Example one
Fig. 2 is a flowchart of a geographic position determining method according to an embodiment of the present invention, where the method may be performed by a geographic position determining apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a terminal such as a mobile terminal or a server. As shown in fig. 2, the method includes:
Illustratively, a GPS positioning module is configured inside the mobile terminal, and longitude and latitude information of a location where the mobile terminal is located may be acquired through the GPS positioning module. The GPS positioning method is generally accurate and can be positioned in countries and specific cities, but the reported latitude and longitude information may be wrong, such as GPS drift.
An access Network Mobile Country Code (NETMCC) is used to indicate a Country to which a Mobile Network currently accessed by the Mobile terminal belongs. The normal operation of the mobile terminal generally depends on the service provided by the mobile network operator, and the functions of conversation, internet surfing and the like can be realized by accessing the network of the mobile network operator. Generally, the mobile terminal can access the mobile network of the country to which the SIM card belongs, and when the mobile terminal is located abroad, the mobile terminal can access the mobile network of other countries without replacing the SIM card, generally, two operators in different countries are required to sign a bilateral roaming agreement, the user of the operator is allowed to roam to the network of the domestic operator with the signed agreement, and the operator with the signed agreement is allowed to roam to the network of the operator. Thus, after accessing the mobile network, the mobile terminal may obtain the country to which the currently accessed mobile network belongs through a built-in Application Programming Interface (API), that is, obtain NETMCC. Since NETMCC corresponds to a mobile network of one country, it can be localized to a country.
The MCC (Mobile Country Code, also called Mobile signal Country Code) has its resources uniformly distributed and managed by the International Telecommunications Union (ITU), and uniquely identifies the Country to which the Mobile subscriber belongs, which is 3 digits in total, for example, 460 digits in china. A Subscriber Identity Module (SIM) card is generally installed in the Mobile terminal, an International Mobile Subscriber identity Number (IMSI) is stored in the SIM card, the IMSI is a mark for distinguishing a Mobile Subscriber, the total length does not exceed 15 bits, and the MCC is included in the IMSI. In the embodiment of the application, the mobile terminal can obtain the MCC by reading the IMSI in the SIM card. Since the MCC may identify the country to which the mobile subscriber belongs, it may be located to the country.
The IP address information may be generally obtained in a Wi-Fi manner or a General Packet Radio Service (GPRS) manner, and for example, may be queried using an IP address query API interface provided by a web portal such as Tencent or Xinfeng. The country and city can be located according to the IP address information.
For example, after obtaining the positioning information, the mobile terminal may upload the positioning information to the server in the embodiment of the present invention, and the server receives the positioning information reported by the mobile terminal, so as to determine the current geographic position of the mobile terminal. The mobile terminal can also be used for determining the current geographic position by itself after acquiring the positioning information.
Illustratively, for the longitude and latitude information, a prestored longitude and latitude library can be queried to obtain a corresponding geographic position, and then an identification result corresponding to the longitude and latitude information is obtained, wherein the result generally comprises a country and a city. The corresponding country is determined from NETMCC, so the identification corresponding to NETMCC typically includes a country. The corresponding country is determined according to the MCC, so the corresponding identification result of the MCC generally includes the country. For the IP address information, a pre-stored IP library can be inquired to obtain a corresponding geographic position, and then an identification result corresponding to the IP address information is obtained.
And 203, determining the corresponding actual geographic position of the mobile terminal based on the consistency of the identification result.
In the related art, the identification of the geographic location corresponding to the mobile terminal is generally performed based on a single dimension, such as GPS positioning or IP address positioning, and when the latitude and longitude information of the GPS or the IP address information is wrong, the identification result is inaccurate. The geographic location may include, among other things, a country, or a country and a city.
In the embodiment of the application, at least three kinds of positioning information are combined, so that the actual geographic position corresponding to the mobile terminal can be more accurately determined. For example, the adopted preset rule may be that corresponding recognition results are respectively determined according to the positioning information, and the recognition result with the highest consistency is determined as the final recognition result, that is, the geographic position included in the recognition result with the highest consistency is determined as the actual geographic position corresponding to the mobile terminal. For example, the positioning information includes longitude and latitude information, NETMCC, MCC, and IP address information, and the geographic locations included in the corresponding identification results are beijing, china, korea, and tokyo, japan, respectively, and it can be determined that the actual geographic location corresponding to the mobile terminal is china or beijing, china, because the consistency of the identification result of "china" is the highest. Of course, other preset rules may also be adopted to determine the actual geographic location corresponding to the mobile terminal based on the consistency of the recognition results.
