Specific embodiment
The embodiment of the present invention is described in further detail below by specific embodiment combination attached drawing.
Embodiment one:
During solving existing wireless link, there is no the management processes of base-band resource, lead to foundation
Virtual Radio Link excessively can not but carry out active release, influence the problem of normally foundation of new Radio Link, the present invention is real
It applies example and a kind of baseband resource managing method is provided.
Referring to Figure 1, the baseband resource managing method includes the following steps:
S11: current base-band resource utilization rate is obtained；
Baseband resource managing method provided by the present embodiment specifically can be applied in the baseband resource managing of base station, when
So also it can be applied in the example that other need to carry out baseband resource managing.It should be understood that a base station can make
Base-band resource is limited, therefore how to be reasonably extremely important using these base-band resources.In the present embodiment, lead to
It crosses and reasonable distribution is carried out to current base-band resource, is discharged to improve the utilization rate of base-band resource, to the virtual radio chain of foundation
The quantity or ratio of road and real Radio Link are controlled, and guarantee to reach well on user terminal access quantity and communication quality
Balance.It avoids limited base-band resource from arbitrarily being used, such as establishes excessive Virtual Radio Link, base-band resource is caused to occupy
It is higher, real Radio Link can not be normally accessed, to reduce the quantity that base station is currently accessed user terminal, reduces user's end
End is successfully accessed rate.
It should be understood that base-band resource is mainly used for establishing corresponding wireless communication link, wireless communication link is specific
Including Virtual Radio Link and real Radio Link.Specifically, referring to Fig. 2, such as in order to realize between user 21 and user 22
Voice communication, corresponding base station 23 establishes corresponding real Radio Link firstly the need of for user 21 and user 22, passes through foundation
The reality Radio Link be just able to achieve the normal voice between user 21 and user 22 call, it should be appreciated that corresponding nothing
It is usually to be issued by base station controller 24 that wired link, which establishes instruction, and base station controller 24 passes through demodulation process user 21 or user
22 requests sent judge the type of service of the request, such as connect judging that user 21 and user 22 need to realize to converse
When, real wireless link instruction is issued to relevant base station, the foundation of real Radio Link is realized by the base station, to realize
Call connection between user 21 and user 22.
During establishing real Radio Link, the base-band resource certain for the reality wireless link distribution is needed, wherein base
Band resource includes but is not limited to base band searching resource, base band demodulating resource, baseband channel resource, the number of users carried with base station
The utilization rate of the increase of amount, base-band resource necessarily increases, then remaining base-band resource is just reduced therewith.
S12: it when judging that the base-band resource utilization rate reaches preset utilization rate threshold value, obtains currently-established virtual
The ratio of the occupied base-band resource of Radio Link and the currently-established occupied base-band resource of real Radio Link；
Judge whether to reach preset utilization rate threshold value by the current base-band resource utilization rate of acquisition, if so, then obtaining
The current occupied base-band resource of Virtual Radio Link that base station has had built up and currently-established real Radio Link
The ratio of occupied base-band resource.In some instances, it obtains current base-band resource utilization rate and the ratio can be simultaneously
It carries out.
Preset utilization rate threshold value can be according to practical situations flexible setting, however it is not limited to some specific numerical value.
For example, preset utilization rate threshold value can be set to 50%, it that is to say that the base-band resource that the base station has currently used accounts for total base
50% with resource.It should be noted that in some specific examples, it can be according to a certain specific base-band resource utilization rate
It is calculated: for example by taking base band searching resource as an example, obtaining current base band searching resource utilization rate, judge the current base band search
Whether resource utilization reaches preset searching resource utilization rate threshold value.When base-band resource is base band searching resource, base band demodulating
When resource, baseband channel resource etc. are a variety of, the current base-band resource utilization rate of the acquisition can be obtains each base band money respectively
Multiple base-band resource utilization rates in source.
Preset utilization rate threshold value, be mainly used for control Radio Link establishes quantity, avoids limited base-band resource
It cannot be utilized effectively.Specifically, then explanation is current when current base-band resource utilization rate is lower than preset utilization rate threshold value
Remaining base-band resource is relatively more, at this time when receiving the instruction of corresponding wireless link, can directly establish for it
Corresponding Radio Link guarantees that user terminal normally accesses or improve the communication quality of respective wireless link, makes base-band resource
It can be fully used；But when current base-band resource reaches at or above the preset utilization rate threshold value, it can be said that bright
Current base-band resource is remaining few, needs to carry out reasonable distribution control, avoids existing building receiving corresponding Radio Link
When vertical instruction, corresponding Radio Link just is established for it simply by the presence of enough resources, it would be possible to Virtual Radio Link be caused to be built
Vertical quantity is higher, to seriously affect the problem of real Radio Link normally accesses.
