The first embodiment is as follows:
the existing positioning method comprises WIFI positioning, IP positioning, LBS positioning and the like, and the inventor of the application can know through analyzing the existing positioning method that the existing positioning method is based on information in a network mode to position the user equipment, for example, in the WIFI positioning method, the user equipment is positioned based on the geographic position of an AP (access point) in a Wi-Fi mode and the like; in the IP positioning method, the user equipment is positioned based on the IP name and the like of the user equipment in a certain network mode; in the LBS positioning method, the user equipment is positioned based on the network information of the network mode in which the user equipment is currently located. However, since only the information in one network mode is obtained, the error possibly existing in the information cannot be identified, and thus the positioning accuracy is low, and since the information obtained in one network mode is less, the information which can be referred in the positioning process is less, and thus the positioning speed is low. In order to solve the above technical problem, an embodiment of the present application provides a positioning method, where in the embodiment of the present application, a user equipment is positioned by obtaining information in different network modes, so as to improve positioning accuracy and speed.
Fig. 1 shows a flowchart of a positioning method provided in an embodiment of the present application, where the positioning method is applied to a user equipment, where the user equipment includes a terminal capable of communicating with other terminals in multiple network modes, such as a mobile phone, a wearable device, and the like, and the positioning method includes:
step S11, acquiring first network information and second network information, where the first network information is network information of the user equipment in a current network mode, the second network information is network information of the user equipment in other network modes, the other network modes are network modes different from the current network mode, and the network information includes a mobile country code MCC, a mobile network number MNC, a location area code TAC, and a base station number CID.
In this embodiment, the network mode in which the ue is currently located refers to a network mode that is currently used by the ue to communicate with other devices, for example, if the network mode that is currently used by the ue to communicate with other devices is a fifth generation mobile communication technology (5th generation mobile networks, 5G), the network mode in which the ue is currently located is 5G. The network mode in which the ue is currently located may be 5G, 4G, 3G, or 2G. Of course, with the development of communication technology, the network mode in which the user equipment is currently located may also be 6G, and the like, which is not limited herein.
In this embodiment, the other network mode refers to a network mode different from the current network mode of the ue. For example, assuming that the network mode in which the user equipment is currently located is 5G, the other network modes may be 4G and/or 3G and/or 2G, etc.
In this embodiment, the ue acquires network information of the ue in a current network mode, and acquires network information of the ue in other networks to obtain corresponding first network information and second network information.
In some embodiments, after step S11, the method further includes the user equipment storing the acquired first network information and the acquired second network information.
Step S12, sending the first network information and the second network information to a location server, where the location server is configured to determine corresponding longitude and latitude information according to the received MCC, MNC, TAC, and CID.
In this embodiment, the user equipment sends the acquired first network information and second network information to the location server, or the user equipment sends the stored first network information and second network information to the location server.
The location server stores the corresponding relation between the network information (MCC, MNC, TAC and CID) and the latitude and longitude information in advance. After receiving the network information sent by the user equipment, determining corresponding longitude and latitude information, for example, after receiving the first network information and the second network information sent by the user equipment, the location server determines first longitude and latitude information corresponding to the first network information, and determines second longitude and latitude information corresponding to the second network information. That is, the location server determines the latitude and longitude information corresponding to the network information in different network modes respectively.
Step S13, receiving first longitude and latitude information corresponding to the first network information and second longitude and latitude information corresponding to the second network information, which are sent by the location server.
In this embodiment, after the user equipment sends the first network information and the second network information to the location server, the corresponding first longitude and latitude information and the corresponding second longitude and latitude information may be obtained from the location server.
It should be noted that, because the second network information is the network information corresponding to the network mode in which the non-user equipment is currently located, the second network information may include network information in a plurality of network modes, and at this time, the second longitude and latitude information corresponds to a plurality of longitude and latitude information corresponding to the network information in the plurality of network modes. For example, if the second network information includes network information under 3G and network information under 2G, the second longitude and latitude information includes longitude and latitude information corresponding to the network information under 3G and longitude and latitude information corresponding to the network information under 2G.
Step S14, positioning the ue according to the first longitude and latitude information and the second longitude and latitude information.
Because the first longitude and latitude information and the second longitude and latitude information are the position information which is determined under different network modes and used for identifying the user equipment, the position of the user equipment can be determined approximately after the user equipment acquires the first longitude and latitude information and the second longitude and latitude information, and the positioning of the user equipment can be completed quickly and accurately.
In this embodiment, the center points of the first longitude and latitude information and the second longitude and latitude information may be used as the positioning information of the user equipment, and the first longitude and latitude information and the second longitude and latitude information may also be combined with other positioning methods to realize positioning of the user equipment, which is not limited herein.
