Method of the present invention also comprises in concrete implementation procedure: consider preceding reverse right access parameter information or other parameter informations of carrier wave of the existing reference that exists, confirm the reverse channel initial transmitting power of this newly-built reverse carrier wave.Specifically can for: if the reverse carrier wave that has not existed in the same band limits of this newly-built reverse carrier wave; Then also need adopt following mode to carry out the confirming of Initial Trans value of newly-built reverse carrier wave; Promptly consider to exist in other frequency ranges existing before the reverse right access parameter information of carrier wave, confirm the reverse channel initial transmitting power of this newly-built reverse carrier wave according to corresponding access parameter information.The concrete implementation procedure of this method comprises:
As shown in Figure 2; Reverse carrier wave is to being F1/R1 before the hypothetical reference; Access parameter with reference to forward carriers is OpenLoopAdjust_FL1 (open loop power adjustment) and ProbeInitialAdjust_FL1 (access exploration is initially adjusted); The terminal receives that the pilot power estimated value with reference to forward carriers is Pilot_Power_FL1; If with reference to reverse carrier wave Traffic Channel pilot transmit power estimated value is PilotPower_RL1, then calculate the preceding reverse carrier wave of this reference value and power reference Reference_1=PilotPower_RL1+Pilot_Power_FL1-OpenLoopAdjus t_FL1-ProbeInitialAdjust_FL1 corresponding to F1/R1; Perhaps, also can be through transmitting signaling downwards adjustment parameter A djustParameter, i.e. Reference_1=PilotPower_RL1+Pilot_Power_FL1-AdjustParamet er; Wherein, AdjustParameter mainly is a system according to reference to the pilot transmit power (being made as B) of the pilot transmit power (being made as A) of forward carriers, forward carriers that newly-built reverse carrier wave is corresponding, definite with reference to the mean receiving power (being made as D) of the mean receiving power (being made as C) of reverse carrier wave and newly-built reverse carrier wave, for example, and AdjustmentParameter=A-B+C-D; On the basis of calculating this value that obtains; Some other adjustment can also be done by system, for example, and according to QoS (quality of service) demand of business; Dynamically carry out some adjustment, or the like;
Then, before all are existing, calculate last required new business channel pilot frequency Initial Trans InitialPilotPower_RL the reverse value and power reference of carrier wave to correspondence;
Described computational methods specifically comprise following two kinds:
First kind of concrete computational methods is:
Select with nearest at interval existing of newly-built reverse carrier frequency before reverse carrier wave oppositely carrier wave is right before as a reference; Its pairing reference value is calculated the Initial Trans of reverse newly-built carrier wave Traffic Channel pilot tone; As shown in Figure 2, the reverse channel initial transmitting power InitialPilotPower_RL4 of newly-built reverse carrier wave is:

In Fig. 2, if only select reference value average of nearest frequency range, then can get K1=0, K2=K3=1/2 is:
InitialPilotPower_RL4＝(Reference_2+Reference_3)/2-(Pilot_Power_FL4-OpenLoopAdjust_FL4-ProbeInitialAdjust_FL4)。
Among the present invention, there is not existing reverse carrier wave, but when having forward carriers, can also obtains the reverse channel initial transmitting power of newly-built reverse carrier wave through following method when being in the scope of same frequency range with newly-built reverse carrier wave.
Be specially the access parameter OpenLoopAdjust_FL4 and the ProbeInitialAdjust_FL4 that at first confirm current newly-built forward carriers, the terminal receives that the pilot power of forward carriers is Pilot_Power_FL4;
Then, the Initial Trans InitialPilotPower_RL4 that calculates this reverse newly-built carrier wave Traffic Channel pilot tone is:
InitialPilotPower_RL4＝-Pilot_Power_FL4+OpenLoopAdjust_FL4+ProbeInitialAdjust_FL4+TrafficToAccessRatio；
Wherein, TrafficToAccessRatio (business and access power ratio) is a parameter, can specify in advance also and can be issued by network.
In a word, then as shown in Figure 3 when promptly confirming carrier reverse channel initial transmitting power in the method for the present invention when being the Initial Trans of the Traffic Channel pilot tone of newly-built reverse carrier wave, specifically may further comprise the steps:
Step 31: judge whether to exist with this newly-built reverse carrier wave to be in the reverse carrier wave in the same band limits, if exist, then execution in step 32, otherwise, execution in step 33;
