, then Pause confirmation instruction is issued to second terminal depending on networked server.
In the embodiment of the present invention, is passing through the preset time, do not receiving the biography from first terminal depending on networked server Transmission of data, then can issue pause confirmation instruction to second terminal depending on networked server, the instruction is for telling second terminal, the One terminal has stopped transmitting data.
Continue to continue to use above-mentioned example, it is assumed that the first terminal for needing to discharge has 1, corresponding view networking number are as follows: 0990- 9998889, preset time is 2 seconds, and the meeting of participation is that the terminal of 010-6888999 is initiated；In 0990-9998889 terminal Actively stop after sending data to view networked server, was all not received by 0990- within 2 second time depending on networked server The data that 9998889 terminals are sent then issue pause confirmation instruction to second terminal 010-6888999 depending on networked server.
In the presence of another situation:
Assuming that need there are two the second terminals that discharge, corresponding view networking number be respectively as follows: 028-3335558 with 0990-9998889, preset time are 2 seconds, and the meeting of participation is that the terminal of 010-6888999 is initiated；In 028-3335558 Terminal and 0990-9998889 terminal actively stop after sending data to view networked server, depending on networked server at 2 seconds It is all not received by the respective data that 028-3335558 terminal and 0990-9998889 terminal are sent in time, then regards networking Server issues pause confirmation instruction to second terminal 010-6888999.
If it should be noted that causing in 028-3335558 terminal and 0990-9998889 terminal because of various factors Any one terminal transmits data to view networked server again after 2 seconds, although the terminal is again to view networking clothes Business device transmission data occupies the network bandwidth of view networked server, but will not issue to second terminal depending on networked server Any instruction, second terminal still can execute corresponding operation according to pause confirmation instruction, how to regard networked server It can be when any one terminal be after preset time and sends data to view networked server, under trend second terminal The corresponding instruction of hair, allow the state for knowing first terminal of second terminal promptly and accurately be the present inventor The problem solved.
Step 603: second terminal is temporary in the display interface output first terminal of second terminal in response to pause confirmation instruction Stop the information of transmission data.
In the embodiment of the present invention, after second terminal receives the pause confirmation instruction issued depending on networked server, just the The information of the display interface output first terminal pause transmission data of two terminals, user can pass through the display interface of second terminal Intuitively know that very much first terminal is in the state of pause transmission data, or if first terminal is thoroughly to exit meeting, that What is issued to second terminal depending on networked server is exactly the instruction for exiting meeting, and can be shown on the display interface of second terminal One terminal is in the state for exiting meeting.
Optionally, after step 607, the method for controlling terminal further include:
Step 604: second terminal is sent to view networked server restores transmission instruction, restores to carry first in transmission instruction The view networking number of terminal；
In the embodiment of the present invention, after first terminal stops sending data to view networked server, if second is whole End needs to restore first terminal and sends data to view networked server, then second terminal is sent to view networked server restores transmission Instruction restores the view networking number that first terminal can be carried in transmission instruction.
Step 605: view networked server is in response to restoring transmission instruction, to the corresponding first terminal forwarding of view networking number Restore transmission instruction；
Step 606: first terminal transmits data in response to restoring transmission instruction, to view networked server；
In the embodiment of the present invention, after receiving recovery transmission instruction depending on networked server, the view just carried into instruction joins The corresponding first terminal of network No. code issues recovery transmission instruction, after corresponding first terminal receives recovery transmission instruction, again Actively to sending itself data depending on networked server.Restoring transmission instruction includes: second terminal view networking number, view networking clothes The physical address of business device, action type: restore transmission.
Continue to continue to use above-mentioned example, it is assumed that the terminal of 010-6888999 needs 0990-9998889 terminal to view networking clothes Business device sends data, then sends to view networked server and restore to transmit instruction, be transmitted to the instruction depending on networked server 0990-9998889 terminal, 0990-9998889 terminal respond the instruction, and verification first terminal regards networking number as 010- 6888999, the physical address of networked server is regarded as 2e:305b:3b:ce:43, according to action type: restoring transmission, 0990- 9998889 terminals actively transmit data to view networked server and send data to view networked server, attend a meeting at this time 010-6888999 and 028-3335558 terminal it is seen that 0990-9998889 terminal audio-video picture.
In the presence of another situation:
Assuming that first terminal 010-6888999 needs 028-3335558 terminal and 0990-9998889 terminal to network to view Server sends data, restores transmission instruction to view networked server transmission, forwards recovery transmission to refer to depending on networked server It enables to 028-3335558 terminal and 0990-9998889 terminal, 028-3335558 terminal and 0990-9998889 terminal receive Restore transmission instruction after, verification first terminal regard network number as 010-6888999, regard the physical address of networked server as 2e:305b:3b:ce:43, according to action type: restoring transmission, 028-3335558 terminal and 0990-9998889 terminal are actively Data is transmitted to view networked server.
It should be noted that the rest network bandwidth that the above method is applied to the first terminal attended a meeting incessantly is less than current institute When the case where needing bandwidth, when second terminal is not desired to watch the audio-video of any one terminal of attending a meeting, stopping can be sent and passed Defeated instruction carrys out the terminal so that any one is attended a meeting and stops transmitting data to view networked server, at this moment the uplink band of the terminal of attending a meeting Width just frees out, and can be used by downlink bandwidth, increase downlink bandwidth.
For example, referring to Fig. 7, the equipment of the embodiment of the present invention schematic diagram needs to have a meeting, pacify depending on 5 terminals in networking Terminal equipped with Pamir control program is to regard networking number as 010-6888999, in addition 4 terminal view networking number difference Are as follows: 028-3335558,0990-9998889,026-5479431 and 030-1578459, physically depending on networked server Location: 2e:305b:3b:ce:43, preset time are 2 seconds, and 010-6888999 terminal and view networked server carry out data interaction Maximum bandwidth is 100M, 028-3335558 terminal with regard the maximum bandwidth of networked server progress data interaction as 80M, 0990- 9998889 terminals with regard networked server carry out data interaction maximum bandwidth as 60M, 026-5479431 terminal with regard networking The maximum bandwidth that server carries out data interaction is 70M, and 030-1578459 terminal and view networked server carry out data interaction Maximum bandwidth is 60M, it is assumed that the upstream bandwidth and downlink bandwidth of this 5 terminals are average occupancy, then 010-6888999 terminal Upstream bandwidth and downlink bandwidth are respectively 50M, and 028-3335558 terminal uplink bandwidth and downlink bandwidth are respectively 40M, 0990- 9998889 terminal uplink bandwidth and downlink bandwidth are respectively 30M, 026-5479431 terminal uplink bandwidth and downlink bandwidth difference For 35M, 030-1578459 terminal uplink bandwidth and downlink bandwidth are respectively 30M.
