Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The embodiment of the present disclosure provides a positioning method, fig. 1 is a flowchart illustrating an information processing method according to an exemplary embodiment, and as shown in fig. 1, the information processing method is applied to a terminal device located in a coverage area of a first base station, and includes the following steps:

in step 101, if the terminal device moves from the coverage of the first base station to the coverage of a second base station, acquiring base station information of the second base station;

in step 102, establishing a storage entry in a preset database based on the base station information of the second base station;

the preset database comprises at least one storage entry and is used for caching the position information of the terminal equipment in the coverage range of each base station.

It should be noted that the positioning method may be applied to any terminal device, where the terminal device may include a mobile terminal and a fixed terminal, where the mobile terminal may include: a smart phone, a tablet computer, or a wearable electronic device, etc. The fixed terminal may include: personal computers, servers, etc.

In the embodiment of the present disclosure, if it is detected that the terminal device moves from the coverage of the first base station to the coverage of the second base station, the base station information of the second base station where the terminal device is currently located may be obtained, and a storage entry is established in the preset database based on the base station information of the second base station.

In some embodiments, the range covered by the first base station and the range covered by the second base station do not overlap with each other. In the embodiment of the present disclosure, one storage entry may be established for each base station. In other embodiments, a plurality of storage entries may also be established for each base station, which may be specifically set according to needs and is not specifically limited herein.

Fig. 2 is a schematic diagram illustrating a coverage area of a base station according to an exemplary embodiment, and as shown in fig. 2, coverage areas of a first base station 201 and a second base station 202 are different, it should be noted that only the first base station 201 and the second base station 202 are illustrated in the present disclosure. In other alternative embodiments, the coverage areas of the first base station and the second base station may have other shapes, and the coverage area of the first base station and the coverage area of the second base station may also be spaced, as long as the first base station and the second base station are different base stations, which is not specifically limited herein. In other embodiments, the coverage area of the first base station and the coverage area of the second base station may also partially overlap, and are not specifically limited herein.

In the embodiment of the disclosure, when the terminal device moves from the coverage of the first base station to the coverage of the second base station, it indicates that the base station information corresponding to the terminal device currently changes, and the base station information is updated. At this time, the base station information of the second base station where the terminal device is currently located may be acquired, and a storage entry may be established in the preset data amount based on the base station information of the second base station.

In other embodiments, N base stations may be provided, where N is a positive integer greater than or equal to 2. The first base station may be any one of the N base stations, and the second base station may be any one of the N base stations except the first base station, and the types, positions and coverage areas of the first base station and the second base station are not specifically limited herein.

That is to say, in the process of caching the location information, if it is detected that the terminal device switches between the coverage areas of any two base stations in the N base stations, the base station information of the base station to which the terminal device currently corresponds may be obtained, and a storage entry is established in the preset database based on the base station information of the base station to which the terminal device currently corresponds. The base station to which the terminal device currently corresponds is the base station to which the terminal device corresponds after the handover.

Fig. 3 is a first schematic diagram illustrating establishment of a storage entry for a base station according to an exemplary embodiment, where in fig. 3, four base stations are illustrated, that is, N is equal to 4, where a first base station may be any one of the four base stations, and a second base station may be any one of the four base stations except for the first base station. In an implementation, corresponding storage entries may be established based on different base stations, for example, storage entry CID1 may be established for base station 301, storage entry CID2 may be established for base station 302, storage entry CID3 may be established for base station 303, and storage entry CID4 may be established for base station 304, respectively.

Therefore, the position information of the terminal equipment in the coverage area of each base station can be cached in the corresponding storage entry. For example, the location information of the terminal device within the coverage of the base station 301 may be stored to the storage entry CID 1; the location information of the terminal device within the coverage of the base station 302 may be stored to the storage entry CID 2; the location information of the terminal device within the coverage of the base station 303 may be stored to the storage entry CID 3; the location information of the terminal device within the coverage area of the base station 304 may be stored to the storage entry CID 4.

