Signaling message containing the wifi information also contains the five-tuple information corresponding with the wifi information；The five-tuple letter
Breath includes IP address, user port number, server ip address, server end slogan, protocol type.
Concentrate and encapsulating signalling messages (S2)：The signaling message that each gap-bridging device is obtained is converged to one by concentrating gateway
Rise, and every signaling message is packaged into packet.Because collection may use multiple tap, multiple optical splitters, multiple high resistants
All of signaling, is brought together treatment by head.Concentration is can in order to save transmission equipment below, transmission bandwidth and guarantee
By transmission.
It is the reliable transmission of the signaling that guarantee is collected, every signaling message is all packaged, that is, constructs a data
Bag.Packet includes packet header and message body.
Packet header is used to record the time of origin of the current signaling message for collecting, and one sequence number of distribution is used for record and believes
The order and sum of message are made, and records the information such as collecting device number.Because collecting device is not same with signaling resolution equipment
Platform machine, transmit process there may be part it is out of order (signaling message that may collect below has first been sent to analyzing device, first
The signaling message for collecting on the contrary below be just sent to analyzing device) situation, it is exactly to ensure letter to increase these header packet informations
Message is made reliably to transmit in order.Message body contains latitude and longitude information or wifi information as the load of packet.
Parse and associate signaling message (S3)：By background server by the latitude and longitude information in each signaling message, wifi
Information, five-tuple information analysis are out；And wifi information and latitude and longitude information the combination pass the identical five-tuple information of each correspondence
Connection.
As shown in figure 3, in S3, wifi information analysis and processing procedure are as follows：
S311：Filter out the signaling message containing wifi information；
S312：The header packet information of the signaling message containing wifi information is peeled off, retains the signaling message containing wifi information
Five-tuple information, application layer header packet information, message body；
S313：The server in application layer header packet information and five-tuple information according to the signaling message containing wifi information

S314：The message body of the signaling message containing wifi information is decoded using selected coding/decoding method, is obtained
Wifi information.
As shown in figure 4, in S3, after S314 also comprising latitude and longitude information parsing and processing procedure, it is as follows：
S321：Filter out the signaling message containing latitude and longitude information；
S322：The header packet information of the signaling message containing latitude and longitude information is peeled off, retains the signaling containing latitude and longitude information
The five-tuple information of message, message body；
S323：By the signaling message containing latitude and longitude information and the letter containing wifi information of the identical five-tuple information of correspondence
Message is made to combine association；
S324：According to the application layer header packet information and server ip address of the signaling message accordingly containing wifi information
The coding/decoding method of the message body of the selected signaling message containing latitude and longitude information；
S325：The message body of the signaling message containing latitude and longitude information is decoded using selected coding/decoding method, is obtained
Learn from else's experience latitude information.
The wifi information of nearly all software is not transmission, the latitude and longitude information with wifi information match in plain text
Major part is not transmission in plain text, in the message body that they are typically placed on http protocol in the form of the binary code stream after encryption.
It is also upper and lower in same packet data protocol even if these wifi information and latitude and longitude information be not in same signaling message
Wen Zhong, is occur in pairs.HTTP associations are placed on after be able to being encrypted with the latitude and longitude information of wifi information match except those
In the message body of view, also some independent latitude and longitude informations (are only individually passed through i.e. in block data protocol context
Latitude information, does not have matching WIFI information), most of this kind of latitude and longitude information can be placed on the message header of http protocol
In, it is transmission in plain text.Wifi information and latitude and longitude information typically all can be using such as BASE64 encryptions, XOR encryption, AES
The methods such as ecb mode encryption, AES CBC mode encryptions, ZIP compression, GZIP compressions are treated.Correspondence is selected for every money software
Coding/decoding method, correctly reduce prime information.
Signaling message is decoded just as tearing an envelope for plurality of layers open, is in layer peeled off, so two kinds of letters of solution
Information is made to be required for peeling off header packet information.Five-tuple information is the matching key for associated packet data protocol contexts, so
Two kinds of information of solution are also all to need to solve and retain five-tuple information.
