Measurement of the second measure the cycle that number quality level is more matched to carry out mean BEP is reported.
The above embodiment of the present invention changes the mode of traditional fixation measuring periodic report mean BEP, according to nothing
Thread environment changes, dynamic self-adapting BEP measure the cycles, meets user's movement or wireless environment is quick
The data transfer demands that change brings；Specifically, the page-downloading that application layer browses class can effectively be improved
Speed, wireless single channel time slot throughput, descending retransmission rate and high-order coding accounting.
Further, also include in 11 as described before acquisition methods of above-mentioned steps in another embodiment of the present invention：
Step 14, sends data wireless links block to terminal unit according to the first coded system；Its first coding
Mode is pre-set for network side, and base station controller BSC passes through the first coded system for pre-setting to end
End equipment sends data wireless links block；
Step 15, the ratio of the current radio link data block that receiving terminal apparatus are reported in the first measure the cycle
The bit error rate standard of bit error arithmetic mean of instantaneous value (i.e. mean BEP) and current radio link data block
Variance yields (i.e. cv BEP)；When the first measure the cycle arrives, such as the first measure the cycle be 3min, base
Station control BSC is sent after data wireless links block 3min to terminal unit, and terminal unit is to base during 3min
The mean BEP and cv BEP of the data wireless links block that station control sends are measured and are reported.
Step 16, according to bit error rate arithmetic mean of instantaneous value and bit error rate standard deviation square value, it is determined that and institute
The second coded system of current radio link data Block- matching is stated, and using second coded system to terminal
Equipment sends data wireless links block.Base station controller BSC according to mean BEP and cv BEP, by looking into
Ask BEP tables and find coded system corresponding with current radio link data block, i.e. the second coded system；Need
Illustrate, the first coded system is may be the same or different with the second coded system.Then in subsequent process, base
Station control is sent to terminal unit after encoding to data wireless links block using the second coded system.
It should be noted that, above-mentioned steps 14 to step 16 are transmitted across for the downlink data block of terminal unit
Journey；Number is sent to base station controller for the transmission process of the uplink data block of terminal unit, i.e. terminal unit
According to block process approximately as：Base station controller is by data uplink resource allocating message the coding staff given tacit consent to
Formula tells that terminal unit, terminal unit send data block to base station controller according to the coded system of acquiescence, when
When first measure the cycle arrives, the current radio link data block that base station controller is sent to terminal unit
Mean BEP and cv BEP are measured, and it is corresponding with current radio link data block to search the determination of BEP tables
Coded system, then the coded system of determination is sent to into terminal unit by up confirmation message, then terminal
Equipment is encoded to data block according to new coded system and is sent to base station controller.
In the above embodiment of the present invention, entered by the up process and descending process to data wireless links block
The concrete restriction of row causes the implementation of the present invention more to enrich and complete.
Further, as shown in figure 4, step 12 includes in the above embodiment of the present invention：
Step 121, multiple bit error rate arithmetic mean of instantaneous values is compared with a predetermined threshold value, is obtained
To a comparative result；The setting of its predetermined threshold value is related to wireless environment, typically may be configured as a marginal value,
That is mean BEP are more than the marginal value, show that wireless environment is preferable；Mean BEP are less than the marginal value, table
Bright wireless environment is poor.
Step 122, if the comparative result is preset more than described in showing multiple bit error rate arithmetic mean of instantaneous values
The number of the arithmetic mean of instantaneous value of threshold value is less than the first preset value, reduces first measure the cycle, obtains the
Two measure the cycles；In concrete application, cannot be accurate with the magnitude relationship of predetermined threshold value from a mean BEP
Judge current wireless environment, therefore be compared with predetermined threshold value using multiple mean BEP；And work as
Number in multiple mean BEP more than the predetermined threshold value is less than P1 (i.e. the first preset value), then illustrate
Current wireless environment is poor, then reduce the first measure the cycle and obtain the second measure the cycle；Make terminal more rapidly
Report wireless environment variation information so that terminal can adjust coded system in time, so as to lifted data biography
Defeated accuracy.