In some embodiments, the preset database may be in the form of a table, and for example, the preset database is a table, the storage entry in the preset database may be a row or a column in the table. Taking the storage entry as an example of a row in the table, in the embodiment of the present disclosure, when it is detected that the base station information is updated, a new row of storage entries may be created in the preset database, and the updated base station information is stored in the storage entry, because the current location information of the terminal device is not obtained at this time, a set of initial parameters (default parameters) may be set to be stored in a location corresponding to the location information, but the initial parameters are invalid values and cannot be used as valid locations. After the position information of the terminal device is subsequently acquired, the initial parameter may be updated based on the acquired position information of the terminal device.

In some embodiments, the base station information may include: a mobile country code (mcc), a mobile network code (mnc), a location area code (lac), a cell identity (cid), etc. of the base station. The location information may include: latitude (latitude), longitude (longitude), location accuracy (accuracy), and the like. Table 1 is a preset database illustrating no memory entries built according to an exemplary embodiment.

TABLE 1 Preset database with no entries built

As shown in table 1, a first column in a preset database (CacheLocation) indicates a sequence number (_ id), a second column indicates a mobile country code (mcc) and a mobile network code (mnc) of a base station, a third column indicates a location area code (lac) of the base station, a fourth column indicates a cell Identifier (cid), a fifth column indicates a network type (celltype) supported by the base station, a sixth column indicates a weight for characterizing the number of times each stored entry in the preset database is called, a seventh column indicates a latitude (latitude), an eighth column indicates a longitude (longitude), a ninth column indicates a location accuracy (access), a tenth column indicates a network connection status, and a tenth column indicates a Service Set Identifier (SSID) of a connected network. In other alternative embodiments, more columns may be provided as needed for storing data, which is not listed here.

Table 2 illustrates a provisioning database having a first storage entry established according to an exemplary embodiment.

Table 2 sets up a predetermined database of first stored entries

As shown in table 2, a first storage entry (i.e., a first row in the preset database in table 2) is newly created in the preset database, the base station information of the second base station may be stored in the first storage entry, and since the current location information of the terminal device has not been obtained at this time, a set of initial parameters (default parameters) may be set and stored in a location corresponding to the location information, for example, in table 2, the initial parameters are all set to "x", and the initial parameters are invalid values and cannot be used as valid locations. After the position information of the terminal device is subsequently acquired, the initial parameter may be updated based on the acquired position information of the terminal device.

In table 2, the first column of the first storage entry stores the sequence number "1", and the second to fifth columns store the base station information of the second base station, where the base station information of the second base station includes: mobile country code and mobile network code (mccmnc), location area code (lac), cell identification (cid), supported network type (celltype), where mccmnc is 460001, lac is 20985, cid is 139463372, and celltype is Long Term Evolution network technology (LTE).

In other embodiments, the corresponding initial parameter of the position information may also be set as required, for example, a latitude value with a value of [ -90,90] may be determined to be valid, and a latitude value with a value of 91 being invalid; a longitude value with a value of-180,180 may be determined to be valid, and if 181, an invalid longitude value; a position accuracy (error value) greater than 0 may be determined to be valid, and if 0 is not valid, the position accuracy.

In some embodiments, when querying the preset database, if the location information in the preset database is not updated or is invalid data, the location information is not read from the preset database.

In the embodiment of the disclosure, when it is detected that the base station information is updated, the base station information of the base station corresponding to the terminal device at present can be acquired, and a storage entry is established in the preset database based on the base station information.

In some embodiments, the establishing a storage entry in a preset database based on the base station information of the second base station includes:

inquiring the preset database based on the base station information of the second base station;

In some embodiments, querying the predetermined database based on the base station information comprises: and comparing the base station information of the second base station with the base station information (cached base station information) cached in the preset database to obtain a query result. If it is determined that the cache base station information identical to the base station information of the second base station does not exist in the preset database, it is determined that the position information corresponding to the base station information of the second base station does not exist in the preset data, and at this time, a first storage entry needs to be established in the preset database, so that the base station information of the second base station and the position information corresponding to the base station information of the second base station are stored through the first storage entry.