The geographic position determining method provided by the embodiment of the application obtains the positioning information of the mobile terminal, wherein the positioning information comprises at least three of longitude and latitude information, access network country code NETMCC, mobile country code MCC and internet protocol IP address information which are obtained by a GPS positioning module of the mobile terminal, the corresponding identification results are respectively determined according to the positioning information, and the actual geographic position corresponding to the mobile terminal is determined based on the consistency of the identification results. By adopting the technical scheme, the dimensionality of the geographic position determination is improved, and the technical effect of improving the accuracy of the geographic position determination result can be achieved.
On the basis of the embodiment, the application scene of the interaction between the server and the mobile terminal can be further optimized. Illustratively, the acquiring the positioning information of the mobile terminal includes: and receiving the positioning information reported by the mobile terminal. The advantage of this arrangement is that the server has greater computing power and can improve the efficiency and accuracy of determining the actual geographic location. Further, after the determining the actual geographic location corresponding to the mobile terminal based on the consistency of the identification result, the method further includes: and sending the actual geographic position to the mobile terminal.

Illustratively, two recognition results are primary recognition results, and the other recognition results are secondary recognition results; the determining the actual geographic location corresponding to the mobile terminal based on the consistency of the identification results comprises: and when the geographic positions corresponding to the two main identification results are inconsistent, determining the actual geographic position corresponding to the mobile terminal by referring to the secondary identification result. This has the advantage that the actual geographical position can be determined with priority by the primary recognition result, and when there is a divergence, the actual geographical position can be determined more accurately with reference to the secondary recognition result.
Optionally, as shown in fig. 3, the method includes:
Optionally, in this embodiment of the application, the positioning information may also have no MCC or no IP address information, that is, the positioning information may also include longitude and latitude information, NETMCC, and MCC acquired by the mobile terminal based on the GPS positioning module, or include longitude and latitude information, NETMCC, and IP address information acquired by the mobile terminal based on the GPS positioning module. Through research and practice of the inventor, the longitude and latitude information acquired based on the GPS positioning module and the identification result corresponding to NETMCC are relatively accurate, so that the technical scheme provided by the embodiment of the application preferentially comprises the two positioning information, and in addition, the identification result corresponding to the longitude and latitude information is higher in accuracy compared with the identification result corresponding to NETMCC. Optionally, the identification result corresponding to the longitude and latitude information acquired based on the GPS positioning module is a main identification result, and the identification result corresponding to the NETMCC is a main identification result.
Illustratively, a longitude and latitude library can be stored in the server, the library comprises a corresponding relation between longitude and latitude and a geographic position, the corresponding relation can exist in the form of a corresponding table and the like, the longitude and latitude library can be inquired according to longitude and latitude information, a first identification result is obtained, the first identification result generally comprises a country and a city, and when the longitude and latitude information is null or abnormal conditions such as format errors occur, the first identification result is null and does not comprise the geographic position. The corresponding country can be determined according to NETMCC, so the second identification result generally includes the country, and when NETMCC is empty or abnormal conditions such as format errors occur, the second identification result is empty and does not include the geographic location. The third identification result generally includes the country, and when the MCC is empty or an abnormal condition such as a format error occurs, the second identification result is empty and does not include the geographic location. The server can store an IP library, the IP library comprises a corresponding relation between the IP address and the geographic position and can exist in the form of a corresponding table and the like, the IP library can be inquired according to the IP address information, a fourth identification result is further obtained, the fourth identification result generally comprises a country and a city, and when the IP address information is empty or abnormal conditions such as format errors occur, the fourth identification result is empty and does not comprise the geographic position.
Optionally, when the positioning information includes longitude and latitude information, NETMCC, and MCC acquired by the mobile terminal based on the GPS positioning module, the identification result in this step includes a first identification result, a second identification result, and a third identification result; when the positioning information includes latitude and longitude information, NETMCC and IP address information acquired by the GPS-based positioning module of the mobile terminal, the identification result in this step includes a first identification result, a second identification result and a fourth identification result.

Optionally, the actual geographic location is a geographic location included in the first recognition result or a geographic location included in the second recognition result.
