Stating abnormal signal record includes a variety of situations, and such as increased signal record (being designated as newly-increased signal), the signal record deleted (is designated as
Reduce signal), the signal record (being designated as variable signal) that changes of signal intensity or signal name.It should be noted that for
Same signal (having identical wireless identification), repeatedly shows in different target signal list, in fact it could happen that a variety of situations, such as
The signal is newly-increased signal in certain signal gathered list, is variable signal in the signal list of another collection,
It is again reduction signal in the signal list of collection, the same signal under different situations records for different abnormal signals, such as
Signal as newly-increased signal records from as the same signals assignment for reducing signal in different abnormal signals, goes out recording it
It is to separate statistics during the existing frequency.There are n times as newly-increased signal in such as a certain signal, then the signal can as reduction signal
Occur M/P/Y times.
Step S21, obtain the frequency of occurrence of each abnormal signal record in all abnormal signal records；
Server can be comformed multiple terminals collection mass data, and abnormal letter is determined according to echo signal list and original signal list
Number record after, if a certain abnormal signal record only occurred once, in some embodiments, it is also possible to according to this extremely believe
, but in more embodiments, often there are preset times in a certain abnormal signal record in number record renewal original signal list
Afterwards, renewal original signal list is just recorded according to the abnormal signal, the preset times are commonly greater than once, being ten times or ten
More than five times.The setting of the preset times is in order to exclude the interference of factor once in a while, because the wireless device in the confined space can
It can also be opened again after a period of time because some situation temporary closes, or because more barrier equipment temporarily so that eventually
Holding the signal intensity of present position reduces, but the barrier equipment can be removed afterwards, server can be avoided to be caused according to accidentalia
Abnormal signal record renewal original signal list, cause frequent updating feature database, be unfavorable for provide positioning service while, consumption
A large amount of operations and memory source.
Step S22, judge whether that frequency of occurrence is more than the stand-by abnormal signal record of predetermined threshold value；
Step S23, if the stand-by abnormal signal that frequency of occurrence be present more than predetermined threshold value records, the original signal list
Meet update condition；
Step S24, if being more than the abnormal signal of predetermined threshold value in the absence of frequency of occurrence, the original signal list is unsatisfactory for
Update condition, without renewal.
The present embodiment preset times described above are that the frequency is more than predetermined threshold value, and the predetermined threshold value can be write from memory by server
Recognize setting.If terminal send, its be presently in the echo signal list of position, frequency of occurrence be present and be more than predetermined threshold value
Abnormal signal record, then can determine that the original signal list meet update condition, it is necessary to according to the echo signal arrange update
Original signal list；If the abnormal signal for being more than predetermined threshold value in the absence of frequency of occurrence records, the original signal list can determine that
Update condition is unsatisfactory for, without renewal.
It is relative to obtain the echo signal list by contrasting the echo signal list and original signal list for the present embodiment
Recorded in all abnormal signals of original signal list, the frequency that each abnormal signal record occurs is obtained, when frequency of occurrence is more than
During the abnormal signal of predetermined threshold value, judge that the original signal list meets update condition, and then the original signal list is carried out
Renewal, using single abnormal signal as comparison other, rather than using whole signal list as comparison other, can more accurately update spy
Storehouse is levied, meanwhile, predetermined threshold value is set, it is described only when the abnormal signal record that frequency of occurrence is more than the predetermined threshold value be present
Original signal list just meets update condition, can exclude the interference of accidental sexual factor so that renewal is more accurate, it also avoid accidentally
Unnecessary renewal, avoids the wasting of resources caused by sexual factor, is advantageous to the normal operation of whole server/feature database.
Further, wrapped described in step S12 according to the echo signal list update the step of original signal list
Include：
Step S25, obtain the stand-by abnormal signal and be recorded in corresponding signal record to be updated in original signal list, use
The stand-by abnormal signal record replaces the signal record to be updated.
After it is determined that frequency of occurrence be present more than the abnormal signal record of predetermined threshold value, the original signal list meets renewal
Condition, obtain the stand-by abnormal signal and be recorded in corresponding signal record to be updated in original signal list, with described stand-by different
Regular signal record replaces the signal record to be updated.As signal record be present in original signal list：Wireless signal identifies mac
(A), wireless signal strength (- 85dbm)；Echo signal list：Wireless signal mark mac (A), wireless signal strength (-
70dbm).Then directly the signal record in original signal list is updated to：Wireless signal mark mac (A), wireless signal strength (-
70dbm)。
The present embodiment replaces corresponding in original signal list by using frequency of occurrence more than the abnormal signal of predetermined threshold value
Signal record, relative to whole echo signal list replace original signal list, will more accurately can need to update
Data update.
Further, based on first embodiment or second embodiment, in third embodiment of the invention, the step S10
Include before：
