Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Aiming at the problem that in the existing scheme, positioning errors are caused because WIFI data or mobile communication network data uploaded to a positioning platform are not data of a real position, the embodiment of the application acquires two pieces of position information corresponding to two positioning modes from position data uploaded by a terminal; and determining the position of the terminal according to the distance between the two pieces of position information and the network type information when the terminal uploads the position data.
The two positioning modes of the embodiment of the application can be both indoor positioning modes, or can be both outdoor positioning modes, or can be both indoor positioning modes and outdoor positioning modes. Optionally, the two positioning manners may include: the positioning method comprises two modes of a mobile communication network positioning mode, a WIFI positioning mode, a Bluetooth positioning mode and a GPS positioning mode. It is understood that the embodiment of the present application is not limited to the specific two positioning manners.
In this embodiment, the distance between the two pieces of location information may be used as a basis for determining whether location data corresponding to one of the two positioning manners is not updated; optionally, when the absolute value of the distance between the two pieces of location information exceeds the distance threshold, it is determined that the location data corresponding to one of the two positioning manners is not updated because the proximity between the two pieces of location information is low or the deviation degree is high.
In the embodiment of the present application, when it is determined that the location data corresponding to one of the two positioning manners is not updated, the location of the terminal may be determined according to the network type information used by the terminal to upload the location data; the network type information used by the terminal to upload the location data and the location data corresponding to the two positioning modes may have a certain association, so the network type information may be used as a basis for determining the location of the terminal.
To sum up, in the method for processing location data according to the embodiment of the present application, a distance between two pieces of location information may be used as a basis for determining whether location data corresponding to one of the two positioning manners is not updated, and network type information is also used when the location data corresponding to the two positioning manners is uploaded.
In an application example of the application, a user is on a business trip from beijing to tokyo in japan, and if the user just starts the airplane to get off, the user does not scan WIFI in time, and the terminal uploads data of the WIFI connected to the user before the user gets on the airplane to the positioning platform through the mobile communication network, the embodiment of the application can acquire the WIFI data and the mobile communication network data uploaded by the terminal at the same time, and judging whether the absolute value of the distance between the second position information and the first position information corresponding to the WIFI data and the mobile communication network data exceeds a distance threshold value, if so, one of the WIFI data and the mobile communication network data is considered to exist and not updated, and further according to the network type information (mobile communication network type information) adopted by the terminal for uploading the WIFI data and the mobile communication network data, the WIFI data is determined to be the non-updated data, therefore, the first position information can be selected from the first position information and the second position information as the position of the terminal; the second location information corresponding to the non-updated WIFI data can be discarded, so that the problems of location errors and LBS service errors caused by the location errors can be effectively avoided.
The embodiment of the present application may be applied to an application environment of a positioning system, and referring to fig. 1, an exemplary structural schematic diagram of a positioning system of the present application is shown, which may specifically include: a terminal 101 and a positioning platform 102.
The terminal 101 may be configured to obtain the location data, and upload the obtained location data to the positioning platform 102 through a network. Optionally, the terminal 101 may periodically and actively upload the acquired location data to the positioning platform 102, or may upload the acquired location data according to an instruction of the positioning platform.
Optionally, the terminal 101 may obtain, for the current position, position data corresponding to at least two positioning manners, and upload the position data corresponding to the at least two positioning manners at the same time. Optionally, the position data corresponding to the at least two positioning manners may include: mobile communication network data and WIFI data. Optionally, the mobile communication network data may specifically include: the parameters of the base station of the mobile communication network, or the WIFI data may specifically include: WIFI parameters, for example, the WIFI parameters may include: SSID (Service Set Identifier), a Media Access Control (MAC) address of WIFI, and/or a WIFI signal strength value, and the like.
Specifically, as a specific embodiment of the present application, the terminal may include but is not limited to: smart phones, tablet computers, electronic book readers, MP3 (Moving Picture Experts Group Audio Layer III) players, MP4 (Moving Picture Experts Group Audio Layer IV) players, laptop portable computers, car-mounted computers, desktop computers, set-top boxes, smart televisions, wearable devices, and the like.
In an optional embodiment of the present application, before the terminal 101 uploads the location data to the positioning platform 102, the terminal 101 may further obtain the network type information currently connected to the terminal 101, and simultaneously uploads the location data and the network type information currently connected to the positioning platform 102.
Optionally, the network types may include: a WIFI type, a mobile communication network type, a bluetooth network type, etc. The WIFI type, that is, the terminal 101 currently establishes network connection with the wireless access point, and at this time, the terminal 101 acquires network data through the wireless network. A precondition for the mobile communication network type, i.e. a 2G (second generation mobile phone communication specification) or 3G (third generation mobile phone communication specification) or 4G (fourth generation mobile phone communication specification) network, to be able to connect and use the mobile communication network by the terminal 101 is that the user of the terminal 101 opens mobile data traffic for the terminal 101. Bluetooth is a short-distance low-power-consumption wireless transmission technology, after a proper Bluetooth local area network access point is installed indoors, a network is configured into a basic network connection mode based on multiple users, the Bluetooth local area network access point is guaranteed to be a main device of the micro network all the time, and therefore position information of the users can be obtained by detecting signal intensity.