S13: when according to the ratio and base-band resource utilization rate judgement in the presence of the Virtual Radio Link for needing to delete,
Corresponding Virtual Radio Link is deleted, discharges the occupied base-band resource of the Virtual Radio Link with new wireless for establishing
Link.
According to the occupied base-band resource of currently-established Virtual Radio Link of acquisition and currently-established real nothing
The ratio of the occupied base-band resource of wired link and current base-band resource utilization rate judge whether there is the virtual nothing for needing to delete
Wired link, if it is determined that in the presence of then deleting corresponding Virtual Radio Link, discharging the occupied base band money of the Virtual Radio Link
Source increases current base-band resource surplus with this, to promote the utilization rate of base-band resource, make for establishing new Radio Link
Base-band resource can be utilized more fully.
In practical application scene, the foundation of Radio Link generally includes building for Virtual Radio Link and real Radio Link
It is vertical, it is described in detail first below for the establishment process of real Radio Link:
Fig. 3 is referred to, Fig. 3 is a kind of method for building up process signal for real Radio Link that the embodiment of the present invention one provides
Figure, comprising:
S31: the wireless link instruction for being used to indicate the real Radio Link of foundation that base station controller issues is received；
The wireless link instruction that base station controller issues is received specifically, can be, and to the wireless link
Instruction carries out dissection process, to judge the indicated Linktype established of wireless link instruction.It is specific to receive demodulation
Treatment process can be carried out using existing any way, herein with no restrictions.
S32: obtaining current base-band resource utilization rate, judges whether the base-band resource utilization rate got reaches default
The first utilization rate threshold value, if so, going to step S33；If not, going to step S38；
Let it be assumed, for the purpose of illustration, that currently reception resource utilization is L, preset first utilization rate threshold value is L1, here
It that is to say and judging L >=L1When, otherwise namely L < L step S33 is gone to,1When, execute step S38.It should be noted that one
In a little examples, can be after receiving wireless link instruction, then carry out the acquisition of current base-band resource utilization rate with
And the determination of range；It is also possible to first obtain current base-band resource utilization rate and determines its range, it is corresponding wireless receiving
After link establishment instruction, further according to the base-band resource utilization rate for previously having obtained and having determined to execute subsequent step, it that is to say
Simultaneously inevitable sequencing is not present in the two.
S33: obtaining the occupied base-band resource of currently-established Virtual Radio Link and currently-established reality is wireless
The ratio of the occupied base-band resource of link judges that the ratio reaches preset first fractional threshold (assuming that the ratio is
λ, preset first fractional threshold are λ1Namely λ >=λ1), and current base-band resource utilization rate is less than preset second utilization rate threshold
When value, step S34 is gone to；If judging, current base-band resource utilization rate is less than preset second utilization rate threshold value, and the ratio
When less than preset first fractional threshold, step S35 is gone to；If judging, current base-band resource utilization rate reaches preset second and makes
When with rate threshold value, step S36 is gone to；
S34: determine at least there is the Virtual Radio Link for needing to delete；Delete the corresponding void for needing to delete
Quasi- Radio Link；
Assuming that preset second utilization rate threshold value is L2, the ratio got is λ, and preset first fractional threshold is
λ1.In the present embodiment, the second utilization rate threshold value L2Greater than the first utilization rate threshold value L1.Be greater than in current base-band resource utilization rate L etc.
In preset first utilization rate threshold value L1, and it is less than preset second utilization rate threshold value L2(it that is to say L1≤ L < L2), and institute
Ratio λ is stated greater than preset first fractional threshold λ1(namely λ >=λ1) when, determine the virtual radio chain that base station currently has built up
At least there is a Virtual Radio Link in road to need to delete.
S35: refuse to instruct for the wireless link and establish corresponding real Radio Link；
Judge current base-band resource utilization rate be less than preset second utilization rate threshold value (that is to say L1≤ L < L2), but institute
Ratio is stated less than preset first fractional threshold (namely λ < λ1) when, namely current base-band resource utilization rate reached one compared with
High level, and the occupied base-band resource of Virtual Radio Link seldom (that is to say that the ratio is less than preset first ratio
It is worth threshold value), therefore refuse to be that corresponding real Radio Link is established in wireless link instruction.
