Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a diagram illustrating an application scenario of a positioning method according to an exemplary embodiment. As shown in fig. 1, the positioning method provided in this embodiment is applied to a positioning system, where the positioning system includes a terminal device, a location service platform, and a cloud data platform, where the location service platform is in communication connection with the terminal device and the cloud data platform, respectively, and the cloud data platform is in communication connection with base stations in each cell. The method comprises the steps that various application programs are arranged on terminal equipment, when a positioning request is initiated by the application programs, the terminal equipment sends identity identification information and first historical sequence information corresponding to the terminal equipment to a position service platform, so that the position service platform obtains second historical sequence information corresponding to the terminal equipment from a cloud data platform according to the identity identification information, the legality of the first historical sequence information is verified according to the second historical sequence information, and only when the two data are completely consistent, the current cell identification code is analyzed, so that the current position data of the current terminal equipment is obtained, positioning cheating behaviors are avoided, and the positioning operation safety and reliability of the application programs are improved.
Fig. 2 is a signaling interaction diagram illustrating a positioning method according to an example embodiment. As shown in fig. 2, the positioning method provided in this embodiment includes:
s101, a positioning request initiated by an application program is obtained.
Specifically, when an application program on the terminal device, such as a ticketing application, a financial application, or a payment application, needs to perform user location authentication, the terminal device obtains a location request initiated by the application program. In a possible implementation manner, the positioning request may be to display a request window that needs to acquire the current location of the user on a display interface of the terminal device, for example, "whether to allow the XXX application to acquire the current location information of the mobile phone" in the window, the user may select to continue the user location authentication, or may select to cancel the option, thereby terminating the authentication.
When the user selects to perform the position authentication, the terminal device acquires the first historical sequence information stored in the memory of the terminal device and the identity identification information corresponding to the terminal device, and sends the acquired first historical sequence information and the identity identification information corresponding to the terminal device to the position service platform.
It should be noted that the identification information may be an electronic identification code in a SIM card built in the terminal device, or a serial number of the terminal device, and if the identification information is the serial number of the terminal device, the serial number of the terminal device needs to be registered in the cloud data platform before use.
The first history sequence information may specifically include a cell identifier history sequence stored by the terminal device. Fig. 3 is a schematic structural diagram of a possible storage form of the first history sequence information in the embodiment shown in fig. 2, and as shown in fig. 3, a plurality of cell identifiers are stored in the first history sequence information, where the cell identifiers are stored in a sorted manner according to a chronological order, that is, the earlier stored cell identifier is stored at the bottom of the data structure. For example, at 2018.09.016:00 am, the terminal device is registered with the base station corresponding to the a cell, and at the same time, the "a cell identifier" is stored in the first history sequence information of the terminal device at that time; at 2018.09.0113:00pm, the ue registers with the bs corresponding to the B cell, and at the same time, the "B cell id" is stored in the first history sequence information of the ue at that time; then, at the current time 2018.09.129:00am, the relevant application on the terminal device initiates a positioning request, and the terminal device registers with the base station corresponding to the X cell, and at this time, the "X cell id" is stored in the first history sequence information of the terminal device.
And S102, sending the identity identification information corresponding to the terminal equipment and the first historical sequence information.
Specifically, after acquiring first history sequence information stored in a memory of the terminal device and identification information corresponding to the terminal device, the terminal device sends the acquired first history sequence information and the identification information corresponding to the terminal device to the location service platform.
And S103, sending the identity identification information corresponding to the terminal equipment.
After receiving first historical sequence information sent by terminal equipment and identity identification information corresponding to the terminal equipment, the position service platform firstly sends the identity identification information corresponding to the terminal equipment to the cloud data platform, and then second historical sequence information corresponding to the identity identification information is sent to the cloud data platform. If the identity identification information is an electronic identity identification code in an SIM card built in the terminal equipment, a cell base station specifically registered by the SIM card and specific registration time can be searched in a cloud data platform according to the electronic identity identification code in the SIM card.
