Greatly.The first terminal described in embodiments of the present invention may refer to the process that second terminal sends encoding and decoding renegotiation request
Process in Fig. 1.
The embodiment of the present invention provides a kind of method for sending encoding and decoding renegotiation request, as shown in Figure 2, comprising:
S101, first terminal monitor the uplink available bandwidth and downlink available bandwidth of the serving cell of the first terminal.
Specifically, terminal can for mobile phone, tablet computer or other may be implemented to carry out video calling between communicating pair
Or the equipment of voice communication.
S102, it is less than preset threshold and the duration is more than when the uplink available bandwidth or the downlink available bandwidth
When preset time period, the first terminal according to the average value of uplink available bandwidth described in the preset time period and it is described under
The average value of row available bandwidth determines the first duration, is described the at the time of indicated by the sum of current time and first duration
One terminal sends the moment the latest of encoding and decoding renegotiation request to second terminal, and the preset threshold is the first terminal and institute
State the voice communication that second terminal currently carries out or the bandwidth value that video calling needs.
It wherein, is 720 pixel/inch (pixels per inch, abbreviation ppi), the video that frame per second is 30 for resolution ratio
Call, required bandwidth is about 2.4M bps (bits per second, abbreviation bps)；Resolution ratio is 640p, and frame per second is 30
Video calling, required bandwidth are about 1.6Mbps；Resolution ratio is 640p, the video calling that frame per second is 15, and required bandwidth is about
0.9Mbps.Use adaptive multi-rate broadband coding (Adaptive Multi-rate-Wideband, AMR-WB) 23.85k's
The voice communication that coding mode carries out, required bandwidth is about 50kbps.
Specifically, can determine the first duration by following two mode.
Mode one, the first terminal are according to T1=W [1+ (1-S/Y) A1+(1-X/Y)·A2] determine the first duration,
Wherein, T1For the first duration, W is preset duration, and S is the average value of the uplink available bandwidth in the preset time period, and X is
The average value of the downlink available bandwidth in the preset time period, Y are the preset threshold, A1And A2For regulatory factor, T1、
W、S、X、Y、A1And A2It is positive number.
Mode two, the first terminal are according to T1=W [1+ (1-S/Y) A1+(1-X/Y)·A2+ F] when determining first
It is long, wherein T1For the first duration, W is preset duration, and S is the average value of the uplink available bandwidth in the preset time period,
X is the average value of the downlink available bandwidth in the preset time period, and Y is the preset threshold, A1And A2For regulatory factor, F
The number for continuously transmitting the encoding and decoding renegotiation request failure for the first terminal apart from the current time recently,
T1、W、S、X、Y、A1And A2It is positive number, F is the integer more than or equal to 0.
In mode one and mode two, W is preset duration, can specifically be provided by manufacturer terminal or network operator,
A1And A2Also be preset value, specifically can according to actual application scenarios determine, F be the first terminal apart from it is described current when
The nearest number for continuously transmitting the encoding and decoding renegotiation request failure is carved, illustratively, if before current time, first
Terminal has sent 5 encoding and decoding renegotiation requests to second terminal, wherein fail for 5 times, then F=5, if in 5 times the 4th at
Function the 5th fails, then F=1, if the 5th success, F=0 in 5 times.
Wherein, the value of W can process performance based on the equipment in IMS network, network congestion when highest encoding and decoding assist again
Quotient's number of request etc. is determined.For example, illustrating the equipment in IMS network when the process performance of the equipment in IMS network is preferable
More encoding and decoding renegotiation request can be handled simultaneously, then the value of W can be set less than normal, and otherwise, the value of W can be set
It is bigger than normal.The value of preset time period can based on user behavior analysis (such as user it is interrupted to poor video quality, voice when enduring
It is long) it is determined.For example, when user to poor video quality endure duration it is longer when, preset time period can be arranged partially
Greatly, otherwise, preset time period can be arranged less than normal.Likewise, A1And A2Value may be based on equipment process performance, user
Behavioural analysis is determined.
In mode one and mode two, the value of S, X is lower or the value of F is bigger, T1Value it is bigger, since the value of S, X are lower
Or F value it is bigger when, illustrate that network condition is poorer, at this time each terminal should not within a short period simultaneously send disappear
Breath, and transmission encoding and decoding renegotiation request that should be in a longer time section successively, therefore, this method can be according to working as
Preceding network condition adjustment terminal sends the length of the period of encoding and decoding renegotiation request.
