Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
For above-mentioned purpose, the feature and advantage that make the embodiment of the invention can become apparent more, the embodiment of the invention is described in further detail below in conjunction with the drawings and specific embodiments.
The Poewr control method of embodiment of the invention base station, go for adopting adaptive multi-rate (Adaptive Multi-Rate, abbreviation AMR) communication system of speech coding technology, can be 2G, the communication system of 3G or 4G, such as, 2G is with global system for mobile communications (Global System ForMobile Communications, be called for short: GSM) be example, 3G is Wideband Code Division Multiple Access (WCDMA) (WidebandCode Division Multiple Access, be called for short: WCDMA), or Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, be called for short: TD-SCDMA), or code division multiple access CDMA2000 is example, and 4G is that (LongTerm Evolution is called for short: LTE) be example long evolving system.In above-mentioned communication system, adopt the Poewr control method of the embodiment of the invention similar.For convenience of description, the embodiment of the invention is that example is specifically described with the gsm communication system.
Fig. 1 is a kind of basic station transmitting power control method method of one embodiment of the invention schematic flow sheet, and as shown in Figure 1, basic station transmitting power control method may further comprise the steps:
Receive the coding mode request CMR that user equipment (UE) sends, comprise coding mode among this CMR, the request base station sends data with the coding mode among the CMR to UE.
In gsm system, when using the AMR speech coding technology, UE periodically sends CMR to the base station, and the request base station sends signal with the coding mode of asking among the CMR to UE.UE sends a CMR by the every 40ms of the form that steals speech frame to the base station, carries the coding mode of UE to the transmission downstream signal of base station requests in this CMR.That is, the base station receives the CMR of a UE transmission every 40ms.
Be understandable that in gsm communication system, the variation of the quality of eating dishes without rice or wine between UE and the base station can cause the instability of communication quality.When eating dishes without rice or wine mass change, the ratio difference of useful signal in the receptible transmission signals of UE, so the also corresponding difference of coding mode of UE request base station transmit signals.
When the matter of eating dishes without rice or wine is measured, effective information in the signal that transmits between UE and the base station is more, redundant less, corresponding the higher coding mode of useful signal, when eating dishes without rice or wine ropy the time, effective information in the signal that transmits between UE and the base station is few, needs more redundant detecting error code, corresponding the lower coding mode of useful signal.
Therefore, when the quality of eating dishes without rice or wine improved, UE sent CMR to the base station, and the request base station sends downstream signal with the coding mode of higher numbering to UE.Opposite, when eating dishes without rice or wine degradation, UE sends CMR to the base station, and the request base station sends downstream signal with the coding mode of lower numbering to UE.Under the situation that the quality of eating dishes without rice or wine remains unchanged, when the quality of eating dishes without rice or wine was better, UE sent the higher CMR of useful signal ratio to the base station, and when eating dishes without rice or wine when second-rate, UE sends the lower CMR of useful signal ratio to BRS.
UE sends among the CMR of base station and is comprising coding mode, and the base station obtains the coding mode of CMR from received CMR signal.Can will be appreciated that when the quality of eating dishes without rice or wine was better, the useful signal ratio of this coding mode was higher, eat dishes without rice or wine when second-rate that the useful signal ratio of this coding mode is lower.Different coding pattern among the CMR can be numbered or specific symbol or different titles are distinguished mutually.
Description from step 110 can be judged the situation of the current quality of eating dishes without rice or wine as can be known according to coding mode.For example, the coding mode that can require from received CMR can be judged the level of the current quality of eating dishes without rice or wine, and the variation of the coding mode that requires from CMR simultaneously can be judged the variation of the quality of eating dishes without rice or wine.Can comprehensively the eat dishes without rice or wine variation of the level of quality and the quality of eating dishes without rice or wine of base station determines whether to need to adjust the transmitting power of base station, and adjusts at needs under the situation of transmitting power of base station, how to adjust.
When adjusting the transmitting power of base station according to coding mode, make signal quality and the signal level transmitted between UE and the base station satisfy certain requirement, obtain stable communication quality preferably.Therefore, second-rate when what communicate by letter, need the transmitting power of raising base station in time.Fine when the quality of communication, can suitably reduce the transmitting power of base station.Be understandable that the transmitting power of adjusting the base station herein is meant adjusts the channel transmitting power of base station at this UE place.Usually, in line with the principle that fast liter falls slowly, can make signal maintain level preferably to the adjustment of the transmitting power of base station.
