In this step, can be specifically the channel quality assessment result according to up channel obtain voice
Evaluation the quality result, it is also possible to which channel quality assessment result according to down channel obtains speech business
Quality assessment result, can be with up channel and the channel quality assessment result of down channel.
In above-mentioned steps S101, when the channel for being used includes up channel, assessment terminal is carried out currently
Speech business obtain channel quality assessment result using the present channel quality of channel and include：Obtain up letter
The current Signal to Interference plus Noise Ratio value in road, current Signal to Interference plus Noise Ratio value is compared with default up condition and obtains up letter
Road quality assessment result.It is, of course, also possible to just carry out the channel quality of up channel with other modes comment
Estimate.
Commented specifically, current Signal to Interference plus Noise Ratio value and default up condition being compared and obtaining uplink signal-channel quality
Estimating result includes：Judge current Signal to Interference plus Noise Ratio value whether more than or equal to default first up Signal to Interference plus Noise Ratio threshold value；
In this way, then assessment uplink signal-channel quality assessment result is the first up assessment result；Judge current Signal to Interference plus Noise Ratio
Whether value is less than or equal to default second up Signal to Interference plus Noise Ratio threshold value；In this way, then assessment uplink signal-channel quality assessment
Result is the second up assessment result；Judge whether current Signal to Interference plus Noise Ratio value is dry less than the default first up letter to make an uproar
Than threshold value and more than default second up Signal to Interference plus Noise Ratio threshold value；In this way, then the assessment of assessment uplink signal-channel quality is tied
Fruit is a preceding uplink signal-channel quality assessment result.
It is SINR thresholdings higher with default first up Signal to Interference plus Noise Ratio threshold value, presets the second up Signal to Interference plus Noise Ratio
Threshold value is relatively low SINR thresholdings, and the first up assessment result is that uplink signal-channel quality is " good ", on second
Row assessment result is uplink signal-channel quality to be illustrated as a example by " poor "：SINR (Single based on user terminal
To Interference plus Noise Ratio Signal to Interference plus Noise Ratio) judge, SINR is in a voice quality
Calculated using filtering mode in the judgement cycle, i.e. user terminal gives the correct time on for the first time, and SINR is currency；
Hereafter, SINR is the current SINR of (1-a) * history SINR+a*, and wherein a is filtering factor.Two
SINR thresholdings, a SINR thresholding higher, a relatively low SINR thresholding.Arrived when the voice judgement cycle
When, the SINR value and SINR thresholdings for calculating compare：If calculating SINR value more than or equal to SINR high
Thresholding, then judge that uplink signal-channel quality is " good "；If the SINR value for calculating is less than or equal to low SINR
Thresholding, then judge that uplink signal-channel quality is " poor "；If the SINR value for calculating in SINR thresholdings high and
Between low SINR thresholdings, then maintain the uplink signal-channel quality of previous judgement constant, if judging for the first time,
Previous uplink signal-channel quality is given tacit consent to for " good ".
In above-mentioned steps S101, when the channel for being used includes down channel, assessment terminal is carried out currently

The current Block Error Rate value and current modulation coding mode value in road, by current Block Error Rate value and current modulating-coding side
Formula value is compared with default downstream conditions and obtains down channel quality assessment result.It is, of course, also possible to just use
Other modes carry out the channel quality assessment of down channel.
Specifically, current Block Error Rate value and current modulation coding mode value are compared with default downstream conditions
Obtaining down channel quality assessment result includes：Judge current modulation coding mode value whether more than or equal to default
First downlink modulation coding mode threshold value；In this way, current Block Error Rate value is entered with default descending Block Error Rate threshold value
Row compares, and such as comparative result is that current Block Error Rate value is less than default descending Block Error Rate threshold value, assesses down channel
Quality assessment result is the first descending assessment result；As comparative result is default for current Block Error Rate value is more than or equal to
Descending Block Error Rate threshold value, then it is that a preceding down channel quality assesses knot to assess down channel quality assessment result
Really；Judge current modulation coding mode value whether less than or equal to default second downlink modulation coding mode threshold value；
In this way, current Block Error Rate value is compared with default descending Block Error Rate threshold value, such as comparative result is missed for current
Block rate value is more than or equal to presets descending Block Error Rate threshold value, and assessment down channel quality assessment result is second descending
Assessment result；If comparative result is that current Block Error Rate value is less than default descending Block Error Rate threshold value, then before being evaluated as
Down channel quality assessment result；Judge whether current modulation coding mode value is descending more than default second
Modulation coding mode threshold value and less than default first downlink modulation coding mode threshold value；In this way, then assess descending
Channel quality assessment result is a preceding down channel quality assessment result.