And S104, acquiring second historical sequence information corresponding to the identification information.
It should be noted that the cloud data platform may be a data management platform of an operator, for example, a data platform of a connected O domain, where the cloud data platform updates and stores uplink and downlink data of base stations in each cell in real time and periodically, and for registration of a cell, switching data is synchronized in real time.
For example, at 2018.09.016:00 am, the terminal device is registered in the base station corresponding to the cell a, and at this time, the base station corresponding to the cell a reports the identification information, the cell a identification code, and the specific time of occurrence of the registration behavior corresponding to the terminal device to the cloud data platform; at 2018.09.0113:00pm, the terminal device is registered in the base station corresponding to the cell B, and at this moment, the base station corresponding to the cell B reports the identity identification information, the cell B identification code and the specific time of occurrence of the registration behavior corresponding to the terminal device to the cloud data platform; and then, when a positioning request is initiated by a relevant application program on the terminal device at the current time 2018.09.129:00am, the terminal device is registered in a base station corresponding to the X cell, and the base station corresponding to the X cell reports the identity identification information, the X cell identification code and the specific time of occurrence of the registration behavior corresponding to the terminal device to the cloud data platform at the time.
When the terminal equipment is registered every time, the base station in the cell records the identity identification information corresponding to the terminal equipment, and the base station in the cell reports the identity identification information corresponding to the terminal equipment to the cloud data platform. Therefore, after the cloud data platform receives the identification information, the corresponding second historical sequence information can be acquired in the database according to the identification information.
And S105, sending second history sequence information.
After the cloud data platform acquires the second historical sequence information according to the identity identification information corresponding to the terminal device, in order to verify the first historical sequence information on the location service platform, the acquired second historical sequence information can be fed back to the location service platform.
And S106, verifying the legality of the first historical sequence information according to the second historical sequence information.
Specifically, the location services platform may determine the validity of the first historical sequence information by comparing the first historical sequence information with the second historical sequence information.
FIG. 4 is a schematic diagram of one possible verification comparison of the first historical sequence information and the second historical sequence information shown in FIG. 3. As shown in fig. 4, if the data in the first history sequence information and the data in the second history sequence information are completely matched and consistent, the location service platform may determine that the first history sequence information is legal.
And FIG. 5 is a schematic diagram of another possible verification comparison of the first historical sequence information and the second historical sequence information shown in FIG. 3. As shown in fig. 5, the data in the first history sequence information and the second history sequence information do not match completely, for example, the D cell id of the first history sequence information does not match the F cell id.
In order to improve the verification efficiency, the first historical sequence information can be set to be a data structure comprising N cell identification codes, wherein N is an integer greater than 1, and the terminal device sends the identity identification information and the first historical sequence information to the location service platform according to a positioning request initiated by an application program, and simultaneously sends the threshold value N to the location service platform, so that the location service platform further sends the threshold value N to the cloud data platform, and the cloud data platform obtains second historical sequence information of the same data structure.
The N cell identification codes are arranged according to the storage time corresponding to the terminal equipment, and the later the storage time is, the earlier the corresponding cell identification code is, namely the cell identification code is stored by adopting a first-in first-out chain data structure for maintenance. For example, when N is 2, the terminal device registers in the base station corresponding to the a cell at 2018.09.016:00 am, and at the same time, the "a cell identification code" is stored in the first history sequence information of the terminal device at that time; at 2018.09.0113:00pm, the terminal device registers with the base station corresponding to the B cell, and at that time, the "B cell id" is stored in the first history sequence information of the terminal device, and it is seen that the "a cell id" and the "B cell id" are stored in the first history sequence information. However, if a positioning request is initiated by the relevant application on the terminal device at the current time 2018.09.129:00am, the terminal device registers with the base station corresponding to the X cell, and at this time, the "X cell id" is stored in the first history sequence information of the terminal device, and the "a cell id" is deleted from the first history sequence information.
