Step 102: set up indoor differentiation database according to the Wi-Fi finger print information of described indoor environment, or the data of Wi-Fi finger print information satisfactory in the Wi-Fi finger print information of described indoor environment are stored in existing indoor differentiation database.

After the Wi-Fi finger print information obtaining the indoor environment uploaded by mobile terminal, if also do not set up indoor differentiation database, the Wi-Fi finger print information first utilizing the indoor environment uploaded by mobile terminal is needed to set up indoor differentiation database, if established indoor differentiation database, then need every predetermined time, data in existing indoor differentiation database are supplemented, the data of new satisfactory Wi-Fi finger print information are stored in existing indoor differentiation database.

Fig. 2 is the method flow diagram of the indoor differentiation database of foundation that first embodiment of the invention provides, as shown in Figure 2: under the condition also not setting up indoor differentiation database, step 102 comprises step 1021a ~ step 1024a:

Step 1021a: the Wi-Fi fingerprint information data of the indoor environment uploaded by mobile terminal is stored in volatile data base;

Step 1022a: the Wi-Fi fingerprint information data in volatile data base is carried out cluster analysis;

Step 1023a: according to the result of cluster analysis, carries out filtration treatment to the Wi-Fi fingerprint information data in volatile data base;

Step 1024a: store the Wi-Fi fingerprint information data after filtering in described volatile data base, set up indoor differentiation database.

Fig. 3 is the method flow diagram data of Wi-Fi finger print information satisfactory in the Wi-Fi finger print information of indoor environment be stored in existing indoor differentiation database that first embodiment of the invention provides, as shown in Figure 3:

Under the condition establishing indoor differentiation database, step 102 specifically comprises step 1021b ~ step 1024b:

Step 1021b: the Wi-Fi fingerprint information data of the indoor environment uploaded by mobile terminal is stored in volatile data base.

Detect through step 101 and determined to be in indoor mobile terminal, the Wi-Fi fingerprint information data of environment residing for collecting is uploaded to server, and the Wi-Fi fingerprint information data of the Wi-Fi fingerprint information data received as indoor environment is stored in volatile data base by server.

Step 1022b: every predetermined time, carries out cluster analysis by the Wi-Fi fingerprint information data in described volatile data base with the Wi-Fi fingerprint information data in described existing indoor differentiation database.

Cluster analysis refers to the analytic process set of physics or abstract object be grouped into as the multiple classes be made up of similar object, the technical method of cluster analysis is used for data of description, weigh the similitude between different pieces of information source, and data source is categorized in different bunches, cluster by Data classification to different classes or bunch, so the object in same bunch has very large similitude, and the object between different bunches has very large diversity.

The required class divided of cluster is unknown.In the process of classification, need not provide the standard of a classification in advance, cluster analysis from sample data, can be classified automatically.The difference of cluster analysis institute using method, usually can obtain different conclusions.Different researcher carries out cluster analysis for same group of data, and the cluster numbers obtained also may not be consistent.

Cluster analysis is a kind of method by data modeling reduced data.Traditional Statistical Clustering Analysis analytical method comprises hierarchical clustering method, decomposition method, addition method, dynamic state clustering, clustering ordered samples, have overlapping cluster and fuzzy clustering, hierarchical clustering, k-means cluster etc.The cluster analysis instrument of k-means, k-central point scheduling algorithm is adopted to be added in many statistics analysis software packages, as SPSS(Statistical Product andService Solutions, statistical product and service solution), SAS(Statistical Analysis System, statistical analysis) etc.

Particularly, because Wi-Fi finger print information comprises the data such as MAC Address, signal strength signal intensity of Wi-Fi signal, therefore carrying out cluster analysis to Wi-Fi finger print information is that the feature such as MAC Address, signal strength signal intensity according to Wi-Fi signal carries out cluster analysis, and the result of final cluster depends on the method that cluster analysis adopts, therefore, when selecting clustering method, in conjunction with actual conditions, should even carry out experiment test to select suitable clustering method.Wherein, the clustering method that embodiments of the invention preferably adopt has levels cluster, k-means cluster etc.