In other embodiments, similarity calculation may be performed on the base station information of the second base station and the cached base station information in the preset database, and when the similarity is less than or equal to the preset similarity, it may be determined that the position information corresponding to the base station information of the second base station does not exist in the preset database. In other embodiments, whether the location information corresponding to the base station information exists in the preset database may also be determined in other manners, which is not specifically limited herein.

In the embodiment of the disclosure, before the first storage entry is established, the preset database is queried based on the acquired base station information of the second base station, and when the query result represents that the position information corresponding to the base station information of the second base station does not exist in the preset database, the first storage entry is established in the preset database. In this way, the possibility of creating multiple duplicate memory entries for the same base station, resulting in data redundancy, can be reduced.

In other embodiments, when the query result indicates that the preset database has the location information corresponding to the base station information of the second base station, the indication indicates that the preset database has cached the location information corresponding to the second base station, and at this time, it is not necessary to repeatedly establish a storage entry in the preset database.

For example, if it is determined that the cached base station information identical to the base station information of the second base station exists in the preset database, it may be determined that the location information corresponding to the base station information of the second base station exists in the preset database. For another example, similarity calculation may be performed on the base station information of the second base station and the cached base station information in the preset database, and when the similarity is greater than the preset similarity, it may be determined that the position information corresponding to the base station information exists in the preset database. In this case, it is not necessary to repeatedly create a storage entry in the preset database.

In some embodiments, the method further comprises:

establishing a first mapping relation between the first position information and the base station information of the second base station;

and storing the base station information of the second base station, the first position information and the first mapping relation into the first storage item.

Since the initial parameter (default parameter) stored in the first storage entry after the first storage entry is created is an invalid value, the initial parameter cannot be used as a valid location. In the embodiment of the present disclosure, after the first storage entry is established, a first positioning request for the terminal device may be initiated, so as to obtain first location information of the terminal device based on the first positioning request, where the first location information is current location information of the terminal device.

In some embodiments, the first location information of the terminal device may be obtained by network positioning. For example, the first location request may be sent to a base station to obtain first location information. In other embodiments, the first position information may also be obtained by satellite positioning, and the way of obtaining the first position information is not listed here.

After the first location information is obtained, a first mapping relationship between the first location information and the base station information of the second base station may be established, and the base station information of the second base station, the first location information, and the first mapping relationship may be stored in the first storage entry. Table 3 is a preset database of updated first stored entries, according to an exemplary embodiment.

TABLE 3 Preset database of updated first memory entries

As shown in table 2, a first column of a first storage entry in a preset database (CacheLocation) stores a sequence number of "1", and second to fifth columns store base station information of a second base station, where the base station information of the second base station includes: a mobile country code and mobile network code (mccmnc), a location area code (lac), a cell identifier (cid), and a supported network type (celltype), where mccmnc is 460001, lac is 20985, cid is 139463372, celltype is Long Term Evolution (LTE), and the sixth column stores a weight of "1" indicating that the first storage entry is called once.

The seventh column to the ninth column store first position information including: latitude (latitude), longitude (longtude), and location accuracy (accuracy), wherein the latitude is "31.983417", the longitude is "118.732929", and the accuracy is "40.0". The tenth column indicates that the network connection status is "0", i.e., no connection to the predetermined network is made under the base station, and the eleventh column is empty.

In the embodiment of the disclosure, after the first location information of the terminal device is subsequently acquired, the initial parameter in the first storage entry may be updated based on the acquired first location information of the terminal device, and the base station information of the second base station, the first location information, and the first mapping relationship are stored in the first storage entry.

In some embodiments, the querying the preset database based on the base station information of the second base station includes:

and under the condition that the base station information of the second base station is within a preset range, inquiring the preset database based on the base station information.

Here, the preset range may be set as needed, for example, the preset range may be determined according to the content included in the base station information of the second base station, so as to ensure that the base station information conforms to the communication specification and ensure the validity of the base station information.