Optionally, the terminal 101 obtains the currently connected network type information by detecting a switch state of a network connection function (specifically, including a WIFI connection function, a mobile communication network connection function, and a bluetooth network connection function) of the terminal. For example, if the WIFI connection function is in an on state, and a certain WIFI network connected to the terminal 101 is available, and the mobile communication network connection function is in an off state, the network type information currently connected is a WIFI type. For another example, if the WIFI connection function is in an open state, and a certain WIFI network connected to the terminal 101 is available, and the mobile communication network connection function is in an open state, the network type information currently connected is a WIFI type under the condition that the terminal 101 preferentially uses the wireless network. If the WIFI connection function is in a closed state and the mobile communication network connection function is in an open state, the currently connected network type information is the mobile communication type. Or, if the bluetooth network connection function is in an on state, and a certain bluetooth network connected to the terminal 101 is available, and the mobile communication network connection function is in an off state, the currently connected network type information is a bluetooth network type. It can be understood that the embodiment of the present application does not impose a limitation on the specific manner of acquiring the network type information of the current connection.
The positioning platform 102 may be configured to obtain location data uploaded by the terminal 101 and network type information used by the terminal 101 to upload the location data; wherein the location data may include: the position data corresponding to the at least two positioning manners, for example, the position data corresponding to the at least two positioning manners may include: mobile communication network data, WIFI data, GPS data, bluetooth network data, and the like.
In practical applications, the positioning platform 102 may be configured as a server, and the manner of obtaining the network type information used by the terminal 101 to upload the location data may include:
acquiring mode 1, and taking currently connected network type information uploaded simultaneously with the position data by the terminal as the network type information when the terminal uploads the two position information; or
And in the acquisition mode 2, network type information when the terminal uploads the position data is obtained according to the information of the data packet corresponding to the position data uploaded by the terminal.
Alternatively, it may be determined by which network type the packet is transmitted according to an IP (Internet Protocol) address in the header of the packet. For various network types included in the mobile communication network, the corresponding IP address is usually an IP address within a preset IP range allocated by the gateway, so that it can be determined whether the IP address of the data packet is within the preset IP range, and if so, the network type corresponding to the data packet is considered as the mobile communication network type. For example, for an LTE (Long Term Evolution) Network system, before sending a Data Packet, a terminal performs authentication with an LTE core Network through a standard LTE Attach (Attach) procedure, registers in the LTE core Network, and after the authentication is passed, the terminal obtains an IP address allocated to an LTE link by an LTE PDN-GW (Packet Data Network Gateway).
It can be understood that the above-mentioned manner of identifying the WIFI type and the mobile communication network type according to the IP address in the packet header of the data packet is only an optional embodiment, and actually, a person skilled in the art may adopt other identification manners according to different characteristics of the WIFI type, the mobile communication network type, and the bluetooth network type, and the embodiment of the present application does not limit the specific identification manner.
In this embodiment, the positioning platform 102 may obtain two pieces of position information corresponding to the two positioning manners from the position data uploaded by the terminal. Optionally, the positioning platform 102 may match the position data corresponding to the two positioning manners with the standard feature fingerprint in the building fingerprint library, obtain the indoor position coordinate of the building corresponding to the successfully matched standard feature fingerprint, and use the indoor position coordinate of the building as the two position information corresponding to the two positioning manners, respectively.
In the embodiment of the application, the building fingerprint database can be used for recording the corresponding relation between the indoor position coordinates of buildings and the standard characteristic fingerprints. Alternatively, the standard feature fingerprint may be a vector uniquely composed of the relevant parameters of the position data acquired at the corresponding position. For WIFI data, the location data related parameters may include: l WiFi parameters with higher signal intensity at the indoor position coordinate; for mobile communication network data, the location data related parameters may include: m current serving base station parameters in the mobile communication network and N neighboring base station parameters corresponding to each current serving base station, wherein L, M, N are positive integers respectively. That is, in the embodiment of the present application, location data related parameters may be collected at each location in the building in advance, where the location data related parameters include L WiFi parameters with a large signal intensity at the indoor location coordinate, or M current service base station parameters in the mobile communication network and N neighboring base station parameters corresponding to each current service base station, and each set of location data related parameters respectively form a vector, that is, a standard feature fingerprint, and a corresponding relationship between the indoor location coordinate of the building and the standard feature fingerprint is established in the building fingerprint database.
