Embodiment
Thinking of the present invention is that bandwidth is adjusted adapting to transmitting power, thereby reduces BLER value, minimizing call drop phenomenon.At first network side is judged the stability of Radio Link according to the quality of up link, and according to judged result, relatively poor at link-quality, when not satisfying stability condition, reduce the bandwidth of Radio Link, thereby can guarantee the communication quality of subscriber equipment; In addition, when communication environment makes moderate progress, after link-quality recovered, the present invention was by recovering the bandwidth after the downward modulation, thereby can make the user keep unimpeded process of communication service continuously.
When network side judges whether Radio Link satisfies stability condition, can adopt dual mode, a kind of is whether to satisfy certain condition by the transmitting power of judging radio up-line, and another kind is whether the up BLER value of judging Radio Link satisfies certain condition.The present invention can also can specifically please refer to the embodiment of back in conjunction with two kinds of conditions as Rule of judgment by judging a kind of condition wherein.
As shown in Figure 1, the schematic flow sheet for the embodiment one of up link method of adjustment of the present invention may further comprise the steps:
Step 101, network side calculates the last transmitting power thresholding of trigger event, launches power threshold down, and should go up the transmitting power thresholding, launch power threshold down and send to subscriber equipment, described threshold value can be provided with according to sub-district situation and current link circuit condition, for instance: channel parameter maximum transmission power P
Max(Maximum allowed TX power) is that channel is set up or channel when reshuffling, and disposes parameter value to Radio Link by UTRAN, and its correspondence the resource that system assignment is given this link.Can utilize this maximum transmit power, dispose some constant offset amounts for the functional module that realizes bandwidth control, can calculate the threshold value up and down of transmitting power like this, it is higher that each channel capacity of this mode or cell environment change the mode efficient that just recomputates threshold value.When channel capacity or cell environment condition change, utilize maximum transmission power to deduct the constant offset amount and just can obtain threshold value up and down.Certainly the present invention also supports to adopt the mode of Dynamic Selection side-play amount, promptly changes the mode that just recomputates threshold value according to each channel capacity or cell environment.
The transmitting power of the transmit power limited of hypothesis triggering here incident is limited to P to the doorstep
A1, the transmitting power Xiamen of triggering transmit power limited releasing incident is limited to P
B1, the threshold-offset up and down of its correspondence is Δ A1 and Δ B1, transmitting power Upper threshold P
A1With transmitting power Lower Threshold P
B1, can try to achieve by following formula:
P
A1＝P
max-ΔA1，
P
B1＝P
max-ΔB1；
Except transmitting power upper threshold and Xiamen limit value are set, also need Event triggered time and exponent filtering coefficient are provided with.
Step 102 is higher than transmitting power Upper threshold P when subscriber equipment detects uplink transmission power
A1The time, subscriber equipment sends the transmit power limited incident by air interface signaling to network side; When detecting uplink transmission power, subscriber equipment is lower than transmitting power Lower Threshold P
B1The time, subscriber equipment sends transmit power limited by air interface signaling to network side and removes incident.What adopt in the present embodiment is the mode of Event triggered, promptly when subscriber equipment detects certain incident, can trigger the reporting events to network side, judge assessment by network side then, this mode signaling amount is few, has both reduced taking of air interface, has reduced the processing time of signaling again.In addition, the mode that can also report in the employing cycle promptly according to reporting uplink transmitting power regularly of certain cycle, is judged assessment by network side then, judges whether Radio Link meets stability condition, and its judgment criterion is identical with the Event triggered mode.
Step 103, when network side receives the transmit power limited incident of user equipment to report, and do not receive transmit power limited releasing incident in the given time, at this moment promptly think not meet stability condition,, perhaps received transmit power limited releasing incident in the given time again if do not receive the transmit power limited incident, think that then Radio Link remains stable, promptly meet stability condition, so end operation, otherwise execution in step 104;
Step 104, network side utilizes the reduction of speed module directly or several times the bandwidth of Radio Link to be lowered to the target bandwidth value by former bandwidth value, the target bandwidth value is at the predefined bandwidth value of network side, when this target bandwidth value is set, guarantee basicly stable speech quality in the time that the target bandwidth value should being lowered in the bandwidth of Radio Link.
Thisly judge link according to the subscriber equipment uplink transmission power whether stable method has characteristics intuitively, in addition, also can directly judge according to the bLock error rate of up link whether link is stable.As shown in Figure 2, carry out the schematic flow sheet of embodiment two of the method for bandwidth downward modulation according to uplink quality for the present invention, may further comprise the steps:
Step 201, submodule in the RRM module of network side-exterior ring power control module (Outer Loop Power Control is called for short OLPC) is according to different bLock error rate measurement period, bLock error rate Upper threshold, bLock error rate Lower Threshold, Event triggered time and/or the exponent filtering coefficients of type of service configuration;
Step 202, OLPC adds up the BLER value of up link in the measurement period of setting, its statistical value adopts exponent filtering, report the excessive message of BLER when BLER value that OLPC counts on surpasses under the situation of BLER Upper threshold in the triggered time, in the triggered time, be lower than under the situation of BLER Lower Threshold and report BLER recovery message to the RRM module when OLPC counts on BLER value;
Step 203, network side judge that whether the BLER value surpasses the BLER Upper threshold, if do not surpass, thinks that then link is stable, then end operation; Otherwise execution in step 204;
Step 204, network side utilize the reduction of speed module directly or several times the bandwidth of wireless communication link to be lowered to the target bandwidth value by former bandwidth value.