Taking the base station information as an example of a mobile country code, if the mobile country code is greater than 0, it indicates that the mobile country code is valid, and if the mobile country code is less than or equal to 0, it indicates that the mobile country code is invalid. Taking the base station information as a mobile network code as an example, if the mobile network code is less than or equal to 0, it indicates that the mobile network code is invalid. Taking the base station information as a location area code as an example, if the location area code is not equal to-1 and is smaller than the area code upper limit, it indicates that the location area code is valid; if the location area code is equal to-1 or greater than or equal to the area code upper limit, it indicates that the location area code is invalid. Taking the base station information as the cell identifier as an example, if the cell identifier is a positive integer, the cell identifier is valid; if the cell identification is not a positive integer, the cell identification is invalid.

The base station information at the second base station simultaneously includes: when the mobile country code, the mobile network code, the location area code, and the cell id are all valid, the base station information of the second base station is also valid.

In the embodiment of the disclosure, before querying the preset database based on the base station information of the second base station, the validity of the base station information of the second base station is determined, and under the condition that the base station information of the second base station is valid, the preset database is queried based on the base station information of the second base station, so that the possibility of invalid data processing can be reduced, and the efficiency of data processing can be improved.

In some other embodiments, the establishing a storage entry in a preset database based on the base station information of the second base station includes: and under the condition that the terminal equipment is not connected to a preset network, establishing a storage item in the preset database based on the base station information of the second base station.

Here, in a case where the terminal device is not connected to the preset network, a storage entry may be established in the preset database directly based on the base station information of the second base station. In other embodiments, in the case where the terminal device is connected to the preset network, the storage entry may be established based on the base station information of the second base station and the network information of the preset network.

In some embodiments, the establishing a storage entry in a preset database based on the base station information of the second base station includes:

acquiring network information of a preset network under the condition that the terminal equipment is connected to the preset network;

and establishing a second storage item in the preset database based on the base station information of the second base station and the network information of the preset network.

Here, the preset network may include: Wi-Fi networks, cellular networks, etc. The network information of the preset network may include: network connection status (hashfi), network identification (e.g., SSID of network), etc. Taking the preset network as a Wi-Fi network as an example, in the embodiment of the present disclosure, when the terminal device is connected to the Wi-Fi network, the network connection state and the SSID of the Wi-Fi network may be acquired.

Fig. 4 is a second schematic diagram illustrating that a storage entry is established for a base station according to an exemplary embodiment, where in fig. 4, four base stations are illustrated, that is, N is equal to 4, where a first base station may be any one of the four base stations, and a second base station may be any one of the four base stations except for the first base station. In an implementation, corresponding storage entries may be established based on different base stations, for example, storage entry CID1 may be established for base station 301, storage entry CID2 may be established for base station 302, storage entry CID3 may be established for base station 303, and storage entry CID4 may be established for base station 304, respectively.

In the implementation process, if the terminal device is located within the coverage of the base station 303 and the terminal device is connected to the preset network wifi ssid1 and the preset network wifi ssid2, a second storage entry may be established in the preset database based on the base station information of the base station 303, the network information of the preset network wifi ssid1 and the network information of the preset network wifi ssid 2.

In some embodiments, the preset database may be in the form of a table, and for example, the preset database is a table, the storage entry in the preset database may be a row or a column in the table. Taking an example that the storage entry is a row in the table, in the embodiment of the present disclosure, when it is detected that the network information is updated, a row of storage entries may be newly created in the preset database, and the base station information of the second base station and the network information of the preset network are stored in the storage entry, because the current location information of the terminal device is not obtained yet at this time, a set of initial parameters (default parameters) may be set to be stored in a location corresponding to the location information, but the initial parameters are invalid values and cannot be used as valid locations. After the position information of the terminal device is subsequently acquired, the initial parameter may be updated based on the acquired position information of the terminal device.

Table 4 is a preset database that establishes a second storage entry according to an exemplary embodiment.

Table 4 establishes a predetermined database of second memory entries

As shown in table 4, a second storage entry (i.e., a second row in the preset database in table 4) is newly created in the preset database, the base station information of the second base station and the network information of the preset network may be stored in the second storage entry, and since the current location information of the terminal device is not obtained at this time, a set of initial parameters (default parameters) may be set to be stored in a location corresponding to the location information, for example, in table 4, the initial parameters are all set to "0", and the initial parameters are invalid values and cannot be used as valid locations. After the position information of the terminal device is subsequently acquired, the initial parameter may be updated based on the acquired position information of the terminal device.

