Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In cdma system, due to subscriber equipment (User Equipment; UE) size of transmitting power directly can affect the total capacity of cdma system, and the target that power controls is exactly under the condition ensureing UE communication quality, makes the transmitting power of all UE as far as possible little, to promote the capacity of cdma system as much as possible.
Power in cdma system controls to be divided into uplink power control (i.e. control UE transmitting power) and downlink power control (i.e. control NodeB transmitting power) by direction.In uplink and downlink power controls, can also be divided into open Loop Power control and two stages of close-loop power control, wherein open Loop Power control occurs in UE and NodeB when starting to access, and in open Loop Power control, UE or NodeB sets Initial Trans.After close-loop power control occurs in UE and NodeB access, in close-loop power control, UE and NodeB is mutually according to the feedback information Modulating Power of the other side, namely requires that UE and NodeB participates in power adjustment simultaneously.Such as in up power controls, inner-loop power control is that the power between NodeB and UE controls, and open sea wharf is NodeB and radio network controller (Radio Network Controller; RNC) power between controls.In uplink power control, the transmitting power of NodeB control UE.In descending power controls, inner-loop power control is also the transmitting power that the power between NodeB and UE controls to be specially UE control NodeB.Mainly uplink power control is considered in the embodiment of the present invention.
According to existing technical scheme, during upload control controls, according to the difference of power control command transmitting frequency, inner-loop power control mode is divided into again fast inner loop power to control and inner-loop power control at a slow speed, and this inner-loop power control mode is by RNC fixed configurations in advance, cannot change.If therefore fixed configurations inner-loop power control mode is that fast inner loop power controls, then at additive white Gaussian noise (AdditiveWhite Gaussion Noise; AWGN), under channel, because channel circumstance change is little, fast inner loop power control mode will bring the fluctuation of base station receives power to the adjustment of power, make relatively to adopt inner-loop power control mode at a slow speed that performance can be brought to bear gain.Control if fixed configurations inner-loop power control mode is fast inner loop power, then under UE high-speed mobile scene due to channel circumstance change too fast, make the adjustment of fast inner loop power control mode to power be difficult to catch up with the change of channel circumstance, now relatively adopt inner-loop power control mode at a slow speed that performance also will be brought to bear gain.If fixed configurations inner-loop power control mode is inner-loop power control mode at a slow speed, then under the non-awgn channel that UE translational speed is lower, inner-loop power control mode cannot adjust transmitting power in time according to channel variance situation at a slow speed, thus controls relative to fast inner loop power the negative gain bringing throughput.
Based on the above, can know that existing inner-loop power control mode is for being fixedly installed, and causes the efficiency of inner-loop power control lower.Therefore the embodiment of the present invention provides a kind of processing method of inner-loop power control mode, inner-loop power control mode can be configured according to the translational speed of the channel type between UE and NodeB and UE, thus realize carrying out adaptive adjustment to inner-loop power control mode, effectively to improve the efficiency of inner-loop power control, the transmitting power of UE is made to adjust to optimal value, thus effectively promote cdma system capacity, in detail can with reference to the record of following embodiment.
The flow chart of the processing method of the inner-loop power control that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the executive agent of the processing method of the inner-loop power control of the present embodiment is RNC, and as shown in Figure 1, the processing method of the inner-loop power control of the present embodiment, specifically can comprise the steps:

(2) RNC configures described inner-loop power control mode for inner-loop power control mode at a slow speed;
Because the environmental change of awgn channel is less, can think that being in this channel UE moves at a slow speed.Therefore, when channel type is awgn channel, need not further judge the speed of UE again.
(3) RNC judges whether the translational speed of UE is more than or equal to pre-set velocity threshold value; When the translational speed of UE is more than or equal to pre-set velocity threshold value, perform step (4); Otherwise when the translational speed of UE is less than pre-set velocity threshold value, perform step (5);
Wherein pre-set velocity threshold value can be chosen according to actual scene, and such as can choose pre-set velocity threshold value is 120KM/h.
