With the be treated to example of GSM (Global System for Mobile Communications, global system for mobile communications) base station, the method for processing capacity parameter of the present invention is carried out detailed explanation below to the power amplifier parameter.
In field of wireless communication; What the GSM base station transmitter all generally adopted is close-loop power controlling method; Its principle is: obtain base station feed-forward power through power-sensing circuit, feedback power value of obtaining and expectation performance number are compared, result relatively is used for upgrading the calibration value of power control; Regulate the output of forward power with calibration value, make it be stabilized in the level of expectation power.
Wherein, The expectation performance number (being the power amplifier parameter) of closed power control is to leave in the electricallyerasable ROM (EEROM) (EEPROM) of power amplifier (abbreviation power amplifier) module; The expectation performance number obtains when power amplifier module is produced, altogether 22 power grades.Rate of static power is 0 ~ 6 grade, 0 ~ 15 grade of dynamic power grade, and therefore combination obtains gross power grade totally 22 grades.There is certain difference in power amplifier parameter under the different frequencies under these power grades; On the engineering with its segmentation (being not less than two sections); The interior power parameter of frequency range thinks identical; Obtain the expectation performance number under 22 power grades presetting frequency range earlier, obtain the expectation performance number of other certain preset power grade of frequency range again, should expect the difference power value down by preset power grade thereby obtain each frequency range.The prerequisite of doing like this is to think on the engineering that the expectation power between two frequency ranges has a difference, and this difference can obtain through the expectation power of certain power grade, and the difference of the power grade of other of successive bands is identical with this difference of obtaining.For example set a middle frequency of this frequency range earlier, power grade is set at 2.Obtain the expectation power of this frequency power grade 2 earlier, obtain in other frequency ranges according to this in the middle of the expectation power of power grade 2 of frequency, just obtained the difference between two frequency ranges, the expectation performance number of other each power grades of frequency range of can deriving according to this.For example: the frequency of GSM1800M is divided into 5 sections, can obtains the expectation power difference of the power amplifier parameter value and the different frequency range of 5 frequency ranges.Power amplifier parameter and difference unified through the instrument programming in the EEPROM.After the base station works on power, read the power amplifier parameter in the EEPROM by software through Digital Signal Processing (DSP) chip, the power of being correlated with control makes its base station transmitter be operated in the predetermined electric power scope.
Can know from above-mentioned closed power control principle, leave the correctness of the power amplifier parameter in the power amplifier EEPROM in, control can successful implementation have been played conclusive effect to base station power.If the power contorl parameters of depositing has broken down, the parameter error that perhaps reads out, the power output that directly causes transmitter is unusual, and then will burn out power discharging device, cover to shrink even network moves back clothes, deterioration network index etc.Analyze to find that the reason that causes the power amplifier parameter error has various, for example: programming partial data mistake in the power amplifier parameter programming process; The data wire that reads parameter causes the partial data mistake unusually; Power amplifier unit, power module are unusual etc. all possibly cause the power amplifier parameter error.Various during the type of mistake is also many, the data that some maybe be all are mistake all, but most of just partial data mistake, and above-mentioned to cause the reason major part of power amplifier parameter error be uncontrollable.If parameter error, directly use possibly make the base station normally move, and possibly burn out power amplifier; If only all parameters are carried out a verification, the just directly all compensation of back that makes a mistake so, that kind with loss bigger.
Present embodiment is according to the characteristics of power amplifier parameter, and the power amplifier parameter is carried out the segmentation verification, and (for example: the Cyclic Redundancy Check method), check word all is stored among the EEPROM together with the power amplifier parameter; Do detection when reading the power amplifier parameter when working,, and can detect power amplifier parameter error type, then it is compensated, make the base station can operate as normal in case find parameter error in the base station.
Fig. 3 is the flow chart of method of the processing power amplifier parameter of present embodiment, and as shown in Figure 3, step is following:
Step 100 adds power amplifier parameter verification word when power amplifier module is produced, and check word and power amplifier parameter are stored among the EEPROM;
The logical schematic that check word and power amplifier parameter leave in the EEPROM is gone into shown in Figure 4; By frequency range the power amplifier parameter is divided into n frequency range; 22 power grade parameters are arranged in each frequency range, and during storage, the checking parameter that total power parameter is carried out the verification generation is stored among the CRC 0; The power parameter of each frequency range is carried out the checking parameter that verification produces be stored in successively among CRC 1 to the CRC n, the checking parameter that the expectation power difference of n frequency range is carried out the verification generation is stored among the CRC n+1.
