General; Said n in above-mentioned three kinds of combinations is a weight coefficient, and said AT can confirm this coefficient according to actual conditions, for example; If said AT receives that last time the moment of the response message that includes first reference information of access attempts is more of a specified duration apart from current time; Then said AT can be provided with said n smaller, and for example, said AT can be set to 1 by said n.Said X in above-mentioned three kinds of combinations
0Be the Initial Trans of the current access probe sequence at said this probe place, it can obtain according to computational methods of the prior art, for example, and X
0=-Mean Rx Power+OpenLoopAdjust+OLAOffset+ProbeIntialAdjust, wherein, X
0Be the Initial Trans of access probe sequence, Mean Rx Power is a mean receiving power, by the mean receiving power of AT wireless device measurement during the probe emission; OpenLoopAdjust is the nominal power of open-loop power estimated value, the broadcasted values that in the HRPD system, is issued by AN; OLAOffset is the skew of open-loop power estimated value; AT upgraded this value before each probe sequence of emission; This value pilot frequency intensity that to be AT send the sector of access exploration according to AN broadcast parameter, last transmitting power and AT on reverse traffic channel or access channel obtains; ProbeIntialAdjus t is that access exploration is initially adjusted parameter, the broadcasted values that in the HRPD system, is issued by AN.
In addition; Need to prove; The moment of the response message that includes first reference information of access attempts surpasses certain time interval apart from current time when said AT receives last time; Then said AT can think that said first reference information has not had reference value, and confirms the transmitting power of probe according to prior art.
Step 503, said AT is according to this probe of transmitting power emission of said definite this probe;
Step 504, said AN receives this probe that said AT sends;
Because the transmitting power through compare the probe that obtains according to prior art according to the transmitting power of adjusted said this probe of said first reference information is more accurate; Make and more successfully receive the required signal parameter of probe at the signal parameter that arrives the AN place near said AN at this probe of launching according to the transmitting power of said this probe; So it is bigger that said AN can successfully receive the probability of this probe that said AT sends, can reduce the access delay of AT.And, on certain degree, reduced the interference of said AT to other AT of same sub-district because the signal parameter at this probe arrival AN place more successfully receives the required signal parameter of probe near said AN.
Step 505; Said AN sends the response message that includes second reference information and gives said AT; Said second reference information comprises that the signal parameter of the probe that this succeeds in sending up and Access Network AN successfully receive the required signal parameter of probe, and said signal parameter is signal strength signal intensity or signal to noise ratio; Perhaps, said second reference information comprises the transmit power offset amount; Perhaps, the quantized value of the said second reference information bag transmit power offset amount;
The signal parameter of the said probe that this succeeds in sending up is that said AN is when successfully receiving the probe of this access attempts; Obtain said signal parameter by said AN at its receiver place; Said signal parameter is signal strength signal intensity or signal to noise ratio, also can be other signal index;
It is for the probe that said AN can successfully be received and the said AT of demodulation launches that said AN successfully receives the needed signal parameter of probe; The said signal parameter that said probe need reach in the receiver place of said AN; Said signal parameter can be obtained by the interference of the sensitivity of network receiver, current environment and noise situations etc., belongs to prior art.
Said transmit power offset amount is calculated by said AN, and signal parameter that said transmit power offset amount is the said probe that this succeeds in sending up and said AN successfully receive the difference of the needed signal parameter of probe; Perhaps, said transmit power offset amount is the said difference that successfully receives the signal parameter of needed signal parameter of probe and said this probe that receives.
A kind of method that obtains the quantized value of said transmit power offset amount is exemplified as C=[B/P], and wherein, said C (in embodiments of the present invention, being in particular C1 or C2) is the quantized value of said transmit power offset amount; Said B (in embodiments of the present invention, being in particular B1 or B2) is said transmit power offset amount; Said P is a quantization step, and said quantization step is that said AN and said AT consult perhaps to be chosen by said AN and pass through broadcast or the special said AT of message informing jointly; Said [] is for rounding symbol.The quantized value of said transmit power offset amount also can be calculated according to said transmit power offset amount by additive method.
Need to prove; Said AT can be through the regulation bound said B (in embodiments of the present invention; Be in particular B1 or B2) value be limited in certain scope; If Practical Calculation go out the value (following the B of using ' expression) of B more than or equal to the set upper limit value, then the value of B is taken as and equals said higher limit; If the B ' that Practical Calculation goes out is less than or equal to the lower limit of regulation, then the value of B is taken as and equals said lower limit; If between set upper limit value and lower limit, then being taken as the value of B, the B ' that calculates equals said B '.
Said AT can be through the regulation bound C (in embodiments of the present invention; Be in particular C1 or C2) value be limited in certain scope; If the value of the C that Practical Calculation goes out (following the C of using ' expression) is more than or equal to set upper limit, then the value of C is taken as and equals said higher limit; If the said C ' that Practical Calculation goes out is less than or equal to the lower limit of regulation, then the value of C is taken as and equals said lower limit; If the C ' that calculates is between set upper limit value and lower limit, then the value with C is taken as C '.
Step 506, said AT receives the response message that includes second reference information that said AN sends, and preserves second reference information in the said response message.
Said AT is behind this probe of emission; With waiting for that receiving said AN receives the response message that sends behind this probe, for example, said response message is ACAck; If also do not receive response message through said AT after the regular hour; Then said AT increases the transmitting power of probe and launches probe next time after waiting for the duration, the response message up to said AT receives said AN perhaps reaches till the maximum probe emission quantity Np.
The response of also not receiving said AN when if the access probe quantity of emission reaches said Np, the emission of the next access probe sequence of beginning after then said AT will wait for one period duration promptly begins to confirm the transmitting power of probe again from step 501.If also do not receive the response message of said AN when the quantity of the access probe sequence of emission reaches Ns, then this access attempts finishes with failure.Wherein said Np is the broadcasted values that in the HRPD system, is issued by said AN, and said Ns is consulted to obtain by said AN and said AT, and default value is 3.
Because the parameters such as broadcasted values that AT only issues according to self reception RST and AN in the prior art are estimated the transmitting power of probe; Can accurately not confirm the transmitting power of probe; If the transmitting power of probe is too small, thereby can strengthen the access delay of AT; If the transmitting power of probe is excessive, then can increase interference with other AT of sub-district.Compared with prior art; The scheme that provides in the embodiment of the invention can succeed in sending up the transmitting power that the reference information of storing the back by the AN feedback is confirmed probe according to a preceding probe; Thereby can confirm the transmitting power of probe more accurately, the access delay that reduces AT perhaps reduces the interference with other AT of sub-district.