In table 4, the first column of the first storage entry stores the sequence number "2", and the second to fifth columns store the base station information of the second base station, which includes: mobile country code and mobile network code (mccmnc), location area code (lac), cell identification (cid), supported network type (celltype), where mccmnc is 460001, lac is 20985, cid is 139463372, and celltype is Long Term Evolution network technology (LTE). The seventh column to the ninth column store initial parameters of the position information. The tenth column and the eleventh column store network information of the preset network, that is, the network status information is "1", which indicates that the terminal device is connected to the preset network, and the network identifier is "llp-5 g".

In the embodiment of the disclosure, when it is detected that the base station information and the network information are updated, the base station information of the base station corresponding to the terminal device at present and the network information of the preset network can be acquired, and a storage entry is established in the preset database based on the base station information and the network information.

Therefore, on the one hand, when the terminal equipment needs to be positioned again, the cached position information can be directly acquired from the preset database based on the base station information and the network information, and compared with real-time network positioning, the terminal equipment only needs to read the database, so that the power consumption of the terminal equipment can be reduced, and the cruising ability of the terminal equipment is further improved. On the other hand, by storing the cached location information in the form of a database in the storage medium of the terminal device, persistent storage of the location information can be realized, and the availability of the location information stored in the database can be ensured even if the terminal device is restarted.

In some embodiments, the establishing a second storage entry in the preset database based on the base station information of the second base station and the network information of the preset network includes:

inquiring the preset database based on the base station information of the second base station and the network information of the preset network;

In some embodiments, querying the preset database based on the base station information of the second base station and the network information of the preset network includes: and comparing the base station information of the second base station with the base station information (cache base station information) cached in the preset database, and simultaneously comparing the network information of the preset network with the network information (cache network information) cached in the preset database to obtain a query result.

If it is determined that the cache base station information identical to the base station information of the second base station does not exist in the preset database or the cache network information identical to the network information of the preset network does not exist in the preset database, it is determined that the position information corresponding to the base station information of the second base station and the network information of the preset network does not exist in the preset data, and at this time, a second storage entry needs to be established in the preset database so as to store the position information corresponding to the base station information of the second base station and the network information of the preset network through the second storage entry.

In the embodiment of the disclosure, before the second storage entry is established, a preset database is queried based on the obtained base station information of the second base station and the network information of the preset network, and when the query result represents that no position information corresponding to the base station information of the second base station and the network information of the preset network exists in the preset database, the second storage entry is established in the preset database. In this way, the possibility of creating multiple duplicate memory entries for the same base station, resulting in data redundancy, can be reduced.

In other embodiments, when the query result indicates that the location information corresponding to the base station information of the second base station and the network information of the preset network simultaneously exists in the preset database, the location information corresponding to the second base station and the preset network is already cached in the preset database, and at this time, it is not necessary to repeatedly establish a storage entry in the preset database.

For example, if it is determined that the cached base station information identical to the base station information of the second base station exists in the preset database and the cached network information identical to the network information of the preset network exists, it may be determined that the location information corresponding to the base station information of the second base station and the network information of the preset network exists in the preset database, and at this time, it is not necessary to repeatedly establish a storage entry in the preset database.

In some embodiments, the method further comprises:

establishing a second mapping relation among the base station information of the second base station, the network information of the preset network and the second position information;

Since the initial parameter (default parameter) stored in the second storage entry after the second storage entry is created is an invalid value, the initial parameter cannot be used as a valid location. In the embodiment of the present disclosure, after the second storage entry is established, a second positioning request for the terminal device may be initiated, so as to obtain second location information of the terminal device based on the second positioning request, where the second location information is current location information of the terminal device.

In some embodiments, the second location information of the terminal device may be obtained by network positioning. For example, the second positioning request may be sent to the base station to obtain the second location information. In other embodiments, the second position information may also be obtained by satellite positioning, and the way of obtaining the second position information is not listed here.

After the second location information is obtained, a second mapping relationship among the base station information of the second base station, the network information of the preset network, and the second location information may be established, and the base station information of the second base station, the network information of the preset network, the second location information, and the second mapping relationship may be stored in a second storage entry. Table 5 is a preset database of updated second storage entries, shown according to an exemplary embodiment.