Step 200 is carried out verification to the power amplifier parameter that reads;
Operate as normal after the base station powers on, dsp chip reads power amplifier parameter and check word among the EEPROM through data/address bus, and the power amplifier parameter that reads is carried out CRC check, and the process of check is as shown in Figure 2, comprises following step:
Step 201 is carried out CRC check to whole power amplifier parameters, and whether the twin check result is identical with the check word CRC0 that reads, and identically explains that then the power amplifier parameter is normal, finishes in advance; Otherwise execution in step 202.
Step 202 is carried out CRC check to n frequency range and difference respectively, and compares with corresponding check word (CRC 1 ~ CRC n+1), preserves the result of each frequency range verification.
Step 300 is found check errors, carries out corresponding compensation deals according to parameter error type (for example the 5th frequency range makes a mistake), and processing procedure is following:
Step 301 judges at first whether the verification of power amplifier parameter exists mistake, if there is mistake, then execution in step 302; Otherwise process ends.
Step 303 judges whether the frequency range that verification is correct, if having, then execution in step 304; Otherwise execution in step 305.
Step 304 is utilized the power amplifier parameter of the correct frequency range x of verification, the power amplifier parameter of each power grade of compensation check errors frequency range y, and the compensation method of each power grade power amplifier parameter is:
Power parameter+frequency range y and x difference under the corresponding grade of frequency range y power amplifier parameter=frequency range x;
Compensate the frequency range power amplifier parameter of other check errors according to this.
Step 306 after above processing, has obtained one group of new power amplifier parameter and has carried out closed power control.
Step 400, through the alarm or the notice form with parameter verification type of error real-time report to managing the backstage.
In the present embodiment,, then think the power amplifier abnormal parameters when finding that check word is inconsistent; On the one hand; Through wrong power amplifier parameter is compensated, make the base station operate as normal, avoid burning out power amplifier and power amplifier because of inactivity or the very low problems such as base station service quit, network index deterioration that make of power; On the other hand, correct and have the correct frequency range parameter situation of verification for the difference verification, all power parameters can obtain correct compensation; But the parameter error serious situation adopts the power amplifier parameter of giving tacit consent to, and transmitting power and actual some gap that requires reporting relevant alarm or notice so that in time can inquire, and are convenient to safeguard and overhaul.
Present embodiment relates generally to the fault detect of the power amplifier parameter of GSM base station, equally also is suitable for the fault detect and the processing of other types parameter.For example, also be suitable for the reading and verification of IQ (Inphase Quadrature, inphase quadrature passage) configuration parameter of zero intermediate frequency transmitter in the inside of base station.
Present embodiment is that example is set forth with device and the implementation method that the GSM base station solves the power amplifier parametic fault, but the invention is not restricted to use at gsm system, and other field and system stand good; For example, WCDMA (Wideband Code Division Multiple Access, WCDMA)); TD-SCDMA (Time Division-Synchronous Code Division Multiple Access; TD SDMA), the base station of LTE systems such as (Long Term Evolution, Long Term Evolutions); Also can further segment some functional parameters, need the electronic equipment of verification when reading applicable to other.
Present embodiment mainly is to adopt segmentation that the power amplifier parameter is carried out verification, can distinguish the parameter error type through verification; Corresponding then type of error is taked compensation or is evaded, and reaches the purpose that does not influence carrier frequency normal transmission power.For the serious carrier frequency of parameter error; Through using acquiescence power amplifier parameter to avoid base station transmitter to be burnt out because of power is excessive, perhaps too for a short time base station service quit so that the network index of making of base station transmitter inactivity or power worsens that consequence avoids burning out power amplifier or network moves back clothes.
The present invention also is suitable for the other types parameter; As long as can carry out segmentation according to function or importance to parameter; Verification such as to the IQ parameter also can be adopted this method of the present invention; The IQ parameter can be divided into different parameter sections according to frequency range and temperature, therefore also can carry out the segmentation verification to it.