S103, the first terminal determine the second duration at random in first duration.
Specifically, first terminal can determine the second duration using random algorithm at random in the first duration.
S104, the first terminal send the encoding and decoding to the second terminal according to second duration to be negotiated to ask again
It asks.
Since the second duration is determined at random in the first duration, the encoding and decoding that each terminal is sent are negotiated again
The time of request is generally all different, therefore, can solve a large amount of terminal and sends encoding and decoding renegotiation request to IMS network simultaneously
Problem to cause the equipment processing pressure in IMS network excessive.
Specifically, the encoding and decoding renegotiation request that first terminal is sent to second terminal with second terminal for renegotiating
The resolution ratio and/or frame per second (or coding mode of voice communication) of video calling, for example, if first terminal starts to carry out resolution ratio

When 2.4Mbps, illustrate that the uplink available bandwidth of the serving cell of first terminal or downlink available bandwidth can not meet first eventually
End and second terminal video calling, at this point, first terminal can to second terminal send encoding and decoding renegotiation request, by with
Second terminal negotiates to carry out a resolution ratio and/or the lower video calling of frame per second again.
Specifically, S104 can specifically be realized in specific implementation by following 2 kinds of modes.
Mode 1, the first terminal are in T0+ P sends the encoding and decoding renegotiation request to the second terminal, wherein T0
For the current time, P is second duration.
Mode 2, the first terminal are in T0+ P/ (F+1) Xiang Suoshu second terminal sends the encoding and decoding renegotiation request,
Wherein, T0For the current time, P is second duration.
In mode 2, if the value of F is bigger, illustrate that first terminal repeatedly sends encoding and decoding renegotiation request not successfully,
Should then it allow first terminal in T1It is sent as early as possible in period, thus the second duration P calculated at random divided by failure time
Number, to reduce the waiting time that first terminal sends encoding and decoding renegotiation request.In addition, enabling F here since the value of F can be 0
It is preceded by 1 and does divisor again, avoid for the first time when calculating, the case where value of F is 0.

S101 is returned to step after executing step S105 (1).
S106 (1), the first terminal determine before current time and when apart from the current time nearest default
Between the serving cell in section the average value of uplink available bandwidth or the downlink available bandwidth of the serving cell be averaged
Whether value is less than Y.
If so, illustrating that the uplink available bandwidth of the serving cell of first terminal or downlink available bandwidth are not able to satisfy first eventually
End and the current video calling of second terminal or the demand of voice communication execute step S106 (1) return step S102 afterwards, if
It is no, illustrate that the uplink available bandwidth of the serving cell of first terminal and downlink available bandwidth are able to satisfy first terminal and second eventually
The demand of current video calling or voice communication is held, step S106 (1) return step S101 afterwards is executed.
If first terminal employing mode two determines that the first duration or employing mode 2 send encoding and decoding renegotiation request, such as
Shown in Fig. 4, after step s 104, the method also includes S105 (2) to S108 (2).
If the first terminal sends the encoding and decoding renegotiation request to the second terminal according to second duration
Success (be denoted as in Fig. 4 condition establishment) executes step S105 (2), if the first terminal is according to second duration to described
Second terminal sends the encoding and decoding renegotiation request failure (it is invalid that condition is denoted as in Fig. 4), executes step S106 (2).
F is reset to 0 by S105 (2), the first terminal, and Y is reset to the first terminal and the second terminal is compiled
The bandwidth value that the voice communication or video calling that decoding carries out negotiate again after need.
S101 is returned to step after executing step S105 (2).
S106 (2), the first terminal determine before current time and when apart from the current time nearest default
Between the serving cell in section the average value of uplink available bandwidth or the downlink available bandwidth of the serving cell be averaged
Whether value is less than Y.
If so, illustrating that the uplink available bandwidth of the serving cell of first terminal or downlink available bandwidth are not able to satisfy first eventually
End and the current video calling of second terminal or the demand of voice communication, execute step S107 (2)；If it is not, illustrating first terminal
Serving cell uplink available bandwidth and downlink available bandwidth is able to satisfy first terminal and the current video of second terminal is logical
Words or the demand of voice communication, execute step S108 (2).
The value of F is increased by 1 by S107 (2), the first terminal.
Execute step S107 (2) return step S102 afterwards.
F is reset to 0 by S108 (2), the first terminal.
Execute step S108 (2) return step S101 afterwards.