Present embodiment receives the CMR that UE periodically sends, and obtains the coding mode of asking among the CMR, and adjusts the transmitting power of base station according to the variation of the value of this numbering and number value.Because the emission cycle of CMR is 40ms, therefore, once judgement can be done every 40ms in the base station, can in time adjust the transmitting power of self according to the quality situation of eating dishes without rice or wine, reach the purpose of fast power control, make the power control variation of adaptation network environment in time of base station.
Fig. 2 is the another kind of basic station transmitting power control method method of an one embodiment of the invention schematic flow sheet, and as shown in Figure 2, a kind of basic station transmitting power control method of another embodiment of the present invention may further comprise the steps:
Step 210 receives the coding mode request CMR that user equipment (UE) sends;
Wherein, concrete receive mode can be referring to the step 110 of a last embodiment.
Step 220 is obtained the coding mode among the CMR;
Wherein, concrete receive mode can be referring to the step 120 of a last embodiment.
In step, when the coding mode among the CMR is distinguished different coding modes with coding, the ratio difference of the useful signal of the coding mode transmission of different numberings.Suppose, comprise 4 coding modes that are numbered 1-4 in the CMR set, MODE1, MODE2, MODE3, MODE4, the ratio of useful signal of numbering ascending coding mode is more and more higher.The coding mode that sends when the CMR request base station that UE sends to the base station is MODE1, mean then obtain this coding mode be numbered 1, for other coding mode, by that analogy.Be understandable that, owing to UE periodically sends CMR to the base station, so the corresponding CMR that periodically receives the UE transmission in base station, the base station obtains the numbering of coding mode in the continuous CMR request that is received continuously.
Because the coding modes of different numberings mean the different quality of eating dishes without rice or wine, the transmitting power that is understandable that adjustment is to obtain stable preferably communication quality in order to make, both needed UE and between the signal quality and the signal level of transmission satisfy certain requirement.Second-rate when what communicate by letter, need the transmitting power that in time improves.When communication quality fine, the transmitting power that can suitably reduce.
The numbering of the coding mode that the base station requires from received CMR can be judged the level of the current quality of eating dishes without rice or wine, the variation of the coding mode that from CMR, requires simultaneously numbering, and the variation of the quality of eating dishes without rice or wine can be judged in the base station.Can comprehensively the eat dishes without rice or wine variation of the level of quality and the quality of eating dishes without rice or wine of base station determines whether to need to adjust the transmitting power of base station, and adjusts at needs under the situation of transmitting power of base station, how to adjust.
Step 230 judges whether the numbering of coding mode remains unchanged;
In this step, need adjust the transmitting power of base station, remain unchanged if the result who judges is the numbering of coding mode according to the numbering of coding mode, execution in step 240, if the result who judges is the numbering of coding mode, execution in step 250.Whether in step 240 and 250, changing according to coding mode numbering is divided into two kinds of situations and uses.
Step 240 when the numbering of continuous a plurality of coding modes remains unchanged, is adjusted the transmitting power of base station according to the numbering of coding mode;
When the variation of continuous a plurality of coding modes remains unchanged, illustrate that the quality of eating dishes without rice or wine is basicly stable, can judge that the quality of eating dishes without rice or wine this moment keeps being stabilized in relatively poor state and still is stabilized in state preferably by the value of this coding mode, can determine whether to need to adjust the transmitting power of base station thus.
Step 250 when the numbering of coding mode changes, is adjusted the transmitting power of base station according to the variation of coding mode numbering;
As from the foregoing, the variation of coding mode numbering means the variation of the quality of eating dishes without rice or wine, therefore can determine the variation of the quality of eating dishes without rice or wine according to the variation of the numbering of coding mode, when the quality of eating dishes without rice or wine changed, the transmitting power of adjusting the base station made signal satisfy certain quality.
Be understandable that continuous a plurality of concrete number in this step can be predefined.When the coding mode that is used for judging is two, then carrying out base station transmitting power adjustment judgement needs a cycle that sends CMR, when the coding mode that is used for judging is three, then carries out the cycles that a base station transmitting power adjustment is adjudicated needs two to send CMR, other situations, by that analogy.
In the present embodiment, when the numbering of continuous a plurality of coding modes remains unchanged, can or make up the transmitting power of adjusting the base station according to one of following method in the step 240:
Under the situation of coding mode numbering, improve the transmitting power of base station less than the first default thresholding; The numbering and the first default thresholding of coding mode are compared, suppose in MODE1, MODE2, MODE3, MODE4, when being MODE1 and MODE2, the coding mode of CMR request means and eats dishes without rice or wine second-rately that need to adjust, the first default thresholding that then can set numbering is 2.Situation about remaining unchanged when coding mode is if the numbering of coding mode smaller or equal to 2, then needs to improve the transmitting power of base station.Be understandable that this first default thresholding can be set as required.