Alternatively, judge the base-band resource utilization rate be not up to preset third utilization rate threshold value (assuming that third use
Rate threshold value is L3, that is to say L2≤ L < L3), and judge the ratio be equal to 0 when, refuse for the wireless link instruct build
Found corresponding Radio Link.
Alternatively, judging that the base-band resource utilization rate reaches preset third utilization rate threshold value and (that is to say L >=L3) when,
Since current base-band resource utilization rate has had reached a Limiting Level, base station current residual base-band resource is few or insufficient
Think that it distributes enough resources, therefore refuses to be that corresponding Radio Link is established in wireless link instruction.
S36: judge that the base-band resource utilization rate is not up to preset third utilization rate threshold value, and judge that the ratio is big
When 0, step S37 is gone to；Otherwise, step S35 is gone to；
In the present embodiment, it is assumed that third utilization rate threshold value is L3, and third utilization rate threshold value L3Greater than the second utilization rate threshold value
L2。
S37: determine that all Virtual Radio Links currently having built up are required to delete；The corresponding needs are deleted to delete
The Virtual Radio Link removed；
Judging whether the base-band resource utilization rate reaches preset third utilization rate threshold value and (that is to say L2≤ L < L3),
And the ratio be greater than 0 (namely λ > 0) when, it is determined that all Virtual Radio Links currently having built up are required to delete.
In the present embodiment, when determining in the presence of the Virtual Radio Link for needing to delete, deletion is described accordingly to need to delete
Virtual Radio Link, to discharge the occupied base-band resource of the Virtual Radio Link, for establishing new Radio Link.
In the present embodiment, after deleting corresponding Virtual Radio Link, base station current residual base can also be recalculated
Band resource, and go to step S32 and execute above-mentioned steps.
S38: distributing corresponding base-band resource is that corresponding real Radio Link is established in wireless link instruction.
When current base-band resource utilization rate is lower than preset first utilization rate threshold value, at this point, base band surplus resources are opposite
It is more, corresponding Radio Link directly is established for wireless link instruction, makes full use of the base band surplus resources, guarantees to use
Family access success rate of terminal.
It is described in detail below for the establishment process of Virtual Radio Link, refers to Fig. 4, Fig. 4 is that the present invention is implemented
A kind of method for building up flow diagram for Virtual Radio Link that example one provides, comprising:
S41: what reception base station controller issued is used to indicate the wireless link instruction for establishing Virtual Radio Link；
S42: obtaining current base-band resource utilization rate, and judges whether the base-band resource utilization rate reaches the preset 4th and make
With rate threshold value, if so, going to step S43；If not, going to step S44；
In the present embodiment, utilization rate threshold value includes the first utilization rate threshold value and the 4th utilization rate threshold value, it is assumed that is L4, respectively
The use when real Radio Link and Virtual Radio Link are established in the wireless link instruction instruction received.It should be understood that
It is that the first utilization rate threshold value and the 4th utilization rate threshold value can be set to identical, different numerical value also can be set into.
S43: obtaining the occupied base-band resource of currently-established Virtual Radio Link and currently-established reality is wireless
The ratio of the occupied base-band resource of link, and judge that the ratio reaches preset second fractional threshold and (is assumed to be λ2), and should
Base-band resource utilization rate is less than preset 5th utilization rate threshold value and (is assumed to be L5) when, go to step S45；Otherwise, step is gone to
S46；
S44: corresponding Virtual Radio Link is established for wireless link instruction；
When current base-band resource is lower than preset 4th utilization rate threshold value, illustrate that current base band surplus resources are sufficient, it can
To meet the foundation of the Virtual Radio Link well, the foundation of real Radio Link will not be affected greatly, therefore directly
Corresponding base-band resource is distributed for the Virtual Radio Link, to establish Virtual Radio Link.Pass through the Virtual Radio Link
It establishes, the corresponding ascending idle port signal of demodulation of corresponding real Radio Link can be assisted, to improve the communication of Radio Link
Quality.
It should be understood that the foundation of Radio Link (Virtual Radio Link and real Radio Link) can use existing
Meaning wireless link mode, herein with no restrictions.
S45: determining at least there is the Virtual Radio Link for needing to delete in currently-established Virtual Radio Link,
And delete the Virtual Radio Link for needing to delete；
Reach preset 4th utilization rate threshold value in current base-band resource utilization rate, and is less than preset 5th utilization rate threshold
Value, and when the ratio is greater than preset second fractional threshold, determine in current Virtual Radio Link at least there is one
Item needs the Virtual Radio Link deleted.In the present embodiment, when determining in the presence of the Virtual Radio Link for needing to delete, it should delete
Except the Virtual Radio Link of required deletion, to discharge the occupied base-band resource of the Virtual Radio Link.