In the embodiment of the application, first network information and second network information are acquired, the first network information and the second network information are sent to a position server, first longitude and latitude information corresponding to the first network information and second longitude and latitude information corresponding to the second network information sent by the position server are received, and the user equipment is positioned according to the first longitude and latitude information and the second longitude and latitude information. Since the first network information is network information of the user equipment in a current network mode, the second network information is network information of the user equipment in other network modes, and the other network modes are usually at least 1, that is, the embodiment of the present application can acquire network information of at least 2 network modes, so that at least 2 corresponding latitude and longitude information can be acquired from the location server according to the network information of the at least 2 network modes. Compared with the positioning of the user equipment according to the 1 piece of longitude and latitude information, the method and the device can improve the positioning accuracy and speed when the user equipment is positioned according to the at least 2 pieces of corresponding longitude and latitude information because the longitude and latitude information used for positioning is more and is obtained from different network modes.
In some embodiments, since the number of other network modes is greater than or equal to 1:
if the number of the other network modes is 1, the acquiring the second network information includes: and after the user equipment is switched to the other network mode, registering the other network mode, and if the other network mode is successfully registered, acquiring the network information of the user equipment in the other network mode.
If the number of the other network modes is greater than 1, the acquiring the second network information includes: selecting one of the other network modes, registering the selected network mode after the user equipment is switched to the selected network mode, if the selected network mode is registered successfully, acquiring network information of the user equipment in the selected network mode, and returning to the step of selecting one of the other network modes and the subsequent steps until the network modes of the other network modes are all selected, wherein the acquired network information of the user equipment in each selected network mode is the acquired second network information.
In this embodiment, if the number of the other network modes is greater than 1, the user equipment needs to register to different network modes one by one to acquire network information in different network modes. For example, if the current network mode of the user equipment is 5G, and the other network modes are 4G, 3G and 2G, it is assumed that the 4G network mode is selected first, and if the user equipment successfully registers the 4G network mode, network information of the user equipment in the 4G network mode is acquired; then, selecting a 3G network mode, and if the user equipment successfully registers the 3G network mode, acquiring network information of the user equipment in the 3G network mode; and finally, selecting a 2G network mode, and if the user equipment successfully registers the 2G network mode, acquiring the network information of the user equipment in the 2G network mode. And the network information acquired by the user equipment at 4G, 3G and 2G forms second network information acquired by the user equipment. Since 4G, 3G, and 2G have all been selected, acquisition of the second network information is stopped.
In some embodiments, in order to quickly acquire the network information in the different network modes, the acquiring the second network information further includes:
if the selected network mode is not registered successfully, judging whether the registration time length exceeds a preset time length threshold value, if not, continuing to try to register to the selected network mode, and if the preset time length threshold value is exceeded, returning to the step of selecting one network mode of other network modes and the subsequent steps, wherein the registration time length is used for representing the time length of the user equipment trying to register to the selected network mode.
The preset time threshold may be 2 seconds, 3 seconds, or the like, and of course, may also be other time durations, which is not limited herein. In some embodiments, in order to reduce the time period for acquiring the network information, i.e., in order to avoid the positioning time period being too long, the preset time period threshold is set to be less than or equal to 5 seconds.
In this embodiment, if the user equipment is not successfully registered in the selected network mode, it is determined whether the registration time length exceeds a preset time length threshold, if so, a new network mode is reselected for registration, and otherwise, the user equipment continues to try to register in the selected network mode. For example, if the ue fails to attempt to register in the 4G network mode and determines that the registration duration exceeds the preset duration threshold (e.g. exceeds 3 seconds), the 3G network mode is selected and attempts to register in the 3G network mode.
In some embodiments, after the obtaining the second network information, considering that the positioning accuracy and the speed of the user equipment are related to the number of network information included in the second network information, the method includes: and judging whether the number of the network information included in the second network information is smaller than a preset number threshold, if so, retrying to register to a network mode in which the network information is not acquired, and acquiring the network information in the corresponding network mode after the registration is successful.
For example, assuming that the network mode in which the user equipment is currently located is 5G, and the second network information includes network information in 4G, in order to improve the speed and accuracy of subsequent positioning of the user equipment, registration to the 3G network mode and the 2G network mode is retried, so as to obtain the network information in the 3G network mode and the 2G network mode, respectively. In this embodiment, the user equipment re-registers to the network mode in which the network information is not acquired, so as to increase the number of network information included in the second network information, thereby increasing the positioning accuracy and the positioning speed of the user equipment.
In some embodiments, it is considered that a certain time duration is required for acquiring the network information, and therefore, in order to avoid that the positioning time duration of the ue is too long, after the acquiring the second network information, the method includes: judging whether the duration for acquiring the second network information is less than a preset duration threshold, if so, retrying to register to a network mode in which the network information is not acquired, and acquiring the network information in the corresponding network mode after the registration is successful.