Under the situation of coding mode numbering, reduce the transmitting power of base station greater than the second default thresholding.Suppose that the second default thresholding is 4, then mean that the quality of eating dishes without rice or wine is fine during for MODE4 when coding mode, then can reduce the transmitting power of base station slowly.Equally, this second default thresholding can be set as required.
In addition, in the present embodiment, when the numbering of coding mode changed, step 250 can or make up the transmitting power of adjusting the base station according to one of following method:
When the coding mode numbering is reduced to the first default thresholding, improve the transmitting power of base station.When the coding mode numbering reduces, can judge the quality of eating dishes without rice or wine and reduce, in this case, there are two kinds of possibilities, first kind of situation is that although the quality of eating dishes without rice or wine reduces, can also satisfy signal has preferable quality.Corresponding is: though the coding mode numbering reduces, be not reduced to the first default thresholding, therefore do not need this increase base station transmitting power.Second kind of situation is, the quality of eating dishes without rice or wine reduces, and the numbering of coding mode is reduced to the first default thresholding among the CMR that UE asked after reducing, and illustrates that the quality of eating dishes without rice or wine is reduced to be not enough to provide signal quality preferably to UE, therefore, need to improve the transmitting power of base station.For example, presetting thresholding when first of coding is 2, if coding mode becomes MODE3 from MODE4, then do not need to improve base station transmitting power, if and coding mode becomes MODE1 from MODE3, perhaps become MODE1, then do not need to improve base station transmitting power, then need in time to improve base station transmitting power from MODE2.
When the coding mode numbering increases to the second default thresholding, reduce the transmitting power of base station.When the coding mode numbering increases, can judge the quality of eating dishes without rice or wine and improve, in this case, there are two kinds of possibilities, first kind of situation is although the quality of eating dishes without rice or wine improves, can't provide signal quality preferably.Corresponding is: though the coding mode numbering increases, do not increase to the second default thresholding, therefore can not reduce base station transmitting power.Second kind of situation be, the quality of eating dishes without rice or wine improves, and the numbering of coding mode increases to the second default thresholding among the CMR that UE asked after improving, and illustrate that the quality of eating dishes without rice or wine brings up to very high quality, therefore, needs the transmitting power of raising base station.In order to guarantee communication quality preferably, the second default thresholding can be bigger than the first default thresholding.For example, when the first default thresholding of numbering was 2, the second default thresholding that can establish numbering was 4.
In addition, in the present embodiment, except can independently adjust the transmitting power of base station as base station among the above-mentioned embodiment according to coding mode, can also be in conjunction with the transmitting power of adjusting the base station in the prior art according to the instruction of base station controller, wherein, report forms according to the UE periodic measurement in the instruction of base station controller.Common with coding mode and measurement report as the factor of adjusting base-station transmitting-power.
In the present embodiment, adopt coding mode and measurement report to adjust jointly under the situation of base-station transmitting-power, can limit the stride scope that adopts coding mode to adjust base station transmitting power, make the stride of adjusting the transmitting power of base station according to coding mode, adjust the stride of the transmitting power of base station less than the base station according to the instruction of base station controller.For example, can the set basis coding mode adjust the stride scope of the transmitting power of base station, between 2db-10db.Like this, can be with the adjusting according to the UE measurement report on the basis of base station transmitting power of prior art, with coding mode as fine setting, more by a small margin carry out the base-station transmitting-power adjustment, make the transmit power variation of base station steady.
Be understandable that according to the different system that present embodiment is used, the base station can be BTS, NodeB and e-NodeB, base station controller can be BSC, radio network controller (RadioNetwork Controller is called for short RNC) and e-NodeB.
In the present embodiment, adopt the coding mode numbering to judge the quality of the quality of eating dishes without rice or wine, and situation of change, thereby the transmitting power of adjustment base station.Because therefore the numbering of coding mode can adjust the transmitting power of base station according to the content of clearly determining in the existing protocol by stipulating in the agreement.In the present embodiment, power is adjusted stride be set in small range, can make the power adjustment more stable.To adjust the transmitting power of adjusting the base station in power and the prior art by coding mode and combine, can be not only in time but also stable carry out the base station transmitting power adjustment.