It can be understood that the above-mentioned manner of matching the mobile communication network data and the WIFI data with the standard feature fingerprint in the building fingerprint library is only an optional embodiment of the two obtaining manners corresponding to the two location information respectively corresponding to the two positioning manners, and actually, a skilled person in the art may adopt, according to the actual application requirements, other obtaining manners corresponding to the two location information respectively corresponding to the two positioning manners, for example, the principle of the bluetooth positioning manner may be: a Bluetooth beacon (beacon) base station continuously sends beacon broadcast messages (the messages contain transmitting power), and after receiving the beacon broadcast messages, a terminal carrying a Bluetooth 4.0 module measures the receiving power, brings the receiving power into a function of the relation between power attenuation and distance, and measures and calculates the distance from the beacon base station; and determining the position of the terminal by using the distances from the plurality of beacon base stations. The embodiment of the present application does not limit the specific obtaining manner corresponding to the two position information respectively corresponding to the two positioning manners.
After acquiring two pieces of location information corresponding to two types of location manners from the location data uploaded by the terminal, the location platform 102 may determine the location of the terminal according to the distance between the two pieces of location information and the network type information when the location data is uploaded by the terminal.
Taking two positioning modes as a mobile communication network positioning mode and a WIFI positioning mode as examples, assuming that the position information respectively corresponding to the mobile communication network positioning mode and the WIFI positioning mode is the first position information and the second position information, the absolute value of the distance between the first position information and the second position information may be determined, and whether the absolute value of the distance exceeds the distance threshold is determined. If the absolute value of the distance exceeds the distance threshold, it indicates that the proximity of the first location and the second location is low and the degree of deviation is high, and therefore, it can be considered that one of the mobile communication network data and the WIFI data is not updated, that is, one of the first location information and the second location information is a true and reliable location, and one of the first location information and the second location information can be selected as the location of the terminal.
It should be noted that, if the absolute value of the distance does not exceed the distance threshold, it indicates that the proximity of the first location information and the second location information is higher, and the deviation degree is lower, so it can be considered that neither of the mobile communication network data and the WIFI data is not updated, and both the mobile communication network data and the WIFI data are true and reliable. Because the terminal is positioned by adopting the position data related parameters which can comprise WiFi parameters and base station parameters in the mobile communication network, the indoor positioning accuracy can be improved; in addition, the existing communication equipment and resources can be directly utilized, special investment is not needed, and the infrastructure and operation cost of indoor accurate positioning is greatly reduced.
Referring to fig. 2, a flowchart illustrating steps of a method for processing location data according to an embodiment of the present application is shown, where the method specifically includes the following steps:
the embodiment of the application can be applied to devices with positioning functions, such as a positioning platform and the like, and is used for avoiding the problems of positioning errors and LBS service errors caused by the positioning errors.
In practical application, the position data periodically and actively uploaded by the terminal can be received, or an instruction can be sent to the terminal, and the position data returned by the terminal according to the instruction can be received.
Further, the embodiment of the application may obtain the network type information used by the terminal to upload the location data in the following manner: taking the currently connected network type information uploaded by the terminal simultaneously with the position data as the network type information when the terminal uploads the two position information; or obtaining the network type information when the terminal uploads the position data according to the information of the data packet corresponding to the position data uploaded by the terminal. It can be understood that, in the embodiment of the present application, a specific manner of obtaining the network type information used by the terminal to upload the location data is not limited.
In practical applications, the location data uploaded by the terminal may include: the at least two positioning modes respectively correspond to the at least two pieces of position information, and the embodiment of the present application may select the two pieces of position information respectively corresponding to the two positioning modes from the at least two pieces of position information respectively corresponding to the at least two positioning modes. Alternatively, the two position information may be selected according to the distance between the two position information. It can be understood that the embodiment of the present application does not limit the specific selection manner corresponding to the two position information.
The two positioning modes of the embodiment of the application can be both indoor positioning modes, or can be both outdoor positioning modes, or can be both indoor positioning modes and outdoor positioning modes. Optionally, the two positioning manners may include: the positioning method comprises two modes of a mobile communication network positioning mode, a WIFI positioning mode, a Bluetooth positioning mode and a GPS positioning mode. It is understood that the embodiment of the present application is not limited to the specific two positioning manners.
Taking two positioning modes as a mobile communication network positioning mode and a WIFI positioning mode as examples, it is assumed that the position information respectively corresponding to the mobile communication network positioning mode and the WIFI positioning mode is the first position information and the second position information, that is, the two position information may include: first location information and second location information. The first position information and the second position information are respectively used for representing indoor positioning results corresponding to the mobile communication network data and the WIFI data. The first position information and the second position information corresponding to the mobile communication network data and the WIFI data can be acquired by adopting any indoor positioning technology. Optionally, the mobile communication network data and the WIFI data may be respectively matched with the standard feature fingerprints in the building fingerprint library, the indoor position coordinates of the building corresponding to the successfully matched standard feature fingerprints are obtained, and the indoor position coordinates of the building are used as the first position information and the second position information of the terminal.