It is MCS thresholdings higher with default first downlink modulation coding mode threshold value, presets the second Corticofugal Modulation of Somatosensory
Coded system threshold value is relatively low MCS thresholdings, and it is descending BLER thresholdings, first to preset descending Block Error Rate threshold value
Descending assessment result is down channel quality to be illustrated as a example by " good "：Descending BLER based on user terminal
(Block error rate, Block Error Rate) and descending MCS (Modulation and Coding Scheme,
Modulation coding mode) judge.Descending BLER a voice quality judge in the cycle calculation as：(NACK
Number/scheduling total degree) * 100%.Descending MCS uses arithmetic average within a voice quality judgement cycle
Mode is calculated, i.e., then, it is all descending scheduling MCS in the cycle to calculate final descending MCS value to periodic point
Arithmetic mean of instantaneous value.One descending BLER thresholding, two descending MCS thresholdings, a MCS thresholding higher,
One relatively low MCS thresholding.When the voice judgement cycle then, the descending MCS value for calculating and descending MCS
Thresholding compares：If calculating descending MCS value more than or equal to descending MCS high thresholds, further, compare
The descending BLER values for calculating and descending BLER thresholdings：If descending BLER is less than descending BLER thresholdings,
Then judge that down channel quality is " good "；If descending BLER is more than or equal to descending BLER thresholdings, tie up
The down channel quality for holding previous judgement is constant, if judging for the first time, gives tacit consent to previous down channel quality
For " good ".If the descending MCS value for calculating is less than or equal to descending MCS low thresholds, further, than
The descending BLER values for relatively calculating and descending BLER thresholdings：If descending BLER is more than or equal to descending BLER
Thresholding, then judge that down channel quality is " poor "；If descending BLER is less than descending BLER thresholdings,
Maintain the down channel quality of previous judgement constant.If the descending MCS value for calculating is in descending MCS wealthy families
Between limit and descending MCS low thresholds, then maintain the down channel quality of previous judgement constant.
In above-mentioned steps S102, the speech service quality according to channel quality assessment outcome evaluation terminal is obtained
Speech service quality assessment result includes：When the channel for being used includes up channel, such as up channel matter
Amount assessment result is the first up assessment result, then it is the first voice industry to assess speech service quality assessment result
Business quality assessment result；During such as up channel quality assessment result for the second up assessment result, then language is assessed
Sound business quality assessment result is the second speech service quality assessment result；When the channel for being used is including descending
During channel, such as descending channel quality assessment result is the first descending assessment result, then assess speech service quality
Assessment result is the first speech service quality assessment result；If descending channel quality assessment result is second descending
During assessment result, then it is the second speech service quality assessment result to assess speech service quality assessment result；When
When the channel for being used includes up channel and down channel, such as up channel quality assessment result is on first
Row assessment result, and down channel quality assessment result is the first descending assessment result, then assess speech business
Quality assessment result is the first speech service quality assessment result；Otherwise, then assessment speech service quality assessment
Result is the second speech service quality assessment result.Certainly, in order to improve the accuracy of assessment result, preferably
Selection include that up channel and down channel are estimated with the channel that is used.Enter with reference to above example
Row explanation, if the uplink wireless channel quality and downlink wireless channel quality of user terminal are " good ",
Then the voice quality of user terminal is " good "；If the uplink wireless channel quality and descending nothing of user terminal
One of line channel quality is " poor ", then the voice quality of user terminal is " poor ".