For example, if the second network information includes network information 1 in a 4G network mode and network information 2 in a 4G network mode, and the duration for acquiring the network information 1 is 2 seconds, and the duration for acquiring the network information 2 is 3 seconds, the duration for acquiring the second network information is 2+ 3-5 seconds.
In some embodiments, the step S14 includes:
a1, determining an area for positioning according to the first longitude and latitude information and the second longitude and latitude information.
A2, positioning the user equipment in the positioning area.
The shape of the area for positioning may be circular or rectangular, etc.
In this embodiment, the user equipment may be located by combining with other locating methods, for example, locating the user equipment by combining with a Global Navigation Satellite System (GNSS), specifically, first, an area for locating the user equipment is determined according to the first longitude and latitude information and the second longitude and latitude information, and then, accurate locating of the user equipment is achieved in the determined area by using the GNSS. Of course, in practice, the method may be combined with other positioning methods, and is not limited herein.
In some embodiments, if the second longitude and latitude information includes at least 2 pieces of longitude and latitude information and the area for positioning is a circular area, the determining an area for positioning according to the first longitude and latitude information and the second longitude and latitude information includes:
and B1, determining a first minimum circumcircle comprising the first longitude and latitude information and the second longitude and latitude information.
And B2, if the radius of the first minimum circumcircle is smaller than a preset radius threshold, taking the area where the first minimum circumcircle is located as an area for positioning.
B3, if the radius of the first minimum circumcircle is larger than or equal to the preset radius threshold, determining abnormal longitude and latitude information in the first longitude and latitude information and the second longitude and latitude information, and determining a second minimum circumcircle according to non-abnormal longitude and latitude information in the first longitude and latitude information and the second longitude and latitude information, wherein the area where the second minimum circumcircle is located is used as the area for positioning, the longitude and latitude information corresponding to the distance threshold value that the distances between the first longitude and latitude information and the M longitude and latitude information are larger than or equal to the preset distance threshold value in the first longitude and latitude information and the second longitude and latitude information is used as abnormal longitude and latitude information, M is an integer, and M is larger than half of the number of all the longitude and latitude information included in the first longitude and latitude information and the second longitude and latitude information.
In this embodiment, the first longitude and latitude information includes only longitude and latitude information corresponding to the network information of the user equipment in the current network mode, so that the first longitude and latitude information includes only one longitude and latitude information, and the second longitude and latitude information includes at least one longitude and latitude information corresponding to the network information in at least one network mode. Assuming that the first longitude and latitude information and the second longitude and latitude information include X longitude and latitude information, wherein M is greater than X/2, if the distances between certain longitude and latitude information and the M longitude and latitude information (assumed distances are M1, M2 and MM respectively) are greater than or equal to a preset distance threshold, determining that the certain longitude and latitude information is abnormal longitude and latitude information, at the moment, eliminating the abnormal longitude and latitude information, determining a second minimum circumscribed circle only according to the non-abnormal longitude and latitude information (namely normal longitude and latitude information), and determining the area where the second minimum circumscribed circle is located, namely the area for positioning the user equipment. As shown in fig. 2, assuming that the distance between N3 and N1 and the distance between N3 and N2 are both greater than the preset distance threshold, a second minimum circumscribed circle is determined according to N1 and N2, and the area where the second minimum circumscribed circle is located is the area for locating the user equipment.
In some embodiments, before the step S11, the method includes:
and starting a predefined multi-network mode positioning function, wherein the predefined multi-network mode positioning function is used for acquiring the first network information and the second network information.
After the step S11, the method includes:
turning off the positioning function of the multi-network mode.
In this embodiment, a setting page of the user equipment may provide setting options for turning on and off the predefined multi-network-mode positioning function, and after the user turns on the predefined multi-network-mode positioning function, the user equipment may obtain the first network information and the second network information. In consideration of the fact that the user equipment needs to be switched without stopping in different network modes to acquire the network information in the corresponding network mode when acquiring the second network information, and the user equipment is not beneficial to the communication between the user equipment and other equipment when being switched without stopping in different network modes, the user equipment automatically closes the positioning function in the predefined multi-network mode after acquiring the first network information and the second network information.
In some embodiments, after turning off the positioning function of the multi-network mode, the method comprises: the user equipment switches to the general network mode. The general network mode is that the user equipment adaptively selects a certain network mode and communicates with other equipment in the network mode. For example, in a general network mode, the user equipment may adaptively select a corresponding network mode among 5G, 4G, 3G, and 2G.
In some embodiments, before the step S12, the method includes:
and detecting whether the data service of the user equipment is normal.
The step S12 includes:
and if the data service of the user equipment is normal, sending the first network information and the second network information to a position server.
The user equipment can judge whether the data service of the user equipment is normal or not by checking whether the data network setting item of the user equipment is opened or not.
In this embodiment, the user equipment sends the first network information and the second network information to the location server only when judging that the data service is normal, so that the success rate of sending can be improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