Step 123, if the comparative result is preset more than described in showing multiple bit error rate arithmetic mean of instantaneous values
The number of the arithmetic mean of instantaneous value of threshold value is more than the second preset value, increases first measure the cycle, obtains the
Two measure the cycles；Wherein, first preset value is less than or equal to the second preset value.In concrete application,
Current wireless environment cannot accurately be judged with the magnitude relationship of predetermined threshold value from a mean BEP,
Therefore be compared with predetermined threshold value using multiple mean BEP, and work as in multiple mean BEP more than described
The number of predetermined threshold value is more than P2 (i.e. the second preset value), then illustrate that current wireless environment preferably, then increases
Big first measure the cycle obtains the second measure the cycle；Terminal is made to reduce reporting the speed of radio environment information, eventually
Hold according to high coded system transmission data, so as to increase data transmission efficiency.
It should be noted that the first preset value is less than or equal to the second preset value；When the first preset value is equal to
During the second preset value, such as the first preset value is equal to the second preset value and is equal to 5, i.e., when more than predetermined threshold value
When the number of mean BEP is less than 5, reduces the first measure the cycle and obtain the second measure the cycle；When more than default
When the number of the mean BEP of threshold value is more than 5, the first measure the cycle of increase obtains the second measure the cycle；And
When the number of the mean BEP more than predetermined threshold value is equal to 5, can be arranged by pre-setting
Or increase the first measure the cycle in the case of this kind or reduce the first measure the cycle and keep the first measure the cycle not
Become, here is not especially limited.And situation of first preset value less than the second preset value is directed to, such as first
Preset value is 5, and the second preset value is 8, i.e., when the number of the mean BEP more than predetermined threshold value is less than 5
When, reduce the first measure the cycle and obtain the second measure the cycle；When more than predetermined threshold value mean BEP
When number is more than 8, the first measure the cycle of increase obtains the second measure the cycle；And when subtracting more than predetermined threshold value
Little first measure the cycle obtains the second measure the cycle；When the number of the mean BEP more than predetermined threshold value is more than
When 5, increase the first measure the cycle and the number of the second measure the cycle is obtained more than or equal to 5 and be less than or wait
When 8, the first measure the cycle is not adjusted, keeps the first measure the cycle constant, i.e., the second measurement week
Phase is equal to the first measure the cycle.
The determination method of the second measure the cycle is specifically described separately below：
Method one：For needing to reduce the situation of the first measure the cycle：
I.e. step 122 includes：
First measure the cycle is reduced the first step value, obtains the second measure the cycle by step 1221.Its
In, the first step value generally 1 or 2, i.e. the first measure the cycle reduces 1 unit value or 2 unit values；
The implication of its unit value is consistent with the unit of the first measure the cycle, and such as the first measure the cycle is 5min, then
Second measure the cycle=5min-1min/2min；Due to the unit of the first measure the cycle it is indefinite, as long as be the time
Unit just, therefore is also not construed as limiting to the unit of the first step value at this, the unit of its first step value and the
The unit of one measure the cycle is consistent.
Determined after the second measure the cycle using above-mentioned steps 1221, be there is also an issue, i.e., it is concrete for one
Service application, base station controller can arrange a minimum measure the cycle, if reducing what the first measure the cycle was obtained
Second measure the cycle is less than above-mentioned minimum measure the cycle, then the acquisition methods provided in an embodiment of the present invention are also
Including：
Step 1222, if first measure the cycle is less than the first predetermined period after reducing the first step value, really
Fixed second measure the cycle is first predetermined period.Wherein, the first predetermined period be it is above-mentioned most
Little measure the cycle, i.e., the measure the cycle for obtaining after the first measure the cycle reduces the first step value is less than minimum survey
The amount cycle, then using above-mentioned minimum measure the cycle as the second measure the cycle.