More than among two embodiment, adopted two kinds of different judgement of stability conditions respectively: whether transmitting power near transmitting power Upper threshold P
A1, and whether the BLER value surpass the BLER Upper threshold, can also two conditions uses simultaneously, triggers bandwidth again and reduce when satisfying simultaneously.
In last two embodiment, the adjustment of bandwidth has dual mode: descend mediation directly to be lowered to the target bandwidth value several times.Xia Tiao implication is to reduce stage by stage several times, be about to be divided into a plurality of stages between former bandwidth value and the target bandwidth value, after being lowered to a stage at every turn, can do decision operation one time according to uplink transmission power, judge whether to reach the condition of recovering bandwidth, judge whether to allow to recover bandwidth, can also judge whether power limited still according to existing transmitting power situation, if allow to recover bandwidth, then carry out recovery operation, promptly raise the bandwidth of Radio Link; If still power limited then continues to adjust downwards, up to thoroughly being lowered to the target bandwidth.
The following examples are the schematic flow sheet of timing under the mode bandwidth several times, as described in Figure 3, are the schematic flow sheet of the present invention to the bandwidth fragmentation downward modulation of wireless communication link, may further comprise the steps:
Step 301, network side is adjusted the bandwidth of Radio Link downwards by former bandwidth value;
Step 302 judges whether allow to recover bandwidth, is execution in step 303 then, otherwise execution in step 304;
Step 303, network side upwards reverts to former bandwidth value with the bandwidth of Radio Link by bandwidth value in the middle of adjusted, and end operation;
Step 304, network side judge whether power is still limited, are execution in step 305 then, otherwise end operation;
Step 305, network side is adjusted the middle bandwidth value of next stage with the bandwidth of Radio Link downwards by bandwidth value in the middle of adjusted;
Step 306, network side judge whether allow to recover bandwidth, are execution in step 307 then, otherwise execution in step 308;
Step 307, network side upwards recovers the upper level bandwidth value with the bandwidth of Radio Link by bandwidth value in the middle of adjusted, and end operation;
Step 308, network side judge whether power is still limited, are execution in step 309 then, otherwise end operation;
Step 309, network side judge whether bandwidth has been lowered to the target bandwidth value, are end operations then, otherwise execution in step 305 continues the downward modulation bandwidth.
Here for example segmentation downward modulation bandwidth is described, suppose that former bandwidth is 384; Behind power limited, can be lowered to 128; If power is still limited, then adjust to 64 by 128; If power recovers, then return to 384 from 128; After being lowered to 64,, then return to 128 again if power recovers.Wherein 64 be set to be a final downward modulation target bandwidth, can have the target bandwidth of a plurality of intergrades.
With respect to above adjustment bandwidth several times, can also adopt the mode of direct downward modulation, be that network side is adjusted the target bandwidth value with the bandwidth of Radio Link downwards by former bandwidth value, and judge whether that permission recovers bandwidth, be then the bandwidth of wireless communication link upwards to be reverted to former bandwidth value by the target bandwidth value, and end operation.
In the mode of above two kinds of adjustment bandwidth, the operation that judges whether to allow to recover bandwidth is identical, all be to judge whether to recover bandwidth according to the transmitting power thresholding that is provided with, here adopt the mode of Event triggered, promptly the transmitting power that measures when subscriber equipment is lower than transmitting power Lower Threshold P
B2The time, subscriber equipment sends transmitting power by air interface signaling to network side and recovers incident; The transmitting power that measures when described subscriber equipment is higher than transmitting power Upper threshold P
A2The time, described subscriber equipment sends transmit power limited by air interface signaling to network side and keeps incident
Before recovery operation, network side can calculate acquisition transmitting power Upper threshold P according to sub-district situation and current link circuit condition
A2With transmitting power Lower Threshold P
B2, and with transmitting power Upper threshold P
A2With transmitting power Lower Threshold P
B2Send to subscriber equipment setting.Subscriber equipment is provided with according to the configuration-direct that network side sends.
The invention provides a kind of set-up mode, be not limited to this setup.At first the transmitting power of hypothesis triggering transmitting power recovery incident is limited to P to the doorstep
A2, the transmitting power Xiamen that the triggering transmit power limited is kept incident is limited to P
B2The threshold-offset up and down of its correspondence is Δ A2 and Δ B2, target bandwidth after the downward modulation is Band_A, former bandwidth is Band_B, in addition, and after the adjustment bandwidth, it is Δ P that transmitting power also has certain difference, this value can be set by the mode of backstage configuration, so just can obtain Upper threshold offset A2 and Lower Threshold offset B2 by simple formula
ΔB2＝ΔA1+ΔP，
ΔA2＝ΔB2。
