Embodiment
In cdma2000 1x system,, four kinds of channel speed types are arranged, i.e. rate1, rate1/2, rate1/4 and rate1/8 for primary channel.The channel spread spectrum gain and the channel speed of primary channel are inversely proportional to, and promptly channel speed is low more, and spreading gain is high more, and like this, it is also just low more to reach the power that same frame error rate needs.
In common channel model, channel speed is 1/2 of rate1 for the rate1/2 power demand, and channel speed is that rate1/4 and rate1/8 power demand are respectively 1/4 and 1/8 of rate1.
At present, three kinds of general speech business coding EVRC (Enhanced Variable Rate Codec, enhancement mode variable Rate audio coder ﹠ decoder (codec)), 8K QCELP (Qualcomm Code Excited LinearPrediction 8K, high pass Code Excited Linear Prediction 8K audio coder ﹠ decoder (codec)) and 13K QCELP (Qualcomm Code Excited Linear Prediction 13K, high pass Code Excited Linear Prediction 13K audio coder ﹠ decoder (codec)) 5 kinds of reduction of speed rate patterns are all arranged.But corresponding to different codings, the meaning of every kind of reduction of speed rate pattern is different, and five kinds of reduction of speed rate pattern corresponding codes speed ratio examples of EVRC coding are as shown in table 1:
Table 1
| Reduction of speed rate coding mode | The full-rate vocoding ratio | The full-rate vocoding reduction of speed is 1/2 |
| 0 | 1 | 0 |
| 1 | 3/4 | 1/4 |
| 2 | 1/2 | 1/2 |
| 3 | 1/4 | 3/4 |
| 4 | 0 | 1 |
In the table 1, five values of first row are corresponding one by one with five kinds of reduction of speed rate patterns, and wherein ' 000 ' is mode0, and this reduction of speed rate pattern can not be converted to half rate frame with speech frame; ' 001 ' is mode1, and this reduction of speed rate pattern can be converted to half rate frame with 1/4 in all speech frames in the voice sequence; ' 010 ' is mode2, and this reduction of speed rate pattern can be converted to half rate frame with 1/2 in all speech frames in the voice sequence; ' 011 ' is mode3, and this reduction of speed rate pattern can be converted to half rate frame with 3/4 in the speech frame in the voice sequence; ' 100 ' is mode4, and this reduction of speed rate pattern can be converted to half rate frame with full-rate vocodings all in the voice sequence.
Five kinds of reduction of speed rate pattern corresponding codes speed ratio examples of 8K QCELP coding are as shown in table 2.
Table 2
| Reduction of speed rate coding mode | The full-rate vocoding ratio | The full-rate vocoding reduction of speed is 1/2 |
| 0 | 1 | 0 |
| 1 | 3/4 | 1/4 |
| 2 | 1/2 | 1/2 |
| 3 | 1/4 | 3/4 |
| 4 | 0 | 1 |
The implication of five kinds of reduction of speed rate patterns of EVRC coding is identical in the implication of five kinds of reduction of speed rate patterns of the 8K QCELP coding shown in the table 2 and the table 1.
Five kinds of reduction of speed rate pattern corresponding codes speed ratio examples of 13K QCELP coding are as shown in table 3.
Table 3
| Reduction of speed rate coding mode | The full-rate vocoding ratio | The full-rate vocoding reduction of speed is 1/2 rate frame ratio | The full-rate vocoding reduction of speed is 1/4 |
| 0 | 1 | 0 | 0 |
| 1 | 0.7 | 0.3 | 0 |
| 2 | 0.7 | 0 | 0.3 |
| 3 | 0.4 | 0.3 | 0.3 |
| 4 | 0 | 1 | 0 |
The implication of five kinds of reduction of speed rate patterns of EVRC coding is roughly the same in the implication of five kinds of reduction of speed rate patterns of the 13K QCELP coding shown in the table 3 and the table 1, and just 13K QCELP coding can be changed full-rate vocoding 1/2 and 1/4 two type rate frame.
The different rates pattern of above-mentioned coding is different to the influence of system loading, and the different rates pattern that coding is described with concrete result of the test is to the influence of system loading and to the influence of the voice quality of conversation below.
Be set in the process of the test, use the multi-section portable terminal to dial mutually, and after connection, carry out playback for the both call sides playing back music or for both call sides, to simulate true conversation, with the EVRC voice coding modes is example, in descending pattern 0, pattern 1, pattern 2, mode 3 and the pattern 4 of adopting respectively of conversation, the forward emitting power and the voice quality of coming accounting base-station.
