Description
Technical field
The present invention relates to moving communicating field, be specifically related to the method for a kind of control user terminal (UE) transmitting power.
Background technology
In the communication process of UE and network side, for the radio network controller (RNC) of UE service will be controlled the transmitting power of UE by the base station that UE inserted.For convenience, the RNC for the UE service with follow-up appearance abbreviates RNC as; Abbreviate the base station that UE inserted of follow-up appearance as base station.Described power control process as shown in Figure 1, concrete power control process may further comprise the steps:
Step 101:RNC also receives the Data Receiving indication from the base station at any time in the UE communication data that receives from the base station; This Data Receiving indication is contained in the base station usually and sends in the described UE communication data of RNC, so that knowing the UE communication data, RNC whether correctly received by the base station, such as: if the base station sends to the value of the Data Receiving indication that comprises among the packet A of RNC is 1, and RNC specified data bag A is correctly received by the base station; If it is 0 that the base station sends to the value of the Data Receiving indication that comprises among the packet A of RNC, RNC determines that then mistake has taken place when receiving packet A in the base station.
Have again,, the monitoring periods with certain time length is set in RNC in advance usually in order to determine that RNC carries out the zero-time of described power control process; When this monitoring periods expired, RNC began to carry out the power control process at UE.
Step 102:RNC calculates the ratio of correct reception data volume and receivable data volume according to the Data Receiving indication of being received in the whole monitoring periods at UE.
Concrete operations are: RNC is according to the indication of the Data Receiving received, the UE amount of communication data that correctly receives from the quilt of base station in the whole monitoring periods is added up, and with accumulated result as correct reception data volume.
Have, RNC also adds up the UE amount of communication data that should receive in the whole monitoring periods again, and with accumulated result as receivable data volume.Particularly, RNC can use the receivable data volume in the whole monitoring periods of prior art accumulative total, concrete accumulative total process is generally: RNC reads the timestamp that is comprised in the UE communication data from the base station, and judge that the pairing time point of timestamp read is whether in the time range of described monitoring periods, if RNC determines that this UE communication data is the receivable data in the monitoring periods; Otherwise RNC determines that then this UE communication data is not the receivable data in the monitoring periods.And the RNC described receivable data that add up are defined as accumulation result the receivable UE amount of communication data that arrives in the whole monitoring periods again.
Obtain after the correct reception data volume and receivable data volume in the whole monitoring periods, RNC with described correct reception data volume divided by described receivable data volume, correctly received the ratio between data volume and the receivable data volume, this ratio can be described as actual Block Error Rate usually.
Step 103:RNC calculates signal interference ratio (SIR) desired value that makes new advances according to the actual Block Error Rate that obtains.Concrete computational methods are: RNC deducts the expectation Block Error Rate that sets in advance with described actual Block Error Rate, with the gained difference divided by the expectation Block Error Rate after, the merchant that will obtain be multiply by the outer shroud step-length that sets in advance again, and will take advantage of the result as the SIR variable quantity.Afterwards, RNC as the new sir target value at UE, further upgrades described current sir target value with this new sir target value with addition result with SIR variable quantity and the current sir target value addition of not upgrading at UE.
The new sir target value that step 104:RNC will calculate sends to the base station, and adjusts transmitting power by the base station according to this sir target value control UE.Certainly, the current sir target value at UE of self preserving also will be upgraded with the new sir target value of receiving in the base station.
Described control method specifically comprises: the base station applies prior art is determined the up SIR of UE, and the up SIR of UE that determines is compared with the sir target value at UE from RNC, if described up SIR is relatively large, the base station reduces order to the UE transmitted power; If described up SIR is less relatively, the base station promotes order to the UE transmitted power; If described up SIR equates with described sir target value from RNC, the base station is then to the maintain an equal level order or UE is not carried out follow-up power control operation of UE transmitted power.
If receive from the power of base station and reduce order, UE encircles step-length in self transmitting power is reduced by one; If receive power ascension order, encircle step-length in one of the transmitting power promotion of UE with self from the base station; If receive that UE then remains unchanged the transmitting power of self from the fair order of the power of base station.The ring step-length is the performance number that sets in advance in described.
So far, the control procedure of UE transmitting power has just been finished.
Along with development of Communication Technique, retransmission technique is introduced in the communication process of UE and network side.Based on retransmission technique, UE can fail the base station the correct data that receive again to the base station transmission, till the base station correctly receives these data.This makes the base station no longer to the Data Receiving indication of RNC transmission at the UE communication data, and only will send to RNC to UE communication data and the pairing transmission number of times of this UE communication data that RNC successfully sends.Described transmission number of times is contained in the base station usually and sends in the described UE communication data of RNC.
In this case, the control procedure that RNC carries out the UE transmitting power as shown in Figure 2, and flow process shown in Figure 2 and flow process shown in Figure 1 have certain difference.