Table 5 updated preset database of second storage entries

As shown in table 5, the first column of the second storage entry in the preset database (CacheLocation) stores the sequence number "2", and the second column to the fifth column store the base station information of the second base station, where the base station information of the second base station includes: a mobile country code and mobile network code (mccmnc), a location area code (lac), a cell identifier (cid), and a supported network type (celltype), where mccmnc is 460001, lac is 20985, cid is 139463372, celltype is Long Term Evolution (LTE), and the sixth column stores a weight of "1" indicating that the first storage entry is called once.

The seventh column to the ninth column store first position information including: latitude (latitude), longitude (longtude), and location accuracy (accuracy), wherein latitude is "91.0", longitude is "181.0", and accuracy is "0.0". The tenth column indicates that the network connection status is "1", i.e., the base station is connected to the preset network, and the eleventh column is the network identifier "llp-5 g".

In the embodiment of the disclosure, after the second location information of the terminal device is subsequently acquired, the initial parameter in the second storage entry may be updated based on the acquired second location information of the terminal device, and the base station information of the second base station, the network information of the preset network, the second location information, and the second mapping relationship are stored in the second storage entry.

In some embodiments, the method further comprises:

and updating the position information in the preset database based on the application position information acquired by the application program installed on the terminal equipment.

In the embodiment of the disclosure, a listener may be registered in the terminal device, and when it is monitored that an application program on the terminal device obtains application location information of the terminal device, location information in a preset database on the terminal device may be updated based on the application location information.

For example, after detecting the application location information of the terminal device, the current base station information of the base station corresponding to the terminal device at present may be obtained, and the current base station information may be compared with the cache base station information in the preset database, and in a case that there is cache base station information identical to the current base station information in the preset database, the location information corresponding to the cache base station information identical to the current base station information may be updated based on the application location information. Therefore, the cached position information in the preset database can be more real-time and accurate by utilizing the positioning function of the application program installed on the terminal equipment on the basis of not carrying out additional positioning requests.

In some embodiments, the method further comprises:

and returning the position information corresponding to the base station information carried in the third positioning request to the target application program.

In this disclosure, in a process of using a preset database, if it is detected that a target application program initiates a third positioning request, base station information carried in the third positioning request may be compared with cache base station information in the preset database, and in a case that the preset database has cache base station information that is the same as the base station information carried in the third positioning request, location information corresponding to the cache base station information that is the same as the base station information carried in the third positioning request may be determined as location information corresponding to the base station information carried in the third positioning request, and the location information corresponding to the base station information carried in the third positioning request is returned to the target application program. Therefore, the terminal equipment can be positioned by reading the cached position information from the preset database, and the position information is returned to the target application program, compared with a mode of initiating network positioning in real time in the related art, the power consumption of the terminal equipment can be reduced, the positioning step is mainly executed locally in the terminal equipment, and the positioning speed can be increased.

In some embodiments, the method further comprises:

In the embodiment of the present disclosure, in the process of using the preset database, if the terminal device is connected to the preset network, based on the base station information carried in the third positioning request and the network information carried in the third positioning request, the location information corresponding to both the base station information carried in the third positioning request and the network information carried in the third positioning request may be acquired from the preset database.

For example, the base station information carried in the third positioning request and the network information carried in the third positioning request may be compared with the cache base station information and the cache network information in the preset database, and in the case that the preset database has the cache base station information that is the same as the base station information carried in the third positioning request and has the cache network information that is the same as the network information carried in the third positioning request, the location information simultaneously corresponding to the cache base station information and the cache network information may be determined as the location information simultaneously corresponding to the base station information carried in the third positioning request and the network information carried in the third positioning request, and the location information may be returned to the target application program. Therefore, the terminal equipment can be positioned by reading the cached position information from the preset database, and the position information is returned to the target application program, compared with a mode of initiating network positioning in real time in the related art, the power consumption of the terminal equipment can be reduced, the positioning step is mainly executed locally in the terminal equipment, and the positioning speed can be increased.