In the present embodiment, after deleting the corresponding required Virtual Radio Link deleted, current base band can also be recalculated
Resources left situation, and step S42 is gone to, repeat above-mentioned steps.
S46: refuse to instruct for the wireless link and establish corresponding Virtual Radio Link；
Judging that the current base-band resource utilization rate reaches preset 4th utilization rate threshold value, and be less than the described 5th to make
With rate threshold value, but when the ratio is less than preset five fractional threshold；Or current base band utilization rate threshold value has reached the 5th
When utilization rate threshold value (wherein the 5th utilization rate threshold value is greater than the 4th utilization rate threshold value), determine that there is no the virtual nothings new for foundation
Wired link and the Virtual Radio Link deleted, therefore the base-band resource for new Virtual Radio Link distribution is less or insufficient,
To which refusal is that corresponding Virtual Radio Link is established in wireless link instruction, guarantee established Virtual Radio Link
Normal operation.
In the present embodiment, deleting corresponding Virtual Radio Link can be according to each Virtual Radio Link currently having built up
Priority, delete the Virtual Radio Link of highest priority in each Virtual Radio Link；Wherein priority can be according to each void
At least one of the quasi- occupied base-band resource grade of Radio Link, link setup time span and signal strength are calculated.
It should be understood that the height of priority be it is opposite, in the standard difference of institute's reference, the height of priority
It is different, therefore the present embodiment is not necessarily limited to delete the Virtual Radio Link of highest priority.For example, in virtual nothing
The occupied base-band resource higher grade of wired link, and link setup time span is longer, and signal strength is poorer, when priority is higher, answers
When the Virtual Radio Link for deleting highest priority；And in the occupied base-band resource higher grade of Virtual Radio Link, link setup
Time span is longer, and signal strength is poorer, when priority is lower, should delete the minimum Virtual Radio Link of priority.
It is possible to further according to the occupied base-band resource grade of each Virtual Radio Link, link setup time span and
Signal strength three calculates the corresponding priority of each Virtual Radio Link currently having built up jointly:
P=aX+bY+cZ, wherein P indicates the numerical priority value of Virtual Radio Link, and X is indicated shared by the Virtual Radio Link
Base-band resource level value, Y indicate that the link setup time span level value of the Virtual Radio Link, Z indicate the virtual nothing
The signal strength scale numerical value of wired link, a, b, c respectively indicate the weighted factor of X, Y, Z.There is corresponding virtual nothing determining
When wired link needs to delete, priority is deleted in each Virtual Radio Link most by priority calculation method that this programme provides
High Virtual Radio Link, higher, the dtr signal that will wherein can occupy base-band resource well, link setup time are longer virtual
Radio Link carries out delete processing, avoids such Virtual Radio Link to the occupancy of base-band resource, is conducive to improve base band money
The utilization rate in source.For example, certain Virtual Radio Link signal having built up is very poor, corresponding real Radio Link is risen at all
It is acted on less than due aid demodulation, but it still occupies certain base-band resource, this causes limited base-band resource
Certain waste is unfavorable for improving the utilization rate of base-band resource.And the priority algorithm that this programme provides can be by this part void
Quasi- Radio Link is released effectively, and the base-band resource obtained after release can also be used to establish new Radio Link, because
This can effectively access more user terminals, especially in communication peak time, can dramatically improve user terminal
It is successfully accessed rate, promotes the usage experience of user.
Certainly, it is not limited to the above example for the calculating of priority, can also carry out COMPREHENSIVE CALCULATING according to other correlative factors,
Or a certain factor therein is selected to be calculated: for example calculating the excellent of each Virtual Radio Link only according to signal strength
First grade, signal strength is weaker, and priority is higher, needs to establish corresponding Radio Link in judgement, exist needs delete it is virtual
When Radio Link, the most weak Virtual Radio Link of the signal strength can be deleted, the Virtual Radio Link is avoided to provide base band
The consumption without reason in source discharges the occupied base-band resource of the Virtual Radio Link, with for establishing corresponding new Radio Link,
Improve the utilization rate of base-band resource.