Although server ip address is every signaling message having, the header packet information one with mark software information
As only occur once, generally with wifi information in same signaling message, so wifi information and latitude and longitude information are first passed through
Five-tuple is associated, and two kinds of information after having associated just can be with shareware information, with corresponding coding/decoding method to containing longitude and latitude
The message body of the signaling message of information is decoded.
The combination for realizing signaling message by background server is associated, by five-tuple information the wifi information for parsing
Associated with latitude and longitude information combination；Then the information combined after association is sent in storage server.Wifi information and warp
Latitude information is possible in same signaling message, it is also possible to not in same signaling message, when not in same letter
When making in message, association is combined using five-tuple information, the signaling message with identical five-tuple is associated together, its
In decode the latitude and longitude information come and wifi information is also synthesized together, as wifi fingerprints initial data.
Storage related information (S4)：The wifi information and latitude and longitude information after each combination association are entered by storage server
Row storage, in case information inquiry and further treatment.
The present invention installs special software, it is only necessary to install equipment concentratedly without manual site's test without terminal user
Achieve that automatic business processing；The present invention installs software and collect with equipment certain relation, but the present invention does not rely on software-type
Number.
As shown in Figure 10, it is the schematic diagram of Application Example of the invention.Such as A softwares and B softwares can be realized
Wifi finger print datas are collected, but A softwares belong to A producers, and B softwares belong to B producers, and the data that A and B producers are collected into may
Have the same, it is also possible to have different, and the present invention can be realized across across the producer collection of software, realize message complementary sense, information can be more
It is accurate and complete.Because A producers can only be collected into the data for being mounted with A manufacturer softwares, B producers can only be collected into and be mounted with B factories
Family's software, due to the relation of occupation rate of market, the information that A producers may collect in A areas is more complete, and B producers may collect in B areas
Information it is more complete.And this method can simultaneously collect the information of A and B, i.e. A areas and B areas all information is complete.

Major part is not transmission in plain text, in the message body that they are typically placed on http protocol in the form of the binary code stream after encryption.
It is also upper and lower in same packet data protocol even if these wifi information and latitude and longitude information be not in same signaling message
Wen Zhong, is occur in pairs.HTTP associations are placed on after be able to being encrypted with the latitude and longitude information of wifi information match except those
In the message body of view, also some independent latitude and longitude informations (are only individually passed through i.e. in block data protocol context
Latitude information, does not have matching WIFI information), most of this kind of latitude and longitude information can be placed on the message header of http protocol
In, it is transmission in plain text.Wifi information and latitude and longitude information typically all can be using such as BASE64 encryptions, XOR encryption, AES
The methods such as ecb mode encryption, AES CBC mode encryptions, ZIP compression, GZIP compressions are treated.Correspondence is selected for every money software
Coding/decoding method, correctly reduce prime information.
Signaling message is decoded just as tearing an envelope for plurality of layers open, is in layer peeled off, so two kinds of letters of solution
Information is made to be required for peeling off header packet information.Five-tuple information is the matching key for associated packet data protocol contexts, so
Two kinds of information of solution are also all to need to solve and retain five-tuple information.
Although server ip address is every signaling message having, the header packet information one with mark software information
As only occur once, generally with wifi information in same signaling message, so wifi information and latitude and longitude information are first passed through
Five-tuple is associated, and two kinds of information after having associated just can be with shareware information, with corresponding coding/decoding method to containing longitude and latitude
The message body of the signaling message of information is decoded.
Association is combined in realization to signaling message, by five-tuple information the wifi information and latitude and longitude information for parsing
Combination is associated；Then the information combined after association is sent in storage server.Wifi information has with latitude and longitude information can
Can be in same signaling message, it is also possible to not in same signaling message, when not in same signaling message, make
Association is combined with five-tuple information, the signaling message with identical five-tuple is associated together, wherein decoding what is come
Latitude and longitude information and wifi information are also synthesized together, as wifi fingerprints initial data.