Wi-Fi fingerprint information data in volatile data base is carried out cluster analysis with the Wi-Fi fingerprint information data in indoor differentiation database, on the one hand in order to according to the result of cluster by the data screening of mistake out, particularly, if there is the Wi-Fi fingerprint information data being in environment residing for outdoor mobile terminal in the Wi-Fi fingerprint information data of the indoor environment collected, so same place or near again occur mistake gather possibility can be very little, therefore, when carrying out cluster analysis, the data of mistake and other any data all can not be classified as a class, this just by the data screening of mistake out.On the other hand in order to classify according to Wi-Fi fingerprint information data, the Wi-Fi fingerprint information data in same indoor or adjacent chamber is categorized in together, prepare to set up index later.By the feature such as MAC Address, signal strength signal intensity of cluster analysis according to Wi-Fi signal, classified by the Wi-Fi fingerprint information data of indoor environment, each sorted group just can adopt common feature (such as identical MAC Address etc.) as the mark of index.

Step 1023b: according to the result of described cluster analysis, carries out filtration treatment to the Wi-Fi fingerprint information data in described volatile data base.

Because sometimes can error be there is when differentiating in the Wi-Fi fingerprint information data of indoor environment, such as, sometimes fixing socket is also had in outdoor, can for the fixing charging of mobile terminal, or there is mistake when judging mobile terminal charged state, or pass through mobile terminal the user of outdoor, be in situations such as indoor to server acknowledge, make server by mistake by not residing for the mobile terminal of indoor the Wi-Fi fingerprint information data of environment be used as the Wi-Fi fingerprint information data being in environment residing for indoor mobile terminal and process, therefore, the Wi-Fi fingerprint information data of the indoor environment mobile terminal that server obtains can not uploaded directly carries out processing and using, first to carry out a filter operation to information data.

Wherein, step 1023b comprises step a ~ c:

Data in volatile data base are added corresponding sorted group by step a: according to the classification of cluster analysis.

Adopt suitable clustering algorithm, cluster analysis is carried out to data, after classifying according to the feature of data, data in volatile data base are joined corresponding sorted group, multiple sorted group can be obtained like this, wherein, sorted group can be the original sorted group of indoor differentiation database, also can be the newly-established sorted group of data in volatile data base.

Step b: judge whether the number of Wi-Fi fingerprint information data element in each sorted group is less than the first predetermined threshold value.

Step c: the Wi-Fi fingerprint information data number of Wi-Fi fingerprint information data element be less than in the volatile data base in the sorted group of the first predetermined threshold value is deleted.

For each sorted group, obtain the number of Wi-Fi fingerprint information data element in sorted group, this number is compared size with the first predetermined threshold value, first predetermined threshold value can set with experience as required, such as, arranging the first predetermined threshold value is 2, when in certain sorted group, the number of Wi-Fi fingerprint information data element is less than 2, is deleted by Wi-Fi fingerprint information data in this sorted group.

Step 1024b: the Wi-Fi fingerprint information data in described volatile data base after filtering is stored in described existing indoor differentiation database.

Every predetermined time, Wi-Fi fingerprint information data in volatile data base is carried out cluster analysis together with the Wi-Fi fingerprint information data in indoor differentiation database, then deletion action is carried out to the data filtered out, remaining data are stored in indoor differentiation database, and are stored in corresponding sorted group by classification.

In addition, according to the data message in indoor Wi-Fi fingerprint information data storehouse, index is set up.

In a database, index is a kind of database structure relevant with table, and it can make the SQL statement corresponding to watch perform faster.The effect of index is equivalent to the catalogue of books, can find required content fast according to the page number in catalogue.When show in have record in a large number time, inquire about to his-and-hers watches, the first search information mode entirely shows search, all records are taken out one by one, contrast one by one with querying condition, then return the record satisfied condition, do like this and can consume mass data storehouse system time, and cause a large amount of magnetic disc i/o to operate; The second sets up index exactly in table, then finds the index value meeting querying condition in the index, is equivalent to the page number finally by the ROWID(preserved in the index) find record corresponding in table fast.Index provides the pointer of the data value in the appointment row pointing to and be stored in table, then sorts to these pointers according to the clooating sequence of specifying, greatly accelerates the retrieval rate of data.Therefore, setting up index can improve search speed greatly, raises the efficiency.

Step 103: the Wi-Fi finger print information obtaining environment residing for mobile terminal described to be determined that mobile terminal to be determined uploads.

The Wi-Fi fingerprint information data of environment residing for it is uploaded by mobile terminal to be determined, received by server, in a kind of execution mode of the embodiment of the present invention, for mobile terminal, every predetermined time, gather the Wi-Fi finger print information of environment residing for current described mobile terminal, and by the Wi-Fi finger print information active upload that collects to server.