By combining the occupied base-band resource grade of Virtual Radio Link, link setup time span, signal strength to count jointly
Calculate each Virtual Radio Link
After dischargeing the Virtual Radio Link of highest priority, the utilization rate of current base-band resource can also be recalculated
Situation, and judge whether to meet corresponding condition again, correlation step is repeated, is established until being instructed for the Radio Link
Corresponding Radio Link is refused to establish corresponding Radio Link for it.
In some instances, a priority threshold value can also be set, in the Radio Link having built up accordingly, each nothing
The priority of wired link can directly discharge the Radio Link after reaching the priority threshold value.That is to say to delete simultaneously
Except all Radio Links for meeting priority threshold value, release efficiency is promoted.
In the present embodiment, the establishment process of Virtual Radio Link and real Radio Link uses two sets of corresponding utilization rates
Threshold value and fractional threshold (real Radio Link uses: the first utilization rate threshold value, the second utilization rate threshold value, third utilization rate threshold value with
And first fractional threshold；Virtual Radio Link uses: the 4th utilization rate threshold value, the 5th utilization rate threshold value and the second ratio threshold
Value), it should be noted that two sets of utilization rate threshold values respectively used and the numerical value being specifically arranged between fractional threshold can phases
Together, it can also be different.For example, the numerical value of the first utilization rate threshold value and the 4th utilization rate threshold value can be set to identical, second makes
It can be set to the numerical value of rate threshold value and the 5th utilization rate threshold value identical, this is no longer going to repeat them, in other words described pre-
If utilization rate threshold value and fractional threshold can be according to practical application scene flexible setting, however it is not limited to some specific numerical value.
Baseband resource managing method provided in an embodiment of the present invention, by obtaining current base-band resource utilization rate, judgement should
When base-band resource utilization rate reaches preset utilization rate threshold value, the occupied base band of currently-established Virtual Radio Link is obtained
The ratio of resource and the currently-established occupied base-band resource of real Radio Link, according to the ratio and the base-band resource
When utilization rate judgement is in the presence of the Virtual Radio Link for needing to delete, corresponding Virtual Radio Link is deleted, discharges the virtual nothing
The occupied base-band resource of wired link is for establishing new Radio Link；This programme is according to currently-established virtual radio chain
The ratio and current base band of the occupied base-band resource in road and the currently-established occupied base-band resource of real Radio Link provide
Source utilization rate actively discharges established Virtual Radio Link accordingly, avoids the Virtual Radio Link currently established
The more influence of quantity real wireless link the problem of, the base-band resource of release can be used for new Radio Link in time
It establishes, especially controls established virtual radio by actively discharging corresponding Virtual Radio Link in communication peak time
The quantity of link accesses more UE as far as possible, and reducing user can not occur the case where normal communication, so that improving user makes
With experience.
Embodiment two:
For a better understanding of the present invention, the present embodiment on the basis of example 1, in conjunction with specific example to this hair
The baseband resource managing method that bright embodiment provides is described in detail.
Fig. 5 is referred to, with certain UMTS (Universal Mobile Telecommunications System, general shifting
Dynamic communication system) site configuration co-frequency cell mentions according to embodiments of the present invention for there is the access of a large number of users terminal in peak time
The baseband resource managing method of confession illustrates the specific implementation step of the baseband resource managing method of real Radio Link.
S51: the wireless link instruction that base station controller issues is received, and carries out instruction parsing；
S52: judge that wireless link instruction is used to indicate real wireless link, and current baseband board searching resource makes
With rate less than 75%, then corresponding base-band resource is distributed for establishing the reality Radio Link；
Specifically, for the new real wireless link distribution relevant search resource that the needs are established, if be allocated successfully, configuration
Base band completes the foundation of real Radio Link；If distribution failure, real wireless link failure.It further, can also be
The response results of real wireless link success and/or failure are sent to base station controller.
S53: if judging, the current base band searching resource utilization rate of baseband board is greater than 75% but less than 85%, and λ >=25%
(λ is that the currently-established occupied base-band resource of Virtual Radio Link and currently-established real Radio Link are occupied
The ratio of base-band resource), calculate the priority for the Virtual Radio Link currently having built up and sequence；
Assuming that currently there is three effective Virtual Radio Links, wherein UE0Base band searching resource ratio is occupied to be 2%, build
The chain time be 15ms, search signal it is very weak when, calculate UE0The value of corresponding X, Y, Z are respectively 2,1,4；UE1Base band is occupied to search
When Suo Ziyuan ratio is 2%, the link setup time is 35ms, search signal is weaker, UE is calculated1The value of corresponding X, Y, Z is respectively