Taking two positioning manners as a mobile communication network positioning manner and a bluetooth positioning manner as examples, it is assumed that the position information respectively corresponding to the mobile communication network positioning manner and the bluetooth positioning manner is the first position information and the third position information, that is, the two position information may include: first location information and third location information.
The distance between the two pieces of location information can be used as a basis for determining whether location data corresponding to one of the two positioning manners is not updated. Optionally, step 202 may include: and when the absolute value of the distance between the two pieces of position information exceeds a distance threshold value, selecting one of the two pieces of position information as the position of the terminal according to the network type information when the terminal uploads the position data. For example, an absolute value of a distance between the first location information and the second location information may be used as a basis for whether one of the mobile communication network data and the WIFI data is not updated; specifically, when the absolute value of the distance between the first location information and the second location information exceeds a distance threshold, it is indicated that the proximity of the distance between the first location information and the second location information is low or the degree of deviation is high, so that it can be determined that one of the mobile communication network data and the WIFI data is not updated.
The distance threshold may be used to determine whether there is an un-updated distance threshold in the position data corresponding to one of the two positioning manners, and usually, the distance threshold is too small or too large, which easily affects the accuracy of the determination result. In practical application, a person skilled in the art can determine a reasonable distance threshold according to practical application requirements to ensure the accuracy of the judgment result.
In an alternative embodiment of the present application, the distance threshold may be determined by: and determining the distance threshold according to the coverage range corresponding to the network type information when the terminal uploads the position data. Specifically, the network type information when the terminal uploads the location data may include: mobile communication networks, WIFI networks, bluetooth networks, etc. The coverage area corresponding to the mobile communication network can be determined by the coverage area of the base station, and the base station of the mobile communication network comprises: the coverage ranges of different types of base stations are usually different, such as a GSM (Global System for Mobile Communication) base station, a CDMA (Code Division Multiple Access) base station, and the like, wherein the coverage range of the GSM base station is about 300-500 meters, the coverage range of the CDMA base station is about 1000-2500 meters, the coverage range of WIFI data is usually only 50-100 meters, and the coverage range of bluetooth data is usually only 40-50 meters.
In practical application, if the terminal uploads the location data by using one network type, the distance threshold may be determined according to a coverage area corresponding to the network type.
In an optional embodiment of the present application, a network type with a largest coverage area may be selected from the multiple network type information adopted by the terminal, for example, if the terminal uploads the location data by using a mobile communication network or a WIFI network, the distance threshold may be determined according to a coverage area of a base station corresponding to the mobile communication network data. Because the range of any base station is larger than the coverage range of the WIFI data, the corresponding distance threshold value can be determined according to the type of the preset base station, and the mapping relation between the type of the preset base station and the distance threshold value is established.
Further, the step of determining the distance threshold according to the coverage area of the base station corresponding to the mobile communication network data may include: and determining the base station type of a base station corresponding to the mobile communication network data, and determining the distance threshold according to the coverage range of the base station type. Optionally, the maximum value of the coverage range corresponding to the type may be used as the distance threshold according to a mapping relationship between a preset base station type and the distance threshold. For example, if the type of the base station corresponding to the mobile communication network data is GSM, it may be determined that the distance threshold is 500 meters, that is, when an absolute value of a distance between the first location information and the second location information exceeds 500 meters, it may be considered that a proximity and a deviation degree between the first location information and the second location information are low, that is, one of the mobile communication network data and the WIFI data is not updated; or when the absolute value of the distance between the first location and the second location information does not exceed 500 meters, it may be considered that the proximity and the deviation degree between the first location and the second location information are higher, that is, the mobile communication network data and the WIFI data correspond to the same location, that is, neither the mobile communication network data nor the WIFI data exists and is not updated. As another example, if the mobile communication network data corresponds to a base station of CSM type, the distance threshold may be determined to be 2500 meters.
When determining whether the location data corresponding to one of the two positioning manners is not updated, the embodiment of the present application may select the real location according to the network type information used when the terminal uploads the location data. Optionally, the selecting one of the two pieces of location information according to the network type information when the terminal uploads the location data may specifically include: and regarding the network type information when the terminal uploads the position data, using the position information corresponding to the positioning mode matched with the network type information as the position of the terminal. The terminal can have a certain association between the network type information used for uploading the position data and the position data corresponding to the two positioning modes, and can judge whether the network type data is matched with the positioning modes according to the association degree between the network type data and the position data corresponding to the positioning modes. For example, the mobile communication network is matched with the mobile communication network positioning mode, the WIF network is matched with the WIFI positioning mode, the bluetooth network is matched with the bluetooth positioning mode, and the like.