Embodiment two：
The terminal speech service switching management method of the present embodiment, as shown in Fig. 2 the method includes：
Step S201：Current voice service quality evaluation knot is obtained according to terminal speech evaluation the quality method
Really；
In this step, current language is obtained here according to the terminal speech evaluation the quality method implemented in
Sound business quality assessment result；Here what is obtained can be the first speech service quality assessment result, it is also possible to
It is the second speech service quality assessment result.
Step S202：Terminal speech service switching management is carried out according to current voice service quality assessment result.
In this step, terminal speech service switching management includes：Single wireless voice calling continuity switches
Or alien frequencies switching.
In above-mentioned steps S202, terminal speech business is carried out according to current voice service quality assessment result
Handover management includes：
Current voice service quality assessment result is the second speech service quality assessment result, an and preceding voice
When evaluation the quality result is the first speech service quality assessment result, then triggering terminal speech business switching
Management；
Current voice service quality assessment result is the first speech service quality assessment result, an and preceding voice
Evaluation the quality result is the second speech service quality assessment result, and is carrying out terminal speech business
During handover management, then stop the terminal speech service switching management for carrying out.
It is illustrated in conjunction with the embodiments, it is first determined whether reaching voice quality judges periodic point, voice
Quality takes continuous cycles detection mode, and voice user's terminal up-downgoing quality of wireless channel is entered within the cycle
Row monitoring statisticss；When reaching periodic point, flow is adjudicated into voice quality：According in the user terminal cycle
Up channel statistical information judges UE uplink signal-channel qualities, is recorded as " good " or " poor "；According to user
Down channel statistical information judges UE down channel qualities in the terminal cycle, is recorded as " good " or " poor "；
Then, according to the voice quality situation in the user terminal previous cycle, into different handling processes (such as
Really the cycle is first voice quality judgement cycle of user terminal, and the initial speech quality of user terminal is write from memory
Think " good ")：Voice quality before the user terminal is " good "：Current period user is judged again
The uplink signal-channel quality and down channel quality of terminal whether one of be " poor ", as long as up-downgoing channel quality
It is " poor " to have at least one, then mark the user terminal voice quality for " poor ", and base station side is to the use
Family terminal starts switching or SRVCC flows；If user terminal up-downgoing channel quality is not " poor ",
It is that " good " is constant to maintain the user terminal voice quality.Voice quality before the user terminal is " poor "：
Judge whether the uplink signal-channel quality and down channel quality of current period user terminal are " good " again,
If up-downgoing channel quality is all good, mark the user terminal voice quality for " good ", terminate user's end
Rectify in waiting switching or SRVCC flows；If one of user terminal up-downgoing channel quality is
" poor ", it is that " poor " is constant to maintain the user terminal voice quality.The user terminal is judging voice before
Quality has been started up switching or SRVCC flows when being " poor ", continue waiting for flow completion.
Being worth noting is, using speech service quality before the advanced trade of method in embodiment one in the present embodiment
The acquisition of assessment result, first, base station side firstly the need of voice user's terminal is identified, according to agreement, language
Sound business must be set up in the carrying of QCI (QoS Class Identifier, QoS grade designation)=1,
Therefore, if user terminal has the carrying of QCI=1, then it is assumed that user terminal is voice user's terminal, instead
It, it is believed that user terminal non-speech user terminal, below scheme only is performed to voice user's terminal；For knowing
The voice user's terminal not gone out, quality of wireless channel according to up-downgoing assesses voice quality, because voice
It is two-way, it is necessary to consider the quality of wireless channel of uplink and downlink simultaneously that business is related to uplink and downlink：If
The uplink wireless channel quality and downlink wireless channel quality of user terminal be " good ", then user terminal
Voice quality is " good "；If the uplink wireless channel quality and downlink wireless channel quality of user terminal its
One of be " poor ", then the voice quality of user terminal be " poor ".
Using the method for the present embodiment, base station eNodeB monitors the VoLTE up-downgoing voice qualities of UE, such as
Fruit voice quality difference then triggers alien frequencies switching or SRVCC flows, if it is decided that voice quality is recovered to threshold value,
Then terminate unfinished switching or SRVCC flows.So, when quality of wireless channel is deteriorated, can be timely
Voice user's terminal is switched to other networks, it is ensured that the high-quality voice experience of user terminal.