In addition, N can be set to different values according to different required checking accuracy of the application program, for the application program with higher requirement of checking accuracy, N can be set to a larger value,
and S107, if the first historical sequence information is legal, analyzing the current position data according to the latest added cell identification code in the first historical sequence information.
Specifically, if the position service platform verifies that the verification result of the first historical sequence information is that the first historical sequence information is legal according to the second historical sequence information, the current position data is analyzed according to the newly added cell identification code in the first historical sequence information. For example, the current location data of the terminal device is obtained by performing analysis according to the "X cell identifier" corresponding to the terminal device at the current time 2018.09.129:00 am.
And S108, sending the current position data to the terminal equipment.
After the location service platform resolves the current location data according to the newly added cell identification code in the first historical sequence information, the location service platform sends the current location data to the terminal device, so that the application program initiating the positioning request obtains the current location data of the terminal device.
In this embodiment, by comparing whether a difference exists between first historical sequence information stored in the terminal device and second historical sequence information corresponding to the terminal device acquired from the cloud data platform, the current cell identification code is analyzed only when the two pieces of data are completely consistent, so that the current position data of the current terminal device is acquired, the occurrence of positioning cheating is avoided, and the positioning operation safety and reliability of the application program are improved.
On the basis of the above embodiment, in order to further increase the reliability of the positioning, the storage registration time may be further increased in the first history sequence information on the basis of the storage format structure shown in fig. 3. Fig. 6 is a schematic structural diagram of another possible storage form of the first history sequence information in the embodiment shown in fig. 2. As shown in fig. 6, as shown in fig. 3, several cell identifiers and the time when each cell identifier is registered in the base station and stored in the terminal device are stored in the first history sequence information, wherein the cell identifiers are stored in a chronological order, that is, the earlier stored cell identifiers are stored at the bottom of the data structure. For example, when the "a time" is 2018.09.016:00 am, the terminal device is registered with the base station corresponding to the a cell, and at this time, the "a cell identifier" and the "a time" are stored in the first history sequence information of the terminal device; the terminal device registers in the base station corresponding to the B cell at 2018.09.0113:00pm time "B", and at the same time, the first history sequence information of the terminal device stores the "B cell identification code" and the "B time" at the time; then, when the current time "X time" is 2018.09.129:00am, a positioning request is initiated by a relevant application program on the terminal device, the terminal device registers at a base station corresponding to the X cell, and at the same time, the "X cell identification code" and the "X time" are stored in the first historical sequence information of the terminal device at the time.
Correspondingly, the registration data in the base station may further include registration time of the terminal device in each base station, for example, when "a time" is 2018.09.016: 00am, the terminal device is registered in the base station corresponding to the cell a, and at this time, the base station corresponding to the cell a reports the identification information corresponding to the terminal device, the cell a identification code, and the specific time "a time" at which the registration behavior occurs to the cloud data platform; when the time "B" is 2018.09.0113:00pm, the terminal device is registered in the base station corresponding to the cell B, and at the moment, the base station corresponding to the cell B reports the identity identification information, the cell B identification code and the specific time "B" of the registration behavior corresponding to the terminal device to the cloud data platform; and then, when the current time 'X time' is 2018.09.129:00am, a positioning request is initiated by a related application program on the terminal device, the terminal device is registered in a base station corresponding to the X cell, and at the time, the base station corresponding to the X cell reports the identity identification information, the X cell identification code and the specific time 'X time' of the registration behavior corresponding to the terminal device to the cloud data platform.

As shown in fig. 7, if the data in the first history sequence information and the data in the second history sequence information are completely matched and consistent, the location service platform may determine that the first history sequence information is legal. The location service platform resolves the current location data according to the latest cell identification code added in the first historical sequence information, namely the 'X cell identification code'.
And FIG. 8 is a schematic diagram of another possible verification comparison of the first historical sequence information and the second historical sequence information shown in FIG. 6.