Based on the test result of the forward emitting power of the base station of different speech coding reduction of speed rate pattern as shown in Figure 3.
As can be seen from Figure 3, when descending the employings mode0 of conversation, the forward direction of system is loaded basicly stable between 66%～68%; When descending the employings mode1 of conversation, the forward direction of system is loaded basicly stable between 63%～65%; When descending the employings mode2 of conversation, the forward direction of system is loaded basicly stable between 59%～60%; When descending the employings mode3 of conversation, the forward direction of system is loaded basicly stable between 55%～56%; When descending the employings mode4 of conversation, the forward direction of system is loaded basicly stable between 51%～52%.
The test result of voice quality is shown in accompanying drawing 4 and accompanying drawing 5.
Fig. 4 is the voice quality test result that adopts PESQ-LQ speech assessment standard to obtain, Fig. 5 is artificial voice quality test result, in this test, 10 personal accomplishment testees have been chosen, and, carry out the voice quality scoring according to personal feeling by this 10 testee to this 10 testees playback simultaneously.
As can be seen from Figure 4, when speech coding reduction of speed rate pattern during from mode0 to mode4, voice quality is also descending gradually.
As can be seen from Figure 5, these two kinds of speech coding reduction of speed rate patterns of MODE0 and MODE1 are on voice quality, and more difficult discrimination goes out which is good and which is bad; Equally, these two kinds of speech coding reduction of speed rate patterns of MODE2 and MODE3 are very approaching on voice quality.The voice quality of the voice quality of MODE4 correspondence and other speech coding reduction of speed rate pattern correspondences differs greatly, and tested personnel are easy to the voice quality of the voice quality of MODE4 correspondence and other four kinds of speech coding reduction of speed rate pattern correspondences is distinguished.
Reflect according to the testee: the voice under these two kinds of speech coding reduction of speed rate patterns of MODE2, MODE3 have a distortion, still, can more clearly not hear the content of voice.Voice distortion under the MODE4 speech coding reduction of speed rate pattern is comparatively obvious, still, can catch the content of voice.
From top test result as can be known, when system loading is very high, suitably adjust the code rate of the frame in the downlink voice sequence of conversing, it is the reduction of speed rate pattern of the speech coding of suitable adjustment conversation, be adjusted into pattern 2 or mode 3 as the reduction of speed rate pattern 1 of speech coding that will conversation, can when not causing voice quality obviously to descend, comparatively significantly save the forward emitting power of system, thereby effectively reduce the forward direction load of system.
Control method below in conjunction with 6 pairs of system forward loads provided by the invention of accompanying drawing is elaborated.
Among Fig. 6, in step 600, the forward direction of detection system load.The present invention does not limit the method for detection system forward direction load, promptly can use existing method to come the forward direction load of detection system.
To step 610, judge that the forward direction load of system and THRESHOLD_FWD_LOAD_HIGH are that the size of predetermined control thresholding one, the forward direction load of system are the size of predetermined control thresholding two with THRESHOLD_FWD_LOAD_LOW.THRESHOLD_FWD_LOAD_HIGH is used for determining whether the forward direction load of system is too high.THRESHOLD_FWD_LOAD_LOW is used for determining whether the forward direction load of system drops to safe load.The value of the THRESHOLD_FWD_LOAD_HIGH here should be not less than the value of THRESHOLD_FWD_LOAD_LOW, and these two values should be provided with according to the actual conditions of system.
Load when being higher than THRESHOLD_FWD_LOAD_HIGH if determine the forward direction of system,, reduce the code rate of the frame in the current downlink voice sequence of conversation to step 620.The code rate that reduces the frame in the current downlink voice sequence of conversation can realize by the reduction of speed rate pattern of adjusting the current speech coding of conversation.When reducing the code rate of the frame in the current downlink voice sequence of conversation, should under the prerequisite that guarantees voice quality, suitably reduce the code rate of the frame in the current downlink voice sequence of conversation.When adjusting the reduction of speed rate pattern of the speech coding of conversing, can carry out according to predetermined policy one.
Predetermined policy one specifically comprises following content:
1, for VIP user, the voice quality that guarantee its conversation is best, so, to the reduction of speed rate pattern 0 that VIP user should use speech coding all the time, promptly VIP user is not carried out the reduction of speed rate and handle.