To sum up, the second measure the cycle=MAX { (first the-the first step value of measure the cycle), the first predetermined period }；
Then by upstream data, BSC confirms that the second measure the cycle is sent to terminal unit by message, works as terminal unit
After by the second measure the cycle, the measurement of follow-up wireless environment is carried out according to the second measure the cycle and reported.
Method two：For needing to increase the situation of the first measure the cycle：
I.e. step 123 includes：
First measure the cycle is increased the second step value, obtains the second measure the cycle by step 1231.Its
In, the second step value generally 1 or 2, i.e. the first measure the cycle increases 1 unit value or 2 unit values；
The implication of its unit value is consistent with the unit of the first measure the cycle, and such as the first measure the cycle is 5min, then
Second measure the cycle=5min+1min/2min；Due to the unit of the first measure the cycle it is indefinite, as long as be the time
Unit just, therefore is also not construed as limiting to the unit of the second step value at this, the unit of its second step value and the
The unit of one measure the cycle is consistent.
Determined after the second measure the cycle using above-mentioned steps 1231, be there is also an issue, i.e., it is concrete for one
Service application, base station controller can arrange a maximum measure the cycle, if what the first measure the cycle of increase was obtained
Second measure the cycle is more than above-mentioned maximum measure the cycle, then the acquisition methods provided in an embodiment of the present invention are also
Including：
Step 1232, if first measure the cycle is more than the second predetermined period after increasing by the second step value, really
Fixed second measure the cycle is second predetermined period.Wherein, the second predetermined period be it is above-mentioned most
Big measure the cycle, i.e., the measure the cycle for obtaining after the first measure the cycle increases by the second step value is more than maximum survey
The amount cycle, then using above-mentioned maximum measure the cycle as the second measure the cycle.
To sum up, the second measure the cycle=MIN { (first the+the first step value of measure the cycle), the second predetermined period }；
Then by upstream data, BSC confirms that the second measure the cycle is sent to terminal unit by message, works as terminal unit
After by the second measure the cycle, the measurement of follow-up wireless environment is carried out according to the second measure the cycle and reported.
The concrete steps of the acquisition methods of measure the cycle provided in an embodiment of the present invention are carried out with reference to Fig. 5

Coded system, and carry out data transmission.
Step 53, with the continuous transmission of data block, mean BEP of the base station controller according to terminal to report
Value, carries out new BEP measure the cycles and calculates：
If mean BEP values are more than acquiescence MEAN BEP in N number of mean BEP values of terminal to report
The number of value (being such as 26) is less than P1, then reduce BEP measure the cycles, make terminal quickly report wireless ring
Border change information, adjusts coded system in time, lifts data transfer accuracy；New BEP measure the cycles
=MAX { (last time BEP measure the cycle value-measure the cycle adjusting step), minimum BEP measure the cycles }, its
Middle BEP measure the cycles adjusting step is 1～2；
If mean BEP values are more than acquiescence mean BEP values in N number of mean BEP values of terminal to report
Number be more than P2, illustrate current radio environment preferably, then increases BEP measure the cycles, make in terminal reduction
The number of times of report radio environment information, according to high coded system transmission data, increases data transmission efficiency；New
BEP measure the cycles=MIN { survey by (last time BEP measure the cycle value+measure the cycle adjusting step), maximum BEP
The amount cycle }, wherein BEP measure the cycles adjusting step is 1～2；
If mean BEP values are more than acquiescence mean BEP values in N number of mean BEP values of terminal to report
Number be more than or equal to P1 and be less than or equal to P2, then be not adjusted；Wherein give tacit consent to MEAN
BEP values, minimum BEP measure the cycles, maximum BEP measure the cycles, BEP measure the cycle adjusting steps, N,
P1, P2 can be configured on base station controller, and P2>P1.
Step 54, confirms message (Packet uplink ack) by new BEP measuring terminals by upstream data
Terminal is carried to, after terminal unit receives new BEP measure the cycle values, according to new BEP measure the cycles
Carry out mean/cv BEP measurements to report.
To sum up, show to adjust using method provided in an embodiment of the present invention dynamic through substantial amounts of test data
