Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only a real part of the invention
Example is applied, rather than whole embodiments.Below to the description reality of at least one exemplary embodiment
It is merely illustrative on border, never as to the present invention and its application or any limitation for using.
Based on the embodiment in the present invention, those of ordinary skill in the art are not before creative work is made
The every other embodiment for being obtained is put, the scope of protection of the invention is belonged to.
Be related to flow more long for voice rate Adjusted Option of the prior art, adjustment not enough and
When, it is difficult to the quick problem for following wireless channel situation of change to be adjusted, propose this programme.
Inventor has found the characteristic according to LTE (Long Term Evolution) technology, and voice rate is certain
When, uplink wireless channel deteriorates can be caused to transmit MCS of the VoP using more low order
(Modulation and Coding Scheme, modulation and coding strategy), causes indirectly
Row TTI occupancy liftings, and uplink wireless channel improvement can cause transmission voice packet using more
The MCS of high-order, causes up TTI occupancies reduction indirectly.Therefore, transmitting terminal can be with root
According to up TTI occupancies situation, whether assessment uplink wireless channel quality is fast with current speech
Rate is matched, and makes voice rate dynamically adjustment, and this adjustment is not due to being related to VoP
The feedback of receiving terminal, can more rapidly follow wireless channel situation of change to be adjusted.
One embodiment of the method for present invention adjustment voice rate is retouched with reference to Fig. 1
State.
Fig. 1 is the flow chart of method one embodiment of present invention adjustment voice rate.Such as Fig. 1 institutes
Show, the method for the embodiment includes：
Step S102, transmitting terminal is called by VoLTE and establishes call with receiving terminal, is set
Initial speech speed.
Step S104, transmitting terminal detects up TTI occupancies.
Wherein, transmitting terminal is according in the TTI quantity determination that speech data is transmitted in Preset Time
Row TTI occupancies.For example, i.e. 100 TTI in TTI=1ms, 100ms, for passing
The TTI quantity of sending voice data is 40, then TTI occupancies are exactly 40%.
Step S106, transmitting terminal dynamically adjusts voice rate according to up TTI occupancies.If
Up TTI occupancies illustrate to transmit MCS of the voice packet using higher order, indirectly than relatively low
Illustrate that uplink wireless channel improves, therefore voice rate can be lifted, whereas if up TTI
Occupancy is higher, can reduce voice rate.
Wherein, transmitting terminal adjusts voice rate by adjusting vocoder mode.It is right in VoLTE
In broadband voice, contain 0~8 and amount to 9 kinds of vocoder modes, that is, 9 kinds of voice speed
Rate grade；For narrowband speech, contain 0~7 and amount to 8 kinds of vocoder modes, that is, 8
Plant voice rate grade.Transmitting terminal for example can by reduce step by step vocoder mode grade come by
Voice rate is gradually reduced, so as to finally determine to be best suitable for the voice rate of current channel condition.Or
Person, if up TTI occupancies with expect thresholding gap than larger, it is also possible to increase sound
The adjustment amplitude of code device mode hierarchies, to increase the adjustment amplitude of voice rate.
Above method transmitting terminal is according to up TTI occupancies situation of change, dynamic adjustment voice speed
Rate, adjustment flow pertains only to transmitting terminal in itself, and the feedback procedure of receiving terminal is not related to, and adjustment is very fast,
Enable to voice rate and uplink wireless channel situation of change Rapid matching.
With reference to Fig. 2 to transmitting terminal how according to up TTI occupancies dynamic adjustment voice
Speed is described.In the present embodiment, there is provided the first thresholding and the second thresholding, right respectively
In requisition for the lower and upper limit of the up TTI occupancies of adjustment voice rate, as up TTI
Transmitting terminal improves voice rate when occupancy is less than the first thresholding, when up TTI occupancies are high
Transmitting terminal reduction voice rate when the second thresholding.
Fig. 2 is the flow chart of another embodiment of the method for present invention adjustment voice rate.Such as Fig. 2
Shown, this implementation is specifically included：
Step S202, transmitting terminal is called by VoLTE and establishes call with receiving terminal, is set
Initial speech speed.
Step S204, transmitting terminal detects whether up TTI occupancies are less than default first thresholding,
If it is, performing step S206, step S208. is otherwise performed
Step S206, transmitting terminal improves voice rate.
Step S208, transmitting terminal detects whether up TTI occupancies are higher than default second thresholding,
If it is, performing step S210, the adjustment of voice rate is not carried out otherwise.
Step S210, transmitting terminal reduction voice rate.
Wherein, the first thresholding is less than the second thresholding.First thresholding and the second thresholding for example can be with roots
Obtained according to test, by adjusting different parameter determinations so that the first optimal thresholding of voice quality
With the second thresholding.First thresholding and the second thresholding can be fixedly installed by transmitting terminal, or by base
Side stand by broadcasting to transmitting side terminal transmission threshold parameter, transmitting terminal is carried out according to network parameter
Configuration.
A kind of application scenarios：Terminal 1 is called by VoLTE and establishes call with terminal 2,
The initial pattern of vocoder be broadband voice pattern 8, that is, high definition voice flank speed pattern.
The first thresholding is set to 50% in network, and the second thresholding is set to 75%.The initial stage is set up in call,
Terminal 1 is in preferable signal environment, and up TTI occupancies are less than the first thresholding always.It is logical
During words, terminal 1 is moved to the environment of dtr signal, up TTI occupancies during this
Constantly raise, and more than the first thresholding.Terminal 1 continues to be moved to the worse environment of signal, should
During, terminal detects up TTI occupancies and continues to raise, and more than thresholding 2, terminal
The vocoder mode of transmission is reduced to broadband voice mode 7 by 1 from broadband speech pattern 8.Now,
Detected by terminal 1, up TTI occupancies are reduced to below the second thresholding, call continue into
OK.
The above method can in time adjust voice rate according to the situation of change of quality of wireless channel,
It is not related to receiving terminal according to the VoP situation for receiving, change voice is sent to transmitting terminal
The processes such as rate request.When channel quality is poor, voice rate is reduced, so as to reduce reception
The packet loss at end, when channel quality is preferable, improves voice rate, it is possible to use family obtains more preferable
Experience.