In the another kind of execution mode of the present embodiment, server sent request to mobile terminal every predetermined time, after mobile terminal receives request, the Wi-Fi finger print information of environment residing for the current described mobile terminal collected was uploaded to server.

Step 104: the Wi-Fi fingerprint information data stored in the Wi-Fi finger print information of environment and described indoor differentiation database residing for described mobile terminal to be determined differentiates whether mobile terminal to be determined is positioned at indoor.

Fig. 4 be first embodiment of the invention provide differentiate whether mobile terminal to be determined is positioned at indoor method flow diagram according to indoor differentiation database, as shown in Figure 4:

Step 1041: search inquiry and current Wi-Fi fingerprint information data to be determined have the set of metadata of similar data of common trait in indoor differentiation database.

Wherein, current Wi-Fi fingerprint information data to be determined is the Wi-Fi fingerprint information data of the current residing environment of mobile terminal to be determined.According to Wi-Fi fingerprint information data (such as Wi-Fi list, MAC Address etc.) in the index of current Wi-Fi fingerprint information data to be determined and indoor differentiation database or indoor differentiation database, in indoor differentiation database, carry out search inquiry, find and have the set of metadata of similar data of common trait (having the Wi-Fi finger print information of same item in such as Wi-Fi list, MAC Address) with current Wi-Fi fingerprint information data to be determined.If find the set of metadata of similar data having common trait with current Wi-Fi fingerprint information data to be determined in indoor differentiation database, so Wi-Fi fingerprint information data of environment near the current mobile terminal to be determined of this data representation, at this moment can't judge that whether mobile terminal to be determined is in indoor, also to further judge, because possibility mobile terminal is in the outdoor near certain indoor.

Step 1042: the similarity calculating all described set of metadata of similar data and current Wi-Fi fingerprint information data to be determined.

Particularly, when mobile terminal is when indoor, the Wi-Fi fingerprint information data of environment residing for described mobile terminal will be more close with the Wi-Fi fingerprint information data of this indoor environment, similarity will be higher, at this moment, we need the similarity of the Wi-Fi fingerprint information data calculating environment residing for all described set of metadata of similar data and current described mobile terminal to be determined, thus do further to judge according to similarity.The methods such as wherein, embodiments of the invention preferably adopt COS distance, Euclidean distance, common factor ratio carry out the calculating of similarity.

Step 1043: by all described similarities respectively compared with the second predetermined threshold value.

Particularly, first will rule of thumb or experiment set a predetermined threshold value to similarity, then by calculated similarity compared with this predetermined threshold value.

Step 1044: when described similarity is greater than the second predetermined threshold value, judges that described mobile terminal to be determined is positioned at indoor.

First, there is no search inquiry to when having a set of metadata of similar data of common trait with current Wi-Fi fingerprint information data to be determined when differentiating indoor in database, illustrating that distance of mobile terminal indoor to be determined are comparatively far away, therefore can judge that mobile terminal to be determined is in outdoor.

When all similarities are all not more than the second predetermined threshold value, illustrate that the difference of the Wi-Fi fingerprint information data of Wi-Fi fingerprint information data to be determined and indoor environment is comparatively large, judge that mobile terminal to be determined is in outdoor.When having at least a similarity to be greater than predetermined threshold value, judge that mobile terminal to be determined is in indoor.

When server judges that mobile terminal is behind indoor, result is pushed to described mobile terminal, or carries out message push according to this result, also can carry out corresponding switching according to result to the locate mode of described mobile terminal.

In sum, the general principle of the first embodiment of the present invention as shown in Figure 5, be in several mobile terminals of indoor diverse location, the Wi-Fi finger print information of indoor environment residing for it is gathered, by collect its residing for the Wi-Fi finger print information of indoor environment be uploaded to server, and the Wi-Fi fingerprint information data of indoor environment to be stored in volatile data base 301.When also not setting up indoor differentiation database 302, cluster analysis is carried out to the data in volatile data base 301, erased noise data, and utilize satisfactory data remaining in volatile data base 301 to set up indoor differentiation database 302; When setting up indoor differentiation database 302, all data in volatile data base 301 and existing indoor differentiation database 302 are put together and carries out cluster analysis, erased noise data, and satisfactory data remaining in volatile data base 301 are stored in existing indoor differentiation database 302, data in indoor differentiation database 302 are supplemented, makes the data in indoor differentiation database 302 more reliable.
