A kind of method of priori frequency sequence is embodiments provided, as shown in Fig. 2 including：
201st, terminal obtains the target component of each the priori frequency in N number of priori frequency of terminal maintenance, a priori The target component of frequency includes at least two parameters in three below parameter：The normalized crosscorrelation value of the priori frequency, should The RSSI of priori frequency, the resident number of times of the success of the priori frequency in preset time period.
Wherein, the normalized crosscorrelation value of a priori frequency is referred to according to the time domain local signal of master sync signal to this The time domain receiving data of priori frequency is normalized the value that computing cross-correlation is obtained, and master sync signal is used for terminal and network system System carries out Time and Frequency Synchronization, and N is the integer more than 1.
N number of priori frequency is all priori frequencies for safeguarding or part priori frequency in terminal.
Terminal can adopt method of the prior art to obtain the RSSI of priori frequency, and RSSI refers to the day in certain bandwidth Line mouth power, generally, the RSSI of priori frequency is bigger, and signal is stronger, and terminal searches out cell on the priori frequency Probability is bigger.
Terminal can carry out statistics by the resident number of times of success to each priori frequency in preset time period and obtain pre- If number of times is resident in each success of priori frequency in preset time period in the time period, the embodiment of the present invention is to preset time period Length be not especially limited.The resident number of times of the success of one priori frequency is bigger, illustrates there is covering on the priori frequency Cell probability it is bigger.
Terminal can adopt normalized crosscorrelation formula to calculate the normalized crosscorrelation value of priori frequency, generally, When the normalized crosscorrelation value of priori frequency is bigger, probability of the priori frequency for the true frequency of LTE network system cell Bigger, the received signal quality of the priori frequency is also better.
Hereinafter, the process that the normalized crosscorrelation value of priori frequency is obtained to terminal is illustrative.
Physical Cell Identifier (Cell ID) in LTE system has 504 kinds of possible values, and from 0 to 503,504 physics are little Area's mark is divided into 168 groups, 3 per group.
Specifically,Wherein,That is Physical Cell Identifier,The group # of packet is represented, There are 168 kinds of values, from 0 to 167,Numbering in expression group, has 3 kinds of values, from 0 to 2, each Physical Cell Identifier correspondence Numbering in only one group number and group.LTE system utilizes PSS and auxiliary synchronous signals (Secondary Synchronization Signal, abbreviation SSS) complete cell searching, base station can all send PSS per 5ms, PSS frequency-region signals byUniquely determine, altogether 3.
Terminal is attempted receiving the data that base station sends after powering, on priori frequency, if deposited on the priori frequency In LTE system cell, then the data that base station sends just include PSS within the 5ms times, if do not deposited on the priori frequency In LTE system cell, then the data received within the time of 5ms just do not include PSS, terminal can utilize the PSS of storage The data that time domain local signal is received on the priori frequency to terminal calculate the priori using PSS normalized crosscorrelation formula The normalized crosscorrelation value of frequency, the normalized crosscorrelation value of the priori frequency are higher, show that the PSS time domains of terminal storage are local The data that signal is received on the priori frequency to terminal are more similar.
Specifically, the normalized crosscorrelation value calculating method of a priori frequency f is as follows：
Wherein, NRFor the reception antenna number of terminal, i is antenna index, for example, NR=2, i=0,1.
riN () is with f as frequency, the time domain receiving data that reception antenna i is received is filtered through 1.4MHz wave filter Data after ripple process, D are the sampled point number at least in the 5ms time periods.
Be based onIt is determined that PSS time domain local signal,Sequence length be N.Table ShowComplex conjugate.
L be bySequence length be divided into M sections after, per section of sequence length, L=N/M, for example, N=128, M= 2, then L=N/M=64.L is adjusted by way of M numerical value is set, is calculated when M is not equal to 1Can allow Larger range of frequency deviation, for M=1, M is not equal to calculated when 1Precision it is higher.
It should be noted thatSequence length N and sampled point number D be intended to match with sample frequency, typically In the case of, the PSS of LTE system sends the cycle for 5ms, therefore, D is generally the sampled point number in the 5ms time periods, in sampling frequency When rate is 1.92MHz, N=128, sampled point number D are 9600.
Due to each PSS frequency-region signal byUniquely determine, therefore, terminal is mutual in the normalization for carrying out priori frequency During the calculating of pass, needs cross-correlation calculation is normalized to 3 PSS sequences respectively, then choose maximum as with this The corresponding normalized crosscorrelation value of priori frequency.
Phase between time domain local signal of the data received on the priori frequency of non-LTE system due to terminal with PSS It is inevitable little like spending, therefore, when the normalized crosscorrelation value of priori frequency is bigger, the priori frequency is LTE network system cell True frequency probability it is bigger.If in addition, include PSS in receiving data of the terminal on priori frequency, the receiving data And the size of the normalized crosscorrelation value between the time domain local signal of PSS can be also affected by received signal quality, letter is received Number quality is better, and normalized crosscorrelation value is bigger, therefore, when the normalized crosscorrelation value of priori frequency is bigger, the priori The received signal quality of frequency is also better.
Frequency as non-LTE system cell is there may be in priori frequency, for example, global system for mobile communications (Global System for Mobile communication, abbreviation GSM) system cell frequency, Wideband-CDMA (Wideband Code Division Multiple Access, abbreviation WCDMA) system cell frequency etc., generally, The transmission power of non-LTE system signal is both greater than the transmission power of LTE system signal, therefore, using method of the prior art In the ranking results for obtaining, before the priori frequency of non-LTE system can come the priori frequency of LTE system, so can prolong significantly Long LTE system cell search time.And before if the alias point that there is business datum comes the true frequency of LTE system cell, LTE system cell search time can equally be extended.And according to above-mentioned analysis, if wrapping in target component in the embodiment of the present invention The normalized crosscorrelation value of priori frequency is included, then can be determined in priori frequency according to the normalized crosscorrelation value of priori frequency Frequency and the frequency for LTE system cell is the bigger frequency of probability of true frequency.