Flow process shown in Figure 2 may further comprise the steps:
Step 201:RNC receives the UE communication data from the base station at any time, and the monitoring periods that sets in advance at the expiration.
Step 202:RNC calculates in the whole monitoring periods ratio at the data volume and the receivable data volume of UE actual reception.Concrete operations are: RNC adds up the UE amount of communication data from the base station in the whole monitoring periods, and with accumulated result as the actual reception data volume.Have, RNC also uses prior art the UE amount of communication data that should receive in the whole monitoring periods is added up again, and with accumulated result as receivable data volume.
Obtain after the actual reception data volume and receivable data volume in the whole monitoring periods, RNC with described actual reception data volume divided by described receivable data volume, obtain the ratio between actual reception data volume and the receivable data volume, this ratio can be described as actual Block Error Rate usually.
Step 203:RNC calculates the sir target value that makes new advances according to the actual Block Error Rate that obtains.Concrete computational methods are identical with corresponding computational methods in the step 103.
The new sir target value that step 204:RNC will calculate sends to the base station, and adjusts transmitting power by the base station according to this sir target value control UE.Concrete control method is identical with corresponding control method in the step 104.
Certainly, the current sir target value at UE of self preserving also will be upgraded with the new sir target value of receiving in the base station.
So far, the control procedure of UE transmitting power has just been finished.
By Fig. 1, Fig. 2 as seen, RNC uses the new sir target value that calculates and by the base station UE transmitting power is controlled, but the process that calculates this new sir target value does not relate to the number of retransmissions of UE communication data, this will cause using described new sir target value the UE transmitting power will be controlled resulting UE transmitting power, be not UE when communication the reasonable transmitting power that should adopt, even and reasonable transmitting power between have big gap, such as: it is too bigger than normal that the UE transmitting power is controlled resulting UE transmitting power, make desired reasonable Block Error Rate scope when too small and this Block Error Rate of Block Error Rate when the base station receives the UE communication data has obviously surpassed proper communication, the part transmitting power that causes UE is by meaningless waste; It is too less than normal perhaps the UE transmitting power to be controlled resulting UE transmitting power, make and desired reasonable Block Error Rate scope when excessive and this Block Error Rate of Block Error Rate when the base station receives the UE communication data has obviously surpassed proper communication cause too much UE communication data correctly to be received by the base station.
Obviously, at present the UE transmitting power is controlled resulting UE transmitting power, be not UE when communication the reasonable transmitting power that should adopt, the part transmitting power that probably causes UE is by meaningless waste, cause power consumption increase, the stand-by time of UE to shorten, be unfavorable for the normal use of UE; Perhaps cause too much UE communication data correctly to be received, cause the proper communication of UE to be affected by the base station.And above-mentioned situation all can reduce user satisfaction.
Summary of the invention

Embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
The method of control UE transmitting power provided by the invention sets in advance monitoring periods, is received from the UE communication data of base station and the number of retransmissions of definite UE communication data by RNC; When monitoring periods expired, RNC was according to the number of retransmissions of received data and the re-transmission threshold value that sets in advance, the re-transmission that obtains UE communication data in the whole monitoring periods number of times that transfinites; And RNC determines in the whole monitoring periods the receivable UE amount of communication data that arrives, according to receivable to the transfinite ratiometer of number of times of UE amount of communication data and described re-transmission calculate new sir target value, again according to this sir target value control UE adjustment transmitting power.
Referring to Fig. 3, Fig. 3 controls the flow chart of UE transmitting power method for the present invention, and this flow process may further comprise the steps:
Step 301:RNC receives from the data of base station at any time and uses the number of retransmissions that prior art is determined received data.Described definite method is generally: RNC also receives the number of retransmissions of this UE communication data in the UE communication data that receives from the base station.The number of retransmissions of described UE communication data is arranged at the base station with the number of retransmissions label manner usually and successfully sends in the described UE communication data of RNC, so that RNC can know that UE retransmits the number of times of this UE communication data to the base station by reading this number of retransmissions sign, such as: if the base station sends to the value of the number of retransmissions sign that comprises among the packet B of RNC is 4, then after reading this number of retransmissions sign, specified data bag B is just correctly received by the base station after having been transmitted 4 times again by UE RNC.
Have again, carry out the zero-time and the termination time of described power control process, need in RNC, to be provided with in advance monitoring periods with certain time length in order to determine RNC; When this monitoring periods expired, RNC began to carry out the power control process at UE.
Step 302:RNC obtains the number of times that data re-transmission transfinites in the whole monitoring periods according to the number of retransmissions of received data and the re-transmission threshold value that sets in advance.Concrete operations are: RNC reads the number of retransmissions that all UE communication datas of receiving in the whole monitoring periods are comprised, and respectively the number of retransmissions that reads is compared with the re-transmission threshold value that sets in advance, if the number of retransmissions that reads is greater than the re-transmission threshold value that is provided with, RNC determine this number of retransmissions institute at the UE communication data transfinite for re-transmission once; Otherwise, RNC determine this number of retransmissions at the UE communication data retransmit as yet and transfinite.
