detailed description

In each embodiment of the present invention, by obtaining the key information record of the data service of the mobile phone terminal, the IMEI and terminal type information of the new network terminal can be quickly obtained, and the IMEI and terminal model information can be found out by analyzing the URL in the signaling. Correspondence, improve the success rate of automatic matching through multiple filtering and verification.

FIG. 1 is a flow chart of a method for rapidly completing a terminal information database provided by an embodiment of the present invention. As shown in Figure 1, the method provided in this embodiment can be executed by a device that quickly completes the terminal information database, and the method provided in this embodiment can specifically include:

Step 101. Acquire key information records of data services.

In this step, the key information records including the data service used by the user can be extracted by collecting and decoding the original code stream, and the data can be collected from the Gb interface, IuPS interface, Gn interface or S1-U interface.

Step 102 , parse out all Uniform Resource Locator URL information using HTTP services from the key information records.

Among the collected data, when a user goes online, some browsers and business APP software will automatically report the key information of the user, such as mobile phone number, IMSI, IMEI, terminal type, system type and corresponding version information, etc.; such information may appear in the URL of the HTTP record, and the recorded content of the URL may be as follows:

/config/start? appversion=3.9.5&channel=102&city_id=1&datatype=101&imsi=460021038003510imageType=2&imei=358584057426497&maptype=soso&model=iPhone6&os=8.4&sig=ba9070aef4fad4af91a611aW6492d2adgZRBotok5CHOxRedbk5CHBotok

The URL in the above example contains key information such as IMSI, IMEI, terminal brand, terminal model, and system version, which can be used to determine terminal information.

Step 103. Obtain key URL information including terminal information from the URL information and save it.

In this step, it is first necessary to preliminarily filter the URL information, that is, obtain URL information containing preset keywords from the URL information, for example, sort all URL information according to "imei", "IMEI", "Imei " and other keywords to search, as long as the URL information contains such keywords, the record will be screened out for the next step of filtering.

Secondly, perform secondary analysis on the information that is initially filtered out, that is, use keyword matching to obtain the key URL information from the URL information containing preset keywords; the key URL information includes the terminal's IMEI identification information, Terminal brand information, terminal model information and system version information.

Step 104, extracting IMEI identification information from the stored key URL information.

Specifically, information such as IMEI identification information, terminal brand, terminal model, and system version is identified through keyword matching; since different data services have different keywords, while providing as many keywords as possible to filter, in order to avoid errors Identify the situation, use business identification to judge whether there may be key information such as imei and terminals in the current business; for example, for HTTP recorded as user registration or Weibo access, it is more credible to have IMEI and other information in the URL; for browsing news business HTTP, Even if there is information such as IMEI in it, it will not be extracted.

In this embodiment, when the IMEI identification information is identified from the URL information of the keyword, a first formula is used to verify the validity of the IMEI identification information;

The first formula is:

Among them, the u(x) function is used to determine the nature of the service accessed by the user by judging the HOST domain in the HTTP message, and verify the validity of the IMEI identification information; the r(y) function is used to judge the URL in the HTTP message The domain identifies user behavior characteristics, and verifies the validity of the IMEI identification information; the IMEI identification information that passes the validity verification is used as the finally extracted IMEI identification information.

Specifically, if f(x, y)=0, the IMEI is an invalid IMEI, and if f(x, y)=1, the IMEI is a valid IMEI.

The u(x) function is used to judge the nature of the user's access service by judging the HOST field in the HTTP message, such as whether it is Weibo access, navigation, taxi and other business characteristics to identify the validity of the IMEI, x represents host; when x Belongs to the set of trusted hosts {"api.udache.com", "m.simba.taobao.com", "vectors.map.qq.com, api.m.taobao.com", "andmlbf.tj.ijinshan.com ", "api.diditaxi.com.cn", "wx.houyi.baofeng.net", "notice.diditaxi.com.cn", "api.app.i.sogou.com", "common.diditaxi.com .cn",...}, u(x)=1.

The r(y) function is used to identify user behavior characteristics by judging the url field in the HTTP message, such as registration, login, privacy reporting, etc., so as to judge the validity of the IMEI, and y stands for url. When y contains keyword set {"mobile", "login", "register", "Register", "sign=", "config", "report", "start_time=",...} When one or several items, r(y)=1.

The values of u(x) and r(y) can only be 0 or 1. Only when u(x)=0 and r(y)=0, the IMEI is an invalid IMEI; otherwise, it is a valid IMEI.

In practical applications, alias matching can also be used to improve the matching degree of IMEI, terminal brand, terminal model, and system version. Alias refers to a digital description of the terminal model. For example, an alias corresponding to iphone5s is called A1530.

The specific implementation method is: filter out the records that have IMEI identification information and alias information but cannot distinguish the terminal model, the IMEI identification information is 35878705****375, the alias is A1530, but the terminal model cannot be distinguished, as shown in Table 1 .

Table I

IMEI identification information Terminal brand information Terminal model information alias Network Type Information 35878705****375 A1530

Match the same record as the TAC in the record. The record should contain IMEI identification information, terminal brand information, terminal model information, alias, and network type information. For example, the IMEI identification information is 35878605****497, and the alias is A1530. The terminal brand information is Apple, the terminal model information is Iphone5s, and the network type information is TDD-LTE, as shown in Table 2.

Table II

IMEI identification information Terminal brand information Terminal model information alias Network Type Information 35878605****497 apple Iphone5s A1530 TDD-LTE

Complete the above records according to the found TAC, terminal brand information, terminal model information, alias, and network type information, then the IMEI identification information is 35878705****375, the terminal brand information corresponding to the terminal with the alias A1530 is Apple, and the terminal The model information is Iphone5s, and the network type information is TDD-LTE, as shown in Table 3.

Table three

Step 105, analyzing the consistency between the IMEI identification information and the terminal model, and completing the terminal information database according to the analysis results.

In practical applications, some terminals can modify the terminal name, that is, the terminal model. Most Android terminals support the free modification of the terminal name. If you do not deal with it, you may recognize a terminal as a terminal of another brand or another model of the brand.

Extract the first 8 digits of IMEI identification information, that is, TAC, and use the mapping relationship between TAC and terminal model to make statistics. When the TAC mapping rate of a certain model reaches the threshold, it can be considered that the TAC corresponds to the terminal model one-to-one, and then according to the terminal model The relationship between model and brand, network type and other parameters complements other parameter information, and all TAC analysis is realized according to this method.

Specifically, extract the TAC of the IMEI identification information, and calculate the TAC mapping rate; the TAC mapping rate is the ratio of the cumulative number of times of the terminal model corresponding to the TAC to the cumulative number of times of all terminal models corresponding to the TAC ; When the TAC mapping rate reaches the preset threshold, determine that the TAC corresponds to the terminal model with the most corresponding times; match the determined terminal model and the IMEI identification information with the information in the existing terminal information database, If the matching fails, add the terminal information corresponding to the IMEI identification information; if the matching is successful, verify the consistency between the terminal information in the existing terminal information database and the IMEI identification information.

When verifying the consistency between the terminal information in the existing terminal information database and the IMEI identification information, formatting and amending the IMEI identification information, extracting the TAC in the formatted and amended IMEI identification information, The TAC is queried in the existing terminal information database to perform consistency verification.

It should be noted that only when the IMEI identification information, terminal brand information, terminal model information, and supported network standard parameters are all the same, can the consistency verification be considered successful; otherwise, it needs to be identified and then manually verified.

The technical solution provided by this embodiment can quickly acquire the terminal information of a mobile phone terminal newly connected to the network, and automatically complete the terminal information database.