In the embodiment of the application, the first recognition result and the second recognition result may be preferentially used as criteria, and when the geographic position included in the first recognition result is consistent with the geographic position included in the second recognition result, the geographic position included in the first recognition result may be determined as the actual geographic position corresponding to the mobile terminal, and the positioning accuracy may reach a city. The geographic location included in the first recognition result is consistent with the geographic location included in the second recognition result, which may mean that the country included in the first recognition result is the same as the country included in the second recognition result. That is, when the geographic locations corresponding to the two main recognition results are consistent, the geographic location included in the recognition result corresponding to the latitude and longitude information is determined as the actual geographic location corresponding to the mobile terminal.
When the geographic location included in the first recognition result is inconsistent with the geographic location included in the second recognition result, it may be understood that the country included in the first recognition result is different from the country included in the second recognition result, and the actual geographic location corresponding to the mobile terminal may be determined with reference to the third recognition result and/or the fourth recognition result.
In the embodiment of the application, the preset algorithm referring to the third recognition result and/or the fourth recognition result can be designed according to actual conditions. For example, a first distance between the geographic position included in the third recognition result and the geographic position included in the first recognition result and a second distance between the geographic position included in the second recognition result and the geographic position included in the third recognition result and/or the fourth recognition result are respectively calculated, the magnitudes of the first distance and the second distance are compared, and the corresponding recognition result with the smaller distance is determined as a final recognition result, wherein when the distance is calculated, the calculation can be performed based on a geometric center point of a range covered by the geographic position.
For example, if the distance between the geographic position in the third recognition result and the geographic position in the first recognition result is a, the distance between the geographic position in the third recognition result and the geographic position in the second recognition result is b, the distance between the geographic position in the fourth recognition result and the geographic position in the first recognition result is c, and the distance between the geographic position in the fourth recognition result and the geographic position in the second recognition result is d, then the first distance L1 is a + c, and the second distance L2 is b + d. When the L1 is greater than or equal to the L2, determining the geographic position contained in the first recognition result as the actual geographic position corresponding to the mobile terminal; and when the L1 is smaller than the L2, determining the geographic position contained in the second recognition result as the actual geographic position corresponding to the mobile terminal.

Exemplarily, the first recognition result and the second recognition result are voted by using the third recognition result and/or the fourth recognition result, wherein the voting rule is that the votes are cast to the recognition result consistent with the votes; and when the number of votes obtained by the second identification result is greater than that of the first identification result, determining the geographic position contained in the second identification result as the actual geographic position corresponding to the mobile terminal, otherwise, determining the geographic position contained in the first identification result as the actual geographic position corresponding to the mobile terminal. When voting is performed, voting can be performed according to whether the countries are consistent or not.
For example, when the third identification result and the fourth identification result are only one, the consistency between the third identification result or the fourth identification result and the first identification result and the consistency between the third identification result or the fourth identification result and the second identification result can be judged, if the third identification result or the fourth identification result is consistent with the first identification result, the ticket is cast to the first identification result, at this time, the number of tickets obtained by the first identification result is greater than that of the second identification result, and the geographic position contained in the first identification result can be determined as the actual geographic position corresponding to the mobile terminal; if the number of the votes is consistent with the second identification result, the votes are cast to the second identification result, at the moment, the number of the votes obtained by the second identification result is larger than that of the votes obtained by the first identification result, and the geographic position contained in the second identification result can be determined as the actual geographic position corresponding to the mobile terminal; if the first identification result and the second identification result are not consistent, or the third identification result or the fourth identification result is empty, the number of votes obtained for the first identification result and the second identification result is 0, the first identification result and the second identification result are equal, the geographic position contained in the first identification result can be determined as the actual geographic position corresponding to the mobile terminal, and therefore the method has the advantages that the identification result corresponding to the longitude and latitude information with high accuracy can be preferentially referred, and the accuracy of position determination is improved.
Optionally, when the third recognition result and the fourth recognition result exist at the same time, the third recognition result and the fourth recognition result are respectively voted, and the actual geographic location corresponding to the mobile terminal is determined according to the voting result.
And step 304, sending the actual geographic position to the mobile terminal.

If the country C is the same as the country A, voting to the country A, and if the country C is the same as the country B, voting to the country B; if the country D is the same as the country A, the voting is given to the country A, and if the country D is the same as the country B, the voting is given to the country B. And finally, counting the number of votes obtained by the country A and the country B, wherein if the number of votes of the country B is greater than the number of votes of the country A, the actual geographic position is the country B, and if the number of votes of the country B is less than or equal to the number of votes of the country A, the actual geographic position is the city X of the country A.