Determined all UE communication datas of receiving in the whole monitoring periods whether retransmit transfinite after, RNC is to adding up for retransmitting the determined re-transmission of UE communication data the transfinite number of times that transfinites, and with accumulation result as the number of times that transfinites of the re-transmission in the whole monitoring periods.
Step 303:RNC calculates the sir target value that makes new advances according to the transfinite ratio of receivable data volume in number of times and the whole monitoring periods of the described re-transmission that obtains.Concrete operations are: RNC uses prior art the UE amount of communication data that should receive in the whole monitoring periods is added up, with accumulated result as receivable data volume.
And, the re-transmission that RNC will obtain is transfinited number of times divided by the receivable data volume that obtains, to remove the result retransmit the probability that transfinites as reality, deduct the expectation that sets in advance and retransmit the probability that transfinites with the actual re-transmission that the obtains probability that transfinites, the gained difference is retransmitted after the probability that transfinites divided by expectation, the merchant that will obtain be multiply by the outer shroud step-length that sets in advance again, and will take advantage of the result as the SIR variable quantity.After obtaining the SIR variable quantity, if ask for the sir target value that is used to control the UE transmitting power according to this variable quantity, then this sir target value is to obtain according to the re-transmission that the relates to UE communication data number of retransmissions probability that transfinites; As seen, this sir target value to the control trend of UE transmitting power is: make the transmitting power of UE more reasonable, the number of times that as far as possible makes UE retransmit same communicated data based on its transmitting power communication the time is lower than the re-transmission threshold value of setting, have rational Block Error Rate during with assurance UE communication, and communication process is more smooth.
Have again, the benefit that the number of times that UE retransmits same communicated data is lower than described re-transmission threshold value also is: in the intensive different communication scenes such as shopping centre of the suburb of spaciousness or building, can guarantee the ceiling value of number of retransmissions of UE proper communication may be corresponding also can be different, and then different re-transmission threshold values need be set; As seen, more help the UE proper communication at the different threshold values that retransmit of different communication scene setting.
Certainly, can be not yet with take advantage of described result as the SIR variable quantity, but as the median of asking for the SIR variable quantity.In this case, RNC adds up the number of retransmissions that all UE communication datas of receiving in the whole monitoring periods are comprised, and with accumulation result divided by described receivable data volume, to remove the result as the actual average number of retransmissions, deduct the expectation average repeat time that sets in advance with the actual average number of retransmissions that obtains again, with the gained difference divided by the expectation average repeat time after, the merchant that will obtain be multiply by described median again, and will take advantage of the result as the SIR variable quantity.
After continuing to calculate according to described median and finally obtaining the SIR variable quantity, if ask for the sir target value that is used to control the UE transmitting power according to this variable quantity, then this sir target value is to obtain according to transfinite probability and average repeat time of the re-transmission that relates to UE communication data number of retransmissions; As seen, this sir target value to the control trend of UE transmitting power is: make the transmitting power of UE more reasonable, the number of times that as far as possible makes UE retransmit same communicated data based on its transmitting power communication the time is lower than the re-transmission threshold value of setting, and the number of retransmissions that makes the UE communication data levels off to the expectation average repeat time that is provided with, have more reasonably Block Error Rate during with assurance UE communication, and communication process is more smooth.
Be lower than the benefit of described re-transmission threshold value except aforesaid UE retransmits the same communicated data number of times, the number of retransmissions of UE communication data level off to described expectation average repeat time benefit also clearly:
In the intensive different communication scenes such as shopping centre of the suburb of spaciousness or building, make UE have the number of retransmissions of optimal communication state may be corresponding also can be different, and then different expectation average repeat times need be set; As seen, can guarantee that at the different expectation average repeat time of different communication scene setting the communications status of UE levels off to the best.
After the application said method obtains described SIR variable quantity, RNC is with the SIR variable quantity and the current sir target value addition of not upgrading at UE that obtain, addition result as the new sir target value at UE, is further upgraded described current sir target value with this new sir target value.
The new sir target value that step 304:RNC will calculate sends to the base station, and adjusts transmitting power by the base station according to this sir target value control UE.Concrete control method is identical with corresponding control method in the step 104.
Certainly, the current sir target value at UE of self preserving also will be upgraded with the new sir target value of receiving in the base station.
So far, the control procedure of UE transmitting power has just been finished.
By the above as can be seen, the method for control UE transmitting power provided by the present invention guarantees the UE transmitting power is controlled resulting UE transmitting power, more helps normal use and the proper communication of UE, improves user satisfaction.