2, for non-VIP user's domestic consumer, when adjusting the reduction of speed rate pattern of the current speech coding of conversation, can adopt following two kinds of methods to realize.
Method one: carry out the adjustment of the reduction of speed rate pattern of speech coding at the conversation of all domestic consumers.
Method two: carry out the adjustment of the reduction of speed rate pattern of speech coding at the conversation of part domestic consumer, as only adjusting the new reduction of speed rate pattern that inserts the speech coding of calling out, like this, after existing conversation all discharged, the reduction of speed rate pattern of the speech coding of all conversations had all obtained change.
The adjustment mode of method two relatively relaxes, and can not cause the user in the process that receives calls, and feels the unexpected decline of call voice quality.The adjustment mode of method one can be alleviated the forward direction load of system fast, reach the effect of getting instant result, thereby the forward direction of mitigation system is loaded rapidly.
3, the method for adjusting the reduction of speed rate pattern of the current speech coding of domestic consumer's conversation is: if the reduction of speed rate pattern of the current speech coding of conversing is MODE0, then the MODE0 that will converse is adjusted into MODE1; The reduction of speed rate pattern of current speech coding is MODE1 if converse, and then the MODE1 that will converse is adjusted into MODE2; The reduction of speed rate pattern of current speech coding is MODE2 if converse, and then the MODE2 that will converse is adjusted into MODE3.
4, because MODE4 has tangible voice distortion phenomenon, so at any time, the reduction of speed rate mode adjustment of the current speech coding of all will not conversing is MODE4.
After the frame code rate of system in the downlink voice sequence of having adjusted conversation according to predetermined policy one, to step 640, this system forward load control procedure finishes, when needs carry out system forward load control next time, to step 600.
In step 610,,, improve the code rate of the frame in the current downlink voice sequence of conversation to step 630 if the forward direction of above-mentioned detected system is loaded when being lower than THRESHOLD_FWD_LOAD_LOW.The code rate that improves the frame in the current downlink voice sequence of conversation can realize by the reduction of speed rate pattern of adjusting the current speech coding of conversation.When adjusting the reduction of speed rate pattern of the current speech coding of conversation, can carry out according to predetermined policy two.
Predetermined policy two specifically comprises following content:
1, for VIP user, the voice quality that guarantee its conversation is best, so, to the reduction of speed rate pattern 0 that VIP user should use speech coding all the time, promptly VIP user is not carried out the speed adjustment.
2, for non-VIP user's domestic consumer, when adjusting the reduction of speed rate pattern of the current speech coding of conversation, can adopt following two kinds of methods to realize.
Method one: carry out the adjustment of the reduction of speed rate pattern of speech coding at the conversation of all domestic consumers.
Method two: carry out the adjustment of the reduction of speed rate pattern of speech coding at the conversation of part domestic consumer, as only adjusting the new reduction of speed rate pattern that inserts the speech coding of calling out, like this, after existing conversation all discharged, the reduction of speed rate pattern of the speech coding of all conversations had all obtained change.
The adjustment mode of method two relatively relaxes, and can not cause the forward direction load of system to increase sharply.In predetermined policy two, the present invention advises adopting the adjustment mode of method two.
3, the method for adjusting the reduction of speed rate pattern of the current speech coding of domestic consumer's conversation is: if the reduction of speed rate pattern of the current speech coding of conversing is MODE1, then the MODE1 that will converse is adjusted into MODE0; The reduction of speed rate pattern of current speech coding is MODE2 if converse, and then the MODE2 that will converse is adjusted into MODE1; The reduction of speed rate pattern of current speech coding is MODE3 if converse, and then the MODE3 that will converse is adjusted into MODE2.
4, because MODE4 has tangible voice distortion phenomenon, so at any time, the reduction of speed rate mode adjustment of the current speech coding of all will not conversing is MODE4.
After the frame code rate of system in the downlink voice sequence of having adjusted conversation according to predetermined policy two, to step 640, this system forward load control procedure finishes, when needs carry out system forward load control next time, to step 600.
In step 610, if the forward direction of above-mentioned detected system load is between THRESHOLD_FWD_LOAD_HIGH and THRESHOLD_FWD_LOAD_LOW, be that the forward direction load that the forward direction load of system is not higher than THRESHOLD_FWD_LOAD_HIGH and system also is not less than THRESHOLD_FWD_LOAD_LOW, then arrive step 640, this system forward load control procedure finishes, when needs carry out system forward load control next time, to step 600.
